Showing a TextBox icon in the Visual Studio Toolbox

Hi,

I'm creating a custom textbox control (CustomTextBox).
I use a ToolBoxBitmapAttribute to show an icon in the Visual Studio Toolbox:

C#

[ToolboxBitmap(typeof(TextBox))]
    public sealed class CustomTextBox : TextBox

I try to show the same icon for my text box as the icon for the System.Windows.Forms.TextBox.
Now, I'm expecting a TextBox icon in the toolbox for my CustomTextBox, but I see this icon:
www.codeproject.com/script/Membership/Uploads/8966127/ControlIcon.png[^]
So, I tried also this code:

C#

[ToolboxBitmap(typeof(TextBox),"System.Windows.Forms.TextBox.bmp")] // System.Windows.Forms.TextBox.bmp is the resource name of the icon for the TextBox, according to my decompiler
    public sealed class CustomTextBox : TextBox

But I still see this icon:
www.codeproject.com/script/Membership/Uploads/8966127/ControlIcon.png[^]
How can I show the TextBox for my CustomTextBox in my tool box instead of the other icon?

Note: my CustomTextBox class is in another assembly than my Windows Forms project, and I add a reference to the assembly with my CustomControl.

Thanks in advance.

Try following code, it works for me:

C#

[ToolboxBitmap(typeof(TextBox), "TextBox.bmp")]
    public sealed class CustomTextBox : TextBox
    {

    }

And don't forget to remove and add again your component to toolbox after recompile.

Now, it's working also without "TextBox.bmp". The reloading of the component was the trick.
