Subscribing to Web Application Events from WCF
|
I have a simple web application that allows users to upload a file to the server and store the data in the Database.
There will be a decoupled service (probably WCF) which needs to act upon the data, but i am not sure what the best mechanism is to alert the service? Is it a good idea for the WCF service to poll the database every few minutes to check for new data? Or should i be looking at other patterns (?) to better accomplish this task? using Events perhaps?
I have not done anything like this before so looking for some guidance to start off with.
Thanks

XSD.exe doesn't enforce minOccurs
|
I have a simple schema where I'm declaring both minOccurs and maxOccurs to 1. When I run the XSD.exe to generate a C# class and consume the class in code; the field is not enforced as mandatory. Is there some additional step missing? or does the classes generated using XSD.exe don't mandatory fields?
any suggestions or insight will be helpful.

Tip to analyze and write simple or complex sql queries ?
|
I just want to know the ways you guys use while writing a complex queries depending upon the scenario. Any tool or instant logic or paper pen. I am asking so as Sql do not provide as much as flexibility (like API, Debuggers etc) than Visual Studio, where we can debug and fix code instantly. I has posted numerous questions here on SO regarding SQL and got the answer in a minute or two.
I am not that much good in Sql programming, as I feel more comfortable in the C# or VB.net. But i am working on that part too. So, How Do I improve my programming skill in SQL query writing, apart from studying books.
Please guide...

masking hostname to IP address lookup in Linux/Bash/Perl
|
Many of the servers in our environment have their loop-back line in **`/etc/hosts`** configured like so:
127.0.0.1 mydevserver.testdomain.com mydevserver localhost.localdomain localhost
Normally, this is not an issue. However, we are now dealing with some external software from a vendor that calls gethostbyaddr and their installer is designed to fail if the result of **`hostname --ip-address`** is 127.0.0.1. This of course causes it to fail on our systems because the servers hostname is in the loopback line of `/etc/hosts`.
My question is, if I wrap the installer in a bash or perl script, is there a way to "mask" or temporarily alter the results of **`hostname --ip-address`** without changing the /etc/hosts file?

What book can we use to learn c#, when we know java?
|
i want to learn about c#. I have read java and It's jvm languages like groovy. Now i have to move to c# (as a matter of my college course), as i have mentioned i know java, and i knew what is object, method's or functions , and so on OOP. Now my question is what book i can prefer? I have went on amazon.com review's, and came to know two books, c# 4.0 in a nutshell and c# in depth. Now my doubt is whether i can read c# in depth book, as i guess it need's some basics of c# version 1. Since some says c# have It's roots in java (a little bit), can i go with reading c# in depth book? Or c# in a nutshell or any other book's. Correct me if am wrong.

Things to consider while implementing an original website architecture
|
Things you should know know about my disposition -
1. My **First Time** building a "big" site.
2. Working on **PHP**
3. Have **no idea about how scalable** the site can be and all that jazz.
4. **Willing to use a framework** if it gives me a **LOT of flexibility** in architecture while still providing me the advantages like **security, performance** etc.
The main question being -
*Suppose you were in my place and wanted to implement your original architecture, what are the things you'd be careful about?
How will you go about implementing security? Anyway you can import and integrate third party security modules into your website?*
I know i'm making flaws... just wanting to know what they are primarily..solving them will come next. Thank you :].

my definition of thread-safety for stackoverflow tag wiki
|
Wikipedia has the following definition:
> Thread safety is a computer programming concept applicable in the
> context of multi-threaded programs. A piece of code is thread-safe if
> it only manipulates shared data structures in a manner that guarantees
> safe execution by multiple threads at the same time. There are various strategies for making thread-safe data structures.[1][2] ... and so on ( http://en.wikipedia.org/wiki/Thread-safety )
Great! Code is thread-safe if it operates in thread-safe manner! It's a very, very informative definition!
My proposition -- specifically for stackoverflow tag wiki -- is the following:
**Basically, thread-safety means that program's observable behavior does not depend on eligible thread scheduling order.**
Still, it is a very basic definition. Say, threads may log messages into log file, and reodering of log messages may be OK. So program observable behavior may vary, but the program may be considered thread-safe.
Probably, we need to specify allowed types of different program observable behaviors while being thread-safe. Yet another complication: there may be thread-safe (or thread-unsafe) code, not the whole program.
Note, that tag wiki definition is limited in size. So it may be possible that my concise definition is OK, despite its minor imprecision.
So, the question is: how to precisely define thread-safety for tag wiki?

Javascript Move Help

I am currently making javascript where when I use the w,a,s,d keys it move a block left, right, up, and down. It also only lets you move the div within a bigger div. What I want to do is be able to add more blocks but the block you are moving wont be able to move through the block, you will have to move around it.

