Are you using the .NET Web Service Browser ? See these two sites:

Hope it helps,

    Hi!!!

These two links are the "only" help to get on the ni support, and I have read them.

This case is about when the method is failing, then what to do ??? Some error handling advice?


I am using Labview 8.2 and .NET

Hi!!



When I try to make a .NET web server browser, by generating a assembly I get the following error:

Generating Assembly...


Error 1172 :Error calling method System.Web.Services.Description.ServiceDescriptionImporter.Import of ObjectId handle:
0xD061128 for obj 0xA82101[System.Web.Services.Description.ServiceDescriptionImporter] in domain [LabVIEW Domain for Run]
and thread 5412, (System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
    Inner Exception: System.InvalidOperationException: Unable to import binding 'ATV_Automation_Binding' from namespace
'http://www.appeartv.com/automation/v1/wsdl'.
    Inner Exception: System.InvalidOperationException: Unable to import operation 'getModuleList'.
    Inner Exception: System.InvalidOperationException: The element 'http://www.appeartv.com/automation/v1:getModuleList' is missing.
) in Import Service Description.vi->Generate Assembly.vi->Web Service Browser.vi



There is probably something wrong with the methods calls, since LW is unable to get the methode list. I would appresiate any suggestion.

So I guess you are using that...


The link you provided (http://10.110.30.228/automation/v1.wsdl) doesn't seem valid. So it's hard to test what's wrong.


To be honest, I never got anything usefull done with the created .NET dll's.


I'll have to communicate with a WDSL server soon, but it has to work under Linux. So we'll send xml strings wrapped in a SOAP message, and send it with a HTTP POST method. See http://zone.ni.com/devzone/cda/epd/p/id/3153 for information about sending the string with LabVIEW. The strings we'll send will look much like these: http://ws.cdyne.com/ip2geo/ip2geo.asmx?op=GetVersionInfo .


Sorry, not much help on the .NET stuff.


Wiebe.

Hi!!

I did make a try with http post (see attachment) with the aim to send a soap xml in the http post.
I do get an error when trying to parse the soap message (see message below).
Do you have suggestions for improvement of this VI???

All advice will be appresiated.
