Simon Fell > Its just code > Metadata API and Reports

I've seen a few questions on this recently (this is new for v14.0), so i thought I put together a sample of calling retrieve in the metadata file api to fetch a package of all your reports. This is in VS.NET 2005, but should be easy to translate to other environments. The code does the following steps (this is more complex that other cases because Reports don't support Wildcards)

1. Calls the partner api login to get a sessionId and the URL to the metadata API for your username.
2. Creates and configures an instance of the metadata client.
3. Calls ListMetadata to find out all the ReportFolders.
4. Using the list of ReportFolders, calls ListMetadata again to find out all the Reports in those ReportFolders.
5. Uses Retrieve / CheckStatus / CheckRetrieveStatus to fetch a package of the reports, and writes the package out to c:\reports.zip

	    // I added a WebReference of the partner wsdl as sf, and the Metadata WSDL as md
            sf.SforceService svc = new sf.SforceService();
            sf.LoginResult lr = svc.login(args[0], args[1]);

            ms.SessionHeaderValue = new md.SessionHeader();

            ms.Url = lr.metadataServerUrl;
