I need the ability to create a dynamic number of hotspots in an imagemap the pseudo code for what I want to do is below:
Protected Sub AddHotSpot()
Dim r1 New RectangleHotSpot
For Each Item as datarow in dataset
[Code]....
not too sure if i posted at the correct place. but anyway.. here's my problem. i'm using vb web developer 2008. i'm trying to pull out data and display using the imagemap/hotspots. for example, when i search for this item 1, it will pull out the data from the database and then shows me where the item is placed on the map.

I have a VB.Net WinForm Program. I dynamically create panels with controls.Each panel has:
2 Labels
1 DataGridView
1 Button
Everything works fine the first time I create the panels.
Everything gets created, and everything is functional.
If I have to re-create the form, I get rid of the existing panels (and their controls) with this code:

When I re-create the panels, I get the panels and all of their controls except Buttons.When I step through the debugger, I see the buttons being removed, and I see them being created, but they don't appear in the panel

I am writing an application that requires button controls to be created at run time because the amoutn of controls created depends on data retrieved from a database.

myButton = New Button
myButton.id = "id"

I am looking at creating a Dynamic Menustrip.I have managed to write the code to add subItems to a Item. The root item is called item1 and when the form is run, item1 gets populated by items called subItem[0-5].I am wondering how do I assign an action to a subItem when click? At the moment I want a message box to popup with the subItem's name that has been clicked. I.E If subItem3 is clicked, I want a msgbox to pop up with "subItem3".

Dim subItem As String = String.Format("subItem{0}", j.ToString())

I am trying to create a dynamic dropdown after a dropdown has been selested (in asp.net vb)
For example: I have a dropdown question that asks: What brand of car do you drive (Toyota, Ford, Honda, Nissan, Chevrolet)
When the brand is selected I want another dropdown to appear under it with new chocies
For example: If Nissan is chosen, the second dropdown will be populated (from the database) with (Altima, Maxima, etc...)
And in some cases I would like a text box to appear, but If I can figure out the dropdown portion, I am sure I can figure out the textbox.
What Im trying to do is create a function that sees how many items Im wanting to add, then add each item to the combo box, without me having to add each item individually. Basically its to save space coding, and make my code easier to follow.
An example of what Ive got is:
Dim option_one As String = "Inches"
Dim option_two As String = "Feet"
Dim option_three As String = "cm"
Dim option_four As String = "mm"
[code]....
So the function would go instead of all those add items, and it would just say Call ItemFunction() or something like that.
I had been searching as to how I could create an array of controls dynamically, and after some searching found some helpful code as shown below [code]This way in the above code "structureComboBoxes" will have an array of comboBoxes (VB6.0 was way easy to get this crap done!! I guess its cleaner here)Now my next problem is How do i code for events of each of these combo boxes?
View 6 RepliesI have a SQL database which I'm running a query against to return a list of names - eg using "select names from table"I would like to add all of these names to an array so I can use them later. To do this I would need to use a dynamic array as the number of names returned could be anything.Apart from first running "select count(names) from table", getting a value and then Redim'ing the array on the count is there another method I can use.I've seen there's a dataset row.count? Can I somehow use this?

I need to dynamically create some sort of 'table' on my form. It should look like:
PIC1 INTEGER1 TIME1
PIC2 INTEGER2 TIME2
PIC3 INTEGER3 TIME3
On top of that it should look like a table and have gridlines between the 'cells' containing the picture/data, which makes it even more difficult for me. Before, control arrays were quite simple in VB6, but I've been searching for 1,5 hours now and I can't figure out how to do this in VB.NET 2010. Any idea how to tackle this the most efficiently?

I need to create some serial port controlls manually. My program reads through a config file, and it if comes across an entry called COMPORT then I need to create a contol to talk to this port. The entries in the ini file might be
COMPORT=COM1
COMPORT=COM3
COMPORT=COM7
So here is my problem! I'd like to create the variable control name with part of the com port number, so I can always refer back to it.
EG.
Dim strVar as sring = "COM1"
Dim CName+strVar As New System.IO.Ports.SerialPort
I am looking to create an order reference which is something like this
PLC0000001
Where the 1 would be my order id
but lets say it gets to 100 would like

In VB.NET how could I build up a string like where i know i.e.
the starting part = PLC
Ending part = Order ID
middle = fill in 0's

I am a beginner developer. I am developing a website. I have few divs which made up dragable boxes enhanced by jquery portlets. see the codes below.(html).
<div class="portlet">
<div class="portlet-header"> Category A </div>
<div class="portlet-content">
[Code]....
I also have a stored procedure from the database developer that return the list of categories. Depending on the user selection, the list of categories can vary.
So i have to dynamically create those Boxes. Each categories returned by the SP should replace Category A, Category B, and so on. As i can't know the number of categories returned by the SP i just hard coded those divs. My question is simply how ? How can i achieve this?

i have created a dynamic tabpage and a dynamic tablelayoutpanel inside it then added dynamic textboxes and labels inside the tablelayoutpanel...the thing is , i am having a problem on how to access the value of those textboxes and labels and add them as new columns in the new table(tagpage) in mysql database, i can already create the table in the database but i cant add the new columns in it. heres the code for accessing the values of the labels and textboxes

I need to represent the following query using LINQ:
DECLARE @PurchasedInventoryItemID Int = 2
DECLARE @PurchasedInventorySectionID Int = 0
DECLARE @PurchasedInventoryItem_PurchasingCategoryID Int = 3
DECLARE @PurchasedInventorySection_PurchasingCategoryID Int = 0
[code]....
Now, I know that a query in .NET doesnt look like this, this is my test in the SQL Design Studio. Naturally VB.NET variables will be used in place of the SQL local variables.My problem is this: All of the conditions after "WHERE" are optional. In that a query might be made that uses one, some, all, or none of the conditions. V.PropertyID and V.Value can also appear any number of times.In VB.NET I can make this query easy enough by simply concatenating strings, and using a loop to append the "V.PropertyID/V.Value" conditions.I can also make a Stored Procedure in MS SQL, which is easy enough.However, I want to accomplish this using LINQ.
Ive managed to dynamically create a form, and dynamically create a timer, but i have not been able to create the timer on the dynamic form. Specifically, i need to be able to have the timer itself create another form with a timer. (I realize that this would create a new form every interval on the timer, that is what i want to do)
1. A way to add the timer to the dynamic form, and maintain the timer sub on my main form.
2. A way to create the whole thing over (dynamic form and timer) through the previous dynamic form and timer.
I was thinking i could use a collection/array to store the forms and timers, but i'm still having trouble figuring out how to add entire forms or timers into a list. (A timer is not considered a control, so i cant use a controlcollection...)
Heres my code;
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim frm As New Form
[Code]....
*EDIT* Btw, my idea was to use i as a variable that increases every time a form is created, then insert the form into the array, with i as the integer. i just need to know how to create a new form with a different name each time. (as with timers)
