Unfortunately, GrabText probably cannot extract text that is purely based
on an image (e.g., a captcha). The TextGrab SDK library determines what
characters are present based on fonts installed on the system.

Many bug fixes and feature enhancements have been made since the last
release. Besides the command line and dialog interfaces, GrabText is
now a COM server as well. It may be instantiated by almost any COM
automation client using the "Grab.Text" ProgID. At the end of the
installation process, checkboxes offer options to install JAWS or
Window-Eyes script packages that demonstrate this COM server in
Notepad. Another checkbox will open Notepad with a demo file containing
a few lines of text.
Position the caret and mouse pointer on different parts of the text.
Then press F1 to initialize the GrabText object, and F2 through F8 to
grab different areas of text. F9 grabs them all and copies the result
to the clipboard so you can paste and examine it. Also try other
dialogs of Notepad that have more controls, e.g., the file open
dialog. Press
Shift+F1 to close the GrabText object.
The GrabText installer puts a COM server in the Global Assembly Cache
(GAC) of the .NET Framework. To instantiate it as a COM object, pass
"Grab.Text" as a parameter to the CreateObject function, or
equivalent, of the programming language you are using. Methods of the
object are listed in the documentation excerpt below, grouped into the
following categories:
grab, window handle, window coordinate, point coordinate, directory,
and miscellaneous. The initial letter of a variable name indicates
its data
type: boolean, integer, string, or general variant.
Please note that, although the current demos use screen reader
scripting languages, the text is extracted from the screen in a manner
completely independent of the screen reader in use.
Grab methods:
sText = GetTopLevelWindowText(iHandle) sText = GetActiveWindowText()
sText = GetFocusControlText() sText = GetMouseControlText() sText =
GetControlTextFromHandle(iHandle) sText = GetControlTextFromPoint(iX,
iY) sText = GetRectangleText(iLeft, iTop, iRight, iBottom) sText =
GetCaretClip() sText = GetMouseClip() sText = GetClip(iX, iY) sText =
GetCaretCharacter() sText = GetMouseCharacter() sText =
GetCharacter(iX, iY)
Window handle methods:
iHandle = GetActiveWindow()
iHandle = GetFocusControl()
iHandle = GetOwnerWindow(iHandle)
iHandle = GetTopLevelWindow(iHandle)
iHandle = GetParentWindow(iHandle)
Window coordinate methods:
iX = GetWindowLeft(iHandle)
iY = GetWindowTop(iHandle)
iX = GetWindowRight(iHandle)
iY = GetWindowBottom(iHandle)
Point Coordinate methods:
iX = GetCaretX()
iY = GetCaretY()
iX = GetMouseX()
iY = GetMouseY()
Directory methods:
sDir = GetProgramDir()
sDir = GetDataDir()
sDir = GetNETDir()
Miscellaneous methods:
bValid = Init(sUserName, sLicenseKey)
sName = GetWindowName(iHandle)
bFound = IsScreenReaderActive()
bSpoke = Say(vText)
bResult = SetActiveWindow(iHandle)
