Validate Some Data From The User And Their Corresponding Value?
Dec 2, 2010I would like to kindly ask if there is a dictionary in vb.net?
I would like to validate some data from the user and their corresponding value.
e.g.
2 = ABC
6 = MNO
6 = MNO
7 = PQRS
8 = TUV
8 = TUV
3 = DEF
if the user had input the numeric data on textbox1, then the alpha phrase will show on textbox2.
What i want to run is that if i press the "execute" button, it will look for a word than can be create using these letters ( e.g COMPUTE )
Then it will display the word "COMPUTE" on textbox3.
Is there a function or method i could use to do that?

Application Displaying Sum Of All Integers Entered By User
Jun 21, 2010I Create an application that when a user enters a positive integer value in a input box(the default number is 10) when the OK button is clicked, the application should display a message box with the sum of all the integers form 1 through the value entered by the user. If the user enters a negative value, the application should display an error message. I believe I have to use a loop condition but I have no idea what to do.
EX: User enters 10 in the input box once OK button is pressed a message box pops up and says "The sum of the numbers 1 through 10 is 55". Use the following test data to determine if the application is calculating properly
VALUE SUM
5 15
10 55
20 210
100 5050

Reloading User Entered Data At First Run Logic
Aug 20, 2011Ok so I have designed a program to figure out commissions for phone sales at my company. Since the devices we sell and their associated prices change over time, I had to make that data within my program dynamic. I have a form within my program (frmprice) that has 160 textboxes - 80 for the devices and 80 for the associated prices. Now I hard coded the .text members with default values for our current stock of phones and prices.
I also added code so whenever that form with the phones and prices (frmprice) closes it saves any changes that have been made to either the phones or prices and when the form loads it overwrites the default data with any data that the user had entered at last run.
HERE is my logic problem. At the very first run the program is overwriting the default hard coded values with "" because no user data has ever been entered before. So when the form with the prices loads, it passes the user entered data from last run which is null because it has never run before. If I test to see if default value <> the user entered data before it executes the code to pass the user entered values it will always test to be true because the user entered data is null at first run. If I test to see if the default value is = to the user data it will always at first run test to be false because there is no user data yet.
HOWEVER once the user entered data is initialized (anytime after the first run) I need the program to pass the user data from the previous runs back in. Just NOT at the first run. Here is the code i am using: (in the code below the variables ending in "val" are the ones that are of the type string and are saved in the application settings) The frmprice_Load Event:
