ListView

If the Options parameter is blank or omitted, all the text in the control is retrieved. Each row except the last will end with a linefeed character (`n). Within each row, each field (column) except the last will end with a tab character (`t).

Specify for Options zero or more of the following words, each separated from the next with a space or tab:

Note: Some applications store their ListView text privately, which prevents their text from being retrieved. In these cases, ErrorLevel will usually be set to 0 (indicating success) but all the retrieved fields will be empty. Also note that ListView text retrieval is not restricted by #MaxMem.

Upon success, ErrorLevel is set to 0. Upon failure, it is set to 1 and OutputVar is made blank. Failure occurs when: 1) the target window or control does not exist; 2) the target control is not of type SysListView32; 3) the process owning the ListView could not be opened, perhaps due to a lack of user permissions or because it is locked; 4) the ColNoption specifies a nonexistent column.

To extract the individual rows and fields out of a ListView, use a parsing loop as in this example:

ControlGet, SelectedItems, List, Selected, SysListView321, WinTitle
Loop, Parse, SelectedItems, `n  ; Rows are delimited by linefeeds (`n).
{
    RowNumber := A_Index
    Loop, Parse, A_LoopField, %A_Tab%  ; Fields (columns) in each row are delimited by tabs (A_Tab).
        MsgBox Row #%RowNumber% Col #%A_Index% is %A_LoopField%.
}

On a related note, the columns in a ListView can be resized via SendMessage as shown in this example:

SendMessage, 4126, 0, 80, SysListView321, WinTitle  ; 4126 is LVM_SETCOLUMNWIDTH.
S↓

In the above, 0 indicates the first column (specify 1 for the second, 2 for the third, etc.) Also, 80 is the new width. Replace 80 with -1 to autosize the column. Replace it with -2 to do the same but also take into account the header text width.

ListBox, ComboBox, DropDownList

All the text is retrieved from the control (that is, the ListView options above such as Count and Selected are not supported).

Each item except the last will be terminated by a linefeed character (`n). To access the items individually, use a parsing loop as in this example:

ControlGet, Items, List,, ComboBox1, WinTitle
Loop, Parse, Items, `n
    MsgBox Item number %A_Index% is %A_LoopField%.

I really need to read the text in a ListBox. My script is as follows:
#x::
SendMessage, 0x189, 2, 0, WindowsForms10.LISTBOX.app.0.378734a1, Form1
if ErrorLevel <> FAIL
{
MsgBox, %ErrorLevel%
}

Where 0x189 refers to the following MSDN function:
http://msdn.microsof... ... ettext.asp

at least according to http://www.codeguru.... ... .php/c2771

Anyways... My problem is that this returns the length of the string in the listbox (this is in accordance with the description of LB_GETTEXT on MSDN. My quesiton is how I could retreave the content that lParam is pointing at after this sendmessage function.

The following is a link to an .exe file that made in Visual Studio 2005 beta 2 (hope it works for you), containing the listbox that I am trying to retreave the text from. http://www.translati...ds.com/demo.exe.

Thanks

I really need to read the text in a ListBox.

Have you tried "ControlGet, List"? This is a relatively recent feature that gets a complete list of items from a ListBox, ComboBox, or DropDownList.

Thanks for the replay, Chris.

I have tried the following script:
ControlGet, List, List,, WindowsForms10.LISTBOX.app.0.378734a1, Form1 
Loop, Parse, List, `n
{
MsgBox Item number %A_Index% is %A_LoopField%.
}

Unfortunatelly, I did not receive any output at all. 

While I got a message box saying "5" with the following script:
SendMessage, 0x189, 2, 0, WindowsForms10.LISTBOX.app.0.378734a1, Form1 
if ErrorLevel <> FAIL 
{ 
MsgBox, %ErrorLevel% 
}

5 represents the number of characters in this entry in the list.

ControlGet is only designed to work with standard ListBoxes and ComboBoxes. Yours control seems like a non-standard (custom) control, which might explain why it doesn't work.

