Introduction

Verify if the windows or form is loaded.

Declaration Function FindWindow
Private Declare Function FindWindow Lib "USER32" Alias "FindWindowA" _
(ByVal lpszClassName As String, ByVal lpszWindow As String) As Long

Call the function:
If FindWindow(vbNullString, Caption) Then
   msgbox "Yes"
Else
   msgbox "No"
End If

You can verify if a window or form is open not only from visual basic, from windows itself For example you can verify if the application CALC.EXE is loaded.

Se puede verificar no solo los formularios abeirtos dentro de Visual Basic, sino tambien cualquier ventana que se encuentre abierta en Windows.
