Invalid argument error for AddAttachment

[miromr]

Hi,
what is wrong?
in this code?
Thank Miro

int docId;
PDFX2.OpenDocument(@"C:\AAA\aaa.pdf", "", out docId, 0);
Object dOut=null;
object[] dIn = new object[3];
dIn[0] = @"C:\AAA\bbb.pdf";
dIn[1] = "Attachment";
dIn[2] = "Description" ;
try
{
PDFX2.DoVerb("Document[0]", "AddAttachment", dIn, out dOut, 0); <--------- "Invalid argument" error
}
catch (Exception ex)
{

ShowErrorMessage(System.Runtime.InteropServices.Marshal.GetHRForException(ex));
}
PDFX2.CloseAllDocuments();

Hello miromr,

I believe that the docID you are trying to pass to the DoVerb method is your problem. Please try replacing that with the docID variable from earlier in your code

Best,
Stefan

Hi Stefan
problem still persists:

private void button1_Click(object sender, EventArgs e)
{
PDFX2.OpenDocument(@"C:\AAA\aaa.pdf", "", out hndDoc, 0);
Object dataOut = null;

Object[] dataIn = new object[3];
dataIn[0] = @"C:\AAA\bbb.pdf";
dataIn[1] = "Attachment";
dataIn[2] = "Description";
try
{
PDFX2.DoVerb("Document[0]", "AddAttachment", dataIn, out dataOut, (int)PXCVA_Flags.PXCVA_NoUI);
}
catch (Exception ex)
{
ShowErrorMessage(System.Runtime.InteropServices.Marshal.GetHRForException(ex));
}
PDFX2.CloseAllDocuments();
}

Thank Miro

Hello Miro,

Why don't you try the
DoDocumentVerb(docId, NULL, "AddAttachment", DataIn ...
method?

Best,
Stefan
