Capt DLL problem.

[lolp1]

Hello,

I was recently messing with the captDLL and am having some problems. Every time I use it I get this error:

I am using V2 from here:

http://www.autoitscript.com/forum/index.ph...t=0&start=0

This is the example I am using. (What was provided)

; Capture full screen
; Fist parameter - filename, last - jpeg quality. 
DllCall("captdll.dll", "int", "CaptureScreen", "str", "dump_full.jpg", "int", 85)
; Capture given region
; Fist parameter - filename, next four: left, top, width, height. Last one - jpeg quality.
; Set quality to any negative number to capture into BMP
DllCall("captdll.dll", "int", "CaptureRegion", "str", "dump_partial.bmp", "int", 100, "int", 100, "int", 300, "int", 200, "int", -1)

Any ideas?

Did you open the dll?

$dll = DllOpen("captdll.dll")
DllCall($dll, "int", "CaptureScreen", "str", "dump_full.jpg", "int", 100)

Yes, same error.

You're using beta and the dll is in the same directory as the calling script?

It works fine here also.

You have forgotten to declare the calling convention (with "cdecl"). Later versions of AutoIt require that you do it.

It should look something like this: (Have not tested it myself since I'm to lazy to mess with the required .dll )

; Capture full screen
; Fist parameter - filename, last - jpeg quality.
DllCall("captdll.dll", "int:cdecl", "CaptureScreen", "str", "dump_full.jpg", "int", 85)
; Capture given region
; Fist parameter - filename, next four: left, top, width, height. Last one - jpeg quality.
; Set quality to any negative number to capture into BMP
DllCall("captdll.dll", "int:cdecl", "CaptureRegion", "str", "dump_partial.bmp", "int", 100, "int", 100, "int", 300, "int", 200, "int", -1)

I tested it and for me both ("int" or "int:cdecl") work with beta, thanks. Hopefully this solves lolp1's problem.

Correction: I just installed beta v3.2.3.6 (Apr17,07) and "int" gives me the same error as lolp1 but "int:cdecl" works perfectly.
