Selecting An Item From Database To Add To A ListBox
Dec 15, 2011
Our project is to make some simplified POS software, in our case, for a restaurant. The form I am currently working on is where you pick food items and add them to a listbox which will essentially be the order form. I made a database in Access that has food-item info and linked it to the VB project.url...My combobox narrows down the food items according to what category is selected, i.e. "Lunch".Now.. is there any way I can select an item from my database records (right box) and add them to an empty listbox that I'll save to a txt file. The database box is called "FoodItemsDataGridView" but maybe I don't even refer to that, I have no idea..
I want to have a listbox on the left and on the right a textbox and when i select an item in the listbox i want to read a text file or database and display the value related to it and then have the ability to amend the content.
I have a listbox with all items related to a person written in one line, e.g. Name, Gender, Phone #, Address, Email (all separated by a ControlChars.Tab).. How do I choose each individual item alone, e.g. Name, from a line to put it in a separate line in a file.This isn't working.. Can you tell me what code to use?
Dim outputFile As New System.IO.StreamWriter("Info.txt")For i = 0 To lstAllInfo.Items.Count - 1outputFile. WriteLine(lstAllInfo.Text.Substring(0, lstAllInfo.Text.Substring (" ")))Next outputFile. Close()
I'd like to select a node (item) in the TreeView control to get its path information as a string. I'm finding it's not like selecting an item in a listbox.
The List Box has three candidates and a record Button. Every time the record button is hit I need it to add those button clicks for each candidate that is selected in the List Box. My code keeps counting all the clicks no matter which candidate I am selecting in the List Box. How can I differentiate between each selected item in the List Box.
Private Sub exitButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles exitButton.Click Me.Close() End Sub
i'm doing a desktop application using VS2005 with MSSQL 2005. i have a problem with the where clause in the update statement while selecting the listbox item. this is the code for the listbox in load page:
[Code]....
and this is my update query in the delete button event handler: mySQL = "update Appointment set recordStatus = 'deleted'" how do i put in the where clause in when i have 4 columns in the listbox? so can i do this with listbox or have to do with datagridview?
Ok, so I`ve been studying a bit of VB lately.. bought a few books and read lot`s of articles and seen hours of instructional videos, and I slightly start to get the hang of a few things.. :) I`ve recently started a fun little project, but I seem to lack a bit of knowledge to reach my goal. I`ll first try to describe my project:
I've been working on a little sidebar project for fun about a casino. It may have a couple of card games like, war and eventually 5 card draw. I haven't begun any card programming yet because I'm on a screen that shows players.
I want my listbox.items is come from a database. I use the listbox.datasource in that problem but when I run the program this is happen to my listbox..
This is the code of form_load vb.net Try Dim con As New OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:UsersMaynielDocumentsVisual Studio 2010ProjectsSampleSystemUserAccount.mdb") Dim command As New OleDb.OleDbCommand("Select Username from tblUserAccount", con) Dim table As New DataTable [Code] .....
How can I done when the user click an item to my first listbox it will open another listbox that category of the first listbox item..
How can i remove an array item by selecting an item from listobx and press remove/delete button?for an example, if i want remove index 2 from listbox, so the array should remove index 2 item and move the item of index 3 to index 2 and so on.
In my application I have a listbox and SelectionMode should be MultiSimple because users need to see which items they selected. In another tab we have another listbox this one should show all the selection users had done in first tab. Private Sub
I trying to make a code to Delete and Update Access 2007 database after remove a selected item from a listbox in VB 2008. [using "Remove" button that i create] pervious i already make a button to View data from database and Remove from listbox. but i don't know how to delete and update in database.
The code i using now:
CODE:
In the database, i have ID,Name and Age (simple database)
My problem is i have two comboboxes, cmbFamily and cmbModel, I have values in cmbFamily: A320, A330 etc And i have a database that has all the available models for these aircraft types, i have got some help on a query so i can fill up cmbModel with all the models of aircraft available, but i only want to display the models related to the family that is selected in the cmbFamily combobox.
The query i have so far is
Query = New OleDb.OleDbCommand("Select Model From Availability", AccessConn)
'AccessConn is my database connection string I would like to have something that views the text in cmbFamily and then looks for all related model entries in the dataset.
Say I have a listbox lb, which I initialize using:
lb.DataSource = wordList \wordList is a list of strings lb.DataBind()
The listbox is initialized perfectly, and everything that should appear there does.
However, now I select one of items in the listbox with my mouse (coloring it dark blue, in case anyone wondered what I meant in "select"), and perform the following test:
When my application starts, it scans the computers registry for COM ports and adds them in the combo box. The combo box first index is just a blank, and the second is COM1, COM2,...COMn. What I want to do is by default, I want my program to select the first COM port in the combo box, so in this case, COM1.
I know I have to use the PORTNAME property of the serial object, but not sure how I would set that equal to the 2nd index of the combo box.
