Login Facility Reading In User Info From A Main User File?
Nov 9, 2011I have been trying to solve this for 2 days now, every text book I own and google have been well and truely exhausted and I am still no closer to solving my problems.I have a login facility reading in user info from a main user file. This takes all info into a temp array and then splits usernames into a username file, passwords into a password file and a current score in a score file.
I have the login working fine and everything else in my program works as intended but touching up cosmetic aspects I want to add a Message box after login to say hello and display current score. This works great for the first name in the user file i.e - after login User1 welcome to the game. Your current score is 45 As intended.But the problem arises with any other users, my message comes out as
User2 welcome to the game. Your current score is 55 I do not understand where the random new lines are coming from. I have tried assigning the message as a variable and removing new line using

Reading From File Into A Structured Array?
May 22, 2012I need some input on what I'm doing wrong. What I have so far is an order form program where customers input their information and what they want to buy. Now, what I'm trying to do is take the customer information, store it in an array, write the customer information to a file, and then when I open the order form, it loads the customer information file and automatically fill in a display box on another form with all the customers and the information.I want each customer in a file to be stored on one line. Like so: (Name, address, city, state, zip)
Mike-123 E Dream Rd-Denver-CO-99558
Jane-234 E Code Rd-Seattle-WA-99458
Then when the file is read, to read it, and add each name to a structured array (customers(NumberOfCustomers).Name, customers(NumberOfCustomers).Address, customers(NumberOfCustomers).City, customers(NumberOfCustomers).State, customers(NumberOfCustomers).zip).
After it has all been added to the array, all customers in the file, I want to loop through the array and display each customer on a new line in a listbox, which opens in another form.So far, everything works IF I don't write to a fail. If I store the customers in an array and use a loop to display the customers in the listbox, all is well. However, when writing to a file and trying to read it back into the array is where I've hit a problem. The following code seems to work well, however, it just reads the first line over and over as many times as there are lines in the file, and displays all those using the loop. I just need a way to loop through the lines and store each line into each structured array for each customer, instead of read the first line 12 times over into 12 different places in the array.

Reading Text File Into Array?
Jun 26, 2011So I am trying to learn vb.net and am a beginner. I find alot of online tutorials, but have yet to find one where I can follow what I'm attemping to do, just bits and pieces. I want to keep the code basic until I learn more, and in this case use two - one dimenstion arrays. I built a program to write Employee Names and Wages to a txt file.ie.
Jack Black vbtab 60000
Nick Mole vbtab 45000
and so on
I want to bring back that data and place the name and the and wage each into an array so I can calculate different criteria when I hit a search button. I will not know how many names and wages will be written to txt file. I am having trouble understanding exactly how to do this as all the examples I've found list only one array or the txt file is line by line like.
Jack Black
60000
Nick Mole
45000
Everything else I've found is over myhead so far.Here is my code so far if anyone can let me know where I'm going wrong. I have one error that tells me "property chars is read only". I have no idea what that means, even after reading up on it really...and I'm not sure if the rest of the code I've wrote is 100% anyway I assure you that I've spent more than a few hours trying to solve this myself.

Reading Text From File Into Array?
May 29, 2011specifically reading from a text file, and placing that into an array.
But the problem is, that in each line of the text file, I have at least three different separators.
Sample:
14~8|3~7|16~5|7~4|1~2|3~1|_17
12~12|5~10|2~8|5~7|_0
etc.
[Code]....
So, what I want to do, is read each line of the text file into a separate item into an array, and each item in that array is a record of another array(of terms) and a single(constant).
I've already got SOME code, but I'm pretty sure it's not going to work, and I don't know much about reading from text files and string manipulation in the first place.
