Mr Popup,

You will need do some research and see how strings and arrays work in Jade.  The code examples show how the C# wrapper loads and saves strings using the DLL calls.

Andrew.

Thank you Andrew.

MrPopup,

Here is the C# wrapper code for LoadFromString and SaveToString ?  It should be helpful with porting it to Jade.  The C# wrapper is calling the DLL also.

Andrew.

        public int LoadFromString(byte[] Source, string Password)
        {
            if (dll == null) return 0;
            else
            {
                GCHandle gch = GCHandle.Alloc(Source, GCHandleType.Pinned);
                IntPtr bufferID = dll.DebenuPDFLibraryCreateBuffer(instanceID, Source.Length);
                dll.DebenuPDFLibraryAddToBuffer(instanceID, bufferID, gch.AddrOfPinnedObject(), Source.Length);
                int result = dll.DebenuPDFLibraryLoadFromString(instanceID, bufferID, Password);
                dll.DebenuPDFLibraryReleaseBuffer(instanceID, bufferID);
                gch.Free();
                return result;
            }
        }

        public byte[] SaveToString()
        {
            if (dll == null) return new byte[0];
            else
            {
                IntPtr data = dll.DebenuPDFLibrarySaveToString(instanceID);
                int size = dll.DebenuPDFLibraryAnsiStringResultLength(instanceID);
                byte[] result = new byte[size];
                Marshal.Copy(data, result, 0, size);
                return result;
            }
        }

I note that the DPLLoadFromStringA construct makes use of both char (ansi) and w_char (unicode) data types.  
No other constructs that I have used mix the two types.
Thanks.

I think the problem is before the LoadFromString.
You should check each returning value.
What about the returning value of DeletePages?
It should be the number of the remaining pages.
I don't know Jade... the string content should be Ansi...

is it okay with another dll-version?
If not: Please upload the pdf anywhere
and post the link - so we can check it.
 
Cheers, Ingo

Good morning,

Using DLL version 10.  Have tried both DPLLoadFromString and DPLLOadFromStringA. Same problem.  Jade development environment is being used.  This is the obny call I have had an issue with.

The code is:

vars
qp : PDF;
st : String;
begin
create qp transient; //create and unlock library
qp.loadFromFile("c:\temp\seka.pdf",""); //import existing pdf (4pages)
qp.deletePages(2,qp.pageCount-1); //delete all pages except page 1
qp.selectPage(1); //select page 1
st := qp.saveToString; //get pdf as a string and hold
write st.length; //check length of string
write st; //display string
delete qp; //delete and release library
create qp transient; //create and unlock library
qp.loadFromString(st,""); //load pdf from held string
write qp.lastErrorCode; //display error code
qp.saveToFile("c:\temp\test_save.pdf"); //save new document as a pdf
delete qp; //delete and release library
end;

All calls are successful except the loadFromString call.

Thank you.
