I am kind of new to Visual Basic and I got stuck doing a sample Windows Form program. I was trying to write a String into a text file. But I just couldnt get the command for the new line character whereby each time, the new String is concatenated to the next line instead of the same line. I know that in C the new line character is used. But what about in Visual Basic?

Why must the line continuation character be the last one on the line? Is there a technical reason for this or is this a usual Microsoft "feature"?
In other basic dialects you can add a comment after it, but not in VB.net, so I'm curious as to why Microsoft decided to not allow comments on these lines.

View 1 RepliesRetrieving strings from a serial port with ReadLine works fine as long as the line ends with a linefeed chr$(10).However if no more strings are available to be read, Do Loop or For Next hang up waiting for the linefeed which never occurs.I believe using chr$(0) in place of linefeed would still work with strings ending with a linefeed..Just that the linefeed would be output.I have the complete MSDN Library.
View 2 RepliesI'm trying to find a character in a specific character space, on a particular line, for instance:

I am creating an interface to control my av receiver, so far I can control it but now I want to receive the feedback from it and process it. The feed back I get is in the form of "!1PWR00"[End of line]. I am having a problem with the end of line part, what is end of line in VB? If I display the feed back in a message box it shows the end of line as a little arrow pointing to the right, how can I look for this end of line character in the datareceived in my code? CR is easy as it is simply vbCR. So what do I use for end of line?

but yet this fails.. (the output isn't itself in a new line) what's the explanation for that?From what I know, doesn't System.Diagnostics.Debug.Writeline does something which looks like this:
System.Diagnostics.Debug.Write(input)
System.Diagnostics.Debug.Write("

so regardless of my input it should always have a newline char even if there is a terminating 00 char in my input?

View 3 RepliesI am working on a sub that essentially needs to open a text file, and replace all instances of a certain character with a unicode character. 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.

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.

View 7 RepliesIn my VB.NET application I compare words that are recorded using IPA, many of which have many diacritic marks. In one of the comparisons, I compare the words character by character.
