Application.Exit() Doesn't close.
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

Re: Application.Exit() Doesn't close.
Instead of using Application.Exit() you could show form2 as dialog. In this case, form1 will close the application when form2 'fails':
Code:
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;
}

Re: Application.Exit() Doesn't close.
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();
}

Re: Application.Exit() Doesn't close.
It looks like that is the Main method. Why call Application.Exit() then?
Code:
[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)
