• Commerce Server Loading And Updating The Commerce Catalog

  I would like to ask for advice on loading the Commerce catalog from an outside source. Let me first explain how we are currently doing this and ask for comment on how we could do it more effieciently as it now takes an unacceptable amount of time to load it with a lot of data. First, our site is set up for multiple stores. Somewhere around 1000 stores will be loaded into the system, currently there are a little over 300 stores. All stores share the same basic product data, or master catalog, however, not all stores sell the same products and each store has its own pricing. Therefore, we have created a BaseCatalog containing all available product data. Each store is then setup with its own VirtualCatalog which contains just the products ...Show All

• Visual Studio Express Editions Question about the Command Line and Console.write()

  Hi, I have a project that I'm working on for someone. They have a command line shell which is basically just the cmd.exe shell with a bunch of bat files in the path. However, I was asked to write a program that would take some input (in the form of arguments) and output stuff to his console. I decided to do this in c# but not I'm having an issue. When I do a Console.Write("something") it writes it to a new console window instead of from the command prompt where it was called. Basically, what I want is this: <from the command prompt>: c:\> something.exe hello everybody hi everybody! /// from something.cs: SomeMethodThatPrintsToCommandLineFromWhichIwasCalled("hi everybody") is this even possible ...Show All

• Windows Forms DGV w/ CalendarControl

  I have a DGV with a calendar control. The calendar control works fine for those rows that have an entry in the field. When clicking on the DGV to enter a new (line) entry, the default value which was in the calendar cell from the code is replaced to a NULL value. This change causes an understandable "InvalidCastException" in trying to convert the (Null) value to a date. The default value is set at the table.column database default as (CONVERT([datetime],CONVERT([varchar],getdate(),(1)),(1))). I've also tried just getdate(). --- [I'm having a second issue with the combo filter which I'll inquire after sorting the first issue. ] All help is greatly appreciated, thanks. Code for the form is: [CODE] Impor ...Show All

• Software Development for Windows Vista "GLobal" event handler (stateMachine)

  Hi I have an interface + a service which realize it. Eg i have events like OnDateChanged on this service. These event is used to drive a StateMachine which changes states accordingly. Fine. Now i want to do some preprocessing on each of these event and then redelegate the event to the workflow to do the normal processing. Is this posible to do Regards Anders Anders - Can you explain what you mean by Pre-Processing. If the Pre-Processing is outside the WF then you are talking about the complete Re-Architecture of the solution where a middle tier is added which takes care of the events coming from the service and is responsible for firing the events to the appropriate WF instance.

• .NET Development Web Service Difficulties

  Hello, I have a class library that I use to connect to, query, and update a database. I would like to interact with this class library using ASP.NET AJAX and a WPF XBap. Based on these requirements, it seems that I need to create some webservices to expose the class library. I'm very familiar with creating and consuming webservices that are defined within an ASP.NET project. However, it seems considerably more difficult within the situation I am attempting. It appears that I need to deploy my webservices (as they may be on a different server) then create some proxy classes using the wsdl.exe tool. After I have created the proxy classes, I then need to create ANOTHER .asmx file that uses the proxy class if I want to use the webservi ...Show All

  Hello, Does anybody know how to stop the Windows Desktop Search from indexing from the dos prompt Problem is: my users connect with a mobile office card through a VPN.
