.net - Parsing Fixed Length File With Regex?

May 8, 2012

I'm parsing fixed length file with .NET 3.5 and Regex. This file is from bank. In customer name sometimes there is one characters from this set &,(),[],',"". These are characters, so far I've encountered. There can be anything else. Because of this my regex is failing. My regex is [A-Za-z0-9s-.,'""""(){}[]]{35}. Is there any wild card I can use for special chars rather than specifying individually. I also tried . but didn't work.

How To Read Through A Fixed-Length File

Dec 7, 2005

I've a text file which has some data written. Records have Starting character as "#2" and Ending character as "#3" in ASCII respectively and the file includes series of records, but not written as Line by Line. The difficulty I'm having is, to how to transfer those data's into a database. The File comes a 7mb file and looping character by character then noting down the Record Starting Character and Record ending Character, and finally substring them is not feasible as it take more time and makes the computer slower. I would like to know is there any easy way to transfer them?

Breaking Up A Fixed Length Flat File Into Fields?

Jul 12, 2011

so i have a file that i need to read in vb.net. Each line is 32 chars long and each line consists of multiple fields. Meaning from char 1 to 9 it idicates ID then char 10 indicates an identifier,11-14 indicates a value field. I've looked at Readblock and it's not the tool for the job. Is there a way to break up each line into its respective fields other than just reading the whole line and breaking it up as a string?

Are Arrays Really Fixed Length In ASP.NET 2.0

Jul 14, 2010

If I dim an array to say, 5 elements, should it not fail if I go to add a 6th? I thought this used to require a redim. In .NET 2.0, I have a character array of length = 3. When I populate it from the db, one record had 4 characters in it and it successfully added all 4 characters to the array?

Generating A Unique ID Of Fixed Length

Jun 17, 2010

I don't know if I can do this here...but here goes. I want to generate a unique ID of fixed length The trouble is, the code example I found on the web is in C# (or C maybe) which I know nothing about. I tried a web-based C# to VB.net converter but the result doesn't work so its hard to understand what's going on (especially since I have not worked with bytes either this makes it more difficult).

Calling Older VB Dll (possibly Fixed Length String)

Jan 21, 2010

Got a dll from a supplier that I need to call. His declaration is Declaration with Microsoft Visual Basic: [code]Now, the Sting * 20 is clearly not VB.NET, and sure enough it crashes when run - "Attempt to read or write in protected memory" and that leads me to think that there is something with that string definition - or possibly the I_Ref definition which hasn't been defined as fixed length.I've tried <VBFixedString(20)> when defining O_Err, but I have a feeling that it might not be enough when the function declaration is like that (not specifically fixed length). I cannot figure out how to specify this correctly.As a small hmmmm, the above is pasted directly from the suppliers documentation, but that't will never work, as there is a "," missing after I_Range as long... Clearly not something he has pasted from a working program.

Parsing Out The Contents Within Brackets Using Regex?

Dec 20, 2011

I'm sure this is simple and I'll probably be embarrassed to have this question in my profile but I can't seem to get this Regex correct.

I'm tring to extract just the digits from the last group of the following string:

Properties[1].Securitymeasures[14].AdditionalSecurityType

so I want to have a regex that will return 14

The Regex I have come up with is:

[(d)+]

However - the match is returning "[14]" - including the brackets and I do not understand why. I have surrounded the d with parenthesis which should mean that this is the data I want to capture.

Regex - Parsing Excel Reference With Regular Expression?

a(0)="Sheet1"
a(1)="14"
a(2)="1"

I'm sure it can be done easily with a regular expression, but I just can't get the hang of it.

Create A Fixed-length Unique String From Another Unique Numerical Value That Is Too Long?

Feb 13, 2012

I am using VB .Net to access the eBay API and store all completed orders in a database. This database is then fed into a proprietary shipping system, which can not handle an order number larger than 20 characters. eBay returns an order number like so 230407279314-680141236013 which is too long. The order number is always 12 numbers a hyphen and 12 more numbers. What I need to do, is turn this (the result can be alpha numerical) into a shorter, unique order key to store in my database alongside the true orderId (so that this can be referenced by the shipping software instead of the actual order number). The reason for the 20 character limit is the barcode algorithm used. Is there any way to achieve this in VB .Net 2010? This number can be anything unique, so long as it does not exist already (even a good uniqueid function would work, but I would have to query the database to make sure it isn't taken)

Regex Replace All Characters In Variable Length String?

Oct 6, 2010

Using VB or C#, I am getting a string of variable length from the database. This information is sensitive information that only certain users will be able to see.I have two cases that will use the same logic (I think).scenario 1: replace all characters with xscenario 2: replace all characters with x except the last 4 characters (assume length > 4 - this check is being done).I thought that this would be easiest using Regex.Replace(input, pattern, replacestring). As opposed to a lot of string handling with substrings and forcing a length of 'x's.

Regex - Does The Local Part Of An Email Address Have A Minimum Length Requirement

I noticed that in order for the e-mail address to validate, I need to put in at least 3 characters before the @ symbol. Is this a requirement? What if I just want to have an e-mail address with 1 or 2 characters before the @ symbol?
