Procedure CaptureScreen(Left.l, Top.l, Width.l, Height.l)
    dm.DEVMODE
    srcDC.l
    trgDC.l
    BMPHandle.l
    srcDC = CreateDC_("DISPLAY", "", "", dm)
    trgDC = CreateCompatibleDC_(srcDC)
    BMPHandle = CreateCompatibleBitmap_(srcDC, Width, Height)
    SelectObject_( trgDC, BMPHandle)
    BitBlt_( trgDC, 0, 0, Width, Height, srcDC, Left, Top, #SRCCOPY)
    OpenClipboard_(#NULL) 
        EmptyClipboard_()
        SetClipboardData_(2, BMPHandle)
    CloseClipboard_()
    DeleteDC_( trgDC)
    ReleaseDC_( BMPHandle, srcDC)
    ProcedureReturn
EndProcedure

CaptureScreen( 0, 0, 800, 600)

Using the above code how would I save the picture from the clipboard?

Code: Select all

Procedure CaptureScreen(Left.l, Top.l, Width.l, Height.l) 
    dm.DEVMODE 
    srcDC.l 
    trgDC.l 
    BMPHandle.l 
    srcDC = CreateDC_("DISPLAY", "", "", dm) 
    trgDC = CreateCompatibleDC_(srcDC) 
    BMPHandle = CreateCompatibleBitmap_(srcDC, Width, Height) 
    SelectObject_( trgDC, BMPHandle) 
    BitBlt_( trgDC, 0, 0, Width, Height, srcDC, Left, Top, #SRCCOPY) 
    OpenClipboard_(#NULL) 
        EmptyClipboard_() 
        SetClipboardData_(2, BMPHandle) 
    CloseClipboard_() 
    DeleteDC_( trgDC) 
    ReleaseDC_( BMPHandle, srcDC) 
    ProcedureReturn BMPHandle
EndProcedure 
Width=800
Height=600
FileName$="C:\Test.bmp"
*DeskTop=CaptureScreen( 0, 0, Width, Height) 
CreateImage(DeskTop, Width, Height)
UseImage(DeskTop) 
StartDrawing(ImageOutput()) 
  DrawImage(*DeskTop, 1, 1) 
StopDrawing()

SaveImage(DeskTopSprite, FileName$ ,#PB_ImagePlugin_BMP )

you need to return your handle to the BMP then this will work

I kept everything (it happens when u have over 3gb webspace) and like to have access to ur files 24/7.....

the files were only public for a couple of hrs (3/4) the friendly peeps @ blitz irc told me about it....

edit: the final function is

Code: Select all

Procedure.l CaptureScreen(Left.l, Top.l, Width.l, Height.l)
    dm.DEVMODE
    srcDC.l
    trgDC.l
    BMPHandle.l
    srcDC = CreateDC_("DISPLAY", "", "", dm)
    trgDC = CreateCompatibleDC_(srcDC)
    BMPHandle = CreateCompatibleBitmap_(srcDC, Width, Height)
    SelectObject_( trgDC, BMPHandle)
    BitBlt_( trgDC, 0, 0, Width, Height, srcDC, Left, Top, #SRCCOPY)
    OpenClipboard_(#NULL)
        EmptyClipboard_()
        SetClipboardData_(2, BMPHandle)
    CloseClipboard_()
    DeleteDC_( trgDC)
    ReleaseDC_( BMPHandle, srcDC)
    ProcedureReturn BMPHandle
EndProcedure

Procedure.l SaveScreen(FileName.s,Left.l,Top.l,Width.l,Height.l)
    *DeskTop = CaptureScreen(Left.l,Top.l,Width.l,Height.l) 
    CreateImage(DeskTop,Width.l,Height.l) 
    UseImage(DeskTop) 
    StartDrawing(ImageOutput()) 
        DrawImage(*DeskTop,0,0)
    StopDrawing() 
    SaveImage(DeskTopSprite,FileName.s,#PB_ImagePlugin_BMP)
EndProcedure

SaveScreen("recdta\scr.bmp",50,50,300,200)

In no way am I trying to disrespect you.. you seem to have a valid and truthful reason for it being there.. so it was an honest mistake.. no worries. It would be a different story if you came and replied saying "yea hehe.. thats me!" then my post would have been to confront you and in a way disrepect you and let the right people know. But like I said.. you seem to be a respectul/honest person and I fully believe your statement about this. So no hard feelings?

Code: Select all

...
OpenClipboard_(#NULL) 
    EmptyClipboard_() 
    SetClipboardData_(2, BMPHandle) 
CloseClipboard_()
...

Do you really need to also save the screenshot to the clipboard?
