Avoiding 'Flicker' on Startups of EXEs?

[pt777]

I've tried to avoid bothersome (app startup) flickers by:
placing commands _screen.visible=.F. and _screen.lockscreen=.T. immediately in the main.prg(s).

This workaround helps but does not completely stop the bothersome startup blinking/flickering that occurs

... that is to say, VFP has a visible screen during startup of exes that I'm trying to make invisible BEFORE main.prg if feasible.

Thanks in advance for any suggestions or feedback!

If you don't have one, create a config.fpw file and put

[COLOR=blue]SCREEN = OFF[/color]

at the top of the file.

This will prevent the behaviour you describe - at a suitable point in your main.prg, put

[COLOR=blue]_SCREEN.Visible = .T.[/color]

to enable the application to be visible.

There are numerous threads on the use of config.fpw in this forum, so a keyword search should find what you need.

Thanks Chris,
I had no idea I could use a config.fpw file in my exe directory (till I read up on it).
That fixed it.

I'm also using SCREEN = OFF/_SCREEN.Visible = .T. with success. It works fine, but still some flickering persists. Before DO MyMenu.mpr in my main program a system menu is visible for a moment. Is there any way how to avoid this.

Put

[COLOR=blue]_SCREEN.Visible = .T.[/color]

after

[COLOR=blue]DO MyMenu.mpr[/color]

and before READ EVENTS so your app is initialised before it becomes visible.

Alternatively, put

[COLOR=blue]SET SYSMENU TO[/color]

at the start of your main.prg

ChrisRChamberlain and torturedmind

you both are perfectly true. How could I miss it. It was o drop out. I am using "if version(2) <> 0" clause in programs, so I don't see normal start of application so often and some flickering doesn't bother me so much. Only this thread remember this..

Thank you and take my excuse for stupid question. Tom

Hi,

Maybe this thread may help you with all comments there about "clean" start of VFP program and closing behaviour:
