I am trying to automate some non-trivial task* with Adobe's Acrobat XI.
I think the way to go is using Acrobat's IAC, which seems to be well-documented, eg. here.
However, I could not figure out how to access the application object, eg. from within an HTA. I mean: How do I get the app object mentioned in the API documentation?
It feels like I am missing something very obvious. However, I have been searching and trying unsuccessfully for quite a while now.
Alternatively, any other suggestion how to perform complicated stuff (see footnote) in Acrobat is appreciated.
*The task is concatenating 1 to n JPG files into a PDF/A document (like, tens of thousands of times). The mapping is given through a TSV file or something alike. The requirement of generating PDF/A which pass Adobe's validation forces me to use Acrobat, at least for this last step.
Are you using .net? Are you missing a reference to IAC?
try: SET gApp = CreateObject("AcroExch.App")

I've got an Excel file that takes ~10 inputs and outputs ~5 numbers. The problem is, the calculations run involve lots of assumptions, are rather complex, and laid out over 5 excel sheets with lots of lookup tables, etc.
I'd like to wrap the Excel model in an iPad app -- so that it's easy to solicit user input and show the easy outputs without having them to see the dirty work beneath.
It's important for me to encapsulate the Excel model since that's still getting tweaked and adjusted... so to have a wrapper set up as opposed to reproduce the logic in the Excel file would save me probably 2 orders of magnitude of time.
Have looked around and not found a way to do this yet... any thoughts?
Thanks
Two options come to mind.
One is that you can use an excel wrapper on iOS. Details can be found here: How can i create excel sheet and file in iPhone sdk?
The second option is to setup a server and pass the task onto the server. I'm familiar with Ruby, and creating/modifying excel files in Ruby is a breeze. I'd expect PHP, python, etc. to have similar faculties.
Either option is going to depend on your use case, whether you're charging for the app or not, and your familiarity with server side programming.
I want record screen (by capturing 15 screenshots per second). This part I know how to do. But I don't know how to write this to some popular video format. Best option which I found is write frames to separated PNG files and use commandline Mencoder which can convert them to many output formats. But maybe someone have another idea?
Requirements:
Must be multi-platform solutions (I'm using Free Pascal / Lazarus). Windows, Linux, MacOS
Exists some librarys for that?
Could be complex commandline application which record screen for me too, but I must have possibility to edit frames before converting whole raw data to popular video format
All materials which could give me some idea are appreciated. API, librarys, anything even in other languages than FPC (I would try rewrite it or find some equivalent)
I considered also writting frames to video RAW format and then use Mencoder (he can handle it) or other solution, but can't find any API/doc for video RAW data

Argalatyr mentioned ffmpeg already.
There are two ways that you can get that to work:
By spawning an new process. All you have to do is prepare the right input (could be a series of jpeg images for example), and the right commandline parameters. After that you just call ffmpeg.exe and wait for it to finish.
ffmpeg makes use of some dll's that do the actual work. You can use those dll's directly from within your Delphi application. It's a bit more work, because it's more low-level, but in the end it'll give you a finer control over what happens, and what you show the user while you're processing.
Here are some solutions to check out:
FFVCL Commercial. Actually looks quite good, but I was too greedy to spend money on this.
Open Source Delphi headers for FFMpeg. I've tried it, but I never managed to get it to work.
I ended up pulling the DLL wrappers from an open source karaoke program (UltraStar Deluxe). I had to remove some dependencies, but in the end it worked like a charm. The relevant (pascal) code can be found here:
http://ultrastardx.svn.sourceforge.net/viewvc/ultrastardx/trunk/src/lib/ffmpeg-0.10/
There was some earlier discussion with a Delphi component here. It's a very simple component that sometimes generates some weird movies. Maybe a start.
I need to generate a report/printout programmatically.
My app currently uses FastReport to build a report, consisting of text, images, tables etc.
It does not bind to any database. Everything is built programmatically.
However, the finished report does not look the same in PDF and RTF, and the old code is generally very complicated.
Are there any better tools to programmatically make a printout or report? Preferably one that outputs PDF and DOC.
In my opinion you've already got the best! I've used QuickReports, Piparti (early ReportBuilder), Crystal(!) and ReportBuilder and I've written a few reports by sending commands direct to the printer. As far as I'm concerned FastReport is much better (although I haven't tried Rave - nor will I).
Is it a recent version of FR? The PDF output for us is fine.
They have some good examples of writing reports through code on their website I believe and if you're looking at re-writing all the reports in A.N.Other reporting product why not, instead, use the opportunity to re-write the reports in a more maintainable way using FR? (Assuming that's possible, of course). Perhaps a cleaner approach to the code of the report generation will make it easier for the FR converter to create the RTF/DOC output...
I've never had much luck generating decent RTF versions of reports from commercial report writers. The only decent output I got was through lovingly hand coding every report using hundreds of '{','}' and '\' and spending days reading the RTF specs. Never again!
A lot of it appears to be down to the order you add the text/lines/fonts/styles etc to the report and the RTF generator can find it difficult to get the best rendering - I think.
You can try Rave Reports.
