Hello there. In Windows, using RunRev's Shell command, I've been able to run ImageMagick via command line to perform a simple image conversion:

on mouseUp
put "convert c:\aPicture.jpg c:\aPicture.png" into switchCommand
get shell (switchCommand)
end mouseUp

Btw, I also tried:

on mouseUp
put "c:\imagemagick\convert.exe c:\aPicture.jpg c:\aPicture.png" into switchCommand
get shell (switchCommand)
end mouseUp

Both successfully converted the image. However, whenever I press the button to drive ImageMagick, the black Windows command line window appears for a split-second (on top of the RunRev stack), and then disappears.

Is there a way to either suppress or hide the Windows command line window, so that the user never sees it?

Thank you in advance,
Ron Toledo

Hi Ron,

just add this line:

Code: Select all

on mouseUp 
  ## This one:
  set the hideconsolewindows to true

  put "convert c:\aPicture.jpg c:\aPicture.png" into switchCommand 
  get shell (switchCommand) 
end mouseUp

Before you call the shell command, use the instruction:

Code: Select all

set the hideConsoleWindows to true

and... well, you can work out what it does

Wonderful!

Thank you both very much. I'm a ColdFusion developer, and have committed to learning Revolution as a new language. I continue to be wowed by Revolution's elegance, and this forum and your support makes it even better.

Have a great day,
Ron
