Okay I read that documentation and I played around with stuff, but I'm really not sure how to create m_ofn and then use its member functions.

Thanks a very good example thanks. Should I just rely on example code and creating classes and objects manually rather than going through the class wizard?

If it is just a simple class, by all means you can do it manually. If you are creating dialog classes or any other types that deal with the windows interface, the class wizard is better and safer.

you can use this little piece of code :-
CFileDialog m_DlgFile(TRUE);
if(m_DlgFile.DoModal()==IDOK)
{
MessageBox(m_DlgFile.GetPathName( ),"selected File Name");
}

I'm trying to understand how it's done automatically when you use the wizard, so I searched for CFileDialog but I can't find it anywhere in my application. I started a MFC single window app that has the open file functionality already working. How is that working?

The CWinAPP class do that for you, see this Message Handller defination
BEGIN_MESSAGE_MAP(CSdiApp, CWinApp)
ON_COMMAND(ID_APP_ABOUT, OnAppAbout)
ON_COMMAND(ID_FILE_NEW, CWinApp::OnFileNew)
ON_COMMAND(ID_FILE_OPEN, CWinApp::OnFileOpen)
END_MESSAGE_MAP()

Here's what I wrote so I know this part works. I created a new class "ButtonP" which has a base class of CFileDialog, but could I have just created an object of CFileDialog instead? Also I wanted to create an "on button pressed" function but I didn't know how.
void CMy3daudioDlg::OnBrowse()
{
CDialog::OnInitDialog();
ButtonP open(TRUE);
CString mystring;
open.DoModal();
mystring = open.GetPathName();
AfxMessageBox(mystring);
}

Does this imply that you are working on an SDI or MDI application?

Neither actually, it's a dialog based program because there's only a couple things the user can do.

So is CFileDialog what you are looking for then?

I want to serialize the CGridCtrl in order to use Keith Rule's "Simple and Easy Undo/Redo". Can anyone give an example of a Serialize routine implemented in CGridCtrl ?
Thanks.

The documentation for WritePrivateProfileString() clearly states that if the lpKeyName parameter is NULL, the entire section, including all entries within the section, is deleted.

Hi all!
I have a thread problem in the following code:
(This is not the complete code..)
Somewhere in a function i have the following implementation:
/*****************************************/
// Start of thread
HANDLE hThread = CreateThread(...);
// Wait until thread ends
WaitForSingleObject(hThread, INFINITE);
...
/*****************************************/
// Thread procedure
DWORD WINAPI ThreadProc(LPVOID lpParam)
{
// My code
......
......
SendMessage() <--- The system right here is deadlock (***)
return 0;
}
(***)
The SendMessage() function sends message (LVM_INSERTITEM) to a list view control of the window that stared the thread.
The problem is that I want the SendMessage() function to work, without removing the WaitForSingleObject() function, or any other "wait" function it might need to be replaced.
Thanks for any reply!

This will never work !! I suppose the function which creates the Thread is not in another thread than your application ? Thus your application will freeze because of the WaitForSingleObject call. And because of that, it cannot process messages anymore (so it will not respond to user events neither).
It is not a good idea to call WaitForSingleObject in the main thread. A better idea would be that, when your secondary thread finishes, it sends a message (an owner defined message) to the main window resulting in calling a specific function that will manage every that needs to be done when your thread finishes.

Hello,
What you are doing is asking for trouble! The rule of thumb is: never touch the GUI from your worker thread!!!!
If you really need to do this, try the following: use PostMessage() instead of SendMessage().
If you really need to wait for the thread to finish, use MsgWaitForMultipleObjects() instead of WaitForSingleObject(). This way, your app won't freeze because it will process messages.
Hope this helps.

how to develop an assembler in C++
the idea that i got was
__asm {
}
but do anyone have any idea more abt that?

 This sentence means nothing ! For me, assembler is a low-level language. So, how can you 'develop' a language ??
Otherwise, yes with __asm you will be able to use write assembler code inside your C++ code. But that does not mean you are developping an assembler.
