5,432,395 | 1 | 5,442,036 | null | 7 | 1,566 | Is there any way to create a custom `FrameworkContentElement` (or an `Inline`) that draws a diagonal line over its content?
Something like Strike-through decoration but with a diagonal shape:
It is not possible to inherent from `TextDecoration` or `TextEffect` (they are sealed).
Any idea?

5,432,854 | 1 | 5,437,910 | null | 1 | 376 | I'm super new to rails and javascript, I have a table of venues with each belonging to a type and an area. They are displayed as partials on the index page and also each has its own icon on a map to the left of the screen.
I have just added a new table of mapicons which just holds an image uploaded using paperclip to my app so each venuetype has a differant icon. This all works fine however the javascript I was using to place the icons on the map breaks when I include the new mapicon.
```
<%= link_to venue do %>
<div class="venue_partial">
<span class="venue_partial_name"><%= venue.name %></span>
<div id="venue_map_icon_<%= venue.id %>" class="venue_map_icon" style="position:absolute;"></div>
</div>
<% end %>
<script type="text/javascript">
document.getElementById("venue_map_icon_<%= venue.id %>").style.left= "<%= venue.iconleftpx %>px";
document.getElementById("venue_map_icon_<%= venue.id %>").style.top= "<%= venue.icontoppx %>px";
</script>
```
Displays the map icon correctly on the map but as black stars as I have set in the css.
```
<%= link_to venue do %>
<div class="venue_partial">
<span class="venue_partial_name"><%= venue.name %></span>
<div id="venue_map_icon_<%= venue.id %>" <%= image_tag venue.venuetype.mapicon.mapicon.url(:mapicon), :style => "position:absolute;", :class => "venue_map_icon" %></div>
</div>
<% end %>
<script type="text/javascript">
document.getElementById("venue_map_icon_<%= venue.id %>").style.left= "<%= venue.iconleftpx %>px";
document.getElementById("venue_map_icon_<%= venue.id %>").style.top= "<%= venue.icontoppx %>px";
</script>
```
Displays the correct mapicons that I uploaded and assigned to each venuetype but they are positioned at the top right corner of their venue partial and not on the map to the left of the screen.
Hope I've asked this well, any clarification needed please ask. Thanks for any help its much appreciated!
Heres a couple of screenshots I hope will help, The first is how the mapicons are currently. The venue partials show as Tester1, Tester2 etc with a large coloured icon to the left of the name, the grayed lettering under the name is the type (Type 1, 2 or 3). And the map icons are the black stars to the left positioned absolutely with the top and left values taken from their respective venue records.
The second screenshot is when I change the code as shown above, the partials show the same but the mapicons instead of being black stars show correctly as smaller coloured squares but aren't positioning correctly. They are sticking to the top right corner of their own venue partials.
This is what I want it to display as: (this is a mocked-up image)
The CSS for the mapicons is just:
```
.venue_map_icon {
width: 19px;
height: 18px;
padding: none;
margin: none;
background-image:url(/images/mapicon.png);
border: none;
}
.venue_map_icon:hover {
background-image:url(/images/mapicon_hover.png);
}
```

```

5,433,345 | 1 | 5,449,628 | null | 0 | 160 | I created a UIViewController (based on [How to switch views when rotating](https://stackoverflow.com/questions/2267117/how-to-switch-views-when-rotating)) to switch between 2 views when the device rotates. Each view is "specialized" for a particular orientation.
It uses the UIDeviceOrientationDidChangeNotification notification to switch views:
```
-(void) deviceDidRotate: (NSNotification *) aNotification{
UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];
NSLog(@"Device rotated to %d!", orientation);
if ((orientation == UIDeviceOrientationPortrait) ||
(orientation == UIDeviceOrientationPortraitUpsideDown)) {
[self displayView:self.portraitViewController.view];
}else if ((orientation == UIDeviceOrientationLandscapeLeft) ||
(orientation == UIDeviceOrientationLandscapeRight)) {
[self displayView:self.landscapeViewController.view];
}
}
```
and sort of works. The problems shows up when I rotate to Landscape and then back to Portrait. When going back to portrait the subviews aren't displayed in the right place, specially the UIPickerView:

If I repeat the rotation process, things just get worse. What am I doing wrong?

@for (int i = 0; i < Model.AgentTypes.Length; i++)
{
@Html.DropDownListFor(m => m.AgentTypes[i], Model.AgentTypeListItems)

```
The controller method initializes AgentTypeListItems collection + sets default values for AgentType dropdown and 3 dropdowns for the collection:
```
var model = new OptionsViewModel();
// for DropDownListFor
model.AgentTypeListItems = new[]
{
new SelectListItem { Text = "1", Value = "1" },
new SelectListItem { Text = "2", Value = "2" },
new SelectListItem { Text = "3", Value = "3" },
};
// 1 dropdown in the model
model.AgentType = "2";
// 3 dropdowns in array
model.AgentTypes = new[] { "3", "2", "1" };
return View(model);
```
When I open it in browser I get "2" everywhere though AgentTypes array was initialized with different values(!):
When I replace DropDownListFor with TextBoxFor:
```
@Html.TextBoxFor(m => m.AgentTypes[i])
```
I get the correct values in the inputs (!):
It means the TextBoxFor works as expected, but DropDownListFor doesn't.
Is it a bug in MVC DropDownListFor?
