Open Document from binary string without local download

[milonass]

Is it possible to open a document by transferring directly the binary string, e.g. using doVerb( ' ','OpenDocument',data,...)?

Thanks.

Hello Thomas,

You need to specify the "UseStreamsDirectly" flag:

Code: Select all

SetProperty("Documents.UseStreamsDirectly", 0, 0)

Thank you. How do I supply the variant Parameter? Is it a BSTR?

Thank you.

Hi Thomas.

No, the document source can be:

1. path to file on the disk
2. URL to remote file
3. IStream-based object (good alternative for your case, look to our SDK examples to see how to pass stream)

Also, as mentioned above - you may set the special property that forces viewer activeX to keep strong relation between input-stream and opened document. This relation is required for regular end-user's 'Save Doc to Source' feature. Otherwise, when user clicked 'Save' button for document that was loaded from stream - it will show the 'Save As..' dialog instead of simple and silent saving to the source-stream.

In C++:

Code: Select all

ATL::CComBSTR propName("Documents.UseStreamsDirectly");
ATL::CComVariant propVal(true); // == ATL::CComVariant propVal(1); == ATL::CComVariant propVal("true");
pdfViewer.SetProperty(propName, propVal, 0);

In C#:

Code: Select all

pdfViewer.SetProperty("Documents.UseStreamsDirectly", true, 0);
// == pdfViewer.SetProperty("Documents.UseStreamsDirectly", 1, 0);
// == pdfViewer.SetProperty("Documents.UseStreamsDirectly", "true", 0);
