# Thread: Button within a Location to execute a code

1. ## Button within a Location to execute a code

I am getting and error where 80, 380 is and the Comma is getting a error it blatantly says ") expected"

Can someone tell me why it does this?

Code:
```If e.KeyCode = Keys.Space And BtnSprite.Location = New Point(12, 330) <= (80, 380) Then
MsgBox("Txt here")
End If```
Additional info: I wan it if the button sprite is within the location of 12, 330 and 8-, 380 to execute the msgbox. I was confused on how I can implicate between methods but there is none. There is Greater then and less then signs that do the trick.

Neither your code nor your explanation actually makes sense. Presumably you want to know whether the Location of the Button falls within the box described by those two Points as opposite corners. Is that correct? If so then you have two choices:

1. Examine the X and Y components of the Location separately and determine whether they are each within the appropriate range:
Code:
```If e.KeyCode = Keys.Space AndAlso
BtnSprite.Left >= 12 AndAlso
BtnSprite.Left <= 80 AndAlso
BtnSprite.Top >= 330 AndAlso
BtnSprite.Top <= 380 Then
MessageBox.Show("Txt here")
End If```
2. Construct the box and see if it contains the Location:
Code:
```Dim box As New Rectangle(12, 330, 80 - 12, 380 - 330)

If e.KeyCode = Keys.Space AndAlso box.Contains(BtnSprite.Location) Then
MessageBox.Show("Txt here")
End If```

Thanks so much, you professional. The second one was exactly it! Now I want to make the button move faster while holding shift across the form.

My Code:
Code:
``` If Keys.LShiftKey And e.KeyCode = Keys.W Then
BtnSprite.Location += New Point(0, -5) 'Added Location value to W using shift
End If```
Original without shift:
Code:
```If e.KeyCode = Keys.W Then
BtnSprite.Location += New Point(0, -1) 'Added Location value to W
End If```

If you are interested in only horizontal or only vertical then use the Button's Left and Top properties rather than Location. Only use Location if you're interested in both horizontal and vertical. The same goes for Width, Height and Size.

As for the question, it's a bit tricky if you want to differentiate between left and right Shift keys. You can easily differentiate between left and right when the user depresses that key but, when the user depresses another key while the Shift key is down, you can't easily differentiate between left and right then. If you don't care about left and right then use something like this:
Code:
```Select Case e.KeyData
Case Keys.W
BtnSprite.Top -= 1
Case Keys.Shift Or Keys.W 'Shift+W
BtnSprite.Top -= 5
Case Keys.A
BtnSprite.Left -= 1
Case Keys.Shift Or Keys.A 'Shift+A
BtnSprite.Left -= 5
Case Keys.S
BtnSprite.Top += 1
Case Keys.Shift Or Keys.S 'Shift+S
BtnSprite.Top += 5
Case Keys.D
BtnSprite.Left += 1
Case Keys.Shift Or Keys.D 'Shift+D
BtnSprite.Left += 5
End Select```
If you do care about left and right Shift then post back and we can have a closer look.
