"Visible Text", once more...BUT with calc.exe

[capitanves]

Hi, I am a newbie.

My task is to read the display value in calc.exe. I use AutoItInfo for getting oriented. 

What I see is:

1-The display value is contained under the tab "Visible Text"

2- The display control has the property text= nothing

3-The CalcFrame window has the property text =nothing

 

The main question is:

1- How can I get the text from calc display? Why Can't I get the "visible text" from of the windows?

 

Here the code I used

Thank you guys for the support :-)

#include <Constants.au3>



Local $strCalcClass = "[CLASS:CalcFrame]"

Run('calc.exe')
; Wait for the calculator to become active. The classname "CalcFrame" is monitored instead of the window title
$hCalcWnd = WinWaitActive("[CLASS:CalcFrame]")

; Now that the calculator window is active type the values 2 x 4 x 8 x 16
; Use AutoItSetOption to slow down the typing speed so we can see it
AutoItSetOption("SendKeyDelay", 10)
Send("2*4*8*16=")
Sleep(200)
WinWait("[CLASS:CalcFrame]")
ConsoleWrite('Ciccio franco va in vacanza'& @CRLF)
; this "works" in the sense that, in spite of what I see, AutoInfo says that there is
; no text in the contro
Local $myText = ControlGetText($hCalcWnd, "", "[CLASS:#32770; INSTANCE:1]")

; this works nicely
Local $strButton = ControlGetText($hCalcWnd,'', '[CLASS:Button; INSTANCE:29]')

; does not work
Local $strWinText = WinGetText('ACTIVE')

ConsoleWrite('====> mhCalcWnd=' & $hCalcWnd& @CRLF)
ConsoleWrite('====> Control Text=' & $myText& @CRLF)
ConsoleWrite('====> Window Text=' & $strWinText & @CRLF)
ConsoleWrite('====> Button Text=' & $strButton & @CRLF)

I'm not sure of the reason, but some custom controls can be tricky. This is a work around which seems to work with calc.exe but the method used is unlikely to work with other programs in similar situations (not so often at least without modification).
 

#include <Constants.au3>
#include <StringConstants.au3>

Local $strCalcClass = "[CLASS:CalcFrame]"

Run('calc.exe')
; Wait for the calculator to become active. The classname "CalcFrame" is monitored instead of the window title
Local $hCalcWnd = WinWaitActive($strCalcClass)

; Use AutoItSetOption to slow down the typing speed so we can see it
AutoItSetOption("SendKeyDelay", 10)

; Now that the calculator window is active type the values 2 x 4 x 8 x 16
Send("2*4*8*16=")
Sleep(200)

Local $myText = StringStripWS(WinGetText($strCalcClass, ""), BitOR($STR_STRIPLEADING, $STR_STRIPTRAILING))

ConsoleWrite('====> mhCalcWnd=' & $hCalcWnd& @CRLF)
ConsoleWrite('====> Control Text=' & $myText& @CRLF)

I imagine someone will post a better solution. There ought to be one and I would like to know what it is myself. In any case you are unlikely to need calc.exe since there are a variety maths functions available in AutoIt which will suffice in most situations.

Edit : The forum highlighting has gone nuts.
