Populate Label Text From LIstbox DataSet?
Aug 17, 2010
I have a listbox with a dataset and a query that is used to populate the listbox. Now, depending on the selection of the listbox. I want to populate a variety of labels with specific information from the dataset with the selected listbox item as the key. Here is the code I have so far... but I am unsure how to continue....
Public Class frmItemsToCal
Private Sub frmItemsToCal_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'BISEMv2DataSet.Equipment' table. You can move, or remove it, as needed.
Me.EquipmentTableAdapter.Fill(Me.BISEMv2DataSet.Equipment)
[code]....

i have a Userform that I created in MS Word that automates almost half my job. I'm just looking to re-create this form in VB.Net so that I can keep up with the trends.What I did previously was load a listbox based on the contents of a data table in another word document. I've searched for other methods of creating a datasource in VB 2010 Express but I'm unsure how to load the contents of a dataset or datatable as opposed to a table from MS Word. Ideally, I'd like to abandon using Word tables and create a dataset in VB and load a listbox based on that. I do not have a copy of MS Access and I'm unfamiliar with MySql, which I'm guessing would are the easiest methods of loading a dataset. I also thought that maybe if I could create a seperate form (let's just call it form1) specifically for entering new data and saving the form as data is added, then linking the datasource from that form to a second form (form2) that has the listbox that will populate with the contents from the data in form1.

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.

I am just wondering how I can make a listbox count the number of selected items and display it in a text label. My listbox selection mode is on MultiExtended.
Also, can someone provide the definitions for:
SelectedItem
SelectedIndex
TabIndex

I am trying to populate a dataset from an XML file. Within the xml file are some € signs. However, when the data is read from the XML, the € sign is displayed as a ?. Has anyone seen this behaviour before, and if so do you know how to correct this? Below is a copy of the code i use to read the data from the xml file:

I'm trying to populate a combo box with a dataset, this sort of works, but everything is just appearing on the same line. I think this answer might be to put the dataset into an array, then put the array into the combo box.
...problem is, I'm not sure how to do this! My code thus far is,
Dim usernameList As Array
'Retrieve usernames where player has available status
GetFilteredData()

My problem is that I can't populate a datgrid with the contents of a dataset. Having searched for the last few days to try and resolve this, I have given up and thought I would try here. I am using Visual Studio 2010 and attempting to create a WPF application. As you can tell from the code I am very new to this and any suggestions for improvement will be most welcome. I can see that the dataset is populated ok via the visualizer, I have a datagrid 'dgBOM' which I want to display the results. A popular solution in my searches was to add '.DataSource' but when I type the '.' after dgBOM the Datasource option is not there.
Code:
Public Sub Connect()
Dim cn As OleDbConnection
Dim cmd As OleDbCommand
Dim dr As OleDbDataReader

I have need for a database in my latest app, i quickly realised it had been a long time since i last used a database and am in fact very very rusty on the subject. So i decided to create a simple DataSet using the designer, i created 2 tables as follows
Table 1 is Named Map and contains a 2 dimensional array each cell containing an array of object id's of anything in that cell, and a level ID.
Table 2 contains data about these objects ie size weight and a z-order, again referenced by an object id (matching Table1)
This i did with no issues, when it came however to actually populating these tables i drew a blank. Do i have to locate the database file and edit with notepad? I presume not. Maybe i have to use an external app like sqlmanager? I seem to recall from my past that i added table rows from within the designer but i cannot find this in 2010 express

This is a problem I have been trying to conquer for some time now and haven't managed to deal with. I've looked pretty hard on Google and so on, but most of what I find there is for populating a TreeView from a database. The closest I got was a bit of C# code for populating with a list of file paths. But unfortunately the result is individual roots & branches for each item.
What I'm working on is a message template tool where I'm trying to get the nodes in the treeview, which represents the templates, to populate from an XML file. I'm using DataSets for their simplicity of working with XML. Here's a basic example of the structure of the XML which is imported to the DataSet;
Code:
<?xml version="1.0" standalone="yes"?>
<Templates>
<Item>
[Code].....
So the path to each node will look like RootBranchName. I know this will no doubt require some recursion, but recursion is one thing I haven't fully grasped yet.

