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

[Pete Rabjohns]

Working with strings now (after abstracting the OR layer into it's own
class) but integers fail with below.

 

General failure in Web Method

Put an element into the value safearray failed.

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
