How To Calculate Number Of Lines In A Text Box
Feb 27, 2009
I am hoping that someone can help me with a problem I've got at the moment using Compact Framework.Net 2 SP 2.At the moment I have a UI with a series of text boxes and each textbox displays the contents of a database field. These are shown one beneath another with a scroll bar on the right hand side of the form. Each textbox has a set width which might.I would like to adjust the height each text box based on the number of lines it is holding, the font size and the font in order to avoid using scroll bars on each textbox.[code]

Is there a way to see how many lines are in a text file? This also includes blank lines. I have seen a lot of code in this forum before related to my question, but they stop if there is a blank line. I want it to be so that if there are like 10 blank lines

Basically, every time an entry is made - all of the proper data gets put out to a central Listings.txt file and then a specific .txt file for that area. When the user enters the recall form, they can view the listings for all or whichever area they've selected. That works quite fine. However! We also need to include a summary of how many are in each section. Not thinking properly, I started to do this with a counter - until I realized that a counter will lose its value once the program shuts down. My current idea is to count the number of lines in the text file (it outputs 8 lines per listing, so everything would be in values of 8) and then divide that by 8 - but after some searching I haven't been able to find a piece of code that will allow me to get an integer that relates to the amount of individual lines in the file.

As you will see from the code below I need to be able to tell before the array runs how many members of the array there are or else the program will crash. How can I redim the array depending on how many lines are in the text file (RECORDS.txt)

I have written a simple script to get a bunch of lines from a text file (they will be filenames eventually) which are split by new lines and puts each one into an array..
Dim ary() As String
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If My.Computer.FileSystem.FileExists("C:MenuFiles.txt") Then
[code]....
The only thing I can do for now is either use the substring function to remove the first character from all array values after 0 but I don't like that because it's messy and what if the split "works" as I want it to one one of the lines and knocks of the first character when I don't want it to.

I have a text file containing lines of data (File 1). I need to delete all the lines in another text file (File 2), which are found in file 1.So I could read file 2 line by line. And then once the line has been read, read file 1 line by line to search for a match. But that's going to be painfully slow.Or I could read file 2 into memory. And then read file 1 line by line and REPLACE the lines in file 2 with nothing, therefore deleting them. File 2 could be 100 mb, so I'm not sure about reading it all into memory.

How do I calculate the difference between two dates to display as a number in days?I have 2 text boxes (txtHStart_Date & txtHEnd_Date) I have used an Ajax Calendar Extender to enter the dates in each of these text boxes.I would like to get the difference between these two dates to show in a seperate text box (txtNoOfDays)
I've seen the timespan function but can seem to get this to work. I'm not to sure how to declare the text boxes as the dates I would the calculation to be made from
Code:
Dim D1 As Date
Dim D2 As Date
Dim ts As New TimeSpan
D1 = txtHStart_Date.Text
D2 = txtHEnd_Date.Text
ts = D2 - D1
But I know this isn't right. I also don't know how to get it to display in the 3rd TextBox.

I am trying to learn how to use the modulus operator.this excersise is a change calculator and is supposed to calculate the number of dollars , qtrs, dimes, nickels and pennies from the change that is calculated.
in the form if i put a value in for owed = 30.00 and paid 34.25 my dollars returned = 4 and that is correct but the number of qtrs = 0 and should be 1. I am not sure how to correctly use this - any assistance you can provide is great - this is purely educational

So I need to get a button to take the number that a user enters into a textbox, calculate the factorial from that number, and display it in another textbox. I can't seem to get this to come out right.
Here's some of the code I've been playing with.
Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click
Function Factorial(ByVal txtFactorial As Decimal) As Decimal
If txtFactorial <= 1 Then
MessageBox.Show("Enter a number greater than 1")
Else
txtAnswer = Factorial(txtfactorial - 1)
End If
End Function
Now I have to just work out the code part. Can a function be under a button? I'm getting an error about that. I'm also getting an error about the txtAnswer=Factorial(txtfactorial-1) part of the code.
