Class Library

[Luis Gustavo]

Good afternoon.

I would like to know if is possible use a dll made in Vb.net in VB 6.

I made this to test the dll:

Imports System.Data

Imports System.Xml

Public Class RH

Public Shared Function addHistory(ByVa l txtFind As String, ByVal txtReplace
As String) As String

Return "Luis Gustavo Aleixo"

End Function

End Class

the code is rigth, when I try to register with the command "regsvr32" happen
a error:
"---------------------------
RegSvr32
---------------------------
ReplaceHistory. dll was loaded, but the DllRegisterServ er entry point was not
found.

DllRegisterServ er may not be exported, or a corrupt version of
ReplaceHistory. dll may be in memory. Consider using PView to detect and
remove it.
"
What I need to make to use the dll in VB 6?

Add this Code
<ComClass(Rythm ia.ClassID, Rythmia.Interfa ceId, Rythmia.EventsI d)> _
Public Class Class1
#Region "COM Class IDs"
Public Const ClassID As String = "5F0D4112-B23D-4703-94F5-B5B96E50F3BB"
Public Const InterfaceId As String =
"A9DFEE4E-3DBB-4505-BBC6-9BCEE5A220A5"
Public Const EventsId As String = "E6CAB551-4A34-4c4d-83EA-7D3D7E2E49DF"
#End Region
Sub Main()
End Sub
End Class

This makes your DLL emulate an ActiveX control. From here, you can register
it, or select the option in the project properties to register it for COM
interop. One thing to remember about the ID's, you need to use the utility
"Luis Gustavo" <lg****@nsb.com .br> wrote in message guidgen, and select
Registry Format. Otherwise, should work just fine.

You probably already know that VB6 can create and use COM/ActiveX DLLs or
use "standard" DLLs. As VB.Net creates managed assemblies they are based on
(completely) different techniques. However, you can also create COM Interop
wrappersin VB.Net. An entry point is here:

http://msdn.microsoft.com/library/en...sicVisualC.asp

http://msdn.microsoft.com/library/en...nentstocom.asp

http://msdn.microsoft.com/library/en...alBasicNET.asp
You'll also find these (and from there other topics) in the <F1> docs.

I need to make one minor correction, in this portion:
<ComClass(Rythm ia.ClassID, Rythmia.Interfa ceId, Rythmia.EventsI d)> ;
Rythmia is the name of my class, so it should read Class1 in this example.

Not to forget type library guid:

<Assembly: Guid("6489269F-2E92-448B-96AF-A9C70B7C8E71")> in file
AssemblyInfo.vb

Your class must always have a public parameterless constructor. Constructors
with parameters or shared properties/methods/fields are not accessible.

You may use Regasm.exe to create type libarary, reg file or install your
assembly on client machines. But be careful what you expose to Non.NET
world!

Luis,

You should not use regsvr32! Forget about it completely in .NET world!
I have a sample retg file in the office that I will send you tomorrow. But:

1. Why do you have two assembly GUIDs? See:

'<Assembly: Guid("E8C42458-4ED8-4485-8145-A364D099BC5B")>

<Assembly: Guid("6489269F-2E92-448B-96AF-A9C70B7C8E71")>

Only the last one will be used.

2. You have to use codebase switch that points to your assembly while using
REGASM.EXE. Just run regasm.exe /? to get help or use MSDN to see how that
switch works. You also can add the "codebase" registy entry yourself but it
is more prone to errors.

I know these because I spent half of a day finding my way through poor
explanations of MSDN (Sorry Bill Gates!).

Good luck
Ali

On development machine yes but not on production machine... You need to
register the component on the client. I usually create reg file and then
manually edit it (chop off unrelated bits) and then run it on client.
