Are you sure your looking at the right property. RecordCount should and is Read-Only for a reason.
What are you attempting to accomplish by changing the RecordCount property?

Hi all,
I'll try to explain what I want to do. I'm starting to learn about arrays and I'm trying (and failing all day) to be able to create a list in a dropdown menu of filmtypes: "Comedy" "Thriller etc.
When I select one of them "Comedy" for example I want that to appear in the list below.
I've attached the code I've written so far:
hope someone can help.
thanks,
Chris
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
With ComboBoxSelectType.Items
.Add("Comedy")
.Add("Thriller")
.Add("Horror")
.Add("Animation")
End With
End Sub
Private Sub ComboBoxSelectType_SelectedValueChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBoxSelectType.SelectedValueChanged
Dim Comedy(5) As String
Comedy(0) = "The Best of Jasper Carrot"
Comedy(1) = "Goldmember"
Comedy(2) = "The Man Who Sued God"
Comedy(3) = "The Life of Brian"
Comedy(4) = "24 Carrot Gold"
Comedy(5) = "Peter Kay"
If ComboBoxSelectType.SelectedItem Is Comedy Then
ListBoxAvailableDVDs. = Comedy
End If
thanks,
Chris

First, the following line does not make sense.
chrischik wrote: If ComboBoxSelectType.SelectedItem Is Comedy Then
Keyword "Is" is used to check if 2 references refer to the same object. In this case, they're 2 completely different classes which will cause the above code to always evaluate False.
You see SelectedItem will return a String reference because that's what you added into the ComboBox in Form_Load. Comedy is an Array reference.
Second, I don't think you need to use an array at all in this case. It looks like you just want to add the selected ComboBox string into your ListBox. So, why not do this?
Private Sub ComboBoxSelectType_SelectedValueChanged(ByVal sender As Object, _
ByVal e As System.EventArgs) Handles ComboBoxSelectType.SelectedValueChanged
If (ComboBoxSelectType.SelectedIndex >= 0) Then
ListBoxAvailableDVDs.Items.Add(ComboBoxSelectType.SelectedItem)
End If
End Sub
|

If you are looking for the "error" then the line:
If ComboBoxSelectType.SelectedItem Is Comedy Then
has to be changed in one of those:
If ComboBoxSelectType.Text = "Comedy" Then
or
If ComboBoxSelectType.SelectedIndex = nn then ' (where nn is the array index)
Also I don't understand this line (and surely doesn't compile):
ListBoxAvailableDVDs. = Comedy
If you want a suggestion you can also go for:
select case ComboBoxSelectType.Text<br />
case "Comedy"<br />
' Code to handle this case<br />
case "Thriller"<br />
' Code for thriller<br />
...<br />
end select

Oops. Good catch Briga. I answered this way to quickly and forgot the DVD titles under Comedy.

Hey everyone
I am new to VB. I need to do a small project where I need to make a real-time graph from the data in a database. What I need to do is to query the database every minute to count the number of records present there and plot the difference of the new count and the previous count on Y axis and the time elapsed on X-axis.
Thanks

I highly recommend the Zed Graph control. It is a free, very nice, professional looking control.

You'll also need to setup a timer control on your form with a 1 minute interval. Every time it elapses, you should fetch data from your database and then rebuild the graph control with this data.

So does zed control work with VB 6.0 ?
Joshua Quick wrote: You'll also need to setup a timer control on your form ...
The timer and the data fetching from the database is already working. Now what I need is just how to scroll the graph to the left every minute and update the curve.
Thanks

Hello coders,
I am looking for a way to develop a Header Column with a ComboBox Dropdown button.
A sample is shown in here..
http://img510.imageshack.us/my.php?image=headerwithcombo4ge.jpg
Please help me if you know a way to develop that (it could be only a message to be sent to header or another control)
Thanks.
Best Regards

You can create a UserControl to do this, but that is quite a bit of work and advanced.
You can try to find a control with similar functionality, such as this one...
http://www.codeproject.com/cs/miscctrl/listviewfilter.asp[^]
Or an even easier solution would be to break it up into separate controls. You could create several ComboBox controls next to a ListView control. You would then capture the ComboBox's SelectedIndexChanged event to update the ListView.

Thank you for your answer
I have thought that before, but I am not going to use the headers in a listview.
Thanks anyway
Best Regards

How and where are you displaying the MDI form?
Are you displaying the MDI form modally from your login form? If so, then that would prevent you from closing your login form. Instead, you should first let your login dialog close first (say via an OK button) and then display the MDI form modally.
If your startup object is your login form, then I suggest that you change it to "Sub Main" and show both your login and mdi forms from there.

How to add "sub main" to a vb.net windows application?

I think you've done this backwards. You can't close the form that your application started on without closing your Application. Make you startup form the MDIParent. When it starts, it needs to check to see if anyone has logged in successfully, if not, have it show the login form.
