View 10 RepliesI am creating a program for which will calculate the time taken for a user to make a number keystrokes. I want to start the timer running from the beginning of the first key stroke and end on the final keystroke. Each keystroke has been linked to a label which will change colour according to whether the key has been pressed. When the keystrokes have been finished I want to save this timespan in a field in a database. To test that the timer is running I have made a messagebox which will show the time taken however it is constantly showing zero and the label for the final keystroke is remaining in the keydown colour.

View 15 Replieshow to make a program that makes all the possible characters and numbers (A-Z & a-z & 0-9) from 5-20 characters, and put them in a list or something?
Someone may think this is bruteforce hacking, but I don't see why I should do that? If I want to find a password on 13 characters, it would be: 62^13 = 200028539268669788905472 possibilities... in other words... it would take forever!
Im trying to make a program that makes a user type in a password, then open a folder where the user can put files. but once they close out of the file browser. the program needs to save the files and remove the directory. for example think of a file cabinet being the program, and the drawer being the temp folder. when the user closes the drawer, it goes back into the cabinet, or in this case the program.

if you want to make program to calculate the result of brackets math question , as 6+(9+(5-(1+(2+1)))) , and you made 2 buttons representing ")" and "(" , and you want when the user clicks on the "(" button it just applies that the number before it to be stored in a place like a label such that the program calculates numbers after it and then calculate the produced number and the label number , something will disallow you that the questions with many brackets as the mentioned one above 6+(9+(5-(1+(2+1)))) will for example store 6 and plus sign in a label but after that 6 will be placed by 9 because there is another bracket after 9 , so the question will be calculated false , more clarification for my question is the way brackets are made in the windows calculator so i want a coding idea to make the brackets like in the windows calculator

Write a complete Visual Basic program to do the following: Joe's Pizza Palace needs an application to calculate the number of slicesa pizza of any size can be divided into.
The application should do the following:
Allow the user to enter the diameter of the pizza, in inches.
Calculate the number of slices that can be cut from a pizza that size.
Display a message that indicates the number of slices.
To calculate the number of slices that can be cut from the pizza, you must know these facts:
Each slice should have an area of 14.125 inches.
To calculate the number of slices, divide the area of the pizza by 14.125.
The area of the pizza is calculated with the formula: Area = π r2
Note: The π is pi which is equal to 3.14159.The r is the radius of the pizza. Divide the diameter
by 2 to get the radius.
Form:
The application should be done form-based. You may design your own form. It must have the following:
a label indicating that it is Joe's Pizza Palace
a field with label to enter the size (diameter) of the pizza
a field with label to display the number of slices
buttons to calculate the number of slices and to exit the application
Output:
Use the following test data to determine if the application is calculating properly:
Diameter of Pizza Number of Slices
22 inches 27
15 inches 13
12 inches 8
Requirements:
Name the project Pizza.
Be sure to include your name included in a comment

View 2 RepliesI am constructing a program, i am new to Visual Basic, but i have past programming experience. I was wondering if anyone knew how to form a loop that could...lets say calculate the answer when two numbers are added together,and it would repeat this thousands of times, etc. And if there is a way, would it be possible to calculate the time taken to complete this loop.
View 5 RepliesSo I wanted to make a program for math where you enter a number into a box. Then you click enter. The program has numbers 1-12 next to a check box. If you click enter it divides your number by the numbers 1-12. Let's say you put 100 in that box. Then you clicked enter. The check box next to ten would be checked, 4, 2, and 5 would all be checked because those numbers evenly go into 100. How can I have the vb check to see if the sum is a whole number?
