message loop (Application.Run) only after validating login?

If I use Application.Run(new LogonForm()) and try returning a boolean parameter to indicate successful/unsuccessful logon, the project doesn't build successfully.

int main()
{
     bool loginValidated = false;
     using (LoginWindow window = new LoginWindow())
     {
         loginValidated = window.ShowDialog() == DialogResult.OK;
     }

     if(loginValidated)
     {
         // starts the application message loop
         Application.Run(new ProcessForm());
         /* .... */

IMO, you need to use Application.Run only when the login is successful. As I said, before calling Application.Run, validate the login and if successful call it. To get the validation result back, you can use DialogResult enum provided with .NET framework. You can do like this,int main(){ bool loginValidated = false; using (LoginWindow window = new LoginWindow()) { loginValidated = window.ShowDialog() == DialogResult.OK; } if(loginValidated) { // starts the application message loop Application.Run(new ProcessForm()); /* .... */ }}Inside the login form, once you validate all the details, write like

this.DialogResult = DialogResult.OK;

FileStream oFileStream = new FileStream("FilePath", FileMode.OpenOrCreate);
oFileStream.Write(YourByteArray,0,YourByteArraySize);

Use Process.Start method once the save is complete. It will open the file in the associated program

public int SomeProperty
{
    get
    {
         return this.someField;
    }

    set
    {
        if (this.someField != value)
        {
            this.someField = value;
            // do all sorts of stuff here that only happens if someField has actually changed
            this.Invalidate();
        }
    }
}
