Icon Conundrum

The main window of my utility app should not have an icon in the Title bar. If you do not specify your own icon for the compiler to use, a system default icon is used in the Title bar. The default icon can be suppressed using an extended window style:

Code:

SetWindowLongPtr_(WindowID(#Win), #GWL_EXSTYLE, GetWindowLongPtr_(WindowID(#Win), #GWL_EXSTYLE) | #WS_EX_DLGMODALFRAME)

That certainly works with the system default icon, but if an icon is specified in the compiler, it still appears on the Title bar, meaning that your own icon cannot be applied to the exe file if you want it omitted from the window title bar............

Anybody have a workaround without resorting to a 'Tool' window?

That's why I don't specify an icon in the compiler. :wink:

I keep images in a datasection and set an explicit icon for each window.

That's an interesting idea. I assume it still works if an icon is specified for the compiler to use as the exe icon.

......It isn't a solution to my issue though, because I want an icon for the exe, but not for the window.

Edit: Unless there is a 'set icon' type of message (like PB's SetWindowTitle) which would permit the setting of 'no icon'

Simply set the icon to "none" before applying #WS_EX_DLGMODALFRAME, like this:

Code:

Procedure WindowRemoveIcon(WindowNr)
   Protected WindowID = WindowID(WindowNr)

   SetClassLongPtr_(WindowID, #GCL_HICON, 0)
   SetWindowLongPtr_(WindowID, #GWL_EXSTYLE, GetWindowLongPtr_(WindowID, #GWL_EXSTYLE) | #WS_EX_DLGMODALFRAME)
EndProcedure

Your original idea worked for me(Win7/XP) if you don't specify an icon in the exe.
Then overwrite the icon for additional windows as needed.

Code:

; Set/Change icon.
SendMessage_(WindowHandle), #WM_SETICON, 0, ImageHandle) ; 0=ICON_SMALL, 1=ICON_BIG

; Drop icon.
SetWindowLongPtr_(WindowHandle, #GWL_EXSTYLE, GetWindowLongPtr_(WindowHandle, #GWL_EXSTYLE) | #WS_EX_DLGMODALFRAME)

Sorry guys, you are missing the point. My icon is wanted for the exe, but not wanted for any window. Using #GWL_EXSTYLE will only remove the system icon, not the one (my icon) embedded by the PB compiler. Possibly hacking the exe to replace the icon might work, have not tried that.
