look at it with olly and see what the "sizeof" operator is yielding

   mov commun.defautcharformat.cbSize,sizeof CHARFORMAT2
   mov commun.charformat.cbSize,sizeof CHARFORMAT2

the more simple case to solve is the text selection.

   mov commun.charrange.cpMin,0
   mov commun.charrange.cpMax,-1
   invoke SendMessage,Hredit,EM_SETSEL,0,-1
   ;invoke SendMessage,Hredit,EM_EXSETSEL,NULL,addr commun.charrange

As a alternate soluce,i used the EM_SETSEL message (Edit message) that work.
The EM_EXSETSEL failed with no visible reason and there isn't problem with unicode and the size of the structure.
Size of  charformat2 is 9C

glad you got it running  :U
i mentioned the sizeof operator because i had seen a number of other posts regarding sizeof problems
