This is a very common question. You should search the forum, which you should always do before posting.

Since you are using VS2008 try using a MaskedTextBox control. It should prevent the user from entering non-numerical characters (or any characters not matching the mask).

i can not use masked textbox control because it limits the number of digits

Well I don't have a lot of experience with MaskedTextBoxes, so I can't say if that problem can be solved... But I would advise you to consider using NumericUpDown controls since their return type is Decimal (I think).

How about using a NumericUpDown for this? It's not like it was made for this or anything.
