When I want to create a new panel at run time when I clicked a radio button it displays an exception at panel2.location.
Dim panel2 As Panel
Private Sub RadioButton5_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton5.CheckedChanged
panel2.Visible = True
panel2.Location = New Point(200, 300)
panel2.Size = New Size(200, 300)
Me.Controls.Add(panel2)
I am designing a simple user interface using winforms. In the designer I have a panel on the form and would like to add a datagridview control into the panel at runtime and set the dock property of the datagridview to 'Fill' so that it fills the panel.
I am struggling to do this and following code is not working out for me:
Dim MyDataGridview as New DataGridView()
MyDataGridView.Dock = DockStyle.Fill
Me.MyPanel.Controls.Add(MyDataGridview)
I don't get an error but the datagridview isn't visible. It gets added 'behind' the panel and so I tried using .SendToBack() and .BringToFront() methods thinking that the panel was hiding the datagridview but this doesn't seem to work either. At any rate, it seems like the datagridview is being added to the form but just not docked within the panel
I have a theater seating project. I am creating checkboxes in a panel that represent the seats. Each of the rows has a label on it, giving it a row number.When a user clicks one of the check boxes, I need to be able to determine what row the seat was that they clicked on. I then use the row number to determine the price of the seat. I am stumped!! I can't seem to figure out how to get the row number associated with the seat. Here is my where I am configuring the seats:
Private Sub ConfigureSeating()
intTheaterID = CInt(frmTheaterTickets.cboTheater.SelectedItem)
Dim strSQL As String

I'm in the process of converting a VB6.0 application to VB.Net (2008 Express). I have a MDI parent form, I'll call mdiBackground, and 4 MDI child forms, frmStatus, frmShow, frmQwerty, and frmSentence.The layout is as follows:mdibackground - has the menus at top and is a container for the child forms.frmSentence - appears at the top frmShow & frmQwerty - appear at the left and when one is closed the other one is in the same position.frmStatus - appears at the right, it has buttons which control when frmShow and frmQwerty are to appear I have a couple of regular forms that act as dialog forms. The Me.Close() works fine on these.

how to add controls in panel control runtime. I mean, I want to add group box at runtime. When I click on my button, it should add a group box in my panel and when I click again, it should move the first group box down and add the second. Every group box should have a label control in it.

The goal of this code is to add a control to a panel in runtime. This MUST be done in runtime for the purpose I intend. The problem is that, when I add a second control, the first one disappears.

Is there any way you can move a panel using the arrow keys during runtime?and is tehre a way of popping random objects in a game. Like you have this spaceship moving and your "Alien foes" or whatever attacks you. So you want them to pop up randomnly every few seconds or so. How?
View 10 RepliesI would like to resize a panel at runtime using a mouse.I only need Vertical resizing.So, I have panel1 and docked a label to the bottom of the panel, this will be the drag bar.Now I'm thinking I need to use the mousedown event and capture the Y coordinates of the mouse? On Mouse up set my panel height to those new coordinates?Also, I'm pretty sure my panel won't redraw itself when this is going on. Should I set the panel height while I'm dragging?

I wonder how you can make a picturebox selectable at runtime and also change the size and location during runtime?
Well I know how i can change the location of a picture box during runtime but that is only with a picturebox that is already defined in the form before runtime.
So I write an event for that particular Picturebox.
But now i want to do the same thing with a picturebox that a user can add during runtime and then the user should be able to select and move the picturebox.
So now i can't add code to the picturebox event so I wonder how you should do this. ( Maybe with reflection?)
And what if the user added 10 picture boxes and selects a certain picturebox. How do you make it possible that the picturebox the user clicks on is selected?
Should you store each picture box location on the Panel and then when the user clicks on a certain pixel in the panel where a certain picture box is it get's selected?
Exception is generated while adding owc11.chartspace to panel at runtime.

My project is a server/client application, how do I copy existing panel with labels and pictureboxes to show stats of clients connected? I mean once the server accepts a client, stats of that client is shown on a new panel but has the same contents as the existing panel. Any Idea how to do this? I was thinking to make a set of panels and hide them if there's no client connecting but what if there are too many clients connecting more than the set of panels already made?

Needing pointed in the right direction. I am fooling around with data sources and connections per homework and what I'm looking for is creating an SQL DB connection during runtime. I know that you can add a data source in design by going through the Wizard but what if one would want to create the connection, adapter, and dataset during runtime? Where would you start?
I have cruzed the net looking for some form of a tutorial to just get me started, I don't need it all completely outlined but I need to know where and how to start and what I need to declare the connection, string, and dataset as. I have seen a lot of information using VB6 but nothing that I come across seems to work.
My basic questions are:Do I have to create a seperate class for the database connection?How do I delcare the nuts and bolts of the connection,adapter, and dataset?If a seperate class isn't required then where is the most realistic place these items would be created?
