Question

I am very weak in overriding, overloading etc. so I couldn’t handle this. My problem is this,

I have a frmDialog. It is only used to show the process messages, error messages etc. It takes its text from log, so I don’t need to pass a variable to it. After each process(on other forms), I create this form and call ofrmDialog.ShowDialog(). My problem is that, even when the text is empty, this dialog box opens and shows nothing. So I wanted to override this ShowDialog. ShowDialog returns DialogResult, so I really can’t figure out how to do this.

public override DialogResult ShowDialog(){
    if(this.Text != string.Empty){
    return base.ShowDialog();
    }
    else{
    //don't do anything
    }
}

What do I return when there is else? I really can’t understand this.

Personally I’d recommend putting the ShowDialog in an if statement so that it’s only triggered if the text isn’t empty.

e.g.

if(text is not empty)
{
    //Show dialog
}

That way you can avoid the issues you’re currently having. If you have to return something you can set DialogResult to equal what it needs to be – OK or Cancel for example.

Based on your comments however, I suggest you put this in the else statement of your code:

else
{
    return base.ShowDialog = "<OK>";
}
