It's fairly simple, just pass the reference to the main form to the modeless form. Something like class MainForm : Form { public void ShowForm() { ChildForm f = new ChildForm(this); f.Show(); } } class ChildForm : Form { MainForm mainForm; public ChildForm(MainForm f) { mainForm = f; } void SomeFunc() { int data = mainForm.data; } } Regards Senthil _____________________________ My Blog | My Articles | WinMacro

The following code opens files with .wav extension Modify it as per ur need. void CMyProjectView::OnFileOpen() { CFileDialog cfd(TRUE,".wav",NULL,OFN_FILEMUSTEXIST|OFN_PATHMUSTEXIST,"WAV File(*.wav)|*.wav||",this); cfd.DoModal(); } ...Avenger Remember... testing & debugging are always part of programming ...so exterminate those stinking bugs

Did you know that you could modify your original response instead of creating more? "The pointy end goes in the other man." - Antonio Banderas (Zorro, 1998)

I suggest you to take a luck at example from “msdn” documentation “MTMDI” that demonstrates an MFC User Interface Thread. For avoiding potential problems when programming multithreaded applications you need to respect some rolls or programming tips that is also described in “mfc” documentation. Ex: - You can't have two threads manipulating the same object.., if you need this you need to protect such access with appropriate Win32 synchronization mechanisms... - A thread can access only MFC objects that it created, a worker thread cannot perform a calculation and then call a document’s “UpdateAllViews” member function to have the windows that contain views on the new data modified, because the map from CWnd objects to HWNDs is local to the primary thread. There are several ways around this problem: you can pass individual handles (such as an HWND) rather than C++ objects to the worker thread, or you can create new user-defined messages corresponding to the different tasks your worker threads will be performing and post these messages to the application’s main window using PostMessage. If this little help is not enough for your problem send me a sample of your code and I will help you. CC.
