Testing Debenu Quick PDF Library

[Klaas den Dekker]

Hi,
I'm testing the Debenu Quick PDF Library with Fivewin + xHarbour but I'm having problems starting up.
I use:
cLicense := "jx4aq86h5ou5mk9i86644936y"
xId := DllCall( hDLL,nil,"DPLCreateLibrary" )
xVal := DllCall( hDLL,nil,"DPLUnlockKey",xId,StrPtr(cLicense) )
DllCall( hDLL,nil,"DPLReleaseLibrary",xId )

XId return a value (f.i. 83652944) but xVal allways return 0, what means that the library is not correct unlocked.
The problem according to the helpdesk of Debenu is that the string cLicense is not correcty parsed to the function.
I also tried:
xVal := DllCall( hDLL,nil,"DPLUnlockKey",xId,cLicense )

Can anyone help me?
Does anyone use the Debenu Quick PDF Library?

best regards,
Klaas den Dekker

Klaas,

What FWH version are you using ?

Are you using Harbour or xHarbour ? Borland ?

thanks

[Klaas den Dekker]

xHarbour 1.2.1 rev. 9421
Borland 5.82

[Antonio Linares]

Klaas,

What FWH version are you using ?

[Klaas den Dekker]

FWHX 12.07

[Antonio Linares]

Klaas,

How are you initially setting the value of hDLL ?

[Klaas den Dekker]

Yes, I am:

STATIC hDLL

IF DebLoadDLL()
cLicense := "jx4aq86h5ou5mk9i86644936y"
xId := DllCall( hDLL,nil,"DPLCreateLibrary" )
xRet := DllCall( hDLL,nil,"DPLUnlockKey",StrPtr(cLicense) )
DllCall( hDLL,nil,"DPLReleaseLibrary",xId )
ENDIF
....


** Load Debenu lib
FUNCTION DebLoadDLL()
LOCAL lResult := .T.
hDLL := LOADLIBRARY( GsExeDir()+"\"+DLLfile )
IF ABS( hDLL ) <= 32
lResult := .F.
ENDIF
RETURN lResult

[Antonio Linares]

Klaas,

Could you please email me the DLL in a ZIP file renamed as ZOP ? thanks

no he podido registrar la clave de la licencia, aun la DEMO antonio, nUnlock siempre vale 0, probado con xharbour, modo consola.

Carlos,

Code: Select all  Expand view  RUN

nUnlock := DllCall( hDLL, DC_CALL_STD, "DPLUnlockKey", nInstanceID, AnsiToWide(cLicense1) )

Excellent!

We did not considered this possibility, that a wide string was expected. Very good!

[Klaas den Dekker]

Hi Antonio and Carlos,

Indeed, DPLUnlockKeyA works, thanks very much!

nUnlock := DllCall( hDLL, DC_CALL_STD, "DPLUnlockKeyA", nInstanceID, cLicenseUSD ) -> this works
nUnlock := DllCall( hDLL, DC_CALL_STD, "DPLUnlockKey", nInstanceID, AnsiToWide(cLicenseUSD) ) -> this does not work

Now I can continue with the conversion of EMF to PDF with this lib.

Best regards,
Klaas den Dekker

[nageswaragunupudi]

Now I can continue with the conversion of EMF to PDF with this lib.

Does the library provide for direct conversion of EMF to PDF ?

[Antonio Linares]

Klaas,

nUnlock := DllCall( hDLL, DC_CALL_STD, "DPLUnlockKeyA", nInstanceID, cLicenseUSD ) -> this works

That seems the right one as usually "A" stands for Ansi and "W" for wide. Thats the way Microsoft uses to name the Windows API functions.

A very good finding from Carlos, as we did not considered that possibility