It has built in components to generate PDF, RTF and HTML documents.
And also it comes free.
For non-database printing needs, FastReport already works (code-based reporting), but for direct printing of Documents you could consider the very-thorough ExpressPrintingSystem from developer express, which is a true delphi printing system, not a reporting system.
Also if you need to create a print documents, almost like a word processor, and then print those word-processor-like documents, consider TRichView. It supports .DOC files, something you asked about.
Some day you might need a banded-report generator again and if you do, FastReport really is the best.
I need to add printing capabilities to an app and I have been looking around for information about printing. Logical/physical sizes, dpi, font scaling, etc, lots to digest since I never programmed printing into any app before.
Are there any sites that would offer a primer on the topics of page sizes, margins and all the other elements required to understand printing on Windows? I've been looking around for a while but what I find is either cryptic or years old...
I've been playing around with TPrinter, but I would like to build solid printing functionalities and understand what I'm doing better.
Using a report solution is not an option, even though I'm sure it would provide better results much sooner.
Two links to get you started:
Printing with TPrinter
Printing via the TPrinter Canvas
I think that you are looking too lowlevel.
Try looking at the build reporting tools (Rave or whatever is in your product).
Personally i am using a product called Report Builder from Digital Metaphors.
But if you want to do the lowlevel stuff lot og good information can be found at efg's computer lab - printing
Well, I have done things a variety of ways in the past, including the "hard way" with TPrinter. In fact, I recently had to do that again to run a special inventory label printer.
On the other hand, sometimes you are better off taking work others have done and using it for your benefit. I agree that ReportSmith isn't so great, and also it's Delphi (and Windows) specific. Using Excel or Word has those limitations, plus the fact that the user has to actually have them installed.
One thing I have done to make printing easy for some simple applications is just to generate an HTML file and call the user's web browser, then they can print it. HTML tables can be created relatively easily for numerical data, and you can include photos, etc. as well. This works well for some applications, and works on every platform where a web browser is installed. The downside, of course, is that HTML isn't the most precise layout language.
The version of Delphi you´re using is important. A number of Delphis came with print engines like ReportSmith (ugh). Another option thinking laterally is to use MS Word as a print engine. I´ve hooked into instances of Word & Excel before & utilised their functionality. As to raw printing using TPrinter or the print method of TForm you´d have to be pretty desperate. I seem to recall the Pacheo / Texeira Delphi books coming with a pretty good overview so you might want to see if you can find a copy of that somewhere.
What's the best way to set up help (specifically HTML Help) for a Delphi application? I can see several options, all of which has disadvantages. Specifically:
I could set HelpContext in the forms designer wherever appropriate, but then I'm stuck having to track numbers instead of symbolic constants.
I could set HelpContext programmatically. Then I can use symbolic constants, but I'd have more code to keep up with, and I couldn't easily check the text DFMs to see which forms still need help.
I could set HelpKeyword, but since that does a keyword lookup (like Application.HelpKeyword) rather than a topic jump (like Application.HelpJump), I'd have to make sure that each of my help pages has a unique, non-changing, top-level keyword; this seems like extra work. (And there are HelpKeyword-related VCL bugs like this and this.)
I could set HelpKeyword, set an Application.OnHelp handler to convert HelpKeyword requests to HelpJump requests so that I can assign help by topic ID instead of keyword lookup, and add code such as my own help viewer (based on HelpScribble's code) that fixes the VCL bugs and lets HelpJump work with anchors. By this point, though, I feel like I'm working against the VCL rather than with it.
Which approach did you choose for your app?
When I first started researching how to do this several years ago, I first got the "All About help files in Borland Delphi" tutorial from: http://www.ec-software.com/support_tutorials.html
In that document, the section "Preparing a help file for context sensitive help" (which in my version of the document starts on page 28). It describes a nice numbering scheme you can use to organize your numbers into sections, e.g. Starting with 100000 for your main form and continuing with 101000 or 110000 for each secondary form, etc.
But then I wanted to use descriptive string IDs instead of numbers for my Help topics. I started using THelpRouter, which is part of EC Software's free Help Suite at: http://www.ec-software.com/downloads_delphi.html
But then I settled on a Help tool that supported string ID's directly for topics (I use Dr. Explain: http://www.drexplain.com/) so now I simply use HelpJump, e.g.:
Application.HelpJump('UGQuickStart');
I hope that helps.
We use symbolic constants. Yes, it is a bit more work, but it pays off. Especially because some of our dialogs are dynamically built and sometimes require different help IDs.
I create the help file, which gets the help topic ID, and then go around the forms and set their HelpContext values to them. Since the level of maintenance needed is very low - the form is unlikely to change help file context unless something major happens - this works just fine.
We use Help&Manual - its a wonderful tool, outputting almost any format of stuff you could want, doc, rtf, html, pdf - all from the same source. It will even read in (or paste from rtf (eg MSWord). It uses topic ID's (strings) which I just keep a list of and I manually put each one into a form (or class) as it suits me. Sounds difficult but trust me you'll spend far longer hating the wrong authouring tool. I spent years finding it!
