Question

Backdrop: There are two forms, the main application form and a form to edit various settings for the operations of main application.

What would be the proper way to show the frmSettings form and how to dispose it once clicked OK or Cancel in the actual frmSettings form?

Answer 1

Perhaps a Dialog would be better suited to your Settings ‘form.’ There are subtle differences between a dialog and a form that would make the dialog easier to handle. A return code indicating the button that was clicked makes dialogs useful.

Supposing that you used a dialog – a using statement could be used (off the top of my head):

 using (DialogSettings dlgSettings = new DialogSettings) {   if (dlgSettings.ShowDialog() == DialogResult.OK)   {

} }

If you insist on using a form then you would have to

• Instance the form
• show the form
• record whether ok or cancel was clicked to a form level variable (from within the forms ok/cancel button click code)
• hide the form
• save the recorded value from the form
• dispose of the form
• make use of the saved ok/cancel value
