[quote user="M k"]My MicroStation VBA knowledge is very basic[/quote]
Then I suggest that you break your project into manageable pieces...
- Figure out how to search for text in MicroStation using VBA
- How to use VBA in one app. from another app. (e.g. Use Excel VBA to control MicroStation)
- Write Excel VBA to send text from a cell to your MicroStation search code
To help with the first task, read this article about Text Search & Replace for MicroStation.
