Built form without see it on the screen

[Giuseppe Belziti]

It happens with slow computers that when we build a form it appears slowly. We can build the form in memory without see it on the screen and then see full display once built?

Sure, that's easy! {smile} Just use PAGE to set the active page to a different page than the visible page. Then, print to the active page (which is invisible), until you're done. Finally, use PCOPY to copy it the visible page, and use PAGE to set the active page back to the visible page.

Best regards,

Thanks Bob for the excellent suggestion.
One other thing: when a program starts, before you run some command it opens a window. We can avoid that opens the window before you run some commands?

#CONSOLE OFF at the beginning will stop the Console window from opening.

in this way then I can not open the Console. I would lock the console to create the page, open the console and display the page. In order not to see the console while I'm creating the page.

Maybe you can use console off as suggested and then on demand use AllocConsole() and FreeConsole() API ??

And I would not spend any time trying to make it work, either.

I seriously doubt the PB/CC compiler was designed to handle any "CONSOLE..." commands for consoles it does not create itself, which is not unreasonable at all IMO.

You may be right but since we are talking about 3 std handles applied to the app i assumed no problem.
Anyway, "not run" does not help much..

sorry, I meant nothing happens, I applied the suggestion but the window is hidden and not displayed.

Not really. In PB/CC, uses of STDIN, STDOUT or STDERR refer to the handle AT THE TIME THE PROGRAM STARTED, NOT WHAT IT CURRENTLY IS. That is, any in-process redirection is igored. Except for STDERR, which is always the console and cannot be re-directed intrinsically... which is why this demo exists:
