Document Code change to trigger rename Document Name

Question

The filename already changes when the document name is changed but I need the document name to change when the document name is changed. 
 I assume I'll need to create a custom module with a post trigger on the Doc code written in C++ and register the module. Then add the dll to everyone's PWE. 
 Looking for guidance here as I normally write external programs in VB.NET.

See if setting a post hook on AAHOOK_CODE_GENERATION_DLG is what you need. I suspect that this hook only "fires" if you are using the Document Code Dialog. 
 If you are setting the Document Code via API functions,then I suspect that AAHOOK_UPDATE_LINK_DATA may be the approach that may work for your needs. 
 You may want to review the HookImpl sample code included with the ProjectWise SDK as it sets up a pre, action and post hook which you can use as a "starting" point for your efforts.

Kevin, looking at the documentation for AACODEGENDLG_PARAM, it looks to me that all that is passed for the hook event are arrays of various properties for the documents and their attribute rows. 
 
 That's pretty typical of the kind of information that is passed for a hook. Just enough for you to go get any other information that you are interested in. I'm sure this approach was taken for performance reasons. 
 I suspect that what you need to do is first determine if the environment for the document(s) that you are interested in has document coding enabled, and if so then determine which document attribute column is the "place holder", and then you can select that document (or attribute row) to get the value.

Google or Bing (or other search engine?) is your "best friend" for questions like this. Try entering text similar to the following into your favorite search engine: 
 site:microsoft.com c++ get file extension 
 The function I typically use to get the parts of a file's device, path, name, and extension is a one of the variations of "splitpath()". 
 The ProjectWise SDK includes some "File System Handling Functions" including variations of aaApi_SplitPath(). Note that the first two variations have been deprecated, so use aaApi_SplitPath3() as it can handle multiple dot extensions. 
 
 As for how to concatenate two strings, well there are various methods. I tend to use Microsoft's MFC framework, which has the CString class, but you can also do it the "C" way, or use one of the various methods that you can find with a search for "C++ concatenate strings". 
 You might consider looking into some online training for C++ as there is much available, and a lot of it is free.
