4,355,292 | 1 | 4,355,712 | null | 1 | 162 | I'm trying to write a "hello world" for iPhone 4. As this is my first attempt at iPhone app development, and my first experience with Objective C, please feel free to assume you need to teach me how to suck eggs on this one.
As my foundation, I started with the [http://appsamuck.com/day1.html](http://appsamuck.com/day1.html) tutorial - but it's so far out of date I'm not going to get anywhere unless I de-construct the steps.
At this point I'm looking at the part where he tells you how to add a label to the display add the reference to the label.
Unfortunately it just doesn't seem to be fitting together properly.
Essentially, what I'd like the simulator to do when I run the "Built and Run" button is for the "MyLabel" to change to read "HERE"
When this all runs, there are no errors, but cdLabel.text is not changing to read "HERE".
I've got a photo of the basic GUI setup - and can post any other information needed.
the `ViewController.h` reads:
```
@interface MinutesToMidnightViewController : UIViewController {
IBOutlet UILabel *cdLabel;
}
-(void)updateLabel;
```
the `ViewController.m` has the following function in it:
```
-(void)updateLabel {
cdLabel.text = [NSString: "HERE"];
}
```
Finally - there's a photo of how I've set up the GUI bits in the interface designer:
If there's anyone who can connect the dot on this last bit I'd be so very grateful! (Also directions to IOS4 beginner's tutorials or open source APPS would be highly valued :)
Thanks!
- A
In response to the question of when do I call `updateLabel`
I have the function
```
- (void)applicationDidFinishLaunching:(UIApplication *)application {
[viewController updateLabel];
}
```
built into my `MinutesToMidnightAppDelegate.m` file

As soon as I move the TableView scroll up or down, the problem immediately resolves itself. Also, if I quit the app and go back in, the header is displayed correctly.
I have drawn a red box around the problem area.
Anyone ever see this behavior before?
Notice the difference in how the header is displayed below. This is how it SHOULD look from the start. All I do between screenshot 1 (above) and screenshot 2 (below) is scroll the UITableView.

4,355,459 | 1 | 4,448,151 | null | 0 | 2,361 | I have a Telerik grid in my asp.net mvc application that looks something like:
Now it lists all the regions in a zone selected from the list placed just above the grid. zoneid is foreign key in the grid. Now I want that when I add new region in the grid the zoneID should be taken from the list instead of what is present in zone column of the grid because that value is just to display the zone and that can also be removed from the grid as it as apparent from the list which zone the listed regions belong to.
I understand that I could have used editor templates to show this list inside the grid on edit but I prefer it to be outside the grid and provide some filtering on basis of the zone as we are likely to have many regions per zone. so my concern here, now, is how can I set ZoneID of a region (edited or newly added) equal to selected value of list that shows just above the grid control.

4,355,525 | 1 | 4,356,080 | null | 6 | 14,414 | I am trying to write a blur shader for the iPad. I have it working but I am not very happy with the results. I get very choppy frame rates and the blur looks like crap when blur amount is high.
Any ideas on how to improve things?
Some sample output:
```
uniform sampler2D texture;
varying mediump vec2 fragTexCoord;
varying mediump vec3 eyespaceNormal;
varying highp float blurAmount;
void main(void)
{
highp vec2 gaussFilter[7];
gaussFilter[0] = vec2(-3.0, 0.015625);
gaussFilter[1] = vec2(-2.0, 0.09375);
gaussFilter[2] = vec2(-1.0, 0.234375);
gaussFilter[3] = vec2(0.0, 0.3125);
gaussFilter[4] = vec2(1.0, 0.234375);
gaussFilter[5] = vec2(2.0, 0.09375);
gaussFilter[6] = vec2(3.0, 0.015625);
highp float blurSize = blurAmount * 1.0;
/////////////////////////////////////////////////
// 7x1 gaussian blur fragment shader
/////////////////////////////////////////////////
highp vec4 color = vec4(0,0,0,1);
for( int i = 0; i < 7; i++ )
{
color += texture2D( texture, vec2( fragTexCoord.x+gaussFilter[i].x*blurSize, fragTexCoord.y+gaussFilter[i].x*blurSize ) )*gaussFilter[i].y;
}
gl_FragColor = color;
}
```
Edit:
A box blur may be the way to go.
Here is a box blur version of the shader:
```
highp vec4 color = vec4(0,0,0,1);
color += texture2D(texture, vec2(fragTexCoord.x, fragTexCoord.y - 4.0*blurAmount)) * 0.05;
color += texture2D(texture, vec2(fragTexCoord.x, fragTexCoord.y - 3.0*blurAmount)) * 0.09;
color += texture2D(texture, vec2(fragTexCoord.x, fragTexCoord.y - 2.0*blurAmount)) * 0.12;
color += texture2D(texture, vec2(fragTexCoord.x, fragTexCoord.y - blurAmount)) * 0.15;
color += texture2D(texture, vec2(fragTexCoord.x, fragTexCoord.y)) * 0.16;
color += texture2D(texture, vec2(fragTexCoord.x, fragTexCoord.y + blurAmount)) * 0.15;
color += texture2D(texture, vec2(fragTexCoord.x, fragTexCoord.y + 2.0*blurAmount)) * 0.12;
color += texture2D(texture, vec2(fragTexCoord.x, fragTexCoord.y + 3.0*blurAmount)) * 0.09;
color += texture2D(texture, vec2(fragTexCoord.x, fragTexCoord.y + 4.0*blurAmount)) * 0.05;
gl_FragColor = color;
```

