I have a problem in putting the telephone number using the datagridview. I have build 2 forms which is form1 and form2. In the form1 there are 2 textbox and a 'To' button whereas in the form2, there is a datagridview which display the telephones numbers and a button. When run the application, the user need to get the telephone numbers from the database so that is why when clicked on the 'To' button, it will go to the form2 which is the datagridview. After selecting the telephone numbers and click on the button at the form2, the telephone numbers will be display at the form1 first textbox. But the problem is that, I grab the telephone number which has been display in the form1 first textbox to the second textbox in the form1. I could not get the telephone numbers.

I have a textbox which controls the interval of a Timer control. How do I filter out letters? Is it possible to restrict entry to numbers only (like if you enter a letter or a space, nothing happens)? Is there a property of the textbox that can accomplish this?

I want to validate a string in a textbox after a period.Lets say that it needs to be ".rad" (whatever). When I enter "radjesh.rad" and press "OK" it should check if the last 4/5/6 (whatever) characters (including period) are in the string. If I'd enter "radjesh" it should fail, but if I'd enter (e.g.) "radjesh.jrkrk" it should work.

Function StripPhone(ByVal sPhone as String) as String
Dim i as Integer

Im trying to do a lab that will obtain 10 numbers from the user using an InputBox() function, store them internally in a one-dimensional array, and then compute the average of the numbers and sort them in reverse numerical order. The program should control that 10 numbers (no more, no less) are entered, and that the numbers are fully validated as integers.
If the user enters non-numeric data, then an appropriate error message should be shown, and that number should be allowed to be re-entered as a valid number. Then all the numbers should be shown as a list in a 'message box'. So far I can get everything but the message box to show the list of numbers entered.

I declared a form variable;'declare a variable to see if at least 1 phone number has been entered Dim count As Integer = 0..In the text changed event I do this;[code]But when I add a breakpoint as soon as I run the app it says count is 1 on the first phonenumber. What is the error in my logic. Somehow I need to be able to tab through all 4 controls and if they are all empty then let the user know they need to enter at least 1 phone number.
