DIM DIM ... ... RfcReceiveTxt ( ( ) ) You can use the RFC generator to generate Visual Basic programs. Downloading generated Visual Basic programs only makes sense on Windows platforms which support Visual Basic. The generated program starts the corresponding SAP function module without you having to include any Visual Basic code. ... ...
RFC Example in Visual Basic © SAP AG Declare Function RfcOpenExt Lib "librfc.dll" ... Declare Sub RfcClose Lib "librfc.dll" ...... hRfc = RfcOpenExt(destination, mode, host, sysnr, ...) ... hSpace = RfcAllocParamSpace(3, 0, 1) rc% = RfcAddExportString(hSpace, 0, "COMPANY", 7, 0, 4, MyCompany) rc% = RfcAddExportString(hSpace, 1, "CUSTOMER", 8, 0, 10, MyCustomer) rc% = RfcAddExportString(hSpace, 2, "YEAR", 4, 6, 4, MyYear) thSales = ItCreate("SALES", 20 , 0, 0) rc% = RfcAddTable(hSpace, 0, "SALES", 5, 0, 20, thSales) RfcRc = RfcCallExt(hRfc, hSpace, "GET_SALES_BY_MONTH") ... If RfcRc = 0 Then RfcRc = RfcReceiveExt(hRfc, hSpace, xException) End If If RfcRc = 0 Then MsgBox "Function Call Failed !" RfcClose(hRfc) End If The above example shows RFC calls in a Visual Basic program fragment. Many details have been omitted, including the access to the results of the function calls, but you the fragment does contain the code for the following tasks: Declaring RFC calls Logging on to the R/3 System Defining the parameters and calls Error handling