Here is the model class:
```

5,434,635 | 1 | 5,459,624 | null | 4 | 3,175 | I'm been reading, and have now seen two different implementations of the Unit of Work pattern. The first pattern has the Repository talking to the Unit of Work to a domain object.
The other implementation has the Service layer registering the domain object as modified:
I guess my question is, what are the benefits/drawbacks to each? I know that is lot to answer without providing some implementation code for the repositories/mappers/etc... but in general, who/what should really be responsible for "newing up" the UoW and then working with it?
My thought is if you let the Repository handle it, it should be provided as a injectable interface to the repository(s) so the same UoW can span multiple repositories (aka, multiple domain objects)...
If the service layer handles it, then you're kind of "stuck" with only one UoW implementation per Service Layer call (example, ServiceLayer.AddCustomer(customer)).
In the web world, I can't see multiple service layers being called for different domain objects... but maybe in the non-web world I can.
I imagine something eventually has to call "commit()", so it makes the most sense to have that tied into the Service Layer.
Thanks,
Mike

5,435,084 | 1 | null | null | 0 | 180 | i am using jquery ui tabs for my own custom image gallery, so i didn't load the css it comes with. in firefox there is nothing wrong, but in IE and chrome there is this dash character.
in the view source you don't see it, but Inspect Element in chrome shows me:
```
<li class="ui-state-default ui-corner-top"><a href="#tab-9">_</a></li>
```
I tried doing something like `.ui-corner-top{display:none !important;}` but that kills off the tabs completely.

5,435,806 | 1 | 5,439,410 | null | 9 | 2,021 | I'm working on a Tetris-type HTML5 game and need to beef up a space optimization algorithm.
Rectangular blocks of varying size need to be added to the canvas in the most space efficient way. I know how much space the block takes, I need to find the closest spot the block can be added with a fixed x coordinate- the absolute closest spot is a nice to have.
I've implemented a version that searches using pixel by pixel value checking on the canvas that pushes down until it finds enough free space for the shape and then adds it. This works (slowly) only if the space fills left to right- the algorithm can safely assume if the first pixel column is safe then the entire block can be added.
I need to make this more robust, here's where I think this should go.
Storing a quad tree to represent the board state gives me a quicker way to identify where there's space.
4 nodes are stored for each level of depth- each node is either 0 for completely empty, or 1 for 'has some stuff somewhere'. Each progressive level of depth gives more and more information about the board.
```
given(boardstate, block width, block height)
-calculate the largest grid space the block must span
// a block which is 242x38 MUST span a 16x16 free space
// (based on 1/2 of smallest dimension)
-the block width requires n consecutive free spaces
// (242/16) = 15
-find the first available 15x1 spaces in the board
-check the surrounding tiles at the next level of depth for collisions
-check the surrounding tiles at the next level of depth for collisions... etc
-if there's a fit
draw the block
mark all affected nodes at all depths as 'filled'
```
Things I've considered so far:
A. Build a full `tree` object with pointers to children and values and a set of methods to navigate it. This would be intuitive and probably space-efficient, but I suspect horribly slow.
B. Look at each grid as 4 bits and store the depths as hex arrays or objects. If done by a person more clever than myself, this probably optimizes not just the storage but makes clever bit operations available to compare adjacent cells, turn blocks on and off, etc. I imagine it would be incredibly fast, incredibly efficient, but it's beyond my skills to build.
C. Store each depth in an array. `Depth[0]=[1,0,0,0]; Depth[1][1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0]` etc. This is where I'm headed at the moment. It's not very space efficient and it probably won't be incredibly fast, but I think I can get my head around it.
There's a practical limit to any structure to the number of depths (the array to store availability of 4x4 spaces in my last approach is more than 65 thousand) after which making the expensive call to check the last few pixels of image data from the canvas with a regular iterator is unavoidable.
So, A,B,C, other?
As usual, all insights appreciated.

5,435,883 | 1 | 5,439,487 | null | 14 | 7,301 | My troubles started when I had a variable with more than 6 values because that is the current maximum value for the scale_shape function in ggplot2.
Due to that problem I tried a work-around with another variable that I just wrapped around the length of the original variable.
Here is my example code:
```
dataf <- structure(list(Municipality = structure(c(2L, 4L, 10L, 11L, 6L, 8L, 3L, 1L, 5L, 9L, 7L), .Label = c("Boyuibe", "Cabezas", "Camiri", "Charagua", "Cuevo", "Gutierrez", "Huacaya", "Lagunillas", "Machareti", "Vallegrande", "Villa Vaca Guzman"), class = "factor"), Growth = c(3.05, 2.85, 0.14, 1.21, 1.59, 2.35, -0.41, 0.81, 0.9, 2.89, 1.8), Density = c(3.0390920594, 0.260984024187, 5.20069847261, 2.50828556783, 3.43964629267, 3.69768961375, 32.4496626479, 2.06145019368, 4.2139578988, 0.740736713557, 1.67034079825)), .Names = c("Municipality", "Growth", "Density"), class = "data.frame", row.names = c(NA, -11L))
dataf <- dataf[with(dataf, order(Municipality)), ]
# create a new column with values 1 to 6 and same length as Municipality
modulus <- function(x) (x - 1) %% 6 + 1
indeces <- 1:length(dataf$Municipality)
dim(indeces) <- length(dataf$Municipality)
dataf$Shape <- apply(indeces, 1, modulus)
dataf$Shape <- factor(dataf$Shape, levels=unique(dataf$Shape))
plot1 <- ggplot(dataf, aes(x=Density, y=Growth, colour=Municipality,
shape=Shape))
plot1 <- plot1 + geom_point(size=3)
plot1 <- plot1 + scale_x_continuous(expression(paste(
"Population Density [people per km"^2, "]", sep="")))
plot1 <- plot1 + scale_y_continuous("Growth Rate [ratio population 2001 /
population 1992]")
plot1 <- plot1 + scale_colour("Municipality")
plot1
```
that produces the following output:
I would like the legend to be just like the points in the plot. Is that possible, or is there a smart solution to my first problem with the list of municipalities being too long?
