Webservice call from extended stored procedure

[Guest]

I'm trying to write an extended stored procedure that will call a webservice
First I wrote a console application and made the call

localhost::WsXpService* xsp = new localhost::WsXpService()
String* s = String::Copy(xsp->WsXpMethod2())

This works fine
But when I put the same code (same reference) into my XP procedure code I cannot even compile it?
What's wrong?

Hi Folke,

I'm trying to write an extended stored procedure that will call a webservice.

What's wrong??

What errors do you get?
How did you start/create your XP procedure project?

Bye,
SvenC

Did you enable "Use Managed Extensions" in your general project properties?
Did you add a "Web Reference" to the WebService? If yes, is the resulting
code ATL or CLR based? You can verify this by looking at the proxy in the
generated header: Is there an #include of <atlsoap.h> or using namespace
System::Web::Services?


HTH,

Sven!
Thanks for all your help. The code below now compiles:
localhost::WsXpService* xsp = new localhost::WsXpService();
System::String __gc* gcstr;
gcstr = System::String::Copy(xsp->WsXpMethod2());
Not sure why I have to put th __gc after System::String ?? (Can I only have data on the managed heap?)
Now I'll try to get it to work at run-time!
