Draw and save window without showing

[Marc Vanzegbroeck]

Hi,

For a documention-program that create excel-files with drawings I open a window, draw lines en text on in and save it to a bmp-file to create bmp-files.
The program show it on the screen. Is it possible to do this without showing it? Sometimes, I want to create more then 10000 BMP-files, and I think showing them slow down the generation.

I use now something like this for each file in a loop:

Code: Select all  Expand view

  DEFINE WINDOW sWnd TITLE 'SCHEMATIC : '+infoall->filenaam FROM 0,0 TO 416,640 PIXEL BORDER NONE NOSYSMENU NOICONIZE NOCAPTION

   sWnd:bPainted  := { || _toonds(vnr,vnrvar)}

   ACTIVATE WINDOW sWnd

   sWnd:SaveToBmp( alltrim(infoall->voorbeeld) )
   sWnd:end()
 

The function _toonds(vnr,vnrvar) drow text, lines, polygons,... on the window.

Thanks,
Marc

Marc,

You may not need to create a window everytime, and simply reuse the existing one, so the whole process will speed up
