Anyone else unable to print bitmaps on docs sent to a printer?

Question

Is anyone else having trouble getting bitmaps to print on documents sent to a printer? I was working on some code yesterday, and it was working just fine. This morning however, it simply stopped working, without making any code changes (was continuing my validation testing). I went back to some older projects that use the same method for printing and now they aren't working either. I have about 5 or 6 applications which perform a similar print operation, and every one I've tested seems to no longer be working. I'm beginning to think something changed in the OS, as these applications which have been working reliably for years just stopped working today. Using CDC for printing, with a bitmap included as a resource in my project. Here's the code: CBitmap BmpCusomterLogo; CDC MemDC; // Load the bitmap from the resource BmpCusomterLogo.LoadBitmap( IDB_BITMAP1 ); // Create a memory device compatible with the above CPaintDC variable MemDC.CreateCompatibleDC( pDC ); // Select the new bitmap CBitmap *BmpPrevious = MemDC.SelectObject( &BmpCusomterLogo ); // Copy the bits from the memory DC into the current dc pDC->BitBlt(1480, 400, 1800, 364, &MemDC, 0, 0, SRCCOPY ); // Restore the old bitmap pDC->SelectObject( BmpPrevious );

Answer 1

Seems like a Windows update ruined your code. SelectObject() fails here. Uninstall KB5000808 or KB5000802. Since most applications print their images just fine, I wonder how on earth everybody sends images to the printer?

Hi HenryShawn,

You can try to delete the .obj and .vs folders, then try to re-build your project.

I have the same problem, thought something was wrong with the printer drivers after the update but then I tried printing to pdf and the same problem was happening.
I also tried running the same exe on a machine that wasn't updated and there it worked fine, the winspool.dll might be messed up or there is an OS level problem.

This is likely to be caused by a windows update.
Have a look at https://learn.microsoft.com/en-us/answers/questions/335604/known-issue-unexpected-results-when-printing-from.html

It seems to be working now for me, I'm not sure which windows update fixed it works fine now.
