Question

用Try_Catch结构，然后再异常除掉用如下函数看看是什么错误void PrintProviderError(_ConnectionPtr pConnection)
{
    // Print Provider Errors from Connection object.
    // pErr is a record object in the Connection's Error collection.
    ErrorPtr    pErr  = NULL;    if( (pConnection->Errors->Count) > 0)
    {
        long nCount = pConnection->Errors->Count;        // Collection ranges from 0 to nCount -1.
        for(long i = 0;i < nCount;i++)
        {
            pErr = pConnection->Errors->GetItem(i);
            printf("Error number: %x\t%s\n", pErr->Number,
                (LPCSTR) pErr->Description);
        }
    }
