Hello Experts,

I am developing a Windows Service application in .Net.

While installing the service should take some config values from users and update the user settings in app.config file.

I have a Windows FORM in my project and i could call the windows FORM in my installer class.

public override void Install(System.Collections.IDictionary stateSaver)
        {
            base.Install(stateSaver);
         
            frmUserSettings f = new frmUserSettings()
                     
            f.ShowDialog();
           
        }


-------------------------------

the above code works and the FORM shows up during installation.

now i need to get the values from the FORM and update the user settings information in the app.config file.

any help?

Thanks

I removed windows FORM and tried using  Deployment project - User Interface Text boxes.
This is the code i am using right now in my installer code:
--------------------------
public override void Install(System.Collections.IDictionary stateSaver)
{
base.Install(stateSaver);
string str = Context.Parameters["SENDEREMAILADDRESS"].ToString();
Settings1 UserSettings = new Settings1();
UserSettings.EmailSender = str;
UserSettings.Save();
}
------------------------------
when i run, i am getting object reference not set to an instance
any idea what i am missing?

Make some public properties on your form so that you can access its data after the user has made the appropriate entries. Then you can add the data to your app.config file.
///////////////////////////////
//  Form code
///////////////////////////////
public class frmUserSettings : System.Windows.Forms.Form
{
    public string UserName { get; set; }
 
    protected void Form_Closing(object sender, EventArgs e)
    {
        this.UserName = this.textBox1.Text;
    }
}
 
///////////////////////////////
//  Service code
///////////////////////////////
public override void Install(System.Collections.IDictionary stateSaver)
{
    base.Install(stateSaver);
 
    frmUserSettings f = new frmUserSettings();
    
    f.ShowDialog();
    // Access via: f.UserName;
}

Open in new window