I am using Visual Basic in Visual Studio Express 2008. I am creating a form that works with an Access database which has five tables, though for purposes of my problem I will only mention two of the tables: Customer and Project.
The Customer table contains basic customer info, with a unique ID auto-number. The Project table describes relationships between two customers. There is a Primary ID number and a Secondary ID number, both of which correspond to an ID number from the Customer table. Any given ID number can exist as a Primary or Secondary ID, so if "Bob's Company" ID is 1, and "Fred's Company" ID is 2, there can be two projects, one having "Bob's Company" as Primary and "Fred's Company" as Secondary, and the other vice versa.
The user navigates through the Customer table by means of a combo box. They choose one customer name from the box, which populates a label with that customer's ID number. I have a View Projects button with the intent that once the user chooses the company, they can click View Projects and a DataGrid will appear which contains only the records from the Project table in which this specific Customer number appears (either as Primary or Secondary). So basically, with all that explanation, I'm trying to figure out how to get the View Projects button to take the CustomerIDLabel.Text and use that to populate the DataGrid.[code]...

I have a simple access database that a log record gets written to a few times an hour.
I'm trying to make a DataGridView that shows that data as it arrives.
My "Solution" is simple;
when a user clicks the view -> read from the database (fill the datatable) -> update the view.
Not what I dreamed of, but functional, if totally sub-optimal.
However, my "solution" is a dud, using fill draws every single record from the database, even if there are already 599 on screen.
Really, I just want fill the datatable once, and add new records as they arrive (or on click if needs be).
Bonus point if you can also explain another way (that isn't called so often) to hide the ID column, and change the header of column 1 (named DateTimeStamp) to TimeStamp.
Public Class FormMain
Shared dataAdapter As OleDbDataAdapter
Shared logTable As New DataTable("log")

I am creating an electronic display board using Visual Studio 2005, this will be an application using VB and not web based.What I am trying to do is use labels dynamicly and populate them from a dataset, Now there is a lot of labels on this board and to be honest the perfect solution would be to use a Data Grid View, unfortuantly I have to fit the information into a Custom Graphic that was created, hence the reason for labels.So obliviously I dont want to have to name each label and specify its information, for example:
Code:
Label1.text = MyDataSet.Tables(0).Rows(0).Item(0)
Label2.text = MyDataSet.Tables(0).Rows(1).Item(0)
Label3.text = MyDataSet.Tables(0).Rows(2).Item(0)
So I thought about something as follows but not sure how to get it work.Say I new I had 100 Labels Label1 to Label100.
Code:
Dim i as Integer
For i = 1 to 100
[code]....
Now the above doesnt work but it doesnt throw up any errors either.

I'm having a little trouble figuring how to do this.I have a dataset with a single table. Each row has the following fields ProductName, Version, CompanyName
The data might look like this
Visual Studio, 2005, Microsoft
Visual Studio, 2008, Microsoft
Office, 2007, Microsoft
I have already populated the TreeView with a list of Company names from a separate table. Now, what I want to do is to loop through my dataset adding a single node for each product under the appropriate manufacturer. Then under each product adding a separate node for each version of that product.

I am attempting to discover how I can populate a ComboBox with the data values already located in a data source that has been added to my project. I know how to use the ComboBox.Add method. I also know how to add individual value items contained in a manually entered array at design time using the For Each Next loop. However, I am unable to populate a ComboBox with all values for a field of a table in a data source that has been added to my project. I assume that I am unaware of some simple referencing step that will solve this problem.

There's a thread that i'd read wherein you reply regarding on shortcut on populating a listview with databatable or dataset, but i forgot it. How did you populate a listview with datatable or dataset with just one line.
In datagridview .DataSource how about in listview ?

I don't have the same problem when using an untyped dataset.
OK. I have a typed dataset MyDS with a typed datatable MyTable (TableID, Title, Message).
The table gets filled with results from two tables, using a UNION ALL
Select
TableAID,
TableATitle,

Is this how typed datasets handles UNION? I didn't want to create two typed datatables and create separate SQL for each and create a relation.
