@Looking

What criteria do you have for the resulting text file?

How was the PDF created?  -- The possible solutions differ.

Here's the German->English translation, via Google Translate, of the comments:

So now I've finally found a solution how to
 the entire text from a PDF file (also possible with multiple pages)
 can read.
 I have been in the same time vorherein for my dirty
 Programming apologize, but I hope you can still what
 to start! The form includes a TMemo, 5 TLabel, TButton 1
 and an open dialogue

 oh yes, you have to insert before or a type library
 opens to the type library import dialog (project
 ) And find the folder when adding Selects Adobe Acrobat.
 There you should find a file named Acrobat.tbl, if not then
 Just look for times.
 Now for the install and then applying unit ready.
 have fun

I, personally, have not tried this.

@Looking

If the PDF only has an image layer, then there is an extra step required to recognize the characters/words in the image and add a text layer to the PDF.  People make this mistake when they convert TIFF images to PDFs and then wonder why they don't find anything when they do an Adobe search for words.

Did you look at the PDFText utility?

For some reason, I'm only seeing XPDFText at that site.  I'll look for the free PDFText utility.

I'm pretty sure that I got my utility from foolabs.  The README documentation states that it is opensource.

1. download
ftp://ftp.foolabs.com/pub/xpdf/xpdf-3.02pl5-win32.zip

2. unzip the contents.

3. open a command prompt window and navigate to the unzipped directory.

4. Issue the following command:
PDFTEXT -?

5. read the displayed text

6. play with the different command line switches using your PDF files until you are satisfied with the result.

7. Use the ShellExecute() function in your application.

=========
You will probably need to wait/sleep for a moment for the shelled process to finish.
