Regex 4 Digits A Hyphen And 4 Digits?
Jul 2, 2010I'm trying to match a string to see if it matches exactly this:####-####, it has to be 4 digits followed by a hyphen followed by 4 more digits. Right now I have this pattern: "d{4}-d{4}" but it's allowing 5 digits in either (or both) instead of strictly 4 per group. Here's an example of what it should allow:
1999-2000
2003-2007
2009-2010
and here's what my pattern is allowing but should not be allowing:
20081-2009
2009-20101
12345-12345
12345-1234-1234

View 4 RepliesCreate A Program To Calculate Math Grade?
Feb 19, 2010I ma trying to create a program to calculate my math grade. The way my math teacher explained the grading scale was each test is worth 1 point and each quiz is worth .2 points.
So as an example (add both sides up then divide by both sides)
100 =1
80 = 1
15 = .2
18 = .2
213 divide by 2.4 which equals your grade of 88.75
There are more quizs and tests in the semester and I want the numbers to change with the number of quizs and tests entered. The only problem is I am not sure how to code it. I though I would use IF AND statements but I am not sure where to start.

Feb 18, 2011if 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

Creating A Program For Which Will Calculate The Time Taken For A User To Make A Number Keystrokes?
Feb 18, 2012I 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.
