Hiding the Main Form

You can prevent the main form from appearing when your application starts by using the global Application variable.

To hide the main form at startup:

Choose ProjectView Source to display the main project file.
Add the following code after the call to Application.CreateForm and before the call to Application.Run.

Application.ShowMainForm := False;
Form1.Visible := False; { the name of your main form may differ }

Application->ShowMainForm = false;

Note: You can set the form's Visible property to False using the Object Inspector

at design time rather than setting it at runtime as in the previous example.
