• Software Development for Windows Vista UnauthorizedAccessException when using MSDTC

  Hello everyone, We have a 3-tier application, the client, the server and the databaser server. It was developed using C# 2.0 and .Net 2.0, the database server is MS-SQL 2000 and we have some MSMQ in there. All 3 are located on different machines. The client is Windows XP SP-2, the application server is Windows Server 2003 SP1 and the daatabase server is also Windows server 2003 SP1. Most of the time when the client performs an operation to the application server the database gets updated and something is written to a queue. The writing to the database and queues is performed in the context of a transaction, we use the System.Transactions facilities and MSDTC. When the server performs the writing operation it 'impersonates' ...Show All

• .NET Development Ad Removal via MSHTML

  hey guys, i have an interesting quest ahead of me, i was wondering if its possible to load a website, and then parse out the ads ive been trying to look into adding ads and removing ads via MSHTML but no luck yet, can anybody show me some code or tutorials on adding ads and removing ads via MSHTML thanks for your time! I assume the web browser control gives you access to the raw HTML response stream. If so, you will then need to parse the HTML response and look for HTML IMG tags, etc that meet a specific set of criteria (ie. definition of an Ad). Since an Ad image can look (in code) just like an image from the page being accessed, you will need to come up with some heuristics to detect an Ad (perhaps look f ...Show All

• Visual Studio 2008 (Pre-release) IPv6, Teredo and WCF peer chat

  Hi, I am trying to get the WCF peer channel chat example working on IPv6 with Microsoft Teredo. I got to the point that I think my two computers, each behind an NAT, have IPv6 addresses and can ping each other with "ping6". What do I do next to make chat instances communicate to each other I am running the name resolver in one of the peers. Replacing the address field of reolver endpoint from "net.tcp://localhost/servicemodel....." to "net.tcp://3ffe:831f:4136:e378...../servicemodel..." does not work. How would a WCF application take IPv6 address Do I need to do anything to the binding I read that there is "teredoEnabled" switch for the TCPTransport element.

• SQL Server Newbie: please help with NS 2000 runtime error

  We have a new big project coming, which will use Notification Services. So, I bought a book: "Microsoft SQL Server 2000 Notification Services" by Shyam Pather and did all steps including installing NS, setting up the environment, and creating the first sample NS application (Chapter03). Every single step was successful, no errors. I am pretty sure I didn't miss anything. All went well until I copied a sampla data file into the EventsWatchDirectory. At this point, the file name almost immediately changes to EventData.xml.20060908-160948.370.err (digits are different at every attempt, but please note the extension). I open this file using Notepad, and it is the exact copy of the original .xml file: <eventData>  &nbs ...Show All

• .NET Development Naming reason for ".Net"

  Is there any naming reason for the word ".Net" What does the word ".Net" means Thanks, Benin. I worked for a company who had a tough competitor that made a large machine and called it "Compact blabla". Another one sold a machine that was slow and they called it "Ultra blabla". Around the time that MSFT started thinking about a java alternative, and couldn't just buy out Sun, they were grossly behind on jumping on the Internet band-wagon. It is surprisingly effective.

  how can we find the spacific text in the text file for eg ABC12345 ABC48587 ABC75891 acctually i want to get the 5 numbers after abc thanks you could read through each line and check the text on the fly: Dim theStreamReader as new System.IO.StreamReader(" filename.txt ") while theStreamReader.Peak() > -1 dim theCurrentLine as string = theStreamReader.ReadLine() 'current line in file is stored in the variable above, now do whatever checking it is you would like to end while of course performance will decrease if you have a big file, since you are iterating through each line. to get specific text, you could use Regex (regular expression) to do a pattern matching techniqu ...Show All

• Visual C# Object Oriented Programming

  Hi all. Im a C++ Programmer that just moved to C# and am having problems learning about classes and objects, i just cant seem to understand it. Im not sure whether i have the wrong book, so any advice and help on the best place i can learn OOP for C# from would be much appreciated. Thanks. C# syntax is too much like C++ for it's own good sometimes. A destructor contains code that is guarenteed to run at a specific time, when an item is deleted or goes out of scope. C# does not have this, no. You need to impliment the dispose/finalise pattern to clean up resources and hope your client calls Dispose, or resources are not released right away. ...Show All

• SQL Server MSDE (SQL Server does not exist or access denied.)

  Hi all, I'm getting this error message when I try to connect my MSDE database from other machine using enterprise manager application. Both of the machines are WinXP SP2. I found some solution such as using 'SQLServer Network Utility' but didn't work out for me. I even can not connect my database on my computer using TCP/IP. When I connect with name, it worked fine.
