使用wintab开发的例子，VB开发环境，经过验证可以(Wintab32.dll Demo in VB6 ReadMe notes ******************************************************* ******************************************************* A few notes on this before you play with it: 1) You cannot debug through much of the code! The reason for this is that the routine performs a Windows message hook for the window messages that normally go to the window. So when the user moves the mouse over a window, Windows generates all the messages and sends them to the window to respond. (examples are "MouseEnterWindow, MouseMove, MouseLeaveWindow"). Note these are different from the VB events which are similarly named but operate within VB, they are instead the actual messages Windows OS uses to respond. This is how windows does all of its GUI. Since a hook has been placed in the code, those messages go to the callback routine and thus get intercepted in the application. In debug, all code execution halts in the VB app. But windows keeps sending the messages to the cal)

VB6.0禁止修改系统时间的源代码，Windows系统时间有时是自动更新的，如果不选择自动更新，可以手动去修改它，但目前有一些流行的恶意程序为了自己软件方便会强制修改系统时间，本程序可禁止用户或程序修改系统时间，虽然主窗口打开后什么也没，但此时你双击右下角的Windows系统时间，弹出面板内修改时间的话，你会发现修改过的时间会自动恢复，无法修改。本程序的用意并不是在于让用户就这么运行着要程序，而是让VB编程者可从代码中提取出有用的代码，作为一个模块来用，实现禁止修改Windows系统时间的功能。(VB6.0 prohibit changes to the system s source code, Windows system automatically updates the time and sometimes, if you do not choose to automatically update, you can manually to modify it, but there are some prevalent malicious software programs for their own convenience will force changes to the system, this program can prevent users from modifying the system or program time, although the main window opens after nothing but time to time you double-click on the Windows system the lower right corner to bring up the panel s modification time, you will find the modified time will be automatically restored, can not be modified. This program is not intended that allows users to program running on so, but let VB programmers can be extracted from the code of useful code as a module to use, modify the Windows system time to achieve a ban functio)

一个VB6消息相关源码下载，截取消息,并将消息交给wndproc过程处理.取消消息截取，结束子分类过程.Module1.bas中，定义全局变量,存放控件标志性数据，wndproc函数就是用来接收子类时截取的消息的，将截取下来的消息存放在msg参数中.检测到消息,就可以加入处理代码。需要注意,如果这儿不加入任何代码,则相当于吃掉了这条消息(A message related VB6 source code download, intercept messages and the processing of the message to wndproc Cancel message interception, ending the process of sub-classification. Module1.bas, the definition of global variables, data storage control signs, wndproc function is used to receive child when class intercepted message, the message will be stored in the interception down the msg parameter. detected a message, you can add processing code. Note that if you do not add any code here, is the equivalent of eating this message)
