Description:
This DLL allows the programmer to take snapshots of the screen. There are three main functions:

License:
Free for non-commercial use. Contact me at rsf1000@gmail.com for a license.

Functions:
CaptureDesktop - Takes a snapshot of the entire screen. (In the next update, I will fix this so it actually captures the desktop window.)
CaptureWindow - This function is able to take a snapshot of the client area of a window! You can also use this as a faster method to saving screenshots of the game.
GetWindowHandle - Gets the handle of a window to be used with CaptureWindow.

Refer to the example game's comments to see how these functions work.

Sorry to tell you, but I can't really see much of a use for this. However, it's nice to see more people contributing to this section of the GMC.

I tried it... nothing ever happened :S

No file created D:

<{POST_SNAPBACK}>

Have you ever heard of screensavers? Many of them take a snapshot and then edit it, like mysterious in win xp. HiroLord, do you have windows xp, because I think microsoft fu**ed up visual studio 2005 on vista so that DLLs created with it dont work on xp.

Yes, I have heard of screensavers, but here is my point:

"CaptureDesktop" - ooohh!!! *Presses PrtScrn button*
"CaptureWindow" - ooohh!!! *Ctrl+Alt+PrtScrn*
"GetWindowHandle" - ooohh!!! *Types window_handle() into GM*

You are an idiot. Those are not at all how the functions work. First of all, window_handle() only gets the handle of the game window, not other windows. CTRL ALT PRINT SCREEN only takes a snapshot of a maximized window, so good try, you fail.

Edit: Why don't you try contributing something useful. After all, you are a "C++ Coder". After reading a few of your replies, all I see are third party tools that show the same information as task manager or by typing 'winver' into run ("oooh").

Congratulations on trying to annoy me. But supposedly like you said to me "you fail". And if you read my first post, I offered constructive criticism, and welcomed you to the section of the GMC dedicated to DLL creations. However, instead of accepting my welcome, you've more like spat in my face.

Also, I don't know what version of windows you are using, but Ctrl+Alt+PrtScrn take a snapshot of only the active window, not the maximised one.

Oh, and you can slag my System Information DLL all you want, because if you read other peoples' replies, you will see that it has one thing your DLL doesn't:

Thank you, and goodnight.

Edit: Oh, and explain to me the "third party" thing about my DLLs?

[HiroLord]

Yeah, i use Windows XP

I really wish I could use this

[retrogamer]

There are easy GML scripts to do most of those actions, HiroLord. It is pretty simple, you don't need a DLL for most of these.

Also, from the manuel:

Note that DLLs cannot be used in secure mode.

That might help.

Hiro, I fixed the bug! All versions of windows can now use this, sorry it took a while. And to clarify, you do need a dll for all of these functions. Gamemaker can only take a snapshot of the game window, not other windows.

arg, you're both wrong.
ctrl + alt+ prnt scrn doesn't do either of those things.
alt + prnt screen captures the active window/menu/taskbar.
using control in this sequence is completely useless.

Regardless, my dll doesn't use key combinations to capture the screen. It uses gid+. One more thing, if you try the example, run notepad.exe first because that is the window that I set it to capture. Or you can edit the example.

Thank you for making this! I have had use for this in the past, and I'm glad someone -finally- got around to making it

Yeah, go into the CaptureWindow and CaptureScreen scripts and change "CaptureWindowId" to "CaptureScreenId", it should work
for you then, oh, and by the way, nice ddl, minus the little script glitch you forgot to fix, but you should take care of that, cuz this is
pretty usefull for screensavers and other stuff, again, nice job!

[LehdaRi]

This seems to work on notepad only... I tried Paint, Firefox, IE and even CMD but nothing happened. Just with the notepad. :S

[fire_soul453]

Great dll. I love the CaptureDesktop. I plan I using this soon. I have a few uses for it.
