I have a string in which the numbers are entered and decimal point is also allowed. But, when the user enters a string for eg: 123,43 .....even this should be accepted as number and with "," is assumed as period "." , how can i do this.

use Replace()

Nothing to do with trimming really, you want to look at String Replace[^]

NumericUpDown, with two decimal places. I would expect the current culture would determine which decimal delimiter is in use (though I've never tried it).

I trust it does, but the way I understood it the OP wanted both period and comma to act
as decimal point (which I fully understand, the lack of a single international standard way
of using periods and comma's is troublesome).
my point however was the up/down doesn't seem very useful for long numbers: when the increment
corresponds to the last digit, it takes forever to up/down the leading digits; and when it does not,
the last digit(s) are not affected by it.

Yes, but I tend to just type the number into the NumericUpDown anyway.

I see, I'm still use TextBoxes for that, with some masking if appropriate.
The NUD does a lot of masking (and limit checking) but seems to accept multiple decimal points,
so it may still need validation. And I wish there were a way to hide the up/down arrows...

Your subject line suggest you're trying to update the DataSource property of a DataGrid control from a background thread you created. If this is true, you cannot do that. You MUST Invoke a method on your form so the UI thread updates the control's DataSource. You cannot manipulate controls from any other thread other than the one that created the control.

You'll need to create your own control, deriving from the Control class. Override the OnPaint method in this, then use the Graphics object provided in it's PaintEventArgs argument to draw whatever you want. Hint: Graphics.FillPie might come in handy.

Doesn't really matter, UserControl allows you to use the visual designer, which you probably won't be needing in this case.

Hi All,
I am drawing rectangle on the form. (VC#)
I am able to resize the rectangle when rectangle is at zero degrees.
For example, if i want to resize top right:
rect.Y = mousepoint.Y;
rect.Height += OriginalRect.Top - mousepoint.Y;
rect.Width += mousepoint.X - OriginalRect.Right;
whereas 'rect' is rectangle after resize, 'mousepoint' is mouse pointer while mouse move.
But
When i rotate rectangle at, say 30 degrees, I have the problem, the above code won't work.
I need to change x, y, width and height. How to do it? I just want a clue.
I want to make sure that i am using Visual Studio 2005. This app is NOT WPF.
Thanks in advance.

Use the Rectangle's Inflate method.

What? You are doing your final year project, as in you have been in the class all year, and now you are doing your final project? And NOW you need to learn C#? Didn't pay attention in class huh?
