问题 I want my window to be on top of all other windows in my application only . If I set the TopMost property of a window, it becomes on top of all windows of all applications and I don't want that. 回答1: You need to set the owner property of the window. You can show a window via showdialog in order to block your main window, or you can show it normal and have it ontop of the owner without blocking the owner. here is a codeexample of the codebehind part - I left out all obvious stuff: namespace

I have a form that pops up on a user's screen and has TopMost=true , but it steals the focus. How can I get it to not steal focus when it first appears? Hans Passant Paste this code in your form: protected override bool ShowWithoutActivation { get { return true; } } This is what worked for me. It provides TopMost but without focus-stealing. protected override bool ShowWithoutActivation { get { return true; } } private const int WS_EX_TOPMOST = 0x00000008; protected override CreateParams CreateParams { get { CreateParams createParams = base.CreateParams; createParams.ExStyle |= WS_EX_TOPMOST;

问题 I have a WinForm app that has other child forms (not mdi). If the user presses "Esc" the topmost form should be closed even if it doesn't have the focus. I can use a keyboard hook to globally catch the Escape but I also need the handle of the form to be closed. I guess there is a way to do that using Win32 API, but is there a solution using managed code? 回答1: Here is one way to get the topmost form that uses Win32 (not very elegant, but it works): public const int GW_HWNDNEXT = 2; // The next

问题 how to set the z-index windowsformhost that they are not always at the top of the WPF element ? 回答1: According to MSDN (Layout Considerations for the WindowsFormsHost Element) A hosted Windows Forms control is drawn in a separate HWND, so it is always drawn on top of WPF elements.
