I'd like to write a program to automate some screenshotting I'd like to do which is basically impossible to perform manually.
Anyone know how to do this?
I know there are programs that exist for screen recording, but none I've found are ideal, and a programmatic solution would provide me with an ultimate degree of flexibility.



None.

If you use GDI you could use GetDC(NULL); to get a handle for the entire screen... then just use BitBlt or GetDIBits to copy the data. GetDIBits is probably more useful because it gives you the raw data in a buffer so you could just dump it into a file or something. (BitBlt copies it to another dc thingy.)

I invite you to try out the map I modified. I don't have the creativity to create maps from scratch, but I do have the know-how to modify existing ones; my project is to tweak community campaigns (specifically those with errors—to make them playable.

Ultraviolet shouted: Mr.BurnLiquid actually yeah though I wasn't really saying it to narc on you. It just caught me off guard because I don't usually see it (because it's against the rules) "The avatar may not be bigger than 150x150 pixels". Kinda silly that it relies on users to be well behaved rather than just limiting the dimensions on uploads :lol:
Now that I wanted to change my avatar, the error image is showing up, haha.

Mr.BurnLiquid shouted: Ultraviolet Thanks; I'm new to the site and a Spanish speaker. I must have missed the part where it was prohibited—I'll change it now.
I invite you to try out a mission I'm modifying from *StarCraft Reversed*; I'm trying to make it more playable and challenging.
