[Openroad-users] OR App Server from within C#

[Pete Rabjohns]

Thanks Neil,

 

I was already doing the ref Object thing already, and now that I think
about it, I'm beginning to wonder whether this is an XML serialisation
problem,

 

I have a class with several 'objects' as attributes, the whole class is
used as the input message for a Web Service.

 

Inspection of the object shows that it is an array of one entry and I am
passing this object into the SetAttribute method.

 

e.g.

 

public class Params

{

            Object Param1 ;

            Object param2;

            Object Param3;

}

 

Public class WebServices : WebService

{

            [WebMethod]

            Public results Method1 (params in) 

{

            ....

 

ParameterDataObj.DeclareAttribute ("param1","string");

ParameterDataObj.SetAttribute ("param1", in.param1);   <------ This line
fails with a type conversion error

}

 

            ...

 

}

Hi Pete, 

 

Maybe the problem is one of boxing params into objects?  See the UKIUA
site /conference/Autumn2005/NeilWarnock_1005.pdf  slide 16.

 

    ...

 

    try {

 

 /* declare params to pass */

 

        pdo.DeclareAttribute("hellostring", "STRING");
        pdo.DeclareAttribute("counter"    , "INTEGER");

 

 /* set params to pass - use object references */

 

        Object objStr = "Hello AppServer from C#!");
        pdo.SetAttribute("hellostring", ref objStr);

 

        Object objInt = 99;
        pdo.SetAttribute("counter", ref objInt);

 

 /* Make call - passing an object reference */

 

 Object objPDO = pdo;
        rso.CallProc("HelloWorld", null, ref objPDO);
        
    /* process values in the byref pdo */ 

 

        Console.WriteLine("hellostring = {0}",
pdo.GetAttribute("hellostring").ToString());
        Console.WriteLine("counter     = {0}",
pdo.GetAttribute("counter").ToString());

Hi,

 

Anyone get any examples of calling OR4.1 App Server objects from within
c#?

 

I'm having problems getting the correct data type into the SetAttribute
method of the ParameterData object.

 

Regards,

 

Pete
