Yes, interesting idea (I'm assuming you mean combine all of the 2000 individual files into one single dataset)
One problem is that the resulting dataset is huge.
Here is the issue:
The textfiles are about 25K each times 2000 files = 50,000. Not a problem
Turn each of those textfiles into a datatable, each datatable is now 200KB!
200 * 2000 = 40M
OK that can be done, but seems really wasteful, and takes a long time to read it.
So really I'm looking for an alternative that doesn't require datatables at all. Until I get an alternative, I'm tempted to just say with the textfiles themselves.
BTW object arrays serialize to a size that's somewhat bigger than the original textfiles, but not much (about 37K each)

How can I put code on the close[x] button of the messagebox?
|
|
|
|
|
MessageBox.Show() returns a DialogResult value, which depends on how it got closed.
There is a value for each possible Button, and IIRC the Cancel value is also returned
when the Close Box is clicked (check it!).

You can't. However, you could always create a custom messagebox control.

Hi All,
I want to create a Wi-Fi Monitoring and Detection System using .Net 2.0.
1. It will detect any wireless computer coming in the range of access point….
2. It will then authenticate the detected ones by assigning them network parameters
3. It will then monitor the wireless computers by using SNMP protocol
Is there sdk present for that or any API available in .net. I have worked LAN Monitoring System, but i don't know how to monitor Wi- Fi devices.
Can anyone please help me out?
Thanx in advance.

That ALMOST sounds illegal. May I ask what you are monitoring? Please don't lie and say something like your kid or for just for the sake of knowledge. It really sounds like your trying to steal sensitive material ie. credit card#, s.s., ect. But you may have a totaly valid explanation for wanting to know that kind of code and I would like to hear it.

Almost the same...
use 3 apostrophies in a row - these are the comment markers in VB- '''
The rest will become evident.

In VB.NET for making statement a Comment you use '. If you are talking about to generate NDoc Documentation then you can install "VBCommenter" available at gotdotnet.com which is an add-in for Visual Studio .NET which can generate XML like comments but with ''' and can also generate NDoc file to generate MSDN like documentation.
Hope it helps !

How to link webservice (Server) to connect to PDA (Client)?
any source code? thanks
|
|
|
|

The concept is the same as using a webservice from a standard windows application, except that you will have to create a "Pocket PC" project to code the client.
What you have to do is to:
1. Create a Pocket PC Application Project.
2. Add a reference to the webservice you want to use.
3. Take advantage of the functions and routines available through that webservice.
A sample call for the client would be:
Imports Application1.WebService1
Public Class Form1
Private WebService1 As New WebService1.ClassName
Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
Dim resultAdd As Double = WebService1.AddNumbers(txtNum1.Text, txtNum2.Text)
lblResult.Text = resultAdd
End Sub
End Class

I am in the process of writing a Button Bar control. The control inherits from the Windows.Forms.Panel but I only want to allow a Button to be added to control collection.
To achieve this I have written a ButtonCollection Class that inherits from Windows.Forms.Control.ControlCollection and shadowed the necessary method and properties to accept and return Buttons.
To the Button Bar class I have added a read only Property called Buttons that returns the ButtonCollection.
The problem I am currently having, is that when I now add a Button in design mode, using the Button property, I get the error message "'Child' is not a child of this parent"
This error is caused when the Paint event of the control fires :-
Private Sub ButtonBar_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint<br />
Me.Controls.Clear()<br />
For Each oButton As Infragistics.Win.Misc.UltraButton In Buttons.List<br />
Me.Controls.Add(oButton)<br />
Next<br />
End Sub
Any help here, greatly appreciated.
Thanks
Steve Jowett

Walaikum-Asalaam!
You can use ConfigrationManager's OpenExeConfiguration Method which returns a Configuration object use this object to manipulate your configuration file. As it is a shared Member you can access it without instantiating the ConfigrationManger Class.
For Example:
Dim Config as System.Configration.Configration = ConfigrationManager.OpenExeConfiguration(ConfigurationUserLevel.None)
Hope it helps !

Your button just needs to handle the appropriate events and change it's image
