I have no solution regarding your question, but some annotations to your code snippet.
1. You don't need to call ToString for the Text property as it already returns a string.
2. Put the call to Parse into a try block to catch exceptions if your textbox displayed no valid numeric string.

Use the decimal data type. It's a 128 bit number with 28-29 significant digits.

Hi,
I am working on an Exam Application , I wonder if there is an easy way to
display mathematical expressions in VS.NET (C#). Calculation part is not
important.Main problem is displaying expressions same as in the real world.
for example
5+7
----- -> if its in the square root?
5+2
is richTextBox enough?
any articles , suggestion or solution from you , I would be glad...
Thanks...

I think most applications that does that, uses special fonts. I suggest you look for some, and then perhaps try manually painting it. Shouldnt be too hard

bascially,
we are looking for a method
to find out when a new mail arrives,
when it arrives and is from a certain sender,
we then want to detach the file attachment
and use the detachment in our application

Hello,
I am creating an application. But now i have added a login form, which i want now to be the new startup form.
I am not sure how to change the startup form. I have tried going through all the properties, but can't seem to change it to the new login form.
Many thanks in advance
Steve

Could it be that you're more of a VB-person? 
Ok, seriously, in C# a Windows Forms application is usually run by instantiating a form (can be anything, no special properties required) and feeding this form into Application.Run().
This is done in a static class member called Main, also in an arbitrary class.
If you have several classes with a static Main method then you'll have to tell VS.NET which one to use.
So you just have to find the Main() method in your project, where you'll find somethng like:
Application.Run(new Form1());and change it to
Application.Run(new NewLoginForm());(or whatever the name of your login form class is).

As you said, we can write down the following code:
namespace somenamespace
{
public class form1()
{
...
static void Main()
{
Application.Run(new form2());
}
}
}
So, can I take the Main() method as an independent entrance in the form?

This one is simple enough, for something like this, you DON'T change the start up form. Your main form should call the login form to get it's authentication information before showing itself.

Thanks for you help,
I am new to C#, but l think VB is much more simple at doing this.

No, not really. THe two languages are closely related and they both use the same classes and compile to the same IL. It only seems more easy because you're more familiar with VB...

sorry.
In fact, I mean how to implement a registration key or serial no for a shareware.
Regardless, thank you!

Hello,
Does anyone have an example of using the RASDial or RASApi32.DLL with C#? I am looking to be able to create a VPN connection programatically from within an automation application. I need to be able to establish a VPN connection nightly and download a file from a server. I have found a VB6 example of using RASApi32.DLL and launching the DUN for the VPN configuration, but would rather work with C#.
Thanks
