Here is a sample of reading text from a PDF using ITextSharp[^]: ...

let args = System.Environment.GetCommandLineArgs() if args.Length <= 2 then let exe = Path.GetFileName(args.[0]) eprintfn "Usage: %s dir pattern" exe exit 1 let directory = args.[1] let pattern = args.[2] for fileName in Directory.GetFiles(directory, pattern) do // Open a file stream for the file name use inputReader = File.OpenText fileName // Create a lex buffer for use with the generated lexer. The lex buffer // reads the inputReader stream. let lexBuffer = Lexing.LexBuffer<_>.FromTextReader inputReader // Open an output channel let outputFile = Path.ChangeExtension(fileName,"html") use outputWriter = (new StreamWriter(outputFile) :> TextWriter) // Write the header fprintfn outputWriter "<html>\n<head></head>\n<pre>" // Run the generated lexer Text2htmllex.convertHtml outputWriter lexBuffer // Write the footer fprintfn outputWriter "</pre>\n</html>\n" main() You can produce an F# source file from the previous lexer definition by running the following command at the Windows command prompt: fslex text2htmllex.fsl --unicode This produces text2htmllex.fs, which contains the implementation of the lexer convertHtml. This lexer is imperative, in that it prints to an output stream instead of returning tokens. The signature of the entry point to the generated lexer is as follows: val Text2HtmlLex.convertHtml: System.IO.TextWriter -> Lexing.Lexbuffer<char> -> unit You can now compile the driver and the lexer together: fsc text2htmllex.fs text2html.fs r FSharp.PowerPack.dll You can run the resulting program as follows, giving a source directory and a file pattern and producing an .html version of each file that matches by applying the HTML conversion: text2html . *.txt

Initially, I wrote all the hook functions so that they were just pass-through functions and called the real functions directly This approach worked great Then I put the parameters and the return value for the functions into local variables Getting the value returned from the real function was simple, but because I started implementation of DeadlockDetection with Visual C++ 6, I didn't have a clean way to get the return address in my C/C++ hook function Visual C++ NET now offers the _ReturnAddress intrinsic, but that was not available in Visual C++ 6 I needed the DWORD right before the current stack pointer Unfortunately, in straight C/C++, the function prolog would've already done its magic by the time I could get control, so the stack pointer would've already moved away from where it needed to be.

You might think that the stack pointer is just offset by the number of local variables, but that isn't always the case The Visual C++ compiler does an excellent job of optimizing so that the stack pointer isn't in the same place with different optimization flags set Although you might declare a variable as a local variable, the compiler can optimize the variable by storing it in a register so that it doesn't even appear on the stack I needed a guaranteed way to get the stack pointer no matter what optimizations were set At this point, I started thinking naked (no, not me without clothes): why not declare the hook functions as __declspec(naked) and create my own prolog and epilog code With this approach, I'd have complete control over ESP no matter what optimization settings were used.
