Here is my

OK, SO i have this program that outputs all the servers on a specific game. It outputs it to a text file. HOWEVER, There is a lot of annoying spaces. This is kind of hard to explain, so ill try to explain it. This is what The text file looks like. [Code]
As you can see, they have these annoying spaces. What I want to do: 1. Get rid of the spaces, BUT KEEP A SPACE BETWEEN THE IP AND THE PORT. 2. After the spaces that are bad are gone, I want the program to output each single IP AND port To its own text Box. It doesn't matter is the textbox of the IP and Port are separated, It can just be one textbox with the IP and port, with a space between them. Thats about it. I have the GUI done, and the rest of the programming, all I need now is this. Reformat without spaces > output each separate line of text to a separate textbox > TYTYTYTY
PS, is there a way for VB to send a command to the command prompt? Say, I wanted it to open a CMD box and send ipconfig into that box, what would that be?

I have 2 questions:
1) Whenever i change the text in my richtextbox it flickers, as part of my program a richtextbox is changed every 1-2seconds and the flickering can get extreemly annoying, anyone know a way to stop this?
2) Im looking for a function that when passed a line will run through a textfile and remove said name for example in a textfile that contains
One

Three
Four
you could pass removeline("Two")
and it would resave the textfile as

View 4 RepliesI'm trying to search for text that is known to be in a TextBox.
Once it is found, I want to return the line number it was found on.
Also, I would like to know how to delete all blank lines from a TextBox.
These two problems have been plaguing me for the last 2 days.
a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.
