How to obtain textual contents from a window

Question

I have a window that displays a book. In two smaller boxes below, there is page number and volume information of the book that is open. I can get that information easily as follows:

ControlGetText, volume, ThunderRT6TextBox3      
ControlGetText, page, ThunderRT6TextBox2

Then my script makes my mouse pointer move to a button. It clicks it, and a new window pops open. In that window, there is more textual information related to the book, such as publisher, name author, edition etc. I want to retrieve that information. But when I try the same strategy it is not working, eg:

ControlGetText, data, RichTextWndClass3

The only difference between the two cases, is that those two small boxes are editable, you can enter text whereas this window is static.

I tried many other options such as: SendEvent ^a Which is equivalent to control + a, which should select everything. I tried putting pauses but it would never select. I tried the script to manually double click on that window. It works, and one word gets select like that. Even then SendEvent ^a doesn't do anything. However, if I do SendEvent ^{insert}, then the selected word gets copied to my clipboard.

I experimented with more combinations:

ControlSend ahk_class ThunderRT6FormDC, ^a
ControlSend ClassNN RichTextWndClass3, ^a

and

ControlSend ThunderRT6FormDC, ^a
ControlSend RichTextWndClass3, ^a

None of them work. All text selection does not manifest itself in that window.

The only alternative remaining for me is to make the script do a manual selection of the entire text. However, this is slow and very ridiculous. Moreover, in Window Spy under the section: Visible Window Text, the text is all there. I tried many other possibilities and I am at the end of my wits. How am I to harvest that text directly?

EDIT-- The text of the window shows in Window Spy under the heading: TitleMatchMode=slow Visible Text, NOT the heading: Visible Window Text

EDIT-- I spoke to you about two windows. The first one in which i get volume and page number. The second one which needs to pop up by pressing a button. Both these windows have the same class-name: ahk_class ThunderRT6MDIForm Is that problematic in any way?

---

EDIT-- The conclusion is that it is impossible for me to get that text from the second window directly. As such, I opted for the lame, boring manual method. I send out a {shift down} to the active window and then do a click at the bottom of the window. Then I save the selection to my clipboard. It works, but it is just stupid. Please help me find a more elegant solution than this one.

This is the code I used:

ControlGetText, volume, ThunderRT6TextBox3 

ControlGetText, page, ThunderRT6TextBox2 

Click, 110, 70 

sleep 1000

SendInput {shift down}

click 29, 490

SendInput {shift up}

sleep 1000

SendInput, ^{ins} 

sleep 100

It is funny to note that real keyboard keys, such as a b c are not possible. But I am able to send a ctrl, shift and an ins. As I noted above, ^c was also giving issues just like ^a was giving issues.

Answer 1

There is an autohotkey script that emulates most of the window spy logic. It is called AHK_Window_Info_v1.7.ahk. The nice thing is... you can run it to see if your second window text if visible to this script and if so... the logic needed to pull the information is available inside the script. Here is a link to the webpage and the script is available through SKANs dropbox link on that page. http://www.autohotkey.com/board/topic/8204-ahk-window-info-17/

This routine will do the job of getting and returning from the active window the following text sections: - EdtWindowTextFastVisible - EdtWindowTextSlowVisible - EdtWindowTextFastHidden - EdtWindowTextSlowHidden

MyGetWindowText(ByRef EdtWindowTextFastVisible, ByRef EdtWindowTextSlowVisible, ByRef EdtWindowTextFastHidden,ByRef EdtWindowTextSlowHidden)
{
; Source: https://code.google.com/p/autohotkey-cn/source/browse/trunk/Source/AHK_Window_Info/AHK_Window_Info_v1.7.ahk?r=6
EdtWindowTextFastVisible =
EdtWindowTextSlowVisible =
EdtWindowTextFastHidden =
EdtWindowTextSlowHidden =

WindowControlTextSize = 32767
VarSetCapacity(WindowControlText, WindowControlTextSize)
WinGet, WindowUniqueID, ID, A

    If not DllCall("GetWindowText", "uint", A_LoopField, "str", WindowControlText, "int", WindowControlTextSize)

        If (WindowControlStyle & 0x10000000)
        { ; Control is visible vs. hidden (WS_VISIBLE).
            If text_is_fast
            EdtWindowTextFastVisible = %EdtWindowTextFastVisible%%WindowControlText%`r`n
            Else
            EdtWindowTextSlowVisible = %EdtWindowTextSlowVisible%%WindowControlText%`r`n
        } Else
        { ; Hidden text.
            If text_is_fast
            EdtWindowTextFastHidden = %EdtWindowTextFastHidden%%WindowControlText%`r`n

;EdtWindowTextSlowHiddenFull := ShowOnlyAPartInGui("EdtWindowTextSlowHidden", EdtWindowTextSlowHidden, 400)

Return
}
