I'm creating a vb.net winforms application that will take in user given strings, parse them, and print out labels with variable information. The given string will be used in all the labels, but the variable part of the string will change with each label.
My question is: is it better to parse the strings one time, then store those values in arrays, or to parse the string each time a label is printed? Which will perform better? Which is better practice? What is the proper way to test something like this?

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.

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.

View 6 Repliesi am having problems trying to code this application, here is the assignment: Amusing Toys, Inc. wants to store the description and the number of items on hand of its toys in a sequential access file named stock.txt. The company's sales manager wants an application that lets the user enter the descriptions and the inventory in tow list boxes. Then he also wants to retrieve the file so it is possible display the inventory of a toy whose description he selects from a list box. The List box with the description should appear as soon as the application is loaded. Create an application which: initially adds the information to list boxes so the information can be checked, places the data in one or two arrays, saves the information for retrieval later, contains test data for at least 10 items.here is what i have so far i cant get the information to line up correctly in the list box from the text file and also i have no idea on how to get the quantity to show up after i get it to line up correctly i think i need an array.

I have a very long string. I need to parse this string so I can get information out of it. I know what each segment starts with and ends with. The length of the information will vary. I don't know what the easiest way of parsing this string.

So i will want to get everything from ST to AK1then AK1 to NM1 and so on and so on.
I have a string array (strValues()) that holds a large quantity of character data. I need to parse out characters that follow "*PN" and end with "*". I then need to store this data in a datatable so that I can loop through it afterwards and pull out the unique records to be added to an existing dataset. I've been trying to use basic "IndexOf" to get started but it tells me "Overload resolution failed because no accessible 'IndexOf' accepts this number of arguments". Is there a way to accomplish what I'm trying to do?Sample data: MS50*CF3224205*PNineed/thisdata*SD07JAN10*ED21JAN10

View 2 RepliesAfter countless hours of searching I have been unable to get this code to work. If anyone can provide we with an alternative. I know the easiest way is to use the Split() function but im trying to do an alternative method by identifying the spaces within the string and splitting them up.
I tried the search function, but to no avail.
Attached is the code.

I'm trying to find a way to parse a string which looks like this:
1,394,7,0,0,0,0,0,,0,0,63,85,0,,0,0/2,595,59,8,0,0,0,0,0,,,0,0,,0,8,6,0/3,696,0,0,0,0,,,0,0,,84,0,0/#
So that it only reads the first two digits, then delete everything after that till it reads a "/", read the first two digits and delete everything up to the "/" again.This would result in this:
1,394
2,595
3,696
I don't know how to remove every character after the last of the first two digits up to the first / it reads, can anyone help me with that?How can I parse this code easily?
I need to parse a string that consists of fields in quotes, separated by commas. Using Split would work fine, but sometimes one of the fields has a comma in it. ie. "My Company, Inc","USA","12.50","125000"I'm just looking to get the fields into elements in an array. Can someone suggest a way to handle the embedded commas that are sometimes present?
