Null Error Setting Property Values

[meck]

I've been fighting with this for 2 days now searching and reading, but to no avail. So someone please help me. All I want to do is set the value of some UPDs in a file that is in that vault. When I run the code below I get...

ArgumentNullException was Unhandled

Value cannot be Null

Parmeter Key Name

This occurs on the vaultExplorer.UpdateFileProperties(oFile, Props) line of code. The array that supplies the values (MetaData) has no Null elements.

Here is the whole thing:

Dim aryPropIDs() AsInteger = {136, 82, 51, 116, 133, 134, 135, 101, 117}

Dim aryPropNames() AsString = {"Rev", "Title", "State", "Initial Release Date", "Dwg Size", "Content", "Component No", "Project", "Unit Type"}

Dim i AsInteger = 0

Dim Props AsNew System.Collections.Generic.Dictionary(OfPropDef, Object)

For i = 0 To 8

'Ignor the file State

If i <> 2 Then

Try

Dim obj AsNewPropDef

                    obj.Id = aryPropIDs(i)

If i = 3 And MetaData(i) <> ""Then

'Create a date object

Dim RelDate AsNewDate

                        RelDate = MetaData(i)

                        obj.DfltVal = RelDate

                        Props.Add(obj, aryPropNames(i))

Else

'Update Properties:

                        obj.DfltVal = MetaData(i)

                        Props.Add(obj, aryPropNames(i))

If i = 1 Then

'Put Title value in Description Also

Dim oDesc AsNewPropDef

                            oDesc.Id = 90

                            oDesc.DfltVal = MetaData(i)

                            Props.Add(oDesc,

"Description")

EndIf

EndIf

Catch

                    ChkInError = ChkInError & vbNewLine &

"Error updating property " & i & ": " & aryPropNames(i)

                    ErrorOccured =

True

                    PropUpdated =

False

EndTry

EndIf

Next

        vaultExplorer.UpdateFileProperties(oFile, Props)

Hi Mike,

I don't see what is wrong looking at the code example. Can you send me a small but buildable example I could use to test this? Also what version of Vault are you running?

Did you see the example in this blog post?

http://adndevblog.typepad.com/manufacturing/2013/07/vault-2014-iexplorerutil-vb-example.html
 
Can you edit that example to work with the file and property in your vault and let me know the results you get? 

Thanks,

Wayne

My appologies Wayne. I am currently on the road and have not had access to the files to give you an example. The files are of 2 types pdf and tif. I am using Vault Pro 2013.
