Dear AllI have developed a Port Operation System in VFP 9.0. Now the client would like to directly convert electronic versions of shipping manifests (in PDF) to DBF. I would appreciate any assistance to convert PDF to DBF. Thanks in advance HiLooking at this I think the easiest approach maybe to find a PDF to Text converter program that will also operate at a command line level. Then you can call and run from with VFP using either the VFP RUN command calling a batch file, or use ShellExecute to run the command line batch file.
The Basics of Querying in FoxPro with SQL SELECT. To simplify the above as a starting point, the FoxPro command syntax places optional clauses in square brackets. Thus, the most basic form of the command is. The code examples shown here depict the SELECT statements on multiple lines. This is done for ease of reading, and is recommended for.
This would automate the process for you as much as possibly within VFP. Such a PDF to Text converter that operates also at the command line level can be downloaded from this link: Pick to top download item called 'PDF to Text Converter'. Command line usage look like this below: PTConverter output TXT file : Open an existing PDF file to convert.(MUST BE FULL FILE NAME) output TXT file: Write to TEXT file, the default is same filename of input PDF file.(MUST BE FULL FILE NAME) -f : Specify the first page number.
-l : Specify the last page number. -d :Specify the column distance. -b :Add page break. For Example: PTConverter c: PDFS input.pdf PTConverter c: PDFS input.pdf -f 1 -l 12 PTConverter c: PDFS input.pdf c: text Command parameter support wildcard and long file name, if the file name or folder name include space, Please uses quotation marks to around the name.
For example: PTConverter 'C: TEST 1 MYPDF.PDF' 'C: TEST 1 MYPDF.TXT' The register cost of this convert is $35.00 US I actually had a project a couple of years back to so something like you are trying to do only in my case is was employee payrole information that was sent in a PDF file. So I had to extract the PDF into a Text file and then parse out the required infromation.
This was a pain. I guess you know that the coverted PDF file into text will produce a very unstructured file and it becomes very difficult to extract the required data without a complicates parsing.prg written in VFP. Now here is the method I used to get the text file into VFP to start my parsing efforts. I create one VFP table named PDFdata with one character field c(254) called PDFdata.
I then appended the text file into my blank VFP table so now I have each line of the text file occupying one record in my table. Now with the data in a table I could do things like remove all blank lines with a VFP commands like: USE PDFDATATBL GOTO TOP DELETE FOR PDFdata = ' WHILE.NOT.
EOF PACK Finally I had to get down to using a bunch of SUBSTR function at specific location to obtain the data I needed and then write the data into a second structured VFP table with field names to match the data I SUBSTR'ed out. Turned out to be a plus 40 hour conversion job. Not difficult, just tedious. Pete 'the IceMan', from the Great White North of Canada. Dear Pete, You described my problem very accurately.
The shipping agents that work with my client (Gambia Ports Authority) send their manifest in PDF. Once I can extract the text, I will be able to do the necessary string manipulation to update the fields in my application. My only difficultiy is to extract text from PDF. I have recently (May 2011) done a similar job of creating an interface for a Banking software which included a lot of string manipulation.
So that is familiar territory. What my mind tells me I need to do but don't know how to is: 1.
Open a pdf, perhaps using low-level file functions; 2. Decompress it (don't know how); 3. Extract text and send to my character field table. Jibi From the Smiling Coast of Africa Right on the Atlantic Ocean.
