I have a program where you have three entries, CD name, artist, price and it goes into a listbox and .txt file when closing. I have to have a message box if you enter the same CD name. I have a code to open the .txt file and compare strings but I need to change it to compare only the CD name and not all three entries. Is there a way to do my string compare against my listbox without opening the .txt file?? The program loads the listbox from the .txt file when opening. Private Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click' adds CD information to the list box
' declare variables
Dim strName As String
Dim strArtist As String
Dim strPrice As String

I am working on getting a multiple values from a single column displayed in a single textbox or label. I know I should be able to find the information I need online, but I am coming up empty. I am using Visual Studio 2010 with SQL Server 2005. For example, I want to pull all the email addresses, that have a value, from a table and display them together. The output I am looking for is like this:

Hi, I'm working on a program that reads text entered into a textbox and creates a list of items by separating entries by commas. Everything is working fine, except, because I am using an array to store the items in the list, I have a limited number of entries. This is only a problem because, as it is written currently, each comma counts as an individual entry. Therefore, users can enter ",,," for example, and it would use up 3 places in the array.
I'm looking for a way to check to make sure there is text after the comma before adding an entry. I've attempted to use the .substring command to check the character after, which works until it gets to the last character. Because there is no character after that, it will give an error.
Here is my code for extra clarity:
Public Class frmMain
Dim intCounter As Integer 'Stores the # of commas in the string
Dim Messages(49) As MessageProperties

I have a tool connected to access database. It retrieves the database based on certain input conditions from 4 textboxes, 1 list box. The data from database comes to a datagridview. I have to enter certain values in a particular column in datagridview and continue with my calculations.At this stage I wan to save my file with the data I have entered so far. Is there a way i can save this data into another file (for example say " SAMPLE"), so that when I open the SAMPLE file from my tool it should display all the values I have saved in the respective controls.

I have code that works to place two items in listbox into two textboxes when selected (multiple select extended).
Private Sub lstOutput_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstOutput.SelectedIndexChanged
Dim i As Integer = lstOutput.SelectedIndex
[code]....
I need also to be able to modify the data in the textboxes and replace the lines in the listbox. The reverse code doesn't work properly, it only replaces the first selected item. The "lstOutput.Items(i + 1)" appears not to lead to the second selected item.
Dim i As Integer = lstOutput.SelectedIndex
lstOutput.SelectedItem = lstOutput.Items(i + 1)
lstOutput.Items(i) = txtName.Text
lstOutput.Items(i + 1) = txtPhone.Text
I have scoured the web for ways to manipulate the selected index/indices, with no success.

I've imported data from a text file using Streamreader and populated a listbox with this in 3 columns. I now need to
a) get a total value from the 'Hours Worked' column (sum) and
b) put in a calculation to populate an extra column for each entry (Gross Pay) where values are not imported but entered as a result of a calculation.
My current code is as follows:
Private Sub btnRefresh_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRefresh.Click

I just starting coding in VB.net about two weeks ago so I'm still a begging and I learn best by seeing working code and then adapting it to my situation. That being said, I need help displaying table entries in a listbox. I've successfully created a database in my test application, added it to my Data Sources and used a drag / drop method to add Datagrid View & Details (labels & textboxes) to my application for testing purposes. Now I want to try and display table entries in a listbox.
Example Database:Table: Contact
- ContactID (autonumber) [primary key]
- FirstName (text 50 limit[code]....
Also is there any benefit or down side to creating a database in MS Access, create the relationships & tables, then attaching that database to my application or is it better to create the database in the application like I did in the example above by using the Add New - Service-Based Database option?

My program is half a formulator, and half ordering system. Where I get stuck is the ordering system part. In one screen I have 5 check boxes that you can check for which products you want to order. The products you checked then get sent to another screen and put into a list box with a quantity variable that starts at 1 attached to it. Now, if you check the same product again, another time through the program, as of now, quantity accumulates to 2, which is good, that's what I want. My problem is I want quantity to keep accumulating, right now it accumulates to 2, then on a third pass through the program,it duplicates the entry, so now in the list box has the original product and quantity of 2, and another entry that has the product with quantity of 2. 't quite understand how they work. Here's the code:
Option Explicit On
Option Strict On

