[Resolved] Key Text Box

Hmmm, i'm making a program that will take screen shots.

I want to assign a text box to show what key(s) to press to take the screen shot. I also want it to be able to be changed by the user.

For example, when the text box has focus and the user is holding down Ctrl+S then the text box will say Ctrl+S. If if the user if holding down Shift+Ctrl+D then the text box will say that.

I'm going to be using a system wide keyboard hook to watch for the keypresses (to raise the screen shot event).

If anyone knows how to do this, or a better way to do this please reply here. All my effors have failed so far, such as getting the ASCII from the text box.

have u try a "keydown"....?

Yes, i have tried it. But the numbers are wierd:

Ctrl+Z = KeyCode=90, Shift=2
Z+Ctrl = KeyCode=17, Shift=2
Ctrl+Shift = KeyCode=16, Shift=3
Shift+Ctrl = KeyCode=17, Shift=3
Ctrl+Shift+Z = KeyCode=90, Shift=3
Shift+Ctrl+Z = KeyCode=90, Shift=3

How does one make sense of that? They are the results i got.

try this vb code

Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
Dim vCtrlDown
Ctrldown = (Shift And vbCtrlMask) > 0

'When u press Ctrl button
If Ctrldown Then
Label1.Caption = "CTRL+" & Chr(KeyCode)
End If
End Sub

VB Code:

Dim Key_ As String
 
Key_ = Chr(KeyCode)
 
If KeyCode = 112 Then Key_ = "F1"
If KeyCode = 113 Then Key_ = "F2"
If KeyCode = 114 Then Key_ = "F3"
If KeyCode = 115 Then Key_ = "F4"
If KeyCode = 116 Then Key_ = "F5"
If KeyCode = 117 Then Key_ = "F6"
If KeyCode = 118 Then Key_ = "F7"
If KeyCode = 119 Then Key_ = "F8"
If KeyCode = 120 Then Key_ = "F9"
If KeyCode = 121 Then Key_ = "F10"
 
If KeyCode >= 112 Then If KeyCode <= 121 Then GoTo F_Key
 
If KeyCode <= 40 Then Exit Sub
If Shift = 0 Then Exit Sub
 
F_Key:
 
If Shift = 1 Then Text1.Text = "Shift+" & Key_
If Shift = 2 Then Text1.Text = "Ctrl+" & Key_
If Shift = 3 Then Text1.Text = "Ctrl+Shift+" & Key_
If Shift = 4 Then Text1.Text = "Alt+" & Key_
If Shift = 5 Then Text1.Text = "Alt+Shift+" & Key_
If Shift = 6 Then Text1.Text = "Ctrl+Alt+" & Key_
If Shift = 7 Then Text1.Text = "Ctrl+Alt+Shift+" & Key_

That is working fine as far as i can tell. Thanks for your code, it allowed me to see how this actually works. If you have a better way please post it!

maybe it's better if u know vb constant value for keycode, like:

if keycode = vbKeyF1 then .......'when you press F1 button
if keycode = vbKeyF2 then .......'when you press F2 button
if keycode = vbKeyEscape then .......'when you press ESC button
if keycode = vbKeySpace then......'when you press SPACE BAR button

and so on....

Use the help file - look for keycode constants.

The shift, ctrl and alt keys work like this:

vbShiftMask = 1
VbCtrlMask = 2
VbAltMask = 4

So if you hold alt and shift keys, the Shift value would be 4 + 1 = 5.

Yep, thanks for that!
