I use Fileystemwatcher to watch a certain folder on our network share and wan't to count the lines in a textbox. I have 2 richtextboxes, the first one will display the line number and the second one displays the change/deleted/renamed file. I am able to display the total of lines in a label, but also want to show the line numbers in a richtextbox, but the problem is that it adds the number to the current, it needs to add the number on a new line.
Private Sub textFolderActiviteit_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles textFolderActiviteit.TextChanged
textFolderActiviteit.SelectionStart = textFolderActiviteit.Text.Length
textFolderActiviteit.SelectionLength = 0
textFolderActiviteit.ScrollToCaret()

I have a RTB which I import with a set of 7 or 9 didit numbers, 7 for Staff and 9 for Students. e.g. Staff numbers [code]and depending on what is selected in a list box ('Student' or 'Staff') will generate a string to create user accounts. To further error check I would like to check if a line in the RTB = 7 And Listbox = "Student" Then msgbox("Data mismatch between User ID and Account type")
View 4 RepliesI'm back again as I'm waiting for the coffee to kick in and have another question that seems to be not causing my brain cells to fire correctly.
I've set the following code to determine the line numbers of all rows returned from the procedure loop.
linenum = 0
Do While (rsData.Read())
linenum = linenum + 1
loop
Now I'm trying to code a button that will move users to different sections depending on the linenumber returned.
So if there's only one linenum with a value of 1, they get a button to 'Apply'.
If the total linenum values are greater than 1, they get a button to 'select apply date'.
Now again I'm having a brain fart and can't think of the logic if theres a linenum of 1+ how to determine the button should be displayed. It needs to include the value of 1 as well as there are more than one linenums so the button should display the 'select apply button'.
I need a TextBox to resize depending on the number of lines entered by the user, I note that TextBoxes has no AutoSize Property.
Is there a way to Count the number of Lines in a Text?
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.

View 3 Repliesdesigning a Windows based computer program that will allow a user to enter some number (n) and a choice of a count up or count down for that many numbers. So for example, the user enters 5 as their number and selects the count down option, the message box displayed would contain the message: "Here are your numbers: 5,4,3,2,1,0"

View 6 RepliesI'm new here, but have been in and out for a while. Past threads have been helping me along thus far.
I'm currently developing an app which essentially needs a way for me to search in a text box or file for a specific string, and extract the line on which that string appears on. It will be unique, and the syntax is the same on each line. It has basically 2 ID numbers, and is laid out like this:
123456|123456
So, I'd need to search for the first part before the |, and then get the line so I can get the bit after the |, which is the important bit for me.

View 5 RepliesI've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?
In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:
Dim user_data_file As String = "user_data.txt"
edit_input = New StreamReader(user_data_file)
Dim edit_line As String = edit_input.ReadLine
[CODE]...
However, I can't find any methods that will allow me to do this.
