Posted - 28 Oct 2018 : 19:38:21 Hi all,
I created a little script for the automated processing of component attributes. The goal is to loop over all components in a schematic design and check, if there is an attribute with the name "Value". If the value of attribute "Value" has a metric suffix, it should be expanded. For instance, Value=10.2k is expanded to 10200 or 5u is expanded to 0.000005.
Processing of the input data works fine, but I have the problem that the script often aborts with the error
quote:Object doesn't support this property or method: 'Attr.Value'
.
To reproduce this behaviour I cut down the script to a minimum
' vbs
Set Design = ActiveDocument()
if not Design is Nothing then
if Design.IsScm() then
Set Comps = Design.Components()
'Test
for each Comp in Comps
Set CompPart = Comp.Part
Set Attr = CompPart.FindAttribute("Value")
Message(Comp.Name)
if Attr.Value = "" then
Message(Comp.Name & " Value is empty")
end if
next
else
Message("Not a Schematic design")
end if
end if
and run it within a test design with a few components that all have the attribute "Value". It aborts with
quote:Object doesn't support this property or method: 'Attr.Value' Src. Runtime error in Microsoft VBScript Line11: Error:0 Scode:800a01b6
Replacing 'Attr.Value' with 'Attr.Name' in line 11 shows the same behaviour.
It is striking that the minimum version of my script mostly aborts at the second loop run of 'for each Comp in Comps'. But the original script aborts at a more or less undefined time.
Any ideas?

Posted - 30 Oct 2018 : 08:41:24 Hi SeK,
there are 2 problems with your script:
- You try to get the 'Value' attribute from the underlying Part of a Component. If you added or changed this attribute for a Component in your schematics, this is not reflected by the script. - If an attribute does not exist in a Pulsonix item, you always get a runtime error. You have to check if your Attr object exists after you try to get it from the database by inserting a check like 'if not Attr is nothing then'.
So the script would look like
' vbs
Set Design = ActiveDocument()
if not Design is Nothing then
if Design.IsScm() then
Set Comps = Design.Components()
'Test
for each Comp in Comps
'Set CompPart = Comp.Part
Set Attr = Comp.FindAttribute("Value")
Message(Comp.Name)
if Not Attr Is Nothing then
if Attr.Value = "" then
Message(Comp.Name & " Value is empty")
end if
end if
next
else
Message("Not a Schematic design")
end if
end if
