Hello,
At the .Net Frameworks > 1.1, decimal.TryParse would be possible, or in 1.1 the double class has a TryParse method.
So there would be no need of a try/catch!
All the best,

What experience do you have with O/R mapper in .NET?
I need to choose one for use in my company
Which one is the best for you?
I have seen lots of positive feedback about this one:
LLBLGen Pro
What do you thing about this? Is it good or can I find better alternative?

You can also look into NHibernate[^]. There are quite a few codegenerators out there that make setting up a basic solution with NHibernate a breeze

We're developing a large distributed system for an oilcompany and we're using nHibernate. Works like a charm. I'm not working on the Data access layer myself, but the little I've seen so far has been great.

I'm rather partial to DevExpress Xpress Persistent Objects at http://www.devexpress.com/Products/NET/Libraries/XPO/Index.xml[^]. Have a look at it - it's seriously good.

How to find the square root of some number.
In PASCAL it was sqrt(n), but in C# i don't know.

Math.Sqrt[^]
The Math class has many wonderful helper methods in it. Recommend that you check it out if your application will be doing heavy number crunching.

Hi All
The problem is this that im setting these 4 properties from my application via comboboxes
[ 1 COM Port
2 Baud Rate
3 Parity
4 SopBits }
when the user selects the values from the combo boxes i want the value is also saved in the system as a default value
for example if one selects baud rate 9600 from the combo box so at the same time the system baud rate is also changed to 9600 same as if i change other values it is saved to the system
Could any on help me

I guess you're using 'system' to mean 'Application'. If the hypothesis is correct then see MSDN for <a href="http://msdn2.microsoft.com/en-us/library/k4s6c3a0.aspx">Application Settings Overview</a>.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

You might consider rewriting the boot.ini file.
There is an option there: /BAUDRATE. Use /BAUDRATE=9600 or whatever value has been selected by the user.

Is there a way to trim every character after a certian character. For instance i have a string like "12345.6789" is there a way to trim everything after the "." to show "12345"?
Thanks in advanced

This is the C# forum. I would suspect that the original poster is asking about how to do this in C#

As he asked in the C# forum, my bet is that he isn't.

Yes, Use IndexOf to find where the character is. And SubString to extract part of the string.

Strictly speaking if you were to trim everything after the "." the result would be "12345."

//you can write following code to the any button event, run it after finished //enter the keys
TextBox1.Text = TextBox1.Text.Remove(TextBox1.Text.IndexOf('.'));

Try this the textBox1.Text will have the input string and the Result is available in the sResult. Messagebox will display all the string trimmed to the left of '.'
string s = textBox1.Text;
char [] carrSplit = new char[]{'.'} ;
string [] sResult = s.Split(carrSplit);
for(int i=0;i
