One additional thing, this must be an UNMANAGED exmample as this third party dll is not at all complient with manged classes

<div>
<div class="content wysiwyg-content">
Please help. &nbsp;I am proficent in C# and the new microsoft .net framework, but I have to access a third part dll using com/interop with .net and I am unable to successfully get the results i need from using platform invoke and the third party dll does not provide a type library so I cannot use the type library importer tool.<br />
<br />
I can however create all my logic in C++ and then create a RCW to allow me to acces my new object in C#, but I have never ever create a true c++ com object or dll and don't know where to begin.<br />
<br />
Can someone please point me in the right direction whether it be books or web examples. &nbsp;All I need is a simple example and I can move foreward.<br />
<br />
Thanks<br />
<br />

First C++ COM Object

Most development for the Microsoft platform is done utilizing the technologies supported by the.NET framework. Other development is done using Visual Basic for Applications (VBA) for programs like Access, Excel, Word and Outlook, with PowerShell for scripting, or with SQL for large databases.

Microsoft Development

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
