I have an Access 2007 project, I want to get some data from a Form Pdf file.

When the function "DPLGetFormFieldCaption" or "DPLGetFormFieldValue" run, the Access application will shutdown with no any error message.

P.s. The function "DPLFormFieldCount" can return the count of fields correctly.

Code list:

Dim iInstanceID As Long
Dim iFieldsCount As Long
Dim iOpenStatus As Long
Dim strCaption As String
Dim iIndex As Long
Dim iErrorCode As Integer

iInstanceID = DPLCreateLibrary()

If DPLUnlockKey(iInstanceID, QP_LicenseKey) = 1 Then

    iOpenStatus = DPLLoadFromFile(iInstanceID, strFileName, "")



    iFieldsCount = DPLFormFieldCount(iInstanceID)

    iIndex = iFieldsCount

    strCaption = DPLGetFormFieldValue(iInstanceID, iIndex)
    DPLReleaseLibrary (iInstanceID)

Else

MsgBox "Error"

End If

Hi!

I don't have a real solution but to give you an idea...

I've made same experiences with ms access 2007 (older ms access versions work fine!).

It should have to do about how to handle the string values.

The QuickPDF-function returns with a widestring...

Cheers and welcome here,

Ingo

Hello,

Out of interest can you try calling

"DPLGetFormFieldCaptionA" or "DPLGetFormFieldValueA" and see if is still crashes.

This time, I try to use C++ code to do this , but I cant get the value that I need. Only a blank string be returned when the "DPLGetFormFieldCaption" work. The function "DPLFormFieldCount" can work correctly and return a int.

       int iInstanceID;
        int iOpenStatus;
        int iFieldsCount;
        wchar_t* strCaption;

iInstanceID = DPLCreateLibrary();

if (DPLUnlockKey(iInstanceID, L"XXXXXXXXXXXXXX") == 1)

{

               iOpenStatus = DPLLoadFromFile(iInstanceID, L"E:\\a.pdf", L"");
                iFieldsCount = DPLFormFieldCount(iInstanceID);
                 strCaption = DPLGetFormFieldCaption(iInstanceID,4);

ShowMessage(strCaption);
ShowMessage(IntToStr(iFieldsCount));
}
DPLReleaseLibrary(iInstanceID);

Thanks!

Laiskam,

Can you please send us the A.PDF so we can test it in C# / Delphi to make sure it is possible to process this file correctly.

Or you can try adding the code into a custom script in the Debenu Quick PDF library Demo program.

Andrew.

Thanks Andrew,

This issue had solved with C++. I make a stupid mistake. I should use the function "GetFormFieldTitle" , not "GetFormfieldCaption", because the caption of field is blank.

But it cant work correctly with VBA.
