A TabControl stores it's pages in a <a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.tabcontrol.tabpagecollection_methods.aspx">TabPageCollection</a>[<a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.tabcontrol.tabpagecollection_methods.aspx" target="_blank" title="New Window">^</a>]. You can add or remove pages from this collection.
Hope this helps

I'm sorry for wasting your time, but at the time it sounded like a viable alternative to me

Its Ok Dear
As there is no any "Enabled" property of tab page so we have to check it is in tabcontrol's "SelectedIndexChanged" event like the following code
Private Sub tabCon_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles tabCon.SelectedIndexChanged
If YourCondition Then
Me.tabCon.SelectedIndex = 1
End If
End Sub
to set defualt TabPage write the following code in form load event
Me.tabCon.SelectedIndex = 1 'Here 1 is the index of desired tabpage

You haven't said on which line the problem occurs. But, from the error message, you probably sent an incorrect argument to a method call somewhere. Without knowing on which line the error occured, it's pretty much impossible to tell you what went wrong.

Hi all
Can some one plz tel me what is the difference between textbox.text = "" and textbox.clear.
The same thing works for some some other controls also. ????
|
|
|
|
|
Basically both do the same task
We can blank a textbox control by assinging a blank string ie "" or by calling its Clear method
|
|
|
|
|
To make it worse, there's also
Textbox.Text = String.Empty Since it is a reference-type, you could even say
Textbox.Text = Nothing In programming there's seldom a single way or approach to do something

I'm trying to upload a file in VB.NET using an HtmlInputFile, but everytime I upload, the HtmlInputFile's PostedFile is Nothing.
Here is my ASP.NET code:
<form id="Form1" method="post" runat="server" enctype="multipart/form-data">
<asp:DataGrid id="dgTitles" runat="server" OnUpdateCommand="dgUpdate" DataKeyField="ID">
<Columns>
<asp:TemplateColumn HeaderText="Title" >
<ItemTemplate>
<asp:Label ID="lTitle" Runat="server">
<%# DataBinder.Eval(Container, "DataItem.Title" )%>
</asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="tTitle" Runat="server" text='<%# DataBinder.Eval(Container, "DataItem.Title" )%>'>
</asp:TextBox>
</EditItemTemplate>
</asp:TemplateColumn>
<asp:TemplateColumn HeaderText="Image">
<EditItemTemplate>
<input id='fuEditImage' type="file" name="fuEditImage" runat="server" enctype="multipart/form-data" />
</EditItemTemplate>
</asp:TemplateColumn
<asp:EditCommandColumn UpdateText="Update">
</asp:EditCommandColumn>
</Columns>
</asp:DataGrid>
</form>
Here is my VB.NET code:
Sub dgUpdate(ByVal sender As Object, ByVal e As DataGridCommandEventArgs)
Try
Dim Title = CType(e.Item.FindControl("tTitle"), TextBox).Text
Dim fuUpload As System.Web.UI.HtmlControls.HtmlInputFile = CType(e.Item.FindControl("fuEditImage"), _
System.Web.UI.HtmlControls.HtmlInputFile)
If Not fuUpload.PostedFile Is Nothing Then 'This always = false
If Not fuUpload.PostedFile.FileName = "" Then
UploadImage(fuUpload)
End If
End If
Catch ex As Exception
'Handle Exception here
End Try
End Sub
When I upload a file, fuUpload is not Nothing, but fuUpload.PostedFile is.
The inputted "Title" text is recognized no problem.
I've also tried with FileUpload object and tag, instead of input tag and HtmlInputFile-- same result.
Can anyone tell me what I'm doing wrong? Why is PostedFile always nothing?
Thanks!

This question should really be asked in the ASP.NET Fourm. It has nothing to do with VB.NET at all.

Hi All,
I have a requirement for a tool/application/website that can help us to audit the security groups that an owner owns in Active Directory. I need an application that can do the following:
1. List the groups an owner owns (we have a database that contains group name, ads path, owner information hence the code can be linked with the database to get the information)
2. Owner of a group could select the group and veiw the members of that group (May be the code needs to be linked with AD to get the members of the group)
3. Using the tool we should be able to send the email to all the members of a selected group or specific members of the group ( This is required for audit purpose. owner needs to check with the members of the group if they still needs access to the group or not hence need to send an email. As a group can have hundreds of members, sending a manual email to everyone is time consuming). The email should contain a link which can take the user probably to one of the interfaces of our tool- that we need to develop. It should ask the member- do you still need access to the group and have two choices- yes and No. If the user selects Yes and submits nothing should happen. If the member selects No and submits it , member should be automatically removed as a member of the group and the owner of the group should be notified about the change (through an email or something).
I am not sure which programming language or scripting can help me to achieve this application. Any help will be greatly appreciated. It would be great if someone can take it up for me. I can give you the information that you may need for this project. You can let me know your terms and conditions.......if both of us agree we can start working on it at the earliest.You can email me at luvsohail2000@yahoo.com
Thank you.

Hi,
I'm shuffling a deck of cards, but seem to keep getting more than one of the same card, after the shuffle. So, I tried quite a bit trying to set the value of the card to not equal the subnum of the card, but it didn't work. Any ideas would be much appreciated. Thanks. Here's part of the code:
Private Sub Start_Click()
Dim arrDeck(52)
Randomize
CardCount = 1
Do While CardCount < 53
arrDeck(CardCount) = -1
CardCount = CardCount + 1
Loop
CardCount = 1
Counter = 0
Do While CardCount < 53 And Counter < 53
3 CardVal = Int((52 * Rnd) + 1)
If arrDeck(CardVal) = -1 Then
arrDeck(CardVal) = CardCount
Subnum = Counter
Image1(Subnum) = Image1(CardVal)
Image1(Subnum).Visible = True
CardCount = CardCount + 1
Counter = Counter + 1
Else: GoTo 3
End If
Loop
End Sub
|

have you tried applying a number between 1 and 52 to each card, the as each number is picked randomly it is added to an array.
on the next random call, it is checked to the contents of the array, and if found to have been picked already is rejected.
It will slow doown as the cards are dealt, but then that array will be filled from 1 to 52 in random order, just apply the numbers back to the cards to give a random shuffle.

You can add your cards to a collection and then pull the cards from random positions out of that collection and add them to another collection.
Private Function GetShuffledDeck() as List(Of Integer)
Dim cards As New List(Of Integer)
For i As Integer = 0 To 51
cards.Add(i)
Next
Dim RNG As New Random()
Dim deck As New List(Of Integer)
While cards.Count > 0
Dim cardNum As Integer
cardNum = RNG.Next(0, cards.Count)
deck.Add(cards(cardNum))
cards.RemoveAt(cardNum)
End While
Return deck
End Function

Wow, thanks! This does make total sense, except I have one question which might be a "newbie type:" Cards.Add(i) would produce 0 -51 cards right? Then deck.Add(cards(cardNum" would produce a random ineger and remove at cardnum....since it is in the same function, then there is an end value of 52 right? It seems confusing to me on how the end value is represented in your shuffle procedure. Thanks very much for your time! You are AWESOME!