XCode 4.2 Beta and iOS 4.2
|
I am having a problem with developing a new project using XCode 4.2 (the beta) and deploying this onto an iPod touch running ios 4.2.1. I told xcode that the built target was ios 4.2, but it does not seem to want to run on it at all. The project builds successfully, but then never actually runs on the iPod.
However, it does work fine if I am using an iPod Touch that has iOS 4.3 on it. Does anyone know how I could fix this or what the problem may be. I was wondering if there was an easy way that did not involve me pretty much redoing everything in an older version of xcode with the older SDK's installed.
Thanks in advance for your help!

How can I update a link description cached in Facebook?

I posted links to slideshare on my facebook fanpage but have since updated the slideshow and the link information, however the old cached link description still appears on the fanpage and is repeated when the link is shared.

how to replace specific letters in a list with other letters
|
I have a feeling there's a very easy answer to this question but ive been thinking about it for days and can't figure it out. its kind of an encryption program im writing for fun to use with my friends.
I have a list that looks like this:
foo = ["z", "q", "t", "a", "p", "m", "n", "b", "c", "w", "l", "d", "f", "h",
"y", "e", "j", "k", "g", "i", "o", "r", "u", "s", "v", "x"]
and i have another list that looks like this:
bar = ["h", "e", "l", "l", "o", "m", "y", "n", "a", "m", "e", "i", "s", "r",
"e", "a", "l", "l", "y", "l", "o", "n", "g", "a", "n", "d"]
what i want to do is use the first element of foo, and replace the first element of bar with it, and so that the first element of foo is now always worth "h", so if "h" ever comes up in bar again, "z" (the first element of foo) is automatically put in. the second element of foo is then subbed in for the second element of bar (unless it's "h") and then second element then becomes "e", and so on until the entirety or bar has been encrypted using foo for the letters. and then print the new bar but with the letters changed from the encrypton process.
i hope that makes sense, and i really hope someone out there can help me! thank you so much for any help!

How to change the coordinate system in OpenGL

void handleResize(int w, int h) {
//Tell OpenGL how to convert from coordinates to pixel values
glViewport(0, 0, w, h);
glMatrixMode(GL_PROJECTION); //Switch to setting the camera perspective
//Set the camera perspective
glLoadIdentity(); //Reset the camera
gluPerspective(45.0, //The camera angle
(double)w / (double)h, //The width-to-height ratio
1.0, //The near z clipping coordinate

When I try to use the `onClickListener` method on the a button variable outside of any `onCreate or onPause or onAnything` method, it does not work. I also cannot even set the value of a button variable outside of an "onAnything" method. Help would be great.

php create dynamic html table
|
I need to create a dynamic html table using PHP after parsing a JSON file.<br> I need this column structure for my table; `Name | Status | Age | Count | Progress | Bad`<br><br>
How can i create a new row for every 'record' parsed from the JSON file (i can create a tab separated string).<br>An additional difficulty is that some 'records' only contain data for the column 'Name' and others for all columns.<br><br>
So my question is how to add a row dynamically to the table and fill the right column ?<br>
(*The key form the JSON file is the column header*)<br><br>I hope my question is sufficiently clear.<br>Thanks in advance.

Excluding bootstrap.html or index.html from the history stack with jQuery mobile
|
I'm creating a mobile application using jQuery mobile and PhoneGap.
When the application is started, the frontpage will be loaded dynamically. What frontpage will appear depends on certain states, for example whether the app has been configured.
This is why I have a bootstrap.html, which only loads all code and has no body. Some logic then calls ```jQuery.mobile.changePage``` to load the desired frontpage.
The issue is that bootstrap.html, which is empty, will be put in the application's history stack. When the user then presses the back button, he or she will go to this empty bootstrap page. This is undesirable behavior.
Is it possible to exclude this bootstrap file from the history stack with jQuery mobile?

GPU perfomance request, what's the best solution?
|
I work on an audio processing project with some friends and we need to do a lot of basic computations (+, -, *) like a FFT (Fast Fourier Transform) calcul.
Also we don't have lot of money, about 500$.
So we think about use graphic card to accelerate this computations. But we don't no if this is the best solution, and all the existing solutions to have a good computation system under 500$.
For information we use Matlab programming, and we have a sound card acquisition which have to be plug in the system.
Here is my question, do you know other solution than graphic card with motherboard to do lot of calculus?
Thank you.

Multiple objects tracking algorithm
|
I need to solve the following problem: suppose i have a sequence of images, with detected traffic signs (i have bounding boxes around this signs). Traffic signs can be occluded by cars, trees and so on. The problem is to link each physical sign with it's detections on each frame. Can you give me the link to the appropriate matlab code please, which can help to solve this problem. Any general ideas are welcome too.

How to REALLY delete a git branch (i.e. remove all of its objects/commits)?
|
I have a git tree like
A---B---C topic
/
D---E---F---G master <--
I would like to remove topic and all objects on it.
I note the SHA ID of topic, then type:
git branch -D topic
git gc # <-- I also tried prune here...
git checkout -b temp <SHA1 ID of topic>
After the last command I expect to get an error (something like "Non-existent object ID..." or somth. like that). However there is no error and gitk shows the same tree structure as above??
What am I missing - I thought gc/prune are supposed to delete all unreachable objects?

