Am trying to use the AcroForms plug-in using IAC in VC++ to populate fields by opening PDFs in memory. The method PDDoc->OpenAVDoc is bringing the Acrobat window in front. If I comment this method, am getting the error "No form is Open in Acrobat Viewer". Below is my code

// Create the Acro App object
pAcroApp = new CAcroApp;
pAcroApp->CreateDispatch("AcroExch.App", &OleExc)

// Create the PDDoc object
pAcroPDDoc = new CAcroPDDoc;
pAcroPDDoc->CreateDispatch("AcroExch.PDDoc", &OleExc)

// Open the PDF File
pAcroPDDoc->Open(cstrPdfFile)

// Create the AVDoc object
pAcroAVDoc = new CAcroAVDoc;
pAcroAVDoc->AttachDispatch(pAcroPDDoc->OpenAVDoc(cstrPdfFile), true);

// Create the Forms Automation object
pFormApp = new IAFormApp;
pFormApp->CreateDispatch("AFormAut.App", &OleExc)

// Get the collection of fields pFields = new IFields(pFormApp->GetFields());

The above line is producing the error mentioned above on commenting the OpenAVDoc method. Can someone provide help??

The error also comes if I make a call to AcroApp.Hide method before calling the OpenAVDoc method.

You are getting this error message because your pFormApp object can't find a form to get the fields from. You have to open the form in the Viewer (via OpenAVDoc) first. The same is true for AcroApp.Hide. If you don't have a doc open, it has nothing to hide.

Nix,

Am making the call to OpenAVDoc before creating the pFormApp object.

Also, am unable to find out any documentation specifying the reason for this error and when it'll occur. There is only a single line mentioned about this error in the IACReference.pdf
