The following code example demonstrates how to display a MessageBox with the options supported by this overload of Show. After verifying that a string variable, ServerName
, is empty, the example displays a MessageBox, offering the user the option to cancel the operation. If the Show method's return value evaluates to Yes, the form that displayed the MessageBox is closed.
private:
void validateUserEntry5()
{
// Checks the value of the text.
if ( serverName->Text->Length == 0 )
{
// Initializes the variables to pass to the MessageBox::Show method.
String^ message = "You did not enter a server name. Cancel this operation?";
String^ caption = "No Server Name Specified";
MessageBoxButtons buttons = MessageBoxButtons::YesNo;
System::Windows::Forms::DialogResult result;
// Displays the MessageBox.
result = MessageBox::Show( this, message, caption, buttons );
if ( result == ::DialogResult::Yes )
{
// Closes the parent form.
this->Close();
}
}
}
private void validateUserEntry5()
{
// Checks the value of the text.
if(serverName.Text.Length == 0)
{
// Initializes the variables to pass to the MessageBox.Show method.
string message = "You did not enter a server name. Cancel this operation?";
string caption = "No Server Name Specified";
MessageBoxButtons buttons = MessageBoxButtons.YesNo;
DialogResult result;
// Displays the MessageBox.
result = MessageBox.Show(this, message, caption, buttons);
if(result == DialogResult.Yes)
{
// Closes the parent form.
this.Close();
}
}
}
Private Sub ValidateUserEntry5()
' Checks the value of the text.
If ServerName.Text.Length = 0 Then
' Initializes variables to pass to the MessageBox.Show method.
Dim Message As String = "You did not enter a server name. Cancel this operation?"
Dim Caption As String = "No Server Name Specified"
Dim Buttons As Integer = MessageBoxButtons.YesNo
Dim Result As DialogResult
'Displays a MessageBox using the Question icon and specifying the No button as the default.
Result = MessageBox.Show(Me, Message, Caption, MessageBoxButtons.YesNo)
' Gets the result of the MessageBox display.
If Result = System.Windows.Forms.DialogResult.Yes Then
' Closes the parent form.
Me.Close()
End If
End If
End Sub
The Button.DialogResult property and the Form.ShowDialog method use this enumeration.
