In my program i have a listbox populated with data from a sequential text file. [code] Mary, Murphy, 16, 893782, Douglas etc.From here the user selects the person they wish to see displayed in the datagrid with all all other relevant details from the text file displaying. Problem is I cannot figure out how to refer to the selected person and then get it displaying on its own in the datagrid. [code]

I am trying to create a program for a voters poll, where when a caller calls in, I can enter their vote for one of the four choices in the listbox and it will be automatically added to the vote count. I got that much to work, I need to save the vote to a sequential text file, when a vote is saved. I know I am close but it is just not quite working. I only need help getting the info to save to the sequential text file. I have also included a jpeg of what the form looks like.

I know that Deleting a specific line in a sequential text file is impossible but instead copy the needed lines and not copying the unneeded ones to an output file .. killing the old one and renaming the new one with the same.. I can't make this step...
That is my record file

Input #1, CustomerName, CustomerHomeAddress, CustomerBussAddress, CustomerTel1, CustomerMob1, CustomerID, DateRent, CarRegPin

I made a form that when you put your CustomerID in Text3 Box.. it access the records and make some calculations. now.. The customer will return the car.. Then his data should be deleted.. I want to know how to make that when I enter the CustomerID and press on the Command button .. It copies the other lines to a new output folder and doesn't copy these ... So it appears to be deleted using this way..
What I am trying to do is connect a sequential text file up to a list view.

View 1 Repliesi need help with stream writer, i can get it read lines and stuff like that but now i need Streamwriter to write to a colour.txt file (already populated with data) and insert a line that isn't already in the file, into alph order eg combobox reads and displays list from txt file.
their is a colour thats isn't in the text file, so i would like it to take the colour from the combobox that was typed in by the user and place it into the colour.txt file in alphabetical order (these are car colours so their are 100's and 1000's per manufacturer, its not as basic as i want red blue black lol) i was able to find loads of data about streamreader but not so much about stream writer
I need to write data from a list box to an lsv text file. I can do that if I rea an entire line at a time and write it out, but the data in the listbox are columnated.For example:Cey,Ron 50 75 75 66.67would be an entire line from the listbox. It was entered into the listbox by reading an lsv text file and using format string to set up column info, but I don't know how to read it back out by column, only by entire line.

I'm studying VB 2010 at uni and struggling with this assignment, I'm stressing now with one week to go before its time to hand it in and still not knowing how to do it (even though i've read the whole textbook!)
I have copied the instructions and the files I have been given.
1 List all of the data from Teams.txt in a Listbox. Include suitable headings.
2 List all of the data from Results.txt in the Listbox (use the same Listbox as in 1 above). Include suitable headings. Note that you cannot assume that the file contains only results for the first 3 weeks of the season. Your program should be able to process a results file with more or fewer results.
3 List all of the data from Results.txt in the Listbox. However, in this case the actual team names should be output (your program will need to get this data from Teams.txt. The data should be formatted so that it is aligned correctly. Include suitable headings.

I have built a system for a shipping company to use that takes user input from various sources (Textboxes, RadioButtons etc) and displays it in listboxes below. What I need to do is create individual shipping numbers for each of the consignments added based on certain criteria, that being:When adding a consignment, the system should generate the consignment number automatically in the format XY12-xAB, where x is a number that increases by 1 for each consignment, AB is the Shipment Type (EA, SA or SF) and XY12 is the Office ID.
So far, I have this:

I've been ttrying to code an app that will act like the VB intellisense, without the added properties. In short, when I type (in a multiline RichTextBox), the letter t I would like the populated listbox show at that point (because "Then" is a word in the listbox) and if I click "Then" in the listbox have it "autocomplete" the word and display it in the color blue.
lstKeyWords.Location = rtb1.GetPositionFromCharIndex(rtb1.Selectionstart + 10)
lstKeyWords is the ListBox and rtb1 is the RichTextBox - This was the only way I could get the ListBox to show in the "almost" correct position?

My teacher as asked me to allow a user to input three pieces of information about a DVD (the ID, the title and the running time) and for the program to add that data to a sequential file. My textbook fails to explain it and I am at a loss as to where my book from last semester is located at the moment.
1. What is a sequential file?
2. How do I display information from it into a messge box?
So basically i have the need to only process a command when the text box is populated, if the textbox is not populated i want it to throw a simple msgbox

I am working on a program in Visual Basic that incorporates using a sequential access file for a ballot type program. Each type the user clicks the save vote button, the amount of votes gets stored.
What I am trying to do is in my access file is to display the number of votes as an actual number. The way my program is written right now, the name of the candidate appears as many times as the vote was saved.
for example, if perez was voted for 4 times, in the access file perez is displayed on 4 different lines. How do I display the actual number of how many time they were voted for. I'm thinking using a counter variable, but not really sure how to really implement it in. this is what i have so far.
