Use
<br />
dlg.m_ofn.lpstrFile=TEXT("DefaultFile.xxx");<br />
before DoModal()
Have a nice code day

CFileDialog dlg(TRUE,"bmp",NULL,OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,"Only BMP (*.bmp)|*.bmp|");<br />
<br />

I don't know, it is strange! 
A good thing could be add the flag OFN_FILEMUSTEXIST here:
CFileDialog dlg(TRUE,"bmp",NULL,OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,"Only BMP (*.bmp)|*.bmp|");
So you are sure that the file exist.
And I don't like very much
...,"Only BMP (*.bmp)|*.bmp|"
I prefere
...,"Only BMP (*.bmp)|*.bmp||"
Let me know
Have a nice code day

If lpstrFile is assigned a non-NULL value, so must nMaxFile also be used to indicate the size of the buffer pointed to by lpstrFile.
Why do it this way, however, when the constructor already has provisions for such?

That is what the third parameter of CFileDialog's constructor is for.

Then why bother with CFileDialog if you already know the name of the file?
Also, the filter should end with two ‘|’ characters.

A callback function is a normal function that the system calls when comes specified events.
An event could be a mouse click, or a tollbar botton click, ....
To link the event to the function it is used the MESSAGE_MAP
(usually in this macros are used the IDs of the objects that the user is using)
is it OK?
Have a nice code day

fisrt of all thanks for your patience,
for the first time i think i've understood whats a callback.
See here
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg,WPARAM wParam, LPARAM lParam)
as i've read,WndProc processes all the messages send by the applications. right? so a message "coming" makes an event which inturn calls this CALLBACK wndProc right? am i right?

Following is a funciton where I am calling a thread
void CMyView::OnInitialUpdate()
{
...
AfxBeginThread(Thread_ScanConnectionState, m_sComPort, THREAD_PRIORITY_NORMAL, NULL, NULL, NULL);
...
}
//Foll is the thread definition
UINT CMyView::Thread_ScanConnectionState(LPVOID pParam)
{
CString sComPort;
sComPort = static_cast<lpcstr> (pParam);
return 1;
}
The declaration of the thread in the class header of CMyView is as below.
UINT Thread_ScanConnectionState( LPVOID pParam );
I get the compilation error as given below
error C2665: 'AfxBeginThread' : none of the 2 overloads can convert parameter 1 from type 'UINT (LPVOID)'
c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\atlmfc\include\afxwin.h(4105): could be 'CWinThread *AfxBeginThread(AFX_THREADPROC,LPVOID,int,UINT,DWORD,LPSECURITY_ATTRIBUTES)'

while trying to match the argument list '(overloaded-function, CString)'
Please let me know the error.

Hi,
First: AfxBeginThread takes a static function pointer. Yours is not a static function. IOW, make Thread_ScanConnectionState static.
Second: In the func nody you typed 'static_cast(pParam)': incorrect.
The correct is:
sComPort = static_cast<cstring> (pParam);
Third: Do not do extra typing: AfxBeginThread's default parameters work fine.
You need not pass THREAD_PRIORITY_NORMAL or the NULLs.

Sorry, it seems the editor doesn't love static_cast's signature
