Design an algorithm to validate and store

[bseos]

Im new to VB and i have been reading alot into it.

I have come across 4 problems in which i have had trouble completing.
I have little idea of what is required but i dont know how to do it.

1) Design an algorithm to validate the data controls on the form and store the values into the appropriate variables converting the data type if necessary.

2) Design sample data sets that will test your algorithm and carry out a desk check.

3) When the algorithm checks out OK design VB code to implement the algorithm.

4) Add your code to the existing project code and test using the same data used to test the algorithm.

I will post what i have done but i need help with writing the algorithm. If anyone can help me i woul dreally appreciate it and will be very grateful for your help. Iv tried asking friends but they have no clue of coding. Please.
