// Name: ClearDatabase
//
// Description:
// If requested display a message warning the user that all data in the database
// will be destroyed and give them a chance to answer No. If answer is Yes, then
// use database function to clear any data in the database.
// Note: user must rebuild any structure that is expected in the database
// following this call such as was done by reading names.cfg in previous version
//
// Declaration:
// bool CDbVista::ClearDatabase(const CString &strDbName, bool bPrompt, CString *pstrErrorMsg)
//
// Input: strDbName name used when opened this database
// bPrompt whether to display prompt asking user to clear the db
//
// Output: pstrErrorMsg string containing error message, if any
//
// Return: true (db cleared) / false (db not open or error from db internal -- see pstrErrorMsg)
//
// date / author revision
// ----------------- --------
// 03-Dec-2001 SFK Created from InitializeDatabase in DbGeneralDbSupport.cpp
