IIS Windows Server 2012 R2 problem with library

Hi Boris,

Here are the results so far and I need help...

There are some function names (and maybe parameter changes) from version 5.11 to 7.21/7.18 and up to 10. I hope I can find out which function and how. But this is not a problem at the moment. I cannot come to the point to do anything after entering unlock key, because the DLL freezes when entering the unlock key when working on Windows Server 2012.

The main problem is that all versions DOESN'T work on IIS  Windows Server 2012 when used in WEB application

All  versions works on DEKSTOP application also on Windows Server 2012

On 2013 we bought version 7.21 and 7.18 on 2010 in hope we will be able to use our WEB application we use since 2003 to work with PDF on Windows Server 2012. Doesn't work.

I am addressing the authors of this good library - please test the library on some WEB application on Windows Server 2012 and you will realize, you cannot even enter the unlock key, therefore not being able to use the DLL at all.
We are using your library since 2007. and now we are stuck. We did all kind of tests and the problem is your DLL under IIS on Windows server 2012 in WEB application. It is not fair we cannot get any support here.


1. In version 5.11 works on XP, Windows 7, Windows server 2003, Windows Server 2008:
hDLL := LoadLibrary("iSEDQuickPDF.dll")   
then:
cFarProc := GetProcAddress(hDLL, "iSEDUnlockKey",.T.,LONG,         STRING)
cString := "the retail unlocking key we bought"
r := CallDLL( cFarProc,cString)
IF r == 0
    FreeLib32( hDLL )
    MsgInfo("Cannot verify the PassKey !" )
    QUIT
ENDIF
(this  doesn't work on Windows Server 2012)
   


2. Using Version DEMO 10
This code  works on XP, Windows 7, Windows server 2003, Windows Server 2008 
I had to use different named function for unlocking:
hDLL := LoadLibrary("DebenuPDFLibraryDLL1015.dll")   
then:
cFarProc := GetProcAddress(hDLL, "QuickPDFUnlockKey",.T.,LONG,         STRING)
cString := "the retail unlocking key we bought"
r := CallDLL( cFarProc,cString)
IF r == 0
    FreeLib32( hDLL )
    MsgInfo("Cannot verify the PassKey !" )
    QUIT
ENDIF
(this  doesn't work on Windows Server 2012)

No one is using this DLL in web app under IIS Windows Server 2012 ?

Thanks Ingo,

The link you pointed to is educative, but it doesn't solve my problem.
I need the "allow 32-bit" to be enabled, because my app is 32-bit.
Also, removing the filter for 32-bit will not work, I need it because of the nature of my app.

Please, try to check if somebody tested my app I sent to run on Windows Server 2012 (64-bit evemn I don't know if there is Windows Server 32-bit at all)
The application does only 2 things:
1. Loads the DLL
2. Enters the unlock key and issues the message on screen: "Unlock key entered"
3. Quits

If the point 1. fails, it issues the appropriate message and quits

On any Windows Server so far I ever installed this test program, it shows the message that "Unlock key entered"
Only on Windows Server 2012 it just hangs after the DLL is loaded. The DLL loading is not a problem, because the loading is done by practically Windows API and I get a handler (some quite a big integer)

Your experience running this test app would show us which direction to take in solving this issue.
You can also run  this test app on any other machine with IIS installed (other than Windows Server 2012 of course) and you will see that it runs properly
If you don't test the app I sent, you cannot try to explain or help.

Please try to help me.

Thanks
Boris
