iLogic: Using a shared variable value to suppress constraints

[ian_solomon]

I am trying to set the suppression state of a constraint based on a shared variable value, and it just does not seem to work. I have renamed the constraint to "Cap", and the shared variable is called "CHSS".

The three values of this variable are: "NG250_WS_RH", "NG250_WS_LH", and "NG250_WS_NIL".

This is the code I am using:

'Set Cap constraint
If SharedVariable("CHSS") = ("NG250_WS_RH") Then
	Constraint.IsActive("Cap")= True
ElseIf SharedVariable("CHSS") = ("NG250_WS_LH") Then 
	Constraint.IsActive("Cap") = True
ElseIf SharedVariable("CHSS") = ("NG250_WS_NIL") Then 
	Constraint.IsActive("Cap") = False	
End If

 I have also tried this:

'Set Cap constraint
If SharedVariable("CHSS") = "NG250_WS_RH" Then
	Constraint.IsActive("Cap")= True
ElseIf SharedVariable("CHSS") = "NG250_WS_LH" Then 
	Constraint.IsActive("Cap") = True
ElseIf SharedVariable("CHSS") = "NG250_WS_NIL" Then 
	Constraint.IsActive("Cap") = False	
End If

What do I have wrong?

what if you remove the () from NG250... in you if then statement

Hi ian.solomon ,

I did a quick test and it seemed to work as written.

Here is a quick example you can use to test. This example sets the shared variable with an listbox, and then suppress the constraint depending upon the what is selected. 

I hope this helps.
Best of luck to you in all of your Inventor pursuits,

Dim oCHSS_options = New String(){"NG250_WS_RH", "NG250_WS_LH","NG250_WS_NIL" }

SharedVariable("CHSS") = _
InputListBox("Prompt", oCHSS_options, SharedVariable("CHSS"), _
"iLogic", "CHSS Options")


'Set Cap constraint
If SharedVariable("CHSS") = ("NG250_WS_RH") Then
	Constraint.IsActive("Cap")= True
ElseIf SharedVariable("CHSS") = ("NG250_WS_LH") Then 
	Constraint.IsActive("Cap") = True
ElseIf SharedVariable("CHSS") = ("NG250_WS_NIL") Then 
	Constraint.IsActive("Cap") = False	
End If

I'm gonna seem like a dufus, but it was working. I was just calling up the wrong shared variable... doh!!

Thanks for the help anyway.
