我正在使用ADO從excel文件中獲取表標題列名稱。問題是數據被返回排序。我需要它的原始順序。這是代碼:從ADO獲取未排序的記錄集
_RecordsetPtr pSchema->m_pCon->OpenSchema(adSchemaColumns);
// pSchema->Sort = ""; // Does not help
// pSchema->Sort = "ORDINAL_POSITION"; // Crashes
while (!pSchema->GetadoEOF())
{
string sheetName = (char*)(_bstr_t)pSchema->Fields->GetItem("TABLE_NAME")->Value.bstrVal;
if (sheetName == "MySheet")
string column = (char*)(_bstr_t)pSchema->Fields->GetItem("COLUMN_NAME")->Value.bstrVal;
pSchema->MoveNext();
}
我該如何使它返回未排序?
