You can use the Adobe Reader plug-in to display a PDF in your application! I wrote a simple wrapper with EuCOM and uploaded it to The Archive.

I need to add a pdf viewer to my program, but can't get this to run.

I have downloaded eucom but cant get it to run. seems to conflict with win32lib or something. Anyone have this working? or have any other suggestions.

Yes I do have adobe acrobat reader installed on my system.

The problem so far is with EUCOM and namespace issues.

If I run the demo from EUCOM - I get the following error

D:\EUPHORIA\Include\w32memory.ew:541 
A namespace qualifier is needed to resolve w32removeIndex. 
w32removeIndex is defined as a global symbol in: 
    D:\EUPHORIA\win32\Include\w32utils.e 
    D:\EUPHORIA\Include\w32utils.e 
 
            vSets[i] = w32removeIndex(lAddrSub, vSets[i]) 
                                    ^

Sometimes i'm so dumb.

Ok now if I try to run acroview I get the following error

D:\EUPHORIA\win32\Include\Win32Lib.ew:24306 in function MessageProcessor()  
A machine-level exception occurred during execution of this statement

    lParam = 27656816 
    id = 3 
    lHandledEvent = 15 
    lTemp = 1 
    result = 0 
    lUserReturn = <no value>

Looking into this a little further, pSource = -2761 is kMainMsg, so that's perfectly legit. iMsg = 5 which is WM_SIZE, so this is probably occuring during the initial w32HResize event after the w32HOpen event.

In my Win32Lib, line 24306 is just "else" so I'm not what's causing the machine error there. Which is why I'm curious if you've got a different version of Win32Lib.

24304            if length(result) > 1 then
24305                result = result[2] 
24306            else 
24307                result = 0 
24308            end if 

AcroView seems to run fine for me. I'm using Win32Lib 0.70.4a 17-June-2008. I've got Adobe Acrobat 8 Standard, but I've also tested this on a computer with Adobe Reader 8. I will try to test with Adobe Reader 9, which I believe is the latest version.

I have not been able to reproduce a crash when launching AcroView, even with Adobe Reader 9 installed. One thing I did notice while investigating this, is that the AcroPDF COM object seems to be a tad... buggy. Sometimes getOpenFileName() causes a machine-level error, which I've never seen with any other program. Maybe EuCOM is leaking memory somewhere, at least I assume that could be the cause the problems.