Thanks in advance.

5,436,392 | 1 | null | null | 1 | 2,803 | Herro. I have a strange problem that I am dealing with that involves two buttons, an HTML (client-side "Export to Excel") and an ASP (server-side "Go") button:
Here is the html for the two buttons:
```
<asp:Button ID="btnGo" runat="server" Text="Go" OnClick="btnGoClick" Width="35px" />
<input id="btnExport" type="button" value="Export to Excel" disabled="disabled" onclick="btnExClick(this)" onmouseover="return doHover(this)" onmouseout="this.style.backgroundColor='';" style="width: 125px" />
```
Basically the user selects in the drop down, what loans to load, and clicks "Go", which queries the database and loads the data grid. When a datagrid is loaded the "Export to Excel" button becomes enabled and will turn to and from the color green when the user hovers the mouse over and off. When clicked, it fires and event that just calls `__doPostBack(btnEx.id, '');`
Here is my btnExClick():
```
function btnExClick(btn)
{
document.forms[0].target = "_blank"; //newly added line from shadowwizard
__doPostBack(btn.id, '');
}
```
In my code-behind, I have the following code:
```
protected void Page_Load(object sender, EventArgs e)
{
.....
if (Request.Form["__EVENTTARGET"] == "btnExport")
{
this.ExportExcel();
}
}
protected void ExportExcel()
{
Response.Clear();
Response.Buffer = true;
Response.ContentType = "application/vnd.ms-excel";
Response.AddHeader("content-disposition", "attachment;filename=Optoma Loaner Report.xls");
Response.Charset = "";
this.EnableViewState = false;
System.IO.StringWriter sw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htw = new System.Web.UI.HtmlTextWriter(sw);
dgResults.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();
}
```
This all works fine, and I get a nice looking Excel sheet. The only problem is after I "Export to Excel", my "Go" button no longer works. It just performs a "postback" with an __EVENTTARGET still = "btnExport", so it attempts to export to excel again.. It doesn't even go to its server-side onclick event handler! Does anyone know why this is happening?
I'm assuming it has something to do with the way I export my datagrid to an excel sheet, because when I comment out `this.ExportExcel();`, it continues to work fine (although the "Export to Excel" button goes back to being disabled after I click it, and I'm not sure why. It doesn't normally do that).

5,436,897 | 1 | 5,437,509 | null | 3 | 3,226 | I'm creating a webpage where I need a content column in the center of the page (including a fixed width) and two non-scrollable (fixed) columns at the left and the right side of that content column (including a fixed width also). The left column needs to be aligned to the left side of the middle content column. The right column needs to be aligned to the right side of the middle content column.
If the content column gets a lot of content the middle content column should be scrollable with a scrollbar at the right side of the browser. But the left and right columns must not scroll, but stay fixed against the top of the browser.
When resizing the browser width then the left+middle+right columns keeps their width and centered in the middle of the webpage. At the left side of the left column and at the right side of the right column the whitespace will increase/decrease on both sides with same width.

from the FieldTypes enum.

```

</DataTemplate>
</DataGridTemplateColumn.CellTemplate>

```
The other columns are binding the data correctly, but this one is not.
I am not sure if there is a better way to do it or not. I have also written a EnumConverter from the IValueConverter to handle the string-enum-string conversions if that is ever needed.

5,439,096 | 1 | null | null | 2 | 1,219 | I'm working on an Android game and would like to implement a 2D grid to visualize the effects of gravity on the playing field. I'd like to distort the grid based on various objects on my playing field. The effect I'm looking for is similar to the following from the Processing library:
Except that my grid will be simpler- 2D, and viewed strictly from the top, as if looking down at the playfield.
Can someone point me to an algorithm for drawing such a grid?
The one idea that I came up with was to draw the lines as if they were "particles"- start at one end of the screen and draw the line in multiple segments, treating each segment as a particle, calculating the effect of gravity at each segment's location.
The application is intended to run on Android.
Thanks

5,441,061 | 1 | 5,477,681 | null | 7 | 5,047 | Does anyone have a good algorithm for calculating the end point of `ArcSegment`? This is not a circular arc - it's an elliptical one.
For example, I have these initial values:
- - - - - -
I know the location that my arc should end up at is right around X=0.92 and Y=0.33 (through another program), but I need to do this in an `ArcSegment` with specifying the end point. I just need to know how to calculate the end point so it would look like this:
```
<ArcSegment Size="0.436,0.593" Point="0.92,0.33" IsLargeArc="False" SweepDirection="Clockwise" />
```
Does anyone know of a good way to calculate this? (I don't suppose it matters that this is WPF or any other language as the math should be the same).
Here is an image. All values are known in it, except for end point (the orange point).
---
I've found that there is a routine called [DrawArc with an overload in .NET GDI+](http://msdn.microsoft.com/en-us/library/xxw9hsz1.aspx) that pretty much does what I need (more on the "pretty much" in a sec).
