Tip: Sapgui.ScriptingCtrl.1 Replacement – Complete Launch Sequence of SAP GUI Scripting in VBScript

Often is here seen in the posts that the instantiation of the Sapgui.ScriptingCtrl.1 with the method OpenConnection is the reason of problems. Here is another way which bypass this problems by launching the SAP Logon. Also is it possible to terminate the SAP Logon.

    Dim SysDescr, SysIP
    SysDescr = "NSP" : SysIP = "192.168.203.134"

      Set Processes = WMIServ.ExecQuery("Select * from Win32_Process " & _

The function FindProcess is searching via the Windows Management Instrumentation (WMI) for the saplogon.exe process. If the process exists, we get the object SAPGUI from the Running Object Table (ROT). Otherwise we start a new instance of saplogon.exe and get the object SAPGUI. At the end we kill the process saplogon.exe via the sub procedure TerminateProcess.
