Sorry for the member part...didn't see it there Roll eyes | :rolleyes:

. But you should still lock the connection because I believe that 2 different objects try to use it. Maybe I am wrong but it wouldn't hurt to try.

You write something like this :

using System.Threading;
..............
Sign(...)
{
   lock(connection)
   {
        ----===Your insertion code===----
   }
}

You should also have the connection.Open() and connection.Close() in the same code block. Between 2 method calls there can be a lot of things happening. Smile | :)

I have two classes

public class class1
{
   public class1()
   {
   }
}

public class class2:class1
{
   public class2()
   {
   }
}

class2 inherits class1. So whenever an object is created for class2, will class1 constructor code work ?

Why don't you put some code in class1, set a breakpoint, and find out ?

I can't. because I am not in debugger user list. It's a restricted account.

You can't debug ? How is that possible ? How/why can it be locked ? I mean, where are you, that you're not allowed to debug ? That's just retarded.

BTW, you can do it with a message box then.

That's really funny thing. Our system admin thinks that whoever in the debugger list, they will misuse. So no access. Any way I managed with putting messagebox. Thanks.

Your system admin is a retard. How can you do your job, if you can't debug. I'd raise hell if it were me.

I'm also still amazed that it's possible to block you from debugging your code.

I have never heard that bevore.
But ok, the answere is "Yes" it will run the base constructor as well.
And it will be worked threw bevor the derived classes constructor
If you have a base constructor which takes parameters, you have to do it like this:

public baseclass(string text, int number)

public derivedclass(string text, int number, .....) : base(text, number)

All the best,

Hi All,

i am new to asp.net 2.0 please help me.

while enter special charecters in textbox how to validate this combination '&#' using regular expression pls help me in this .

Thanks And Regards,
Guru.

Put ValidateRequest="false" in the declaration at the top of your aspx. Now, your page will not block malicious script input, you need to do it yourself.

This is not the ASP.NET forum.

Hi,
Thanks for your answers for my previous post. It helped me solve my problem very quickly.Now I have one more problem. Frown | :(

Is there any built in vaildators available to validate inputs in windows application using C# (Like we have in asp.net development). If it is show please explain how to use it? or do I have to use regular expression to build validation?
Thank you.

You can use a maskedtextbox to do this, or use your own code.

Set the Mask property of the MaskedTextBox as per your requirement and the validaton on inputs will be done automatically. There are few predefined Mask available in the Visual Studio, you can chack if you can utilized any of them.

There is no support for lossless jpeg formats in C#, you need an external library in order to read/write/convert them.
