Hi.
I have discovered a problem with multithreading processes in my program. Here is an example.
- program starts
- CMyProgramApp::InitInstance() calls RestoreState() in CMainFrame()
- RestoreState() restores the windows positions via registry
- RestoreState() restores data (int, char, binary, etc) from registry to variables in CMyProgramDoc()
- RestoreState() calls a function in CMyProgramDoc() which begins a worker thread
- worker thread does some calculation
Problem: For some reason, I have found that if the calculation is big i.e. it takes a long time, the thread never gets closed and deleted.
The worker thread PostMessage main frame a message indicating that it is done. However, sometimes main frame never received the message!
-----
UINT WorkerThreadFunc(LPVOID pParam)
{
...
pWnd->PostMessage(WM_USER_WORKERTHREAD_CLOSED, 0, 0);
return 0;
-----
There is a handler in main frame to handle the message that class a function in doc to close the worker thread; however, I found that if the worker thread takes a long time to finish a calculation, main frame never receive or ignores the PostMessage.
The only problem I can think of right now is I am starting the worker thread too early. In other words, I should start the worker thread after the program has started and all window positions have been restored.
Do you see any other flaws? Please post.
Thanks,
Kuphryn

Okay.
Damn. The problem was not anything except bad debugging. I made a small mistake that caused a program loop inside the worker thread. The worker thread never PostMessage! It there is a loop that never exits.
The solution was to reset one of the variables I used inside the while look.
The breakpoint feature in Visual C++ is extremely useful!.
Special thanks to IndirectX of GameDev for breaking up the subject about breakpoint.

I have tutorials [part 1 and part 2] on this subject. Maybe a tutorial format will be easier for you to digest.

No, it's acceptable here to pimp your own stuff in your signature. Else I wouldn't be doing it.

I can't find how can I use WM_ONKEYDOWN or WM_ONSYSKEYDOWN when I 've somme buttons on my
application. If I erase them, it workds perfectly, but either not...
If I have buttons, they take the input focus, and I can't find the way to keep the focus on my
window

Hi people,
I'm trying to change the font used to draw in my view class, but there's something wrong. This is the code in my view's OnDraw handler:
CFont NewFont;
LOGFONT LogFont;
GetFont()->GetLogFont(&LogFont);
LogFont.lfWeight = FW_NORMAL;
NewFont.CreateFontIndirect(&LogFont);
I found this code in quite a few examples in forums, but the call to GetLogFont causes an assertion failure:
_AFXWIN_INLINE int CFont::GetLogFont(LOGFONT* pLogFont)
{ ASSERT(m_hObject != NULL);
return ::GetObject(m_hObject, sizeof(LOGFONT), pLogFont); }
I can't even figure out what the m_hObject is supposed to contain, let alone why it's NULL. Anyone have a clue?
Thanks a lot,
ren

The GetFont() call is returning NULL. This will normally only work if a call to SetFont() or WM_SETFONT message has already been done/sent to the window in question.

If i can't use CString in my non-mfc app then how do i use the AllocSysString?
Thanks

SysAllocString (and SysFreeString to free resources)

It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to.

Hi!
Is there a way to know if a mail program is present on a system and correctly installed. Because when I use the Windows MAPI functions, my program fails if there is no program set.
I'm programming in C-Windows.
Thks in advance!

You can check the following registry key to see if any profiles exist:
Win9X/ME:
Software\Microsoft\Windows Messaging Subsystem\Profiles
WinNT:
Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles

How can I write text and draw lines in a MS Word Application from an MFC Project without DOC/VIEW Architecture???

You might want to look at COM Automation. It's a lot of work to get your head round at first, but it'll do what you need.
A starting point would be in MSDN, under:
Platform SDK-->COM and ActiveX Object Servies-->Automation

Are there any specific precautions to using A2W? I am using it in a small piece of code that I have written and I have noticed that at times it appears that I have memory problems.
Any specific things that I need to watch for?

Acutally sorry I had forgotten to use SysAllocString!
