First, learn to interpret OS error codes. They always consist of a round (in hex) base code that indicates the subsystem, plus small sequential numbers for the specific error. In this case, 528 should jump out as looking like 512 + 16, or 0x200 + 16. And sure enough, the SDK header files reveal these definitions: // file ErrorBase.h #define dmErrorClass 0x0200 // Data Manager // file DataMgr.h #define dmErrResourceNotFound (dmErrorClass | 16) So something in SysAppLaunch is failing to find some resource. Without the OS source that's not very specific, but good to know. So let's look for problems in your first piece of code: > In order to get the cardNo and dbID for iMessenger, I do: > err = DmGetNextDatabaseByTypeCreator( true, &searchState, > 0, sysFileCMessaging, ... ); You pass zero for the database type to find. This tells it to return the first matching database with iMessenger's creator ID. This might just work and find the iMessenger application, but it might find some other database that has the same creator ID instead. In fact that's what is happening here. It finds iMessenger's 'DATA' database instead. (Or on 3.5 it may also find the resource overlay DB.) Then when you try to SysAppLaunch it, the OS can't find a code resource in it, so SysAppLaunch fails and returns dmErrResourceNotFound. The fix: pass sysFileTApplication ('appl') instead of 0 to DmGNDBTC. -slj- -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
