Re: Re: How to capture screen under Win32?

I could be wrong, and probably am :), but I think GetDC is much likelier to be in GDI32 (the graphics engine) than user32.

I think your $screenshot handle is probably undefined.

Using a quickview program, in `USER32.dll`, it has `GetDC()`listed. In `GDI32.dll` it had stuff like `GetDCBrushColor` and some other various ones like that. Output from $screenshot handle from original code (before the `$screenshot->Call()` via Data::Dumper: `$VAR1 = bless( { 'dllname' => 'user32', 'dll' => 2011234304, 'proc' => 2011246207, 'out' => 1, 'in' => [] }, 'Win32::API' );` [download]	[reply] [d/l]

Cool... I told you I was probably wrong :) I just checked the MS docs, and getDC takes a window handle as an argument. Pass 0 to get the DC for the whole screen. And don't forget to call ReleaseDC, or bad things can happen... We now exit MS win32 api hell, and return you to your regularly scheduled perl programming :) -- Mike	[reply]
