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.

View 1 RepliesIm 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.
