C# MessageBox with DialogResult giving "No overload for method 'Show' takes '3' arguments"

Question

I am developing an application for Windows CE using Visual Studio 2008.

Code:

    private void cmdLogOn_Click(object sender, EventArgs e)
      {
        if (loginStatus == false)
        {
            DialogResult dialogresult = MessageBox.Show("Are you sure?", "text", MessageBoxButtons.YesNo);
            if (dialogresult == DialogResult.Yes)
            {
                //Do Stuff;
            }
        }
        else
        {
            //Do stuff
        }
    }

I am getting the error : "No overload for method 'Show' takes '3' arguments". Any idea why?

EDIT: Here is a step by step using a new application to demonstrate the issue:

1. As you can see, I am using VS2008

2.Visual C# > Smart Device Project

3. Target platform: Windows CE - .NET Compact Framework Version 3.5

4. I create a button = button1 & a label = label1

5. Here is the code I entered, but the error persists

Answer 1

The simple answer is in the .NET Compact framework there is no overload which takes 3 arguments, as the error says.

You can use this:

DialogResult dialogresult = MessageBox.Show("Are you sure?", "text",
    MessageBoxButtons.YesNo, MessageBoxIcon.None, MessageBoxDefaultButton.Button1);
