Make The User To Be Able To Select A State From A Combo Box?
Feb 8, 2009
I'm setting up a program where I would like the user to be able to select a state from a combo box. I can not figure out how to allow to select the abbreviation from the drop down list and also allow them to type a letter and it will select the state from the state or just allow them to type the full abbreviation that would match what is already in the list. It is supposed to be in the drop down list style. I would also like to confirm that the user has chosen a state before allowing them to click a submit button but I'm not sure how to go about confirming it.
Private Sub FrmMain_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
' Inserts state abbreviations in combo box
cboState.SelectedItem = " "
cboState.Items.Add(" ")
[code].....

I have a VB2005 winforms application that will loads city data from my database table. This is to ensure that the user enters the correct city spelling, in order to receive an accurate quote. Currently, there are about 150K cities that are being loaded to the dropdown listbox on page load. It takes about 30-40 seconds for that page to load. My initial thought was to allow the user to select the state first. Then load the city values. But the user has the option of going back and requesting a quote for a different city / state.

Create an application that allows the user to select or enter into a combo box the number of days a person will work, and calculates the total amount of pay she will receive over that period of time. Salary is one penny the first day, two pennies the second day, four pennies the third say, and continuing to double each day.
The combo box must list the following items: 30, 180, 365, and 1000. Must be the default drop down box. Use a validating event procedure on the combo box.
The program should go through a loop once for each day, doubling the number of pennies with each iteration of the loop. You will need a running totl of the number of pennies that you add to with each iteration. To calculate the total amount of pay, multiply the total number of pennies by .01 and show the result in currency format.

I am using visual basic in VS 2008 and trying to learn how to assign a value to a word in a combo box using case select, this is my first attempt at programing and i just can't work out what to do next. So far i have two combo boxes a label and a button, i want the word, first to = 11, second = 9, third =7, fourth = 5. All it is doing at the moment is adding the list index value and displaying that total in the label. I want it to display for eg: if (first=11) and (second=9) are selected a total of 20 in the label,and so on for what ever combination is selected.

I am a noob and I am trying to make a simple resistance calculator for practice. I use text boxes to let the user input the current and voltage, and then a combo box for the units and then a list box to display the results. For some reason no matter which units I select it doesn't convert at all. For example 1/2 will always show up as 0.5 in the list box no matter which units are selected from the combo box. Here is my code.....I know that there is more cases but I only put one to see if it
Public Class Form1
Dim unitsA As String
Dim unitsV As String

I am using VB 2008 Express to connect to an Access 2007 database. I have a combo box that is populated by the database. When I used the Access report VBA, I used the AfterUpdate() event to calculate a sum and place the results in a text box. I need to know how to do the same operation in VB 2008 Express using the SelectedIndexChanged event of the combo box.
The combo box is called "cboYearMonth" and is populated by my database, this is working correctly.
The text box that I want the calculated results to appear in is called "ExactPagesTextbox"
I have a query in Access called "JobTypeExact_Query" that contains all the pages that I need. What I need to do is calculate the total number of "Pages" limited to the YEARMONTH selected in the combo box. YEARMONTH is a value in every record in this query.

I am writing an app that uses a combo box to list file types for a user to select from. Because a complete list of all options is both impossible and wildly unwieldy, I am only providing about 10 common extensions. I want the user to be able to type in their own file extension if the one they need is not listed. the first item in the combo box is empty by default, but during testing when i type something in their to use as my selection, i get the exception "Object reference not set to an instance of an object." pointed at extensionComboBox.SelectedItem.ToString
