Hello,
I'm trying to implement asynchronous call to COM interface below and having trouble understanding what C# code will allow me to update progress bar while call is running.
I have an object called MyDownloader which has a method of BeginDownload below, I need to periodically update main program about progress and when call is completed to return back to processing.
Any sample code?
HRESULT BeginDownload(
IUnknown* onProgressChanged,
IUnknown* onCompleted,
VARIANT state,
IDownloadJob** retval
);
Parameters
onProgressChanged
[in] An IDownloadProgressChangedCallback interface that is called periodically for download progress changes before completion.
onCompleted
[in] An IDownloadCompletedCallback interface (C++/COM) that is called when an asynchronous download operation is complete.
state
[in] The caller-specific state that AsyncState Property of IDownloadJob returns.
retval
[out] An IDownloadJob interface that contains the properties and methods that are available to a download operation that has started.
