• Software Development for Windows Vista Help on Vista-RC2 with sector writting.

  Hi all, as this is my first post I hope Im posting in the right Place. I recently used the new Ms OS Vista-RC2 and encountered a problem with sector writing for files. Opening the physical volume of the drive (ex. "\\.\C:") and pointing to the sector that I want to alter by using SetFilePointer, works fine when I read the bytes from a certain sector point. But if I try to write to that sector I always get access denied (Error No 5). If on the other hand I open the file and write to it, works fine. Also the method I used worked ok in XP, but it seems in Vista-RC2 it fails with "Access Denied" Error. I have to say as well that Im executing the code as administrator so I believe I have all the priveleges ...Show All

• Visual C# a question regarding c# current situation

  I am a newbie and was wondering, where does C# currently stands in I thought its popularity was on the rise specially in games, but I just saw the article in the front page saying that it has fallen down one slot in the popularity rankings compared to last year. do you guys think that it will be more popular in the future Also, as someone who is just entering this world, is there anything that you can do with c++ that you cant do with c# and vice versa I would like to know a little comparison. Thanks in advanced !! C# is always strong and will be. C# is an industry standard language and majority of employers on the MS Development platform look for C# developers. It's worth learning of course. C# is a "higher&quo ...Show All

• Visual Studio 2008 (Pre-release) How to exit a WPF application

  Is there a way to force a WPF application to exit,.. something like application.Exit() in windows forms If not, how can I, for example force an application to exit on a button click Thanks in advance, Marko Vuksanovic. When you call Window.ShowDialog(), WPF will actually pump a new nested message loop, the problem is that during the initialization of Window1, there is some layout taking place, the problem here is that WPF will disable nested message loop when doing layout, that's why your application crashes when you call popUp.ShowDialog(), actually Nick Krammer has a blog article dedicated to nested message loop. Nested message loops are evil (if you're a platform) Sheva ...Show All

• SharePoint Products and Technologies sometimes i can break through code in vs2005 to debug a site

  I build my debug version, install it in GAC, then I reset iisreset .When i place a breakpoint I get the message: breakpoint will not currently be hit. no symbols have been loaded for this document Have u had this before. MKeeper, thanks for your input. It makes sense, but it doesn't clear it up ... at least not yet. Maybe I'm doing something wrong, but like the original author, even when it's not a site provisioning assembly, the breakpoints don't work unless I do as I explained. Then they do. In other words, if I install the debug version of an assembly with breakpoints into the GAC without doing anything else, the breakpoints don't work, even after all relevant assemblies have been loaded AND run. The assemblies in question ...Show All

• SQL Server Virtual Labs - No Connection message

  A couple of us are trying to use the SQL Server 2005 Virtual labs at http://msdn.microsoft.com/sql/  .  We complete all the prelim steps successfully but when we click on "Start the Lab" we get a blank page with "No Connection" in the middle.  The clock ticks and the system thinks we are doing the lab.  How can we get a connection   or is the server down   or are there no available resources left Great news!! The next ActiveX control is coming out tonight. Please try Virtual Lab again and see if it fixes your problem. NOTE: When you login, it will seem as if you don't have the activeX control installed and will prompt you for a new installation. This is an expected proced ...Show All

• .NET Development Threads and database connections

  I have an application that kicks off a long process on the database server with a separate thread and then forwards the user to another page which monitors the progress of this process by reading a table that is being updated by the long process. On my development machine it works fine but when I try to deploy the app to a server the long process is blocked from database access. Apparently when the new thread is created it either does not get or loses its credentials. On my dev machine it is not a problem because it simply reverts back to my credentials but on the server it reverts back to the default IIS user. How can I work around this ...Show All

• .NET Development How can I detect available SQL server instances in the neighboring network?

  I'll include this in my installation program so that it's easier for users. Any idea Thanks Hello, You actually need to call EnumAvailableSQLServers not just once, but multiple times. I actually saw this recommended by microsoft, however I can't find the link, sorry. The reason for this is that some instances out there may timeout before they're able to respond to the broadcast on UDP 1434. So, if you create a list/array etc and store the results of EnumAvailableSQLServers, then call EnumAvailableSQLServers again and append any newly-found instances from the second call - you'll find that there will be more instances discovered. You can see this in action when you execute osql -L from the command-line (which again j ...Show All

• Visual Studio Tools for Office How do I get access to ribbon controls at runtime (C++)

  I need to be able to programmatically disable and enable certain ribbon controls (ex: Save, Print) at runtime in an C++ (ATL) addin. I've figured out how to disable them with the ribbon XML at application startup but I need to be able to turn them on and off in response to runtime actions / events. Can anyone point me to the correct COM interface(s) to manipulate these objects at runtime. I can't believe it's this hard to find but I've been searching for several days now. Thanks in advance.
