I'm receiving bytes over a socket and displaying in a text box. In the
responses I receive, some lines are delimited with x0A and others with
x0D0A. I'd like to search for x0A and replace with x0D0A, but only if x0A is
preceeded with x0D - so I don't end up with x0D0D0A.
Right now I'm searching for x0D0A, replacing with x0A, then searching for
x0A and replacing with x0D0A. Seems a little ugly.
Is there a better way to do this? I thought maybe regular expressions, but
don't know much about regex.
TIA,
Mike

Mike,
Perhaps you can do some bit fiddling here.
As you read your stream look for the bit pattern (token) x0Dx0A using the
XOR statement
If xor yields zero then the bit patterns are identical.
Make your replacement in the output stream
move forward in your input stream the lenght of the token
Else
move forward one bit in your input stream
End If

This sounds like a good use of a RegEx
The following site seems to be a good intro to Regular-Expressions:
http://www.regular-expressions.info/
I'm sure there are others.
Unfortunately I do not use RegEx enough to give you a good working sample.
I believe you will need to use RegexOptions.Si ngleline to allow treating \r
& \n as characters.
Note: in RegEx: \r = x0D while \n = x0A.
Hope this helps

Hello,
I've been just investigating IE conditional comments - hiding things from
non-IE/Win browsers is easy, but I wanted to know, if it's possible to hide
code from IE/Win browsers.
I found <!> in the original MSDN documentation, but this is (although
it is working) unfortunately non-validating gibberish.
So I fooled around trying to find a way to make it valid. And voila:

Hi all,
I need to write a function to search and replace part of a char*
passed in to the function. I came up with the following:
char* search_and_replace(char* source,char search,char* replace){
char* result;
size_t l = strlen(source), r = strlen(replace), i;
int number_of_replaces = 0;
for(i = 0; i < l; i++){
if(source == search)

Can you do a search for more that one string in another string?
Something like:
someString.IndexOf("something1","something2","something3",0)
or would you have to do something like:

((someString.IndexOf("something2",0) >= 0) ||

I was just thinking that I understood the conditional operator when I coded
the following expecting it to fail:
int a= 10, b= 20, c= 0;
((a < b) ? a : b) = c; // a=0
a=20; b= 10;
((a < b) ? a : b) = c; //b=0
Now since the expresion 5 = c is not valid I did not expect the above to
work. But it does work. Why? I thought that the ?: operator would evaluate