Hi i was wondering if there was a way for a batch file to make a pop up appear using the `msg * "hi"` command along with other selections besides the ones that are there by default (cancel and ok) by this, i mean add custom buttons to the pop up message such as a "next" button that would bring you to another pop up message with dialog on it or something along those lines. In summary , is there a way to edit the results of the `msg * "text goes here"` command?
This is what comes up...
And this is kind of what i want:
However , i also would like to know if its possible to change the title of the pop up message and the size or position of it. I know that this is starting to sound like a gui based popup in a batch file but im just wondering if its possible by any means neccessary (Keep in mind that i only want to use batch/shell). Any information or ideas would really help! Thanks!

You can try it yourself by pasting the embed code in to Rap Genius with firebug. You'll see this:
I need a way to detect whether a video is specifically blocked from Rap Genius.
Note that this is different from checking whether a video cannot be embedded – i.e., if you GET `http://gdata.youtube.com/feeds/api/videos?v=2&alt=jsonc&q=_kmeFXjjGfk`, you'll see that in the JSON response, `data.items[0].accessControl.embed == 'allowed'`
One clue: before the video starts playing, the player makes a request to a URL that looks like this:
```
http://www.youtube.com/get_video_info?video_id=_kmeFXjjGfk&el=embedded&ps=default&eurl=http%3A%2F%2Frapgenius%2Ecom&hl=en_US

Which, when curled, gives this response:

4,358,582 | 1 | 4,360,516 | null | 14 | 14,100 | The Google Map I have is only beeing rendered partially and is centered to the wrong point (it should center to the marker). See below:
Now to add a little more detail:
- - -
Especially the last point is the one I'm wondering most about. I guess opening the developer console re-executes some JavaScript.
So: Can I call a function to re-execute JavaScript, the way the developer console does?
This is the code:
```
<script type="text/javascript">
{literal}
function initialize() {
if (GBrowserIsCompatible()) {
var map = new GMap2(document.getElementById("map")); //, { size : {width:600,height:600} }
map.addControl(new GLargeMapControl3D());
map.addControl(new GMapTypeControl());
map.addControl(new GScaleControl());
map.setCenter(new GLatLng(51.17689812200107, 9.84375), 5);
map.checkResize();
var geocoder = new GClientGeocoder();
function showPoint(lat, lon) {
if (lat != "" && lon != "") {
var point = new GLatLng(lat, lon);
map.setCenter(point, 10);
var marker = new GMarker(point, {draggable: true});
GEvent.addListener(marker, "dragstart", function() {
// map.closeInfoWindow();
});
GEvent.addListener(marker, "dragend", function() {
var newPoint = marker.getLatLng();
$('#lat').val(newPoint.lat());
$('#lon').val(newPoint.lng());
// marker.openInfoWindowHtml("Neue Koordinaten Lat: "+ newPoint.lat() +" Lon: "+ newPoint.lng());
});
map.addOverlay(marker);
}
}
{/literal}showPoint("{$gmap_lat}", "{$gmap_lon}");{literal}
}
}
{/literal}
```
This is where I put the div:
```
<fieldset style="-moz-border-radius: 1em; -webkit-border-radius: 1em;">
<legend>Karte</legend>
<div id="map" title="Lage von '{$name}'"><br>Die Karte wird geladen...<br><br>Hinweis: Damit dies funktioniert müssen Sie in Ihrem Browser JavaScript aktivieren</div>
Falls sich der Marker nicht auf der richtigen Position befinden sollte, bewegen Sie diesen mit Ihrer Maus auf die richtige Position.
