  • why does vb not support multiple inheritance?

    - by isolatedIterator
    I've seen some discussion on why c# does not implement multiple inheritance but very little as to why it isn't supported in vb. I understand that both c# and vb are compiled down to intermediary language and so they both need to share similar restrictions. The lack of multiple inheritance in VB seems to have been given as one reason for the lack of the feature in dot net. Does anyone know why VB doesn't support multiple inheritance? I'm hoping for a bit of history lesson and discussion on why this was never considered for VB.

  • Objective C BitConverter Equivalent

    - by user352891
    Hi there, I'm wondering if there is an Objective C equivalent to .Net's BitConverter.GetBytes() method. For example, in C#, I can write something like this: byte[] lengthPrefix = BitConverter.GetBytes(message.length); What would the equivalent be in Objective C? Some example code would be greatly appreciated. Thanks in advance.

  • How to insert a DataTable with existing Key to a SQL Server Table.

    - by user296575
    I am working with VB.NET.. i have a DataTable called "QUESTION", containing 3 fields: QuestionNumber (unique integer key) QuestionText QuestionType In my SQL Server database I created a Table called "QUESTION" with the same fields. QuestionNumber is defined as integer unique key, auto increment Now, when i make a bulk copy to insert the DataTable into the SQL Server, the database overwrites my QuestionNumber from the DataTable and generates new ones (starting from 1 increment 1). How do i have to change my database setup, that the original QuestionNumbers are copied into the database?

  • Deploying XBAP as an ActiveX

    - by Kaveh Shahbazian
    How can I deploy a XBAP to a client machine as an ActiveX (Which I can instantiate and use from JavaScript, passing parameters to it, getting parameters from it, etc)? This is part of an ASP.NET site, and will be in full trusted mode (I have solved that part, actually I have implemented a test XBAP that can edit a text file on local hard drive of a client machine). Thanks

  • Range subtraction in the Excel Object Model

    - by mcoolbeth
    When using Excel Interop libraries from .NET, I can find a Range object representing the cell offset from Range X by calling something like. Range Y = X.Range[2,3]; But what should I do to perform the inverse operation, ie: I have two Range objects, A and B, and I would like to find out by how many rows/columns B is offset from A. Does anyone know the easiest way to do this? Is there a library function? Thanks.

  • Built-in precedence in Expression Trees for math?

    - by jdk
    I'm unable to find the .NET FCL built-in concept of precedence to leverage while constructing Expression Trees. Ref System.Linq.Expressions Namespace. Is this something that must be handled manually in code, or is it somehow implicit and I'm not recognizing it (e.g. maybe through helper methods or classes)? I want to apply it to math operations to ensure 3 + 5 * 10 results in 53 instead of 80.

    - by Chathuranga Chandrasekara
    I am in a need of programatically convert an Word-XML file into a RTF file. It has become a requirement, because of some third party libraries. Any API/Library that can do that? Actually the language is not a problem because I just need to work done. But Java, .NET languages or Python are preferred.

  • Is there any performance advantage to using DirectorySearcher over SearchRequest for LDAP queries.

    - by WayneC
    I understand that System.DirectoryServices is a "layer above" System.DirectoryServices.Protocols and abstracts some of the complexity. Are there any other advantages, performance or otherwise, to using System.DirectoryServices.DirectorySearcher vs. System.DirectoryServices.Protocols.SearchRequest for LDAP queries from .NET. What criteria would cause you to use one approach over the other?
