grabbing user parameters from a referenced document

[swordmaster]

trying to write a external ilogic rule that will run in a idw

I want it to access the User parameters of the referenced document. Then i want to take the user parameter and write it to a string variable.

I have something that works up to a point, this is a shortened version of the code

Dim oDrawingDoc = ThisApplication.ActiveDocument

Dim oUserParams As UserParameters

For Each oRefDoc In oDrawingDoc.AllReferencedDocuments

oUserParams =oRefDoc.ComponentDefinition.Parameters.UserParameters

MessageBox.Show(oUserParams.Count & "user parameters in referenced document", "Title")

this works the message box returns the correct number of user parameters in the referenced document.

However i cannot seem to grab the value of one of the user parameters and use it.

I have tried various things like

Dim test As Parameter

test = oUserParams.Item("myuserparameter")

or (this is closer to what i want)

Dim test As String

test = oUserParams.Item("myuserparameter")

this errors out and i do not know why!

I guess i will also have to worry about units since myuserparameter is in inches  and the variable i am assigning it to is a string,

Any thoughts, guidance or nudges in the correct direction would be much appreciated

thanks in advance

Try this:

Dim test As String
test = oUserParams.Item("myuserparameter").value

Mike, thanks for that.

Your suggestion worked great. Only thing i had to do was take care of the units. Since the API workes in centimetres and my parameter is in inches

Dim test As String

test = oUserParams.Item("myuserparameter").Value/2.54

There might be a more "elegant" way of converting the units, but this will do me fine

Hi,

Have a look at the UnitsOfMeasure object: http://adndevblog.typepad.com/manufacturing/2012/07/unitsofmeasure-object-and-example.html

It also has a ConvertUnits() function.

Cheers,
