Is there a way how to dimm or make the (x) windows button of a panel invisible?

[Ramles97]

Hi everyone,

I would like to know if there is a function, which I can use to dimm or make the (x) Windows button of the panel invisible, since I already added a button in the panel that closes the program.

Thanks a lot in advance.

You can try with  SetPanelAttribute (panelHandle, ATTR_SYSTEM_MENU_VISIBLE, 0);
