Forms :: Adding ListBox To A New TabPage During Run-time, Control Does Not Appear?
Feb 4, 2010
I have a tabgroup with 2 tabs. During runtime, I wish to add new ones. Though I can get the tabs added, I cannot seem to add the ListBox that is supposed to go with it.
In the code below, I added '*' to indicate a line I added to try and fix the problem, but (obviously) don't work.
Dim newTab As New TabPage("Group " + g.userLabel.ToString())
newTab.Name = "Tab" + g.userLabel.ToString
TabGroups.TabPages.Add(newTab)
[Code].....

I am having a bit of a problem adding an MSTSCLib.MsRdpClient7 control to a tabpage form.The code snippet at hand:
Dim t As TabPage = New TabPage
Dim rdpcount As Integer = 0
If Not rdp Is Nothing Then rdpcount = UBound(rdp)
Debug.Print("Current RDP count: " & rdpcount.ToString)
[code]....
This code bombs on that last line with the following error:
System.InvalidCastException was unhandled
Message="Unable to cast COM object of type 'MSTSCLib.MsRdpClient7Class' to class type 'System.Windows.Forms.Control'. Instances of types that represent COM components cannot be cast to types that do not represent COM components; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface."

I'm struggling how to set up MDI interface where I have a tabpage control on the parent form. Each individual tab page should act as a parent to multiple child forms but within a tabcontrol there is no IsMdiContainer property like on the form.Is it possible to set a tabcontrol to act as a parent?

I am using System.Windows.Forms.TabPage to store an entire TabPage for later use in My.Settings. Here is a brief description of the application.
I have a TabControl that has 3 tabs. One for user input, another tab for equipment settings, and then a final tab for Oven settings. On the user input tab, if the user de-selects the checkbox for Oven, the oven tab is saved to My.Settings and hidden.
I can then run the application without oven control. After running, lets say the user would like to re-run, this time with the oven. They go back to the input tab and re-select the Oven checkbox. However, the Oven tab doesn't re-appear. When stepping through the code, the is nothing stored in My.Settings for the oven tab page. Why not?
Also, I can open the application, and check, then uncheck the oven checkbox and the tab is hidden, then returns. I can do this all day. However, after running the tab will not return.

have another problem trying to solve again I am trying to add a line into a listbox in this format time item (10), so, e.g. 4:00 Item1(10) So when the next item is added into the listbox and so on, it will look something like this
4:00 Item1 (10)
4:10 Item2 (15)
4:25 Item3 (20)
The time is a Date, and the minutes to add on is extracted with regex. I was able to add the items like above with hardcoding but ain't successful when i try to do it in a shorter way.

And you choose your folder/path, then it shows the selected path in textbox.. We are succesful on this.. But now weve added a listbox, And when you selected the path it will do this..

i have a splitter control on tab 2, a grid and a scheduler control on tab 3..looks fine...i save it....close the form...reopen the form, and the controls are all resized and moved around on me....and not for the better.
wierd thing is that when i run the app, the controls are placed properly, but design time is totally f&*ked up.I know this one isn't me. is it the tab control? should i just do toggle buttons at the top and show/hide my own panels? this is just too freaky to deal with. is there an easy work around for this?

is there any way to populate a listbox with totals data from previous pages? I'm working on a project for a class where the final form needs to have all the totals from the previous 3 pages (each page has one total each), in some capacity (so I do not necessarily need to use a listbox if there is an easier way to do this).One thing about the previous 3 forms, two are set up in radiobuttons and one is set up w/a checkbox format (but I will likely change the radiobuttons over to checkboxes as a later revision).I just can't figure out how to populate the listbox with info from a previous form, I keep thinking load events, but that doesn't take into account which options might be taken from previous forms.once the totals from the previous forms have been added to the final form I will need to add a 7% sales tax. I assume that something such an if then statement will take care of that though.Just wanted to run that everyone here at the forum just in case there is a better way to do that.

I have created a user control that mimics what a label does. I realize I could have inherited the label control, but I am working on understanding the process. I wish to add items to the control. normally (in the code of my project) would do:
Form1.Label1.Controls.Add(mylabel)
After creating mylabel in the code of course.

I have designed a window application that: check the contents of a folder for specific files (HTML)move files to a 'working' diretoryparse each file with webbrowser control to extract datacall webservice to collect additional data
The main form has a large ListBox that displays event messages. What I want is for the application to display the messages as they happen. What seems to be happening is that the application will do everything and then display all of the event messages at once at the very end. pointers on how to write code that will add event messages to the ListBox as they happen?

I have an MDI application, say name of MDI is MDIParent. From form1 I am adding new tab pages to form2. In the first tab of form2 I have generated a ListView by calling a ListViewCreate() function in Load event of form2. I am not able to generate ListView for the new tabs. I tried calling the ListViewCreate() while adding newtab. But, it is not creating listview nor throwing any error.

Hello - I am using Visual Studio .net 2008. I have a form that has a tabpage control in it with 5 pages. I need to add another page, but in position 2, not at the end. Is this possible? I do not see any settings for the position of the page. Looks like I can only add one at the end.

I created a user control with a listbox in it and a public property ListItem()
Public Property ListItem() As String
Get
Return _ListItem
End Get
Set(ByVal value As String)
_ListItem = value
End Set
End Property
On FormLoad I wish to fill the Usercontrol Listbox with the values that the user supplies.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim u As New UserControl1()
u.ListItem = "hello"
u.ListBox1.Items.Add(u.ListItem)
End Sub
The Listbox does get filled.

I started programming in VB2008 couple of weeks ago (I'm using the express version) and I'm getting stumped by this ridiculously simple problem. I am trying to retrieve varying parameters from an external application and display their values in real time on a windows form control e.g. a label or text box. I already know what class and methods to reference for that, however I can only display instantaneous values (unless I use a .click event handler, but thats foolish I want them displayed without my intervention) I tried writing a loop in form load event handler but that prevents the form from loading. I also tried a loop in another module but that doesn't work either.

I'm a long-time developer but semi-new to Visual Studio .NET and VB.NET. I've been working on an application for months, written in Visual Basic .NET. It's a rewrite of a popular IDE of mine that's originally written in assembly. What I'm trying to do in VB.NET is have multiple TabPage classes that inherit from TabPage, ofcourse, but each having it's own methods for common functions like Cut, Copy, Paste, etc. so that when I call tab.Cut(), the TabPage class for the currently-selected tab is the one used. In each custom TabPage class, I'll have a New instance of the main control that goes in that tab.
I think there would be a problem when I loop through the TabPages since the Foreach routine can only use one object type, as far as I know (TabPage).Currently I have only one custom TabPage class called Page that obviously inherits from TabPage, has additional properties and also methods that allow editing functions for whatever control is selected to be displayed for the tab. For example, when I call the New constructor, I supply the editor type as a parameter: dim tab as New Page(HEX_EDITOR).I have edit controls such as text, syntax editor, hex editor, bitmap editor, HTML editor, HTML browser. This means I get a new instance of all of those controls each time a new Page is added to the TabControl. I'm currently disposing of the unneeded editors depending on which editor is the one needed. The scheme is not preferred but it works great for now as I work on other areas of the IDE.

I am using Visual Studio 2008 and recently a weird bug has appeared.In my forms I have a tab control with multiple tab pages. I can place a control on a tab page fine, but when I move it by way of clicking it and dragging it to another location, it leaves behind an outline of where it should be. Looking around, it has moved to the first tab page
