Creating A Dynamic ComboBox Item Adder?

Jul 18, 2009

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.

Add To A Combobox A List Of Item (not Every Item) In A Txt Located On A Server

Feb 13, 2011

my program downloads into a combobox every item(line) that is in a text file located on a server.
Every line in the text file ends with "a)" or with "g)".

Now I just want to make 3 radio buttons:

- one that will allow the download in the combobox only the item ending with "g)"
- one that will allow the download in the combobox only the item ending with "a)"
- one that will allow the download in the combobox of both (I already know how to do).

How can I do so?

To download the entire list in the combobox I do:

Dim List As String = client.DownloadString("http://mywebsite.com/mytextfile.txt)Dim lines As String() = List.Split(New String() {ControlChars.CrLf}, StringSplitOptions.RemoveEmptyEntries)ComboBox1.Items.Clear()
ComboBox1.Items.AddRange(lines)

Change List Of Combobox A Based On Item Chosen From Combobox B?

Jun 17, 2011

I am new to vb.net and I am using visual studio 2010. I have two comboboxes on a form, each combobox is set to DropDownList so that a list of items can show in the combobox, but no text is allowed to be entered.

For combobox A, if user chooses item 1, the list of combobox B should be updated accordingly. I think this is quite common on a lot of applications. But I do not know to implement it. I even do not know the keyword to search for the relevant property or event handler.

I have a VB.Net WinForm Program. I dynamically create panels with controls.Each panel has:

2 Labels

Everything gets created, and everything is functional.

Get Text From Dynamic Drop-down Item?

Jun 18, 2010

My program populates a drop-down menu with items dynamically at runtime. The items listed are the currently running windows and applications seen in the Windows taskbar. I was wondering if there was a way to retrieve the text of a selected menu item during runtime and use it to set focus to that application or window (which is the text of the selected menu item). I have looked at using the AppActive function to achieve this. I just don't know how to retrieve the text of the dynamically created menu items. Please keep in mind that I am an amateur coder so my code might look stupid. I have tried the following code block with no success:

Private Sub AppActive(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CurrentlyOpenedWindowsToolStripMenuItem.DropDownItemClicked
AppActivate((Me.CurrentlyOpenedWindowsToolStripMenuItem.DropDown.Items.Item(Text.ToString)))
End Sub
Should I be using the SetForeGroundWindow API instead?

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?

Creating Dynamic Control Array In VB 2010

Oct 31, 2011

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?

Dynamic Creation Of Picture Boxes, Buttons, And Labels For Each Item

Apr 7, 2011

I'm currently working on a program where I'm trying to dynamically create a picture box, a button, and a label for each item in a text file. Any ideas on how to do this? What I have: a plain text file with a list of numbers. Each number corresponds to a location. When that file is read, I want to create a picture box, a button, and a label related to each number. If I want to add something to the screen, all I Have to do is add a number to the file. So, lets say the file has. 1, 2

When the file loads, it will create a unique item on the display for each location. say pic1, button1, and label1 and pic2, button2, and label2. Right now, if I add something to the file, I have to go back into the editor and manually add everything. Which is a pain.
