  1. POUpdating a document in Google Docs using the API?
    text
    copied!<p>I want to update the contents of the already uploaded Google Doc file. I'm using the below code:</p> <pre><code>DocumentsService service = new DocumentsService("app-v1"); string auth = gLogin2(); service.SetAuthenticationToken(auth); Stream stream = new MemoryStream(ASCIIEncoding.Default.GetBytes( "CONTENTS PLEASE CHANGE")); DocumentEntry entry = service.Update(new Uri("feedURL"), stream, "text/plain", "nameOfDoc") as DocumentEntry; </code></pre> <p>For "feedURL" I tried using all the possible links: alternate, self, edit, edit-media even resumable-edit-media, but I keep on getting exceptions.</p> <p>Also how do I read a response with such requests?</p> <p>I just started using this API. Earlier, I was using it on the protocol level so was sending GET/POST requests and receiving web responses. I don't know how to get or read response in this case.</p> <p>UPDATE:</p> <p>Now the code I'm using is:</p> <pre><code>RequestSettings _settings; string DocumentContentType = "text/html"; _settings = new RequestSettings("Stickies", "EMAIL", "PASSWORD"); var request = new DocumentsRequest(_settings); //var entryToUpdate = doc.DocumentEntry; var updatedContent = "new content..."; ; var mediaUri = new Uri(string.Format(DocumentsListQuery.mediaUriTemplate, rid)); Trace.WriteLine(mediaUri); var textStream = new MemoryStream(Encoding.UTF8.GetBytes(updatedContent)); var reqFactory = (GDataRequestFactory)request.Service.RequestFactory; reqFactory.CustomHeaders.Add(string.Format("{0}: {1}", GDataRequestFactory.IfMatch, et)); var oldEtag = et; DocumentEntry entry = request.Service.Update(mediaUri, textStream, DocumentContentType, title) as DocumentEntry; Debug.WriteLine(string.Format("ETag changed while saving {0}: {1} -&gt; {2}", title, oldEtag,et)); Trace.WriteLine("reached"); </code></pre> <p>And the exception I'm getting is: {"The remote server returned an error: (412) Precondition Failed."} I'm getting this exception at <code>DocumentEntry entry = request.Service.Update(mediaUri, textStream, DocumentContentType, title) as DocumentEntry;</code></p>
