CommonDialog Class
Specifies the base class used for displaying dialog boxes on the screen.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Inherited classes are required to implement RunDialog by invoking ShowDialog to create a specific common dialog box. Inherited classes can optionally override HookProc to implement specific dialog box hook functionality.
Windows Mobile for Pocket PC, Windows Mobile for Smartphone, Windows CE Platform Note: This class is not currently supported on the .NET Compact Framework, but will be supported in a future release.
The following code example uses the ColorDialog implementation of CommonDialog and illustrates creating and showing a dialog box. This example requires that the method is called from within an existing form, which has a TextBox and Button placed on it.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim MyDialog As New ColorDialog() ' Keeps the user from selecting a custom color. MyDialog.AllowFullOpen = False ' Allows the user to get help. (The default is false.) MyDialog.ShowHelp = True ' Sets the initial color select to the current text color, MyDialog.Color = TextBox1.ForeColor ' Update the text box color if the user clicks OK If (MyDialog.ShowDialog() = Windows.Forms.DialogResult.OK) Then TextBox1.ForeColor = MyDialog.Color End If End Sub
