Hi, I had downloaded the following sample code that modifies the Preferences->Network from the Knowledge Base with the following subject: Sample code to add/modify network services in the Network panel programmatically. Version 1.1 http://oasis.palm.com/dev/kb/samples/2370.cfm DmOpenRef dbID; LocalID recordNum; UInt16 newRecord; NetworkPreferencesType prefs; PhonePrefType phonePrefs; // dbID - Open Database. // recordNum - Find Record Number. //save the changes in the database. This will change the record position if we change the service name. err = SaveService(dbID, recordNum, &newRecord, &prefs, &phonePrefs); I tried to perform a call to "SaveService" function, but it gives me the error "Non-Free Chunk in Free List" on the Emulator, but not on the Palm V Handheld. I am using Palm OS debug rom v3.5.0 in Emulator Version 3.2. This is compiled in CodeWarrior V.7. Please advise. Help needed ASAP.