Although I'm all out of ideas, I hope you find a solution or that someone else comes along who knows something.

그렇다! Chris 의 말대로라면 ControlGet 은 standard ListBoxes and ComboBoxes 에 디자인된 것이다. (어쨋든 여기서 필자의 요구조건은 충족시키므로 패스!)

더욱 흥미로운 Chris 의 발언들을 살펴보자!

I understand. The control that I am using is the standard one used by Visual Studio 2005 (although, I am using the beta 2 version).

Although I don't know C++ I found the method that would need some adjustments to make it possible to receive the text. Its name is ScriptSendMessage and it is located in Script2.cpp. This method uses the MSDN method SendMessageTimeout (http://msdn.microsoft.com/library/defau ... ettext.asp).

Are there any C++ experts out there that knows how to implement this?

Thanks a lot in advance.

I don't see how any internal changes to SendMessage would help in this case. The "ControlGet List" method I mentioned
earlier already uses LB_GETTEXT internally. If it fails to work on a custom ListBox, you would have to find out what
messages to send to that particular type of ListBox to get the text out of it.

Microsoft Active Accessibility might be able to extract text from many types of custom controls, but I don't know much
else about it yet. 

• 

ControlGet List method 는 내부적으로 LB_GETTEXT 를 사용한다고 되어있다. 그렇다는 것은 DllCall 에 의해서도 충분히 얻어질 수 있다는 것이다!

이와같이 말이다.

LBCount := DllCall("SendMessage", "uint", hIDLB, "uint", 0x18B) ;LB_GETCOUNT

Thank you a lot for your help. I have sent you 10 dollars to your email address to show my appreciation.

I have a far more general question now. Is it in principle possible to extract the text from any listbox or combobox? I understand that i.e. Java programs are build up in a totally different way, so my question is just about the programs that show up as listboxes in AU3_Spy.

I really need to read text from a range of listboxes where the one at http://www.translati...ds.com/demo.exe is an example of one of them. I think that all the listboxes I want to read from have been programmed in Visual Studio.

I have also thought about using OCR technology to "read" the text off the screen, but this is a really dirty way to solve the problem so I hope there are other possibilities.

Thanks again.

Is it in principle possible to extract the text from any listbox or combobox?

Since any custom control can arbitrarily contain the word ListBox or ComboBox in its name, I would have to say "no".
An application can be designed to store its text privately and draw it on the screen only as needed. In such a case, there
would be no external/direct access to the text (other than something fairly difficult such as ReadProcessMemory).

I have also thought about using OCR technology to "read" the text off the screen

This may be the best approach in this case. Here is a nice command line OCR tool that daonlyfreez recently posted:
Optical Character Recognition (OCR) - gocr [CLI] 

Retrieves various types of information about a control.

ControlGet, OutputVar, SubCommand , Value, Control, WinTitle, WinText, ExcludeTitle, ExcludeText
S

Parameters

OutputVar

The name of the variable in which to store the result of SubCommand.

SubCommand, Value

These are dependent upon each other and their usage is described below.

Control

Can be either ClassNN (the classname and instance number of the control) or the control's text, both of which can be determined via Window Spy. When using text, the matching behavior is determined by SetTitleMatchMode. If this parameter is blank, the target window's topmost control will be used.

To operate upon a control's HWND (window handle), leave the Control parameter blank and specify ahk_id %ControlHwnd% for the WinTitle parameter (this also works on hidden controls even when DetectHiddenWindows is Off). The HWND of a control is typically retrieved via ControlGet Hwnd, MouseGetPos, or DllCall.

WinTitle

A window title or other criteria identifying the target window. See WinTitle.

WinText

If present, this parameter must be a substring from a single text element of the target window (as revealed by the included Window Spy utility). Hidden text elements are detected if DetectHiddenText is ON.

ExcludeTitle

Windows whose titles include this value will not be considered.

ExcludeText

Windows whose text include this value will not be considered.

