Controlling Multiple GroupBox Items?
Apr 6, 2009
I was wondering if there is some type of code that could control mutiple textboxes in multiple Groupboxes, basically what I want to do is be able to trigger all the textboxes in each of the groupboxes to become non visible based off of a choice in a combobox...here is what I have so far but i'm still way off
Private Sub Combo1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs Handles Combo1.SelectedIndexChanged.

i have a sort of problem when i try to add some linklabels in my groupbox. I used this
Me.Controls.Add(Groupbox3)
Groupbox3.Controls.Add(FlowLayoutPanel)
I can only add 4 linklabels no matter how big is the groupbox, i tried autoscroll but nothing. How can i do to store minimum 20 linklabels in a groupbox? Here is the whole code i used:
Imports System.Net
Imports DevComponents.DotNetBar.Controls
Imports System.Windows.Forms[code]....
Is there any way, maybe with a specific reference to put a control that records what plays wmp activex and to save somewhere on your computer?

When I use My.Computer.Network.DownloadFile this will sometimes start downloading two copies of the file simultaneously. I wonder if there is a code to check whether there are more than one file being download at a moment, and if there is a code to cancel some of the downloads.

I am playing with VB 2008 using .Net 2.0 as the target to compile to and am trying to figure out if it is possible to create multiple countdown timers one in each form using a single timer.I have attemtped but the logic escapes me. If this is not possible I know how to use a timer on one form for that form.

Is there a way to write a single function that will control validating the input to any textbox? How to pass control of it.
E.g.: My second try was to:
Dim CurrentTextBox As TextBox << Declare a global
Write a function that uses the global textbox and takes in 2 parameters, one determining the length it has to validate and the second telling it what to do once the input is verified
Public Sub ConfirmInput(length As Integer, which As Integer)
If (CurrentTextBox.TextLength < length) Then
CurrentTextBox.BackColor = vbRed
GoTo DONE
ElseIf (CurrentTextBox.TextLength > length) Then
CurrentTextBox.BackColor = vbRed
[Code] .....
My first try was to pass a textBox parameter to the ConfirmInput function but I believe that's the same problem as above.

Here using VB .Net 2008. I seem to be having trouble getting group boxes to appear when I click a radio button.
For example:
CODE:
This indeed brings up the first radio button however I have other groupboxes underneath which with the same code will not appear when the radio button is checked.
Eg:
CODE:
The second groupbox does not appear and is directly behind the first groupbox. The Top code doesn't seem to be working either.

I have not programmed since the late 90's (VB 6.0)Using Visual Basic 2008 Express, I'm creating a simple program but have one question:Is there a quick way to change a value on multiple items? For my program, I need to make a group of text boxes (anywhere from 14 to 546 unique boxes) "Enabled = True" or "Enabled = False" depending on a user selected value.
In a little more detail: The user selects the number of data rows on one tab. On the other tab are 40 rows of text boxes (14 boxes per row). If the user selected 15 rows, every row below 15 should be "Enabled = False".Thus far, I've coded a bunch of if-thens that run each time the user changes the selected rows (a line for each text box that makes it enabled or not). There are then 40 if-thens with lots of code in each.
I am sure there is an easier way to accomplish my goal without using hundreds of lined-up text boxes.

I would like to disable a specific items from DropDownList. I have below code but it does not working. DropDownList have 5 items.And,I'm getting error:Index was out of range. Must be non-negative and less than the size of the collection.Parameter name: index
Protected Sub CheckBox1_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
Dim X As Integer = 0 <> 1
DropDownList1.Items(X).Enabled = False
End Sub
But, if I add a different value for X, then it disable 1st and 2nd item.
Protected Sub CheckBox1_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
Dim X As Integer = 0 or 1
DropDownList1.Items(X).Enabled = False
End Sub
My goal is if I would have a 365 items in DropwDownList to disable items for example between 120 and 150.

I am creating a web application in ASP.net/VB.NET and I have an issue with the gridview.Currently, I have the gridview populated with data from the DB and I've also coded the update button to allow the user edit any necessary information through a form that pops up.[URL]...
What I'd like to do, if possible, is add a button to the two right columns(I already put one in the Dock Out Time column) which will be invisible if the column is set or will set the current time to the column. Setting the time for those two columns is already handled through the update form, but my supervisor asked me to try and see if this was possible.
Those two Time columns are Templatefields(since I format the display time from what is actually in the DB) and I added an asp button in the ItemTemplate for that Set Button in the picture.Is this even possible to do and if so, how would I access this button in the code behind so I can add functionality(setting the time and hiding it if the column is not null)If it's not really possible to have two items like this in a templatefield I can just make 2 extra columns for these buttons but I think this would look much cleaner.

I have some items in my listbox which I will store everyone of them into my database, what I am doing now is looping the box and call my database saving logic to save every single item. I thought this is pretty inefficient, is there anyway that I can use to batch save my items so that I don't open and close the connection as many times as my items.
For Each item In outletToBox.Items
.CamCode = Items.ToString
.CamCampaignAutoID = retID
.CamRemarks = uitxtCamRemarks.Text.Trim
'---use savetable object to save to database table---

I have a number of idential repeaters, and I need to iterate through all of the items. I currently have:
For Each item In rpt1.Items
.do some stuff
Next[code]....
Is there a simple way to reduce this to a single For Each ... Next loop?
Edit: There are a number of local vars involved in "do some stuff", which is why I can't just pass the item into a function - the call would have to include about 8 ByRef params.
