  • .NET Assembly Diff / Compare Tool - What's available?

    - by STW
    I'd like to be able to do a code-level diff between two assemblies; the Diff plug-in for Reflector is the closest thing I've found so far, but to compare the entire assembly is a manual process requiring me to drill-down into every namespace/class/method. The other tools I've found so far appear to be limited to API-level (namespaces, classes, methods) differences--which won't cut it for what I'm looking for. Does anyone know of such a tool? My requirements (from highest to lowest) are: Be able to analyze / reflect the code content of two versions of the same assembly and report the differences Accept a folder or group of assemblies as input; quickly compare them (similar to WinMerge's folder diff's) Quick ability to determine if two assemblies are equivalent at the code level (not just the API's) Allow easy drill-down to view the differences Exporting of reports regarding the differences (Personally I like WinMerge for text diffs, so an application with a similar interface would be great)

    - by user225269
    I have this, birthday selection which is in 3 combobox, 1 for month, 1 for day and 1 for year. But my database table has only this birthday attribute(no year, month or day).

  • Query Access and VB.NET

    - by yae
    Hi all: I have 2 tables: "products" and "pieces" PRODUCTS idProd product price PIECES id idProdMain idProdChild quant idProdMain and idProdChild are vinculated with the table: "products". Other considerations is that 1 product can have some pieces and 1 product can be a piece. Price product equal a sum of quantity * price of all their pieces. EXAMPLE: TABLE PRODUCTS (idProd - product - price) 1 - Computer - 300€ 2 - Hard Disk - 100€ 3 - Memory - 50€ 4 - Main Board - 100€ 5 - Software - 50€ 6 - CDroms 100 un. - 30€ TABLE PIECES (id - idProdMain - idProdChild - Quant.) 1 - 1 - 2 - 1 2 - 1 - 3 - 2 3 - 1 - 4 - 1 WHAT I NEED? I need update the price of the main product when the price of the product child (piece) is changed. Following the previous example, if I change the price of this product "memory" (is a piece too) to 60€, then product "Computer" will must change his price to 320€ How I can do it using queries? Already I have tried this to obatin the price of the main product, but not runs. This query not returns any value SELECT Sum(products.price*pieces.quant) AS Expr1 FROM products LEFT JOIN pieces ON (products.idProd = pieces.idProdChild) AND (products.idProd = pieces.idProdChild) AND (products.idProd = pieces.idProdMain) WHERE (((pieces.idProdMain)=5));

  • ASP.NET Membership C# - How to compare existing password/hash

    - by Steve
    I have been on this problem for a while. I need to compare a paasword that the user enters to a password that is in the membership DB. The password is hashed and has a salt. Because of the lack of documentation I do not know if the salt is append to the password and then hashed how how it is created. I am unable to get this to match. The hash returned from the function never matches the hash in the DB and I know for fact it is the same password. Microsoft seems to hash the password in a different way then I am. I hope someone has some insights please. Here is my code: protected void Button1_Click(object sender, EventArgs e) { //HERE IS THE PASSWORD I USE, SAME ONE IS HASHED IN THE DB string pwd = "Letmein44"; //HERE IS THE SALT FROM THE DB string saltVar = "SuY4cf8wJXJAVEr3xjz4Dg=="; //HERE IS THE PASSWORD THE WAY IT STORED IN THE DB AS HASH string bdPwd = "mPrDArrWt1+tybrjA0OZuEG1P5w="; // FOR COMPARISON I DISPLAY IT TextBox1.Text = bdPwd; // HERE IS WHERE I DISPLAY THE return from THE FUNCTION, IT SHOULD MATCH THE PASSWORD FROM THE DB. TextBox2.Text = getHashedPassUsingUserIdAsSalt(pwd, saltVar); } private string getHashedPassUsingUserIdAsSalt(string vPass, string vSalt) { string vSourceText = vPass + vSalt; System.Text.UnicodeEncoding vUe = new System.Text.UnicodeEncoding(); byte[] vSourceBytes = vUe.GetBytes(vSourceText); System.Security.Cryptography.SHA1CryptoServiceProvider vSHA = new System.Security.Cryptography.SHA1CryptoServiceProvider(); byte[] vHashBytes = vSHA.ComputeHash(vSourceBytes); return Convert.ToBase64String(vHashBytes); }

