 |
|
I have a bitmap in the RES file for my component. I load the bitmap with
the following code:
if ( this->ComponentState.Contains(csDesigning) )
this->FScrollDown->Glyph->LoadFromResourceName((int)HInstance,
"SCROLLDOWN");
I needed the if csDesigning because at design time the HInstatnce refers to
the res of the component. At runtime this causes an error "Resource
"SCOLLDOWN" not found"
I expected the bitmap to be streamed for me but that didn't work. At
runtime there is no bitmap.
Where do I save the bitmap to? Where do I locate the code?
Thanks.

You are using the wrong HInstance value when calling LoadFromResourceName().
You need to use the FindClassHInstance() function instead, ie:
FScrollDown->Glyph->LoadFromResourceName(FindClassHInstance(__classid(TMyCom
ponent)), "SCROLLDOWN");
This way, you also don't need to check the csDesigning flag at all, either.
