I’ve been using the macro from this blog entry for attaching the Visual Studio

  • 0

I’ve been using the macro from this blog entry for attaching the Visual Studio debugger to an already running instance of the Web Application I’m currently working on. However, if I have more than one instance of the Visual Studio web server running it’s pot luck which one it’ll attach to.

Is there a way to determine what port is configured in the Web project so I can modify the macro to filter its choice of process to that one?

Further Info

I’m aware that you can set the port number to a static one – I’ve done just that from the get-go, what I’m trying to determine is how to programatically determine the defined port-number so I can modify the macro (in the linked blog entry) and ensure it connects to the right instance of the Visual Studio web server.

The way I have things running is I have two (or more) instances of Visual Studio running, each of which contains a Solution, which contains a web project and one or more other projects – typically an Installer project), so when I trigger the macro from a given instance of Visual Studio, I want to find the Web Project within that instances loaded solution and determine the port it’s running against.

  1. If that can help you, I have found a link that might actually to the trick.

    However, it require DllImport call and a lot of fun.

    You can take a look at that article there: http://bytes.com/forum/thread574901.html

    Quotes from the actual site:

    By calling into iphlpapi.dll using PInvoke interop. Google around for GetExtendedTcpTable and iphlpapi.dll, I’m sure you will find some existing stuff.

    Willy.

    And one last:

    Here are some API-Methods for my purposes:

    GetTcpTable()
    AllocateAndGetTcpExTableFromStack()
    GetExtendedTcpTable()

    I wrote a small programm that is able to show me all Processes with the belonging TCP-Ports (with AllocateAndGetTcpExTableFromStack()) running under Windows XP.

    Now my problem is, that under Windows 2000 I can’t use AllocateAndGetTcpExTableFromStack() or GetExtendedTcpTable() so I’m only able to use GetTcpTable() to list all TCP-Ports but without the belonging processes.

    Did somebody have the same problem or is there another way (.Net or WMI etc.) to solve my problem?

    Thanks in advance,

    Werner
