Delete The Whole String Whose Starting And Ending Text?
Jun 6, 2011
it was regarding in vb.net text operations, i want to replace the text by finding some particular text.but the problem arises when the starting and the at the end delimiter of the string is something same every-time but middle thing keeps on changing so how can i work out with that?? str = Replace(str, "abcdparameter = xyz123;", "abcdarameter = my defined parameter;")
i tried to learn some regular expressions but i am not able to get that.the xyz 123 is same every-time....and also there is one delimiter at the end of the parameter string so anyhow you can select the whole line and replace it.

I'm trying to extract a piece of text from within the string, defining both a starting point and an ending point. For instance, say I want to search for the text found between "That is a " and " car" in the string "That is a red car", so it would return "red".I know you can use .SelectionStart and SelectionLength, but the length of the word can change, so the selection length can vary. What I want is to establish a specific starting point and a specific ending point from which to extract the text from the string.

I want to make a very small program where the user inputs a starting time and an ending time that is in "clock time (?)" and the program converts it to total minutes in one box and a decimal total in a second box. I have 4 textboxes, 2 are masked text boxes (military time) for input and two are not, for output and the math is coming out weird.
If I put a start time of 0925 and an end time of 1015, the results I'm expecting would be 50 total minutes and .83333 total as a decimal. I don't think I'm converting the textbox input correctly as I'm not getting anything near that. I am using a button to calculate and another to clear the boxes, just FYI. Also, I'm not sure what to do about any times that span the noon hour except to use an absolute value.
Public Function Time()
Dim StartTime As Double
Dim Endtime As Double
StartTime = txtStart.Text
Endtime = txtEnd.Text
txtDecimal.Text = (Endtime - StartTime) / 60
txtMinutes.Text = Endtime - StartTime
End Function

I'm using VB.Net in an ASP.Net 2.0 app to run some regular expressions that remove some unnecessary markup. One of the things that I'd like to do is remove span elements that don't have any attributes in them:[code]I'd like to remove the outer span elements. Unfortunately, my regex above gives me this as a result, since the closing span matches the first one it comes across:[code]

I am trying to delete the last line of a text file, then append new text to the end - The problem I have is that the code I have is set up to search for an Index, not a String, or the EOF line - I tried to modify it to search for the end string in the file, but that didn't work, either - Here's what I have:
'Delete last line
Dim lines As New List(Of String)(IO.File.ReadAllLines(LocalAppData & "settings.txt"))
'Remove the line to delete, e.g.

I have a completely basic program here that I want to simply take text from a textbox and the selection from a combobox, and then run the following:
CODE:
Obviously WKID and PROCESS are the variables it will be pulling from the data that was put in by the user. That code was just in a simple batch file that I made with 2 variables. I am wanting to pull those 2 variables in when clicking the "kill process" button, it will run a command simliar to the above and end a process on a remote networked computer.

I have a simple text file containing a list of names that I wish to sort. I was hoping for something simple like:
System.IO.File.ReadAllText("MyFile.txt")
System.IO.File.Sort("MyFile.txt")
System.IO.File.WriteAllText("MyFile.txt")
or something like that. Didn't want to actually write a bubblesort/quicksort routine myself.
I would imagine the routine would just rewrite the final file or would I have to make a new file and copy the contents back to the original?

How do I start writing a program that has 6 text boxes. A person would enter a member number if they have one, number of movies rented at $1.80 a piece. A Text box should then display Total Rental Price, and if a member number was entered, a 10% discount is given (the total of the discount shows up in another text box) and after there discount is applied the Amount Due is displayed in yet another Text Box.
My boxes are named:
memberNumberBox
moviesRentedBox
rentalPriceBox = $1.80
totalPriceBox
discountBox
amountDueBox
This is all supposed to happed when the customer clicks on a calculation button named: Button1
This is what I have so far, but I don't even know if this is correct, as I am getting 1 error relating to a name not being declared. Please help and clue me in to where to start!

I have a small service which right now I just want to test by printing some string that is passed in and stored in a class.
Problem is everything works fine, service even starts fine as long as I don't call PrintDocument's Print function.
The moment I do that, the service never starts and I get Error 1053:Service didn't respond, etc error.

I converted this app from VB6. I have 2 forms. Form1 instantiates Form2 via a Menu Item.I am having trouble getting Form2 to end when clicking close (X). If Form2 is 'idle' it closes fine; but if I am in a loop processing anything all the events fire, but it continues processing in Form2. I've tried messing with Dispose, Close, Application.Exit, Application.ExitThread. My last attempt was creating my own event to fire back to Form1 and dispose Form2 -- and it hits it but Form2 is still running. What is the deal? BTW if I use just Show vs ShowDialog -- Form2 just blinks and disappears.[code]
