Hi there,
you need to use TabCount - 1 as the first index of the tabs is zero.
Alternatively, you can use this:
<br />
For Each t As TabPage In Me.TabControl1.TabPages<br />
taskID = t.Name.ToString()<br />
Next<br />
Hope this helps,
Daniel

Hi,
i have been playing with some code that creates Control array labels that display dates down in a column in a Windows Form, but i am having trouble with removing Control array labels if a date range changes.
How do i remove a Control Array Label? in the case where the quantity of labels required where to be reduced by the Control Form control selecting the start and end dates.
some of the code that i have been playing with is attached below.
************************************
************************************
' remove the day array. 'this part doesnt work in my case..
For pd As Integer = 0 To 12
Me.Controls.Remove(lblDayArray(pd))
Next
strDayRow = datAStartDate.ToString("dddd,dd MMMM")
'using the label DayArray create days in rows
For i As Integer = 0 To DayDiff
lblDayArray(i) = New Label
Me.Controls.Add(lblDayArray(i))
With lblDayArray(i)
.TextAlign = ContentAlignment.MiddleRight
.BorderStyle = BorderStyle.None
.Location = New Point(intDInitLocationX, intLocationY)
.Size = New Size(intDInitSizeL, intInitSizeH)
.Text = strDayRow
.Name = "lblDay(i)"
End With
intLocationY = intLocationY + intSpacingY 'increments to next day
datAStartDate = dpStartDateRange.Value
datAStartDate.AddDays(1)
Next

After finally getting somewhere with reading XML, I ran into a problem. I want to list all the feed titles in a listview, and then when I click on a title, I want to view the the "Description" tag corresponding to the selected item. What I am having trouble with is determining which item I have clicked so that I can display the corresponding description. Here is what I have now:
Private Sub ListView1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListView1.SelectedIndexChanged
Dim XMLDoc As XmlDocument
Dim NodeListTitle As XmlNodeList
Dim NodeListText As XmlNodeList
Dim XmlDocNode As XmlNode
XMLDoc = New XmlDocument()
XMLDoc.Load("C:\feed.xml")
NodeListTitle = XMLDoc.SelectNodes("/rss/channel/item/title")
NodeListText = XMLDoc.SelectNodes("/rss/channel/item/description")
'Determine what item is selected and display it's description
For Each XmlDocNode In NodeListText
PostBox.Text = XmlDocNode.InnerText
Next
End Sub
How should I go about getting the selected item and determining it's description tag? And is this the proper way to read an XML file? Thanks for the help!

How to calculate time difference in hours between two dates, let's say 01/01/01 12:00 and 02/02/07 7:00?
|
|
|
|
|
Just use the DateTime.Subtract function, like so:
Dim FirstDate As New DateTime(2007, 2, 2, 7, 0, 0)
Dim SecondDate As New DateTime(2001, 1, 1, 12, 0, 0)
Dim FinalDate As TimeSpan = FirstDate.Subtract(BDayNow)
Hope this helps!

You can subtract DateTime values, the result is a TimeSpan. You can use the TotalHours property to get the time difference. Example:
Dim startTime as DateTime = new DateTime(1, 1, 1, 12, 0, 0)<br />
Dim endTime as DateTime = new DateTime(7, 2, 2, 7, 0, 0)<br />
Dim diff as TimeSpan = endTime - startTime<br />
Dim hours as Double = diff.TotalHours;

Hi there,
You can use the 'DateDiff' function, realy easy to work with.

I heard on this forum that .NET 2.0 has an integrated capability to compress folders to zip file. How to use this and what is the syntax? Can you give me an example code? I would like to compress two folders "C:\temp" and "D:\foo" into a single zip-file that would be saved into "E:\zipfiles".

Hi,
I have two forms say Default.aspx and popup.aspx
Default.aspx cotains a textbox whereas popup.aspx contains a text area.
When user enters more than 10 characters in a textbox of default.aspx,popup.aspx should open and all characters of text box should get transfer to textarea of popup.aspx.
The code that i had written using javascript is as follows:
function limitText(){
var textboxvalue = document.getElementById("limitedtext").value;
if(textboxvalue.length == 10)
{
alert(textboxvalue);
window.open("popup.aspx?value=textboxvalue","","resizable=1,width=600,height=200")
}
}
And This is textbox code:
******Retrieving value in popup.aspx********
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Dim strQuery As String = ""
strQuery = Request.QueryString("value").ToString()
TextArea1.Value = strQuery
End Sub
But When i put break point and check the value of strQuery, it is showing
"textboxvalue" instead of characters typed in the textbox.
I will be very grateful if you tell me that how should i pass the value through the url from the line:
window.open("popup.aspx?value=textboxvalue","","resizable=1,width=600,height=200")
Thanks

This is an ASP.NET question.
Pass the data on the URL.

The only place you're going to find VB6 is on eBay. VB6 hasn't been available for purchase retail for about 5 years now.

Can anyone tell me what is the syntex to open a HTML file in my documents? (\My Documents\123.html)
When I click on the button, I want the HTML file appear.
What's wrong with the coding below?
Dim sr As StreamReader = New StreamReader("\My Documents\123.html")
Dim line As String
Do
line = sr.ReadLine()
Console.WriteLine(line)
Loop Until line Is Nothing
sr.Close()
Thanks for your help!

The main problem you would have here, is that you don't have a proper path to the file. You can use Environment.SpecialFolder to get the path to the current MyDocuments folder.

I don't think so because the html file is located at My Documents.
May I know how to use Environment.SpecialFolder?
Thanks for your reply!

My Documents maps into the users profile, like this:
C:\Documents and Settings\<userid>\My Documents

Sure, all you have to do is read the documentation[^] on it. It's very easy.

Like Dave said. I'll just add, if you want to be a developer, when someone tells you to use something you don't know about, try typing it into google before you ask.

I would like to acheve that when the user clicks on save form or tries to close the form,
the code would check if chkbox_otp is checked and if it is not checked than would show a msg to the user, that they must select a town from the combobox(listbox).
THANKS!!!

The form has a FormClosing event
Sub Form1_FormClosing(byval sender as Object, byval e as System.Windows.Forms.FormClosingEventArgs)
You can check here for your condition, if it doesn't meet your check
there are two parameters passed to this procedure.
Use the e FormClosingEventArgs
e.CancelReason="You Need to check that"
e.Cancel=True
Hope this helps.

Hi CodeDoctor!
Thank you for your reply.
When I click on the form I see:
Option Expilict. Below that: Privat Sub lblRefer_Click()
End Sub
Privat Sub Command1_Click()
End Sub
I have found this:
Privat Sub Form_Unload(Cancel As Integer)
---Should I put your code here maybe?---
End Sub
I don't have a Sub Form1.
I'm sorry, I am a beginner.Thanks So much!!
