I am new to vb.net and I am using visual studio 2010. I have two comboboxes on a form, each combobox is set to DropDownList so that a list of items can show in the combobox, but no text is allowed to be entered.
For combobox A, if user chooses item 1, the list of combobox B should be updated accordingly. I think this is quite common on a lot of applications. But I do not know to implement it. I even do not know the keyword to search for the relevant property or event handler.

I'm making a combobox on a form. I want the combobox to have a list of choices from a table in a db. The two columns are a String and a Date. I want the date column to only show the year. I'm hoping I have the code right as it is above, but I'm not positive I've done the whole date thing right.
1, Mulroney, Brian, 4000, 3, 259.2500, 300.00, 1265.7500, 75, 20002, Schreiber, KarlHeinz,8000, 1, 2227.0000, 2400.00, 10873.0000, 300, 160003, Clark, Glen, 4500, 0,12.3750, 337.50, 1525.1250, 75, 22504, Harper, Steven G., 20000, 3, 0, 0, 0, 0, 0so what I want to do is I wanna insert the four last names in the combobox when reading the file and displaythe data regarding each name in the listbox. so when you click on each last name in the ombobox, you can display the corresponding info for it in the list box..so my problem is1)I can only read one of the lines in the file(only for one last name). and therefore only one last name appears in the combobox.how do I read and insert the other three lines at the same time?

I tried the code below but unfortunately, all i get is a combobox with U,s,e,r,s, as each line in the items collection and not the filenames of the relevant files.
the DirGetPath("Users") Function below returns my default document and application paths and appends "Users" to the end as the relevant files are stored in that Folder.
All I get is a combo box with the items as U, s,e,r,s (i.e. Users spelled out).
I tried all of the following as alternative methods too:
System.IO.Path.GetExtension()
System.IO.Path.GetFileName()
System.IO.Path.GetFileNameWithoutExtension()

this code needs to be modified to be able to enable the user to select a file in which to store grades. The application should allow the user to write any number of grades into that file and it should write one grade per line. Then it has to be modified to allow the user to specify the location and name of the file containing grades. The application should read the grades from the file, then display the total of grades and the class average.I have it writing to the file fine, but I can't get it to read from a file.Imports System.IO ' using classes from this namespace
Public Class EnhancedClassAverage
Dim fileWriter As StreamWriter ' writes data to a text file
Dim FileName As String ' name of file to save data

Downloading the string would use too much, is there a way i can read it straight from the WebPage without having to download it? It's a a two row table.
I need to compare a TextBox entry to something in the List -first row- and then pull some data from the second row.
I have Strings writen to a file.
But i then want VB to read the file, and input ALL the strings in that file into a ListBox.
I have been having some problems with my Visual Basic. In trying to figure that out, un-installing, and reinstalling, running virus scans, etc, I have lost a lot of my time to get this assignment done. I would just keep messing around with it and try to be further along, but I must move on.
We have a form application with 3 tab pages. The first tab page takes input for first name, last name, phone, birth month, and birth year in textboxes. This info is to be written to a file. The next tab page has a read button that then displays the data into a list box. The next tab page has a text box to take input for a birth month and then searches through the file and lists any file that matches that birth month.
The whole thing then needs to be serialized and deserialized.I will post what I have so far. My first question is what do I need to do to get it to read into the listbox? I have tried multiple things. None work. After the issues I had with my visual basic, I don't know if for sure it is me, (most likely), or the software.For the display, we are supposed to use an overloaded ToString method in another class. Do I have to use an array?
private void EnterFriendBtn_Click(object sender, EventArgs e)
{
friend.FName = Console.ReadLine();
friend.LName = Console.ReadLine();

View 1 RepliesIs using Public Property the best way to achieve the following.From a drop down combobox, a list of options are available. Each option in the combobox has a number of public properties that need to be associated with it.When a option is selected, the user will then have two buttons that each call a different sub, the appropriate options are passed to the sub.Each option will always have the same properties required to be passed.So I'm looking at something like this.
Public Class Parameters
Public Property server As String
Public Property replica As String
Public Propery path As String

View 3 RepliesI have created a drop-down list box that holds 8 numbers representing a month span (3, 6, 9, 12, 15, 18, 21, 25 months). In order to prevent users from typing just anything into the text box above the combo box, I changed it to a drop-down listbox. The other requirement that I was hoping to implement was for the user to be able to type a number, after which the selection would jump to the appropriate item (i.e. the user types in '1', and the selection jumps to 12). This partially works. It will jump to 12, for example, but immediately after the user types the '1', the Selected Index event changes. The user cannot scroll down or up after typing in a number.

How can I create images on ComboBox list
View 3 RepliesI want to populate a Combo Box with a list of names and from that have the contact information (address, phone, email, ect..) populate a series of textboxes. The list is roughly 20 names, but it could grow to a hundred or more. Since the contact information changes periodically, I would like a very easy way to maintain it (Excel or Access).
Update: I am just trying to understand whether I should use Linq (have to learn it) or is there some other way this should be done.