**3) if you know any method to get it done through java ... then please give me the exact codes without any errors....i dont know coding that much ...i just started coding.**
**Note:** Please dont ask me to use html2exe converter .....i tried using that but some javascript and html frames dont work. if you know any other software which can do the job correctly then please let me know. And please give detailed explanations in your vb codes .....i am a newbie in vb just started learning 3 days ago...
The idea:

typedef struct { double u, v; } projUV;
typedef void *projPJ;
#define projXY projUV
#define projLP projUV
#else
typedef PJ *projPJ;
# define projXY XY
# define projLP LP
#endif
typedef struct PJconsts {
XY (*fwd)(LP, struct PJconsts *);
LP (*inv)(XY, struct PJconsts *);
void (*spc)(LP, struct PJconsts *, struct FACTORS *);
void (*pfree)(struct PJconsts *);
const char *descr;

int geoc; /* geocentric latitude flag */
int is_latlong; /* proj=latlong ... not really a projection at all */
int is_geocent; /* proj=geocent ... not really a projection at all */
double

a_orig, /* major axis before any +proj related adjustment */
es, /* e ^ 2 */
es_orig, /* es before any +proj related adjustment */

PHP is a compiled language since PHP 4.0?
|
I am in doubt after reading [This Article][1]. I had read on several forms and articles that php is an **interpreted** language, even i found the same thing with [Stackoverflow][2] but when i read it from [here][3] I got confused. Can anyone explain me about this with certain authenticated links or refrences.

Difference between different methods for calculate the page load time
|
**First method**
$start = microtime(true);
// code
$end = microtime(true);
echo 'This page loaded in '.round($end - $start, 4).' sec';
**Second method**
$time = microtime();
$time = explode(' ', $time);
$time = $time[1] + $time[0];
$start = $time;
// code
$time = microtime();
$time = explode(' ', $time);
$time = $time[1] + $time[0];
$finish = $time;
$total_time = round(($finish - $start), 4);
echo 'This page loaded in '.$total_time.' sec';
What is the difference between them and which one is better ? And also do you have other suggestions?

Bash control+c process

I have a couple of servers each that have a 'screen' that is running a program. This way, i am able to ssh in and monitor their out putat any given time.
The problem, is that i am often having to ssh in, log into the screen, control+c the process and then restart it.
I would like to write a bash script that would do this for each of my servers, and i think i understand how to do it, aside from the control+c bit.
ssh ubuntu@ipaddress

openswan l2tp server to android client
|
I'm trying to figure out how to set up openvpn on my linux mint so I can connect to it with my android (T-Mobile HTC MyTouch 4G Slide) device. I think I'm part way there but I am still having fits getting it to connect.
So far I have installed openswan, openssl and tinyca
I was able to create a CA certificate and a request certificate in tinyca. If I am reading it correct it creates them using the openssl settings so I copied the /etc/ssl/cert/MyserverCert.pem and /etc/ssl/private/MyserverKey.pem to the appropriate directories in /etc/ipsec.d/*
I copied the example l2tp-psk.conf into /etc/ipsec.d/ and modified the left to my eth0 interface address, and leftnexthop to my router address, saved then restarted ipsec service.
I generated a Myserver.crt file using tinyca from the existing ssl keys and sent it to my phone and was able to import it.
Where I'm confused is when I try to set up an L2TP PSK vpn in my phone, it is asking for 'username'. It also has a setting when you set up the connection that asks for 'IPSec pre-shared key' - I'm assuming this is the name I gave the .crt settings when I imported them?
Any other tips/suggestions would be greatly appreciated (like where to look in log files to see what might be failing and why both on the phone and on the server)
Thanks in advance for any tips!

Is Qt Quick mature enough for large desktop applications?
|
I'm planning to write a program that is especially designed for tablets, the main platform is MeeGo (because I'm taking a contest), so Qt is the only toolkit to choose.
As the UI is highly designed for tablets, I will customize most of the UI components. So I have two choices, one is to use classic C++ ways to paint all of them, which is hard but familiar to me, another is to use the new Qt Quick.
Qt Quick is great at first glance, but after a few days' exploring, I found it rather tough. It lacks many important components. And as far as I can see, it is very hard to use Qt Quick to generate dynamic contents (like what the Flipboard app does).
My program will need C++ to do lots of heavy low level things, and meanwhile it requires a highly customized and very dynamic GUI. Is Qt Quick mature enough for my purpose now?

C governs variables to be declared at beginning
|
C- language governs that all variables used in the program should be declared before any other statements. <br>
Why was this of significance? Was it for readability? if it was for readability, then why don't other languages follow the same rule?
I personally prefer declaring all my variables at the very start.

How can I store two values associated with an image in an array?

I'm trying to figure out a way I can store and associate a letter (a-z), a value (1-10), and an image with each other. For example, lets say that associate:
A with 2 with letterA.png
B with 1 with letterB.png
..etc
I'm thinking that I need some kind of array. It would be nice if I could use the letters as the indexes.

