Read/Write Custom Properties Without Opening Files

Hi All,

I'm trying to export and then re-import SW custom properties through an MS Excel interface without having to actually open the SW files.  In case anyone's wondering, the reason why I need it to be through Excel is because I need to cross-reference against another spreadsheet in order to figure out which custom property value I want to be re-imported.  I already have some VBA code written that will allow me to do the export/re-import, but it requires me to actually open the SW files in order to do so.  Since I have thousands of files to go through, some of them rather large, I'm looking for a way to avoid this step.

I've already googled the subject and all arrows are pointing to the DSOfile.dll, which supposedly will allow me to make the changes I want without actually opening any files.  I got to the point where I installed the dll and added it to the references in VBA.  However, I don't know what the VBA syntax is to actually read/write to the custom properties.  For example, if I had the SW file open, my VBA code would just look like: CP value = Model.GetCustomInfoValue("", PropertyName).  Does anyone know what the "equivalent" code would be using the DSO library?

Thanks,

Sally