To simplify viewing it, take the following as an example:
```
Public Sub MyDrawArc(e As PaintEventArgs)
Dim blackPen As New Pen(Color.Black, 2)
Dim x As Single = 0.0F
Dim y As Single = 0.0F
Dim width As Single = 100.0F
Dim height As Single = 200.0F
Dim startAngle As Single = 180.0F
Dim sweepAngle As Single = 135.0F
e.Graphics.DrawArc(blackPen, x, y, width, height, startAngle, sweepAngle)
Dim redPen As New Pen(Color.Red, 2)
e.Graphics.DrawLine(redPen, New Point(0, 55), New Point(95, 55))
End Sub
Private Sub ImageBox_Paint(sender As Object, e As System.Windows.Forms.PaintEventArgs) Handles ImageBox.Paint
MyDrawArc(e)
End Sub
```
This routine squarely puts the end point at `X=95, Y=55`. Other routines mentioned for circular ellipses would result in `X=85, Y=29`. If there was a way to Not have to draw anything and have `e.Graphics.DrawArc` return the end-point coordinates, this is what I would need.
So now the question gains some clarity - does anyone know how `e.Graphics.DrawArc` is implemented?

```

Border border = new Border();
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_LEFT, bored);
params.addRule(RelativeLayout.ABOVE, bored);
this.addView(border,params);
```
This gives me a Border object aligned_left with my RelativeLayout but NOT "ABOVE" (technically, it is above it, but it's at the top of the screen not aligned the way it's supposed to be). And, even stranger, when I do this:
```
int bored = board.getId();
Border border = new Border();
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_LEFT, bored);
params.addRule(RelativeLayout.BELOW, bored); //<---The only difference
this.addView(border,params);
```
...it works perfectly. it is aligned left and below in the ways that are expected. Why is the ABOVE attribute giving me such a hard time?
Edit:
ABOVE is supposed to align the bottom edge of one view with the top edge of the target. Here is a screen shot of how my project is not working as intended.
The green bar at the top of the screen is the Border object I am trying to align. As you can see, its left edge is aligned with "board" however it is in the wrong place at the top of the screen.

5,441,662 | 1 | 5,441,867 | null | 3 | 26,632 | Sorry to bring this up again since I am quite sure it was answered in threads like [here](https://stackoverflow.com/questions/4353398/changing-the-property-of-outer-div-while-hovering-over-inner-a-element), yet posting in older threads appears to be pointless. But I'd like to know whether this is still true that I will in fact need jQuery (or something similar) in order to change the properties of one div-element when hovering above some other div-element?
If the answer would still be yes, please have a look at the following picture:
This is part of my navigation I am trying to bring to life right now. As you can see there is some kind of mirror effect underneath the buttons. I want those buttons to be clickable while having a "hover" background-position / background-image change. I tried to do that with a single div-element which didn't work out since the button-area itself is smaller than the entire graphic so even when I was hovering above the reflection the button was ready to be used which was not very intuitive.
Currently I am using a div-element to display the background image including the hover effect and - sorry but I don't really know how to describe the following - some kind of "invisible" text link which is forced to a specific size in order to simulate a clickable area. Here a small visualization:
Green is the area of the background image which is changing upon hovering above the div-element and the red area is the "button".
So again the question ... do I still need something like jQuery to get this hover effect working only when I hover above the button area, are there different approaches to this or ... is something like jQuery really the only answer to that?

My question is this. How can a hacker use this information? How does a call stack of basic operations of the .NET call stack help hackers?
I attached a yellow screen of death that I encountered on one of the websites that I created a long time ago and it sparked my interest.
(The error is that it fails when attempting to cast a query string parameter to an int. Yea, I know its bad code, I wrote it many years ago ;)

5,443,345 | 1 | null | null | 3 | 3,024 | I have some problems figuring out where my error is. I got the following:
Have an image and corresponding GPS coordinates of its top-left and bottom-right vertices.
E.g:
```
topLeft.longitude = 8.235128;
topLeft.latitude = 49.632383;
bottomRight.longitude = 8.240547;
bottomRight.latitude = 49.629808;
```
Now a have an Point that lies in that map:
```
p.longitude = 8.238567;
p.latitude = 49.630664;
```
I draw my image in landscape fullscreen (1024*748).
Now I want to calculate the exact Pixel position (x,y) of my point.
For doing that I am trying to use the great circle distance approach from here: [Link](http://dotnet-snippets.de/dns/c-berechnung-der-entfernung-zwischen-gps-koordinaten-SID1179.aspx).