The lua stack overflow,is this a bug?
|
I use lua some years, thank you all for developing lua language!
Some days ago, our program crash. I found the crash in lua code. So I check lua code, found the stack overflow.
Please look this code In function luaD_precall:
1 if (!cl->isC) { /* Lua function? prepare its call */
2 CallInfo *ci;
3 StkId st, base;
4 Proto *p = cl->p;
5 luaD_checkstack(L, p->maxstacksize);
6 func = restorestack(L, funcr);
7 if (!p->is_vararg) { /* no varargs? */
8 base = func + 1;
9 if (L->top > base + p->numparams)
10 L->top = base + p->numparams;
11 }
12 else { /* vararg function */
13 int nargs = cast_int(L->top - func) - 1;
14 base = adjust_varargs(L, p, nargs);
15 func = restorestack(L, funcr); /* previous call may change the stack */
16 }
17 ci = inc_ci(L); /* now `enter' new function */
18 ci->func = func;
19 L->base = ci->base = base;
20 ci->top = L->base + p->maxstacksize;
21 lua_assert(ci->top <= L->stack_last);
22 L->savedpc = p->code; /* starting point */
23 ci->tailcalls = 0;
24 ci->nresults = nresults;
25 for (st = L->top; st < ci->top; st++)
26 setnilvalue(st);
27 L->top = ci->top;
In my program, the p->maxstacksize is 79 before line 5, the current stacksize is 51, after call luaD_checkstack,the stacksize grow to 130.
The lua function use vararg, so will run to line 14. Function adjust_varargs will be called.
static StkId adjust_varargs (lua_State *L, Proto *p, int actual) {
int i;
int nfixargs = p->numparams;
Table *htab = NULL;
StkId base, fixed;
for (; actual < nfixargs; ++actual)
setnilvalue(L->top++);
#if defined(LUA_COMPAT_VARARG)
if (p->is_vararg & VARARG_NEEDSARG) { /* compat. with old-style vararg? */
int nvar = actual - nfixargs; /* number of extra arguments */
lua_assert(p->is_vararg & VARARG_HASARG);
luaC_checkGC(L);
htab = luaH_new(L, nvar, 1); /* create `arg' table */
In function adjust_varargs(), the lua function use “arg”, So luaC_checkGC will be called.
In luaC_checkGC, the current lua stack size will be reduce to 65!
The call stack like this:
luaC_step()- singlestep()-propagatemark()traversestack()checkstacksizes()luaD_reallocstack()
But the p->maxstacksize is 79, the stacksize is not enough…
When the program run to line 27,the L->top is bigger than L->stack_last, in the next operation, will cause crash!
Thank you!

3 StkId st, base;
4 Proto *p = cl->p;
5 luaD_checkstack(L, p->maxstacksize);
6 func = restorestack(L, funcr);
7 if (!p->is_vararg) { /* no varargs? */
8 base = func + 1;
9 if (L->top > base + p->numparams)
10 L->top = base + p->numparams;
11 }
12 else { /* vararg function */
13 int nargs = cast_int(L->top - func) - 1;
14 base = adjust_varargs(L, p, nargs);
15 func = restorestack(L, funcr); /* previous call may change the stack */
16 }
17 ci = inc_ci(L); /* now `enter' new function */
18 ci->func = func;
19 L->base = ci->base = base;
20 ci->top = L->base + p->maxstacksize;
21 lua_assert(ci->top <= L->stack_last);
22 L->savedpc = p->code; /* starting point */
23 ci->tailcalls = 0;
24 ci->nresults = nresults;
25 for (st = L->top; st < ci->top; st++)
26 setnilvalue(st);
27 L->top = ci->top;
In my program, the p->maxstacksize is 79 before line 5, the current stacksize is 51, after call luaD_checkstack,the stacksize grow to 130.
The lua function use vararg, so will run to line 14. Function adjust_varargs will be called.
static StkId adjust_varargs (lua_State *L, Proto *p, int actual) {
int i;
int nfixargs = p->numparams;
Table *htab = NULL;
StkId base, fixed;
for (; actual < nfixargs; ++actual)
setnilvalue(L->top++);
#if defined(LUA_COMPAT_VARARG)
if (p->is_vararg & VARARG_NEEDSARG) { /* compat. with old-style vararg? */
int nvar = actual - nfixargs; /* number of extra arguments */
lua_assert(p->is_vararg & VARARG_HASARG);
luaC_checkGC(L);
htab = luaH_new(L, nvar, 1); /* create `arg' table */
In function adjust_varargs(), the lua function use “arg”, So luaC_checkGC will be called.
In luaC_checkGC, the current lua stack size will be reduce to 65!
The call stack like this:
luaC_step()- singlestep()-propagatemark()traversestack()checkstacksizes()luaD_reallocstack()
But the p->maxstacksize is 79, the stacksize is not enough…
When the program run to line 27,the L->top is bigger than L->stack_last, in the next operation, will cause crash!
Thank you!

