You will have to be more specific.
BOOL CALLBACK My_EnumWindowsProc(HWND hwnd, LPARAM lParam)
{
__asm
{
...
}
}

i add an section to my exe file, then my cods should be asm language.
in code of this section i call myFunc. one of parameters of this function is address of a callback function.
callback function is defined end of asm code (before end of asm block), and i calculate address of this function to send to myFunc function.(correctly)
but my exe encounter "Don't send" error.
how do i return of callback function to main address of code?
for example to call "ExitThread" i return of thread to main address of code
_asm<br />
{<br />
....<br />
push addressOfCallbackFunc<br />
call myFunc<br />
....<br />
jmp End<br />
<br />
CallbackFunc:<br />
....<br />
ret
<br />
End:<br />
}

hi
I am using CImage Class(ATL) to Load and Save PNG's.There are some memory leaks with the class.
Are there any alternative image libraries like CxImage etc which can perform the same functionality??

You was used of CImage class or CXImage calss however you can use of GDI+ for load,save and.. other operations on files

Really? Do you have an example of code that leaks in the CImage class?
Alot of people use that class and I'm sure they'd like to know.

GDI+
Kinda slow, and the interface is kinda clunky but it gets the job done

I have already included the include file and the lib file in the project. Then also it is showing this error.
Can you please tell me why ?
I have just migrated from VIsual studio 6.0 to visual studio 8.0 that's why this problems are coming in manier projects.
Thanks for prompt reply.

LPCTSTR lpszPathName;
CFileDialog fileDlg(TRUE);
fileDlg.m_ofn.lpstrTitle="Open";
fileDlg.m_ofn.lpstrFilter="BMP Files(*.bmp)\0*.bmp\0\0";
if(fileDlg.DoModal()==IDOK)
lpszPathName=fileDlg.GetPathName();
else
return;
CFile file;
if (!file.Open(lpszPathName, CFile::modeRead | CFile::shareDenyWrite))
{
AfxMessageBox("File open failed");
return;
}
Is there something wrong in the codes up?
Thankks~

 The messagebox appears~

Did you use of debugger for see value of lpszPathName is it correct and valid?

I want to open a file named "aa" in path C:\Documents and Settings\示例图片\aa
I saw the debugger and the content is "C:\Documents and Settings\示例图片\葺葺葺葺葺葺葺葺葺葺葺葺?"
Why~?

Here is an example of opening a file open dialog box - hope this helps
void CFileProc1Dlg::OnOpenBtn()
{
// TODO: Add your control notification handler code here
this->UpdateData();
CFile f;
char strFilter[] = { "Files (*.dat)|*.dat|All Files (*.*)|*.*||" };
CFileDialog FileDlg(TRUE, ".dat", NULL, 0, strFilter);
if( FileDlg.DoModal() == IDOK )
{
if( f.Open(FileDlg.GetFileName(), CFile::modeRead) == FALSE )
return;
CArchive ar(&f, CArchive::load);
ar >> m_sample;
ar.Close();
}
else
return;
f.Close();
this->UpdateData(FALSE);
}
