Three very simple questions.

[jejacks0n]

ok, three very simple questions.

How can I check to see if a button is being held down?
I'm trying to increment a number when a button is pressed. How can I continue to increment that number if a button is pressed and held?

I'm also looking for some examples of pseudo-3d code. I understand this isn't assembly, but there has to be some examples out there. Vector examples or something.

Is it possible to change a PictureBox image?

2. Don't know
3. Yes....

Set Picture1.Picture = LoadPicture("C:\myfile.jpg")

Can you use an UpDown control? Try this on a sample project and see if it will work for you. Its in the common controls.

Option Explicit
Dim iNum As Integer

Private Sub Form_Load()
iNum = 10
Text1.Text = iNum
End Sub

Private Sub UpDown1_DownClick()
iNum = iNum - 1
Text1.Text = iNum
End Sub

Private Sub UpDown1_UpClick()
iNum = iNum + 1
Text1.Text = iNum
End Sub

You want it to imcrement while its held down, don't you? Start a project, put 2 Command buttons, cmdUp and cmdDown. Put 2 timers tmr Up and tmrDown and Text box Text1. Paste in this code and see if it does what you want.

Dim iNum As Integer

Private Sub cmdUp_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
tmrUp.Enabled = True
End Sub

Private Sub cmdUp_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)
tmrUp.Enabled = False
End Sub

Private Sub Form_Load()
iNum = 10
Text1.Text = iNum
tmrUp.Interval = 100
tmrDown.Interval = 100
tmrUp.Enabled = False
tmrDown.Enabled = False
End Sub

Private Sub tmrDown_Timer()
iNum = iNum - 1
Text1.Text = iNum
End Sub

Private Sub tmrUp_Timer()
iNum = iNum + 1
Text1.Text = iNum
End Sub

Private Sub cmdDown_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)
tmrDown.Enabled = False
End Sub

Private Sub cmdDown_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
tmrDown.Enabled = True
End Sub

I think this will do what you want.
