HI there, i've some major problems with my multimedial applications and the c++builder. Firstofall I'm searching a component (collection?) that is a progressbar whos background and foreground can be customized bitmaps - so I an design it like a blue tube which becomes a orange tube, when the position steps... Also a bitmap-trackbar is searched with full transparency bar (not like the LMD-Trackbar), because I want to design the thumb like an Ending of a Line and the Line (A TShape?) should indicate the Position. And there are two trackbars directly under each other, so I can simulate a "Begin-End-Positioner". To draw the Indicator-shape, the Trackbar has to be transparent... The Trackbar of LMDTools isn�t that transparent andif I use a black width=1 panel instead of a shape, because panels are always in front of tlmdcontrols, The Repainting won�t work (The thumb bitmap is there several times, it won�t be erased correctly...) The Trackbar of the "CoolComponents" also not work, because, the Thumb-Bitmap was cut, when it arrives at max or min position and there aren't any propertys to define a greater border... And the greatest Problem: In combination with Quicktime the Refreshing and MEssaging is miserable. If another window covers the Form and the quicktime movie, only parts of the form are repaintet, the movie not. I don't know exactly if the movie got a message to refresh? Is there anybody who has build a quicktime app with refreshing and without trouble? I trie to make updatemovies, moviestask, Handle WM_WindowPositioned, make COver and UncoverProcs... nothing works properly. Is there any window-Message that comes to the form, if another windows covers the form`and I can handle it to manually repaint? I would be very thankful, someone could help me, best regards, Bjoern M. Albrecht
