Following this suggestion from the community I wrote an application which basically works, but as I've already written in the comments on the community page, the first time I call OpenRead, it is really slow.
I think this is what described in several web pages (see here, or here, for example).
In the C# examples the solution is to set WebClient.Proxy, but the problem is that I can't find a function to set this inside CVI .NET Wrapper for system.dll.
I see a lot of functions System_Net_WebClient_xxxxxx but I can't find any function to set the proxy.
Could someone help me?
