I am using LoadBitmap(hInstance,"bitmapname"); to load bitmap resources. I am trying to do this in the WM_CREATE: case of a child window. I get a NULL back from the function. When I move the LoadBitmap up to the parent's WM_CREATE: it works fine. I've tried setting the segment attributes to preload nondiscardable but to no avail. | Jack A Zucker {cwjcc,pyramid,decvax,uunet}!jaz@icd.ab.com | | Allen-Bradley Company, Inc. or ICCGCC::ZUCKER | | 747 Alpha Drive | | Highland Hts., OH 44143 Phone(216) 646-4668 FAX: (216) 646-4484 |

To load the DLL I use: hLibrary = LoadLibrary("d:\\windev\\jaz\\palette\\bitmap.dll"); To load the bitmap I say: hBitmap = LoadBitmap(hLibrary,"Pencil"); /* where pencil is the resource */ Once again, The LoadLibrary() and LoadBitmap() only work when done in the parent window. When called from the child's WM_CREATE: they return NULL. Unfortunately this is not mentioned in any of the SDK documentation, nor is it mentioned in Petzold's book. Am I doing something dumb or is this just a poorly documented feature ? | Jack A Zucker {cwjcc,pyramid,decvax,uunet}!jaz@icd.ab.com | | Allen-Bradley Company, Inc. or ICCGCC::ZUCKER | | 747 Alpha Drive | | Highland Hts., OH 44143 Phone(216) 646-4668 FAX: (216) 646-4484 |
