Basic VB or Python help needed

[SandraHanslip]

I have 2 tasks for which I cannot find the right syntax and really would like some help

First I have a column with strings and I need to calculate how many characters are in each string and put that number in my field_len column. Sounds simple - and sad to say, I did it once but cannot pull it out of my hat again.:cool:
(There are two of these counts and when I ran another calculation on a separate field, the numbers switched ie: in a field where most values were 14 they are now 10 and the field where the values should and used to be mostly 10, they are now 14.) So I just want to run the character counts again.

Second, I have a column (string) which I need to take the 1st 10 characters and copy over to another field - actually, did this once as well but it left over 1000 blank - for no discernible reason. Copy and pasting these one by one is gonna take forever.

Any help or directions are greatly appreciated. I can usually find my way through Python or VB but I just can't get there on this.

1. Right click on field_len column > Field Calculator > len(!String Field!)


2. Right click on the other column > Field Calculator > !String Field![0:10]

Thank you for your response.
I tried this and the process failed and the error I get is 99999
I manually corrected the Account Numbers so they are 10 characters if available, now just need to get the counts.

I have attached a word doc with screen captures of errors and abbreviated table I am trying to run calculations.
Acctnum_Len should return a maximum of 10 and acctID_len should return a maximum of 14  (These fields are to give a count of how many characters in Account Identifier and Account Number)

Thanks again,
Sandra

In the Field Calculator dialog select Python parser at the top instead of VB and try again.

The only other thing I would check is the length and type of the acctID_len and Acctnum_Len fields.
If they are TEXT fields make sure the field length is not less than the number of characters it will hold.

Yes, thank you again. I have already checked all of those and I just can't get the Acctnum_Len field calculator to count the characters in the account number field. I did it before for both fields and it was not difficult but I just can't get there again!

It's really strange that they have reversed themselves. Maybe I'll just switch the names of the *_len fields;)
