• Visual Basic Intercept/Detect File Modifications (Create, Delete, Modify)

  I've checked out the FileSystemWatcher sample from MSDN. It works perfectly to notify you that a file was deleted/modified. But only after the fact. My question is, how can VB intercept a file operation I'm trying to create an application that protects files from being modified or deleted. Or at least display a dialog that a file is going to be modified/deleted. Similar to these applications... http://www.syssafety.com/product.html http://winpooch.free.fr/page/home.php lang=en&page=home nobugz : I had no idea it wasnt possible in vb2005. spotty: Thats an idea.

• Visual C# Reading the end of an XML file

  I have a program that cycles through an XML file and outputs to another file every 1000 records. Thyis works fine until the end of the XML file is reached, when it fails saying my 'root' tag is not closed - although it does for the previous files. It seems to be having issues with recognising the end of the XML file, so can someone please confirm how this is done Currently I have a while loop to do this, with a for loop inside to cycle through the records, ie: while (XmlReader.Read()) { ... for (int i = 1; i <= 100; i++) { while (reads in a node here) { does the work } } Close the XmlReader and XmlWriter } This works fine for the beginning, until the end of the file is reached; is my way of reading the XML file correct (I have also trie ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Games within a IE brower

  Not real sure if this is a new thread or not, but is it possible to create a game (actually more of a simulation) using the XNA game studio that would run in a browser window Does not necessarily have to actually run from a online web server, just be browser based. Thanks Currently, that is correct. The XNA Framework and WPF/E have nothing in them to facilitate them working well with each other. We are investigating a number of technologies and options right now to address the desire for a more "lightweight" download. --Stephen ...Show All

• SQL Server SQL Server 2000 Connects to Remote DB but not Local DB. Why?

  I am using MS SQL Server 2000, installed on my local machine. I use JCreator 3.50 as my development IDE for Java. I have Norton Internet Security, but it does not block port 1433, which I use for SQL Server. Windows Firewall is turned OFF. My hard drive died, and my backup died then as well (it had been fine 1 week before). I had to start from scratch. I installed Windows XP SE2, JDK version 5 (version 1.5.0_06, I had previously used 1.40) and SQL Server 2000 with SP 2 as well. When it didn't work, I uninstalled SQL Server 2000 and did a clean install of SQL Server 2000. Instead of the default instance, I gave the instance a specific name, so I would know what to put in the Java code. I can connect with a remote DB using the standard URL a ...Show All

• SQL Server Icons for Custom Tasks won't show up.

  All aspects of my custom task work well except for the icon! I have included the .ico in the assembly as an "Embedded Resource" and the icon has both 16X16 and 32X32 images. I have edited the IconResource property of the DtsTask attribute as follows: IconResource="MyNamespace.MyDLLName.MyIconName.ico", Where the output assembly is called "MyNamespace.MyDLLName.dll". Has anybody got this working before The Icon just never shows (I get the default blue square task icon). Thanks in advance. Someone changed it. I updated the IncrementTask sample to include an icon. 1 - Open project and select Add Existing Item, select any icon you have. 2 - Set Icon fil ...Show All

• Visual C# How to Delete a XML node on a particular line using C#!!

  I am trying to delete a particular text value along with its root in an XML file  on a given line number, using C#. But i do not know how to do it, Please can anyone suggest me a solution!! This is not possible using XML apis. Mark gave you work-around to do that but without using line number. Another workaound may be, - Use File apis, Open file and get the StreamReader object for that file. - StreamReader has "ReadLine" method which give you line from the file as string so till EOF read each line and add that into some variable - Then you can compare it with the text you have on that line and if its that line then dont add that to the variable - At the end, save that value in varible to ...Show All

• .NET Development Fetching URLs with axWebBrowser component

  Hello, I have been using HTTrack combined with ASP.NET and SQL Server to archive web sites for Washington State. HTTrack fails to get all of the references from a web page, many of which can be found by using the DOM interface. With that said, I am working on a C# application that will crawl a list of URLs (about 55,000) and extract any references to web documents missed by HTTrack. My C# application uses the Web Browser class (have tried the axWebBrowser class as well) and the IHTMLDocument2 interface. If I use my application and crawl about 5,000 URLs it works like a champ. However, once I pass the 5,000 mark I run into problems. Is there a limit on how many times the Web Browser control can have it's navigate function called Is there a ...Show All

• SQL Server Foreach Loop and distributed files

  Hi - I'm new to SSIS and am having problems figuring out how to do the following. I need to load data from flat files into SQLserver 2005 and have created the data flows ok, but my data files are *not* located in a single directory so I cannot use the foreach file enumerator option in the foreach loop container collection. Please correct me if I'm wrong My approach has been to execute a SQLcommand to get the filenames from another database table and to use the foreach ADO enumerator option and mapping the returned filenames to a project scoped variable (data type object since it is a rowset). My problem comes when I edit the properties of the connection manager to try to use that variable for the connectionstring property in the e ...Show All
