Passing keyboard command to another application 2

[LuigiG]

I have an application that runs in an industrial computer without keyboard. The application performs a do while loop that stops if you click on the F5 key. The screen is small and you can not use the virtual keyboard of windows.
I created an app with a button that sends the command F5. This is the code but does not work ,the application passes in the foreground but the Keyboard command does nothing any ideas how to solve

DECLARE INTEGER FindWindow IN win32API STRING @ cClass, STRING @ cTitle
DECLARE LONG BringWindowToTop IN Win32API LONG
nhwnd=FindWindow(0,"Lettura sensori")
BringWindowToTop(nhwnd)
KEYBOARD "{F5}"

Thank you
Luigi

The KEYBOARD Command only sends keys to the current Foxpro Application, Bringing a Window to the top does not change that.

What you could try is using WSHShell:

o = CreateObject("WScript.Shell")
o.SendKeys('abc',0)

The WSHShell SendKeys() method sends keys to the active window.

Just to add to Olaf's explanation ...

You still need to bring the window to the top. o.SendKeys will send the keystroke to the active window.

To send F5:

o.SendKeys('{F5}')

Correct Mike, that code simply is the replacement code for the KEYBOARD "{F5}" Command. I'd first try with abc to a notepad window for example, and then go for {F5}. In regfard to the MSDN that is the correct syntax, as in Foxpro.

Bye, Olaf.

The comand works in my application if I use any keyboard letter for example o.SendKeys('x'),if I use o.SendKeys('{F5}') it works in notepad but not in my application I do not know why?

Thank you for your help

Can't tell you either, sorry. If that doesn't work out you could try to use the SendMessage API call to send Windows Messages as WM_KEYDOWN and WM_KEYUP.

Bye, Olaf.

No, we can't tell you why F5 doesn't work in your program. We don't know how your program is supposed to react to F5.

Ar you sure that your program is the active window when you issue F5?

Also, you don't need to use SendKeys within a FoxPro application. You can use KEYBOARD in that case.
