Looping problem in DTS with ActiveX
(a) a holding table is truncated and 1 blank record is inserted into the holding table,
(b) the XML data in the file is inserted into the holding table via TextCopy.exe,
(c) the XML data is parsed using OPENXML and inserted into 2 additional holding tables, and
(d) the XML file is archived to another directory.
After (a), (b), (c), and (d) are completed, the DTS package loops back and executes (a), (b), (c), and (d) for the other remaining files.
It all worked flawlessly in testing, until I commented out a MsgBox line in the ActiveX task for item (b) above. Without the MsgBox command, the other tasks (b) and (c) don't appear to execute, though I can see that the looping is working, since the source files get moved to the archive location (in step (d)).
Attached is a screenshot of the DTS package (it can also be viewed at http://www.nmwildlife.org/images/DTS_screenshot.gif).
I think that the MsgBox issue is a red herring; in other words, I'm thinking that when I click the OK button on the MsgBox, there might be something about the return code which allows the tasks to be executed properly. However, I'm not a VBScript expert, so can't figure out where the problem lies or how to fix it.
Here's the code for the "Import w/ShellCmd" ActiveX task:
Function Main()
Dim objShell
Dim strPath
Dim strCmd
strPath = CSTR(DTSGlobalVariables("gv_FileFullName").Value)
strCmd = """C:\Program Files\Microsoft SQL Server\MSSQL\Binn\TextCopy.exe"" /S ""GROVER"" /U sa /P """" /D TESTProlaw /T dc_XML /C myXML /F " & _
strPath & _
" /W ""WHERE 1=1"" /I /Z"
Set objShell = CreateObject("WScript.Shell")
objShell.Run strCmd
Set objShell = nothing
MsgBox ""
Main = DTSTaskExecResult_Success
End Function
And here's the code for the "Begin Loop" ActiveX task:
Option Explicit
Function Main()
dim pkg
dim stpEnterLoop
dim stpFinished
set pkg = DTSGlobalVariables.Parent
set stpEnterLoop = pkg.Steps("DTSStep_DTSExecuteSQLTask_2") 'Start loop at the "Truncate dc_XML" task
set stpFinished = pkg.Steps("DTSStep_DTSActiveScriptTask_5")
' We want to continue with the loop only of there are more than 1 text file in the directory.
' If the function ShouldILoop returns true then we disable the step that takes us out of the package and continue processing
if ShouldILoop = True then
stpEnterLoop.DisableStep = False
stpFinished.DisableStep = True
stpEnterLoop.ExecutionStatus = DTSStepExecStat_Waiting
else
stpEnterLoop.DisableStep =True
stpFinished.DisableStep = False
stpFinished.ExecutionStatus = DTSStepExecStat_Waiting
End if
Main = DTSTaskExecResult_Success
End Function
Function ShouldILoop
dim fso
dim fil
dim fold
dim pkg
dim counter
set pkg = DTSGlobalVariables.Parent
set fso = CREATEOBJECT("Scripting.FileSystemObject")
set fold = fso.GetFolder(DTSGlobalVariables("gv_FileLocation").Value)
counter = fold.files.count
'So long as there is more than 1 file carry on
if counter >= 1 then
for each fil in fold.Files
DTSGlobalVariables("gv_FileFullName").Value = fil.path
ShouldILoop = CBool(True)
Next
else
ShouldILoop = CBool(False)
End if
End Function
The goal is to get the DTS package to run without having to manually click OK on the MsgBox; that way, I can schedule it to run automatically.
Any help would be greatly appreciated. Thanks in advance!no, here the MsgBox is not returning anything. it should run perfectly without the MsgBox. i think it was used to give the shell the time to complete the process.
what u can try is - executing the shell in sync mode and drop the MsgBox. use this code and see if it works
....
Ret = objShell.Run (strCmd,,true)
.....sql

Looking for ideas
Hi everyone
We've got currenlty around 500 dts 2000 in production.
In order to know in what ETL processes we have Oracle connections, or FTP tasks or whatever, we did a VB6 app using dtspkg.dll which load all the properties for each DTS into Sql server tables. So that, then you could see from a specific DTS how many connections, Sql Tasks it had and so on..
How to accomplish the same with SSIS? I know, doing the same but using .Net, of course, but is there any else approximation? I am little bit concerned when we will have hundreds of them up.
Maybe 2005 is offering this feature automatically, I don't know.
Thanks in advance for your time/advices/ideas,
Try this -
Download details: SQL Server 2005 Business Intelligence Metadata Samples Toolkit

Even if the tools are visualisation is not what you want, it will have populated some tables with details of packages and objects that you can probably use. And if that is still not good enough the source code included will give you a start in writing your own tool.
