Problem in using OCX in VB6 - error information "Bad variant type"

[Former Member]

I'm running an interface developed in Visual Basic 6.0.

The source is:

Set LogonControl = CreateObject("SAP.LogonControl.1")

LogonControl.SystemNumber = Trim(data("SYSTEMNUM"))

LogonControl.Language = Trim(data("LANGUAGE")

LogonControl.Client = Trim(data("MANDANT")

LogonControl.ApplicationServer = Trim(data("APPSERVER"))

LogonControl.User = Trim(data("USER"))

LogonControl.Password = Trim(data("PASSWORD"))

Set SAPConn = LogonControl.NewConnection

SAPConn.Logon(0, True)

Set LsapFuncSAP = CreateObject("SAP.Functions")

Set LsapFuncSAP.Connection = SAPConn

Set LsapFuncRFC = LsapFuncionesSAP.Add "FUNCNAME"

LsapFuncRFC.Call

.......

I have SAP GUI 6.20 installed and the APP server is "R/3 Release 4.6C" with Oracle.

but in the line "Set LsapFuncSAP.Connection = SAPConn" generates one of this errors randomly:

"Bad variant type" or

"Internal application error"

When I make the connection to development SAP server, this interface works fine, but when I make the connection to the QA SAP server, doesn't work anymore.

I'm running this application from the same Windows 2000 Server allways...just change the SAP server I'm connecting to.

Thanks...
