Architecture Online/Offline mode, abstracted
We are planning an enterprise app. The basic setup will consist of a winforms client that will connect via remoting to a centralized app-server over a vpn. We must be able to provide basic functionality even in the event of a network outage. The plan is to have a local database that is a stripped down version of the main database. The local database will get updated periodically so it stays roughly in synch with the main database. The client will be able to switch between online (main database over remoting) and Offline (local database via direct mdac). My initial design is to go with a layer of service interfaces, and implement it twice ...Show All

SQL Server Sending Messages with ADO.NET 1.0
Hi, after some tooling round, googling, hair-pulling etc i have some prototypes of a simple C#.NET 1.1 console app which can now post a message to my yukon SB service i set up. It calls an internal activation stored proc to store the message in a simple table. The problem i had was in the connection string "... Asynchronous Processing=true". The run-time throws an exception moaning about the Asynchronous Processing=true bit. So i just omitted it completely... Seems to work fine and as expected. I can post a message, my app exits, and the dummy stored proc (which i deliberately made enter a loop updating the table thousands of times ...Show All
Windows Forms ClickOnce not working for customer
I'm baffled by this - myClickOnce app installs and updates perfectly (across the internet) on my development PC, but does not work on any of my client's PCs. The only significant difference being that they use a proxy server to access the internet, but this is of course configured into IE, which I presume does impinge on ClickOnce. The proxy server does not require authentication. The error message is pretty much always the same - and doubly confusing at that, since it seems to indicate the program folder cannot be created, and yet if I search the hard disk I can find the whole application intact (but not at the location referenced in the lo ...Show All

Game Technologies: DirectX, XNA, XACT, etc. Good source (s) to learn Direct X (c++)
Hi, I have begun programming with DirectX and C++ for a while now (not a very long while =)) I've read the 6 tutorials that comes with the SDK and understand them quite well, but where do I go from here Most interesting info I find about DirectX programming for newbies is in managed, but, since I already can programme nicely with C++ (console and windows) I think that would be some kind of a step back, dunno why really... but is there any good sources for me to read and learn Direct X using C++ that would fit my describtion. would be awesome to move on from rendering differend objects in screen. =) I don't really know...

Visual FoxPro editbox programmatic change
I am looking for an easy way to determine if I've made interactive change in an editor box. The issue is that there are about 16 controls on a container, they are initialized from a table record thus their values at activate time generally are not trivial default. I have to save the changes with a SAVE button if I made any but I want this button's click method to quickly determine which control values have been changed. I do not want to do REPLACE for the fields with values that haven't been changed. In case of simple controls like a combobox I can store the initial value in Tag property and do the comparison programmatically. Sometimes t ...Show All
