You need to synchronize the main thread (that's the one the CMainWnd is running in) with the other thread. In addition, have you at any point told the other thread to exit? If not, it won't, until the application exits.
Without seeing code, it's difficult to say much more.

i think your answer lighten me up. after creating main thread creating the thread ,i used closehandle();do you me if i hold the handle of the thread, the problem will not hanppen? aslo there is no more synchronize work needed?

A thread that does one thing then exits its thread function
The auxiliary thread exits of its own volition. The main thread can then check that the thread has exitted using the GetExitCodeThread[^] function (the functions shows a thread exit code of STILL_ACTIVE if the thread hasn't terminated), or can wait for the thread to exit using the WaitForSingleObject[^] function, using the thread handle as the handle to wait for (a thread's handle is set when the thread exits).A thread that does many things in a loop
In this case, you need some way of telling the thread that it's time to exit. In general, you could use a boolean flag that the thread can check each time round the loop (use InterlockedExchange[^] to set the flag from the main thread) or you could use an event[^] - the main thread would set the event to indicate that the other thread should exit, the other thread use WaitForSingleObject to see if the event's been set). In either case, the main thread would notify the other thread that it's time to exit, then wait for the thread to exit using WaitForSingleObject.
Use the appropriate pattern (I suspect it's the second from what you've said) when the thing that created the thread (your cmainwnd?) is destroyed.

You will have to choose CEditView instead of CView for the Application to support editing by default. Either create a new project and from "Generated Class" option, choose CEditView or CRichEditView instead of CView or manually rename CView References in your project to CEditView then it should work fine.
If your question is something else, please mention it clearly.

If the application has to support MFC choose either "MFC in a Shared DLL" or "Use MFC in a static library" from project properties.

I'm doing a project. It's working fine until it tries to open a file with a Chinese character in its path.
CFileDialog ImportDlg(TRUE,NULL,NULL,OFN_OVERWRITEPROMPT,_T("text Files (*.txt)|*.txt||"));
int iResult=ImportDlg.DoModal();
CString str=ImportDlg.GetPathName();
I think it works if I set the character set to Unicode set. I'm just wondering why it gives me question mark for the Chinese when I switch to MBCS set?

I guess you a haven't installed support for Asian languages in your OS.
Switching to Unicode should show you the same question marks.

Actually I do installed support for Asian languages, and it does show this Chinese in Unicode set. That's why I'm wondering.
|
|
|
|

Ok. In that case you could try to dump the data into a text file and open the text file.
It could be that the characters are not showable by the viewer.
Make sure you write these 3 hex. characters at the begining of the file.

Check the thread addressing the similar problem [^]
Since this is a non-Unicode application, you need to make sure that your "Language for non-Unicode programs" is set to Chinese (Simplified) and reboot. It then should work. (If you are on an English os and running a language pack, changing to the language pack does not automatically change the "Language for non-Unicode programs". This is done manually).
To make this change on Vista, see:
http:
IMO, it's better to stick with UNICODE for this kind of complex languages like Japanese and Chinese.

I have an 3 rd party API that will a fill a buffer of type LPSTR,
This buffer is actually in picture format, i have to convert make this appear in a CStatic control.
what i have:
BYTE pBuffer;
HDC hDC; //HDC handle for the CSttaic Control
API will fill this pBuffer
(LPSTR)pBuffer
I have to make this pBuffer to appear in picture format in CStatic control.
Would apprecaite any help.

What do you mean with 'in picture format' ?

This "pBuffer" i can save it as a Bitmap format like this.....
But i want to draw this pBuffer into a CStatic without converting to Bitmap...
CFile file;
CString strTemp;
char szTemp[MAX_PATH];
char *pDot;
GetModuleFileName(AfxGetInstanceHandle(),szTemp,sizeof(szTemp));
pDot = strrchr(szTemp,'.');
*(pDot+1) = 'B';
*(pDot+2) = 'M';
*(pDot+3) = 'P';
strTemp.Format(szTemp,GetTickCount());
file.Open(strTemp,CFile::modeCreate | CFile::modeWrite);
file.Write(pBuffer,dwSize);
file.Close();
|

According to your answer to CPallini, your buffer contains a BMP file. So, wiki[^] should contain all the information you need to access the pixel data. Also look for BITMAPFILEHEADER, BITMAPINFO and such structures in MSDN, these should help too. You could for example use CreateDIBSection[^] to get a HBITMAP from your data and use it to feed it to a picture (static) control or draw it yourself.

Hello,
Please any one tell me where i can get message IDs for registered activex controls?
I want to automate MSFlexgrid control or MSdatagrid control using Perl. This requires sending message to those controls. But I could not find any document containing grid control messages. I could get Message ID s of most of the controls (commonly used) in winuser.h and commctrl.h. Thank you in advance.
