I also read somewhere that I should use: System.Threading.Thread.Sleep(1000) to delay the process or something - not entirely sure why I would do this though.Although, the problem with my above code is that when the code behind page performs validation checks, it exits sub before executing my INSERT SQL code - so when it does this it also disables the button.I am not entirely sure if the above method is fool proof or whether it is a **** piece of code that won't work 100% of the time.On another website I found a script to put on the actual HTML page with <script> tags:

So, user presses button, second datagridview shows. Note that I don't want them to both display the same data - they should both be independetly editable..

I want to build it under option strict on first before I do anything else -- which maybe converting it into C#. I found there's thousands of lines of code raises compilation error, mostly are about implicit type casts. Is there any tool would help to make it compile under option strict on mode if I don't want to correct every single line manually? Because it's really painful to add CStr/CInt invocation into every line of Code myself.

I am working on a check digit program and I am having some trouble finding the best path to take. The program requires 5 digits (numbers). I am calling them
num1
num2
num3
num4
num5
My ultimate goal is to use this equation:
num5 = num1 + (num2 *2) + num3 + (num4*2) - but I use the second digit of the resulting number.
Example: number 12346 - would be "correct!"
12345 - would be "wrong!"
1 + (2*2=4) + 3 + (4*2=8) = 16 so the correct would be 12346 When the user puts in the numbers on the UI I will be returning a comment in a text box on the UI.Which direction should I start?
