I was wondering if anyone could help me with the following problem:
I am working with a csv file (it contains two columns of numbers), which as a last character has a comma and I would like to remove that comma from the file.
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'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 do this by reading the original text file byte by byte, converting it to a character, and then either adding that character to a memory stream or writing the unicode character to the memory stream. Then I'm saving the memory stream to the original file.
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.
