interop

This is probably trivial, but I can't think of a better way to do it. I have a COM object that returns a variant which becomes an object in C#. The only way I can get this into an int is int test = int.Parse(string.Format("{0}", myobject)) Is there a cleaner way to do this? Thanks Joel Coehoorn You have several options: (int) — Cast operator. Works if the object already is an integer at some level in the inheritance hierarchy or if there is an implicit conversion defined. int.Parse()/int.TryParse() — For converting from a string of unknown format. int.ParseExact()/int.TryParseExact() — For

I have a VB6 app that processes for a very, very long time. Killing it directly is not feasible, so I would like to set some sort of flag in the VB6 app. If in my C# app I decide to shut it down, I would like to toggle this flag to let the VB6 app know that a shutdown has been requested. Now, I also need something that is named because there will be several of the VB6 apps spun up as activex exes. Does anyone have any idea how to implement something like this? The workflow follows below C# app - Spin up mulitple VB6 activex.exes in separate threads, Initialize the app with something

Does anyone have some code that will take a TimeZoneInfo field from .NET and execute the interop code to set the system time zone via SetTimeZoneInformation? I realize that it's basically mapping the TimeZoneInfo members to the struct members, but it does not appear obvious to me how the fields will map exactly or what I should care about beyond the bias. BigBlackDog I don't know if this is what you are looking for, but there is some information on how to use the Win32 functions to get and set the timezone information at http://www.pinvoke.net/default.aspx/kernel32/GetTimeZoneInformation.html

There is an insightful question about reading a C/C++ data structure in C# from a byte array , but I cannot get the code to work for my collection of big-endian (network byte order) bytes. (EDIT: Note that my real struct has more than just one field.) Is there a way to marshal the bytes into a big-endian version of the structure and then pull out the values in the endianness of the framework (that of the host, which is usually little-endian)? (Note, reversing the array of bytes will not work - each value's bytes must be reversed, which does not give you the same collection as reversing all of

I'm running into the classic scenario where, when creating Word COM objects in .NET (via the Microsoft.Office.Interop.Word assembly), the WinWord process won't exit even though I'm properly closing and releasing the objects . I've narrowed it down to the use of the Word.Documents.Add() method. I can work with Word in other ways without a problem (opening documents, modifying contents, etc) and WinWord.exe quits when I tell it to. It's once I use the Add() method (and only when adding a template ) that the process is left running. Here is a simple example which reproduces the problem: Dim word
