It's a big professional application with several years of development...
Is there any other way to get a workaround?
Write my own c++ dll, using the stuff and then use my c++ dll inside my VB application?

What a frustrating day...

I thought the dll is usable for VB and C++ and C# ...
So the only difference is how to callt he functions, given by the dll.
Am I wrong with this?

looking at the example I see them using classname and function name.
In other codelines I use
Private Declare Function GetDesktopWindow Lib "user32.dll" () As IntPtr
to get the function out of the dll. So I need a doc, which function I need for what and how to get them.

using
Private Declare Function skpOpenFile Lib "SketchUpReader.dll" Alias "OpenFile" (ByVal filePath As String, ByRef retVal As VariantType) As Integer

gives me the error : entry point not found.
using
Private Declare Function skpOpenFile Lib "SketchUpReader.dll" Alias "ISkpFileReader.OpenFile" (ByVal filePath As String, ByRef retVal As VariantType) As Integer
is the same.

So, how Do I locate the function in the dll?
How Do I include it in my code?

Yes, I did, but it didn't help.

First step is to open a SKP fiel and show it. Later steps is to manipulate and save it.

Yes I did, but it didn't help.
So I'm searchng the Internet.

Hi All

I have to open a SKP file, get the mesh, use it for some mappings and save in my own file format inside my VB.NET application.

All Code Snippets and help is not helpful for me.

Who can help me?
Where can I get some code snippets to see the main structure / functions etc for using the SketchUpReader.dll?

Best regards
