• SQL Server Definition of 'Persistent Data'

  What is the definition of 'Persistent Data' as related to the definition of a RDBMS thx, Kat Persistent Data is data that stays around after the application has terminated. In the case of an RDBMS, it would refer to data which had been committed to tables. It would not refer to items stored in temporary tables or units of work that the server accumulated while processing a query -- work tables. It would also not refer to variables defined and used during processing. ...Show All

• .NET Development Interop question

  Hi, I created a com visible class in c# 2.0. I'm trying to instantiate it from javascript from 2 different browsers and everything works fine.

• Visual Basic Drag & Drop icons from Desktop onto control

  Hi all, I have written a menu app which I have to browse for files, to tell it the file name / path. I would like to Drag & Drop icons onto the form / control from the windows desktop. I have a basic understanding on how to drag/drop from 1 control to another (both on the form ofcourse), but when i try to drag an item from the desktop the mouse pointer changes to a circle with a line through it. I am assuming that Vb only lets you drag items from the form onto iteself. Is this correct Code sample would be appreciated. Thanks in advance. Ok great thanks. That worked a treat. But is there anyway to "package" this file inside my project and use it internally rather than externally so that I don't have ...Show All

• Visual Studio 2008 (Pre-release) TOP/LIMIT Support for LINQ?

  Is there (or will there be) any support for limiting a result Something like var pagedData = from ds in datasource rows 50 to 100 select ds; Regards, Daniel You have at least 3 options for profiling. 1) Use SQL Profiler with SQL Server. 2) The datacontext exposes a .Log method which attaches to a stream and outputs the generated queries to that stream. You can easily attach it to the console window using the following: db.Log = Console.Out 3) The MAY CTP includes a visualizer which you can use during debugging to examine the LINQ to SQL generated query. It also allows you to modify the query and test fetching the results. To check this, put a breakpoint on your foreach and hov ...Show All

• .NET Development How do I Set Version number for ASP.net custom control

    Hi I've developed a Custom Control in ASP.Net 2.0 It's great in everyway but the version number.  I can't figure out how to change/set it.  It's currently verion 0.0.0.0. I search MSDN and it only gave me help for C# and C++ ASP.net apps.  There's more than one way to do it, but NONE seem to work with Visual Basic, the langauge I developed the Control in. C# , C++ and J# have /V as an optional parameter for the complier to set a version, the VB complier doesn't Can anyone help   I don't care where or how I set it, just that I can. Because custom ASP controls we've built in C# have got a version but not the custom ASP controls in VB!   Thanks ...Show All

• Smart Device Development DCOM source code?

  Hi, we are trying to find a way to access a bag printing device in our plant that uses the OPC standard. We want to change the data that is being printed. The OPC Standard was created (with the help of Microsoft) to use DCOM to allow Windows applications to communicate with such devices. However, due to various project constraints, we are forced to use an AS/400 application for the communication to the printer instead. Therefore, it has been suggested to me that I try to determine the data string (preamble, data, and postamble) that is actually being sent in the "Windows application to printing device" scenario so that we can replicate this in AS/400 code. We would then send the data string via the AS/400 application to the I ...Show All

• Visual Studio 2008 (Pre-release) Unified way to add and remove child element

  Hello, I would like to ask couple of questions: 1) Is there a unified way to add element as a child to a parent Currently I am achieving it like this, but not sure it this is a right way to do it: IAddChild parent = LogicalTreeHelper.GetParent(child) as IAddChild; if (parent != null) parent.AddChild(child); 2) Is there a unified way to remove element from its parent children collection My current method is ugly enough to look for a better one :) DependencyObject parent = LogicalTreeHelper.GetParent(child); if (parent is ContentControl) ((ContentControl)parent).Content = null; if (parent is ItemsControl) ((ItemsControl)parent).Items.Remove(child); if (parent is Panel) ((Panel)parent).Child ...Show All

• Visual Basic list of deprecated methods and theur vb2005 equivalent

  Does anyone know a website or webpage wherein they supply a list of visual basic 6 methods, functions, and such, and provide the visual basic 2005 equivalents I grew tired of trying to upgrade the functions I need using the VB6 upgrader tool.

• SQL Server Check FTP file date

  First I want to thank everyone that has given help to me and everyone else with the issues involving migrating to 2005... Thanks alot.. Now for the problem. I am looking for (an not finding anything of help) to check the date of a file on an ftp server. A file always exists but once a month the day changes. I would just download the file and check it locally but the files are several hundred megs in size so that would be inefficient.
