Application.Exit() Doesn't close.

[Abadi]

Hey,

I've got a problem when I try to close an application.

I've got several forms and when the application loads, it creates a form like:

form2 frm2 = new form2();

Inside form2 there is a db connection. When the connection is not valid, it returns a messagebox and after that Application.Exit();

But it doesnt exit. It continuous loading Form1. Does anyone know what I am doing wrong?

Thankyou very much,

Abadi

Instead of using Application.Exit() you could show form2 as dialog. In this case, form1 will close the application when form2 'fails':

form1.cs:

      private void form1_Load(object sender, EventArgs e) {
         form2 frm2 = new form2();
         if (frm2.ShowDialog() == DialogResult.OK) {
            //do stuff
         }
         else {
            Close();
         }
      }


form2.cs
     private void form2_Load(object sender, EventArgs e) {
          //try to setup DB connect
          bool succeed = StartDbConnection();

          if (succeed)
             DialogResult = DialogResult.OK;
          else
             DialogResult = DialogResult.Abort;

      }

Thank you very much,,

it worked with a similair method,, When I use the showdialog, it shows the dialog what not should be. This is what I've done:


Form2
public boolean go;
try
{
DBconnection;
go = true;
}
catch (Exception er)
{
MessageBox.Show(er.Message, "Error");
go = false;
}

Program.cs
if(frm2.go == true)
{
Application.Run(new frm1());
}
else
{
Application.Exit();
}

It looks like that is the Main method. Why call Application.Exit() then?

      [STAThread]
      static void Main() {
         Application.EnableVisualStyles();
         Application.SetCompatibleTextRenderingDefault(false);

         if(frm2.go == true) {
            Application.Run(new frm1());
         }
         else {
             //do nothing, application will not start
         } 
      }

First, you can replace " if(frm2.go == true)" by "if(frm2.go)", because go is a boolean

Second, please use code-tags when you post code. use [ code] your code here [/ code] (without the spaces)
