Hi everyone! I have a quick question regarding the ShowDialog method. I have a second form that I want to be shown upon a button click. I have this method so far:

C#

private void insertMakeButton_Click(object sender, EventArgs e)
        {
            newMakeForm.ActiveForm.ShowDialog();
        }

The error I'm getting when I click on the corresponding button is:
Form that is already visible cannot be displayed as a modal dialog box. Set the form's visible property to false before calling showDialog.

Can someone shed some light as to what I'm doing wrong?

Thanks everyone!

Perfectly formal answer which makes no practical sense at all. After some thinking, I decided to vote 5... :-)

The insertButton is on the original form and the newMakeForm is the 2nd form. I want the text on newMakeForm to be added to the comboBox on the original form.
