'''Does Tcl Support "SendKey" And "SendMessage" (For Controlling Other Windows Applications)?'''

22/09/2003

Does Tcl includes the ability to control other applications, e.g. notepad?
Other programming languages provide commands like Sendkey (VB) or Sendmessage (VC). 
So I can executing notepad, putting text into textbox and saving that in a file. 
That's all possible because of controlling menuoptions by sending Windows-Messages ...
It is possible in Tcl too? - [RS]: See [tcom] for COM support, but not sure whether Notepad understands that..  - JPT: You could also try [cwind] (http://mini.net/tcl/5019). I've used it once and it did the (simple) job I had to do.

'''Using Exec To Capture A Child Processes Stdout And Stderr'''

Sep 26 - 2003
I want to make a frontend to gcc in tcl.

    if {[catch {exec gcc -c $Compiler_Flags $Filename } Result]} {
      puts $Result
      exit 1
    }

I want to map gcc's output messages to stdout and stderr, while the command runs.
I could direct it to a file, but we'll proberbly be running this frontend,
several persons at the same time. - [RS]: Experiment with
 eval exec [list gcc ... > @stdout 2> @ stderr $Compiler_Flags [list $Filename]
