I 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.
Is 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 End Class

i seem to have a problem when i try to select a ComboBox item which is a drop down list. The ComboBox contains a list of various items where the user can select from a list, the type of query he/she would like to perform on an Access Database. Two of the items in the Drop Down List are "Employee Sales Between Specified Weeks" and the other item is "Employee Sales Between Specified Months" (without quotation). Now in my VB code, i have a really long If/ElseIf Statement which includes all the options the user can select. Additionally, if the user has selected a week query, he/she must select a From Week, a To Week and a Year (for example week 3 to week 5 year 2009). From Week is another combobox (1-53 weeks) and To Week is also another ComboBox (1-53).When the user selects a month query, he/she should select a From Month from a ComboBox (1-12) and a To Month from another ComboBox (1-12) and the year from the same Combobox (e.g 2009).
My combobox dropdownlist contains 60 to 65 items. So i want to show 5 items in the dropdownlist of my combobox and add a vertical scroll bar in it so that the user can scroll it and see the items.

What I would like to do is bind a combobox to my own object which is as follows:
Public Class Categories Public Sub New(ByVal myConn As SqlConnection) Dim myConnection As SqlConnection = myConn myConnection.Open()

I have a small requirement and that is: There are two combo boxes on a form and for populating the employee names and roles. I am populating the combo boxes as follows: I have created a class called "DbConnect" and in that there are 02 functions as:
Public Function getEmployees() As DataTable Dim employeeDS As New DataSet Dim employeeDA As New SqlDataAdapter("prc_emp_list", conn) employeeDA.Fill(employeeDS, "employees")
[code].....
The data is getting populated into the combo boxes correctly and my requirement is that when I select and employee from the first combo, his corresponding role should get selected in the second combo.

In a Windows Form application (VB.NET) I have a combo box and under certain conditions, when the user opens the DropDown list, I want to display a warning message.All of this works well: In the DropDown event, I check the conditions and if required I display the warning message.The problem is that when the user clicks on Yes on the warning message, I move to another tab on the main form and the drop down list still shows even though I've moved away from the tab containing the combo box.I've searched quite a bit and tried to set DroppedDown to False, call OnDropDownClosed, etc but nothing worked.It seems that when I try to close the drop down list from within the DropDown event, it doesn't work.

I have created a combo box in my project which takes a certain amount of numbers from a file. This Combo drops down the list of the numbers each of represents something. That something I want to be displayed in a tooltip when the mouse hovers on the combo box. Until now everything has gone fine.

Is there some one to assist me on that?
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.
I've found some unexpected behaviour in my ComboBox, which I'm hoping someone can help me with. If focus is lost by pressing the Return key on a form which has AcceptButton set, then after handling the Validating event and cancelling the validation,the ComboBox will not drop down any more. When you click on the drop-down arrow, the list drops down momentarilly then goes away again To reproduce this, create a new VB.NET Windows Forms application. Drop a Combo Box and a Button onto the default form, then add the following code:[code]....
Run this application, click on the Combo Box, enter some random text (e.g. "asdf"), then press Return. After this, click on the drop-down arrow on the Combo Box.I'm using Visual Basic 2010 Express on Windows 7 Home Premium.