  • ASP.Net MVC Outbound Route Matching Problem When Using ActionLink

    - by Godders
    Hi there, Hoping for some help after reading into MVC routing and not coming up with the answer myself. I have the following routes registered: public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( null, "YourFeedback/Article/{resourceId}", new { controller = "YourFeedback", action = "Index", contentTypeId = new Guid(ConfigurationManager.AppSettings["ArticleLibraryId"]) }); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); } I have the following ActionLink in an aspx view: <%=Html.ActionLink("Your Feedback", "Article", "YourFeedback", new { resourceId = Model.ContentId.ResourceId }, new { @class = "yourFeedback" })%> My understanding of MVC routing is that this would render a anchor link with href of "/YourFeedback/Article/101" where 101 comes from Model.ContentId.ResourceId. Yet the anchor link href is rendered as "YourFeedback/Article/resourceId=101". Any ideas where I'm going wrong? Thanks in advance.

  • How to mask DLL in .NET ?

    - by ytrewq
    Let's say I have a DLL that provides math calculus functions. To use it, I include the using Colhq.Math.Basic; namespace. How could I use it by adding a statement like using Blala.Functions.Math; ? So how could I use everything (methods, enums, etc.) from a DLL by using a different namespace ? Is there a one-shot way to wrap or mask a DLL ?

  • Sending email via GMail in .NET

    - by VP
    I am getting the following error when I try to send an email in my C# program. I am using Visual Studio 2008 on windows 7. I would paste my code first and then the error: class email_log_files { private string login_username = "my_gmail_id"; private string login_password = "my_gmail_password"; public void send_email() { string src_address = "[email protected]"; string dest_address = "[email protected]"; try { MailMessage email_msg = new MailMessage(); SmtpClient email_client = new SmtpClient(); email_msg.From = new MailAddress(src_address); email_msg.Sender = new MailAddress(src_address); email_msg.ReplyTo = new MailAddress(src_address); email_msg.To.Add(dest_address); email_msg.Subject = "Test"; email_msg.Body = "Body of the message"; NetworkCredential credentials = new NetworkCredential(login_username, login_password); email_client.Credentials = credentials; email_client.Host = "smtp.gmail.com"; email_client.Port = 465; email_client.EnableSsl = true; email_client.Send(email_msg); Console.WriteLine("Message Sent Successfully!!"); Console.ReadLine(); } } } And the error message is as follows: The operation has timed out. Why is it always timing out? I am sure that I have the correct smtp server address and port number for gmail as I have configured my outlook with the same. Any help or ideas?

