几个非常有用的函数－获取可执行文件所在的目录及读取配置文件

?

// 取得Exe所在的目录(不包含最后的"\")

CString GetExePath()

{

    char sFileName[256] = {0};

    CString sPath = _T("");

     

    GetModuleFileName(AfxGetInstanceHandle(), sFileName, 255);

    sPath.Format("%s", sFileName);

    int pos = sPath.ReverseFind('\\');

    if(pos != -1)

        sPath = sPath.Left(pos);

    else

        sPath = _T("");

     

    return sPath;

}

 

void ReadKeyValue(LPCSTR lpSection, LPCSTR lpKey, LPCTSTR lpDefault, CString &sDest, LPCTSTR sConfigFile)   // 读取字符串

{

    char sValue[500] = {0};

    GetPrivateProfileString(lpSection, lpKey, lpDefault, sValue, 499, sConfigFile);

    sDest = sValue;

}

 

void ReadKeyValue(LPCSTR lpSection, LPCSTR lpKey, int nDefault, UINT &nDest, LPCTSTR sConfigFile)           // 读取整数

{

    nDest = GetPrivateProfileInt(lpSection, lpKey, nDefault, sConfigFile);

}

 

void ReadKeyValue(LPCSTR lpSection, LPCSTR lpKey, int nDefault, BOOL &nDest, LPCTSTR sConfigFile)           // 读取BOOL数据

{

    UINT nTemp;

    nTemp = GetPrivateProfileInt(lpSection, lpKey, nDefault, sConfigFile);

    nDest = nTemp != 0;

}

若有需要，再添加对这几个函数的声明：

?

CString GetExePath();

void ReadKeyValue(LPCSTR lpSection, LPCSTR lpKey, LPCTSTR lpDefault, CString &sDest, LPCTSTR sConfigFile);

void ReadKeyValue(LPCSTR lpSection, LPCSTR lpKey, int nDefault, UINT &nDest, LPCTSTR sConfigFile);

void ReadKeyValue(LPCSTR lpSection, LPCSTR lpKey, int nDefault, BOOL &nDest, LPCTSTR sConfigFile);
