*Premises
Winapi WS_SIZEBOX is specified. (ON)
Non-resizable window is specified. (OFF)
Permission of full screen switching is specified off. (Off)
Pattern ①.
Window can be resized during splash logo (a two-way arrow is displayed).
You can continue resizing once you enter the game (a two-way arrow is displayed)
Once you enter the game, you can resize the window as many times as you like (a two-way arrow will appear).
Toggle to enable full-screen mode to enter full-screen mode, and to disable it to return to full-screen mode.
After that, you will not be able to continue resizing the window during the game (the two-way arrow will not appear).
Pattern (2)
Window does not resize during splash logo (two-way arrow appears, but is not clicked)
The window cannot be resized once you enter the game (the two-way arrow does not appear)
Cannot resize as many times as I enter the game (no two-way arrow appears) Toggle to enable full-screen mode to enter full-screen mode and disable it to return to full-screen mode.
I am then still unable to continue resizing the window during the game (no two-way arrow appears)
I would like the bi-directional arrows to appear during the game as well as during the splash window with the “*premise” setting, but I can’t!
I use winapi! C#
Can you please help me?
