Hello,

If you want to show it as a string, you could use the String.Format method.

int numberofdecpoints= 10;
double d = 3765/3700 * 100;
string roundednumber =  String.Format("{0:F"+ numberofdecpoints.ToString() +"}",d);

All the best,

Martin

May not be the prettiest

double d = 101.75675675675675675675675675676;<br />
string s = string.Format("{0:f2}", d);<br />
d = Convert.ToDouble(s.Remove(s.Length-1));

Using the specifier {0:f1} still rounds the number to 101.8, so use 0:f2 and truncate it.

only two letters away from being an asset

Can't you just do this?

<br />
double d = 128.158676;<br />
Convert.ToDouble(Convert.ToInt32(d * 10)) / 10;<br />

double d = 101.75675675675675675675675675676;
d = Math.Floor(10 * d) / 10;

Now d has a value of 101.7
Hope this helps

There isn't one. It is a new feature of Visual Studio 2005.

For VS2003, you will need to use an external application such as Visio. The class designer was added in VS2005.

Class Diagram option is not available in Vs2003.

It is a new feature which is available in VS2005 only.

It sounds like you are attempting to write a keylogger. I don't think many people will want to help you with that endevour, unless you can give a legitimate reason for wanting to do this.

I can't think of a legitimate reason that you would want to do this. Kindly enlighten me as to what you are trying to do. Alternatively, hand yourself in at the nearest police stations because you are trying to write a keylogger which is a VERY BAD thing to do.

Putting roses in your text is not likely to get anybody here to help you become a hacker.

Yeah, I thought that was a really nice touch. However, he ought to learn that most people realise roses are usually quite thorny.

As other people have said, noone is going to help you until you've managed to convince us that you're not doing this for malicious reasons. "My boss said we need it" is not going to work.

Hi,
I believe that the column which is going to be validated is passed in the Event arguements. So you can have it in KeyDown/Validating etc events.
I dont have development environment setup to tell u exactly.

hi,
Thats the beauty of OOP, Create instances of Textbox class at runtime, give them Ids, text, set the desired location to be displayed on the form. Thats it!

Hello

I have a problem in MDI Form1 is the parent form Form2.
When i call the form2 like this:

frmChild=new FormChild();
frmChild.MdiParent=this;
frmChild.ShowDialog();

that give me an error "Forms that are not top level forms cannot be displayed as a modal dialog. Remove the form from any parent form before calling showDialog."

I want to open frmChild as a Modal Form so the ShowDialog() is necessary. how can i overcome this problem??

thanks

Once you've made a from an MDIChild of another form you can't use ShowDialog() on it. You have to show it using Show() method only. To use ShowDialog() is to make it modal -that means it takes over the focus from all other GUI elements and forms-, which is not supposed to be in an MDIChild form.
