View 3 RepliesRegex - .NET: Manipulating TextBox Input: Dash Every 5 Characters And Removing Special Characters?
Dec 21, 2011Essentially I am trying to replicate the Windows 7 (In-Windows) activation key TextBox form. The Form where it will auto capitalize letters, remove or deny all non alphanumeric characters except dashes every 5 characters that will be auto-input.I assume this can be done with a fairly complicated replacement Regular Expression but I cannot seem to create one to fit the needs.
This is an Example of what I have right now, but it creates an infinite loop as it removes all characters including dashes, than adds a dash, which changes the text and removes the dash again.

Jul 22, 2011I can't get a zero into a text-box, what I'd like to achieve is this: if the textbox is zero, then I want it to remain as a blank, until I enter value to that field.Actually When I activate the field via some other control, then I Never wants to display "0" zero in Textbox Fields, before operation done.

Scan A Text File To Determine If It Is A Text File And If It Contains Any Non-ASCII Characters?
Jan 27, 2012what would be the optimum code in VB2010 that check a file to determine:
1) is it a text file, and
2) if it is a text file, does it contain any non-ASCII characters
Note that LF, CR, and EOF would be expected, and should not be flagged. I can think of 3 - 4 ways to do it, but there may be a 'best' way in terms of simplicity and speed.

So if my variable is called "removeThis" then I need to be able to Read through the textfile, find the line that is equal to the removeThis string variable, and then rewrite the whole textfile.

View 2 RepliesRemoving Textline From Text File?
May 5, 2009I know this has been asked like a million times, but I cannot seem to find a solution that works for me. I have a text file..and lets say its named Test.txt.I have like a list of stuff in the file and I have a Remove button. I also have a listbox that has the contents in the Test.txt file listed on the form_load. So basically to try to explain this better..what I want is to delete the line that is selected in the listbox when I click the remove button. Let me explain in an example.The Test.txt has the same contents as the Listbox..so say my list is like this:
Hi
How
Are
You
If I have Hi as my Listbox.SelectedItem then I would like to remove that line from the Test.txt. I tried to load the contents of the file in a TextBox too and I can search and find the text in the textbox and focus on it and highlight it but I cannot delete it from there too.
Removing URL From List In Text File
Nov 12, 2009I am attempting to get my program to store its, in this case, a Url list in a text file. This should be relatively simple and so far it has been, writing to the document has been easy and it has all worked well, however, I have been trying to get my program to remove a url from this list too. To achieve this I have created a temporary text file, named 'FavouritesTemp.txt' and write the content of a listbox (with the target of the delete command removed from it) and then replace the old text document with the new one. But I keep getting an error from this - saying that a process is already accessing this file, even though I have just created it! I have attached a picture of my error and the code I am using underneath.
Code:
System.IO.File.Create(My.Settings.ProgramInfoStorePath & "FavouritesTemp.txt")
MsgBox("Created FavouritesTemp.txt")
Dim FavouritesWriter As New System.IO.StreamWriter(My.Settings.ProgramInfoStorePath & "FavouritesTemp.txt", True)
