[fpc-pascal] TThread descendant with public events
Hi, What is the rules regarding a TThread descendants and public events. I created a thread that has OnXXX events. These events are triggered in the Execute method of that event. Now my main event (which manages the application GUI) hooked into these event by implementing event handlers. Those event handlers take the data from the event and updates a StringGrid. Is this safe to do? Must the thread execute the event via a Synchronize() call, or is it now needed? The reason I'm not sure here, is because the thread doesn't actuall update the GUI component (stringgrid in this example) directly, it just triggers the event.

Hi, I need to write a data conversion app. Has anybody read MDB data under Linux yet, using SqlDB? I saw there was a ODBC database component, and searched by Ubuntu repository.

First, it's better to use a reasonable (= large enough) buffer size. Second, the simplest approach implying reading line by line and searching using Pos() obviously isn't sufficient for searching across line breaks, i.e. you either need to handle that yourself, or use some unit providing such functionality.

I see, but that means that Marco's comment applies - conversion of PDF files to pure text will probably require more time than finding your string within the (converted) text file.

I don't have any specific one in mind, I just wanted to point out that you need to take care about that. Personally, I'd probably use my unit Buffered (http://www.volny.cz/xhajt03/buffered.zip) and handle the part related to spanning of text across lines myself if relevant (obviously, that depends on your use case), but I'm sure that there are more complete solutions for your needs readily available too; my comment was just to signalize that "Pos" mentioned by Marco may not be sufficient by itself. BTW, to answer your other e-mail too - I don't know about solutions for searching within PDF files directly, I'd also use the external converter myself.

Re: [fpc-pascal] Text scan in text files - (was: Full text scan - PDF files)
Sorry, I agree. But as I search for text within PDF files? I assumed true the following statement of yours... [Somebody can help me please? I need to search strings in Text files using just FPC.] so I suggested the fast-enough (in my opinion) use of the Pos function. If _now_ you want to search directly in the PDFs, then I cannot help you, as I myself would go for the conversion to text files on first instance. TTYTT, I usually search for text in PDFs (using Acrobat Reader, just searching, when I need to convert some e-books) and I see it's blooody slow, compared to a search in a plain text file. I doubt (but also would like to be discredited here...) there is a faster library than the Adobe Acrobat Reader one itself, so I think the combination of the two methods (conversion, and then search) would bring to the same overall speed; if not higher... Just my last 2c on the thing. P.S. Why don't you give it a try, cronometer at hand, first? ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

I'll try this method too. Now, I'm trying to convert the PDF files as best I can...

Search an string in a pdf directly is far away from trivial, you need at least a parse.r and a decompressor. The decompressor is not a problem usually as most files have streams compressed with zlib, but the parser is very complex, locate the text zones is easy (more or less) but if the strings have international characters, it implies the use o CMAPs which is a nighmare. So if you are looking for ASCII words, use PDF2Text and use the POS function over the result: function HaveString(Filename: String; TheString: string): Boolean; var F: TFileStream; S: String; AtPos: integer; begin Result:=false; F:=TFileStream.Create(Filename,fmOpenReadOnly); SetLength(S,F.Size); if F.Size>0 then begin F.ReadBuffer(S[1],F.Size); AtPos:=Pos(UpperCase(TheString),S); if AtPos>0 then Result:=true; end; F.Free; end; -- Best regards, José ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Re: [fpc-pascal] Text scan in text files - (was: Full text scan - PDF files)
Hi, I don't know the PDF file format at all, but I would guess if you look at the many pdf-to-text conversion tools, you will see what they have done. In all likelihood, those conversion tools will be written in C, which you will have to translate to Object Pascal - but that is normally not a difficult task, just a boring task.
