EDB - CeGetDBInformationByHandle

Hello,
I am tring to open some EDB databases... and to get the corect name using CeGetDBInformationByHandle.

My code looks like this:

*hSession = iCeCreateSession(pGuid);
if(*hSession==NULL)
return INVALID_HANDLE_VALUE;

if( (hwnDB=iCeOpenDatabaseInSession(*hSession,pGuid,poid,pwszName,pSort,dwFlags,pRequest)==INVALID_HANDLE_VALUE)
{
DisplayMessage(GetLastError());
return;
}

// DB open
BY_HANDLE_DB_INFORMATION lpDBInfo ;

lpDBInfo.wVersion = 2;// version for EDB
if(!CeGetDBInformationByHandle(hwnDB, &lpDBInfo))
{
DisplayMessage(GetLastError()); // HERE I get sometimes error code 87 (The parameter is incorrect.)
return;
}

if(lpDBInfo.infDatabase.dwFlags |= CEDB_VALIDNAME)
DisplayMessage(lpDBInfo.infDatabase.szDbaseName);

Could anyone tell me why this is happening ?
Best regards.

I tried this, it works fine for me. Do you have the steps to reproduce this?