Sub-commands

For SubCommand, specify one of the following:

• List: Retrieves a list of items from a ListView, ListBox, ComboBox, or DropDownList.
• Checked: Retrieves 1 if the checkbox or radio button is checked or 0 if not.
• Enabled: Retrieves 1 if the control is enabled, or 0 if disabled.
• Visible: Retrieves 1 if the control is visible, or 0 if hidden.
• Tab: Retrieves the tab number of a SysTabControl32 control.
• FindString: Retrieves the entry number of a ListBox or ComboBox that is an exact match for the string.
• Choice: Retrieves the name of the currently selected entry in a ListBox or ComboBox.
• LineCount: Retrieves the number of lines in an Edit control.
• CurrentLine: Retrieves the line number in an Edit control where the caret resides.
• CurrentCol: Retrieves the column number in an Edit control where the caret resides.
• Line: Retrieves the text of the specified line number in an Edit control.
• Selected: Retrieves the selected text in an Edit control.
• Style: Retrieves an 8-digit hexadecimal number representing the style of the control.
• ExStyle: Retrieves an 8-digit hexadecimal number representing the extended style of the control.
• Hwnd [v1.1.04+]: Retrieves the window handle (HWND) of the control.

List

Retrieves a list of items from a ListView, ListBox, ComboBox, or DropDownList. For ListView, additional options can be specified.

ControlGet, OutputVar, List , Options, Control, WinTitle, WinText, ExcludeTitle, ExcludeText
S

ListView

If the Options parameter is blank or omitted, all the text in the control is retrieved. Each row except the last will end with a linefeed character (`n). Within each row, each field (column) except the last will end with a tab character (`t).

Specify for Options zero or more of the following words, each separated from the next with a space or tab:

Note: Some applications store their ListView text privately, which prevents their text from being retrieved. In these cases, ErrorLevel will usually be set to 0 (indicating success) but all the retrieved fields will be empty. Also note that ListView text retrieval is not restricted by #MaxMem.

Upon success, ErrorLevel is set to 0. Upon failure, it is set to 1 and OutputVar is made blank. Failure occurs when: 1) the target window or control does not exist; 2) the target control is not of type SysListView32; 3) the process owning the ListView could not be opened, perhaps due to a lack of user permissions or because it is locked; 4) the ColNoption specifies a nonexistent column.

To extract the individual rows and fields out of a ListView, use a parsing loop as in this example:

ControlGet, SelectedItems, List, Selected, SysListView321, WinTitle
Loop, Parse, SelectedItems, `n  ; Rows are delimited by linefeeds (`n).
{
    RowNumber := A_Index
    Loop, Parse, A_LoopField, %A_Tab%  ; Fields (columns) in each row are delimited by tabs (A_Tab).
        MsgBox Row #%RowNumber% Col #%A_Index% is %A_LoopField%.
}
S↓

On a related note, the columns in a ListView can be resized via SendMessage as shown in this example:

SendMessage, 4126, 0, 80, SysListView321, WinTitle  ; 4126 is LVM_SETCOLUMNWIDTH.
S↓

In the above, 0 indicates the first column (specify 1 for the second, 2 for the third, etc.) Also, 80 is the new width. Replace 80 with -1 to autosize the column. Replace it with -2 to do the same but also take into account the header text width.

ListBox, ComboBox, DropDownList

All the text is retrieved from the control (that is, the ListView options above such as Count and Selected are not supported).

컨트롤(개체)로부터 모든 텍스트가 반환되어진다. 즉, ListView의 옵션들 (Count 그리고 Selected 같은 것은 지원되지 않는다)

Each item except the last will be terminated by a linefeed character (`n). To access the items individually, use a parsing loop as in this example:

마지막을 제외한 각각의 아이템들은 Linefeed Character (`n) 문자에 의해서 구분지어진다. 각각의 아이템들에 접근하기 위해, 다음과 같은 parsing loop 를 사용해본다.

ControlGet, Items, List,, ComboBox1, WinTitle
Loop, Parse, Items, `n
    MsgBox Item number %A_Index% is %A_LoopField%.
