Comma Separated Data File, Saved As A Text File?
May 30, 2011I 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 RepliesInput A Text File Of Figures Into A 2-dimensional Array?

Input Data To Windows Pgm From Text File?
Sep 29, 2009I need to get data from a text or excel file and input it into a windows program that I do not have source code for and cannot get it.What I am trying to do is get sales order data from one of our customers in a file and then read the file and input the order information into our sales order system by actually stepping through the order entry process so all the checks for item #'s, zip codes, etc that are already in the sales order entry software are utilized, basically so that data files integrity is maintained.
I am very green when it comes to programming, can anyone tell me if this can be done using vb.net or should I look into using another programming language.

Loading A Text File (comma Separated) Into DGV?
Feb 3, 2012i have code for loading a text file (comma separated) into my DGV:

sb.AppendLine("Failed to load text file, see error messages below.")

Load Up A Text File Which Has Employee Info Separated With Commas?
Apr 13, 2009I'm new to Comma Delimited values. What I'm trying to do is load up a text file which has employee info separated with commas
like 1/1/09, John Smith, (555) 555-5555, 101 S 1st Street and has numerous rows of info like this
so what I want it to do is just write this info to 4 different textboxes

then another text box for names and so on.. Right now I just have it all being written to one text box.
I'm not sure how to separate all the information accordingly.

Changing Data In Text File Or Array?
Dec 15, 2009I have a csv text file, shown below that I want to edit based on user inputs. When the user wants to change the current price of a stock, they enter the stock name, and the new price. When the button is clicked, VB needs to find the appropriate stock, and then change the current price.The data needs to be pulled from the text file into a temporary file, changed, then the temp file needs to be renamed to the original file name and the original file deleted.This is the only part of the program I can not figure out. I have put my program code here as well. The click event that I need this to work on is: Private Sub btnUpdateStock_Click --- I have been playing with code in that section, so that's why there si abunch of crazey code there.

View 1 RepliesFile Input (String) To Array
Sep 30, 2008I am trying to write a program that reads values from a datafile and makes the data available in an array for further use in the program. The data consist of a description and then a value (COM_PORT=COM1, for example). My idea is to put the data in an array so that I can just search the array for COM_PORT and I will get COM1 back. Is that a good approach of handling it this way? What methods would I use to put the data (I use FileSystem.ReadAllText, the data is in a string) into an array? Would the split method work?

Read Individual Lines Of A CSV File Into A String Array, To Then Be Selectively Displayed Via Combobox? Input?
Apr 2, 2010I've got myself a CSV file with the following contents:
1,The Compact,1.8GHz,1024MB,160GB,440
2,The Medium,2.4GHz,1024MB,180GB,500
3,The Workhorse,2.4GHz,2048MB,220GB,650
It's a list of computer systems, basically, that the user can purchase.I need to read this file, line-by-line, into an array. Let's call this array csvline().The first line of the text file would stored in csvline(0). Line two would be stored in csvline(1). And so on. (I've started with zero because that's where VB starts its arrays). A drop-down list would then enable the user to select 1, 2 or 3 (or however many lines/systems are stored in the file). Upon selecting a number - say, 1 - csvline(0) would be displayed inside a textbox (textbox1, let's say). If 2 was selected, csvline(1) would be displayed, and so on.
It's not the formatting I need help with, though; that's the easy part. I just need someone to help teach me how to read a CSV file line-by-line, putting each line into a string array - csvlines(count) - then increment count by one so that the next line is read into another slot.So far, I've been able to paste the numbers of each system into an combobox:
Using csvfileparser As New Microsoft.VisualBasic.FileIO.TextFieldParser _
("F:folderprogramnameprogramnameinDebugsystems.csv")
Dim csvalue As String()[code]......
But this only selects individual values. I need to figure out how selecting one of these numbers in the combobox can trigger textbox1 to be appended with just that line (I can handle the formatting, using the string.format stuff). If I try to do this using csvalue = csvtranslator.ReadLine , I get the following error message:
"Error 1 Value of type 'String' cannot be converted to '1-dimensional array of String'."
If I then put it as an array, ie: csvalue() = csvtranslator.ReadLine , I then get a different error message:"Error 1 Number of indices is less than the number of dimensions of the indexed array."
