Thanks for suggestion. I have just done so. But I'm not sure that the answer to my problem is inside the WPF part. It can also be in the MFC one.

Hi, I'm integrating some some WPF controls into a MFC dialog box. One of the control is a media player that shows live video. The second one is a label that shows the current video time. What I need is to have is the label on top of the media player. The label should only display the time, so its background needs to be transparent. Right now, I have the video player running fine inside the dialog box, but I am unable to have the time displayed as I wish. It just overlap the video player. Both WPF components were creating by following instructions from this link. https://msdn.microsoft.com/en-us/library/ms742522(v=vs.110).aspx#hosting\_a\_wpf\_page\[^\] I try to set the label with a transparent background. timeLabel->Background = gcnew System::Windows::Media::SolidColorBrush (System::Windows::Media::Colors::Transparent); But the label background is shown black. I also try to set the Transparent flag of the MFC CDialog to true, but it didn't have any effect. How can I that fixed? Do I need to set up something special when I instantiate the WPF controls? Do I need to call some functions from inside the MFC dialog box? Thanks, Alain Migeon PS This question has also been asked in "C / C++ / MFC" forum.
