  Hi,
  
  I have a string say for eg:
  
  dim str as string="3-1/8"x13-1/2"x1'~ARCH~GLULAM~HEADER~DFIR~HEAD~SIMPLE~HEAD"
  
  I want to replace the word "HEAD" to "ABC"
  
  when i use the replace function of .net it correctly replaces HEAD to ABC which is correct and also it replaces HEADER AS ABCER..Which should not happen and is incorrect..How to replace only the word HEAD To ABC and Not HEADER
  
  Thanks in Advance.

  Hi,

   You can use regular expressions to match HEAD and NOT HEADER

  Or

   if HEAD always appears at the end og the string you can do a replace on the end of the string

  Faster way is byPassing: you replace HEADER with some temporary text, then HEAD with abc, and then replace temporary text back with header
