  1. Dharmesh, have you made any progress on LabVIEW SAP integration. Do you have a working example?
  2. There isn't any ActiveX references of SalesOrder object. There are a lot of different objects in SAP with different interfaces. The objects are developed by SAP developers using ABAP. I can look up the interface in SAP documentation, but I don't have a proper ActiveX reference to cast.
  3. Hello, this is cross post from NI forum... http://forums.ni.com/t5/LabVIEW/SAP-BAPI-ActiveX-Interface/td-p/1715732 I'm trying to integrate our test stations to SAP ERP. SAP stores data in busines objects in busines object repository. The objects are exposed over BAPI interface. There is a lot of different busines objects in the repository. SAP developers can also build new objects if they want. The objective is to read inspection characeristics from quality management module of SAP. I haven't done much ActiveX stuff, neither know much about SAP, so I started with a simple example that I found searching for BAPI examples. The example works fine in Excel. The example just reads some data from a sales order object. Sub BAPI1()Dim oBook As Workbook Dim oSheet As Worksheet Dim oBAPICtrl As Object Dim oBAPILogon As Object Dim oSalesOrder As Object Dim oItem As Object Dim iIndex As Integer Set oBook = Application.ActiveWorkbook Set oSheet = oBook.Worksheets(1) '--------------------------------- ' Initialize SAP ActiveX Control. '--------------------------------- Set oBAPICtrl = CreateObject("sap.bapi.1") '--------------------------------- ' Initialize SAP ActiveX Logon. '--------------------------------- Set oBAPILogon = CreateObject("sap.logoncontrol.1") '----------------------------------- ' Initialize the connection object. '----------------------------------- Set oBAPICtrl.Connection = oBAPILogon.newconnection '-------------------- ' Logon with prompt. '-------------------- oBAPICtrl.Connection.System = "Q02" oBAPICtrl.Connection.Client = 101 oBAPICtrl.Connection.Logon '--------------------------------- ' Retrieve a sales order. '--------------------------------- Set oSalesOrder = oBAPICtrl.GetSAPObject("SalesOrder","0010732181") '----------------------------------- ' Display Sales Order header data. '----------------------------------- oSheet.Cells(2, 1).Value = oSalesOrder.salesdocument oSheet.Cells(2, 2).Value = oSalesOrder.netvalue oSheet.Cells(2, 3).Value = oSalesOrder.orderingparty.customerno oSheet.Cells(2, 4).Value = oSalesOrder.documentdate oSheet.Cells(2, 5).Value = oSalesOrder.items.Count '----------------------------------- ' Logoff SAP and close the control. '----------------------------------- oBAPICtrl.Connection.logoff Set oBAPILogon = Nothing Set oBAPICtrl = Nothing End Sub [/CODE] I tried to implement that in LabVIEW. The logon and logout part works, I can also obtain SalesOrder object with GetSAPObject method. There is no error and probing the Object output from GetSAPObject methods gives an integer value - probably a reference to the SalesOrder object. Now I can't figure out how do I read the object properties. It's very simple in VBA. I also don't know how do I call object methods. I would appreciate any hints... Bye, Mirko
  4. Very nice. I've been looking for this functionality also. Thank you for sharing this. Great! Mirko
  5. Great! Thank you for the nice tool.
  6. Hi, I have a table control on the front panel. I want to let the user to change the table column headers. Is there a simple way to detect the change of a column header? Using Key Up or Mouse Down events don't intercept all possible changes like entering a new value and clicking outside of the control. I must have overlooked something. Thanks, Mirko
  7. QUOTE (Mike C @ Sep 26 2008, 10:11 PM) I haven't done anything special. IIS is not running on my machine. I tried this on WinXP SP3 using LV 8.6 and Database Connectivity Toolkit. It is strange that it only works when I specify Microsoft.SQLSERVER.MOBILE.OLEDB.3.0 as provider in the connection string and not with Microsoft.SQLSERVER.CE.OLEDB.3.5 as one would expect. Is there a way to check what providers do I have installed on my machine? I don't like the error messages since they don't tell us anything usefull to solve the problem. Here is the VI that works on my machine. It uses a simple table with two columns - a numeric and b nchar.
  8. QUOTE (Mike C @ Sep 26 2008, 03:29 PM) I am also using sql server compact. I tried that connection string also and it didn't work neither. I found the strings http://www.connectionstrings.com/?carrier=sqlserver2005ce' rel='nofollow' target="_blank">here. I didn't give any password when creating the database. I got that error message few times. As a matter of fact, this is the only error message that I got - even for syntax errors in sql statements. Not very informative.
  9. I tried the same thing yesterday. I was able to connect to the database using the following connection string that I found googling the internet: Provider=Microsoft.SQLSERVER.MOBILE.OLEDB.3.0;Data Source=path\database.sdf You can create the database with Microsoft SQL Server Management Studio Express. I just tried a few SQL statemens and it seemed to work. I don't have a project in mind. It was just an attempt from my curiosity.
  10. In case somebody else has been bitten with non Windows-1252 code page bug, there has been LabVIEW 8.6f1 patch released. There was a problem when entering some charactes into string controls, caption, string constatns and free labels. Typing some language specific characters (like č in slovene) resulted in garbage and even chrased LabVIEW sometimes. After installing the patch, the problem has gone.

  12. Hi! I haven't used cFP yet, but I have succesfully connected PCs to Siemens S7/S5 PLCs. I use two methotds. First involvs calling functions from Prodave MPI DLL. Prodave MPI is an API product from Siemens. That of course won't run on cFP. The second method uses MPI/Ethernet converters. I that case you need to send commands to MPI/Ethernet converter over TCP/IP. I think this should work on cFP also. I use the MPI/Ehternet converter from IBHsoftec (http://www.s5w.business.t-online.de/english/Selection_Hardware_S7.htm), for which I can send you the VIs I use. This is all MPI protocol, not ProfibusDP. Mirko
  13. Put the following line into labview.ini funkyerrClustWire=True It works in LV7.0, I don't know about LV8, since I don't use it (yet).

    Talking to a PLC

    Hi, I'm using product called Prodave MPI ($$). This is an API from Siemens. It is a DLL with functions to read/write flags, data blocks, timers, inputs and outputs. Thera are two versions - full and mini. With mini version, only data block can be read or written. I can send you the VIs, so you don't have to study the DLL interface. They are only wrappers around DLL calls.
