standard dialog buttons

Hi does anyone know how to disable the standard minimise maximise and close buttons on the installation dialog box. I have been looking through the modern user interface but cant find anything on this. many thanks

Watch out for the close button as NSIS handles it according to the cancel button as of version 2.26.

!define SC_MINIMIZE 0xF020

!define SC_MAXIMIZE 0xF030

!define SC_CLOSE 0xF060



!define MF_GRAYED 1



System::Call 'user32::GetSystemMenu(i $HWNDPARENT, i 0) i .r0'

System::Call 'user32::EnableMenuItem(i s, i ${SC_MINIMIZE}, i ${MF_GRAYED})'

System::Call 'user32::GetSystemMenu(i $HWNDPARENT, i 0) i .r0'

System::Call 'user32::EnableMenuItem(i s, i ${SC_MAXIMIZE}, i ${MF_GRAYED})'

System::Call 'user32::GetSystemMenu(i $HWNDPARENT, i 0) i .r0'

System::Call 'user32::EnableMenuItem(i s, i ${SC_CLOSE}, i ${MF_GRAYED})'
