Delete standard icon in windows form

开发者_StackOverflow社区how to just delete that windows form application icon in the left corner without replacing it with another icon?

I assume that you're using .Net WinForms.

Set the form's ShowIcon property to false.

If it is .NET (Winforms) the form should have a ShowIcon property. Set this to false.

in case you're using C++

HWND hWnd;  // = WindowHandle()
::SetWindowLong(hWnd, GWL_EXSTYLE, 
                ::GetWindowLong(hWnd, GWL_EXSTYLE) | WS_EX_DLGMODALFRAME);
