ahhhh .... the different ways of treating nothingness!  Who would of thought the concept of nothing was this difficult.  I only brought up Null time values because Sean asked specifically for a vbscript and  the time functions will fail if a null date is encountered....  ... View more

perhaps if you want a formatted string with leading zeros ... use the show codeblock option.  In any event the above vbscript code (and mine as well) will fail if NULL Date values are found and your will have to handle your logic for missing dates! CodeBlock: strDate = CDate([BirthDate]) strDay = DatePart("d", strDate) strMonth = DatePart("m", strDate) strYear = DatePart("yyyy", strDate) If strDay < 10 Then    strDay = "0" & strDay End If If strMonth < 10 Then    strMonth = "0" & strMonth End If FormattedDate = strYear & "/" & strMonth & "/" & strDay Bottom Window: FormattedDate  sample output  "2017/03/05" ...

I was looking through some old vb code today and ran across this VB6 code project from ESRI it exposes how to create a style file in ArcGIS version 8.   If I am not mistaken, not much has changed with the styles since?   Maybe you will find this useful.... ... View more

Like you I thought this turned into a case where None simply does not work as expected ...  I do run across that quite often when I deal with data from multiple sources and platforms .... ...

... sorry did not convert to Python'ese   '-'.join(filter(bool,(field1,""))) --- and no it is not recommended only if the trustworthy None does not work (field contains unprintable artifact values).  ... View more

One of my last resort tests when nothing else seems to work is equating null to blank myfield1 = [Field1]+"" if myfield1.strip() = "" then     'This could be null'  ..... "Python Nulls Strike back!" ... View more

Dan_Patterson‌ is correct, shapefiles do not support alias names. However some folks have gotten around this issue namely in storing the alias within the host mxd file using the properties dialog or by incorporating "Metadata" which does have a field for alias and use programic means of reading meta files and returning the field's alias.  Either method is not pretty!  ...

I see no reason why it would not be doable?  You are able to get users name / roles  and if you have a foreign key within the photo table a  filterable relationship could be established or handled by code.   This looked promising ... How To: Get the current user name and roles using a server object extension  ...

I do not believe there is a straight forward way of doing it... I use GeoWizards and renode and buffering to apply  number of lane changes to the split point....  In your case, quickly looking at your problem... I would suggest to do as Dan Indicated and split the rail lines at each station.  Hopefully each railstation has an unique ID... if not create one....  I would then buffer each rail station so that it overlaps both sides of each rail.  Then use the intersection query and transfer the pertinent node/(Rail Stations) data to the segmented rail line so each rail segment (line) would have 2 nodes(stations) identified a begin station and end station ...  from there it becomes a database join query to analyze . ...
