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

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

Thanks.

| 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.
