Combo Box Not Keeping Value On Tab Out
Dec 9, 2009
How can i get the combo box to keep the value that was partialy keyed in and completed with auto complete.Pressing enter doesn't select the value so when you tab out it keeps the entered auto completed value. The only way to keep the auto complete value is to click on the combo box with the mouse and then tab out of it. I would like some how of being able to tab out of the combo box and it keep the auto completed value that the user has entered so as to save time entering data so no mouse clicks are needed and the data grid view can be tabbed through and all data entered from keyboard.

Anyway I am writing a program to allow the user to enter:
-size of pizza which is a combo box (CmbSize)
-type (thin crust or standard) of pizza which is a combo box (CmbType)
-pizza choice (spicy chicken, maryland etc) using a checked listed box (ChkdListChoice)
The problem I have that will probably be simple to a lot of you who are using this language frequently is that I simply want keep a running subtotal of the users choice. So for example the user chooses 8" Spicy Chicken - 3.50, then they press the BtnAddToOrder button to output it to the Textbox (TxtPizzaChoi). When the user adds the next pizza I simply want the previous pizza price to be added to this one giving a new subtotal. I have not made the price change if the user changes the size to 12" spicy chicken, the price is still 3.50, simply because I think this could make it more difficult to me and I don't have lots of time to work on this. My declarations are not all in use and i may not need them by the way.
Heres the code:
Public Class PizzaChoices
Dim price As Decimal
Dim topping As Decimal

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

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?

I have developed a very simple application that disables system keyboard commands (ctrl+alt+del, alt+tab, etc), hides the taskbar, hides the desktop, etc.Upon entering a password the user can 'unlock' these options.This is being used with a restaurant POS system so no accidents can happen. However there seems to be one minor issue:In a separate software package (the POS software), at specific times, any application that is running (my locking application) will get focus and end up on top of the POS software.I want my locking software to remain underneath all running applications. Anyway to keep my locking application from gaining focus? I was thinking of maybe adding some line of code to send my locking application into the background whenever it gets focus..

I have been working on a VB app to edit an excel document. I want to keep my excel workbook in scope for the whole app.
For example here is how my program looks now
private sub
open workbook
end sub
private sub
reference workbook
end sub
I want a way to just call my workbook at the top and have all of my subs recognize it. I guess like a global variable or something.

I've been trying to find the answer to keeping an application from allowing "scaling" of controls and forms to the user's settings. I have set the autoscalemode to "none" on one form but it doesn't seem to work. I'm using Visual Studio 2008 Visual Basic. My users are on using either XP or Windows 7. I think we are all using Framework 3.5 but not really sure.
I knew this problem would eventually become an issue but ... Now the problem has become an issue. I have a user that has dual monitors and has the text setting on medium. Now the label controls overlap the input text fields.

I have two combo boxes, and four buttons. When the user clicks "Add" on the first combo box, it adds a new item to the combo box with "New" and then lets the user rename that item to something else. That "new" item has to have an array of "answers" that go along with that item in the list. What I'm having trouble figuring out is assigning "answers" to the second combobox for each item in the first combobox and changing the second combobox when selecting an item in the first combobox.
EXAMPLE:
Item 1 - Combobox1
- Item 1 - Combobox2
- Item 2 - Combobox2

I have an application that connects to an SQL Server, sometimes we have a networkinterruption of min 10secs during the openconnection , I get a General Network Error when I try to carry out any procedure that communicates with the database afterthe interruption. Even when the connection is closed and reopened, I still get General Network Error. The only way to get the application to function again is to close the Application and reopen it, is there any way I can keep the connection alive?

I have been on a hiatus from VB for some time. I was coding in C++ and C# for quite some years and on my venture back to VB, decided to put my trusty VB 6.0 on the shelf and try out the new 'rave' VB.NET. I'd first like to say, I can't imagine how different it is from older versions. I'm using Visual Basic 2005 and I find myself sometimes pulling my hair out over things that were common practice before, yet have been totally revamped. But I'm getting by, barely, but getting by.
My problem is this: I am writing an application that loads the Title field of a DataGrid (after being loaded from a DataTable of course) into a ListBox then sorts them. The problem is, upon sorting, I lose the original index value that pertains to that entry in the DataGrid. In other words, if the first ListBox item is selected, it contains the index value of the first entry in the DataGrid, which stores the rest of the data to fill the labels and controls on the form. I have a semi-workaround for this by iterating through the DataGrid and comparing the Title field to the text of the selected item in the ListBox, but the downside to this is that you could never have the same named item or you would only get data for the last item entered. My question is... Is there a way to somehow retain or store the original index values of a ListBox before sorting? If so, this would make my code a lot smoother and allow for multiple entries of the same name in the Title field of my database.
P.S. If someone could go through how to access items from the DataTable itself, I could get rid of the DataGrid altogether, as I don't need it other than to access the DB data. I couldn't figure out how to get at it while it is in the DataTable, so I loaded it into a DataGrid control and made it invisinel.

I am trying to create a quiz application in Visual Basic 2008. I need to be able to store a score value when the player gets a correct answer. When the value is stored a new question set appears. Once the score is calculated I want to be able to show this is in a new form so the value needs to be passed from one form to the other. I'm not entirely sure how to do this but I believe it will incorporate a module.

Suppose i want to draw semi-random ellipses on my form.Is there any way i can check if they get clicked at a later stage?Is there any way of storing the location of individual ellipses and then comparing the mouse-click to my list of locations to see if one was clicked?
I can imagine how it could be done with squares or rectangles, but i dont know how to approach it with ellipses.
Im sure this has been asked before, but i've spent a good while searching around for something i can use and came up emptyhanded.

What happens here is when I click on anyone of the radio buttons the text box score sets the value to either 0,1,2,3,4 but when I go the next case it goes back to 0 instead of keeping the value. I tried many different techniques while going about this none seem to work.

I have a form with 8 combo boxes and would like to disble certain combo boxes, depending on what was selected in another combo box. The reason is so the user will not have a blank return on a query. The first form I created like this worked great, no issues. This form only allows one combo box (Number_of_Lightheads) to disable any others. Below is the code I have for this Form. why the other combo boxes will not disable the ones that are called out in the code?