<br>Länge: <input type="text" id="lat" name="lat" value="{$gmap_lat}">
Breite: <input type="text" id="lon" name="lon" value="{$gmap_lon}">
</fieldset>
```
And on the div the following CSS rules apply:

Using two images: one as mask (the diagonal lines) and the other the image and text themselves (the mask and image+text are the same size):
 
..and I just can't get it done!
I've tried all combinations with divs and z-indeces, opacity and background-image.. (should mention I'm noob to html).
Here's one shot I got at it (with only the mask and an image):
```
div {
position: absolute;
top: 775px;
left: 0px;
height: 188px;
width: 272px;
background-image: url('grey-out.png');
}
img {
z-index: 1000;
}
```
---
```
<div></div>
<img src="41_large.png" />
```
Which just gives the diagonal lines themselves..
Can someone please help me out?

4,359,597 | 1 | 4,359,647 | null | 4 | 3,256 | i know Visual Studio has no way to increment the build number in a way that people would expect, but it support [randomizing the build number](https://stackoverflow.com/questions/826777/how-to-have-an-auto-incrementing-version-number-visual-studio):
My `AssemblyInfo.cs` file contains:
```
// Version information for an assembly consists of the following four values:
//
// Major Version
// Minor Version
// Build Number
// Revision
//
// You can specify all the values or you can default the Build and Revision Numbers
// by using the '*' as shown below:
// [assembly: AssemblyVersion("1.0.*")]
[assembly: AssemblyVersion("1.0.*")]
[assembly: AssemblyFileVersion("1.0.*")]
```
And yet it gives, what appears to me, non-sensical results (even allowing for Visual Studio's pseudo-random version numbers):
So the simpler question is:
> What do i put into `AssemblyInfo.cs` to make it work?
From [MSDN](http://msdn.microsoft.com/en-us/library/system.reflection.assemblyversionattribute.aspx) (reformatted for clarity):
> You can specify all the values or you
can accept the default build number,
revision number, or both by using an
asterisk (*). For example, ```
[assembly:AssemblyVersion("2.3.25.1")]
```
indicates 2 as the major version, 3 as
the minor version, 25 as the build
number, and 1 as the revision number.
A version number such as ```
[assembly:AssemblyVersion("1.2.*")]
```
specifies 1 as the major version, 2 as
the minor version, and accepts the
default build and revision numbers. A
version number such as ```
[assembly:AssemblyVersion("1.2.15.*")]
```
specifies 1 as the major version, 2 as
the minor version, 15 as the build
number, and accepts the default
revision number. The default build number increments
daily. The default revision number
is random.
i take that to mean that version numbers are:
```
[1.0.0.0]
major.minor.build.revision
```
while
```
[1.0.0.*]
major.minor.build.[random]
```
and

4,361,023 | 1 | 4,371,643 | null | 6 | 8,332 | I have particles that I want to be able to change the color of in code, so any color can be used. So I have only one texture that basically has luminance.
I've been using `glColor4f(1f, 0f, 0f, 1f);` to apply the color.
Every blendfunc I've tried that has come close to working ends up like the last picture below. I still want to preserve luminance, like in the middle picture. (This is like the Overlay or Soft Light filters in Photoshop, if the color layer was on top of the texture layer.)
Any ideas for how to do this without programmable shaders? Also, since these are particles, I don't want a black box behind it, I want it to add onto the scene.