```
CGFloat DegreesToRadians(CGFloat degrees)
{
return degrees * M_PI / 180;
};
- (float) calculateDistanceP1:(CLLocationCoordinate2D)p1 andP2:(CLLocationCoordinate2D)p2 {
double circumference = 40000.0; // Erdumfang in km am Äquator
double distance = 0.0;
double latitude1Rad = DegreesToRadians(p1.latitude);
double longitude1Rad = DegreesToRadians(p1.longitude);
double latititude2Rad = DegreesToRadians(p2.latitude);
double longitude2Rad = DegreesToRadians(p2.longitude);
double logitudeDiff = fabs(longitude1Rad - longitude2Rad);
if (logitudeDiff > M_PI)
{
logitudeDiff = 2.0 * M_PI - logitudeDiff;
}
double angleCalculation =
acos(sin(latititude2Rad) * sin(latitude1Rad) + cos(latititude2Rad) * cos(latitude1Rad) * cos(logitudeDiff));
distance = circumference * angleCalculation / (2.0 * M_PI);
NSLog(@"%f",distance);
return distance;
}
```
Here is my code for getting the Pixel position:
```
- (CGPoint) calculatePoint:(CLLocationCoordinate2D)point {
float x_coord;
float y_coord;
CLLocationCoordinate2D x1;
CLLocationCoordinate2D x2;
x1.longitude = p.longitude;
x1.latitude = topLeft.latitude;
x2.longitude = p.longitude;
x2.latitude = bottomRight.latitude;
CLLocationCoordinate2D y1;
CLLocationCoordinate2D y2;
y1.longitude = topLeft.longitude;
y1.latitude = p.latitude;
y2.longitude = bottomRight.longitude;
y2.latitude = p.latitude;
float distanceX = [self calculateDistanceP1:x1 andP2:x2];
float distanceY = [self calculateDistanceP1:y1 andP2:y2];
float distancePX = [self calculateDistanceP1:x1 andP2:p];
float distancePY = [self calculateDistanceP1:y1 andP2:p];
x_coord = fabs(distancePX * (1024 / distanceX))-1;
y_coord = fabs(distancePY * (748 / distanceY))-1;
return CGPointMake(x_coord,y_coord);
```
}
x1 and x2 are the points on the longitude of p and with latitude of topLeft and bottomRight.
y1 and y2 are the points on the latitude of p and with longitude of topLeft and bottomRight.
So I got the distance between left and right on longitude of p and distance between top and bottom on latitude of p. (Needed for calculate the pixel position)
Now I calculate the distance between x1 and p (my distance between x_0 and x_p) after that I calculate the distance between y1 and p (distance between y_0 and y_p)
Last but not least the Pixel position is calculated and returned.
The Result is, that my point is on the red and NOT on the blue position:
Maybe you find any mistakes or have any suggestions for improving the accuracy.

# Solved
`this` wasn't the problem, since it's being implicitly cast to `IFramework` anyway.
I was concerned it may have to do with my methods not returning `HRESULT`, or with my stubby implementations of `IUnknown::QueryInterface`, but the real problem was merely a compiler setting that had overridden several macros I needed for common calling conventions (perhaps I should have included them in the question). This had corrupted the stack.
It's interesting though, that it worked will all compilers I tested, even without implementing IUnknown at all - a little research suggests that all serious Windows compilers handle abstract C++ interfaces the same way - namely as a virtual table specifically to be used as a COM interface.

Hi. I'm trying to create an extensible application framework. My basic concept is this:
The "Framework" box will build an .exe whereas the multiple "Plugin" boxes will build .dll files.
However, my implementation is apparently flawed. I have an idea what's the problem, but I'm running out of workarounds. I've done it exactly like this with .NET projects, but the problem I have now didn't apply to the C# environment.
Consider these interfaces:
```
class IFramework
{
public:
virtual void FrameworkMethod() = 0;
};
class IPlugin
{
public:
virtual void PluginMethod() = 0;
virtual void PluginCallbackTest() = 0;
virtual void SetFramework(IFramework *framework) = 0;
};
```
Implementation of the framework:
```
class CFramework : IFramework
{
public:
void FrameworkMethod(); // printf("FrameworkMethod");
void DoSomething(); // this is the testbench basically, see below
};
```
And the implementation of the plugin:
```
class CPlugin : public IPlugin
{
IFramework *Framework;
public:
void PluginMethod(); // printf("PluginMethod");
void PluginCallbackTest(); // Framework->FrameworkMethod();
void SetFramework(IFramework *framework); // Framework = framework;
};
// plugin factory -> COM interface
extern "C" PLUGIN_API IPlugin *GetPlugin(); // return new CPlugin;
```
Now to demonstrate that this concept doesn't work:
```
void CFramework::DoSomething()
{
HMODULE PluginHandle = LoadLibrary(...); // explicit linking
auto GetPlugin = ((IPlugin *)(*)())GetProcAddress(...);
IPlugin *plugin = GetPlugin();
plugin->PluginMethod();
// up until here everything's perfectly COM-compliant and works super
plugin->SetFramework(this); // <-- that is the problem
plugin->PluginCallbackTest(); // <-- runtime crash if compiler differs
FreeLibrary(PluginHandle);
}
```
The problem is that the `SetFramework(this)` doesn't work like COM. It's not that it just feels wrong to write it like this - I can't implement a working plugin with a compiler that differs from the one I used to build CFramework (runtime crashes).

5,446,687 | 1 | 5,447,075 | null | 0 | 675 | I use hibernate as the ORM framework,and this is my first time use it for writing operation.
Befor this appliction,I just use hibernate to read data from the db.