MVC: Restrict access to execute .aspx scripts in specific path location

For some reasons, sometimes may occurr that some .aspx files could appear in /Uploads/Photo/Avatar folder, and I want to restrict access to deny execution .aspx or any other scripts inside this folder.
Anyway, files like .jpg .gif and other should be accessed (but not executed) by IIS.
What is the best way to configure web.config, or maybe setup Routes in global.asax

pass variable from href to another php page
|
.I have this code:
<a id="various3" href="picture.php?id=',$pid,'" title="'.$info.'"><img src="picture.php?id=',$pid,'" width="150" height="210"></a>
it passes the id to my picture.php where i use it on a query string.
$sql = sprintf("select pics, ext from `06-07` where id='%d'",$_GET['id']);
Is it possible to pass more than one variable using this method? because i would like to pass "dept" along with the "id". if it is then how?

I have some C language assembly code

I have some assembly code from a program that i have to try to understand by looking at the assembly code and debugging. Im having trouble getting started. What do the different commands (push, mov, sub, test, je) mean?? Along with the %esp and %ebp, and $0x18 etc etc, what do they mean? Does anyone have a table that labels all these different commands?
Any help would be appreciated. I hope this isnt too vague please dont delete my question.
the two methods i want to look at are phase1 and phase2.

Has Ubuntu reached the point yet where it's user friendly for most users?
|
I remember once before (1-2 yrs ago) if you needed to configure ANYTHING in Ubuntu, you needed to go use the command line. How is it today? Can I use it as my full desktop? Can I take it to presentations around the country and not embarrass myself because the projector won't work? Does it work well when I have to connect to various static networks?
Basically, is it user friendly enough that I don't need to fight it in order to do things.
Note: After my last experience, I absolutely positively refuse to use command line.

DLL not working
|
Recently, I decided to get into DLL programming with C++.
I made a simple DLL but when I inject it into a process, nothing happens.
Here's the code:
#include <windows.h>
BOOL WINAPI DllMain(HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved)
{
if(fdwReason == DLL_PROCESS_ATTACH){
MessageBoxA(0,"Injected","Injected",MB_OK);
}
return TRUE; // succesful
}
It's supposed to display a message box when it gets injected into a process, but it doesn't work.
Any help would be appreciated

Passing an array of Char s through a method
|
I have two blocks of code, the second of which works fine. I am trying to pass the second method an array of characters that represent a file name. My methods are as follows:
void addFile(const char* file)
{
...
readFile(file);
}
File(const char* file)
{
...
}
When I pass a file name directly into the second method, it works fine, but when I try to do the above, it fails when I try to compile with the message: "error: no matching function for call to File::File(const char**)". The two functions are in different classes, but I have no issues calling methods from the seconds class with any of my other methods from the first class. What is the compiler looking for that I don't have?

austDay = new getSeconds(austDay);
var duration = 1200;
duration += austDay;

Given single-linked list:
A -> B -> C -> D -> E
Given a pointer pointed to C (ptr = &C), and a new node F, how to get
A -> B -> F -> C -> D -> E
Attention: we do not have pointers pointed to A.

Have no idea how to imlpement Quicksort
|
I am trying to implement quicksort in this for just research. But i have no idea how quicksort works im looking at this algorithm but have no idea what or how to implement it right now im using bubble sort but how do i go ahead and implement quicksort?
# choose pivot
swap a[1,rand(1,n)]
# 2-way partition
k = 1
for i = 2:n, if a[i] < a[1], swap a[++k,i]
swap a[1,k]
→ invariant: a[1..k-1] < a[k] <= a[k+1..n]
# recursive sorts
sort a[1..k-1]
sort a[k+1,n]
This is my code below
int main()
{
srand(time(NULL));
int length = 250000;
double arr[length];
for(int i = 0; i<length; ++i) arr[i] = rand();
// mergeSort2(arr, arr+length-1);
for(int i = 0; i < (length-1); i++)
{
for(int j = i+1; j < length; j++)
{
if( arr[i] > arr[j])
{
swap(arr[i], arr[j]);
}
}
}
ofstream ofs("input.txt");

Php title issue
|
Hi Ive tried to find an answer to this but nothing seems to be helping
I have my page setup as
- **index.php, skills.php** and **contact.php**
I also have setup an **include folder** which contains
- **header.php** and **footer.php**
currently using the include function to put the header and footer within the seperate pages above.
However im trying to write a script for variables that allows
- **$title, $page_width**, **$meta_description, $meta_keywords**
That replace the information in the **header.php** file dependent on which page is loaded above.
Ive tried numerous things but none seem to work, just keep getting php errors.
Thanks for any advice on this

Resource Files how to name them?
|
I am playing around with resource files and have run into a problem.
I have a folder called Languages. When I make a resource file and say call it "R.resx" I can call this resource file up in my classes.
If I rename this file(or delete and make a new resource file) and call it R.en.resx I **cannot** call this resource file up in my class anymore.
Does the first language need to be in R.resx where the rest would be R.language.resx?

