I'm still trying do read some data from a serial port device. After a lot of "surfin' the web", I finally found some documentation. It says that "All info must be xor with 0xDF before seperated".
View 1 RepliesI'm brand new to visual basic and I've been given an exercise to extract data from a text file. I can get the lines of data to read in and can get the names out using the following code. How can I extract the department i.e. sales and finance also using the mid and instr functions? I also need to be able to list list the people by department using a dropdown combo box.

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.

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.

I need to extract a html table and show the data in comma separated format. Below is a similar html table from which I need to parse data.
View 4 RepliesI 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?
View 6 RepliesWhen I look at a file on my hard disk, e.g. test.csv, when I look at the Properties of the file, it is officially known as, "Microsoft Office Excel Comma Separated Values File", and file types of .pdf are listed as "Adobe Acrobat Document", etc. etc. All of this information can be seen in Windows Explorer too when my folders are displayed by Details. How do you get at this "type of file" information with .NET?
View 2 RepliesI 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
(It is not Join or split - I know about this, .net has new built in function to create CSV format)
Check Jacob G Answer below for what i was looking for let me know your thoughts on it compared to join ;)

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.

Not sure if I am using the correct term, but it's not child/parent since they aren't nested objects. In my application I've got a User, UserUserGroup, and UserGroup objects which are pretty standard, UserUserGroup is a linking object with corresponding IDs. I am using Linq-to-SQL so unforunately it doesn't used nested objects, but it still knows the relation.

What my problem is that, how can I load this .txt file to a datagrid and arrange it in a 3 columns. That .txt file is auto generated that's why i cannot do anything about the textfile.
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.")
[Code]....
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!
