Input Tips Every Day 源程序
新近把Input Tips改动了一下,使用ACCESS的文件来存取每天输入的Tip， 所以就把原来的2.0的源程序放上来，请您多指点，以改进，学习。
第一件事当然是利用VC的MFC AppWizar成立一个DIALOG based 的应用程序了, 会自动生成一个CAboutDlg, 一个App, 一个Dlg.我在第一个类里加了一个OnHelp(), 这样你在AboutDlg里点一下那个图标就能打开HELP.HTM,参见程序. 在CTipApp::InitInstance()里加了一句话,
CTipDlg dlg;
m_pMainWnd = &dlg;
if (m_lpCmdLine[0] == _T('\0'))
dlg.pFileName = "Tips.TXT";
else
dlg.pFileName = m_lpCmdLine;
int nResponse = dlg.DoModal();
把输入参数转化成pFileName,实现多用户使用不同的存储文件的功能。
以下的事情都是在CTipDlg中进行了.在资源编辑器里把那个缺省的DIALOG改成
上面的按纽我分别起ID为:ID_PREVIOUS, ID_NEXT, ID_DELETE, ID_RECORD, IDC_Tips(那个大的编辑框), IDC_TIME, IDC_INDEX. 然后对应每个按纽 在CLASSWIZARD加上CLICK的函数.
下面是TipDlg.h,定义了所有的成员函数，灰色的那段都是 CLASSWIZARD加的,