I'm currently in the progress of understandig the maths behind this, and there's something I dont onderstand. As far as I'm concerned, the DFT has a complexity of `O(N*N)`. If I look at the following algorithm:
I don't understand how it works. Are we going to do this caluculation for every pixel in the tranformed ?
1. We have an image of 2*2.
2. For each pixel in this image we're going to do the DFT F(x,y)
3. I'll create a new image, and each pixel is the magnitude of the corrosponding complex value
Is this how it works or am I missing something? Because the way I see it now, it has a complexity of `O(N^4)`

4,361,654 | 1 | null | null | 0 | 347 | I'm using [jQuery Form plugin](http://jquery.malsup.com/form/) to create a very simple contact form. However, there seems to be some conflict (?) between it and the PHP script I'm using as well.
The call is super simple, like so:
```
$('.contactform').ajaxForm({
target: '#error',
beforeSubmit: function() {
$('#error span').remove();
$('#error').append('<p class="loading">Sending your message...</p>');
},
success: function() {
$('#error p.loading').fadeOut();
$('#error').fadeIn('slow');
}
});
```
it takes the POST method from the form by default. What happens is, the script is stuck on "sending your message", even though the PHP script is successful, gives a response and sends the message correctly. I checked in Firebug, and it seems like there's an 404 error for the PHP script, but the response is correct (see the image)
I would love some help debugging the problem - the PHP script that's supposedly cannot be found can be viewed here: [http://pastie.org/1350597](http://pastie.org/1350597)

4,361,659 | 1 | null | null | 1 | 985 | I'm developing polish blogosphere monitoring website and I'm looking for "best practice" with handling
massive content download in python.
Here is sample sheme of a workflow:
Description:
I've categorized database of rss feeds (around 1000). Every hour or so I should check feeds if there are some new items posted. If so, I should analyze each new item.
Analyze process handles metadata of each document and also downloads every image found inside.
Simplified one-thread version of a code:
```
for url, etag, l_mod in rss_urls:
rss_feed = process_rss(url, etag, l_mod) # Read url with last etag, l_mod values
if not rss:
continue
for new_item in rss_feed: # Iterate via *new* items in feed
element = fetch_content(new_item) # Direct https request, download HTML source
if not element:
continue
images = extract_images(element)
goodImages = []
for img in images:
if img_qualify(img): # Download and analyze image if it could be used as a thumbnail
goodImages.append(img)
```
So I iterate throught the rss feeds, downloads only feeds with new items. Download each item from a feed. Download and analyze each image in item.
HTTR requests appears at the follwing stages:
- downloading rss xml document
- downloading x items found on rss
- downloading all images of each item
I've decided to try python gevent (www.gevent.org) library to handle multiple urls content download
What I want to gain as a result:
- Ability to limit number of external http requests
- Ability to parralel downloading all listed content items.
What is a best way to do it?
I'm not sure, because I'm new to parralel programming at all (well this async request probably has nothing to do with parralel programming at all) and I have no idea how such tasks
are done in a mature world, yet.
The only idea come to my mind is to use the following technique:
- Run processing script via cronjob every 45 minutes
- Try to lock file with written pid process inside at the very beggining. If locking failed, check process list for this pid. If pid not found, probably process failed at some point and its safe to srart new one.
- Via the wrapper for gevent pool run task for rss feeds download, at every stage (new items found) add new job to quique to download item, at every item downloaded add tasks for image downloading.
- Check every some seconds state of jobs currenly running, run new job from quique if there free slots available in FIFO mode.
Sound OK for me, however maybe this kind of task has some "best practise" and I'm reinventing the wheel now.
Thats why I'm posting my question here.
Thx!

Now, given a set of points, in the example S = (A, B, C, D, E, F) and n = 6 (the fact points are actually endpoints of segments is negligible), is there an algorithm that has complexity better than O(n^2) in the average case to find a partition of the set (the representative element of the subsets is unimportant)?
Attempts to find theoretical definitions of this problem were unsuccessful so far: k-means clustering, nearest neighbor search and others seems to me different problems. The picture shows what I need to do in my application.
Any hint? Thanks
: while the actual problem (cluster near points given some kind of invariant) should be solvable in better better than O(n^2) in the average case, there's a serious flaw in my problem definition: =~ is a equivalence relation because of the simple fact it doesn't respect the . I think this is the main reason this problem is not easy to solve and need advanced techiques. Will post very soon my actual solution: should work when near points all satisfy the =~ as defined. Can fail when poles apart points doesn't respect the relation but they are in relation with the center of gravity of clustered points. It works well with my input data space, may not with yours.

