The processName field is static so it only needs to be initialized
once per application domain, during the first connection.
The GetProcessName() method is static to allow access to the static
processName field.
Inside GetProcessName() we check if the processName field is
initialized or not, if not we do the try/catch otherwise we just
return the processName field (no try/catch at every new connection,
only the first one).
I do not know enough about asp.net of compact framework to handle those parts.
private DatabaseParameterBuffer BuildDpb(IDatabase db,
FbConnectionString options)
{
......
dpb.Append(IscCodes.isc_dpb_process_name, GetProcessName());
return dpb;
}
static string processName;
#if (NET_CF)
// for CF we can implement GetModuleFileName from coredll
private static string GetProcessName()
{
if (processName == null)
{
try
{
StringBuilder path = new StringBuilder(1024);
if(GetModuleFileName(IntPtr.Zero, path, path.Capacity) > 0)
{
processName = path.ToString();
return processName;
}
}
catch{}
processName = String.Empty;
}
return processName;
}
#else
private static string GetProcessName()
{
if (processName == null)
{
try
{
try
{
processName =
Process.GetCurrentProcess().MainModule.FileName;
return processName;
}
catch{}
try
{
processName = AppDomain.CurrentDomain.BaseDirectory +
"-" + AppDomain.CurrentDomain.FriendlyName;
return processName;
}
catch{}
}
catch{}
processName = String.Empty;
}
return processName;
}
#endif
