Use Datagridview / List-boxes Or Something Else To Display Records

Apr 25, 2012

I have created a database with a couple of records to get started, also I have attemted to implement the database in my forms. I want to add, delete, edit and save new records into the database so when I use it or re open the program the entered data will still be there. Also, after I have implemented these things, I would like to be able to import data from the database into textfields or comboboxes. I have a basic email client and I would like to import these contacts into the datafields. However, I will be trying to achieve that later.I am trying not to use the data connection wizards as I am learning the code as I go along. I have been reading up on databases for about 2 days not and i'm still struggling.This is to add contacts with the fields.I have 7 labels with text boxes, using the naming convention lblFName or txtFName etc;

-First Name,
-Last Name,
-Nickname,
-Email,
-Phone number,
-Address and
-DOB

I have 4 buttons;

-Add record
-Delete record
-Save record
-Next record
-Previous record

I don't know whether to use datagridview, listboxes or something else to display the records.This is to give you an idea of what I have done so far.However, I cannot find a way; despite my best efforts over the last 5 days to link the database that is located in the same folder as my program.If anyone could point me in the right direction on how to code this into my program, or post some links of which I can read, learn and understand the code.

Display Records Searched In Text Boxes To A Datagrid?

Jun 6, 2011

I am creating an application which will allow users to search parents names and display their childen respectively in a datagrid.I have created a form with two text boxes, a search button and a datagrid. The two text boxes are txtFName.text and txtLName.Text. On clicking btnSearch I want to be able to run a search to the SQL database for specific records.So far I have been sucessful in doing so with a listbox but I would prefer to have the data populating in a datagrid as it is more cleaner.

Here is the working code for displaying searched data in a listbox: Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click

VS 2008 - How To Display Records From Database Into Dropdown List

Mar 30, 2011

How to query a record in vb.net using combo or textbox via linq to sql like the search engine? Just like when you search in google or youtube, once you typed in the initial string on the textbox or combo box it will show a drop-down list. I tried to use it in my application using linq method but the problem is it would duplicate on the first string that you entered on the dropdown list if that record exist on your database after you press the space key. I used the code below which duplicates the records on the drop-down list when you type in your string after the space key.

I just want it to be like in any search engine that when you type in the string or your initial string, it will display on the drop-down list all the records from the database that contains the string you entered without duplication. In my case, I'm trying to query a name from my database. This is how it should work, For example, if you type an initial string in the textbox or combo box a named 'Mark', it should display all the names from the database containing 'Mark' into the drop-down list before it changes into its final string that you entered.

Here is the codes I used:
Private Sub ComboBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles
ComboBox1.TextChanged
Dim db As New MultipleDatabaseOperationDataContext
Dim search As String
search = ComboBox1.Text
[Code] .....

Selecting Values Of Combo Boxes And List Boxes In Web Browser?

May 22, 2012

I am developing a program that makes it easier for users to log on to a website and search for specific data. I have the first portion finished in which I have a form with the Ax Web Browser control.

The web browser control navigates to a local website and automatically logs in for the end user. This is done by using code which automatically fills in the username and password and then submits the form to logon using something similar to this: WebBrowser1.Document.Forms.Item(, 0).elements("txtUsername").value = "user"

Once logged on - there is a search page which contains a combo box and list box. I am trying to set specific values for the combo box and list boxes.For example - the combo box on the website is titled: cbxDate and contains the following values: Today, Yesterday, This Week, This Month.

A list box titled: lstArea contains the following values: Zone A, Zone B, Zone C, All.I am trying to figure out if there is a way through code to select, in this example, "Yesterday" in the cbxDate and "Zone B" in the lstArea on the webpage.If anyone knows of a solution, please feel free to let me know. Be advised that I am using the Ax Web Browser Control.

Placing Selected/unselected Items In Checked List Box Into List Boxes?

Mar 16, 2011

This program is supposed to allow the user to check items in a checked list box. If the item is checked, it goes into the Completed List Box on the right. The program then adds the unchecked items to the Pending list box on the left. I keep getting placement values (e.g. O,1,2) instead of the strings (e.g. "Key Returned") in the list box results (see photo attached)

Combo Box To List Boxes In VB?

Nov 30, 2009

I am trying to create a WPF browser application that allows you to search and display recipes. The combo box presents choices, the Ingredients display in one list box and the "cooking" instructions appear in the other list box. What's happening is the first time you make a selection from the combobox nothing displays, and this could be happening because the first line of code under Selectionchanged clears the List Boxes however, it should be populating those list boxes with content, shouldn't it? Anyway, as you make other selections List boxes 1 & 2 get populated but they do not match what displays in the Combo box, i.e. if you select "Easy Taco Dip" any random recipe might appear in List Boxes 1 & 2.

Option Explicit On
Class Page1
'User Makes a selection from the ComboBox which populates List Boxes 1 & 2

String Won't Display In Output Boxes?

Dec 5, 2011

The project was to modify a previous payroll system project, which had a base class(employee) and 3 derived classes(salary, commision,and base + commission) under it by adding 2 more derived classes(piecework and hourly).Before I stated the modification, everything worked fine. When I would run the program the 3 types of employees would display in each output text box. The same thing is supposed to happen after I added the 2 additional types of employees, but now when I run the program, both output text boxes are completely blank. I'm not sure why I can't get anything to display in my 2 output boxes and all of the coding looks correct to me.

Add Code To List Boxes Items?

Jan 31, 2012

I am surely a new self-learner programmer using VB 2010 Express edition and I have a problem on writing my first code. I have designed my form and I only want to add code as events. The IDE already adds the methods when I double-clicked the button which I want to add the code on.

This question may be good on the IDE forum, but I just thought to ask it here because there may be more experts here on VB language functions. I have added the MenuSctripItems such as File, Edit and so on. How do I write the code for New, Open, Save, etc under file menu? It may sound boring or even silly, but I am here to learn and your contribution is both for me, you and the MSDN.

I'm using the free version on Visual Basic 2008 (through school).The assignment is to populate a list box from user input text. The textbook only talks about populating a list of known items.ex animalListBox.Items.Add("dog") Which works just fine, however, we don't know what the user will input.

So, how should I be thinking about this?

If I'm trying to output to a listbox, what is the easiest way I can enter a string and then a variable on the same line? I'm trying to use listbox1.Items.Add(...). Obviously outputting a string is no problem and outputting a variable is no problem, but I want to add a string and then a variable after the string. For instance:

name = "Joe Smith"
listbox1.Items.Add("Name: ", name) [or something like this]
