Hey all, I'm adding a C++ COM dll as a reference to a C# project (Visual Studio 2008). VS adds the reference however the generated interop library does not reflect the naming in the original typelib (.idl) definition. Here's what my library definition looks like: [ uuid(...), helpstring("MyLib") ] library MyLib { [ uuid(......

Scenario: A publically available Web Service that I have full control over. But I only want this specific desktop application (my published application) to have access to the Web Service. I could store a secret password in the desktop client, but that would be easy to crack. Is there any known implementation that enforces this? PKI, as...

So I'm still struggling with the sucky fact that if you make a .net user control deploy as a .dll file to embed it in IE you have to have the user add the site as a trusted site AND modify their .Net security settings. If I don't do the above two things (add trusted site and modify .Net security settings) I get a http response 206 when ...

This question has been asked before, but I never found a truly satisfying solution - I have a class library written in C#, and I want to call it from a legacy native C++ application. The host application is truly native, compiled on Windows & Linux, its a console application. So how can I make it call the C# class library, assuming usin...
Some background: I used Visual Studio quite a bit back in the pre-.Net days, and I'm now moving towards using it again. In the interveining years, I've been doing a lot of coding in other environments (Java, Python, Perl, C++, embedded C, lots of HTML/CSS/Javascript, etc) as well as a fair amount of .Net work that just didn't use Visual...
I'm getting so so close to deploying my .Net dll user control in IE, somebody suggested trying to package it inside an msi file (instead of directly linking to the dll in the object tag) so that the user gets the trust prompts. So I followed the directions here: http://social.msdn.microsoft.com/Forums/en-US/winformssetup/thread/8ddd0fd...
Say I have a Date, or a Phone number, or some Class which I don't actually want to store as a string at runtime, but which could have a nice short string serialization for serialization as a XAML attribute: <Person PhoneNumber="+1-123-123-1234"/> How do I make my type serialized in that representation? ...
