This part is a two step process…
Declare the method using Extern.Declare
Example
Extern.Declare
micHwnd, “FindWindow”, “user32.dll”, “FindSomeWindow”,
micString, micString
Here:
micHwnd -the data type of value returned by method
FindWindow -the user supplied procedure name. You can set
it to anything as long as it’s a valid syntax.
user32.dll -the DLL from where you wish to call the method
FindWindowA -The actual method name inside the DLL
Last two are the data types of the arguments that will be
passed to the procedure
