Either change a parameter or delete and add a parameter on .prt

[ladderman]

Good morning,

My goal:

1.  Have iLogic look for a parameter called "MATERIALQTY" and change it to "MaterialQty". 

2.  Or have iLogic find both versions of the two variations of "materialqty" and make the changes I need for part.

I am running my iLogic on specific parts, not from an asm.  If run just the following;

	OMATQTY = Parameter.Param("MaterialQty")
	OMATQTY.IsKey​ = False
	OMATQTY.ExposedAsProperty = False

The code will do exactly what I am looking for as long as "MaterialQty" exist on the part.  But if "MATERIALQTY" is there instead I receive an error.

I did find code that I thought would help;

    Dim oDoc As Document = ThisDoc.Document
    Dim oCD As ComponentDefinition = oDoc.ComponentDefinition
    'Dim oParam As Parameters = oCD.Parameters
    Dim oParam As UserParameters = oCD.Parameters.UserParameters
    
    For Each oPara As Parameter In oParam
        Dim oName As String = oPara.Name
		
	If UCase(Left(oName, 11)) = "MATERIALQTY" Then oPara.Delete

But I found that this code will delete both "MATERIALQTY" and "MaterialQty" parameters.

Is there a way to either find "MATERIALQTY" and change it to "MaterialQty" in the parameters so I can change .iskey and .exposedasproperty to false???  Or have iLogic look for both versions and then change either of them to iskey and .exposedasproperty to false???

Try this

Dim oDoc As PartDocument = ThisDoc.Document
Dim oCD As ComponentDefinition = oDoc.ComponentDefinition
Dim oParams As UserParameters = oCD.Parameters.UserParameters
Dim oParam As UserParameter

For Each oParam In oParams
	If oParam.Name.IndexOf("MATERIALQTY", 0, StringComparison.InvariantCultureIgnoreCase) > -1
		Try
			oParam.Name = "MaterialQTY"
			oParam.IsKey = False
			oParam.ExposedAsProperty = False
		Catch
			oParam.Delete
		End Try
	End If
Next

Thank you very much for that!  I would have never figured this code out.

Can you breakdown how this line is working by chance..?

If oParam.Name.IndexOf("MATERIALQTY", 0, StringComparison.InvariantCultureIgnoreCase) > -1

What does the IndexOf and ",0," do exactly???

It was the first result on Stack Overflow

This is how I understand it...

.indexof("materialqty") returns a numerical value. It is useful for finding the n'th member of a string or a multi-value parameter in inventor.  And it returns -1 if it doesn't exist. ", 0," is either setting the start value or the number  of members in the string.

Looking back at the post you could also do a .contains() method to compare the string to a value., but this way  might have just been longer.
