How to: Programmatically detect if MSXML parser (version 3+) is installed or not

Can anyone help me out, how to detect if MSXML parser is installed on a machine or not. I looked for a registry entry,but unable to get one. I am writing a VB.NET application. Thanks in advance :)

Solution

  • One way you can do it is to create an instance of one of the MSXML objects in your code. e.g. 

    Dim t As Type
Dim o As Object
    

    ' If this code causes an exception the object doesn't exist
t = Type.GetTypeFromProgID("MSXML2.DOMDocument")
o = Activator.CreateInstance(t);
System.Runtime.InteropServices.Marshal.ReleaseComObject(o)

    I apologize if my vb.net code is bad :)
