I've got a fairly large MFC application that has just been migrated from VS6.0 to VS2008. It was a pretty painful process, but now I'd like to explore any managed-code options that may be available. I was able to successfully build the project using the /clr switch which seems to give me access to managed types. I'd like to know if con...
I am using the MFC class CSocket. Nothing complicated - open a connection to a server and send a short message. The code works fine when I link with MFC in a DLL. However, the call to CSocket::Create() crashes when I link to MFC in a static library. I would like to use MFC in a static library since it simplifies distribution. ...
I need to create a custom control to display bmp images with alpha channel. The background can be painted in different colors and the images have shadows so I need to truly "paint" the alpha channel.

Hi I have a CListCtrl object in my C++ MFC app for Windows Mobile 6. When I call listctrl.GetNextItem(0, LVNI_ABOVE) I should therefore get back -1 (no item above first item), but if (and only if) the list has exactly one item, the call returns 0, even though MSDN says "The specified item itself is excluded from the search". Is this a k...

Hi all, I am trying to create a control that implements the per-pixel alpha blend while painting a 32-bit bitmap. I extended a CWnd and use static control in the resource editor.

In MFC, a CListBox has a "disable no scroll" property. When you set it to true, the vertical scrollbar is always there, no matter how many items you have. How can I do the same thing with CListCtrl? ...
I have a MFC application in which I want to add internationalization support. The project is configured to use the "multi-byte character set" (the "unicode character set" is not an option in my situation).
