.net - Remove Any HTML Within THE <TABLE> And </TABLE> Tags?
Dec 22, 2010I have a html text file and I am trying to remove any HTML tags in tables, i.e. remove any HTML within THE <TABLE> and </TABLE> tags.
However, what's really weird is that the regex that I use, (?<=<table((?!</table).)*)<(?!/table)[^>]+>, works perfectly in PowerGREP or EditPad Pro, however, when applied in vb.NET (or Expresso) to the VERY SAME text, it does NOT work! I just use a simple replace method: newString = Regex.Replace(oldString, "(?<=<table((?!</table).)*)<(?!/table)[^>]+>", string.Empty, RegexOptions.IgnoreCase)?
Below is the example text:

Windows - Remove File If Application Is Not Running?
Apr 6, 2011Not sure whether this is possible, but I'm creating a file encoding applcation. When a file is decoded, it is saved temporarily in a temp directory, after which it can be opened regularly. However, I actually need to be certain the file is removed as soon as the application that has opened it, has closed it (e.g. has shut down). Otherwise, the decoded (secret) file is just hanging in the temp directory without supervision.

Loop While Application Is Running?
Nov 19, 2009I am writing a program that is connected to an rs232 port and I need it to constantly be monitoring the incoming data. I think there are a few ways of doing this like checking the buffer but I need this to be running while I am connected to the port. I have a play button and a pause button for the port. When the play button is pressed, the port is open and the button is no longer enabled until the pause button is pressed. I need to have a while loop running the entire time the play button is no enabled, or pressed. I am having a hard time knowing where to implement it in the code.

View 10 RepliesRunning A Loop When A Button Is Pressed?
Sep 30, 2011I'm developing a interface in VB.net which will control two stepper motors. Counting on your tips I managed to control them manually I mean, there're 4 buttons used to move the motors clockwise and anti-clockwise. The point is, the main part of our project is control the motors automatically. Our idea is based on two editable fields, X and Y, where the user would insert the displacement value he'd like the motor to move. After filling up both fields, the "GO" buttons would be pressed. So the loop would run depending on the displacement values in X and Y.
Attached you can find the main screen:
Below you can find the main code.

VS 2010 : Use Controls While A Loop Is Running?
Oct 4, 2011Basically what I have are two loops, one inside the other, that will run until the given condition is met. Exactly what I want. My problem is that I want to be able to use the controls, like buttons, while a loop is going on.
I originally did not think of this until I had built this part of my program, what I want to know is if there is a way to use controls while a loop is going on or if their is an alternative.
1)I know timers can be used to meet these goals, but they did not work out as I had hoped and using two timers (1 to represent each loop) I do not believe is efficient.
2)I have considered using recursion, but have found this may not be very efficient either and am not quite sure if this will do what I want.
These loops run as long as the number the user inputted. So it could theoretically run for 100,000+ times. I am not looking for speed, but it would be good if there were a faster method that allowed me to use controls while it loops.

View 5 RepliesTextbox Text Not Updating While For Each Loop Running?
Mar 8, 2012Windows Forms, VB application... Forgive me in advance for this very elementary question but I am overlooking something really simple here. I would like to have a label show the current value of a variable as the for each loop runs.. I created a very simple Button Click event to figure out where its failing. As it is right now the value does not display until after the for each loop finishes running, which it should actually display the counter value each time it runs through... I know this is possible and really simple because I did it years back but for the life of me cant figure out why I am missing the bar as it should constantly update the label to reflect that?Test Sub is as follows:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim counter As Integer = 0
For x As Integer = 1 To 200000

While Loop - When Running The Debug The Program Crashes
Mar 15, 2012I've been having a bit of a problem using the while function.
Here is my code (Simplified):
Dim RandomNumber3 As Random
Dim RandomOutput3 As Integer
[CODE]..............
When running the debug, the program crashes, and when I step into the program, I find that this While statement becomes an infinite loop. This is a program that uses random number generators to assign a value to something, and this while statement is necessary so that there is never two of the same values showing (RandomOutput, RandomOutput2 & RandomOutput) Have to be different to one another.

View 2 RepliesVS 2010 - DataTable - Change / Remove Some Data Using Loop Does Not Work
Jan 24, 2012I'm pulling data from my DB, adding it to a DataTable and binding that DataTable to my DataGridView. Before I bind the data, I need to change/remove some data. When I loop through the rows and use a Select Case, just for this column, it doesn't work. But if I use an If, it works fine. [Code] In the example above, the "Pass_Flag" row works just fine, but the "FailureCD" does not. But after the Select, with the If statement, it works. In the example, I'm casting the row as a string first and then an integer. I tried casting to an integer in the select case and it doesn't work either.
View 4 RepliesVS 2008 UI Threading - Move/interact With Both Forms While The Loop Is Running ?
Oct 17, 2009When it comes to threading. I've managed to adapt one of JMcIllhinney's backgroundworker codebank examples to somewhat suit my needs, but not completely. I have a main form, and a second form that appears while I'm running through a for loop. It informs the user what is currently happening. I set up a backgroundworker that allowed me to continue to use the main form during the for loop, but the other "status" form was completely frozen, and any labels or graphics were shown as white boxes. I am struggling to figure out how to be able to move/interact with both forms while the loop is running.

Remove Row From DataSet If Bound Table Is Sorted?
Aug 31, 2010I have a DataGridView that is bound to a DataSet and I allow someone to remove a row from the table and I remove the row from the set. My code looks like this:
ds.Tables(0).Rows(dgCourseList.SelectedRows(0).Index).Delete()
My problem I found is if the grid gets sorted the index of the rows no longer corresponds to the indexes in the DataSet. As a result the wrong rows get removed from the set.
Can I solve this problem with maybe having to sort the DataSet on some sort event of the DataGridView?
VS 2005 - Remove Empty Column From Table
Oct 3, 2011I am using TextFieldParser to Read a Tab Delimited Text DataFile. The problem I have is that some times the data file (3rd party provided) contains an extra Tab which therefore creates an extra column. I need to remove this unnecessary column. Some columns will have rows that are empty so I cant just delete the column if it has a blank row, So I think I need to loop through each column and if if every row is blacnk then delete that column.
Here is the code that reads the file, I was going to remove the column from the table called table before I populate the table called dtAll , which is what my program uses
Dim safeFileName As String = IO.Path.GetFileName(Me.OpenFileDialog1.FileName)