How many users per CPU core to keep my website fast?

I'm building a social network type of website, and I am going to be setting up hosting servers for it to run on, I'm just wondering what the number of users per CPU core is recommended to keep my website going fast for everyone. Say I were to have 1 Million users on my website at any given time, I want them each to have optimal speeds at doing anything.
Thanks.

Bind List(Of String) to Repeater
|
How can I bind a simple list of strings to a repeater?
Protected Sub Page_Load(sender As Object, e As System.EventArgs)
'create sample data:
Dim photos As New List(Of String)
photos.Add("large1.jpeg")
photos.Add("large2.jpeg")
photos.Add("large3.jpeg")
photos.Add("large4.jpeg")
photos.Add("large5.jpeg")
'bind data:
Repeater1.DataSource = photos
Repeater1.DataBind()
End Sub
The HTML is simply:
<asp:Repeater ID="Repeater1" runat="server" ClientIDMode="Predictable">
<HeaderTemplate><ul></HeaderTemplate>
<FooterTemplate></ul></FooterTemplate>
<SeparatorTemplate>
<li>
<asp:Image ID="img_photo" runat="server" ImageUrl="<%# Container.DataItem %>" /></li>
</SeparatorTemplate>
</asp:Repeater>
The value from Container.DataItem is always empty.
Any ideas?

htaccess rewrite adds "index.php" when I add a trailing slash to an address
|
I've got my htaccess rewriting on the following rules:
RewriteRule ^([a-zA-Z0-9\-]*)/([0-9]*)/([a-zA-Z0-9\-_]*)$ /content.php?a=$1&b=$2&c=$3
RewriteRule ^([a-zA-Z0-9\-]*)/([0-9]*)$ /content.php?a=$1&b=$2
RewriteRule ^([a-zA-Z0-9\-]*)$ /index.php?a=$1
that works wonderfully when i go to "mydomain.com/nameofpage/id"
but when i add a trailing slash "mydomain.com/nameofpage/id/" the browser adds "index.php" to the end and 404's me.
Thoughts?
Thanks!

To Silverlight or XNA?
|
I want to make a Windows Phone app, but apparently there's a lot of confusion as to the future of the Windows product. It seems they're going to shift away from their proprietary technologies in favor of HTML5 and Javascript. Or, that is at least the current suspicion, and Microsoft has delayed any final wording until September.
So, I'm caught in the middle. What platform should I choose to develop this standard app, Silverlight or XNA? For now, either option would be okay, but I don't want to remake the app from scratch for Windows 8.

How to compare two eclipse installations for missing features?
|
I have two coexisting installations of eclipse on my machine. One is the plain eclipse and one is STS (Spring Sourct Tool Suite). For some strange reason (which would be too tedious to explain here) I have to use the plain eclipse. However, I want to import, use some of the plugins that already exist in STS.
Is there a way I can go about achieving this?

Is it unhealthy to program 60+ hours per week?
|
I'm in my early twenties and I work a lot. Is it unhealthy to program this much and often much more? I know this is subjective, but the question has been nagging me a lot lately.
EDIT:
To clarify, despite spending a massive amount of time at the keyboard, I have an otherwise relatively healthy lifestyle. Eat (mostly) right, exercise a few times per week, and take 1-2 nights per week to just socialize.

What is the purpose of CTRL+T and CTRL+SHIFT+T in all modern text editors?
|
I have seen this in countless text editors, including Visual Studio.
Can anyone explain where is this useful for?
So far i have only managed to break my undo/redo chain with it countless of times. (tried to hit `CTRL+Y` but instead i hit `CTRL+T` == ARGH!).
Today i noticed there is even worser shortkey in Visual Studio 2008: `CTRL+SHIFT+T` - its similar to `CTRL+T` but actually much worse:
int some_funny(){
return stuff;
}
void hehe(){
return haha;
}
bool finished;
Becomes (after dozen of CTRL+SHIFT+T hits):
some_funny return(){
stuff void;
}
hehe return(){
haha bool;
}
finished int;
I dont understand how this can possibly be useful for anybody.

/* You are writing a unit test to confirm the correctness of a function which

Cnoverting application to MVC architecture
|
I'm practicing writing MVC applications. I have a Mastermind game, that I would like to rewrite as MVC app. I have divided my code to parts, but instead of working game I'm getting empty Frame and an error in "public void paint( Graphics g )". Error comes from calling this method in my view with null argument. But how to overcome this ? MVC was quite simple with swing but awt and it's paint methods are much more complicated.
Code of working app :

Any clues on how to overcome this would be great. Have I divided my code improperly ?

C++ pair delete error

I have the similar code as follows
pair<int,int> *findPair(){

for(int i=0;i<10;i++)
{
t[i].first =1;
t[i].second =2;
}
return t;
}
int main() {
pair<int, int> * tt = findPair();
tt[1].first =8;
delete [] tt; // error
return 0;
}
There is segment fault error. I have similar code and `new pair` but get segment fault.

