• Visual Basic If I want to upgrade my program of VB6.0 to the program have net application, is it the VB.net is my only choice?

  Please help to give some advise, My program is developed by using VB6.0, and now I need to upgrade the program that can support the online application or online transaction. So is it the VB.Net / VB 2005 are the only and the best choice Because some of the people are mentioned that the C#'s performance speed and stable will better then the VB, it is true if I am using the VB.Net to develop, what is the strong point of this new version of VB 2005 uses version 2 of the .NET framework and has LOTS of new features. The upgrade price will be cheaper then buying just 2005 alone, contact the vendor of your choice for more details. ...Show All

• .NET Development Session across different web sites

  Hi, I'm trying to create a shared session across 2 different web sites/application. How can i retrieve the session (details) from the first application, and then replace it with the session of the second application I'm using state server to store my session details. Regards Danny Dear Danny, In order to share Session across 2 different web applications, you have to store session state in an ASP.NET application with out-of-process method, When you use this option, session state is stored in the Aspnet_state.exe process; this process runs as a service and may be located on a separate state server. Using a state server allows applications running in a Web farm to access shared state inform ...Show All

• Visual Studio Express Editions Serial port problem

  Hi All I have an application that monitors a com port for incoming messages. I recieve a message every three seconds which is coming through fine but when I close the port my application keeps on closing. Anyone perhaps know why I am not getting any error messages at all. Thanks in advance Ross This is a fairly common problem with the SerialPort.Close() method. It is prone to deadlock, causing your program to hang. First, make sure you open the port only once, at the start of your program. Check this thread for reference. ...Show All

• .NET Development Can a DataSet tell if tables in the SQL database have been updated?

  I've got a client-server app that hooks up to a SQL Server 2000 database. So far everything works well but this application is not the only user of the database. We have an Access front-end that also hooks up to these tables. (The .Net application is replacing another application that goes to the same tables and will eventually also replace the access front-end but that's at least a year off) My server application has a DataSet that mirrors the SQL tables. This way I have local copy of the table data I can work with programatically (and more quickly) and send updates to the SQL tables as necessary. This arrangement works well but I'm concerned about how to tell if the Access front-end has changed any of the SQL tables since I did the Da ...Show All

• Visual Studio 2008 (Pre-release) Custom DependencyProperty not receiving change notifications

  I am making a custom control that has a DependencyProperty of type IEnumerable. Everything seems to work fine except for change notifications. I'm testing using an ObservableCollection bound to my property. If I add or remove items from the ObservableCollection, my DependencyProperty's change callback is never called. For testing I bound my collection to a generic ListBox as well and that handled the collection changes as expected. How can I make my property respond to change notifications from the bound collection Here is the relevant code... public static readonly DependencyProperty MyDPProperty = DependencyProperty .Register( "MyDP" , typeof ( IEnumerable ), typeof ( MyControl ), ...Show All

• Software Development for Windows Vista Requesting Admin Rights without COM

  I have been trying to read over many of the articles concerning elevated priviledges in an application, but am a bit lost.  http://msdn.microsoft.com/library/default.asp url=/library/en-us/ietechcol/dnwebgen/protectedmode.asp http://windowssdk.msdn.microsoft.com/en-us/library/ms679687.aspx Those two of the main articles I have been trying to understand.  I know I can create a COM class that is defined in the registry and set it's elevation values there, then create it through CreateInstance.  The first article I am almost completely lost on (maybe it doesn't have anything to do with what I want ).
