how to call other exe file in Eprime?

[chen]

Hi, I used to write Visual Basic scripts and now I want to use Eprime. But i don't know how to call executive function in Eprime.
 
Here is want I wrote in VB
(1) declare function
Public Declare Function ShellExecute Lib "shell32.dll" Alias _
"ShellExecuteA" _
(ByVal hWnd As Long, ByVal lpOperation As String, _
ByVal lpFile As String, _
ByVal lpParameters As String, _
ByVal lpDirectory As String, _
ByVal nShowCmd As Long) As Long
(2) call executive file
ShellExecute(NULL,"open","calc.exe",NULL,NULL,SW_SHOWNORMAL);
 
Now I want to call an executive file in Eprime, How to do that?
 
Besides, I have a USB device which can not only send a response signal but also generate a special number. It can be used as serial port device in VB, i can not only get the response but also get the number, How can i use it in Eprime? How can I control a serial port in Eprime?
 
Thank you very much!
