Substring Size - "Index And Length Must Refer To A Location Within The String. Parameter Name: Length"
Jul 21, 2010If using the following in an if statement I get an error: If trg.Name.Substring(4, 6).ToUpper <> ("ABCDEF") Then I get the error: "Index and length must refer to a location within the string. Parameter name: length"
I assume this is because the string (trg.name) is too small for the 4, 6 substring. What would be the correct method of working around this problem? VB.net Studio 2008.

Getting String.substring(N) Not To Choke When N > String.length
Mar 10, 2010I'm writing some code that takes a report from the mainframe and converts it to a spreadsheet. They can't edit the code on the MF to give me a delimited file, so I'm stuck dealing with it as fixed width. It's working okay now, but I need to get it more stable before I release it for testing. My problem is that in any given line of data, say it could have three columns of numbers, each five chars wide at positions 10, 16, and 22. If on this one particular row, there's no data for the last two cols, it won't be padded with spaces; rather, the length of the string will be only 14. So, I can't just blindly have

C# - Ensure That A String Property Is Of A Particular Length?
Sep 2, 2010I've created some classes that will be used to provide data to stored procedures in my database. The varchar parameters in the stored procs have length specifications (e.g. varchar(6) and I'd like to validate the length of all string properties before passing them on to the stored procedures.
Is there a simple, declarative way to do this?
I have two conceptual ideas so far:

{
[MaxStringLength = 50]

This seems like a lot of work and will really make my currently-simple classes look pretty ugly, but I suppose it will get the job done. It will also take a lot of copying and pasting to get this right.
Checking String If 7 In Length And Contain Any Other Characters

I created this code but when I enter the right string length and characters it always gives me the error for not having the right string length.

View 3 RepliesDetermine The Length Of A String In Pixels?
Jun 29, 2010I am trying to determine the length of a string in pixels.
I created a little test program for myself and placed three labels on it, each with the same font in a different size. I set the width of the label to 1024, the screenwidth. I used the same test text for each label, cutting it off at the last character that shows, so there is not hidden text running off the label to be included in the string width count.
What I have found is that the width of the string is being reported as wider than the label, even though, as I just mentioned, there are no characters running off the edge of the label. So, something's awry. Does anyone know how to get an accurate width?
Here follows the whole test code. You can drop three labels on a form and run it to see what I mean.
Code:
Option Explicit On
Option Strict On
