调用Sub与假按键 [英] Call Sub vs. fake a key press
问题描述
首先，主题可能没有使用正确的术语，但我不确定
在VB中调用它是什么。
我正在写一个媒体播放器应用程序。处理打开文件的子程序
按钮包含一个If语句，用于查看文件是否已经在播放，以及
因此执行一些代码来停止前一个文件从其他
之类的东西中玩。还有一个停止表单上的按钮包含确切的
相同的代码。显然，如果只有一个子程序包含代码，那么将会更容易，并且可以从打开的
例程和停止例程中的If调用该子程序。我的问题是，是否有一种方法可以使程序认为停止。按钮被按下了？ I.E.是否有任何
语句我可以将其放入打开文件中的If语句中这将是
" trigger"就像停止一样按钮被按下了？如果是这样的话，
有没有任何警告可以在程序中伪造一个按钮点击而不是
只是将代码放在一个sub中并从两个事件中调用它？

First, the subject probably doesn''t use the correct terms but I''m not sure
what it''s called in VB.
I''m writing a media player app. The subroutine that handles the "open file"
button contains an If statement to see if a file was already playing and if
so executes some code to stop the previous file from playing among other
things. There''s also a "stop" button on the form that contains the exact
same code. Obviously it would be easier if there was just one subroutine
containing the code and that sub would be called from the If in the open
routine and from the stop routine. My question is, is there a way to make
the program think the "Stop" button was pressed? I.E. is there anything
statement I can put in the If statement in the "open file" sub that will
"trigger" just the same as if the "stop" button had been pressed? If so, are
there any caveats to faking a button click from within the program versus
just putting the code in a sub and calling it from both events?

你可以像以下一样打电话给：
MyButtonPressEvent（我，没什么）
唯一的问题是你的事件arg参数将为空 - 除非当然
你也通过了eventarg。
