WinTask 3.5   Introducing OCR functions

May 2008

Three new OCR functions have been added (not available in WinTask Lite):

• CaptureOCR$, captures what is seen in the specified window, OCRizes the content and returns the text as analysed by the OCR engine
• CaptureAreaOCR$, captures what is seen in the specified area of the specified window, OCRizes the content and returns the text as analysed by the OCR engine
• UseOCREngine, specifies which OCR engine will be used by subsequent OCR function calls

How works OCR: WinTask can now use two different OCR engines. Our internal one is delivered with our software but is not accurate when a big rectangle has to be OCRized. All our OCR functions can use now the OCR engine delivered with Microsoft Office 2003 or 2007. When an OCR function is called, WinTask checks first if a UseOCREngine line exists in the script above the call. If such a line is there, the OCR function uses the specified OCR engine. If no UseOCREngine is used in the script, the OCR functions use our internal OCR engine.
If you have Office 2003 or 2007 and do not know if Office OCR engine is installed on your PC, you can look at How to install Office OCR engine help topic.

The new Encrypt function encrypts a string (not available in WinTask Lite).
An additional optional parameter, a timeout, has been added to MsgBox function: if after the specified timeout, no button has been clicked, the msgbox dialog box vanishes.
MsgFrame function has been redrawn in order to display a small rectangle around the displayed text instead of a blue empty title.

WinTask 3.5 had been built with a new version of InstallShield, a new version of the Compiler and a new version of Visual Studio. Those new versions have needed a re-writing of string management, and impacted External function.
VERY IMPORTANT: if you want to run scripts built with previous versions of WinTask, you have to recompile them using WinTask 3.5 version.


The minor fixes included in version 3.5 are listed below:

• GetFrameSource$ and CaptureHTML do not crash anymore IE when a lot of data are on the page
• Capture$ was not capturing a text when it was a one-line text displayed at the top left of the window
• DateToDate function was not working properly with negative intervals
• TaskEdit does not crash anymore when switching from a Unicode script to an ANSI script
• A data exchange memory zone was not freed properly with virtual memory decreasing slowly
• WriteExcel returns now a -3 error code if it tries to write to an opened Excel file
