    CRecordset::Open() is throwing an exception

    Hi,
    I'm trying to fix a program that interacts with a database, and while stepping through in debug mode I see that the line in red is throwing an exception.
    CustomerPlatform is derived from CRecordset.
    The MSDN isn't very clear on what exactly could cause CRecordset::Open() to throw other than:

    If snapshot isn't supported, then I don't know how this ever worked in the past since that's what all cases use...
    Code:
    	else if (CustomerPlatform* tmpRecSet = dynamic_cast<CustomerPlatform *>(recSet))
    	{
    		tblName = tmpRecSet->GetDefaultSQL();
    		recName = "Platform ";
    
    		tmpRecSet->m_strUniqueIDParam = inRec.GetUID();;
    		tmpRecSet->m_strFilter = _T("UniqueID = ?");
    
    		tmpRecSet->Open(CRecordset::snapshot); 
    
    		...
    	}
    Any ideas on why it's throwing an exception?

    Nevermind. I fixed it: http://support.microsoft.com/kb/115516/EN-US/
    I don't know how or why, but my TEMP environment variable got messed up...
