Re: Calling COM functions using IDispatch->Invoke(...

Hi, Sven

May be something is fundamentally wrong with this COM server, I mean
this third party gave me example of the code not just in VB, but in C#
also:

Example 1:

static void Main(string[] args)
{
  using(DispatchObject comObj = new
 
DispatchObject("SomeCOM.SomeInterface"))
  {
     comObj.InvokeMethod("Start", @"C:\\..path");

   //exception thrown

Examle 2:

object comObj = null;

try
{
   comObj = System.Activator.CreateInstance(
         Type.GetTypeFromProgID("SomeCOM.SomeInterface", true));

   comObj.GetType().InvokeMember("Start",
 
System.Reflection.BindingFlags.InvokeMethod,
                                                    null,
                                                    comObj,
                                                    new object[] { @"C:
\\=85path " }
                                                  );

     //exception thrown

I.e. even the examples in C# they provided, do not work =96 the program
crashes, though example in VB works fine ?! The only thing I've
noticed, both their examples in VB and C# using only one parameter
=93Path=94 for this method =93Start=94, though as I've mentioned at the ve=
ry
beginning prototype, that I can see in .tlh file has two parameters=85
But I've tried already use only one parameter in dispparams structure,
the result is the same=85

Anyway thanks again for trying help me,

Alex