Initially I have user input decimal numbers (0 - 15), and I will turn that into binary numbers.
Say these numbers are written into a text file, as shown in the picture. These numbers are arranged by the numbers of 1's. The dash - is used to separate different groups of 1.
I have to read this file, and compare strings of one group with the all the strings in the group below, i.e., Group 1 with all the strings in group 2, and group 2 - group 3.
The deal is that, only one column of 0 / 1 difference is allowed, and that column is replaced by letter t. If more than one column of difference is encountered, write none.
So say group 2, 0001 with group 3, 0011, only the second column is different. however, 0010 and 0101 are two columns of difference.
The result will be written into another file.....
At the moment, when I am reading these strings, I am using vector . I came across bitset. What is important is that I have to access the character one at a time, meaning I have break the vector into vector . But it seems like there could be easier way to do it.
I even thought about a hash table - linked-list. Having group 1 assigned to H[0]. Each comparison is done as H[current-group] with H[current_group+1]. But beyond the first comparison (comparing 1's and 0's), the comparison beyond that will not work under this hash-linked way. So I gave up on that.
```
#include <iostream>
#include <fstream>
#include <vector>
#include <string>
#include <algorithm>
#include <iterator>
using namespace std;
int main() {
ifstream inFile("a.txt");
vector<string> svec;
copy(istream_iterator<string>(inFile), istream_iterator<string>(), back_inserter(svec));
copy(svec.begin(), svec.end(), ostream_iterator<string>(cout,"\n"));
for(int i = 0; i < svec.size(); i++)
{
cout << svec[i] << " ";
}
inFile.close();
return 0;
}
```
This is the sample code of writing it into a file....but like I said, the whole deal of vector seems impractical in my case....
Any help is appreciated. thanks

Now what I want to do is, when a person selects a value in UC3 the properties for player1 need to be set. When a value gets selected in UC4 I need the properties for player2 to be set. I was thinking to do this with properties but when searching for Properties and WPF I stumbled upon Dependency Properties. Which started to confuse me a bit, would I need to use normal Properties or these Dependency Properties.
- How can I know if I have to set the player1 values or the player2 values (this depends from which UserControl sends the data)?- How would I save these values best for the entire application?- Is putting the User Controls on hidden at the start (due to positioning) the best way or is there a better alternative?

self.tableView.contentInset = UIEdgeInsetsMake(60.0f, 0.0f, 0.0f, 0.0f);

}
```
Problem is if I start to scroll whilst the content inset is "visible" (i.e. during reload) I get this weird behaviour where my table sections do not scroll all the way to the top - see screenshot for a clear visual of what I am trying to describe here.
Has anyone experienced this before? Any ideas on what I should be looking at to try and fix it?
Many thanks in advance,

4,365,856 | 1 | 4,420,108 | null | 4 | 4,289 | I asked a similar question already which got me to where I am now but I really need some help on this one. Its the last thing in my way to completing something cool (in my eyes lol)
I have a 3d world where I can move around and in this world are simple cubes.
Using the function -(CGPoint)getScreenCoorOfPoint:(IMPoint3D)_point3D I can work out where these cubes are in X,Y within the 3D world. But its not based on where I am but where they are with the 3d Area. Using the same function, I can also work out where I am. Also I can find out where someone has tapped on the screen.
How on earth do I map these together so that I can work out if I have clicked one of them?
Surely I need something to work out which way I am facing. People have suggested rendering them off screen and doing something but it went completely over my head. I think of scrapping the function about and building my own based on the 3d coords (somehow)
Code
```
for (NSDictionary *item in self.players)
{
int x;
int z;
x = [[item objectForKey:@"posX"] floatValue];
z = [[item objectForKey:@"posZ"] floatValue];
IMPoint3D playerPos;
playerPos.x = x;
playerPos.z = z;
playerPos.y = 1;
CGPoint screenPositionOfThisCube ;
screenPositionOfThisCube = [self getScreenCoorOfPoint:playerPos];
#define TUNE 28
CGRect fingerSquish = CGRectMake(
screenPositionOfThisCube.x - TUNE,
screenPositionOfThisCube.y - TUNE,
TUNE * 2,
TUNE * 2);
// now check that the POINT OF THE TOUCH
// is inside the rect fingerSquish
if ( CGRectContainsPoint( fingerSquish, pos ) )
{
NSLog(@"WOOP");
// YOU HAVE FOUND THE TOUCHED CUBEY.
// YOU ARE DONE. this item is the cube being touched.
// make the cube change color or something to test it.

