Subject: Error is Object doesn't support this property or method

I am trying to pass a C# string under Vs2005 (Net2) to an Vb6 ActiveX
Control.

I get the following runtime error--
"Object doesn't support this property or method"

Yet the Intellisense shows the following--
axMainViewJ1Obj1.AddFileJ1(ref string str);

Also the project compiles without error.

The Vb6 method is--
Public Function AddFileJ1(FileName As String) As Boolean

Calling it from a test Vb6 Exe program works fine.

The actual code snippet in C# is--
string str=@"G:\Program FilesJ1\Iris\Data\Data\Example 1 - identified and
well separated.rst";
axMainViewJ1Obj1.AddFileJ1(ref str);

Any suggestions would be appreciated.

John,

If you would not get your answer here, I would ask this in the newsgroup
microsoft.public.dotnet.languages.vb

There are more people who did formely use VB6 and which are more familair
with your problem.
(There are in this newsgroup as well some people active who knows that
before you understand me wrong).

The method you get will be almost the same in C# as in VB.Net

Better is not to tell that it is for C# because it is a VB.Net newsgroup.

I did try it without the "ref" and it would not compile. It requires the "ref".

Thanks.

Right, ByRef is defaulut in VB6.

(ref somestring);

should work. Try to remove the referenced axcontrol from VS unregister the
ocx and reregister before adding the reference back.

Thanks for your reply.
I tried that but it did not solve the problem.

I then removed all parameters from the Method to be called from C# (i.e., I
embedded a file name on the Vb6 side, tested on the Vb6 side and it worked).
Even without arguments I get the same error.

The processing inside the Vb6 control takes a few seconds and there is such
a delay when the C# Method is called on the wrapper class before the error is
returned so something is happening inside the control.

This particular Vb6 control uses a number of supporting Vb6 controls some of
which have licenses (which have been installed). I am assuming that if the
control is called successfully from Vb6 (same computer) that everything
should be in its proper place (COM objects registered, etc). So this whole
thing remains a mystery.

In searching the Web I found that the exact wording does occur associated
with just Vb6 App's so it may be not a C# Interop issue but a Vb6 issue YET
it works from the Vb6 side.

I have tried to post this question on the .NET Vb side but the Newsgroup
seems blocked at this point.

Any suggestions would be appreciated.

Thanks again.
