sending alt/key messages

[Russ Srole]

Does anyone know how to send a message to windows to force a
menu pulldown? I have an external control panel (Rs-232) and
want to make one of the buttons on it select one of the menus to
pull down.

Thanks,
Russ Srole

Russ,

This isn't exactly what you asked for, but using a floating menu might
be close enough for what you want. Anyway, it's the best I could do.

#COMPILE EXE
#DIM ALL
#INCLUDE "win32api.INC"

GLOBAL hDlg AS LONG, hMenu AS LONG, hFileMenu AS LONG, hEditMenu AS LONG
DECLARE SUB addMenu
DECLARE SUB fileMenu
DECLARE CALLBACK FUNCTION dlgProc() AS LONG

FUNCTION PBMAIN() AS LONG
   LOCAL style AS LONG
   style = %WS_SYSMENU + %WS_MINIMIZEBOX
   DIALOG NEW 0, "Test", , , 200, 100, style TO hDlg
   addMenu
   CONTROL ADD BUTTON, hDlg, %IDOK, "&File", 5, 20, 90, 20
   CONTROL ADD BUTTON, hDlg, %IDCANCEL, "&Cancel", 5, 50, 90, 20
   DIALOG SHOW MODAL hDlg CALL dlgProc
END FUNCTION

CALLBACK FUNCTION dlgProc()
   LOCAL x AS LONG, y AS LONG
   SELECT CASE CBMSG
     CASE %WM_COMMAND
       SELECT CASE CBCTL
         CASE %IDOK
            fileMenu
         CASE %IDCANCEL
            DIALOG END CBHNDL
       END SELECT
     CASE %WM_DESTROY
   END SELECT
END FUNCTION

SUB addMenu()
   MENU NEW BAR TO hMenu
   MENU NEW POPUP TO hFileMenu '-----------------------------------
   MENU ADD STRING, hFileMenu, "&Open", 101, %MF_ENABLED
   MENU ADD STRING, hFileMenu, "&Save", 102, %MF_ENABLED
   MENU ADD STRING, hFileMenu, "Save&As", 103, %MF_ENABLED
   MENU ADD STRING, hFileMenu, "-", 0, 0
   MENU ADD STRING, hFileMenu, "E&xit", 104, %MF_ENABLED
   MENU ADD POPUP, hMenu, "&File", hFileMenu, %MF_ENABLED
   MENU NEW POPUP TO hEditMenu '-----------------------------------
   MENU ADD STRING, hEditMenu, "&Cut", 201, %MF_ENABLED
   MENU ADD STRING, hEditMenu, "&Copy", 202, %MF_ENABLED
   MENU ADD STRING, hEditMenu, "&Paste", 203, %MF_GRAYED
   MENU ADD STRING, hEditMenu, "-", 0, 0
   MENU ADD STRING, hEditMenu, "&Select all", 204, %MF_ENABLED
   MENU ADD POPUP, hMenu, "&Edit", hEditMenu, %MF_ENABLED
   MENU ATTACH hMenu, hDlg
END SUB

SUB fileMenu()
   LOCAL n AS LONG, x AS LONG, y AS LONG
   LOCAL pt AS POINTAPI
   pt.x = 0: pt.y = -1
   ClientToScreen hDlg, pt
   n = %TPM_RIGHTBUTTON + %TPM_LEFTALIGN
   TrackPopupMenuEx hFileMenu, 0, pt.x, pt.y, hDlg, BYVAL %NULL
END SUB

You can imitate Alt-... by Keybd_Event.

   #Compile Exe
   #Register None
   #Dim All
   #Include "Win32Api.INC"

   CallBack Function OkButton
      KeyBd_Event %VK_MENU, 0, 0, 0: Sleep 1
      KeyBd_Event &H52, 0, 0, 0: Sleep 1 ' R
      KeyBd_Event &H52, 0, %KEYEVENTF_KEYUP, 0: Sleep 1
      KeyBd_Event %VK_MENU, 0, %KEYEVENTF_KEYUP, 0: Sleep 1
   End Function

   Function PbMain
      Dim hDlg As Long, hMnu As Long, hmnuFile1 As Long, hmnuFile2 As Long
      Dialog New 0, "Menu Test", , , 110, 40, %WS_CAPTION Or %WS_SYSMENU To hDlg
      Control Add Button, hDlg, 101, "Press", 5, 5, 100, 15 Call OkButton
      Menu New Bar To hMnu
      Menu New Popup To hmnuFile1
      Menu Add String, hmnuFile1, "&Load", 1, %MF_ENABLED
      Menu Add String, hmnuFile1, "&Save", 2, %MF_ENABLED
      Menu Add Popup, hMnu, "&File", hmnuFile1, %MF_ENABLED
      Menu New Popup To hmnuFile2
      Menu Add String, hmnuFile2, "&Compile", 3, %MF_ENABLED
      Menu Add String, hmnuFile2, "&Debug", 4, %MF_ENABLED
      Menu Add Popup, hMnu, "&Run", hmnuFile2, %MF_ENABLED
      Menu Attach hMnu, hDlg
      Dialog Show Modal hDlg
   End Function

Thanks for the quick reply, guys. I'll give it a try.

That works great. I had tried it before, but did not know
that you have to do a press and release for each step of the
way.

Thanks again,