In my struts action,I try to update a entity named "Task",this is the form in the update page:
```
<s:form action="task_update" namespace="/common" cssStyle="width:95%">
<s:textfield value="%{task.id}" cssStyle="display:none" name="task.id"></s:textfield>
<s:textfield name="task.name" value="%{task.name}" label="TaskName"/>
<s:select list="task.managers"
listKey="id" listValue="name" label="Manager" value="%{task.manage}" name="task.department.id">
</s:select>
<s:select list="#session.current_user.departments"
listKey="id" listValue="name" label="Departmentn of this task" value="%{task.department.{id}}" name="task.department.id">
</s:select>
<table>
<caption align="left">Steps</caption>
<tr>
<th>Name</th>

Then in the struts2 action,I get the task object created by struts2(The "task" object in the following example),and find the being updated object in the db(the "task_db" object in the following example):
```
public String task_update{
DozerBeanMapper dbm = new DozerBeanMapper();
// the 'task' object is created by struts2
taskid = task.getId();
String name_st = task.getName();
int dep_id_st = task.getDepartment().getId();
List<TaskStep> steps_st = task.getSteps();
TaskDaoImpl tkDao = new TaskDaoImpl();
TaskStepDaoImpl tsDao = new TaskStepDaoImpl();
OperatorDaoImpl opDao = new OperatorDaoImpl();
DepartmentDaoImpl depDao = new DepartmentDaoImpl();
List<TaskStep> step_db = new ArrayList<TaskStep>();
for (TaskStep step_st : steps_st) {
int tsid = step_st.getId();
TaskStep ts_db = tsDao.queryStepById(tsid);
if (ts_db == null) {
ts_db = step_st;
} else
dbm.map(step_st, ts_db);
// sest the operators
List<Operator> ops_to_db = new ArrayList<Operator>();
for (Operator op_st : step_st.getOperator()) {
ops_to_db.add(opDao.queryOperatorById(op_st.getId()));
}
ts_db.setOperator(ops_to_db);
step_db.add(ts_db);
}
//set the id of the task have the same id with task_db,so set its id to a unimpossible value
task.setId(-100);
//set it to null!
task=null;
Task task_db = tkDao.queryTaskById(taskid);
task_db.setName(name_st);
task_db.setDepartment(depDao.queryDepartById(dep_id_st));
task_db.setSteps(step_db);
tkDao.updateTask(task_db);
}
```
When I submit the form,I got the "org.hibernate.NonUniqueObjectException:":
a different object with the same identifier value was already associated with the session: [com.infomanager.entity.Task#4].
I wonder why? I have set the task's id to -100,and set it to null.
What is the problem?

5,447,050 | 1 | 5,449,860 | null | 3 | 4,013 | I'm trying to use the GridBagLayout layout manager to achieve this:
However, what I am currently getting is this:
The problem being that the orange and brown/gray panels are supposed to occupy the second column, but seem to only want to occupy the third when it comes to running the code.
The code that I'm using for the layout:
```
Container contentPane = form.getContentPane();
contentPane.setLayout(new GridBagLayout());
GridBagConstraints c = new GridBagConstraints();
JPanel pnlGame = new JPanel();
pnlGame.setBackground(Color.green); //temp
c.gridx = 0;
c.gridy = 0;
c.gridwidth = 2;
c.gridheight = 2;
c.fill = GridBagConstraints.BOTH;
c.weightx = 0.85;
c.weighty = 0.65;
contentPane.add(pnlGame, c);
JPanel pnlBuy = new JPanel();
c.gridx = 2;
pnlBuy.setBackground(Color.blue); //temp
c.gridy = 0;
c.gridwidth = 1;
c.gridheight = 1;
c.fill = GridBagConstraints.BOTH;
c.weightx = 0.15;
c.weighty = 0.46;
contentPane.add(pnlBuy, c);
JPanel pnlUpgrade = new JPanel();
pnlUpgrade.setBackground(Color.yellow); //temp
c.gridx = 2;
c.gridy = 1;
c.gridwidth = 1;
c.gridheight = 1;
c.fill = GridBagConstraints.BOTH;
c.weightx = 0.15;
c.weighty = 0.19;
contentPane.add(pnlUpgrade, c);
JPanel pnlStats = new JPanel();
pnlStats.setBackground(Color.red); //temp
c.gridx = 0;
c.gridy = 2;
c.gridwidth = 1;
c.gridheight = 2;
c.fill = GridBagConstraints.BOTH;
c.weightx = 0.61;
c.weighty = 0.35;
contentPane.add(pnlStats, c);
JPanel pnlSpeed = new JPanel();
pnlSpeed.setBackground(Color.orange); //temp
c.gridx = 1;
c.gridy = 2;
c.gridwidth = 2;
c.gridheight = 1;
c.fill = GridBagConstraints.BOTH;
c.weightx = 0.38;
c.weighty = 0.04;
contentPane.add(pnlSpeed, c);
JPanel pnlRounds = new JPanel();
pnlRounds.setBackground(Color.gray); //temp
c.gridx = 2;
c.gridy = 3;
c.gridwidth = 2;
c.gridheight = 1;
c.fill = GridBagConstraints.BOTH;
c.weightx = 0.38;
c.weighty = 0.31;
contentPane.add(pnlRounds, c);
```
So, what am I doing wrong? Sorry if my English is a bit shitty, and/or the mistake I'm making is blindingly obvious... it's 20 to 5 in the morning, and I've had a long day. Should probably be hitting the hay, fairly shortly.
UPDATE:
It appears that if I change the gridwidth of the brown/gray panel, everything seems to align properly, but I end up with a nasty gap in my layout. Here:
i.imgur.com/6JUx2.png
And the code for the panel (including the amendment suggested by Kevin S):
```
JPanel pnlRounds = new JPanel();
pnlRounds.setBackground(Color.gray); //temp
c.gridx = 1;
c.gridy = 3;
c.gridwidth = 1;
c.gridheight = 1;
c.fill = GridBagConstraints.BOTH;
c.weightx = 0.38;
c.weighty = 0.31;
contentPane.add(pnlRounds, c);
```
So, is there anything that I'm doing wrong, or is this just some weird behaviour of the GridBagLayout that I'm going to have to live with?
