Commamd1执行一个费时的操作，包括调用多个过程和函数，而Command2则是终止/暂停Command1的运行，不是退出该程序，不知用VB5.0如何解决?答：你可以采用一种变通的方法，在程序中定义一个Boolean变量，在执行command1中的程序时监视该变量，如果为False退出程序，在command2中加入代码，只要点击command2就将该变量设置为False下面是例程DimbMarkAsBooleanPrivateSubCommand1_Click()bMark=TrueForI=1To150000'Startloop.DoEvents'Yieldtooperatingsystem.Text1.Text=Str(I)IfNotbMarkThenExitSubEndIfNextI'IncrementloopcounterEndSubPrivateSubCommand2_Click()bMark=FalseEndSub问：有位大侠编了如下代码:PrivateSubcmdCalendar_Click()DimUserDateAsDateUserDate=CVDate(txtDate)IffrmCalendar.GetDate(UserDate)ThentxtDate=UserDateEndIfEndSub