I am new in programing and I need some help setting the Enabled = True on a botton when selecting an item from a listbox.I have a project when I have and add a new record form and an edit record form, in the form I have added a listbox where displaying the name of the file that I am attaching, but I have also added a delete button on the form, When I load the form I have the delete button disabled:
HTML Me.BtnDelete.Enabled = False But I would like to do is that when I select an item from the listbox for the delete button to enable.
This is what I have but doesn't seem to work:
HTML If ListBox1.SelectedItem = True Then Me.BtnDelete.Enabled = True End If
When i select an item in my combobox it raises the following errorColumn 'field1, field2' is constrained to be unique. Value 'test1, 1' is already present.The combobox is bound to the table to populate it with values from field1 witch is the first part of primary key of the table. (field2 is secont part of primary key).
Here's how I'm trying to manually select a specific item in my combobox. cbEditCategory.SelectedIndex = cdEditCategory.Items.IndexOf(editItemCategory) I setup a msgbox to show "cdEditCategory.Items.IndexOf(editItemCategory)" and it's reporting -1. Why is it not giving me the right index?
I'm trying to automate a form process from a previous employee. One of the things that I have to do to achieve this is select a COM port from a dynamically populated list. I've looked around and the closest thing I could come up with is something like:
.cbbCOMPorts.SelectedItem(1) = True
While this compiles, the computer does not like this at run-time. It throws an exception out:
My program that I'm creating is a quiz creation tool, based for teachers to create quizzes and then use them to aid with quizzing their students.I've got the whole program working in that you can create quiz, play the quiz and then see how many questions were answers correctly and how many questions their were The problem I'm having is that I don't know how I can save multiple quizzes, for example you can create one quiz, that then saves as a .txt in debug however, when you then create another quiz and click the save file the old quiz details are sitting in the .txt
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click Dim filename As String 'full file/path name for QuizRecords.txt Dim index As Short 'loop control variable
[code]....
So what I'd like it to do is, when saved create another text file? Or another set of data questions, I have been looking through my Computing projects in Visual Basic . NET book as well as through online but I can't find anything that I understand as such.
I got a Combobox with some items (item1-item7) to select and 54ish Buttons(sButton1-sButton54). Also an array(53) called Buttons. The array is filled with the items to select, like: Buttons(0) = "item 1, item 2" Everytime another item in the Combobox is selected, I'd like only some of the Buttons to change their Image. Therefore I got the array. If Item 1 is selected and Buttons(0) contains the item1 I'd like to change the Button1's image.edit: It works with changing the image of every Button:
sButton1.Image = My.Resources.image1
But I'd prefer to change all in one go (Loop) instead.
I am new to programming and i am working on a windows fom app. In this moment i have my windows form set with several controls that insert data into sql db. Now, what i need is this:
When the user select a employee name from my dropdownlist, i want the form automatically fill with the data inserted in the past to the tables db. Is like choosing the different profiles by selecting the name in the dropdownlist. I have many controls to fill, name, secondname, lastname, telmobil, address, etc.
I know I can open the control panel item by using the following command %windir%system32SystemPropertiesPerformance.exe. However what I do not know is there a way to programmatically select the options on that control panel item? For example in a vb program I can launch that panel quietly have the program select "adjust for best performance" or select "let windows decide" Apply it and then close ?
I have a Private Sub that I execute whenever a user clicks one of two or three things, and in it I create a new tab in my TabControl. Once the new tab has been created, I select it then add a formatted textbox to it. However, it is not selecting the new tab and therefore only adding the rich text box into the already selected tab (not displayed, of course, because it has a dock style of Fill.) Here iis my code to select the new tab and format / edit the rich text box:
Try tabMain.SelectedTab = tabMain.TabPages.Item(intTabIndex) 'Select the new tab AddHandler rtbCode.TextChanged, AddressOf DisplayUpdate 'Add TextChanged event to handle updates
How someone would select an item from a list box and click a button and have that item go into another listbox with it's price? I seem to be stuck on this part.
Here's my code:
I want to select the first option from the first listbox and I want to put it into another listbox along with the price of that item on the same line in the listbox. I can't seem to figure out how to that.
Public Class Form1 Const dcmPRICE_STRESS As Decimal = CDec(595.0) Const dcmPRICE_TIME_MANAGMENT As Decimal = 695
I have a simple ASPX page with a listbox and a button. Listbox has about 8-10 items in it. After the user selects an item (listbox is multi-select) and clicks the button, I'm iterating through the items to get the selected one like so:
For Each Item As ListItem In lstLetters.Items If Item.Selected Then Dim LetterID As String[code]....
When I step through the code, I select the first item from the listbox. I setup a watch on the 'Item' variable. The code will iterate through each of the items -- but Item.Selected always reads 'False'.I double-check the page, and sure enough my item is selected on the form.What the heck is going on?
I know that the web's full of Q's and A's about how to use IsPostBack when selecting the value of a listbox.I have a stored procedure that returns a few values, and I want in runtime to have all the values be selected in the listbox.But when I loop through the SqlDataReader and do: listbox. Selected Value = reader(0), the final result on the browser is that only the last value gets selected.The listbox's SelectionMode is "Multiple".
