function int QuickPDFCreateLibrary() library “QuickPDFDLL0712.dll”
function int QuickPDFReleaseLibrary(int iInstanceID) library “QuickPDFDLL0712.dll”
function int QuickPDFUnlocked(int iInstanceID) library “QuickPDFDLL0712.dll”
function int QuickPDFUnlockKey(int iInstanceID, String sRegKey) library “QuickPDFDLL0712.dll”

Now if I code a function like this it always returns FALSE.
integer li_instance_id
string ls_key

li_instance_id = QuickPDFCreateLibrary()
ls_key = “j74gf38u9i88w97zu88w7gb7y”

if li_instance_id > 0 then
if QuickPDFUnlocked (li_instance_id) = 0 Then
/* Unlock DLL support */
if QuickPDFUnlockKey (li_instance_id, ls_key) = 0 then
fs_err_msg = “Error: Could not unlock iSED PDF DLL.”
QuickPDFReleaseLibrary (li_instance_id)
Return (FALSE)
end if
end if

QuickPDFReleaseLibrary (li_instance_id)

Return (TRUE)

Based on all available help, the above function should work. I even changed the key argument to pass by reference and it failed. Also change the case to uppercase for the key string, still failed. Now I have used passed iSed DLLs with no problems. But this one?

Any help would be welcome

In the beta package, you need to use the new import headers. I created a simple dialog-based MFC project, then:

1. Added the import headers to the project,
2. The DLL files to the release folder,
3. A single button and OnClick() function.

void CQuickPDFDLLTestDlg::OnBnClickedButton1()
{
QuickPDFDLL0712 QPL(“QuickPDFDLL0712.dll”);
if(QPL.UnlockKey(“j74gf38u9i88w97zu88w7gb7y”)==1)
{
QPL.DrawTextW(100, 500, “Hello world”);
QPL.SaveToFile(“C:\\temp\\HelloFromDLL.pdf”);
}
}

The result of this was a single PDF created in the temp folder. Please let us know if you have any problems with this or open a support case here – http://www.quickpdflibrary.com/support/support-query.php

Cheers…

Any help would be appreciated

p.s.
Yes I saw the information about the function changes and how to instantiate the library. And bookmarks in the reference pdf is greatly needed.

The DCU files for Delphi 2009 are still experimental and so were not included with the latest release. The DCU files for Delphi 2006 should work with Delphi 2007.

We have the DCU files for Delphi 2009, however, they are still experimental since there were substantial changes between Delphi 2008 and 2009.

We’re aiming to include these with the next release.
