Thanks Briga, dotnethead, and Steve for your replies.
As suggested by briga, i ran a test program with loop of 9999999. When i run the test about many times, each time the result was different. Some times Case #1,#2,#3 all took same time, at times #1 was the fastest, at times #2 , another time #3 and at other times there was a tie b/w the cases. so could not reach a conclusion.
As Steve pointed out [it was the reason i posted the question] #1 involves an implicit type conversion [integer is converted to boolean], #2 a comparison and #3 an explicit type conversion, it is difficult to say which would run faster.
After much thought i too reached the conclusion that #2 is better [it atleast explains the code better]
Thanks every one

Microsoft has a speech SDK. If it work with .NET, you can use any .NET language with it.

Hi All,
In my project, I want to check the version of Oracle SQL*PLUS used. The user will browse for the Oracle SQL*PLUS executable and give the path together with exe name in a text box. But if there are two SQL*PLUS exes installed in the machine (One with version 8 and the other with version 9), I want to check the version of the SQL*PLUS executable. Only the executable with version 9 will be working for my project. The confusion is that there are two types of SQL*PLUS available for each version. One is a windows based utility with name SQLPLUSW.exe [Oracle Version 9] and PLUS80W.exe [Oracle Version 8]. The other is a Dos utility with name SQLPLUS.exe [Oracle Version 9] and PLUS80.exe [Oracle version 8]. My problem is I am not getting the version of the Dos utilities (PLUS80.exe and SQLPLUS.exe) using the GetFileInfo() method.
Can anyone suggest a method to get the version of a DOS-based utility program?
Thanks in Advance

DOS .EXE's don't have this kind of metadata in them. About the closest you're going to get is probably checking the file's date/time stamps or file sizes for the correct version. Or, possibly looking for some kind of signature in the .EXE file somewhere. You'd have to know what the differences are between the two versions of the same file, though.

Dear All,
1. Develop by VB.NET 2003
2. Using MS-Access database
3. When execute in Windows NT 4.0 Server, pop up me an error message say "Microsoft.Jet.OLEDB.4.0 provider is not registered on the local machine".
Who can tell me what's wrong in Windows NT 4.0 Server.

Install MDAC if it is not installed. If it is installed try reinstalling it.
If that doesn't help try installing Jet 4.0 Service Pack 8.
You can also use the Component Checker to find problems with your MDAC installation.

Thank you. I was try myself to install Microsoft Jet 4.0 driver on it. Now can work already.

Hi,
I am not quite sure if "Is it possible to create a reversible hash?" is the right question here but this is what I am trying to accomplish....
I have certain strings that I would like to convert to somthing unreadable and back to the original text. The key is not only to make the string unreadable but to make it as short as possible as well.
I tried using .NET Cryptography but I cannot convert the hash back to the original string.
Does anyone know how to accomplish this?
Thanks,
Zenly

A hash by definition cannot be converted back to the original string. Making it short means you throw away information that cannot be retrieved.

Well, you can use a regular expression to check, or you can create an input control that only accepts those characters.

Assuming none of the ones you'd find with google can help you...
Basically you derive a class from the input control, and handle the key press events. Use Char.IsLetterOrDigit to check if a key press is what you want, if it's not, then set the Handled property to true and the base method will not be called, therefore the key press will not be accepted.

how can i check my network is connected, pleaae help me, thanks

Hi!
You can use the sensapi.dll of the internet explorer to check if the network is been connected:
Private Declare Function IsNetworkAlive Lib "SENSAPI.DLL" (ByRef lpdwFlags As Long) As Long
This is the API declaration to access the IsNetworkAlive function within the sensapi.dll.
So, just use it like this:
Dim llReturn as Long
IF IsNetworkAlive(llReturn) = 0 THEN
' Not connected code
ELSE
' ... Your code (if connected)
End If
If you need more help, just let me know!

Hi!
Here an other example:
<br />
Private Declare Function IsNetworkAlive Lib "SENSAPI.DLL" (ByRef lpdwFlags As Long) As Long<br />
<br />
Private Const NETWORK_ALIVE_LAN = &H1 ' LAN connection<br />
Private Const NETWORK_ALIVE_WAN = &H2 ' RAS connection(for internet)<br />
<br />
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click<br />
Dim llReturn As Long<br />
<br />
If IsNetworkAlive(llReturn) = 0 Then<br />
MessageBox.Show("Your system is not connected!")<br />
Else<br />
If (llReturn And NETWORK_ALIVE_LAN) = NETWORK_ALIVE_LAN Then<br />
MessageBox.Show("Your system is connected to the LAN" + _<br />
" (may be over router to internet too)!")<br />
End If<br />
If (llReturn And NETWORK_ALIVE_WAN) = NETWORK_ALIVE_WAN Then<br />
MessageBox.Show("Your system is connected to the WAN by any" + _<br />
" kind of modem direct connected to you system!")<br />
End If<br />
End If<br />
End Sub<br />
If you need more help, just let me know!
