I just wanna ask how can i add, delete record in datagrid that is bind in a textbox using ms-access.
how to populate listbox from ms-access database.
Is there a way in which I can populate my listbox with an Access (.mdb) database and search for values in it. Also, can I move selected values back & forth from that listbox to another listbox (or textbox). Is this possible using Visual Studio, VB.Net?
View 6 RepliesI need to populate data (Patient ID and name) from a MS Access Database table (PetientInfo) into a listbox depending on date (Datetimepicker). The listbox item will change upon date changed.
When I select a item from listbox the details of the patient will show to the textboxes.
I would like to populat the Listbox collection from a column from a Access database I already created the name of the collection as collections. I can autocomplete/Suggest a Textbox with no issues.[code]
View 2 RepliesI have an accdb named base.accdb in the root folder of the program. Basically I have several tables in my database and I need to show their values in listboxes (essentially allowing menus to be edited by adding/removing items in the table)I can't figure out how to connect the database (according to my friends/classmates), and i can't figure out how to pull the information from the table.
Ultimately, it would be nice if someone could tell me how I can pull out the information into maybe an array? so that if i add 3 items into the table, then it will create 3 variables in the program and put the values from the table into those variables.
I'm using a OleDB connection to a access database. I'm entering a row into the database to set some user preferences. What i need to get is get back the row ID of the row I just entered. I'm more familiar with PHP and with PHP I use use this entry

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:

My Access database has one column named 'Term' and the Table name is 'ATG'. I require to populate my listbox with data in the 'Term' columns. I'm unable to do that using this code. Can anyone tell me what's wrong with this (it displays numbers from 1 to 10 and not the database data)

I have an Access table ("Titles") which is connected to VB.Net using OleDb. The connection variable is conTitles.Some of the column in the table are 'No' and 'Status'.

View 6 RepliesI've given up on my harder stuff and have simplified it to something else. There are no errors that pop up now but the list box doesn't populate! I took the code from a book and there's a data adapter, data connection, and data set on the form already (they're not named in this code though, since the book didn't say to). When the program opens, the list box has a line of text in it and the list box doesn't fill with the right items.

I've recently made another question about connecting to MS-ACCESS database with .NET in C# or VB.NET. It worked just as intended with MDB, but with accdb it caused an exception in
conn.Open();which follows:
Is there another way to do this? My original intention (like stated in the original question) is gathering some (actually, a lot of) fields.

If File.Exists(ExportFolder + "" + Tech_TextBox.Text + ".pdf") Then
txtRouted.Text = txtRouted.Text + vbLf + Tech_TextBox.Text

I have created an auto emailer to distribute our work routes for my colleagues. Problem is I made it easy for the management team to update the list. List is ordered by Tech Number, First name, Last name, Email address.
I have coded this in VB.NET 2008 using Database sources and drag-n-drop the table on the form. I let VB do most of the coding of the connection and text boxes. (IE If (Tech_TextBox.Text <> "9999") Then)What I would like to do, instead of using a bogus tech number as an exit. I need an 'IF Then" or 'DO UNTIL' after last record.
Populating a listbox with data from a database
View 2 RepliesI am developing a Windows application in Visual Studio 2005, V2.0 using VB.NET.I am coding part of an Emergency Response Information System. On my form, I have two combo boxes (cboBaseStationID and cboPriority). I am trying to populate the datagrid with records from my database based on what is selected in both comboboxes. For the first combobox, the user selects a name so the datagrid must only show records with that name. For the second combobox, this is a little more complicated. There are four emergency priorities in the combobox that the user can choose - 1, 2, 3, 4. In the database, there are different response teams (to be dispatched to these emergencies) and each response team has a grade of either 1, 2 or 3. So a grade 1 team can respond to emergency priorities of 1 and 2.A grade 2 team can respond to emergency priorities of 1, 2 and 3.A grade 3 team can respond to emergency priorities of 1, 2, 3 and 4.
So basically, if the user selects emergency priority of '4', then only grade 3 teams can be displayed. I am using two different tables in the datagrid. The datagrid is populating at the moment, but not based on anything that is selected in the comboboxes. It just displays a lot of duplicates of all the records in the tables. Here is my code so far (this code is on the search button click - I have already loaded items into the comboboxes on the form's load event):
Dim sqlConn As New OleDb.OleDbConnection
Dim sqlCmd As New OleDb.OleDbCommand
Dim sqlReader As OleDb.OleDbDataReader

i want to populate a listbox from a sql database and foll is the code i encountered error with:

This is some of my code. But how do I populate a datagridview using the datareader.
Dim strSQL As String = "SELECT peopleid,firstnames,surname FROM people;"
Dim cmd As New MySqlCommand(strSQL, con)
'cmd.Parameters.AddWithValue("Parameter1", strName)
Dim reader As MySqlDataReader = cmd.ExecuteReader
and how can I handle null field values.
I am trying to make an oledb connection to an Access database.
1. I added a component class.It said drag from the toolbox to add components.
2. I dragged over the Oledbconnection and OledbdataAdapter
3. I clicked on new connection string for the oldeb Connection and try to connect to the SHX.mdb datababase in the debug/ bin folder I don't have a username or password for the database and do not want to set one up.( is this possible in .net?)
4.As soon as I try to test the connection, I get the "invalid authorization specification" message. I can't get past this and do not really understand why I am getting this message.I have vb 2005 standard edition, not express edition.The exact same thing happens when I try to set up the data adapter to the shx.mdb database.
I am on XP2 and not logged in with a password or username. Could this be the issue or is there something else I am overlooking.Also, since I am coming from vb6 and ADO is there anyway to just write the code without having to use datasets, adapters and oledb connections to bound controls?
I have inherited some code from an external contractor that I have to modify. Firstly, he uses a strongly typed dataset to retrieve some data from an SQL database and then uses that data to populate a listbox. I have decided to use a dropdown list (as the user can only ever select one value at a time).This is the code that populates the DropDownList
Private Sub FillUserComputer(ByVal userId As String)
Try
TraceDebug("Begin FillUserComputer"[code]....
This works well for the first two entries in the DropDownList. However, whenever I select one of the other options and click the Send Request button it "jumps back" to the 2nd entry in the list and sends that data instead, completely ignoring the option I selected.I think I have narrowed down the problem to the fact that the DataValue for the second entry in the list is a Null value.
My current code only selects a single item from a specific field. How do I make it populate the listbox with ALL the items in a field?
Try
conn.ConnectionString = "server=; username=; password= database="
conn.Open()
Dim sqlAdapter As New MySqlDataAdapter

I am not sure how to phrase my question properly but I want to achieve something like this.

I am trying to populate one column in an Access table using two check boxes - one for 0, one for 10. How do I make it so that on click or after update, whichever check box is checked populates the cell with the associated number?
