xp-style manifest and HBITMAP 'flickering' (vc++ 6)
Posted on 2006-07-20
hi, i'm new here. hope someone can help.
i'm using vc++ 6 for lots of projects.. mostly dialog based tools and apps.
a problem i've had for a long time is, if i add an xp-style 'manifest' sheet for my dialog controls, the app displays the new style controls ok, but my bitmaps are 'flickering' whenever i use redrawwindow(). yet if i remove the xp style again, the problem doesn't occur.
the problem is happening with applications that use HBITMAP handles that are redrawn around every 1/25th of a second with a timer.. for special effects, etc.
the flickering looks like interlaced frames.. making large parts of the bitmap 'transparent'
like i say.. there's no problem without the xp-style manifest.. so what's causing it?