4,366,119 | 1 | 4,370,253 | null | 8 | 2,629 | OK, I have this problem to solve but I can’t program it in Java correctly. See the picture below, you’ll see a 6 pointed star were every point and intersection of lines is a letter.
The assignment is to position the numbers 1 to 12 in such a way that the sum of all lines of four balls is 26 and the sum of all the 6 points of the star is 26 as well.
This comes down to:
- - - - - - -
So I started programming a program that would loop through all options brute forcing a solution. The loop is working, however, it now shows solutions where one number is used more than once, which is not allowed.

```
if ((A!= B != C != D != E != F != G != H != I != J != K != L)
```
I tried the above, but it doesn't work, because it says:
> incomparable types: boolean and int.
(instead of making a nested 12*12 statement which checks every variable combination)

```

4,368,894 | 1 | null | null | 0 | 478 | In the query below there is a field called `main` which is used to differentiate the categories.
So, there are common categories and main categories and both can be found on a tree. The `main` field is just a type and there's nothing with the tree structure, I mean, it's like a status field.
```
SELECT `c`.*,
(count(p.id)-1) AS `depth`
FROM `categories` AS `c`
CROSS JOIN `categories` AS `p`
WHERE (c.lft BETWEEN p.lft AND p.rht)
AND (c.root_id =p.root_id)
AND (p.main =1)
GROUP BY `c`.`id`
ORDER BY `c`.`root_id` ASC, `c`.`lft` ASC
```
There is a `where` clausule which specify that the parent category need to be a main category. Also, sometimes I need to do a `select` where the parent category is a common category `p.main =0`.
The `depth` is the position of the element in the tree. So if a category is a one level children of another, the depth will be `1`, if two levels, the depth will be `2`.
My problem is that when I do the select above, if there are children marked as common category on a tree where the father is a main category (selecting `p.main =1`) the common categories `depth` is always `0`.
In other words, the select works properly, if I select all categories that has the top parent marked as `main`, it will display the tree with all categories including children categories marked with `main=0`. But in this case, the depth is always `0`
See the results:
The category `1423` is a child of `27` and is not a main category, but `27` is, so depth is `0`, but need to be `1`. The category `276` is a child of `64` and both are a main categories, so it has the right depth.
How can I change this query so that the `depth` field work as expected?

4,369,689 | 1 | 4,374,711 | null | 4 | 698 | I have a jQuery `mouseup` event set on the background element that is blue with dotted lines (thats a background image, not elements). It only fires if one of the other elements is not laid on top. I could relay the event in code, but that seems to invite chaos. Is there a way to get the blue element to receive the `mouseup` event even if another element is resting on top?
Also, currently , the red, blue, and black overlay elements are not children of the blue background element, but they could be, if need be.
## Edit:::::
Refactoring the html to nest the elements in to a parent-child relationship worked.

text-aligning all not giving me the result I want.

I've looked through some resources and managed to get working city search with spelling correction. It basically searches for exact matches, if none are found, it searches for double metaphone matches and limits them by the (levenshtein/length)<0.5 .
I'd like to implement a way to parse states (and if possible neighborhoods).
My question is:
Is there a way for MySQL to search for the city (and state)? What I mean is, is there a way for me to split the string and pass the parts to MySQL without knowing what each part is? (what part is city and which is state)
I'm thinking about this because I'd like to have spelling correction/guessing instead of just looking through the string with an array of correctly spelled states - similar to the way I have it with the cities.
There is probably an easy way to do this, I'm just mentally fatigued from getting the current city search working. I'd appreciate any help on this. Thanks.

Thank you for all answers. I'm still slightly confused as there's no agreement on whether or not this code comply with C++ standards. Will ask another question to dispel my doubts

4,372,259 | 1 | null | null | 2 | 1,466 | I have been using the Hough transform in my application both using Matlab and OpenCV/labview and found that for some images, the hough transform gave an obviously wrong line fit (consistently)
Here are the test and overlayed images. The angle seem right, but the rho is off.
On the image below, you will see the top image tries to fit a line to the left side of the original image and the bottom image fits a line to the right side of the image.
In Matlab, I call the Hough function through
```
[H1D,theta1D,rho1D] = hough(img_1D_dilate,'ThetaResolution',0.2);
```
in C++, i trimmed the OpenCV HoughLines function so I end up with only the part we are filling the accumulator. Note that because my theta resolution is 0.2, I have 900 angles to analyze. The tabSin and tabCos are defined prior to the function so that they are just a sin and cos of the angle.
Note that these routines generally work well, but just for specific cases it performs the way I have shown.
```
double start_angle = 60.0;
double end_angle = 120.0;
double num_theta = 180;
int start_ang = num_theta * start_angle/180;
int end_ang = num_theta * end_angle/180;
int i,j,n,index;
for (i = 0;i<numrows;i++)
{
for (j = 0;j<numcols;j++)
{
if (img[i*numcols + j] == 100)
{
for (n = 0;n<180;n++)
{
index = cvRound((j*tabCos[n] + i * tabSin[n])) + (numrho-1)/2;
accum[(n+1) * (numrho+2) + index+1]++;
}
}
}
}
```
TabCos and tabSin are defined in Labview with this code
int32 i;
float64 theta_prec;
float64 tabSin[180];
float64 tabCos[180];
theta_prec = 1/180*3.14159;
for (i = 0;i<180;i++)
{
tabSin[i] = sin(itheta_prec);
}

4,372,873 | 1 | 4,374,927 | null | 1 | 19,458 | Ok so ive been finishing off my batch program called "stringparsing.bat" and the last error im having trouble with is one that says "missing operator" when i use the following snippet:
```
set /p linecount=

