下面是测试demo，使用的是mfc，vs2008,贴出关键代码：
void CCIniTest2Dlg::OnBnClickedOk()//读取ini文件{ // TODO: 在此添加控件通知处理程序代码 CIni out; LPBYTE msg; UINT msgLen; out.GetBinary(_T("entry-1"),&msg,&msgLen,_T("root section")); msg[msgLen]=NULL; ::MessageBoxA(NULL,(char*)msg,"section-1 in entry-1",0);}void CCIniTest2Dlg::OnBnClickedButton1()//写入ini文件{ // TODO: 在此添加控件通知处理程序代码 CIni in; char msg[255]; sprintf(msg,"百度and谷歌"); in.WriteBinary(_T("entry-1"),(LPBYTE)msg,(UINT)strlen(msg),_T("root section")); in.WriteInt(_T("entry-2"),123456,_T("root section"));} |
