sir, i have no idea how the code will look, but i want it to assign a value after reading from a text file and then store it for further use even if the text file is not there, but without using any external storage like registry, disk, ram. It should store the value in itself and do like this:-

I am working on a media player, and I would like to setup a local playlist feature. I am using a single ListBox and its "Display-" and "Value-Member" properties.

I'm using the SaveFileDialog to save listbox info into a text file. The files save fine, but when you go to save the file, if you hit the cancel button, it will overwrite the previous file you saved, because it's name was the same and it seems to save the previous file as the new name for your next file. Is there any way to catch if the user clicks cancel, and then exiting the sub if they did?

Within each customer profile there could be any number of databases for just that customer. and with in each database there is a system to keep track of different things.
Main Database = List of different Customers

Customer database key systems = list of key generated and if the have used that number or not. (Along with other info)

I am doing an assignment for my intermediate programming class. It is due tonight at 730. Anyways, I am almost finished, but I have run into a snag. I have this "bank application" and we are storing the info in a text file. However, whenever there is a deposit or withdrawal, the "accounts.txt" file is to be updated. All of the new account info is being written to a "Temp.txt" file and eventually will be renamed to the new "Accounts.txt" file. The problem I'm having is that it isn't writing non-updated account info to the temp file and I don't know how to make it do that while keeping the accounts in order and not rewriting the same account info more than once.

I pretty much understood how to write text to a file, but I cannot grasp how to READ the information. After I read the information, I would like to add each seperate line to a ListBox. Each line in the text file is a file path for a music file, as the file I wish to read information from is a "custom extension" playlist file. I know what to do after I get the file path, but I do not know how to get the file path from the playlist.

The reason this jumps around is that this comes from a file that is edited by other modders when they create a ship for a game that I'm modding.My program is designed to allow the user to visually see a representation of how strong and well equiped a ship is and change the values of each line with a slider bar.I have all the slider bar and progress bar code worked out.
I just need a way to reliably pull these lines no matter where they are from the ship file chosen by the user so that the program can edit them without disturbing the rest of the text in the file.
I am writing a program that lets someone click on a picture to vote for their favorite pet. The part I am stuck at is: when the application is opened and closed it needs to remember how many votes there were.

name, type, votes

View 9 RepliesI'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
like txtdate would just have all the dates of employees listed in rows or multilines
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.
