I need to catch the 0xC0000005 Exception in my code. I've tried try{}catch(CException *e){}, but it didn't work.

I think you are on the look out for First and Second chance exception[^]
You need to google first, if you have "It's urgent please" mentioned in your question.

Well, I've already searched Google, And I found using SEH could resolve this problem. But in my case, the code which throw the Exception is a dll. So the SEH didn't work for me.

normal C++ not handling "0xC0000005 Access Violation Error"" exception, you need to give more compiler option to handle it.
but you can try "__try __except", exception handling of C, it will help you. Usage[^]

Thanks for your suggestion!
I tried it before, but it didn't work. Anyway, I found it is better to fix this problem in the dll file which throw the exception using __try__catch.

I am writing a code to do a long time draw like:
void MyDialog::DoSlowDraw(DWORD tDelay){
while(notFinished){
DrawNextLine();
Sleep(tDelay);
}
}
And it's better to have a "cancel button" because it may take a long time according to tDelay.
---------------------
 My try:
To handle "cancle button clicked Message" , Drawing must be done by another thread.
UINT DrawProc( LPVOID pParam )
{
CMyDialog* pform = (CMyDialog*)pParam;
int timeDelay = pform->timeD;
Line_list* pLines = pform->m_pLines;
CClientDC cdc(pform);
It's worked, but as far as I know
1. Work thread should not touch the GUI ---- (Do the drawing).
2. MFC object should not passed to another thread ---- (passing drawing data by CMyDialog*)
 Is there a good way to cancle long time drawing.

I understood you perfectly. If you are drawing in a worker thread and you need to cancel that thread, my advice is the way to go. Using a message pump is an antiquated and largely unused 16-bit Windows solution.

Sorry for my late response,(I am in a busy work now)
You are right, but before that,
Do you think it is OK to draw in the work thread?
I mean, a good design? because drawing is touching the GUI I thought, maybe I was wrong.

I would think not. Have the worker thread post a message to the main thread (that owns the UI).

I am writing a code to read the bits from the file. Starting from first bit, i can read the whole file, and can retrieve the whole data as well. But if i want to retrieve the bits from somewhere between the file, how should i do this? One more thing, i am doing a string comparision of a module(and that module repeats several times in the file) and then i am retrieving the bits hence i can,t apply character counting.
It was a woman who drove me to drink but I never got opportunity to thank her

It depends on how you are reading your file. Are you using an ifstream, a FILE, a CFile, ... ? Typically, you can set the file pointer (e.g. CFile::Seek, ifstream::seekg, ...). You should look at the documentation for more information.

Read the file in binary mode completly in a buffer, and than you can do what you want.

Hi,
I would like to build an win32 application which sould not inherit from explorer.exe. By default all MFC/Win 32 applications are loaded in explorer.exe. so any crash of application is causing crash to explorer and vice versa..
So i need to find out a way where my application wont be loaded in explorer.
Thanks in advance.

I will tell you a trick, try to figure out where your application is crashing and why.
Fix the bug.

Obviosly i will do that. But that is not the only solution. It would be nice if we can luch programs with out inheriting from explorer.exe. I saw some apllication from some trusted venders used to do so.. they dont load their application on explorer.

Well, that's the case. I have no clue about what you mean by "inheriting explorer"... If your application crashes, explorer doesn't crash. They are two independant things, so why would they interfere ? Unless maybe you are talking about something specific like a shell extension ?
|
|
|
|

yeah.. not exactly inheriting.. but all the applications in window by default load on explorer, some thing like child process of explorer. And my application is also doing the same. But i saw some applications like MacAfee client are independent.

Hi,
I want to create resizable propetysheet with watermark bitmap background.
Or a Header bitmap with colored background.
I am able to resize the proprtysheet but not header bitmap and background bitmap.
Please suggest some artical to do so.
|

|
|
CPropertySheet(
LPCTSTR pszCaption,
CWnd* pParentWnd,
UINT iSelectPage,
HBITMAP hbmWatermark,
HPALETTE hpalWatermark = NULL,
HBITMAP hbmHeader = NULL
);
See the parameters in bold. For setting the background you can override OnPaint message of your property sheet class
