What is the simplest way to count the number of occurances of a specific character in a string.[code]
This is what I have, but It doesn't work with strings for some reason (only text files):
How would you select the last part of a string starting at a specific character count. For example I would like to get all text after the 3rd comma. but I get an error saying "StartIndex cannot be less than zero."
Dim testString As String = "part, description, order, get this text, and this text"
Dim result As String = ""
result = testString.Substring(testString.IndexOf(",", 0, 3))
I am writing a hangman type game and I am displaying the word to the user in a label as all *'s, but I cannot figure out how to have just one of the *'s changed in the label to the correct letter when the user inputs the correct letter into the text box and clicks the check letter button.Everything else in the program works perfectly, except for this part.[code]When I use the .Replace it changes all of the *'s to the correct selected letter.View 2 Replies View Related

I'm scanning through all characters in a textbox. Then the program counts how many of each character is in the textbox. Here's the code which adds all characters to a list:
For each c as char in TxtBox
Everything's working fine, except this will also add returns to the list, which I don't want. I thought I could write like this:
If c <> chr(10) Then

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?

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.

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.
<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>

Know The Coding To Count How Many Character Are In A TextBox Labeled

I have an array of items where i have separated the first two characters, which in my case are ID tags. I have populated my CLBox and the output is like this

I've been working with the substring command and after coding up all the things I needed it to do, I saw a post on here where the "For Each" statement was used basically to do the same thing.Lets say we just want to take a string apart one character at a time and add each character to a label. Which would be more efficient?I made a cheap example to show ...
ABinary = "0110 1100 0001 1011"
For x = 0 To Len(ABinary) - 1
