What my program does is load a file (password list), then progressively reads each line of text in the file whilst writing each line to a new file. After X amount of lines have been written, it should start writing the lines of text to a new document until the initial password list has been split into X amount of password lists. The problem I have is that after hours of tweaking, all I can get it to do is write either blank ocuments, or write all of the lines to only one file. I really need it to be able to split into multiple files, preferably at runtime rather than loading a whole text document into the program in a textbox or array then writing it to new files.Below is the source:

I have many textboxes that I need to have display percentages. I have used a masked textbox extender and the percentages display fine. using 99.99% as a mask and number as the mask type.Now my problem is that i want it to be converted to a decimal when i save it to the database e.g 50% saves as 0.5 and then when it comes back from the database it must display as 50% again. This is needed for numerous calculations. IS there a way to do this?

I am trying to make a program that can calculate the percentage of people passing an exam. There are buttons for each letter grade, and working label counters for each time you press a button. Each button looks like this, except replace the letter with the appropriate one.
Private Sub btnA_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnA.Click
Static intA As Integer = 0
intA = intA + 1
lblA.Text = intA
lblPercent.Text = (lblA.Text + lblB.Text + lblC.Text + lblD.Text) / (lblA.Text + lblB.Text + lblC.Text + lblD.Text + lblF.Text)
End Sub
My problem is that the percent does not equal what I get when I put the exact same numbers into a calculator.
The application I want to make is what I would call quite simple, you will have two text boxes where you enter in two team names.
i.e.
Team 1 v Team 2
Then below a little search button. And then when you click the button it will show a percentage of whom is most likely to win. Now I know that I would have to most likely enter something like
Team 1 v Team 2 WIN Team 1
Team 1 v Team 3 LOSS Team 1
Team 1 v Team 4 WIN Team 1
In some kind of script for this to work so when you search for
TEAM 1 v Team 2 it will show WIN Team 1

Like I said up top, it was easy to figure out how to add an additional 6 to the text in the textbox for CET_Hr.Text, and even display if it's AM or PM, ... So okay, that's that, now when it goes over 12PM and goes into Am, meaning, when I'm adding 6 to the text, If I didn't correct it, it would say... Say for example if it were 11PM now, EST, and I added 6, it would read, CET_ Hr.Text = 16 right, ... So how do I tell the program or the text in the textbox, that it't the next day... or better yet, when we get to the end of this month, 12.31.2009, and it becomes 01.01.2010 in CET, how do I do that, because I'm just so freakin perplexed about that it's crazy... Should I just give up, and just have a clock that tells me that it's 6 more hours then the bottom text boxes...?
I have a textfile with timestamps and the amount of minutes my machine has run.
To keep the size of the file in check, I would like to delete the first half of the text file, once the textfile exceeds 1 MB... I have a check in place to determine the file size.
What is the best way to go about deleting the first half of my textfile log?
Do you recommend storing the second half in a temp file, and transfering it to the original log?
Is there a simple way to remove the first few lines of a textfile?

Heres the problem. The company has instituted a bonus program to give its employees an incentive to sell more. For every dollar the store makes in a four-week period, the employees receive 2 percent of sales. The amount of bonus each employee receives is based upon the percentage of hours he or she worked during the bonus period (a total of 160 hours). The Calculate button will determine the bonus earned by this employee, and the Clear button will clear only the name, hours-worked, and bonus amount fields. A Print button allows the user to print the form. Do not allow missing or bad input data to cancel the program; instead display a message to the user.
