[2008] Default Value For A Combo Box?
Feb 13, 2009
I'm in a VB Class, so we're not doing anything doing anything too complex, but I'm writing a program using Combo Boxes as a drop down boxes.When I run the program, they come up blank, and I'm trying to set the property of the Combo Box to show up with "(None)" instead of just being blank, but I can't find the control to set the property for that. I have all my items in the collection, and I'm wondering if there is a control character that will denote it as default in the collection set similar to when typing & before a letter will denote it as an "Alt-Activated" control.

I got a combobox which is filled with values from datasource. By default the first value is chosen which is fine but I need to display "Choose country" as the default combobox text. The user then can choose from the drop down list.

i wanted to link options selected from Comb box A (general) to specific options in combo box B (specific). I want to pick a word in Combo box A that has specific words/phrases in Combo Box B show. But not all the words to show in the combo box B if they aren't associated with the Word picked in Combo Box A. Ex.When "Soda" is picked in A, only "Coke, Sprite, Fanta" should be visible in combo box b, not everything else.This is the code i used to make the boxes, but i don't know how to link them.
Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' fills the combo boxes with values
Me.xGeneralComboBox.Items.Add("Soda")
Me.xGeneralComboBox.Items.Add("Juice")

How to use a databound combo box to display one field in the drop down, and another as the combo box text on roll up? Using VS 2005... For example, I have a datatable that has 2 fields. One called "ShortDesc" and one called "LongDesc". I want to be able to see the "LongDesc" column values in the drop down on the combo box. When I make a selection, I want the text in the combo box to read the corresponding "ShortDesc" value.

Combo box 2 is filled based on a selection made in combo box 1 and a listview is populated based on the selection made in combo box 2.When the LostFocus event completes in combo box 1, it hits the LostFocus event in Combo Box 2 but it shouldn't. How do I prevent this from happening or if I can't prevent it, how do I work around it? The following is the code used.
Private Sub cboCategory_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles cboCategory.LostFocus

Within my application we store objects i.e images,word docs, etc etc. These are stored in a listview and when the user double clicks the item it launches the default application assigned to the file type i.e a bmp will launch paint, doc will launch word etc etc.
Everything works great in all versions of windows except the new Windows 7 where i am getting this error message:
Im guessing this is something to do with permissions etc, but can anybody shed more light on this and where to look?

I need to print the contents of 3 textboxs to default printer. what examples I have found dont seem to work. I was trying the documentprint1 component as i thought it would be easy but cant figure out how to tell it what to print the second part is to print a variable (string) to the printer as well.no need for user to select just straight to default printer with its default settings

I have a combobox which contains a sample of names selected from a table.Currently the default name displayed in the box is the 1st name found in the table. What I would like to do is display the name of the person who is doing the selection as the default. The name is stored in a public variable 'PubName' and I do not want the user to be able to type into the combobox themselves.Is this possible?

I've got some code like the following. I want it so that when I chose an item in 'select 1' it changes the in the second combo box but I'm not sure of the best way to go about it. Does it have to be AJax or can it be done with just Javascript?

How do you make the autocomplete feature on combo box in VB behave in the same way as one in VBA?
the VBA properties are as follows:
MatchStyle = fmMatchEntryComplete
MatchRequired = True
The VB properties are quite different and i havent got a satisfactory combination. I need it to suggest items from the list as i type but insist on a match with the list. However on VB forms, unlike VBA forms it doesnt show the suggestion in the combo box itself, but in a box beneath.

Below is the code to create a single Editable ComboBox column in a DataGridView on a form. I believe I have follwed the instructions to allow the user to input new values other than those in the list, however if you create a new project and add a button and a DataGridView control onto the form, then copy and paste this code and run the program, you will find that you cannot type any character in the edit box other then characters that exist in the list and only 1 character will be displayed at a time. I have set the Autocomplete value to 'False' and setting it to 'True' at least allows me to type more than 1 character but still not any strings that don't exist in the list.You can even remark out or not use the entire Call Validating sub routine to see the issue of not being able to type in the cell.