I have a program with two forms, one that handles the applications controls, and the other with the functions that open a file (csv), open a database, and query the database. The controls on the first form are a list box, three labels (to display parsed csv information), and three buttons (clear database, load database from csv, and load listbox).
The clear database and load database buttons (events) seem to function correctly.On the other hand, the load list box event doesn't function 100% the way I'd want. [And, I can't test the selected index event yet]
The code for the load list box event is:
Code:
Dim db As New DBUpdt 'second form
b.openConnection("weather.mdb") 'open database connection
db.query("SELECT * FROM stations") 'query database
Do While db.moreRecords

You see, in my new VB application, I have a form with a TextBox and a ListBox, and I need to make it so that, whenever some text is written in the TextBox, a SELECT operation must be performed in a table belonging to an SQL database, in order to return the elements of a particular column that are LIKE the text I just wrote in my TextBox. The results of this SELECT operation must then be written inside the ListBox.In other words, whenever I have some text inside my TextBox1, I have to do:
SELECT Description FROM Elements WHERE Description LIKE TextBox1.Text (this must be done whenever the text changes)And the results of this operation must be displayed in the ListBox on the side.

Just what the title says. I have a listbox with varied entries, all in one format:name, email, phone, age
When an entry is selected, and when a certain button is clicked, I require the entry to be removed from the listbox and the four categories from the entry must each go into their assigned textboxes.

Instead of a UDT containing a string variant ie If .view="Left" then
Can it be changed to a list of defined entries in the UDT If .view.Left then
I could define the subentities as boolean but each time I change one I would have to change the others
.view.Left = True
.view.Right=False
.view.Top=False
It would just make coding a bit faster. I don't know if it's possible but I've been surprised in the past when I didn't think something was possible.

i have an access 2007 database in wich i have a table named abc_PersonalLog, wich also has three columns: Id (auto number), StarDate (text) and LogEntry (Memo). It is a Diary application. So, when the user makes a log entry, the StarDate column receives a string formed of concatenated year, month and day, i.e. if date is 20th march 2012, the string will be 120320, and the Log entry column, the text entered by user in a textbox.My problem is that, somehow, i have to retrieve that data, when the user will want to read log entries he made. I managed to assign the text property of a label to the LogEntry text for a given date.But, if the user makes multiple entries in a single day, the table will have several rows containing the same string in the StarDate field, but different text in the LogEntry fields. How can i display ALL the LogEntry texts for all the rows containing the same StarDate value? Here is my code so far:

I am trying to take a database with multiple entries of 11 digit numbers and run a check sum algorithm that adds the 12th digit to the 11 digits as an output.The algorithm is as follows:
Add sum of odd digits starting with first digit, then multiply by 3.
Add sum of even digits, then add to result of odd digits multiplied by 3.
Take result and divide by 10. The remainder is the check sum which needs to be added to the end of the original 11 digits.

I am to make a program that lets the user save certain data values with a delimiter(":") to a text file(done) Example of data entries [code]Then i am to load those values to a listbox , i was able to do that as well and i include the delimiter when i load the values.Now i am supposed to let the user enter any month/year value for date(mm/yyyy) such as 06/2010 and if any of the entries match the search string then either the program selects those values in the listbox or a popup msgbox is used to show the entries. How the result is displayed is a little irrelevant, but how do i search and atleast select the matching entries in the listbox ? and not just the first instance but all instances of the search string.

I want to make a utility that allows the user to edit Jump List entries. There is some kind of tie between the raw junplist filenamess and the app, for instance:
Excel = cdf30b95c55fd785
Word = adecfb853d77462a
Those were found by trial and error and there are a few more on the net.
For MS Word the file is "C:UsersusernameAppDataRoamingMicrosoftWindowsRecentAutomaticDestinationsadecfb853d77462a.automaticDestinations-ms"
What I'm wondering is if anyone knows how to determine what filenames go with what program. Deciphering the files will be another issue for sure

I have data entries in my database that have a common field. For example:
account_id type user_id
1 new 1
2 old 3
3 new 1
4 old 1
I am using a query like this(mysql): SELECT account_id, type, user_id FROM table WHERE user_id = 1
This is just all theoretical. The problem that I am having with this is it is only returning the first result in this case account_id 1. How can I get it to find all the results with the user_id 1 because in the way I am thinking that it is failing is that it is finding only the first result and then ending?
