My question is, what object is it that is used to trace user activities in Windows Forms Application. In ASP.NET we use the Session object.
manv
|
|
|
|
|
OK, let me ask this question, how do you avoid multiple logins in windows forms application.
manv
|
|
|
|
|
There is no equivelent object in Windows Forms. There is also no such thing as a login to a Windows Forms app unless you code in your own security system.

Hi, I've got a 2D array which I would like to sort into descending order according to the first column but keep the information in the 2nd column in the same row as the information in the first column no matter where the sort moves it to in the array. To explain more clearly:
Supposing I had this 2D array:
|5 1|
|6 2|
|3 3|
|8 4|
|2 5|
I want my bubble sort to be able to sort it into:
|8 4|
|6 2|
|5 1|
|3 3|
|2 5|
All the info I've found on bubble sorts has only been about 1D arrays. Any help or a nudge in the right direction would be really appreciated!
Thanks,
your
peter

Something like this:
Private Sub Sort2DArray(ByVal TwoD_Arr(,) As Double)
'
Dim Tmp_Arr(0, 1) As Double
Dim upperInd As Integer
Dim lowerInd As Integer
'
For upperInd = 0 To TwoD_Arr.GetLength(0) - 1
'
For lowerInd = (upperInd + 1) To TwoD_Arr.GetLength(0) - 1
'
If (TwoD_Arr(lowerInd, 0) > TwoD_Arr(upperInd, 0)) Then
'
Tmp_Arr(0, 0) = TwoD_Arr(lowerInd, 0)
Tmp_Arr(0, 1) = TwoD_Arr(lowerInd, 1)
'
TwoD_Arr(lowerInd, 0) = TwoD_Arr(upperInd, 0)
TwoD_Arr(lowerInd, 1) = TwoD_Arr(upperInd, 1)
'
TwoD_Arr(upperInd, 0) = Tmp_Arr(0, 0)
TwoD_Arr(upperInd, 1) = Tmp_Arr(0, 1)
End If
'
Next
'
Next
'
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim TwoD_Arr(,) As Double = {{5, 1}, {6, 2}, {3, 3}, {8, 4}, {2, 5}}
Dim i As Integer
Dim j As Integer
For i = 0 To TwoD_Arr.GetLength(0) - 1
Debug.WriteLine("UnSorted: " & TwoD_Arr(i, 0) & " " & TwoD_Arr(i, 1))
Next
Sort2DArray(TwoD_Arr)
For j = 0 To TwoD_Arr.GetLength(0) - 1
Debug.WriteLine("Sorted: " & TwoD_Arr(j, 0) & " " & TwoD_Arr(j, 1))
Next
End Sub
Returns:
UnSorted: 5 1
UnSorted: 6 2
UnSorted: 3 3
UnSorted: 8 4
UnSorted: 2 5
Sorted: 8 4
Sorted: 6 2
Sorted: 5 1
Sorted: 3 3
Sorted: 2 5
Hope that helps,

Visual Basic 2005 Professional Edition:
I need to drag and drop an image from one PictureBox to another PictureBox where:
1) the image is visible while being dragged
2) the image can be dropped at any location within the target PictureBox
3) the image can be rotated within the target PictureBox

jo0ls at xtremevbtalk.com wrote a program that does it all!
1) Transparent backround on dragged objects.
2) See object as it is being dragged.
3) Rotate object.
4) Nudge object.
5) Delete object.
6) Drag multiple objects.
7) Drag multiple copies of an object.
8) Redrag objects.
9) Drag objects of any size
Wow!

I want to make changes to the HTMLdocument that resides in a WebBrowser.Document
I can navigate to a web page,
WebBrowser1.Navigate(address)<br />
and the image looks good in WebBrowser1. After the document completes, I capture the event when a page element is clicked on:
Dim ClickedElement As HtmlElement<br />
Private Sub Document_Click(ByVal sender As Object, ByVal e As HtmlElementEventArgs)<br />
If (WebBrowser1.Document IsNot Nothing) Then<br />
Dim pt As Point = System.Windows.Forms.Cursor.Position<br />
pt = PointToClient(pt)<br />
pt.Offset(-WebBrowser1.Left, -WebBrowser1.Top)<br />
ClickedElement = WebBrowser1.Document.GetElementFromPoint(pt) 'WebBrowser1.Document.Window.Position)<br />
ClickedElement.ScrollIntoView(True)<br />
tblElements.Rows.Clear()<br />
AddElementToTable(ClickedElement, 0, Direction.Ascending)<br />
DataGridView1.DataSource = tblElements<br />
End If<br />
End Sub
Now I can do either of these:
'Change the ID of an element<br />
If clickedElementID = "" then ClickedElement.ID = "t_19"<br />
or
<br />
'Add a new element after the one that was clicked<br />
Dim newID As String = ClickedElement.Id & "_t1"<br />
Dim newElement As HtmlElement = WebBrowser1.Document.CreateElement(newID)<br />
newElement.Id = newID<br />
ClickedElement.InsertAdjacentElement(HtmlElementInsertionOrientation.AfterEnd, newElement)
Both of these changes show up if I check the element:
For Each el As HtmlElement In ClickedElement.Parent.Children<br />
Console.WriteLine("Sibling id: " & el.Id)<br />
Next
Sibling id: t_19
Sibling id: t_19_t1
But I can't figure out how to have the display reflect the change or how to save the UPDATED version of the html. The WebBrowser1.documenttext doesn't reflect any changes.
Thanks!

Check with your system administrator whether you have an appropriate permission to write (save) to your file.

Does anyone have a good example of a TCP/IP server using the TCPListener and TCPClient classes in VB.Net 2005?
I need to write an application that listens for TCP/IP client connections. Once a client is connected the server must maintain these connections in order to process any incoming commands and to send out status information to the clients.
Any help would be appreciated.

How do I setup project written in vb.net 2003, so application could be ran from the network drive?
David Pudel

First you copy/install the application files onto the network drive.
Next, you must install all of your app's dependencies on to each client system that will run your app. This includes the .NET framework, MDAC (if you're using ADO.NET), any ActiveX or COM objects used, etc. If there are a lot of dependencies, then you might want to write a "Client Installer" for your app to simplify the process for your users.
