I have an outlook plugin, in which I load winform usercontrols in custompane.When user tries to upload a file to the server, I want to show progress of the upload using a progress bar shown in the center of the pane, with rest of the pane area darkend but still tranparent to some extent.Here is a screen shot to give an idea of the UI.
So, how do I make background of a winform usercontrol partially transparent.
