I'm trying to use RDNZL im my project (for the GUI) and I faced a problem related to COM interop (I think). The symptom is the following: in my assembly for the GUI, I use FolderBrowserDialog to request a directory from the user; however when the dialog appear, the directory tree is not present and the dialog only contains 3 buttons; looking on the web and testing a little, it appears that it's due to the fact that the main program does not use single-thread apartment state (STAThreadAttribute), which is required with some COM components.

While, it's well explained how to set this attribute in a plain C#/C++ application, this is less evident in the context of RDNZL as I don't know where is exactly the "main entry point" for the managed part of the code. In recent version of VC compiler (VC++-2005), there's a /CLRTHREADATTRIBUTE flag to specify it, however I couldn't recompile the RDNZL library with such a compiler, because apparently lot of things have been deprecated since VC++-2003 regarding managed code in DLL.

Would you have any solution for this problem? Thanks.

I don't have an immediate fix for this, so I'm forwarding your question to the RDNZL mailing list - maybe someone there knows what to do.

Cheers, Edi.
