Here is an alternate version of the code. I extracted the core functionality into a separate .inc so that the main program only needs to call a single function. This version is not a commandline utility. It automatically outpulses the key sequence into the active window. The expectation is that the user would press a key combination that is recognized as a hotkey (by a utility like Auto Hotkey or Macro Express), which would trigger an auto hotkey macro which would run this PowerBASIC exe. (If you try to run the program by just launching the exe in windows explorer, you will get undesirable results because the program will outpulse its key sequence to the active window (which would be windows explorer.)

I also added the ability to include a pause within the text sequence with the string {DELAYxxxx} where xxxx is the number of milliseconds.

Note that you still may wish to refer to the code in the previous posting to see how to manage activating specified window names before outpulsing the keystrokes.

Comunicating with Calculator Plus using AutoHotKey

Not quite on topic but close. I was running a PB program that required numerous repetitions of Ctrl+V to send a string from the Clipboard to Microsoft's CalcPlus and then retrieve the result back into PB via the Clipboard with Ctrl+C. Lacking working knowledge of API and very new to AutoHotKey, I wrote this script for the latter named CalcPlus.ahk

Code:

#ErrorStdOut          ; Send error reports to StdOut
ClipWait              ; Wait for clipboard to contain text
SendInput %clipboard% ; Send clipboard contents to CalcPlus
Clipboard =           ; Clear clipboard
Send ^c               ; Send CalcPlus contents to clipboard
ClipWait              ; Wait for clipboard to contain text
Exit                  ; Terminate script

and this little PBCC 6.02 code (here trimmed down to the basics)

Code:

Function CalcPlus( _
    ByVal s As String _         ' String to pass to CalcPlus
    ) As String                 ' Output will be the CalcPlus result
    ' For coding s, see CalcPlus help file topics:
    '     "Using keyboard equivalents of Calculator Plus buttons"
    '     "Using key sequences as functions"
    ' and experiment. Also see the AutoHotKey help file topic:
    '     "Send / SendRaw / SendInput / SendPlay / SendEvent: Send Keys & Clicks".
    Static ProcessId As Dword   ' Nonzero after first pass
    Local ClipResult As Long    ' Clipboard error if zero
    Local t As String           ' CalcPlust result string
    If ProcessId=0 Then         ' Do first time only
        ProcessId=Shell("C:\Program Files\Microsoft Calculator Plus\CalcPlus.exe")
        Sleep 50                ' Must wait at least ~30 msec (on my computer)
        ' Insert code below.
        If ProcessId<=32 Then ? "Shell function failed. Cause: "; Cause: GoTo ErrorHandler
    End If
    Clipboard Reset, ClipResult: If ClipResult=0 Then GoTo ErrorHandler
    Clipboard Set Text s, ClipResult: If ClipResult=0 Then GoTo ErrorHandler
    Shell "C:\Program Files\AutoHotKey\AutoHotKey.exe "+ _
        """C:\Program Files\AutoHotKey\CalcPlus.ahk"""
    Clipboard Get Text t, ClipResult: If ClipResult=0 Then GoTo ErrorHandler
    Function=UCase$(t) ' Change "e" to "E"
    Exit Function
    ErrorHandler:
        ? "Clipboard error": Close: WaitKey$: End ' Terminate
End Function

and it worked nicely. The program must run by itself which was just fine for my purposes.

Edit: ProcessId contains the following documented codes if Shell failed, thanks to an MCM post that lead to:
http://www.oehive.org/node/528.
The following could be put after the Shell function:

Code:

Local Cause As String
Select Case ProcessId 
Case  0: Cause="The operating system is out of memory or resources."
Case  2: Cause="The specified file was not found."
Case  3: Cause="The specified path was not found."
Case  5: Cause="Windows 95 only: The operating system denied access to the specified file."
Case  8: Cause="Windows 95 only: There was not enough memory to complete the operation."
Case 10: Cause="Wrong Windows version."
Case 11: Cause="The .EXE file is invalid (non-Win32 .EXE or error in .EXE image)."
Case 12: Cause="Application was designed for a different operating system."
Case 13: Cause="Application was designed for MS-DOS 4.0."
Case 15: Cause="Attempt to load a real-mode program."
Case 16: Cause="Attempt to load a second instance of an application with non-readonly data segments."
Case 19: Cause="Attempt to load a compressed application file."
Case 20: Cause="Dynamic-link library (DLL) file failure."
Case 26: Cause="A sharing violation occurred."
Case 27: Cause="The filename association is incomplete or invalid."
Case 28: Cause="The DDE transaction could not be completed because the request timed out."
Case 29: Cause="The DDE transaction failed."
Case 30: Cause="The DDE transaction could not be completed because other DDE transactions were being processed."
Case 31: Cause="There is no application associated with the given filename extension."
Case 32: Cause="Windows 95 only: The specified dynamic-link library was not found."
Case <=32: Cause="Undocumented."
End Select
