hello,

I have created an interop assembly in C#.
But I couldn't find any way to export helpstrings to the generated typelib
for this assembly.
Which ways have I to do this?

Thanks for your time and any suggestions.

Best regards
Detlev

Hello,

From your post, my understanding on this issue is that you are to export
helpstrings to the typelib generated from an interop assembly in C#. If I'm
off base, please feel free to let me know.

To export helpstrings to tlb, you may consider setting the attribute:
[System.ComponentModel.Description("just for test helpstrings")]
for the methods exposed.

Here is my test code:
using System;
using System.Collections.Generic;
using System.Text;
using System.Reflection;
using System.Runtime.InteropServices;

[assembly: Guid("efe72271-546a-4095-ba7a-b1a64264e1cb")]
[assembly: AssemblyVersion("1.0.0.0")]

namespace NETAssembly
{
[InterfaceType(ComInterfaceType.InterfaceIsDual), ComVisible(true)]
public interface ITest
{
[System.ComponentModel.Description("just for test helpstrings")]
string HelloWorld();
}
[ClassInterface(ClassInterfaceType.None), ComVisible(true)]
public class TestClass : ITest
{
public string HelloWorld()
{
return "Hello World!";
}
}
}

1. Save the above code into a cs file (*****.cs)
2. Run ¡°csc /t:library *****.cs /keyfile:key.snk in .net 2.0 SDK cmd line.
3. Run tlbexp *****.dll /oututfile.tlb to get the tlb file.

Please let me know if you have any other concerns, or need anything else.

Have a nice day!

Hello Jialiang Ge,

thanks for your advice.
U have understand my post right.
That sample works.
But my interface definition includes properties, and I want to have for the
propget and propput method in the typelib different helpstrings.

I add my code to your test code to explain my intention:
using System;
using System.Collections.Generic;
using System.Text;
using System.Reflection;
using System.Runtime.InteropServices;

[assembly: Guid("efe72271-546a-4095-ba7a-b1a64264e1cb")]
[assembly: AssemblyVersion("1.0.0.0")]

namespace NETAssembly
{
[InterfaceType(ComInterfaceType.InterfaceIsDual), ComVisible(true)]
public interface ITest
{
[System.ComponentModel.Description("just for test helpstrings")]
string HelloWorld();

string MyTestProp
{
[System.ComponentModel.Description("MyTestProp get")] // in
typelib will this eported for both, get and set
get;
[System.ComponentModel.Description("MyTestProp set")] //
this won’t be exported to the typelib
set;
}
}
[ClassInterface(ClassInterfaceType.None), ComVisible(true)]
public class TestClass : ITest
{
public string HelloWorld()
{
return "Hello World!";
}

public string MyTestProp
{
get
{
return m_MyTestProp;
}
set
{
m_MyTestProp = value;
}
}

private
string m_MyTestProp = "";
}
}
My question is how can I export the helpstring for the set (propset) method?
Thanks for your time and help.

Best regards
Detlev

Hello

I don't think Property's helpstring can be divided: one for propget,
another for propput.
If you see the VB Properties through object brower, you will find them have
only one helpstring.
For instance: the helpstring of Form's property 'Appearance' is:
Property Appearance As Integer
Member of Unknown1._Form
Returns/sets whether or not an object is painted at run time with 3-D
effects.

Therefore, I suggest that you write 'Returns/sets ...' as description of
property if it has both set and get methods.

Mathias, any idea?
