If the program being disassembled has a companion PDB file, then this command may be used to load information from the PDB file into the database. By default IDA uses in-house code to parse and load PDB files. However, our code can not parse old v2.0 PDB files. For them, IDA can fall back to using Microsoft DLLs (the default is "do not fall back"). Please read more in cfg/pdb.cfg. Command line switch `-Opdb:option1:option2` overrides for ida session the value in cfg/pdb.cfg. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.hex-rays.com/ida-actions/loadpdbfile.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
