Hi

I want to remove minimize and maximize button from a running program (for exampel Notepad.exe)

From what I can understand this should be doable with "setwindowlong" function in the winapi.

After I get a handle to the Notepad I use "getwindowlong" to read the style (GWL_STYLE = -16)... and that works fine.

But after I change the windowstyle (a style without WS_MINIMIZEBOX and WS_MAXIMIZEBOX ) and apply it with "setwindowlong" nothing happens =(

Maybe Notepad.exe ignores the WM_STYLECHANGE message but then again the transparenty app posted on this foum works ok with notepad.

I did my testing with VisualBasic 2008 Express since im not that good with autohotkey and the windows api =/

Anyone that knows anything about this and could help me get on track ?

Maybe it's impossible to apply a new window style to a program that is already running... maybe I need to send a WM_PAINT message to the window or something... well im pretty lost.

Any help is helpful Very Happy

Code:
^F2::WinSet, Style, -0x30000, A ; WS_MAXIMIZEBOX 0x10000 + WS_MINIMIZEBOX 0x20000
^F3::WinSet, Style, +0x30000, A ; WS_MAXIMIZEBOX 0x10000 + WS_MINIMIZEBOX 0x20000


Run the above code. Ctrl+F2 will remove the buttons and Ctrl+F3 would bring them back.

Edit:

On a related note, The following creates a ToolWindow alike window, but with a regular-sized Titlebar and show in Alt-Tab:

Code:
Gui 1:+Owner -0x30000
Gui, 1:Show, w640 h480
