New Post: IsLogin Function Required

I want to inform you that there is not a single function to check whether the login was successful or not or how longer particular user may log-on.

Patch Declined: #5520

ghollosy — Fri, 12 Mar 2010 16:20:08 GMT

ghollosy has declined patch #5520.

Comment:
The implemented new property DownloadUrl does the same thing. Of course, this property is and can be only populated when the details web page of the given file/folder is "visited"/downloaded (e.g. by using GetWebFile or GetWebFolder or GetWebFolderItem methods) .... as you did within the patch:
...
Uri uriWebFolderItemView = GetWebFolderItemViewUri(Session, webFolderItem);
WebFileInfo plik = (webFolderItem as WebFileInfo);
string responseString = webClient.DownloadString(uriWebFolderItemView);
plik.Permalink = ParseWebFileInfoPermalink(responseString);
...

BUT I would never put this extra web communication into the ListXX method. This method's goal is to collect the list of sub files and folders as FAST as possible and as MUCH ADDITIONAL information as possible. If you need more data like permalink, than do a custom loop in your own code, but do not punish other users/applications who/which are not interested in this extra information at all!

This little code snippet does the same thing as yours:
var webFiles = ListSubWebFolderFiles(...);
foreach (var webFile in webFiles)
GetWebFile(webFile); //or webFile = GetWebFile(webFile);

There is only one little difference between the content/behaviour of your Permalink and the my DownloadUrl, naming, that using DownloadUrl in a Web Browser would always pop up the download dialog of the browser, while Permalink would only pop up it if browser cannot display its content, otherwise it opens the file within the browser.
If you need this Permalink behaviour, you only need to remove '/download' suffix from DownloadUrl.

Patch Uploaded: #5520

Downloaded the latest version and was playing with the console sample app, but it appears to fail at login.

HgCo.WindowsLive.SkyDrive.LogOnFailedException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object.
at HgCo.WindowsLive.SkyDrive.SkyDriveWebClient.LogOn(String userName, String userPassword) in SkyDriveWebClient.cs:line 254

Which looks like its failing on
responseDocument.GetElementbyId("fmHF")

The text in the responsedocument looks like its not getting a valid page..

New Post: Upload or Rename file should return a new WebFileInfo item.

ghollosy — Thu, 25 Feb 2010 10:12:59 GMT

Basically, you're right. Those functions should return an instance of the new/modified object. However, the methods were designed to match to the capabilities of SkyDrive "API" (= the Web pages of SkyDrive site) provided by Microsoft. Therefore if you check how can you upload a file via a browser, you would find that after upload (even if you upload only a sinlge file), the browser is redirected to the folder list view. It means the "official" way to get the information of the new file is to list the folder.

Of course, a tricky workaround exists to avoid this extra download. You could create a dummy WebFileInfo object based on the information available from the uploaded file and its webfolder, and you can call GetWebFileInfo with that dummy instance. The next release would contain these dummy object creation features as static methods in WebFileInfo and WebFolderInfo classes.

I would not recommend to put this workaround into UploadWebFile or RenameWebFile method as it costs extra HTTP communication and there can be usages where it is fully enough to list the folder's content only when all upload is finished (which could be much faster than refreshing each file one by one). If someone needs immediate instance refresh, then he/she can use the workaround mentioned above.

New Post: Upload or Rename file should return a new WebFileInfo item.

wyvern — Tue, 23 Feb 2010 06:56:29 GMT

When use Upload or Rename method, there should be a new item to return from function. such as: void UploadWebFile(string fileName, WebFolderInfo webFolderParent) -> public WebFileInfo UploadWebFile(string fileName, WebFolderInfo webFolderParent), RenameWeb* should also like this pattern. Because if NO new item returned, we must ReList current or specified folder to add/update new item, it waste time&bandwidth. If return new Web[File|Folder]Info item we can directly update UI control view instead of Update(ReListSubFolder) status. Think this scenario, one folder in skydrive contains 10K files, rename one file, then re list 10K files in this folder to update status. So bad!

Project Description

SkyDrive .Net API Client allows developers to easily integrate Microsoft's Windows Live SkyDrive online storage and sharing services into their own applications. It's developed in C# using .Net 2.0.

What is this?

This project is an open source client for Windows Live SkyDrive written for the Microsoft .NET Framework. This is NOT an offical, Microsoft API (and to be honest, it's not a true API)! However, this library will greatly facilitate the development of 3rd party applications for developers already familiar with the Microsoft .NET technology stack.

How does it work?

At the time of this writing, as far as I know, there is no official API to use for SkyDrive. SkyDrive Client uses the same communication protocols as a web browser: it's requesting HTML pages, parsing them (thanks Html Agility Pack project) and posting back HTML forms filled appropriately. Consequently, SkyDrive WebClient heavily depends on the design of SkyDrive's HTML pages, even small design or structural changes could easily break partially or completely this library - please keep this in mind when you are about to use it in critical/billable projects!.

How to use it?

Check the samples delivered by the source code for examples.
Additionally, you can check related project Total Commander SkyDrive File System Plugin.

Applications using SkyDrive .Net API Client

- Total Commander SkyDrive File System Plugin (.wfx)
- SkyDrive Synchronizer

New Post: A Bug Found

ghollosy — Mon, 22 Feb 2010 09:16:06 GMT

Hi,

Could you share me (make it public) a folder (set up me a test environment) where I could run/test the API to find out what can be wrong with the API?

Just send me your CID here or directly by contacting me, and I try to fix the API.

Hi,

It's a library, you don't need to install it, just add HgCo.WindowsLive.SkyDriveWebClient.dll (from the latest release) as a reference to your .net project.

If you're not a .net developer, this library is not for you. You need an application that provide you the required SkyDrive features, like the related project Total Commander SkyDrive File System Plugin, perhaps this is what you were looking for.

Commented Issue: Ability to get actual download url [3601]

ghollosy — Wed, 17 Feb 2010 14:37:03 GMT

It would be nice if it was possible to get the actual download url, currently it only have the "view" url, which that page then allows you to download the file. A direct link to download the file would be a great improvement.

Latest release (v0.8.9) contains a solution for providing DownloadUrl (if available) when using GetWebFolder, GetWebFile or GetWebFolderItem.
