Hi.
I am new to this site. I found an example of an image combobox by Alon Ronen. The code is as follows:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles MyBase.Load
Dim items(Me.ImageList1.Images.Count - 1) As String
For i As Int32 = 0 To Me.ImageList1.Images.Count - 1
items(i) = "Item " & i.ToString
Next
Me.ComboBox1.Items.AddRange(items)
Me.ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList
Me.ComboBox1.DrawMode = DrawMode.OwnerDrawVariable
Me.ComboBox1.ItemHeight = Me.ImageList1.ImageSize.Height
Me.ComboBox1.Width = Me.ImageList1.ImageSize.Width + 200
Me.ComboBox1.MaxDropDownItems = Me.ImageList1.Images.Count
End Sub
Private Sub ComboBox1_DrawItem(ByVal sender As Object, ByVal e As _
System.Windows.Forms.DrawItemEventArgs) _
Handles ComboBox1.DrawItem
If e.Index <> -1 Then
e.Graphics.DrawImage(Me.ImageList1.Images(e.Index), _
e.Bounds.Left, e.Bounds.Top)
End If
End Sub
Private Sub ComboBox1_MeasureItem(ByVal sender As Object, ByVal e As _
System.Windows.Forms.MeasureItemEventArgs) _
Handles ComboBox1.MeasureItem
e.ItemHeight = Me.ImageList1.ImageSize.Height
e.ItemWidth = Me.ImageList1.ImageSize.Width
End Sub
I would ask the author about this code but I cannot figure out how to contact the author. My question is how I would add text to this combobox. I want a box with images and a line of text as a kind of descriptor. Any ideas?

Hi, I am new to .Net and working with threads for the first time. Please review the code below.
Dim t As Thread
t = New Thread(AddressOf Me.GetValue) ' GetValue is a procedure
t.Start()
In GetValue, I want to get some data from the DB and fill in a combobox. However, when the following code in GetValue executes -
str = "select ID from ABC"
DA = New OleDbDataAdapter(str, ipcon)
DS = New DataSet
DA.Fill(DS, "rec")
- the control is lost. i.e: the next set of statements (to fill the combobox with the dataset values) do not execute. I am not sure why such a thing is happening. Is there some way to handle this threading issue that I am missing? Please help.
With Best Regards,
Mayur

Try Instantiating the Datatable on the main thread before you start the second thread:
<br />
Dim dt As New DataTable("dt")<br />
<br />
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click<br />
Dim thrFillTable As New Threading.Thread(AddressOf FillTable)<br />
thrFillTable.Start()<br />
End Sub<br />
<br />
Private Sub FillTable()<br />
Dim c1 As New DataColumn("Number")<br />
dt.Columns.Add(c1)<br />
Dim dr As DataRow<br />
For i As Integer = 0 To 10<br />
dr = dt.NewRow<br />
dr.Item(0) = i.ToString<br />
dt.Rows.Add(dr)<br />
'Next line is just to waste time <br />
'so you will see combo has no data <br />
'till thread Is finished<br />
Threading.Thread.Sleep(2000)<br />
Next<br />
Me.ComboBox1.DataSource = dt<br />
Me.ComboBox1.DisplayMember = "Number"<br />
End Sub<br />
<br />
<br />

ya thats y wanna know anyone have other device cause i only know use the mediaplayer... u have any clue?
|

Media Player will only play one thing at a time, so you'll have to use a library that can do mroe than that, like DirectX and it's DirectSound library.
Sorry, I don't have any examples because that's no my area of expertise or development work. Google should be able to get you hundreds of examples though.

In every DirectX game I've every played... And without using MediaPlayer.
It's not a problem with VB.NET. It's a problem with the audio library your using. Perhaps searching for DirectSound examples might help?

I have no idea. DirectX isn't my area of expertise.

I also need a help with that.
I need the create a background sound and a sound for the game I am developing.
So far I can only import the DirectX libraries and that is it.
I know I have do create a directX device and full stop. And How?
Help is very much appreciated.

First, you're replying to posts that are VERY old.
Second, read my post again - I'm not an expert in DirectX at all. I have not idea how to do this.

No, but apparently you have. The answer he gave you is a little sparse, but essentially correct.
You can position the ComboBox anywhere on the form using its Left and Top properties, or both at once using its Location property.
If the ComboBox is behind another control, you can bring it to the top by calling its BringToFront method. You might also have to set its Visible property to True you already have this ComboBox on the form and are hiding it.
If not, you'll have to create the ComboBox dynamically, you can, but you also have to add it to the form's Controls collection and wire up any events that you want to handle by hand, using AddHandler and RemoveHandler.

Like Steve said, you're acting like one.
On top of that, you're asking questions on the level of one too. Maybe if you included a bit more detail about exactly what you're having a problem with, you wouldn't get the "shotgun" answer that covers all the basics.

Steve Sorry...
The problem is that i am from croatia and its hard to me to explain it on english wery good... I am trying buth its not easy...

My problem is that i want that the listbox shows when i press key"<" buth i want that it shows on the possition where was i typing where was the cursor buth not the mouse cursor, typing cursor(IBeam).
I did make it like this...
When key "<" is pressed if
listbox1.visible=true then<br />
listbox1.visible=false <br />
elseif listbox1.visible=false then<br />
listbox1.visible=true
buth the problem is that it is allways on possition where i place it in design.

Perhaps you should read the documentation on the RichTextBox more, RichTextBox.GetPositionFromCharIndex[^].
This will return the position of any character, relative to the top-left corner of the RTB window. You'll have to do a little math to get the position of where you should position your listbox relative to the top-left corner of the Form.

Hi All,
I have posted this like hundred times and i seem to get no response from any. i am again refining my question hope that makes clear.
I have a data repeater in my webpage. which basically queries 3 tables and combines and repeats accordingly. but what i have in one table is a statatistical data like
id estimated actual year
1 20 18 2003-2004
1 23 21 2003-2004
1 24 14 2005-2006
2 20 24 2003-2004
2 15 29 2003-2004
2 16 14 2004-2005
3
4
7
etc.
missing IDs are present in other TABLES just not in statistical table.
i need to create individual chart for id 1 for year 2003-2004 and year 2005-2006 and so on for id 2 and so forth.
i can create once chart based upon a single table but its like a quering a table and based upon parameter i need to create new dataset and bind it to some web chart control.
the data should be presented something like this in a repeater.
Head information related to ID 1 from table 1
sub head description related to ID 1 from table 2
a chart for ID 1 of year 2003-2004 and a chart for ID 1 of year 2005-2005
(if no data present dont display chart)
so on for other IDs.
Please help how to achieve this or do you know any Software that does this so that i can simply purchase this software.
thanks
Robin
