Hello Achim, thank you for your answer. I will try to describe my purpose : As we are not able to translate our .NET DLL through a contextual layout, we developed a tool allowing us the display and copy the 'StringID' or 'Path(=RESX Name)+StringID' into our applications  while reviewing the translation (Information copied to the clipboard). Thanks to this information, we are able to easily find/identify the string (if unique) ('String ID' in Passolo) or using the path ('Resource ID' in Passolo) into our Passolo project with search tool.

I would like to improve the search using the user-defined properties. I imagine we could concatenate the following data : "\Ressource ID\StringID" (corresponding to the information format provided by our application). So then, we could manage Passolo in command line to open it on the right resource to review directly. I hope it helps your to understand. So let me know if you have any comment/recommendation to manage this please.

It would be helpful to get some more information about which custom properties you would like to search. As custom properties might be user defined there is no simply method to search them, but it is very easy to create a Filter that just displaye the searched entries.