TCP issue: sending data to specific client from server on vvvv
|
I have few questions to ask about TCP on vvvv.
First, is it impossible to TCP Server to send data only to clients I choose, not every client?
I need to send different data to different clients, but I noticed that TCP Server node seems that it has no pins to manipulate such operation.
I have no idea if this problem is of vvvv or of TCP communication itself.
Second, is there any way to access to core code of existing node, like editing dynamic plugins?
Thanks for reading and paying attention.
Every answer will be greatly appreciated and help me a lot!

I have an out of browser app with silverlight.
If I switch to winrt can it automatically update like silverlight does or is it just like a WPF app.
Where can I learn about winRT as a cloud app?

Facebox not working on elements loaded into specific div with jQuery
|
just want to put it out there, that I have searched all over stackoverflow and google but couldn't resolve my problem with the help I found.
I have a weekly calendar, which days are separated into div elements. Each div has an ID of d-m-Y. I use a mix of php and jQuery to load events into days of the selected week.
Below is the mix of jQuery and PHP that does just that (loads events into certain days of the week).
echo "<script type=\"text/javascript\">
jQuery(document).ready(function($) {
$('a[rel*=facebox]').facebox({
loadingImage : '/scripts/facebox-v1.3/loading.gif',
closeImage : '/scripts/facebox-v1.3/closelabel.png'
});
$(document).bind('beforeReveal.facebox', function() {
$(\"#facebox .content\").empty();
});
";
for($day=1; $day<=5; $day++) {
echo "$('#".date('d-m-Y', strtotime($year."W".$week.$day))."').append( $('<div />').load('/cal/load #".date('d-m-Y', strtotime($year."W".$week.$day))."' ));\n";
}
echo "});
</script>";
Below is the data that gets loaded into the specific div.
echo "<div id='".date('d-m-Y', strtotime($event['timeStart']))."' style='width: 100%; height: ".$eventLong."px; top: ".$eventPosition."px; left: 0%; position: absolute; z-index: 1; background: #C30;'><a href='#' rel='facebox'>Delete</a></div>";
My problem is that I can't get facebox to work - I want to achieve that when I click on the delete button, facebox pops out.

PHP viewing a file as hex?
|
I had looked for a way to view a file as hex a while ago and found:
class Hex
{
var $file;
var $hex;
function __construct($file)
{
$this->file = $file;
}
function gethex()
{
$handle = fopen($this->file, 'r') or die('Permission?');
while(!feof($handle))
{
foreach(unpack('C*',fgets($handle)) as $dec)
{
$tmp = dechex($dec);
$this->hex[] .= strtoupper(str_repeat('0',2-strlen($tmp)).$tmp);
}
}
return join($this->hex);
}
function writehex($hexcode)
{
foreach(str_split($hexcode,2) as $hex)
{
$tmp .= pack('C*', hexdec($hex));
}
$handle = fopen($this->file, 'w+') or die('Permission?');
fwrite($handle, $tmp);
}
}
It worked great for one file, but I think I'm running into problems with trying to do it with multiple files. Is there anything wrong with the script? Should it close the files somewhere? Should I delete the instances of it after using them?

Document conversion and viewing, what are the cutting edge solutions?
|
Goal: building a web application where a user can:
1. Upload a document (doc, docx, pdf, additional office formats a +)
2. View that document in a browser, preferably in html
3. Download the document (in doc, pdf, additional open formats a +)
Current solution:
- Ruby on Rails Application on Rackspace
- Users can upload doc and pdf files (AWS)
- Files can be downloaded in the format in which they were uploaded
- Thumbnail generation ([doc, pdf] -> pdf -> png) is done through AbiWord. Certain doc files do not convert well.
- Documents can be viewed in embedded Google docs viewer (https://docs.google.com/viewer). Certain doc files cannot be displayed. Little flexibility.
Potential improvements:
- Document viewing in pdf through [pdf.js][1]
- Viewing in html (+ annotation) through [Crocodoc][2]
I'd be glad to hear other users' experiences, and will add good recommendations to this list.

