In a 4D v16 single-user interpreted application for Windows 10, this code in the Startup method to hide the Application window has been executing successfully with no problem:
SET WINDOW RECT(-10;-10;-10;-10) //Win32API: $WindowHandle_l:=gui_GetWindowFrom4DWinEx (Frontmost window) $Error_l:=gui_ShowWindowEx ($WindowHandle_l;SW_HIDE) I just installed the application on a new Windows 10 computer, and now the Application window shows up. How to fix?
