How to compare two PDFs using Visual Basic

Hi,
We have created one Visual Basic exe for comparing two PDFs.We are using AcroExch.App and AcroExch.avDoc
for creating adobe application object. And we are using MenuItemExecute "DigSig:ToolsDiff" for comparing the PDFs. This piece of code is working fine with Adobe 4.0 and it is comparing the PDFs and showing the mismatches.
But the same piece of code is not working with Adobe 8.0 Professional. Is there any similar command to MenuItemExecute "DigSig:ToolsDiff" in Adobe 8.0 to find out the mismatches or any alternate approaches that i can try to make the existing code works properly to see the mismatches between two PDFs.
Thanks in advance,
Raju

The only APIs for comparing PDFs are part of the plugin APIs, and not exposed to COM/IAC. You would need to write a custom plugin that called the APIs directly and then expose your plugin for use via VB.

To compare two pdfs using version 8

Hi,
Can somebody please help me in how to compare two pdfs using acrobat reader ver 8 or any other othe tool which can be used for this. I know acrobat reader 9.0 can do that but i don't want to go for it.
Thanks in advance
Shruti

There is no product called Acrobat Reader any more.
There is the free product Adobe Reader. This cannot compare documents,
in any version.
There is the commercial product Acrobat. This comes in versions
Acrobat Standard and Acrobat Professional. Acrobat Professional can
compare documents, perhaps Acrobat Standard too. This is true in
version 8 and version 9.

Comparing two PDFs using Compare Documents utility in Acrobat Pro in command line

I have a need to compare two PDFs based on text, images, annotations, formatting, headers/footers, styles etcetera. The Adobe acrobat pro tool is working very good as per my requirements. I need to call it through Java program or command line. It could be something which takes the two PDFs as argument and compare options as Pro version have - text, images, annotations, formatting, headers/footers and background and generates the list of differences. It could return the differences either in a form of pdf document highlighting the differences or the map which is mapping something like page numbers to the details of differences that are appearing.
This would be very helpful. Please answer asap.
Thanks in advance.

Sounds like you want to do this on a server, but you should know that Adobe Acrobat cannot legally be used on a server.
For server-based PDF operations you can look at Adobe LiveCycle products or our Adobe PDFLibrary (available in both Java and C++)

How to compare two files using MD5?

Hi,all:
How to compare two files to know if they're the same without any difference?I want to use MD5, but I just konw how get a message digest of a string. How to get a message digest of a file? Or there is other method to compare two files?
Thanks advance!

This is starting to sound rather a lot like a homework problem.
An MD5 message digest is simply a 16 byte array. To compare two message digests...
byte[] md5incoming = ...
byte[] md5comparison = ...
if( md5incoming.equals(md5comparison) ) {
System.out.println("MD5 Checksums match");
}To find out how to generate an MD5 checksum, please look up MessageDigest in the API documentation, and do a google search for "MD5 java"
In a networked scenario, there are two issues - firstly the performance in sending copies of files all over the place (imagine if it's a 10Gb file to be compared over a 14.4K modem link, this would take a while). Secondly, the network link itself might insert an error in the file and you'd get a false miss.
By only sending MD5 digests over the link, you simultaneously reduce the error (shorter files are less likely to be corrupted) and reduce the transmission time (16 bytes takes practically no time to transmit over damp string, let alone any sort of sensible device).

Compare two pdf files using adobe acrobat through command line

Does anyone know how to compare two pdf files using adobe acrobat through command line. I want to do this via command line because we want to compare hundreds of file every day through some automated windows tasks.
If command line option is not available in acrobat, then is it feasible to make use of acrobat javascript API to do this task?
Any kind of help will be greatly.

Command-line: Not possible.
JavaScript: Possible, but very limited. Basically the only thing you can do is simulate clicking the Compare Documents button. The rest has to be done manually.
However, it *might* be possible to automate this process a bit more using a plugin. Ask over at the Acrobat SDK forum for more information...

How do I open a pdf stored in a Microsoft Access database using Visual Basic studios 2012

Currently I am unable to find a valid method of being able to open a pdf stored in a Microsoft Access database using Visual Basic studios 2012. I've tried displaying the entire database on a form, but when I do this all the other columns show up with
the correct data besides the one containing the pdf's, it just displays <binary data> in each row down the column. I also tried another method with which you use the database as a dataset and can drag and drop the rows and columns into the form, which
again works for all the other columns besides the one containing the pdf's but this time I'm unable to interact with the column at all.
Not too sure if this is in the correct place, but any answers or help would be appreciated. Cheers.

Alex,
This forum is dedicated to Project and Project Server. You might get better response, if you post to a Visual Basic forum. Here are couple I could find.

Can I use Visual Basic to covert form user data from multiple .pdf files to a single .csv file?

Can I use Visual Basic to covert form user data from multiple .pdf files to a single .csv file? If so, how?

You can automate Acrobat using IAC (InterApplication Communications), as documented in the Acrobat SDK. Your program could loop through a collection of PDFs, load them in Acrobat, extract the form data from each, and generate a CSV file that contains the data.
Acrobat can also do this with its "Merge Data Files into Spreadsheet" function, but this is a manual process.

How to programmatically compare two PDF documents.

We are in need of a solution related to comparing baselined and revised PDF documents, generally around 2-3 pages of content. Please note that I am looking for programatic comparison, ideally a dotnet based solution using Acrobat SDK. Any help will be highly appreciated.

Is there any recommendation considering there are no ways to programmatically compare two PDF's in .net. I noticed there are few solutions on Adobe site just like below but everyone seems to be stuck at the compare screen unable to simulate the Enter Key functionality.
      AcroAppClass acroApp1 = new AcroAppClass();
            acroApp1.Hide();
            AcroPDDocClass acrpDoc1 = new AcroPDDocClass();
            acrpDoc1.Open("c:\\MoreInformation.pdf");
            acrpDoc1.OpenAVDoc("BaseLine");
            AcroAppClass acroApp2 = new AcroAppClass();
            acroApp2.Hide();
            AcroPDDocClass acrpDoc2 = new AcroPDDocClass();
            acrpDoc2.Open("c:\\MoreInformation1.pdf");
            acrpDoc2.OpenAVDoc("Revised");
            AcroAVDoc avDoc = new AcroAVDoc();
            AcroAppClass acroMainApp = new AcroAppClass();
            acroMainApp.MenuItemExecute("DIGSIG:CompareDocuments");
            avDoc = (AcroAVDoc)acroMainApp.GetActiveDoc();
            Acrobat.CAcroPDDoc acrpDiffDoc = (Acrobat.CAcroPDDoc)avDoc.GetPDDoc();
            bool save = acrpDiffDoc.Save((short)PDSaveFlags.PDSaveFull, "c:\\compared.pdf");

Several of the CWDAQ objects have Device (the device number), DeviceName, and DeviceType properties that I think will give you the information that you're looking for. For more information, look in the index of the Measurement Studio reference for Device, DeviceName, and DeviceType.

How to compare two rows in PL/SQL?

Hi All,
How to compare two rows in PL/SQL? Is there any method that I can use instead of comparing them column by column?
