• Eljdee1 c# to x86 code

  Hi Mike, how do you generated the x86 code in one of your following blog http://blogs.msdn.com/jmstall/archive/2005/09/08/il_vs_native_offset_0.aspx Thank you for your help, Visual Studio will show you the native code for jitted C# methods. (It won't however show you the IL). ICorDebug exposes the native addresses of jitted code, so any managed debugger could show that information. Vance Morrison has an excellent blog with further details and a walkthrough: http://blogs.msdn.com/vancem/archive/2006/02/20/535807.aspx ...Show All

• th3Nu11 base-method bindings incorrect when updating a referenced assembly

  I have detected some strange behaviour on overriding methods. Hopefully this is by design because if not this could be a major bug in .NET! First of all, I am developing a framework containing multiple assemblies. This framework contains several base classes that developers can descent from. When I update the framework (when fixing a bug) I used to tell customers just to delete the old assemblies and replace them with the new versions I had send them. Sometimes this did not solve the problem. Customers sometimes needed to recompile their entire project against my updated framework assemblies before the bugs disappeared. I now have discovered what causes this strange behaviour. Let me show a small code example: Version 1 of Step ...Show All

• Sweed RSAProtectedConfiguration Provider Use In Windows Forms Apps

  Hi folks, I've been developing two enterprise apps for deployment to selected users within the company. Both of the applications have sections of their App.Config files encrypted using the RSAProtectedConfigurationProvider.  It all works fine. The problem is this: These apps will be deployed to run from the network, and will not live on the user's machine. This is also true of the App.config files. What this means is that I need to be able to create and export an RSA key container to be imported on each authorized user's machine which will be used to decrypt the encrypted sections of App.config. During development, the default .NET key has been used. Once the new key has been imported, I need a way to tell the RSAProtectedC ...Show All

• EnigMa_AnGeL how to not include base class in shema

  Hello I have three classes A,B,C. B derves from A and C derives from B. I only want to include A and C in the wsdl so that the client does not see B. I tried to use the [ XmlType (IncludeInSchema = false )] on B but then C wont be included either. Even adding [ XmlType (IncludeInSchema = true )] to C wont include C. How can this be done I do not want to include B and B:s properties should not be seen in C either. Thanks Elena, Marking the base classes with [ XmlType (IncludeInSchema = false )]  will prevent those classes to be added in the wsdl. So, it is not exactly the same as CLR inheritance in the sense that you can "hide" the inheritance not including the base clases in the wsdl. Ho ...Show All

• Moskie Cryptography

  Can we decode the Hash that is generated by MACTripleDes Actually i want to send an image from client to server in the Encrypted smallest possible size. Is there any other method to do that A hash is a secure checksum of data, it cannot be "decoded". You're probably looking at encryption and compression. Compressing first will generally give you a smaller final size. Check out the System.IO.Compression namespace for built-in methods of compressing data. Check out the System.Security.Cryptography.CryptoStream for example of encrypting/decrypting data. ...Show All

• dr.acv Numeric NullValue in DataSet schema designer

  Hi, I've just ported an application from v1.1 to v2.0 of the .NET framework. The application contains a strongly typed DataSet that it uses as an internal database, this DataSet is serialised to file using the DataSet's.WriteXml() method. This file is used as the applications file type. Users of the application have various xml files created using different versions of the application. The most up to date files, created using the recent versioned application, contain more tags/fields than older files created on older versions of the application. Prior to porting over to v2.0 the missing tags in older files where filled using the column's NullValue property. This occured for all data types. For example if column ...Show All

• Goh Wah Excel and SQL Server

  How do I read an excel spreadsheet in vb.net and insert the records from the spreadsheet into a SQL database Two questions: 1. Where would I find the documentation for HDR and IMEX etc 2. HDR=Yes isn't working for me. I can't get the first row from Excel with the column names. Any idea what might be wrong NoSpam_Glider_Guider@Yahoo.com.NoSpam The HDR argument will determine whether the first row in the Worksheet is used as column names in your DataSet/DataTable. If the value is YES then the column names will correspond to those found in the first row of the Excel Worksheet or Range. If the value is NO then the column names for your DataSet/DataTable will default to F1, F2, F3, etc. ...Show All
