Hello Mike,

OK, I give up what's STDIN?

Hello Mike,

Open a window.

sequence line
fn=open{"yourfile.txt","r")
Open your file and read it, line=gets(fn).

Put the text in your window with, wPuts(yourWindow,line)

Also see get() it may be easier to get it all at once.

Hope this helps.

By default all windows programs will receive standard input from the console. If
the program does not have a console then the exw interpreter will open one for
you. The exw interpreter will not use a previously opened console. If you are
writing a console application then using exwc.exe would be the way to go. This
interpreter will use an existing console.

You can prevent a console from being opened by first redirecting standard input
to a file. Euphoria does not have a native function to do this but it may be done
with the API function SetStdHandle(), which expects as input a handle to the
desired file. Unfortunately, Euphoria's open() function can not be used to obtain
this handle. open() obtains a private handle that can only be used by the native
Euphoria file functions.

A suitable file handle can be obtained by using the API function CreateFile().
The function is badly named but performs the same function as Euphoria's open().
CreateFile() has many options and can be quite confusing. I haven't used Win32Lib
in some time but I do not believe it has this function.

It seems to me that there must be an alternative to using standard input in this
case. I haven't actually done this but I believe the process outlined is
accurate. If I had a better idea of what you were trying to accomplish I could be
of more help.

Hello Mike,

If that's the case try:

procedure onKeyPress(integer self ,integer evebt, sequence parms)
--you can put position here
  wPuts(Window1,sprintf("%s",parms[1]))
end procedure
setHandler(Window,w32HKeyPress,routine_id("onKeyPress"))

In my way of thinking there are only two ways to get input, from a file or from
the keyboard. If ther's a third way called Standard input them I'm lost here.

Another thought you might also try w32HKeyDown.