How to implement a custom ColumnSorter with ScrollTable (GWT-incubator)
|
I've implemented my custom column sorter which is used to sort the
elements in my table.
<pre>
class FileColumnSorter extends SortableGrid.ColumnSorter
{
@Override
public void onSortColumn(SortableGrid sortableGrid, TableModelHelper.ColumnSortList columnSortList,
SortableGrid.ColumnSorterCallback columnSorterCallback)
....
}
</pre>
When I initialize the FixedWidthGrid I do the following:
<pre>
FixedWidthGrid dataTable = new FixedWidthGrid(rows, cols);
dataTable.setSelectionPolicy(SelectionGrid.SelectionPolicy.ONE_ROW);
dataTable.setColumnSorter(new FileColumnSorter());
</pre>
The scrolltable is initialized the following way:
<pre>
FixedWidthFlexTable headerTable = createHeaderTable();
// Calling the lines described above
FixedWidthGrid fileListGrid = createDataTable
(currentDescriptorList.size(), 6);
// Combine the components into a ScrollTable
scrollTable = new ScrollTable(fileListGrid, headerTable);
scrollTable.setSortPolicy(AbstractScrollTable.SortPolicy.SINGLE_CELL);
scrollTable.setColumnSortable(0, false);
scrollTable.setColumnSortable(1, true);
scrollTable.setColumnSortable(2, true);
scrollTable.setColumnSortable(3, true);
scrollTable.setColumnSortable(4, true);
scrollTable.setColumnSortable(5, false);
</pre>
When I run the application, I get the built in sorting instead of my
custom sorting. I've also tried to do the following:
<pre>
ColumnSorter sorter = new FileColumnSorter();
FixedWidthGrid dataTable = new FixedWidthGrid(rows, cols) {
@Override
public ColumnSorter getColumnSorter()
{
return sorter;
}
};
</pre>
To ensure that my sorter get used, but I still get the same
experience.

let child dom element out of bounds of the parent div with html and javascript on hover
|
Very hard to summarize in the title what the question is exactly
so more info here...
an image-gallery consisting of a list element with images (and a span to display a text label).
the html layout looks like this:
<div class="caracteristics_list gallery">
<ul class="thumb">
<li><a href="#"><span class="video">Play</span><img src="images/gallery1.jpg" alt="" /></a></li>
<li><a href="#"><img src="images/gallery1.jpg" alt="" /></a></li>
<li><a href="#"><img src="images/gallery1.jpg" alt="" /></a></li>
<li><a href="#"><img src="images/gallery2.jpg" alt="" /></a></li>
<li><a href="#"><img src="images/gallery2.jpg" alt="" /></a></li>
<li><a href="#"><img src="images/gallery2.jpg" alt="" /></a></li>
<li><a href="#"><span class="tagline">Lorem ipsum</span><img src="images/gallery3.jpg" alt="" /></a></li>

<li><a href="#"><img src="images/gallery4.jpg" alt="" /></a></li>
<li><a href="#"><img src="images/gallery4.jpg" alt="" /></a></li>
</ul>
</div>
this gallery has a zoom effect ([taken from this guide][1] ([demo][2]))
the catch here is that the gallery has a fixed width, and height
and a overflow: scroll (it does not grow it is contained within the bounds of that gallery div.
that means, the zoom effect is cut of by the overflow css settings.
an example of what i have now (with broken images though) [can be seen on jsfiddle here][3]
I fear the overflow constraint will make this method impossible, unless i take the element out of the gallery div, and position it exactly at the same spot absolute or relative.
but first i want to make sure that is the only way to go.
thanks

WCF Service Library Connection Issue to DAL in an ASP.NET web application
|
I have the following set up in the same solution.
- A WCF Services Library with one main service called MatchService.cs
- A DAL with a EntityDataModel for my classes which retrieves my information about football matches from a DB
- An ASP.NET Website which is hosting the WCF Service Library Match Service (from the WCF service libracy mentioned above)
My problem is that this fine runs locally, but not on the production server. Locally the WCF project has an app.config from which it gets the connection details for the DB DAL, however I'm thinking that this does not get put into the compiled .dll for the WCF Services Project as I get the following error when I upload this to the production site:
"The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be used for communication because it is in the Faulted state."
So I thought it would attempt to get the DB details from the web.config, however this does not seem to be the case either.
Can anyone let me know what I'm doing wrong?

Using spaced repetition to retain programming knowledge
|
Has anybody successfully used spaced repetition concepts embodied in programs like supermemo in the context of programming ?
The motivation for this question: I'm increasingly having to look up things I knew.
Reading this Wired piece <a href="http://www.wired.com/medtech/health/magazine/16-05/ff_wozniak">"Want to Remember Everything You'll Ever Learn? Surrender to This Algorithm"</a> has me wondering if this has worked in practice for anybody. I'm talking about using it to remember programming snippets, keywords, APIs etc so I don't have to browse through "X in a Nutshell" just to refresh my memory.

Using spaced repetition to retain programming knowledge
===
Has anybody successfully used spaced repetition concepts embodied in programs like supermemo in the context of programming ?
The motivation for this question: I'm increasingly having to look up things I knew.
Reading this Wired piece <a href="http://www.wired.com/medtech/health/magazine/16-05/ff_wozniak">"Want to Remember Everything You'll Ever Learn? Surrender to This Algorithm"</a> has me wondering if this has worked in practice for anybody. I'm talking about using it to remember programming snippets, keywords, APIs etc so I don't have to browse through "X in a Nutshell" just to refresh my memory.

Future Of The Browser - Open Client Hardware API Initiatives?
|
Are there any initiatives to implement/agree upon a standard API for connectivity between web browsers and specific pieces of client hardware.
Example: The iPhone has a GPS/Camera/Accellerometer in it. It'd be very cool if my web app could communicate with them (rather than me having to write a thick ObjectiveC application).
