How do I add a space between every character in a string of text?For example:Change abcdefg"
To "a b c d e f g"I have two text boxes on my form, one for input, the other for output of the re-formatted string.
I've always use String.IsNullOrEmpty to check for a empty string. It recently come to my attention that a " " count as not a empty string. For example,
Dim test As String = " "
If String.IsNullOrEmpty(test) Then
MessageBox.Show("Empty String")
[Code]....
It will show "Not Empty String". So how do we check for " " or " " in a string?
edit: I wasn't aware that " " count as character.
I'm trying to build a list that will be used as the in clause of a select statement. The requirement is to have the user enter a comma separated list of descriptions. Each description can contain spaces so I can't remove the spaces before splitting by comma to add the single quotes around each description. I want to remove all white space after a single quote since no description will start with a space. What's the best way to do this in VB.NET? Regular expression or a string function? Here's what I have so far.

I'm trying to split a Yahoo historical stock price csv file, downloaded into a string, by what looks like a space character. I want a new row for each split.

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 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.

I have a string that has three spaces in it.
In the following examples, underscores represent the spaces:

I need to remove just the first space. Now, i tried just replacing the space with nothing, like so:
VB.NET
If s.Contains(" ") Thens = s.Replace(" ", "")End If
But, that removes every space. I also tried .StartsWith, but it still removed every space. I didn't actually expect that to work, but if I hadn't tried it, I wouldn't have actually know.

So I basically want to make sure that a string entered by the user is valid. Valid being over 10 characters, containing only upper case characters, and only characters A - Z and spaces. The first two were easy, but I'm having trouble with the third, though.What I originally attempted to do was create a loop which checks if the first invalid character is present with the InStr function, by using the characters ASCII value. The next ASCII value is then checked, and so on until it has checked the string for every single invalid character. If an invalid character gets picked up, 1 is added to a variable, and after the loop is finished executing, if the variable is no longer 0, invalid characters have been detected.

View 9 RepliesI have an string that is returned from an xml file and looks similar to this name1="test 1" name2="test2" name3="test 3".I want to split this into 3 elements of key=value. I can't just split using a space because some of my values may contain spaces, e.g., test 1.So, I'd like to split the string using the " before the space. I've tried many variations but can't figure out the correct syntax to specify that my split characters are a " followed by a space. For instance, I've tried text.split({""" "}) but that returns elements split by " and ignores the space after the ".It shouldn't be this difficult. Can someone please help me with the correct syntax?
View 2 RepliesI try to remove empty space from a large string, using replace(), and using regex.
the replace method:
replace
Do While (stripped.IndexOf(Space(2)) >= 0)
stripped = stripped.Replace(Space(2), " ")
Loop
and with regex using its replace with : "/ss+/" - regular expression.
but I am still stuck with empty strings such as :
temp ""String
these string have lengths ranging between 3 and 8, so I have tried to adapt the replace function with something like this:
replace 2
Do While (stripped.IndexOf(Space(4)) >= 0)
stripped = stripped.Replace(Space(4), Space(1))
Loop
