CloseDocument not closing subsequent documents (MDI)

[GregWente]

The CloseDocument(ID) will not release the opened documents and I must CloseAllDocuments before they will release.

Hi, GregWente.

It may occur because CloseDocument() is asynchronous - it closes the document view, release all internal objects but may keep captured the source file for some short time (file may be captured by background rendering thread that cannot be stopped without any waiting). If you want the guaranteed release of source file (it may wait for stop some background processes) - use it:

Code: Select all

pdfViewer.SetDocumentProperty(docID, "SyncClose", 1, 0);
pdfViewer.CloseDocument(docID);

HTH.