set foo=0
set linenumber=0
:lineset
set /a linenumber=%linenumber% +1
set /p line1= %linenumber%
echo %line1% >> %name%.txt
set /a foo=%foo%+1
set /a line number=%linenumber%+1
IF %foo%==%linecount% goto MAIN123
goto lineset
```
More specificly, ive narrowed it down to :
```
set /a linenumber=%linenumber% +1
set /p line1= %linenumber%
```
Im pretty sure im mis-using the command... what i am trying to do, is make a prompt that asks the user to input how many lines of text that they are going to insert into a text file. Then make a loop that asks the user to type some text which is then sent to the text file. But i wanted to to put the line number before the prompt so that it would look like this:
So when the batch file asks for the first line, it says 1: , and when it asks for the second line, its says 2: , and so on. after each line prompt, i get the "missing operator" error message... Btw i need to use this scirpt to get it to work:
set /p line1= %linenumber%+1
But in order to use this command with the at the end, do i have to add the parameter as well as the parameter?
Any ideas?

4,373,360 | 1 | 4,375,280 | null | 4 | 3,053 | Greetings all,
As seen in the image,
I have an object named O (set of linestripes).Its object-coordinate system is (x',y',z').
I translate,rotate this object in my OpenGL scene using following code snippet:
```
glPushMatrix();
glTranslatef(Oz, Oy,Oz);
glRotatef(rotationX , 1.0, 0.0, 0.0);
glRotatef(rotationY, 0.0, 1.0, 0.0);
glRotatef(rotationZ, 0.0, 0.0, 1.0);
contour->render();
glPopMatrix()
```
;
I have a point called H ,which is translated to (hx,hy,hz) world coordinates using
```
glPushMatrix();
glTranslatef(hx,hy,hz);
glPopMatrix();
```
If I am correct, (Oz,Oy,Oz) and (hx,hy,hz) are world coordinates.
Now,what I want todo is calculate the position of H (hx,hy,hz) relative to O's object-coordinate system.(x',y',z');
As I understood,I can do this by calculating inverse transformations of object O and apply them to point H.
Any tips on this? Does OpenGL gives any functions for inverse-matrix calculation ? If I somehow found inverse-matrices what the order of multiplying them ?
Note : I want to implement "hammer" like tool where at point H ,I draw a sphere with radius R.User can use this sphere to chop the object O like a hammer.I have implemented this in 2D ,so I can use the same algorithm if I can calculate the hammer position
relative to (x',y',z')
Thanks in advance.

I would like the ability to select different layouts in the admin when creating and updating Pages. What I envisioned is a drop down on the Pages form that allowed me to select a layout/template.
The only thing I know about layouts is you are required to add them to /views/layouts/ and specify the layout at the top of the controller. I need a way to manage layouts on a per Page basis inside the app itself.
Is that even possible? If so, can you explain on a high level how that might be done so I can have a starting point?

4,373,528 | 1 | 4,394,333 | null | 0 | 328 | I am pulling my hair out on this one. I have a NavigationController with two levels of TableViews. Each TableView is in its own NIB file. The first level simply displays a list. Upon selecting a cell, it takes the user to a second level TableView with a more detailed list. It is on this second level TableView that I want to display a search bar (actually I am using a SearchDisplayController as well). I have added it to the TableView because I want the SearchBar to scroll with the table.
