• .NET Development Access the data available on internet and use it in my web application

  Hiii, I want to list the prices of some products available on the internet everytime i open a web page in my application.. ex: I want to list all the printers available and their prices from internet in a datagrid on my page. Is it possible if so how.... There's the poor man's approach: Screen scrape the interesting web sites by loading the web pages and parsing their HTML sources. This is tedious, fragile, and error prone, because even minor changes to the HTML source my break your price lookup code. And there's real application integration, e.g. using Web Services to obtain the latest prices. This of course requires t ...Show All

• Visual Studio 2008 (Pre-release) Trips to the database

  I have a general performance question that needs clarification. Assuming an object graph of Customer, Orders, OrderDetails and assume I am retrieving one customer with 10 orders and each order has 5 orderdetails, how many trips to the database will be required Is it 3 or 12 Thanks, Dave Foderick Deferred execution will run more queries, but will only do it when needed. This is the default for most things you have seen, most likely. For example, in the following LINQ query, a SQL query will be fired for each customer to get the orders for that customer: var q = from c in db.Customers select new {c.CustomerID, c.Orders}; ObjectDumper.Wr ...Show All

• SQL Server Real Time ROLAP different then ROLAP

  What is the benefit of setting the proactive cache to Real Time ROLAP. Wouldn't this be the same as ROLAP. Confused on why there is such an option. Books online doesn't seem to answer it clearly. Proactive caching adds the ability to automatically detect changes in source data and update Analysis Services objects appropriately. In the case of Real-Time ROLAP (which was also an option in AS 2000), the AS server can detect data changes (via events, polling or client-initiated notification) and invalidate its in-memory cache - without proactive caching, explicit processing would be needed to dro ...Show All

• Visual Studio Tools for Office Wrap VSTO Projects in other Projects?

  I am looking for suggestions or direction on a project. I have come across a couple of samples that relate to Office Projects that I want to wrap inside of a large VS.Net project. My problem is this, from what I can see, Office Projects connect to one document each, but in my case I have one dataset that feeds and builds 8-12 different document templates. I am using the WordReadWriteadoVB Sample as my framework, but need to be able to use several document templates with the same codebase. Any Suggestions or other places I can look for docs Thanks; Daivd One thing that comes to my mind is that you could add the newly bu ...Show All

• Visual C++ Poly-Threaded C++ Applications

  I have a few programs that I am converting to be threaded. At present I have a couple of programs, computer chess engines, that are threaded and work fine with Microsoft's C++ compilers. When the SMP.H #define's detect _WIN32 || _WIN64 it calls up process.h functions but on other platforms it need to use a bit map in ASM to manage the threads properly. Other considerations include inter-process communications etc. If threads dont need to speak to each other then the situation is simple, if not then some form of signalling is needed and the program becomes more complex. One program I use computes end game positions for chess, usin ...Show All

• Windows Forms ComboBox.ValueMember Question - RESOLVED

  I have a PopulateComboBox sub, in which I assign the value member for the combo box I happen to be populating. If I create a SelectedIndexChanged sub for that combo box, and try and check the ComboBox.SelectedValue, it returns DataRowView until I reassign (within that sub) the ValueMember. Is there a reason for that that I'm perhaps missing entirely It seems somewhat pointless to me to have to do this.

• Visual Studio Express Editions Dotnetfirebird

  Hi! Does anyone know if it's possible to get an report printed using the Firebird database It seems to be very good for using with embedded databases, but i can't find any good free report liberys to use with it. Does anyone know one Not aware of any free reporting tools available for .NET I'm afraid and there are no reporting facilities in any of the Express editions. Most third-party vendors seem to charge an arm and a leg for these products, which would probably explain why there isn't anything available for free. There are a couple of third-party products that are relatively inexpensive compared to C ...Show All
