• .NET Development Reading file size and then store the name, date and size in database

  I'm trying to make a program that basically say that every morning run this directory and scan through all the files. Then record the name, size and the date and then compare with the one that already existed in the database. If everything is match then pop up message say GOOD. If something has been changed then pop up a message say NOT GOOD. But aslo if i know that there was an update on the file so the date has been changed, that program should also have an update function to update the database. For instance File1 800kb 7/18/2006 File 2 1mb 7/17/2006 because this is the first time i run this program so i have to insert this into the data base. so after inserting, the database will have a list of file 2 and 1 with ...Show All

• Visual C# Visual Studio is acting weird

  I am having some trouble with the Visual Studio IDE. I have a solution sol.sln and I have some projects under it. All the project files and solution file are under source control. I have added the projects to source control using Visual Studio itself, so I couldn't have gone wrong there. When I open the solution and build it, it tries to save every project that is in the solution. Since the .csproj files are under source control, it says 'Access denied' when it tries to save. I have been using this solution from more than 2 months now and this weird behavior has started recently. Another behavior is that when I open the solution and try to close it (without any edits/changes) it asks me if I want to save the following files and the list o ...Show All

• .NET Development Efficiently handling xml fragments in a file

  I'm looking good way of reading a sequence of serialized XML fragments (subtrees) one at a time from a file containing a sequence of serialised XML nodes. I will be performing XPath queries on each of the subtrees. I have a program that reads XML subtrees (fragments) from a log file as it is being written. Currently, it uses a File System Watcher to be notified that data has been added to a file, reads it through a FileStream, splits events using Regular Expressions and runs each event into an XmlTextReader. At this point it uses an XPathDocument, Xpath and an XMLNavigator to select information for display. I was hoping to improve the program by eliminating the use of Regular Expressions to improve efficiency and the accuracy of spli ...Show All

• SQL Server Processing of cube created via DSO in AS 2005 fails

  We are testing an application originaly written for AS 2000 with AS 2005. This application uses DSO from VB to create and process cubes. I have gotten over the major hurdles of getting DSO to work with AS 2005. However, upon creating of the cubes, I get errors processing it (even from Management Studio). Here's the code (abridged to remove error handling) that we use to create a cube: Dim dsoCube As DSO.MDStore Set dsoCube = m_dsoDatabase.MDStores.AddNew(cubeName) ' set the cube's description dsoCube.Description = sCubeDesc ' set the cube's datasource dsoCube.DataSources.Add m_dsoDatabase.DataSources(mvarDBName) Dim dboStr As String dboStr = sLQuote & "dbo" & sRQuote & "." ...Show All
