Hi there. I'm dealing with the message errors: "an unexpected error occurred on a send" / "an unexpected error occurred on a receive". I'd like to know what does happen when the WebService i'm calling is being invoked. In order to achieve this, is there any tool (either in VS.Net or from third party) that allows me to make this "trace"? Thanks.

Joseph,

Are you the owner of this web service that is being called?

If so, you can step through the code as it is being executed.

hi,
 i am new to this forum. i have a peculiar problem with Web services and interop. i created a web service application(server). I generated the SErver STub code from WSDL Generator Tool. this tool creates a .cs file which contains server stub code. i included this file in my project and that becomes my Web server. Apart from this whenever i get a function call from client, i just call the functions in a COM dll ( which i included through references). When I call the API in the dll, from the server, i am sending a structure as parameter, by ref. but when this api returns, the structure should be filled up, but this is not happening. Are there any formattings to be done before/after calling. can u please tell me if u know anything about this.
