• Visual Studio filtering reference dropdowns in the propertygrid

  I have a basic model, where I have a Table class, a Key class, a Field class, and a FieldReference class. The idea is that this can be used to model a database structure. Tables may have multiple Fields, and Tables may also reference multiple Keys. Each Key may contain multiple FieldReferences, and a FieldReference can have 1, and only 1 Field selected from a dropdown in the propertygrid. My problem, is that the dropdown for the Field component of the FieldReference lists ALL Field instances in the entire diagram, I need it to be filtered to show just the set of Fields that belong to the Key classes owning Table class. This is becuase its not possible for a tables PrimaryKey to contain columns from a different table... An ...Show All

• .NET Development System.Net.Socket disconnect problems

  Hi, I've done some searching but haven't managed to find an answer - hopefully this is the correct place to post. A group of us are writing an internet chat protocol with associated server and client. The server is written in VC++, and goes through a specific chain of events if the OnClose() function of one of the CAsyncSockets is called. For one of the clients in development (realbasic on mac OS X) this works fine - they close the connection at their end, and the server picks it up. However, for the VB.NET version of the client we are having problems. No matter how we disconnect, the server doesn't realise that the client has gone. I can only assume this is a .NET related issue as the other client does work. Has anyone got ...Show All

• Visual Basic VB computing wrong value during execution

  I am receiving the wrong result when I perform the following computation using VB.NET 2005. MM = CDbl (LoCursr - 1) / CDbl (HiCursr) LoCursr and HiCursr are both dimensioned as Integers and have values of 85 and 87 and are passed into this subroutine as ByRef values. MM is a local variable declared as a double. If I execute this statement in the immediate window, I get the correct result of 0.96551724137931039 However, when this statement executes normally, I receive a result of 0.96551722288131714 which I also get if I execute Cdbl(Csng(84/87)) in the immediate Window. I've tried storing the LowCursr and HiCursor values in Doubles prior to doing the computation, but that did not correct the problem. Is there a se ...Show All

• Visual Studio Adding commands to the context menu in the editor

  Hi. I have developed a language service for a custom language using the MPF, and now im trying to add som extra choices to the context menu in the editor-window. I know i can make my own context menus by using a custom editor instead of the core editor, but if im not mistaken, then I would lose all support for syntax coloring, squigles, outlining, highlighting etc. which is utilized in my language service (please correct me if im wrong) Is there some way of accessing the core editors context menu, and add commands to it It would be nice to be able to remove commands aswell. Or is there some way of extending the core editor and replace its context menu Any help on the subject would be appreciated Frank. ...Show All

• SQL Server Changing the "From" line in e-mail deliveries

  I am wondering if there is a way to change the "From" line in e-mails when sending out e-mails via subscriptions (using Reporting Services 2005) As an example, in the rsreportserver.config file I have an e-mail account specified within the <From> tag that all mails are sent from.

  I'm new for ssas and I'm studying NS samples,i found all the subscribers and subscriptions are created manully,my app have millions of subscribers and many different kinds of subscriptions,so how to create those objects through reading data from tables Much appreciate for your reply In SSNS 2000, subscribers, devices, and subscriptions have to be created using the SSNS API using a programming language like C#, VB.NET, or VBScript. In SSNS 2005, we know have some views that can be used to create those rows in the database.

• Visual C# Class constructor with null Date parameter

  I am trying to figure out the best work around for the following senario. I have an application that accesses a SQLServer DB. I have a "Job" class that represents a Job our company is working on. The constructor for a Job looks like... public Job(string JobName, int CustomerID, DateTime DueDate); There is a "Due Date" field in the Jobs table in the DB that allows nulls (not all jobs have a due date). When I pull a record from the DB and create a Job object with the record, I get an error is the DueDate field is null. Obviously you can't convert null to a DateTime value type. Now, the only solution I can think of is to pass a date like "1/1/1900" into the db if the user leaves the DueDate blank, and display th ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Setting Effect.Parameters on the fly?

  I am looking to setup the ability to set values of parameters in an Effect on the fly. Right now I have a dictionary of type <string, object> which is setup similar to how Effect Parameters are. Effect.Parameter[string].SetValue(...) doesn't take type object though. Maybe I am missing something but is there a way I can do this SetValue has a load of overloads so it does not have to cast it to the correct type, which makes a lot of sense. What is preventing you from setting them on the fly using the normal way ...Show All
