How to get the custom WPF dialog box in visual studio

Vasu Bansal 20

I am using webview2 to display the page on the wpf dialog box initially the issue is there was visual studio icon that was coming by default on the top left I want to remove that icon so that I used WindowStyle="ToolWindow" due to this my minimize and maximize icons are gone also my close button is modified which is not looking good, So is there any good way just to remove the visual studio icon that is coming currently i am using this piece of code

<Window x:Class="xyz"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:local="xyz"

xmlns:wv2="clr-namespace:Microsoft.Web.WebView2.Wpf;assembly=Microsoft.Web.WebView2.Wpf"

mc:Ignorable="d"

WindowStyle="ToolWindow"

WindowStartupLocation="CenterScreen"

Title="Title"

Width="620"

Height="400">

<DockPanel>

<wv2:WebView2 Name = "webView" />

</DockPanel>

</Window>

This is the title bar initially with the visual studio icon

User's image

This is when we use WindowStyle="ToolWindow" User's image

Hi @vasu bansal , Welcome to Microsoft Q&A,

WPF does not provide a general way to directly remove the icon.

But you can override it through code customization.

protected override void OnSourceInitialized(EventArgs e)
{
    IconHelper.RemoveIcon(this);
}
public static class IconHelper
{
    [DllImport("user32.dll")]
    static extern int GetWindowLong(IntPtr hwnd, int index);

    [DllImport("user32.dll")]
    static extern int SetWindowLong(IntPtr hwnd, int index, int newStyle);

    [DllImport("user32.dll")]
    static extern bool SetWindowPos(IntPtr hwnd, IntPtr hwndInsertAfter,
               int x, int y, int width, int height, uint flags);

    [DllImport("user32.dll")]
    static extern IntPtr SendMessage(IntPtr hwnd, uint msg,
               IntPtr wParam, IntPtr lParam);

    const int GWL_EXSTYLE = -20;
    const int WS_EX_DLGMODALFRAME = 0x0001;
    const int SWP_NOSIZE = 0x0001;
    const int SWP_NOMOVE = 0x0002;
    const int SWP_NOZORDER = 0x0004;
    const int SWP_FRAMECHANGED = 0x0020;
    const uint WM_SETICON = 0x0080;

    public static void RemoveIcon(Window window)
    {
        IntPtr hwnd = new WindowInteropHelper(window).Handle;
        int extendedStyle = GetWindowLong(hwnd, GWL_EXSTYLE);
        SetWindowLong(hwnd, GWL_EXSTYLE, extendedStyle | WS_EX_DLGMODALFRAME);
        SetWindowPos(hwnd, IntPtr.Zero, 0, 0, 0, 0, SWP_NOMOVE |
              SWP_NOSIZE | SWP_NOZORDER | SWP_FRAMECHANGED);
    }
}
