I have this code for combining two documents, but when I get to the last statement, it throws the error on the DoDocumentVerb line.. I'm not sure what I'm missing, or if there's a better way to do what I'm trying to accomplish.


_viewer.SetProperty(@"Operations.InsertPages.RangeType", @"Exact");
_viewer.SetProperty(@"Operations.InsertPages.FromExternal", 0);
_viewer.SetProperty(@"Operations.InsertPages.DocID", sourceId);
_viewer.SetProperty(@"Operations.InsertPages.InsertBefore", 0);

_viewer.DoDocumentVerb(targetId, null, @"InsertPages", null, out _, (int) PXCVA_Flags.PXCVA_NoUI);


System.Exception

Message=0. See inner exception for details.

Never mind, I figured out I had modified some parameters from the example, but not all the ones I needed. I got it to work without error now.

This was the code I ended up with:
_viewer.SetProperty(@"Operations.InsertPages.FromExternal", 0);
_viewer.SetProperty(@"Operations.InsertPages.DocID", sourceId);
_viewer.SetProperty(@"Operations.InsertPages.InsertBefore", 0);

_viewer.DoDocumentVerb(targetId, null, @"InsertPages", null, out _, (int) PXCVA_Flags.PXCVA_NoUI);

So I wanted to close the source document when this was done, but when I do that the original document disappears.

var sourceId = 4096;
var targetId = 4095;

_viewer.SetProperty(@"Operations.InsertPages.FromExternal", 0);
_viewer.SetProperty(@"Operations.InsertPages.DocID", sourceId);
_viewer.SetProperty(@"Operations.InsertPages.InsertBefore", 0);

_viewer.DoDocumentVerb(targetId, null, @"InsertPages", null, out _, (int) PXCVA_Flags.PXCVA_NoUI);

// this is the line that always seems to close the first tab regardless of the documentId
_viewer.DoDocumentVerb(sourceId, null, @"CloseDocument", null, out _, (int) PXCVA_Flags.PXCVA_NoUI);

In the end, I"m left with 4096 regardless of whether I close sourceId or targetId.

Is there an additional step I need to take to allow the combine to complete before I close the original document?
