WPF如何禁用最小化按钮
使用默认的样式设置，只能设置禁用最大化，无法设置禁用最小化。最终还是发现，需要用到api函数。只是不知道在win7下面工作情况如何。

I've stolen some code I found on the MSDN forums and made an extension method on the Window class, like this:
internal static class WindowExtensions { [DllImport("user32.dll")] internal extern static int SetWindowLong(IntPtr hwnd, int index, int value); [DllImport("user32.dll")] internal extern static int GetWindowLong(IntPtr hwnd, int index); internal static void HideMinimizeAndMaximizeButtons(this Window window) { const int GWL_STYLE = -16; IntPtr hwnd = new System.Windows.Interop.WindowInteropHelper(window).Handle; long value = GetWindowLong(hwnd, GWL_STYLE); SetWindowLong(hwnd, GWL_STYLE, (int)(value & -131073 & -65537)); } } The only other thing to remember is that for some reason this doesn't work from a window's constructor. I got around that by chucking this into the constructor:
this.SourceInitialized += (x, y) => { this.HideMinimizeAndMaximizeButtons(); }; Hope this helps!
移除关闭按钮
// Disable close button
private const int MF_BYPOSITION = 0x400
;
[
DllImport("User32"
)]
private static extern int RemoveMenu(IntPtr hMenu, int nPosition, int wFlags
);
[
DllImport("User32"
)]
private static extern IntPtr GetSystemMenu(IntPtr hWnd, bool bRevert
);
[
DllImport("User32"
)]
private static extern int GetMenuItemCount(IntPtr hWnd
);
internal static void RemoveCloseButton(Window window
)
{
IntPtr hMenu = GetSystemMenu(new WindowInteropHelper(window).Handle, false
);
int menuItemCount = GetMenuItemCount(hMenu
);
RemoveMenu(hMenu, menuItemCount - 1, MF_BYPOSITION
);
禁用最小化或最大化按钮
// Disable minimize and maximize buttons
[
DllImport ( "user32.dll"
)]
internal extern static int SetWindowLong ( IntPtr hwnd , int index , int value
);
[
DllImport ( "user32.dll"
)]
internal extern static int GetWindowLong ( IntPtr hwnd , int index
);
internal static void DisableMinimizeButton ( this Window window
)
{
const int GWL_STYLE = - 16
;
IntPtr hwnd = new System . Windows . Interop . WindowInteropHelper ( window ). Handle
;
long value = GetWindowLong ( hwnd , GWL_STYLE
);
SetWindowLong ( hwnd , GWL_STYLE , ( int )( value & - 131073
));
}
internal static void DisableMaximizeButton ( this Window window
)
{
const int GWL_STYLE = - 16
;
IntPtr hwnd = new System . Windows . Interop . WindowInteropHelper ( window ). Handle
;
long value = GetWindowLong ( hwnd , GWL_STYLE
);
SetWindowLong ( hwnd , GWL_STYLE , ( int )( value & - 65537
));
internal static void DisableMinimizeAndMaximizeButtons(this Window window)
{
const int GWL_STYLE = -16;
IntPtr hwnd = new System.Windows.Interop.WindowInteropHelper(window).Handle;
long value = GetWindowLong(hwnd, GWL_STYLE);
SetWindowLong(hwnd, GWL_STYLE, (int)(value & -65537 & -131073));
}
