Textract Problem
Question:
I have a script that starts to process and then I receive a message thatWINBATCH.EXE HAS GENERATED ERRORS AND WILL BE CLOSED BY WINDOWS. AN ERROR LOG IS BEING CREATED.
I do not know where to look for the error log.
I have been experiencing problems running this script since yesterday. I honestly think that I hosed something up when I manually terminated the script.
The script is using TEXTRACT to screen scrape from a window driven by Java. I am using ObjectOpen to open TEXTRACT. The script was at the point of doing a screen scrape using a loop. I realized that I had something incorrect and that I would not exit the loop,so I manually terminated the script. There has been funky stuff happening since then.
Any guidance would be appreciated. Thanks.
Answer:
First try rebooting the system. If that doesn't help then we need to determine exactly where in the script it is crashing. Add DebugTrace to the beginning of the script and run it until it crashes. The last line written to the trace file was the last sucessfully executed line. This means the next line in the script is the line that casused the script to crash. What is that line?User Reply:
The DebugTrace file indicates that the script seems to be crashing on the line:rc = Txtr.ReadScreen(200,600,750,750)
Answer:
This maybe due to a problem with Textract OLE Object. Textract support:support@structurise.com.Althought I tested the following code on my XP system and was unable to get it to GPF (Crash).
BoxOpen("ReadSCreen - Hold Shift Key Down to Exit Script","")
Txtr = ObjectOpen("TxtrCtl.TxtrCtl")
rc = Txtr.Init
While @True
if iskeydown(@Shift)
ObjectClose(Txtr)
exit
endif
rc = Txtr.ReadScreen(0,0,750,750)
scrnprnt = Txtr.Text
BoxText(scrnprnt)
Timedelay(0.5)
EndWhile
ObjectClose(Txtr)
What happens if you run the attached code?
User Reply:
That script worked ok! So I do believe that the problem is with Textract. I have sent an email to the support site..... I do believe that I have resolved the issue of the WINBATCH failure.Simply, I made several programming errors.
-
I did a test where:
- I had Notepad open with some lines displayed that did not change.
- Created a script to perform a loop about 20 times to screen scrape using TEXTRACT from that Notepad display.
- I used the READSCREEN command from TEXTRACT and dumped the results to a variable.
What I think happened is that I used up some type of memory. So I went back to the documentation for TEXTRACT and noticed that there is a TERM command that frees up resources.
I modified my test by doing the following each time that I executed the loop:
ObjectOpen for Textract The Textract INIT command The Textract READSCREEN command The Textract TERM command ObjectClose for TextractThe test ran no problems. So I modified the original script that I was having a problem with and made the following changes:
- Use a counter to control the maximum
number of types that a loop can execute to
avoid an infinite loop incase of an error
on my part.
- Added the ObjectOpen, INIT, TERM and ObjectClose each time that I invoke TEXTRACT.
- In TEXTRACT there is the TERM command that frees up resources
