SYMPTOMS

It may be tempting to call the Execute method of Internet Transfer Control in Form_Load with the intention to send a request automatically. However, the StateChanged subroutine may not get called if the method is called when the form is being loaded.

RESOLUTION

To send a request automatically with the Execute method, you can call the method in Sub Main() and set Sub Main() as the startup object:
  1. Add a module to the Visual Basic project.
  2. Add Sub Main() to the module.
  3. Select Sub Main() as the Startup Object from the project Properties.
  4. Remove Sub Form_Load from the form.
  5. Call the Execute method in Sub Main() as follows:
    Sub Main()
   Load Form1
   'Form1.Show
   ...
   Form1.Inet1.Execute ...
End Sub
