Calling a C# dll with vb6

Hi all!

I'm really new to vb6 and have some knowledge of C# and would like to create a vb6 program that calls a C# dll but I've found a huge problem which is, I always get a "dll runtime error 453".

I've been googling for some hours and can't find the solution for this problem...

please help.

thanks a lot

(here's the code sample... it's just an example)

Private Declare Function func Lib "C:\Documents and Settings\...\dllnewAtt.dll" () As String

Private Sub Command1_Click()
Dim nSpeed As String

nSpeed = func()

Form1.Text1.Text = nSpeed

End Sub

Just out of curiosity, why are you moving back from .NET to VB6?

the company where I'm working at, asked me to customize some software that is written in VB6... they'r trying to update everything to C#.Net but they asked me to change a program and I have 1week to make that change... so as I don't have time to re-program 10thousand lines of vb6 code to C# in a week's time, I decided to call newly created C# functions inside the VB6 code.

Anyway, I solved my problems today too, so all is good!

bye!

Perhaps posting up your solution so others that search can benifit from it. ;)

yes... good Idea... It's not that simple, but if you follow the steps that are shown in the following link, then you will be able to call a C# dll in a vb6 program successfully

Private Declare Function func Lib "C:\Documents and Settings\...\DllSuccess.dll" () As String

Private Sub Command1_Click()

Set aux_obj = CreateObject("DllSuccess.Class1")
x = aux_obj.returnstring()
Form1.Text1.Text = x

End Sub

this worked!
