Sort A Simple Text File Starting With The First Character And So On
Sep 21, 2009I 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?

One Set A Maximum On Number Of Character A Textbox Can Use?
May 14, 2011My issue is that some websites only allow say 15 characters maximum to be used to create a user name where other sites do not. Currently I have one text box on the screen and a button, and a web browser that navigates to two sites.Site #1 has a cap of 15 characters max to create a user nameSite #2 doesn't have any maximum amount of characters to use.I am wanting to know how I can enter lets say a 20 character username into the text box and have the code set a max of 15 characters for site one and nothing for site 2. I was thinking that this could be done when passing the information from the text box to the text box on the screen with something like
Textbox1.Text.value.length= maximum 15
Site #2:
Textbox1.Text

View 3 RepliesIDE :: Send A Character To TextBox Inside A While Loop?
Feb 11, 2010I would like to show that the computer is busy and not frozen during a long file transmitted over Serial Port.I have the following loop.The intention was to show one "*" for every line sent.
While (fs.EndOfStream = False)
lineRead = (fs.ReadLine)
TextBox1.Text = "* "
SerialPort1.Write(lineRead)
End While
I can see the data sent on the Scope but the chain of "******...." show up after the transmission ends.The WHILE LOOP is actually working but the TextBox1.Text = "*" is not writing to screen.I would like to see the train of ******** same time as the transmission is active.The * is to show that the computer is busy and not frozen.Writing a copy of the actual serial data transmitted to screen is also another option that I can use.
Masked TextBox Adding Extra Character
Oct 31, 2010I'm working on a project that employs a masked text box with a mask ####. When I run the code it pulls the value from the textbox then clears it. When I try to type in it again the first character is added before the mask. (ex. 1#### instead of ####) I've figured out that pressing backspace before trying to enter numbers again resolves this issue. Is there a way to send the backspace function rather than the chrs(8) like SendKeys.Send(Keys.Back) does?