Unfortunately, thanks to me editing, I've lost all the embeds that Bala R kindly put in there. So, we're back to the links for images, I'm afraid. And now it seems that I can't post more than two hyperlinks, so the link has been killed in the last one, you need to copy and paste it in.

5,447,169 | 1 | 5,447,261 | null | 3 | 6,612 | Hi im wondering if its possible to add a asp button to the code below, the code below adds an image and text from my database to a dynamic div on my asp page:
```
using System.Data.Odbc;
using System.IO;
public partial class UserProfileWall : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string theUserId = Session["UserID"].ToString();
PopulateWallPosts(theUserId);
}

{

{
cn.Open();

{
//("SELECT wp.WallPostings, p.PicturePath FROM WallPosting wp LEFT JOIN [User] u ON u.UserID = wp.UserID LEFT JOIN Pictures p ON p.UserID = u.UserID WHERE UserID=" + userId + " ORDER BY idWallPosting DESC", cn))
using (OdbcDataReader reader = cmd.ExecuteReader())
{

while (reader.Read())
{

div.Attributes["class"] = "test";
//div.Style["float"] = "left";
div.ID = "test";
Image img = new Image();
img.ImageUrl = String.Format("{0}", reader.GetString(1));
// this line needs to be represented in sql syntax
//img.ImageUrl = "~/userdata/2/uploadedimage/batman-for-facebook.jpg";
img.AlternateText = "Test image";
div.Controls.Add(img);
div.Controls.Add(ParseControl(String.Format("   "+"{0}", reader.GetString(0))));
div.Style["clear"] = "both";
test1.Controls.Add(div);
}
}
}
}
}
protected void Button1_Click(object sender, EventArgs e)
{
string theUserId = Session["UserID"].ToString();
using (OdbcConnection cn = new OdbcConnection("Driver={MySQL ODBC 3.51 Driver}; Server=localhost; Database=gymwebsite2; User=root; Password=commando;"))
{
cn.Open();
using (OdbcCommand cmd = new OdbcCommand("INSERT INTO WallPosting (UserID, Wallpostings) VALUES (" + theUserId + ", '" + TextBox1.Text + "')", cn))
{
cmd.ExecuteNonQuery();
}
}
PopulateWallPosts(theUserId);
}
}
```
Here is the strange thing tho, if I do manage to add a button similar to the way I have added an image, how would I call that button, for example:
I want to call this button "delete" and add code to delete the text in my database related to that div, but if there is multiple divs(there all named the same div id=test) with text and they all have the same asp button how would I be able to tell the button to only delete the current text(in the db) for the current div??
My database stores the information like so:
Im thinking I would have to use idwallposting but not sure how?
Also to give a visual representation of how it looks it may help aid in the understanding:
My css and asp:
```
div#test1 {
}
div .test {
width:90%;
z-index:1;
padding:27.5px;

1. 4 or so sections (eg. friends, person logged in (if they are), etc.)..
2. Keep that toolbar at the bottom, no matter what. The middle content is scrollable. but the header and this footer should always be visible.

5,447,554 | 1 | 5,447,565 | null | 10 | 10,137 | I'm having difficulty getting the GUI layout results I want in an Android app.
A brief description of what I want:
The GUI is to include two TextViews and four Buttons.
The four Buttons are to be laid out horizontally, all in the same row, and fixed at the bottom-right of the screen.
The first of the two TextViews is to start at the top of the screen, with text contents varying from one line to many dozens of lines - more than will fit on the screen without scrolling. So, scrolling is sometimes necessary to see all of the contents. Even when scrolling is necessary, the buttons are not to participate in the scrolling: they are to always remain fixed in a single row at the bottom-right of the screen. When scrolling is necessary, the scrolling text is to always be above the buttons - the buttons are not to overlay the text.
The second of the two TextViews is to appear immediately beneath the first TextView, and will normally only add one or two lines to the total length of text. When scrolling is necessary, the second TextView is to scroll with the first TextView, always appearing immediately beneath the first TextView.
Additional constraints include that I want the layout to look decent on all of the following Android devices, in both vertical and horizontal screen layouts:
- - - - -
I'll worry about tablets another day (like tomorrow).
--
I've tried many different combinations of Layouts, but nothing yet has come very close to the goal.
(With some of the layout combinations I tried, I can fix the buttons at the bottom-left of the screen with RelativeLayout, but everything I try with the scolling text always results with the text scrolling behind the buttons - the buttons overlay the text. I haven't figured out getting the buttons to align to the bottom-right.)
If anyone is up for helping me figure this out, the layout example xml below is a conversation starting point, but it definately fails to achieve the goal result, as demonstrated in the following screen shots, generated using this same layout example xml. (While some of the screen shots demonstrate the same problem, they help to show where I'm at with the different screens.)

Additional Info: When I try to use RelativeLayout, and fix the buttons at the bottom of the screen with `android:layout_alignParentBottom="true"`, then my problem is that I don't know how to fix the bottom of the scroll view with the top of the buttons. Using `android:layout_alignBottom="@id/buttons"` just aligns the bottom of the scroll view with the bottom of the buttons, but then the buttons overlay the text, like this:

Update: The problem of fixing the buttons to the bottom-right, with the scrolling text above the buttons is resolved.
