WritePrivateProfileString函数写ini文件时,有时候速度特慢,不知道为什么!!?
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)
{
char pcWasteNo[20];
sprintf(pcWasteNo, "%lu ",m_nTableTollWasteNO-1);
WritePrivateProfileString( "WasteNO ", "MinWasteNO ",pcWasteNo,g_ModelNodeInfo.m_pcDBBackupFile);
} else
{
FindClose(hFind);
}

try
{
int nFlagStation = -1;
COleDateTime CreationTime((time_t)g_ModelTollInfo.m_TollWasteBook.m_nCreationTime);
char pcSession[20],pcBuf[50];
_itoa(m_nTableTollWasteNO,pcSession,10);

if(m_nTableTollWasteNO == (int)GetPrivateProfileInt(pcSession, "WASTE_NO ",0,g_ModelNodeInfo.m_pcDBBackupFile)) return(0);

WritePrivateProfileString(pcSession, "NET_ID ",_itoa(g_ModelNodeInfo.m_nNetID,pcBuf,10),g_ModelNodeInfo.m_pcDBBackupFile);

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

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

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。

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。
