Hi all,

lets say i have this function in a ReadWrite.cpp file:

void CReadWriteDlg::OnButton4()
{
AfxMessageBox("test");
}

how do i call this function from a function in a different file altogether, say, SystemTray.cpp:

void CSystemTray::OnMyDeviceChange(WPARAM wParam, LPARAM lParam)
{
CReadWriteDlg::OnButton4(); //whats the correct syntax for this???
.
.
.
.
}

any help is greatly appreciated!

thanks!

If you work with Dialogs then have CWnd and handles. So it is right to use PostMessage with user defined messages ( ->RegisterMessage ). PostMessage is better then SendMessage because it puts the message in the internal message queue. Read the fine MSDN. Sleepy | :zzz:

I think it may be done by overriding CButton class then need to draw button yourself overriding DrawItem().

Use of SHFileOperation

use SHFileOperation instead of RemoveDirectory. This function will delete the directory event if there are contents in that folder.

This means that the dll does not have the debugging info.

It looks like all the dlls that get loaded when your app starts to me.

I see all that and more in the output window every time I run an app in the debugger.

What's the question?

Did you copy the 'stdafx.h' file to the new project folder?
