Whenever I check it, it is freeing only half of the allocated size. But it frees the whole allocated memory when I deallocate it at the time of terminating the application, not while 'm running the application.

How are you checking this? There's no accurate way that I know of.
Try this if you'd like:
MEMORYSTATUS OrigMemoryStat;
::GlobalMemoryStatus(&PrevMemoryStat);
TRACE(_T("********************************\n"));
for (int i = 0; i < 100; ++i)
{
HGLOBAL hGlobal = ::GlobalAlloc(GHND, 2000);
::GlobalFree(hGlobal);
MEMORYSTATUS MemoryStat;
::GlobalMemoryStatus(&MemoryStat);
TRACE(_T("********************************\n"));
TRACE(_T("** Delta dwAvailPhys %li Bytes\n"), (long)MemoryStat.dwAvailPhys - (long)OrigMemoryStat.dwAvailPhys);
TRACE(_T("** Delta dwAvailVirtual %li Bytes\n"), (long)MemoryStat.dwAvailVirtual - (long)OrigMemoryStat.dwAvailVirtual);
}
TRACE(_T("********************************\n"));

Ok, I figured out the problem. Once I allocate the memory, I am saving data into the variable by calling another function, in this process I am allocating more memory to another variable to hold a bitmap data, which is not being deallocated later and its piling up.

How are you doing this?

wrong, white is RGB(255, 255, 255)

I am wondering if anyone knows a reliable way using GDI to detect whether an HFONT has unicode support?
|
|
|
|

Does the GetFontUnicodeRanges() API help to determine Unicode support for a font?
CClientDC dc(this);
CFont font;
VERIFY(font.CreatePointFont(120, _T("Arial Unicode MS"), &dc));
CFont* def_font = dc.SelectObject(&font);
DWORD dwGlyphSetSize = ::GetFontUnicodeRanges(dc, 0);
GLYPHSET *pGlyphSet = (GLYPHSET *)new BYTE[dwGlyphSetSize];
::GetFontUnicodeRanges(dc, pGlyphSet);
delete[] (BYTE *)pGlyphSet;
dc.SelectObject(def_font);

Thanks Mark
I looked into that API call, however the other stipulation that I forgot to mention  is that it has to work with windows 98. Unfortunatly that call only works for 2000 and up.
If there is any other way that you know of?
Thanks again Mark

Hmmm, maybe this KB article will help: Unicode support in Windows 95 and Windows 98[^]

I have a DefWindowProc() function to catch unhandled messages. This function returns an LRESULT. I have a switch statement and in some cases I call CWnd::DefWindowProc(). So I simply return the result of the call to CWnd::DefWindowProc(). In other cases, I handle the message.
What should the value of LRESULT be when I handle the message?
|
|
|
|
|
Depends on the message. The documentation will tell you if the message needs a certain return value. If it does not then simply return zero.

Per MSDN:
The return value is the result of the message processing and depends on the message sent.

Is there a way to make the Save File Dialog have an uneditable directory path or do I have to create a dialog from scratch to do this?
|
|
|
|
|
What does the word "Uneditable" mean?
|
|
|
|
|
So that they can not change the directory that they are in
|
|
|
|
|
Is this[^] what you want?
If not, there articles on how to modify the file dialog found here[^]
You may be right
I may be crazy
