C# Web Service / Win form download file application

Create a C# (VS 2008 based) web service and corresponding winform app to send and receive files from the web service to the winform application.? The following lists the flow of communication to/from the web service: 1. Winform sends request to winservice 2. Winservice responds with list of files to download 3. Foreach file to download ? A) Winfom initiates download ? B) File is sent down in 'chunks' ? C) Winform responds to server that file is received successfully after comparing size recieved from webservice ? D) next file 4. Winform sends confirmation that all files have been received Use the model discussed in the following article as a place to start: ? ? <[login to view URL]> You can use any .NET framework class available in .NET version 3.5 but you cannot use any libaries already developed on the market.? I need to be able to redistribute this application in one of my companies products and not pay any royalty fees. ## Deliverables Create a C# (VS 2008 based) web service and corresponding winform app to send and receive files from the web service to the winform application.?

I need to be able to redistribute this application in one of my companies products and not pay any royalty fees. Tasks to be performed: 1. Create web service named (in the namespace: [login to view URL]) CRCUpdate (name of the .asmx file as well as the class).? The web service will have the following public methods: Methods: ? A) LoginAndValidate (string xmlData):? Method will be used to validate the requester and send back a list of files for the client app to download. ? B) DownloadFile (string fileRequest):? Method to request and initiate the download of a file.? ? C)? There will probably be more methods to expose/enable download capability. 2. Create desktop sample app: TestCRCUpdate.? The desktop application will have a single main dialog with one option to specify the time of day when the given 'watcher' thread will communicate with the web service.? The UI will have a time picker and a button that will toggle between Run Thread and Stop Running Thread.? Create a background thread that will communicate with the web service at the specific time of day and begin the process of communicating and receiving files. 3. Create a test case where the test client application requests and downloads 6 files: 2 text files, 2 image files, and 2 .exe files (see attachment for samples - 1 file must be 50 megabytes large to confirm the chunking works with very large files - no sample will be provided). All code for all methods must be wrapped in try/Catches (see coding standards below for details). Also, you must follow the following coding standards.? NOTE:? CODE WILL NOT BE ACCEPTED IF THE CODE DOES NOT CONFORM TO THE FOLLOWING CODING CONVENTIONS/STANDARDS: CODING STANDARDS/REQURIEMENTS: Classes_____________________________________ S1) All classes will start with a capital letter S2) All classes will have a comment at the end brace with the classes name Example: public class MyClass { }// MyClass Methods______________________________________ S3) ALL method's first letter will begin with a capital letter and words in the name will begin with a capital letter. Example: public class MyClass { ? public void CorrectMethodName () ? { ? } }// MyClasss S4) All methods will have ONE try catch block and the catch will use [login to view URL] method to handle the exception (NOTE: A DLL called [login to view URL] will be provided to include in all projects - NOTE: contained in attachment [login to view URL]). S5) All methods will have a comment at the end brace with the method name. Example: ? public void CorrectMethodName () ? { ? }//CorrectMethodName S6) Variables and parameters will start with a lower case letter. Example: ? public void CorrectMethodName (string correctParamName) ? { ? }//CorrectMethodName S7) All return values will be done at the end of the method once ? public string CorrectMethodName (string correctParamName) ? { ? ? string res = null; ? ? ? ? ...various code, no mid-method returns? ? ? return res; ? }//CorrectMethodName S8) All methods will have the standard C# comment header Example: // <summary> /// Checks if a parameter is null /// </summary> /// <param name="o">Varible to check nullness</param> /// <returns>True if parameter is null</returns> public bool IsThisParamNull (object o) { ? bool res = false; ? try ? { ? ? res = (o == null); ? } ? catch(Exception ex){[login to view URL](ex);} ? return res; }// IsThisParamNull Member Variables and Properties__________________ S9) All public member variables and properties will begin with a capital letter S10) All private variables will begin with a lower case letter. S11) All properties will have a comment at the end brace with the property name Example: public class MyClass { ? public string MyID ? { ? ? get{return [login to view URL];} ? ? set{[login to view URL] = value;} ? }// MyID ? private string myID; }// MyClass
