WritePrivateProfileString函数写ini文件时,有时候速度特慢,不知道为什么!!?

程序如下:

WIN32_FIND_DATA FindFileData;
HANDLE hFind;
hFind = FindFirstFile(g_ModelNodeInfo.m_pcDBBackupFile, &FindFileData);
if (hFind == INVALID_HANDLE_VALUE)
{

WritePrivateProfileString("WasteNO","MinWasteNO",pcWasteNo,g_ModelNodeInfo.m_pcDBBackupFile);
} else
{
FindClose(hFind);
}

try

WritePrivateProfileString(pcSession,"VEHICLE_CLASS",_itoa(g_ModelTollInfo.m_TollWasteBook.m_nVehicleClass,pcBuf,10),g_ModelNodeInfo.m_pcDBBackupFile);
WritePrivateProfileString(pcSession,"VEHICLE_CASE",_itoa(g_ModelTollInfo.m_TollWasteBook.m_nVehicleCase,pcBuf,10),g_ModelNodeInfo.m_pcDBBackupFile);
WritePrivateProfileString(pcSession,"VEHICLE_WEIGHT",_itoa(g_ModelTollInfo.m_TollWasteBook.m_nLoad,pcBuf,10),g_ModelNodeInfo.m_pcDBBackupFile);

WritePrivateProfileString(pcSession,"TOLL_RECEIVABLE",_itoa((int)g_ModelTollInfo.m_TollWasteBook.m_fTollReceivable,pcBuf,10),g_ModelNodeInfo.m_pcDBBackupFile);
WritePrivateProfileString(pcSession,"TOLL_ACTUAL",_itoa((int)g_ModelTollInfo.m_TollWasteBook.m_fTollActual,pcBuf,10),g_ModelNodeInfo.m_pcDBBackupFile);

WritePrivateProfileString(pcSession,"RECEIPT_NO",g_ModelTollInfo.m_TollWasteBook.m_pcReceiptNO,g_ModelNodeInfo.m_pcDBBackupFile);

swprintf(pwcbuff,L"%hs",g_ModelNodeInfo.m_pcDBBackupFile);
WritePrivateProfileStringW( NULL, NULL, NULL, pwcbuff);

return(0);
}
catch(...)

不至于这么慢吧？如果完整的程序，我可以晚上抽时间调试下看看。

我现在改成了以流文件形式写,应该会好一点吧!

程序如下,多提意见:

ofstream DBBack;
DBBack.open(g_ModelNodeInfo.m_pcDBBackupFile, ios::app | ios::app);

sprintf(pcBuf,"%d",m_nTableTollWasteNO);
DBBack<<"["<<pcBuf<<"]"<<endl;

sprintf(pcBuf,"%d",g_ModelNodeInfo.m_nNetID);
DBBack<<"NET_ID="<<pcBuf<<endl;

sprintf(pcBuf,"%d",g_ModelNodeInfo.m_nStationID);
DBBack<<"STATION_ID="<<pcBuf<<endl;

sprintf(pcBuf,"%d",g_ModelNodeInfo.m_nNodeID);
DBBack<<"NODE_ID="<<pcBuf<<endl;

sprintf(pcBuf,"%d",g_ModelNodeInfo.m_nNodeType);
DBBack<<"NODE_TYPE="<<pcBuf<<endl;

优化一下 ...

每次WritePrivateProfileString都需要打开文件，读取，查找键，重写整个文件。

网上有很多优化的替代。 先在内存中处理好， 最后写整个文件。

记得有工具软件写ini

只写:0101010101011101011100001001011010...

这样就快了。

不过，可读性几简乎为0

再嫌慢就用XML
