Başka bir uygulamanın windows stilini winAPI

Question

kullanarak değiştirin Uygulamam başka bir uygulama başlatır. Bu sayede, C# kullanarak başlatılan uygulamanın başlık çubuğunu kaldırmak istiyorum.

Bunu aşağıdaki kod parçasından başlayarak nasıl yapabilirim?

//Get current style 
lCurStyle = GetWindowLong(hwnd, GWL_STYLE) 

//remove titlebar elements 
lCurStyle = lCurStyle And Not WS_CAPTION 
lCurStyle = lCurStyle And Not WS_SYSMENU 
lCurStyle = lCurStyle And Not WS_THICKFRAME 
lCurStyle = lCurStyle And Not WS_MINIMIZE 
lCurStyle = lCurStyle And Not WS_MAXIMIZEBOX 

//apply new style 
SetWindowLong hwnd, GWL_STYLE, lCurStyle 

//reapply a 3d border 
lCurStyle = GetWindowLong(hwnd, GWL_EXSTYLE) 

SetWindowLong hwnd, GWL_EXSTYLE, lCurStyle Or WS_EX_DLGMODALFRAME 

//redraw 
SetWindowPos hwnd, 0, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE Or SWP_FRAMECHANGED
