I have this modeless MFC dialog which embeds an Internet Explorer web browser control. The control is derived straight from CWnd with ActiveX wrappers generated by Visual Studio, and I map it to the CDialog using only a "DDX_Control(pDX, IDC_EXPLORER, m_explorer);" I have 2 problems. Problem #1: Being modeless, I start and stop the di...
I need to update a combobox with a new value so it changes the reflected text in it. The cleanest way to do this is after the combobox has been initialised and with a message. So I am trying to craft a postmessage to the hwnd that contains the combobox. So if I want to send a message to it, changing the currently selected item to the n...
Since our switch from Visual Studio 6 to Visual Studio 2008, we've been using the MFC90.dll and msvc[pr]90.dlls along with the manifest files in a private side-by-side configuration so as to not worry about versions or installing them to the system. Pre-SP1, this was working fine (and still works fine on our developer machines). Now tha...
I would like to be able to display some dynamic text at the mouse cursor location in a win32 app, for instance to give an X,Y coordinate that would move with the cursor as though attached. I can do this during a mousemove event using a TextOut() call for the window at the mouse coordinates and invalidate a rectange around a stored la...

When I'm initializing a dialog, I'd like to select one of the radio buttons on the form.

How can I select one of the several radio buttons? ...
Hello. I'm trying to implement some drag and drop functionality for a material system being developed at my work.

We've got some in-house applications built in MFC, with OpenGL drawing routines. They all use the same code to draw on the screen and either print the screen or save it to a JPEG file.

When that number is edited, I would like to act on the change, and then replace the caret where it was before I acted on the change - if the user was just before the "." in "35.40", I would like it to still be placed before the dot if they chan...
I have an installation program (just a regular C++ MFC program, not Windows Installer based) that needs to set some registry values based on the type of Internet connection: broadband, dialup, and/or wireless. Right now this information is being determined by asking a series of yes or no questions. The problem is that the person doing ...
We have multiple MFC apps, which use CMutex( false, "blah" ), where "blah" allows the mutex to work across process boundaries. One of these apps was re-written without MFC (using Qt instead). How can I simulate the CMutex using Win32 calls? (Qt's QMutex is not inter-process.) I prefer not to modify the MFC apps. ...

What experience have you had with introducing a Ribbon style control to legacy MFC applications? I know it exists in the new VC2008 Feature Pack, but changing compilers from VC2005 is a big deal for our source base and integration to our environment, Intel FORTRAN, ClearCase, many 3rd libraries. There are quiet a few different commeri...
