Detect For A Specific Character In A String?

Jul 11, 2011

so in a program I'm working on in VB.NET I'm trying to make it so I can take in a list of strings (each on a different line). For each line I want to take in the line, and break it up into three parts. The first part goes from the beginning of the string to the first colon in the string, the second part goes from the first colon to the at symbol, and the last part goes from the at symbol to the end of the string.

For example, I'd take in a line of the series of lines: hello:world@yay

I'd want to break it into three separate strings of "hello", "world", and "yay".

How would I do such a thing in VB.NET?

VS 2008 Random - New Character Out Of The String And Then Remove The Character From The List Of Characters

Dec 12, 2010


For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.

Filling Out Web Form With Character Count?

Jun 22, 2010

I am new to programming with vb2008 and I am trying to fill out a form on line. The form looks for keystrokes and keeps track of the number of characters typed. There are two elements on the form that use this method. The first area will allow me to fill in the data using the usual method of setting the attribute "value" of the field as the data I wish to insert. But the characters are not counted. The second area does not fill at all.The code for the fields are as follows.

<div id="fck_editor">
<input type="hidden" id="body" name="body" value="" style="display:none" /><input type="hidden" id="body___Config" value="" style="display:none" /><iframe id="body___Frame" src="/includes/js/fckeditor2.6.4/editor/fckeditor.html?InstanceName=body&Toolbar=Default" width="649" height="410" frameborder="0" scrolling="no"></iframe>
