Hi Bart!

Where's the problem?
I've extracted your form completely and it's all okay.
I've removed the adress ...
I've done it with version 7.26:

There was a truncating bug in 8.11 that has been fixed in 8.12. The text is extracting correctly in 8.12 using GetPageText 0, 3 and 7. 8.12 is a free upgrade for owners of 8.11. The bug was caused by the recent major Unicode changes to the 8.11 version from 7.26.

Interestingly your PDF is 705mm wide by 998mm high which seems a big big for invoice. This currently affects the output of 8.12 with option 7.

Andrew.

Hello Andrew

I'm testing the new version and i got the text truncated with the 8.12 equals 8.11

The Size that return dll.QuickPDFStringResultLength(instanceID) is half that real text
In the 8.12 version is necesary to change two lines in the RC method for the Visual Basic Class

Private Function SR(ByVal data As IntPtr) As String
1-->>>   Dim size As Integer = dll.QuickPDFStringResultLength(instanceID) <<<--
            Dim result As Byte() = New Byte(size - 1) {}
            Marshal.Copy(data, result, 0, size)
2-->>>   Return Encoding.Default.GetString(result) <<<--
        End Function

1 ->> Dim size As Integer = dll.QuickPDFStringResultLength(instanceID) * 2
2 ->> Return Encoding.Unicode.GetString(result)

Best Regards

Thanks for the fixes. I will test it and then get these changes into the VB code. I was doing all my testing with C# and it is working correctly.

The C# code for your reference is

private string SR(IntPtr data)

{

int size = dll.QuickPDFStringResultLength(instanceID);

byte[] result = new byte[size * 2];

Marshal.Copy(data, result, 0, size * 2);

return Encoding.Unicode.GetString(result);

}

so in VB it probably should be

Private Function SR(ByVal data as IntPtr) As String

Dim size As Integer = dll.QuickPDFStringResultLength(instanceID)

Dim result As Byte() = New Byte(size * 2 - 1) {} // as per post below

Marshal.Copy(data, result, 0, size * 2)

Return Encoding.Unicode.GetString(result)

End Function

Andrew.

Hello,
Change the code line Dim result As Byte() = New Byte(size * 2) {} to Dim result As Byte() = New Byte(size * 2 - 1) {}