  • .Net Dynamically Load DLL

    - by hermiod
    I am trying to write some code that will allow me to dynamically load DLLs into my application, depending on an application setting. The idea is that the database to be accessed is set in the application settings and then this loads the appropriate DLL and assigns it to an instance of an interface for my application to access. This is my code at the moment: Dim SQLDataSource As ICRDataLayer Dim ass As Assembly = Assembly. _ LoadFrom("M:\MyProgs\WebService\DynamicAssemblyLoading\SQLServer\bin\Debug\SQLServer.dll") Dim obj As Object = ass.CreateInstance(GetType(ICRDataLayer).ToString, True) SQLDataSource = DirectCast(obj, ICRDataLayer) MsgBox(SQLDataSource.ModuleName & vbNewLine & SQLDataSource.ModuleDescription) I have my interface (ICRDataLayer) and the SQLServer.dll contains an implementation of this interface. I just want to load the assembly and assign it to the SQLDataSource object. The above code just doesn't work. There are no exceptions thrown, even the Msgbox doesn't appear. I would've expected at least the messagebox appearing with nothing in it, but even this doesn't happen! Is there a way to determine if the loaded assembly implements a specific interface. I tried the below but this also doesn't seem to do anything! For Each loadedType As Type In ass.GetTypes If GetType(ICRDataLayer).IsAssignableFrom(loadedType) Then Dim obj1 As Object = ass.CreateInstance(GetType(ICRDataLayer).ToString, True) SQLDataSource = DirectCast(obj1, ICRDataLayer) End If Next EDIT: New code from Vlad's examples: Module CRDataLayerFactory Sub New() End Sub ' class name is a contract, ' should be the same for all plugins Private Function Create() As ICRDataLayer Return New SQLServer() End Function End Module Above is Module in each DLL, converted from Vlad's C# example. Below is my code to bring in the DLL: Dim SQLDataSource As ICRDataLayer Dim ass As Assembly = Assembly. _ LoadFrom("M:\MyProgs\WebService\DynamicAssemblyLoading\SQLServer\bin\Debug\SQLServer.dll") Dim factory As Object = ass.CreateInstance("CRDataLayerFactory", True) Dim t As Type = factory.GetType Dim method As MethodInfo = t.GetMethod("Create") Dim obj As Object = method.Invoke(factory, Nothing) SQLDataSource = DirectCast(obj, ICRDataLayer) EDIT: Implementation based on Paul Kohler's code Dim file As String For Each file In Directory.GetFiles(baseDir, searchPattern, SearchOption.TopDirectoryOnly) Dim assemblyType As System.Type For Each assemblyType In Assembly.LoadFrom(file).GetTypes Dim s As System.Type() = assemblyType.GetInterfaces For Each ty As System.Type In s If ty.Name.Contains("ICRDataLayer") Then MsgBox(ty.Name) plugin = DirectCast(Activator.CreateInstance(assemblyType), ICRDataLayer) MessageBox.Show(plugin.ModuleName) End If Next I get the following error with this code: Unable to cast object of type 'SQLServer.CRDataSource.SQLServer' to type 'DynamicAssemblyLoading.ICRDataLayer'. The actual DLL is in a different project called SQLServer in the same solution as my implementation code. CRDataSource is a namespace and SQLServer is the actual class name of the DLL. The SQLServer class implements ICRDataLayer, so I don't understand why it wouldn't be able to cast it. Is the naming significant here, I wouldn't have thought it would be.

  • difference between DataContract attribute and Serializable attribute in .net

    - by samar
    I am trying to create a deep clone of an object using the following method. public static T DeepClone<T>(this T target) { using (MemoryStream stream = new MemoryStream()) { BinaryFormatter formatter = new BinaryFormatter(); formatter.Serialize(stream, target); stream.Position = 0; return (T)formatter.Deserialize(stream); } } This method requires an object which is Serialized i.e. an object of a class who is having an attribute "Serializable" on it. I have a class which is having attribute "DataContract" on it but the method is not working with this attribute. I think "DataContract" is also a type of serializer but maybe different than that of "Serializable". Can anyone please give me the difference between the two? Also please let me know if it is possible to create a deepclone of an object with just 1 attribute which does the work of both "DataContract" and "Serializable" attribute or maybe a different way of creating a deepclone? Please help!

  • ASP.NET MVC download image rather than display in browser

    - by RSolberg
    Rather than displaying a PNG in the browser window, I'd like the action result to trigger the file download dialogue box (you know the open, save as, etc). I can get this to work with the code below using an unknown content type, but the user then has to type in .png at the end of the file name. How can I accomplish this behavior without forcing the user to type in the file extension? public ActionResult DownloadAdTemplate(string pathCode) { var imgPath = Server.MapPath(service.GetTemplatePath(pathCode)); return base.File(imgPath, "application/unknown"); }

  • asp.net mvc custom routes with multiple submit buttons

    - by dangerisgo
    So I have a custom route as such: routes.MapRoute( "Wizard", // Route name "Wizard/{page}", // URL with parameters new { controller = "Wizard", action = "Index" } // Parameter defaults ); and have the following on my View: <% Html.BeginForm("Continue", "Wizard"); %> <input type="submit" value="Continue" name="Continue" /> <% Html.EndForm(); %> In which I want to call this function: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Continue(string Number, string Rev) { (...) } but in turn when that button is pressed always calls the postback Index rather than the one I want. If I remove the custom route, it calls my function, but what I want to be displayed in the address bar is: localhost:xxxx/Wizard/1 where the number at the end is the page (div shown) of the wizard either 1, 2, 3, or 4. So is there something I'm missing or can it not be done? Thanks.
