Use Labels Dynamically And Populate Them From A Dataset?
Mar 8, 2011
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.

user control, I'm dynamically creating an arrary of several labels within a groupbox on the controls form. This is done in the load event.The user control is then placed on the form of mainapplication and then run. My problem being that the labels are invisiblen I launch the app. The visible property for the labels is set to true during the creation of the controls.

My current project involves displaying questions/answers from two different databases to be used to compare values and make judgements. The number of questions, choices, and answers is all variable. Thus I am attempting to create labels dynamically to show the information on the screen and create textboxes to leave comments. My problem is not knowing how to then access these lables, since I can't code in to use "label_comments" & (i) as it doesn't exist (at least, I can't get it to work).
First, my code for creating and displaying the information:
db_connection = New SqlConnection(ConfigurationSettings.AppSettings("ConnectionStringMerrill3"))
db_connection.Open()

I'm creating a series of labels at run time based on an array of strings made earlier in the program, but when i run, the labels aren't showing. The program is form based and the co-ordinates for the new labels are well within the bounds of the formHere's the code I'm using:
For i = 0 To 10
Dim lbl As Label
lbl = New Label

This may be simple, but im having a tough go at it. I'm trying to make a "review" section in a step through form, where the user can see everything that has been entered and if they choose go back and "edit" that information again. One section only has to show the information that has been added by the user, basically if they don't select a certain checkbox there is no reason to display the info for that box.I want to to dynamically create labels in a Panel (Panel7) on a TabPage (TabPage3), only for the checkbox information that was selected. This is what I have right now, and I am unable to see anything on the page, I have also tried without the panel and straight onto the tabpage itself to no avail.
MsgBox(CurPat, MsgBoxStyle.Critical)
If (CurPat = "True") Then
Dim lblTemp As New Label

I have a form that has an array of dynamically created labels of varying size based on a search from a database. The problem I'm having is that when the user searches for a different term, it looks like some of the labels don't get new values. Here's my code for adding the labels:
If rdr.HasRows Then
ReDim Preserve entities(cnt)
While rdr.Read()
[Code].....
I've tried for loop over the controls in panel1 to dispose of any still on there in both the page_load and page_init subs, but neither had an effect. I don't know if it might have something to do with controls having the same IDs after the postback.

I'm currently making an application that involves time tables / scheduling. I'm required to generate a timetable for school teaching activities. in this application, I want to display the time slots using labels and I want to enable users to drag them around to place the subject cards in the available slots. I'm even confused with the control to use for the time slots. Right now I'm thinking of using datagridview for the time slot. So I'm trying to drag the labels around and placing them in the datagridview cells.

I have made a program wherein you the labels are dynamically created with a press of a button. if you press on the label, the label would then change color from white to blue. my problem is that how will you make the backcolor of the label change when the button3 is pressed.
here are the codes. placed the whole thing since I dunno if you guys would understand what I mean.

PS here is the link to what my program looks like. link to my program . the button3 in the image is Reserve Seat.

I have a windows form in VB.NET. In that I create two Comboboxes dynamically during runtime. Lets name them CB_A and CB_B. Now when these are created, CB_A is populated by calling the handler which is created while creating the control.I want to populate CB_B which will depend on the value selected in CB_A. e.g. The first value in CB_A will populate one set of values in CB_B while the second will populate another set and so on...The approach which I tried was get the name of the CB_A and then deduce the name of CB_B, but it does not recognise as it says it cannot change from string to objec(combobox).

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 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'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.
