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: void button1_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ ) { ColorDialog^ MyDialog = gcnew 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() == ::System::Windows::Forms::DialogResult::OK ) { textBox1->ForeColor = MyDialog->Color; } }
