This is not a question about the Quick PDF library...
Say that we have for instance the QuickPDF Reference Guide and we want to open it directly within the GetInformation function.
IOW :
Would there be a way to start Acrobat directly on a bookmark topic ?
Using the WINDOWS START command, the only thing I can do , so far, is to open the PDF :
START "iSEDQuickPDF 5.11 Reference Guide.pdf"
Would there be arguments to make it search for a string or a bookmark topic ?

If You are using Acrobat 7 there is a paper which list all opening parameters that can be set.

Unfortunatelly I cant use Acrobat 7 because I'm on a Win98 machine.
As far as I know, there is no way to run it on this OS.
On the other hand, I cant go to W2K because I have a mainframe terminal emulator that wont run on it...
So, I have to solve it on version 7...

Look at Adobe's IACReference.PDF. You can use the DDE method DocGoToNameDest to go to a named destination, or DocGoTo to go to a specified page. Both work with Reader as far back as version 4, and up to the latest version. Note that not all of the methods will work with Reader.

Maybe one could help me out with a VBScript to do it ?
I mean, a VBScript to open a PDF file and then issue a DocGoToNameDest("COMPUTE") for instance...

DDE isn't supported by VBScript. Here's a simple examle in "C". Note that it hasn't been fully tested. A .zip with source and .exe is here:
http://www.geocities.com/sea_sbs/files/pdfc.zip
usage examples:
pdfc -p 33 e:\temp\mypdf.pdf (go to page 33 of doc)
pdfc -d "compute" e:\temp\mypdf.pdf (go to named dest)

Hi Chicks
Thank you so much 4 your support !
As a matter of fact, it's not working, unfortunatelly.
Here's the PDF I'm trying to open :
http://www.DES.online.unimep.br/au/cobol8591.pdf
This is the command line I'm using :
pdfc.exe -d "COMPUTE" C:\WORK\COBOL8591.PDF
What happens ?
Get these screens :

Thanks again !

Jose,
1. The "missing index" warning happens when you open the document manually with Reader, too. Nothing to do with pdfc.exe.
2. Are there any Named Destinations in this document? Going to a Named Dest is not the same thing as searching...

Jose,
Here's a VERY BASIC example of a wrapper vbscript for pdfc.exe for PDF files that don't have named destinations. It uses QuickPDF to search through the outline (top level only - you'll need to enhance to search through child levels) for a specified term ("Index", in this case). If it finds the term, it gets the page number from the outline, then execs pdfc.exe with the page number and document path.
You'll need to do some serious enhancements to make it useful.
------------------------------------------------------
Dim QP, objShell
Dim inFileName
Dim id, page, title, term
Dim ret
'-- Init iSedQuickPDF and FSO objects
Set QP = CreateObject("iSED.QuickPDF")
Set objShell = CreateObject("Shell.Application")
'-- Set file name
inFileName = "C:\temp\cobol8591.pdf"
'-- Unlock the PDF library
Call QP.UnlockKey(" -- MY QUICKPDF KEY -- ")
'-- Load the input PDF
ret=QP.LoadFromFile(inFileName)
WScript.Echo ret
'-- Search for the Index
term="Index"
'-- Loop through Outline
id = QP.GetFirstOutline()
Do While id > 0
title = QP.OutlineTitle(id)
If title=term Then
page = QP.GetOutlinePage(id)
WScript.Echo "Found '" & term & "' on page:" & page
objShell.ShellExecute "pdfc.exe","-p " & page & " " & inFileName, "", "open", 1
Exit Do
End If
id = QP.GetNextOutline(id)
Loop
'-- Clean up
Set QP = Nothing
Set objShell = Nothing
'-- We're Done!
WScript.Quit(Err)

Jose,
This little guy should do what you want:
http://www.geocities.com/sea_sbs/files/pdfsrch.zip
Searches recursively through all bookmarks and children to match a search term from commandline:
pdfsrch "c:\my pdfs\IACReference.pdf" "link annotation"
Will do case-insensitive search and match "Link Annotation" bookmark, then open to its reference page (31) in IACReference.pdf in Reader.
Requires the DLL version of QuickPDF in your path.

You offer a finger and I want the whole arm...
The thing is : sometimes a WHOLE WORD search is needed... In my case, I searched for COMPUTE, from the COMPUTE verb. However, it found OBJECT-COMPUTER before... This wasnt the topic I wanna open upon...
BTW, only today I read your posting about that Girl From Ipanema. I'm far away (500km) from her ! I'm on the interior side of the Country and she's in Rio, which is on the coast, of course.
Where are U talking from ?

OK, download it again. I changed from a simple "instr" match to a regex match, so you will have the power of regular expression pattern matching to specify exactly how to search.
For the rules of this particular regex engine, search for "REGEXPR" here:
http://www.powerbasic.com/support/help/pbcc/index.htm
Try these two example searches to see the difference:
pdfsrch cobol8591.pdf compute
pdfsrch cobol8951.pdf "\bcompute\b"
The pattern can get a lot more complex than this simple example. Make sure to enclose the regex pattern in quotes, or the CMD shell may try to interpret them.