Here's the changed layout XML that works so far (paste more text into text view 1 if you want to see the scrolling):```

I cannot get this to work. After reading articles such as [this](https://stackoverflow.com/questions/5248281/visual-studio-2010-sp1-and-changes-to-the-net-framework) I'm assuming its because the source symbols VS is downloading do not match the version of the framework I have installed. Can someone confirm this?
Secondly, I downloaded the .NET4 source and tried to manually load the pdb's from the module window.
however for all possible selections (3) I get this error:

5,448,702 | 1 | 5,448,843 | null | 29 | 36,833 | I have an issue with deletion in Entity Framework. In short, EF explicitly tries to delete an entity from the database even though I've explcitly configured EF to use cascading deletes in the database.
I have three entity types, `MainEntity`, `EntityTypeA` and `EntityTypeB`. EF has been configured to use cascade deletion when deleting `EntityTypeA` and `EntityTypeB`. In other words, if I delete an instance of `MainEntity`, I want all related `EntityTypeA` and `EntityTypeB` instances to be deleted as well. I never delete `EntityTypeA` or `EntityTypeB` without also deleting their parent.
My problem is that EF explictly issues a `DELETE` statement for `EntityTypeA`, which causes my application to crash.
This is what my model look like:
The relations have the following non-default config:
- `MainEntity -> EntityTypeA OnDelete: Cascade`- `MainEntity -> EntityTypeB OnDelete: Cascade`
The relation `EntityTypeA -> EntityTypeB` has `OnDelete: None`
```
INSERT INTO MainEntities (Name) values ('Test')
insert into EntityTypeA (MainEntityID) VALUES (1)
insert into EntityTypeB (MainEntityID, EntityTypeAId) VALUES (1, 1)
insert into EntityTypeB (MainEntityID, EntityTypeAId) VALUES (1, 1)
```
```
class Program
{
static void Main(string[] args)
{
var context = new Model1Container();
var mainEntity = context.MainEntities.Include("EntityTypeA").SingleOrDefault();
context.DeleteObject(mainEntity);
context.SaveChanges();
}
}
```
When I call SaveChanges, Entity Framework executes the following in the database:
```
exec sp_executesql N'delete [dbo].[EntityTypeA]
where ([Id] = @0)',N'@0 int',@0=1
```
This causes an foreign key violation, because there are items in EntityTypeB's table referencing EntityTypeA instances.
Why does Entity Framework issue an explicit delete for the instance of EntityTypeA even though I've configured Entity Framework to use cascading deletes? If I remove the Include("EntityTypeA") it starts working again.

How do I adjust my outer control, so inner controls do not attempt to draw on top of the rounded corner.
Setting rounded corner on the inner control is not a viable option as it will lead to horrible duplication of corner radius.

5,449,235 | 1 | null | null | 1 | 845 | OK, so there can be 4-6 players which i'd like to place around a circular table (the table is just a background i suppose).
My problem is, since each player can have many cards (up to 10) i'd like that the user will always see himself
at the bottom with his cards opened, and see the rest of the players with hidden cards.
Now, a player can join the table if it has room, i need then to adjust the sits accordingly so if a player clicks
on the top left join button, when he starts playing i need him to see himself at the bottom.
How can i approach this? I suppose placing static views is not the right way.

when the object is near to the camera, everything is perfect.
but if the objects are moved faraway from the camera, the surface of objects would break.

the code snippet of draw objects is:
```
glVertexPointer(3, GL_FLOAT, 32, self.vertices);
glNormalPointer(GL_FLOAT, 32, &(self.vertices[3]));
glTexCoordPointer(2, GL_FLOAT, 32, &(self.vertices[6]));

5,450,255 | 1 | 5,451,212 | null | 1 | 354 | First the sample data:
```
bbbv[1:25] <-1
bbbv[26:50] <-2
bbbw <- 1:25
bbbx <- sample(1:5, 50, replace=TRUE)
bbby <- sample(1:5, 50, replace=TRUE)
bbb <- data.frame(pnum=bbbv, trialnum=bbbw, guess=bbbx, target=bbby)
```
If the target is the same number as the guess then we score 1, else 0.
```
bbb$hit <- ifelse(bbb$guess==bbb$target, 1, 0)
```
This is the problem. I want to calculate four more columns:
```
bbb$hitpone trialnum(n) guess == trial(n+1) target
bbb$hitptwo trialnum(n) guess == trial(n+2) target
bbb$hitmone trialnum(n) guess == trial(n-1) target
bbb$hitmtwo trialnum(n) guess == trial(n-2) target
```
To be clear. For hitmone we look at the trial guess and compare it to the target for the trial before (-1 from the current trial). For hitmtwo we look at the trial guess and compare it to the target 2 back (-2 from the current trial). hitpone and hitptwo are the same but in a positive direction (+1 and +2 from current trial).
And just to be clear, as before we're interested in determining If the target is the same number as the guess then we score 1, else 0 (according to our new calculations).
Now there is some minor difficulty with this task. Each pnum has 25 trials. For hitpone we cannot calculate a +1 for trial 25. For hitptwo we cannot calculate a +2 for trials 25 nor trial 24. The same follows for the hitmone: we cannot calculate -1 for trial 1, nor -2 for trials 1 and 2.
This is how I want the table to look. I have mocked it up by hand, showing the first 1-3 trials and last 23-25 trials.