Below, I am displaying two screenshots. The first is the second level tableview in InterfaceBuidler. The second is the second level tableview at runtime. For some reason, the SearchBar doesn't display at runtime.
I have tried creating a completely new project from scratch and the same things happens. I don't understand why the SearchBar doesn't display on a NIB pushed on the NavigationController.
Before you ask, if I put the SearchBar on the first level TableView, it shows up just fine. Yes, I am adding it to the TableView itself, so it is a part of the view that should be displayed.
Help! What am I doing wrong?
This is what actually displays after the XIB is pushed...

4,373,666 | 1 | 4,388,829 | null | 4 | 3,865 | I'm trying to write a little greasemonkey script/bookmarklet/what have you for Google Docs. The functionality I'd like to add needs a keypress/keyup/keydown event handler (one of those three). Unfortunately, Javascript isn't my forté, and I can't seem to capture (?) a keypress event to while in the edit pane. As a last resort, I've tried the following:
```
javascript:(function(){
els = document.getElementsByTagName("*");
for(i=0;i<els.length;i++){
els[i].onkeypress=function(){alert("hello!");};
els[i].onkeyup=function(){alert("hello2!");};
els[i].onkeydown=function(){alert("hello3!");};
}
})();
```
However, this still doesn't capture keypresses in the editing pane - no annoying alerts (although it seems to work for most other sites...). I've checked in Chrome and Firefox both (I can't get it to work in either one).
I tried "Log Events" in Firebug (and checked out all the registered events via a neat little extension to Firebug, Eventbug); it didn't seem like those events were firing on keypresses.
Edit:
To clarify [Tim], I made this [screenshot](http://cl.ly/07413k1F3R3X1G0b3n0Y) with some annotations...
The "editing pane" I'm talking about seems to be a bunch of Javascripted-up divs displaying what I type.
Any ideas? Thanks!

After some google search I find it!
This algorithm is a non-tail recursive method.
The reversed input string is completely pushed into a stack.
```
prefixToInfix(stack)
1) IF stack is not empty
a. Temp -->pop the stack
b. IF temp is a operator
i. Write a opening parenthesis to output
ii. prefixToInfix(stack)
iii. Write temp to output
iv. prefixToInfix(stack)
v. Write a closing parenthesis to output
c. ELSE IF temp is a space -->prefixToInfix(stack)
d. ELSE
i. Write temp to output
ii. IF stack.top NOT EQUAL to space -->prefixToInfix(stack)
```
when the Stack top is
> F(ABC)
and we enter the algorithm, "A" is written to the output as it was currently the value of
> temp=A (say)
Now how I get '' on the output column as according to the algorithm the next temp value will be "B" which was popped from the stack after the last recursive call.
How the diagram is showing output "((A-" ...
Where I am doing the incorrect assumption ?
Could someone take the trouble in explaining it ?

tableView.bounces=FALSE;
```
When I used searchbar, that time bounces also, won't work.
The output like as follows:
1. I need to change background color, when I searching content.
2. I need: tableView.bounces=FALSE;
will work, when I searching content.
