Blank white window when the .exe starts . How can I make a white blank window not flicker, and immediately became visible on the start page?
Quote from leopold on September 27, 2022, 8:29 amColleagues, I'm new to this topic, maybe I missed it, don't mind me.
When I start any compiled project the first thing I see on the screen is blank white window, and then after about half a second I see the start page design.
I tried compiling different sample projects - the same.
I tried compiling in NeoBook and ViseolNeoWin - the same.
Tried compiling in different modes, same result.How can I make white blank window not flicker, and start page become visible at once?

This is strange program behavior. Try to run your project with administrator rights, exclude VisualNEO Win from antivirus (if you use it). If it doesn't help, run your project on another computer to see if this behavior repeats there.

I followed all your advice - no result.
Tried on other computers, everything is ok on XP, ok on Win 7, on Win 10 LTSC - the same problem with any options.
Something in the Windows shell, it seems

Do you use any plugins in your project?
Try to disable them one by one to figure out which one affects you.
Can you make a project with only this problem and nothing else? So that we can replicate it in our place.

Well here is one of my sample projects.
One plugin is used there.

Yes, indeed, for about 0.1 second I have the program window empty and white at first and only then the window contents are rendered. I checked on a completely empty new project, adding only a page fill color in the page properties. The behavior is the same on NeoBook 5.8.7 and VisualNEO Win.
I guess I just didn't pay attention to it )).
No guarantees, but maybe Hans-Peter (@hpw) can fix it in the future.
For now, if it's annoying when loading the program, you can compile the project in tray-application form. But there will still be this effect when called from the tray. To mask the flicker, you can use a different type of fill, such as a photo with white around the edges, and then the change in background (from white window to photo) will not be noticeable.

Quote from Darbdenral on October 2, 2022, 9:02 am@leopold.. Yes, I can confirm too! I'm seeing the same behavior on a screen saver I just created. My background is black, but at start-up a blank white screen displays first for a split second..

Quote from HPW on October 2, 2022, 10:25 pmHello,
As Leopold told it seems OK on XP an Win7.
So MS break it on Win10.
One thing you may try is to use a Splash screen, which is shown before the start screen.

You can stop the blank white window flashing up in your Project if you really need to, by creating it with a Custom Shaped Window, rather than a Standard Window.
See Samples like Cool Calculator, which do not show this white window effect. (May also point the developers in the right direction to fix when run in a Standard Window.)

Yes, indeed, the method suggested by @paultomo works. I made a masked window and found no flicker.

The flicker depends on a few variables, such as the speed of the PC and how actions are stacked in your code. I agree with @rcohen ... Try to keep objects off-screen until they are needed. You can keep them to the left of your work area and slide them in when they need to be visible. If something flickers, cover it with a rectangle for example until the flicker stops and then remove the rectangle. There are a few ways to hide and animate objects, but the secret is how to make the user's experience visually pleasing. The legacy IE WebBrowser object is always white. There is no way to change the background color. It will be white until the page loads. So, cover it with a rectangle of the background color you want until the page loads. Then remove the rectangle. But remember that page loading time also depends a lot on the end user's PC.

I am almost certain the flicker is caused by the old Internet Explorer's WebBrowserObject when loading, and that there will be no flicker if you use the neoEdge.exe WebView2Loader instead.

No, the program window looks white for a small fraction of a second even if no object is in use, including the browser.
You can try flooding the start page with color and running the compilation. You will see a white window for a moment and only then a color.
(This is true for VisualNEO Win projects)
It happens so fast, I never paid attention to it :)).

Quote from leopold on December 1, 2022, 6:51 pmAn original way of solving this bug was found.
In the properties of the project set the initial position of the application window "outside left".
Create timer1, say 1 second,
and set commands for this timer :SetVar "[WindowLeft]" "[ScreenWidth]/2-[PubWidth]/2"
SetVar "[WindowTop]" "[ScreenHeight]/2-[PubHeight]/2"
TimerStop "Timer1"These commands will set the application window to the center of the screen.
