Automation Error when called from VB 6

Hi Friend,

I have an application in VB 6 with Crystal Reports 7. Once I deploy the application using Package & Deployment Wizard, I get the error 'Automation Error' when I call the report from VB. I have deployed the .rpt file and not the complied file. I get this error occationally and not always. I also use Selection Formula, and Replace Selection Formula, both in VB code and also in the Report. Other reports function normally but just this one report gives me problems.

Have you come across this problem or do you have any idea of solving this ?

Please let me know if you do.

Bye.You might be missing a required dll.|||omalley might be right...............but it can be about a thousand things in CR - the error traps are so generic...:-(

I've seen this type of error when referencing objects in VB that are nor correctly type, for example.
eg dim myObj as Object
dim myObj as CRAXDRT.Report (which is the correct way to expose a report object and its properties and avoid the iUnknown interface on the COM layer, as I recall.)

It can also occur when automation servers used by CR are not available for some reason. I use some of my own UFLs (user function libraries that I developed in VB), which end up being exposed as "Additional Functions" in the formula editor. Any dll's with prefix UFL MUST be in same location as crpeaut32.dll or they will operate unreliably, even though properly registered using regsvr32.

Check also that your installation doesn't have some distributables on a network drive.

Once you've done that, make sure that you have properly passed your login info to the report in your code, and that you have also passed it to any subreports. This is a trap that bites many CR users - your database security may require you to supply login info to each subreport. It will also vary from OS to OS - standard XP security is much fussier than ME, for example.

As you can isolate it to a particular report that fails, are you doing anything differently to other reports, ie passing a different type of parameter, or maybe a range of parameters instead of a single one, and so on? Or maybe a different user is experiencing the problem.

Failing that, check the event log on the PC and see what information it is returning regarding the automation failure, and post that here.

Dave|||Thank You, omalley and springsoft for your comments. The code I use is given below;

'*****

CR.ReportFileName = App.Path & "\RouteCard.Rpt"

CR.DiscardSavedData = True
CR.Reset
CR.DiscardSavedData = False
CR.WindowShowRefreshBtn = True
CR.WindowShowSearchBtn = True
CR.WindowShowPrintSetupBtn = True

If CmbWoNoFrom.ListCount = 0 Then
MsgBox "No Records", vbInformation
Exit Sub
End If
ab = False
st1 = "({TblSchedulinghdr.Cancelled} = 0 and {TblPartNoWorkOrderNo.Cancelled}=0) and {TblOrderAcceptanceDetail.Move}='MOVE' "



If Trim(CmbWoNoFrom) <> "" Then
st1 = st1 & " AND {TblSchedulinghdr.SequenceWONo} >= " & Val(CmbWoNoFrom)
End If
If Trim(CmbWoNoTo) <> "" Then
st1 = st1 & " and {TblSchedulinghdr.SequenceWONo} <= " & Val(CmbWoNoTo)
End If
If Trim(CmbFinancialYear) <> "" Then
st1 = st1 & " and {TblSchedulinghdr.FinancialYear} = '" & UCase(Trim(CmbFinancialYear)) & "'"

End If
CR.SelectionFormula = st1





CR.Action = 1

'****

I use a database on the network which connects through ODBC and there is no database passwords set. There are 6 sub reports on this report and only one user gets this error at times. This package is compiled on win 2000 and deployed on win98.

Please let me know if you have any clue.

Thanx.
Bye.|||John,
Only potential problem I can see here (and it may not actually be a problem because you have given us a code snippet, not the whole lot), is that you are using combo boxes, by the look of your variable naming notations (which bears some resemblance to Charles Simonyi's Hungarian C Notation, with an indicative type prefix on variable and object names).
If CmbWoNoFrom (for example) is actually a combo box, what are you doing to trap situations where user presses Print button without actually selecting an item from each combo?
Unless you have a default value already set, and it doesn't look like you have, as you are Val'ing the combo's selection, then a failure to select the value may cause the query to fail, because it is passing a value (probably -1) that the query can't handle.

Dave|||Thnak You springsoft for your observations.

I don't think an empty combo box would produce an error as the check for an empty trimmed combo is done before the expression is built. This particular machine had some virus problems and also has a keyboard device driver alert in device manager. Does this pose any potential problem, although I feel it should'nt.

Please let me know of your views.

Thanx.

Bye.

Automating Data Extension Deployment

Hi,

I have written a Data Processing extension for my application and can deploy it on my development machine no problems. My question is: what is the "correct" way of deploying an extension to an end user's machine? Do I have to write a special program to find and modify the Reporting Server config files and copy the extension over. Surely many developers have the same need so there must be a generic solution to this problem, however, I haven't managed to find one.

I first came across this issue in SQL2000 and I thought/hoped it would be rectified with SQL2005 but it appears not to be (unless I'm missing something).

Any ideas would be greatly appreciated.

Thanks in advance,

Tim

Hi Tim,

I don't have an answer for you, but I share your situation. I'll let you know if I find anything, and would appreciate the same.

TIA, Mike.

Automatic deployment of report models

Hi all,
I have a group of models, and I'm looking for a way to automatically
get them to deploy to the test report server every day. The only way I
know to deploy is to build the models in Visual Studio and then deploy
them from Visual Studio. Are there other ways (command line solutions
perhaps) that will do this?
Thanks for any answers.
MattYou should be able to do this via the RS Web Service Interface.
Someone should write a utility that monitors a folder or folders and auto
deploy reports from there, that would be really useful

Saves me tons of time, especially with client deployments. :)

Thanks very much for the replies. I started looking at the
ReportingServices2005 web services, and found a method called
"CreateModel" that looks like it might help, but I can't figure out how
to structure a call to this method, and how to authenticate etc...
There is a lack of examples on the web with this information. Its
slightly more complicated for me too because we also develop a custom
authentication extension that we'll have to cater for in the web
services calls.
Chris, any chance you could share your application or at least some
code that describes how its done.
Thanks!

I'm looking for a relatively simple example implementation of some code
using the web services to publish a report model.

Automate deployment of reporting project

I have to deploy reports several times a day [to our teesting environment]
due to contstant changes by devlopers. Does anyone know of a way to automate
the deployment process? Even doing something with VBA will work. I don't
see any possible references listed in the VBA references section - would the
createobject method work? Has anyone does this? I would love to get this on
a schedule and off my plate.
Thanks in advance,
John Hennesey
p.s. Third party programs are an option too, if anyone knows of any.You should be able to do all you need with a bit of scripting and the rs
utility. The following link should give you an idea, based on the reporting
services sample reports:

massaging to get it to where I want it to be. Ideally if I could use the
Visual Sourcesafe object model to pull down the latest code, then use a .Net
object model to open the solution, change the deployment path then deploy it
would be ideal.
But, I can use command line script to pull down the latest code base from
SS, then iterate through the file list (.rdl's only) via the Scripting engine
and deploy from there.
Thanks for your help!
