Events firing willy nilly
 

[Excel2000]
I have a form with a number of comboboxes and listboxes on it.
Some of these controls change the values of other controls, causing their
events to trigger. I want to stop this in some cases. Has anyone got any
suggestions?

For example, cmbName is changed, and this changes everything else including
cmbType.
But cmbType has a macro that I only want to run when cmbType is manually
changed, but not when its value is changed by another event.

Is it possible to achieve this?

TIA
Darren

You would probably need to set a global flag to determine how the control is
being changed. It could get pretty cumbersome with multiple controls. Here's
some untested pseudocode:

Dim fSwitch As Boolean

Sub cmbName_Change()
fSwitch = True
'make changes to cmbType
fSwitch = False
End Sub

Sub cmbType_Change()
If fSwitch = True Then Exit Sub
'your code here
End Sub

You get the idea.

Darren,

I don't know of any "disable control events" parameter.
One way is to have a global Boolean variable which tells other events
whether something's already going on.

eg.

Private i As Long
Private blnExecuting As Boolean

Private Sub TextBox1_Change()
If blnExecuting Then Exit Sub
blnExecuting = True
i = i + 1
TextBox2.Text = Left(TextBox1.Text, 1) & i
blnExecuting = False
End Sub

Private Sub TextBox2_Change()
If blnExecuting Then Exit Sub
blnExecuting = True
i = i + 1
TextBox1.Text = Left(TextBox2.Text, 1) & i
blnExecuting = False
End Sub

Update: thanks again, Vasant and Rob. I've got the global variable method
working - whew!
