Comma Separated Data File, Saved As A Text File?

May 30, 2011

I decided on a comma separated data file, saved as a text file. This is for data that will not change. After loading the data from the text file; then throughout the lifetime of the program the data can change. The data can then be saved back to a different binary file. The idea is to have a save state system going.Does anyone have a suggestion or is opposed to the idea. Is there a simpler way to organize something like this?

Loading A Text File (comma Separated) Into DGV?

Feb 3, 2012

i have code for loading a text file (comma separated) into my DGV:

If Not DataGridView1.LoadTextFile(TextBox1.Text, ErrorList) Then
Dim sb As New System.Text.StringBuilder
sb.AppendLine("Failed to load text file, see error messages below.")


I'm wondering...is it possible to run this code if the user was to drag and drop the text file onto the datagridview, rather than having to navigate via buttons etc...it'd make it a much nicer method!

VS 2008 - Creating Comma Separated File

May 22, 2012

This is my first 'serious' VB2008 project. Attempting to write a comma separated file. vis:


Is there a better method for outputing the data, rather than having to concatinate all the elements into a string and then writing it? In the 'good old VB6' days a Print statement followed by each value and a separator would do the trick. I can't seem to find the appropriate override for the WriteLine method.

VS 2008 - Combobox And Comma Separated Textfile Value Loading In To A Textbox

Jun 11, 2010

I am trying to write a vb2008 program that allows a user to select an airport from a combobox and then once the value has been selected it searches a comma separated text file once it has found the airport selected ( always the first column in the file) in the file it populates 8 other textboxes with the row data from the file. The idea is to select the airport and then it calls up the radio frequencies associated with the airport.I assume you have to call the data into an array and the search thorough the array until the combobox.selectedvalue = the value in the array, but i am unsure how to do this Ideally I would like to be able to the user to add data to the file thats why I used a combox, but I am having trouble trying to get the boxes to populate so first things first.

C# - Comma Separated String Built In .NET?

I used a built in function to create comma separated string using List easily.(It is not split and join but new function) I'm not able to recollect or find it. If some one knows about it and uses it please post a link to that. Framework - .net 2.0

.net - Extract A Comma Separated Number From A String

Jan 24, 2012

I'm trying to write two regex's - you'll need to tell me if they're even possible. Both are based on VB.net syntax.

Regex 1:
The string I'm testing against -
Size on disk: 25,754,900,936 bytes

It has a handful of leading spaces, but the text is ALWAYS the same. I'm trying to extract out just the number (25,754,900,936).

I've tried a handful of regex's, but I can't get everything on one line. The commas are messing me up and returning multiple matches (For example, d+W+ gives me four matches, one for each set of numbers separated by commas.)

The best I've done is [0-9/,]* but that gives me 25 empty matches and one match (On match 19) of the number. I need this to match on match 1.
