What is faster?

[Xcoder]

Hello all,

What Im trying to find out is if using SendMessage is faster than using this with a RichTextBox:

RichText1.SelStart = Len(RichText1.Text)
RichText1.SelText = mystring

If so, I will appreciate if you could point me to the right Consts and maybe an insight of what to do. Thanks a lot.

Use the GetTickCount and SendMessage API calls:

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" _
  (ByVal hWnd As Long, _
  ByVal wMsg As Long, _
  ByVal wParam As Long, _
  lParam As Any) As Long
  
Private Declare Function GetTickCount Lib "kernel32" () As Long
 
Private Const WM_SETTEXT = &HC

Populate a long variable with the result of GetTickCount, then subtract this from another result of GetTickCount after you have done your comparison code.

I've put together this myself out of curiosity, was suprised at the results to be honest..

Have you figured it out yet or still trying? B/C now im kinda courious myself, so I may give it a try. From jstu looking at it, I think that send message would give the command slower, since all the messages are handled, compared to using a function directly.
