Once again, I've got a problem with the app I'm developing. If anyone can help me figure out what I'm doing wrong here I'd be very grateful.
First, some background. I'm writing this in VB.NET, using Visual Studio 2010 Ultimate. The program creates a number of forms dynamically from information in a database table, laying out a few controls on each of the forms, and then presents them to the user as needed in response to user interactions with the program.
One of the types of controls I added to the forms a few weeks ago was the Windows Media Player, so we can have running video on any/all of the screens. At the time I added it, I was rushed for time and the COM+wrapper implementation of the WMP as a component was a bit on the opaque side when it came to creating instances of the player programmatically, so I cheated and dropped a player on the form that served as my base class, made it hidden and inactive, and only activated it when I needed a player on a descendant. Yeah, I know, inefficient and uses up memory even on the forms without video. I know. I intended to do it right later.
Well, this morning I finally got around to doing it right, mainly by figuring out what the hell I needed to do to retrieve the right OcxState for the player so my creation routine didn't crash out with a mystery message. Except...
Although the media player is there, it's got the video it's supposed to show loaded, the little play-position control thingy is progressing left-to-right on the control bar, and everything else claims to be hunky-dory -- nothing appears in the control. If I use the WMP context menu to zoom to full screen, I can see the video, but anytime I want to see it on the form, no dice. Now this was behaving properly when I was working with an instance put on the form at design time, so I'm pretty sure it's something inobvious I'm not setting properly at object creation.
I'm hoping someone here has a clue they can share with me... Thanks.
