VC 写的定时器 计数器示例程序，定时器响应函数（在SetTimer()函数的最后一个参数可以指定一个回调函数，没有指定时采用默认的回调函数OnTimer()），变量声明必须在“{}”中。如图所示的例子中，左侧为定时器，右侧为计数器，点击相应的控制按钮可测试对应功能。-VC wrote timer counter sample program, the timer response function (in SetTimer () function is the last parameter can specify a callback function, using the default when you do not specify a callback function OnTimer ()), the variable declaration must be in "{}" the. As shown in the example, the left side of the timer on the right side of the counter, click the appropriate button to test the corresponding control functions.
