View 15 RepliesI 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.

Ok here we go again, im a complete beginner to coding and have started with visual studio 2008 using the .net/vb libraries, as my first project i went with an emulation application, and it went great:So now i think its time to move onto a little more advanced tech's, so i added in a combo box and i want to change how my code works, and this is where my troubles are.To start of with the combo box, i have it added to my winform and have 3 items on it 'Action' 'RPG' and 'Sim' and i have made 3 .txt files in the projects root folder with the same names. What i want to have happen is when the user selects for instance 'RPG' from the combo box the items displayed in the listbox change to the contents of the rpg.txt file. After searching around for a few hours and no luck i tried this

I am trying to load an Excel 97 single tabbed spreadsheet into a SQL server table using the OleDbDataAdapter function. From all the documentation I have found, the first parameter should be "select * from [sheet1$]". This works fine for me only if the tab in the worksheet is named Sheet1. If I change what's in the [] brackets to the actual tab name, it also works fine.

Im trying to load a price of an item from a prices file (Items). The variable (ItemName) is taken from a listox populated from the file on another form. And (Item) is the structure which i saved the prices information for into (Items).
What im trying to do is take the string from the listbox and change the textbox (txtCurrentPrice) text into the price for the highlighted item, which is also the name of the (txtItem) textbox.
However i cant find a way to reference the Item.(ItemName) to get the correct price from within the file, as ItemName isnt a member of the Items structure Item instance.

ItemName holds the name of one of the variables saved in the structure. So say if ItemName was holding "IridescentRoll" As its string I would be trying to find Item.IridescentRoll, which would show me the price of IridescentRoll which im trying to put into the textbox. and As Item.IridescentRoll = 3.35 it would display 3.35 in the textbox.
As you have probably guessed, the Item.ItemName doesnt work ('ItemName is not a member of...'
Is there any way to write this without having to create a new record for each item? As that would take a while, and im not sure i have the time x.X

I am pretty good with visual basic and visual studio, but the one problem I have is saving... I am currently creating a game, and it has a lot of variables, I want o be able to save all those variables to a text file and then re-open it later. When it is open, i want the variables to have the original value from the text document.
To sum it up: I need variables to be saved in a text file, and then be able to open the text file back and have the variables have the proper values from the text file.
I have been searching around google, and I found ideas, but I have no idea how to use them. Like using XML or saving a table with " TextFile.WriteFromTable" "TextFile.ReadToTable" but I don't exactly get how to use those (the posts weren't too clear)

I have a table in access with 3 columns 1st is called userid and is a primary key and auto number 2nd is first name 3rd is last name. I have a button on my form and when I click it I want it to load the last userid listed in the access table and put in a textbox, say txtuserid. So if the records in the table looked something like
0001 james cold
0002 nick case
0003 john doe
When I click the button I want the last user id in the records to come into the textbox, so in the example that would be 0003, my connection is already set up.
provider4 = "PROVIDER=Microsoft.Jet.OLEDB.4.0;" 'database provider established
dbcustomer = "data Source = ....Booking.mdb"
customerconnection.ConnectionString = provider4 & dbcustomer 'connect the database and the database provider

PS Using Visual Basic 2008 on Vista64.
I am a former IT student and have not used VB in a little while but feel it can come in handy to help me complete some tasks at work.I am trying to write a small program which will open a url + a number for each number entered into the textbox. As an example lets say the website is "www.google.com/id=" and I enter into a textbox 3 values such as "134,325,2112", www.google.com/id=134, www.google.com/id=325 and www.google.com/id=2112 would all open at once.
The purpose of this is at work, we have an employee database and would like to load multiple employees at once (upto 6 at a time) to compare profiles. The issue with doing this manually is we have to fill out the search criteria for each, instead, I would like to load a link with parameters in it already filled out + the employee number we are searching for each number entered into a textbox on a VB form.
I don't know whether it is simple or not because i am new to programming. my requirement is : In my vb.net winform application, the filenames of the files present in "D:Project" willbe displayed in DataGridView1 control.

Then I want to save these files in "C:" with "_de" as suufix to the filename i.e.,sample_de.csv.
