Hi

I am using dibapi32 to create an image from a form - it work beautifully with the following code but there is one problem it doesn't save the file automatically - the operator has to press save - that's not what i want - any ideas how to save the image automatically ?

*FORM/SCREEN CAPTURE TO BMP FILE:
*!* make FoxTools available
SET LIBRARY TO c:\global\FoxTools.FLL ADDITIVE
*!* make the class library available
SET CLASSLIB TO scrnprnt.vcx ADDITIVE
oCap = NEWOBJECT("capturescreen", "scrnprnt") && Create instance of Screenprint



*!* Capturing the active VFP form
lnRetVal = oCap.CaptureForm( "file.bmp" )
release oz2W
return
* calling
*=printscr()


function printscr()

DECLARE INTEGER GetDesktopWindow IN Win32api

DECLARE INTEGER PrintWindow IN DibApi32 ;
INTEGER HWnd, ;
INTEGER fPrintArea, ;
INTEGER fPrintOpt, ;
INTEGER wxScale, ;
INTEGER wyScale, ;
STRING @ szJobName

LOCAL nRetVal,cJobName && title you want to show when printing

cJobName = 'Current Screen' && or whatever - this could be passed in as a parameter, also.

nRetVal = PrintWindow(GetDesktopWindow(),1,1,0,0,@cJobName)
IF nRetVal != 0
IF nRetVal != 6 && 6 = User canceled printing
MESSAGEBOX("Unable to print the window" + chr(10) + ;
"See System Administrator " + STR(nRetVal),48, ;
"")
