Try looking at the Call Stack (one of the tabs at the bottom in Visual Studio) to see where the current method/function is being called. You'll get a hint at which call went wrong.

There are many reasons behind this, I think this is due to the memory over usage. If you allocate N Bytes of memory but >N Bytes of memory is used and then you try to delete the memory it gives the same problem. Check in the code the memory should not be over used.

Are you debugging the DEBUG mode application or RELEASE mode Application.If you try to DEBUG MODE application, the debugger will point you actual line of fault.

Thank you for your reply.
I do debug the release version - where I can see only the assembly code. The debug version never crushes - since as far as I know the debug version does handle a little bit diffrent the events.

Thank you. I will read the article and maybe find the cause of the problem.

You may want to use PJN's excellent CExceptionLogger[^] to identify problems in release builds. I've used it with great success in the past - it's a real lifesaver!
Caveat: for accurate identification of problematic code, you'll need to disable optimization.

You have probably heard this a million times, but one of the first things to check when your releasse crashes and debug does NOT is to search for the use of uninitialized variables - especially ANYTHING that is a pointer. Maybe you can set your compiler to warning level 4 (if you have not done so already), and if you thought the 'use of X before it has been initialized' was just warning, then you should treat all of those as errors.

Hello,
Well - I was not able to solve the problem ... but I had developed a work around which I think is the solution is your case as well.
You are using CString - which is very easy to use. Try LPSTR.

Dan.

Hey all,
I've got an application running the XP Style interface where the scroll bars are nicely shaded, buttons are highlighted, etc. However, in any CWnd derived class, if I call ShowScrollBar(), the scroll bar will still look like the old pre-XP style scroll bar. However, this problem does not happen in common MFC classes like CScrollView or CListCtrl - only my own CWnd classes. It looks horrible when the rest of my app is in the XP style look. Any suggestions?
To reproduce the problem, I think all one needs to do is create a new CWnd somewhere and call ShowScrollBar(). It will sport the old look, rather than the new XP look.
EDIT: I solved this problem. If anyone is interested, such behavior occurs when ShowScrollBar() is called before SetScrollRange() or SetScrollInfo() is called to set up the non-client scrollers.
|

|

Do you find that if you call SetScrollInfo and specify the nPage size in the structure to resize the thum, the scroll bar doesn't scroll all the way to the max value?
I can't find the correct way to fix this other than changing the max value.

Hello there,
I have a problem with the order of how folders and files are listed when I use CFileDialog-class.
Normally when calling the box, it first lists all folders then all files (in alphabetic order).
For some days now the order is reversed. So first all the files THEN all the folders. I can change the order each time with help of the "options" button (==> Show Details ==> then click on "Name") but I have to do that each time I use the CFileDialog in my program.
Actually the same thing already happens in only AOME of my windows programs (e.g. in Netscape yes but in Word not...)
Anybody any idea?? Any help or hint is appreciated!

I have some utility functions that I would like to put into a library. I want the library to be used like you would for example the cos(x) function from the math library.
All you have to do is include the header
#include <math.h>
Then you can use the function
float result = cos(somenum);
How do you accomplish this?
|
|
|
|
|
Create a static library project containing your utility functions (menu File->New->Project, choose Visual C++ Projects, then select the template Win32 Project. Finally in the wizard, select the Static Library option). Once compiled your will get one .h and one .lib file, which you can include within your other projects.
|
|
|
|
|
Thanks for the response. I will try that once I get a moment.
Will I need to extern "C" the functions or anything else special?
|
|
|
|
|
To make a utility function in a library available for use, you need something like the following in your .h file:
extern "C"
{
declspec(dllexport) void MyFunc(int i);
}

Imagine a situation in which Dialog Box added to TabCtrl is bigger. Than I think TabCtrl should provide a scrollbar. But I am not getting any ScrollBar. So what might be the problem. Is it by default or I have to set some properties.
Thanks

Thanks for replyieng.
I tried a simple sample program and I am not able to see both horizontle and verticle scrollbars. I mean they are not visible by default. Do I need to enable certain properties ?
Thanks again.

ok ! could some one quide in this :- we have game project where each room is currently run by running the same game server application for each room , in other words for multiple rooms multiple instances of same game server exe are run . Because threads are not used it takes more memory if we need to run large number of rooms by running the same server exe number of time equlal to the rooms .
The current application is developed in a single dialogue box which has all the code and which manages the sockets . now we need to make whole thing in single game server application using threads to run numtiple rooms within . so can some one tell that , can we use the current version and us it into new appication and have it run the same code into new threads to add new room each time and will we need to make the application communicate from one main port or can we have the old code run in new thread and let it open an unique port for ecah room .
What would be a right approach to making such an application which can run 500 such rooms in other words 10000 concurrent users as each room have 10 live players .
