问题描述

我想要一个停车场预订系统，我把picbox让用户点击，我的问题是如何使用picbox连接到sql 2014，我的意思是我需要知道用户点击了哪个picbox，它会自动记录到sql 2014.



我尝试过：



私有子PictureBox10_Click（发件人为对象，e为EventArgs）

如果CType（发件人，PictureBox）.Image可用，则说明

CType（发件人，PictureBox）.Image = provisionalIcon

ElseIf CType（发件人，PictureBox）.Image是provisionalIcon然后

CType（发件人，PictureBox）.Image = availableIcon



结束如果

结束Sub

i want to a car park booking system, and i put picbox to let user click, my questions is how to use picbox to connect to sql 2014, i means i need to know which picbox the user have clicked, and it will auto record to sql 2014.

What I have tried:

Private Sub PictureBox10_Click(sender As Object, e As EventArgs)
If CType(sender, PictureBox).Image Is availableIcon Then
CType(sender, PictureBox).Image = provisionalIcon
ElseIf CType(sender, PictureBox).Image Is provisionalIcon Then
CType(sender, PictureBox).Image = availableIcon

End If
End Sub

推荐答案

使用 sender 参数 - 它会告诉你单击PictureBox的实例，如果你有多个图片框都由同一个事件处理程序处理。



如果你有每个都由一个单独的方法处理，如代码中的方法名称所示，那么你已经知道点击了哪个盒子，因为它将转到一个特定的方法！



至于您的SQL问题，如果您需要帮助，则需要提供更多信息！

Use the sender parameter - it tells you the instance of the PictureBox that was clicked, if you have a number of picture boxes all being handled by the same event handler.

If you have each one being handled by a separate method as the method name in your code implies, then you already know which box was clicked, because it will go to a specific method!

As for your SQL problem, you will need to provide a whole load more info if you want help with that!
