• .NET Development GCHandle.Free explanation

  Does GCHandle.Free dispose of the object being freed if the object implements the IDisposable interface Peter Ritchie wrote: No. A GCHandle is a garbage collector handle, not an object reference. Freeing a GCHandle does not directly free the memory occupied by the object for which it a handle for. I wasn't asking whether it freed the memory occupied by the object for which it had a handle but rather whether it called IDisposable.Dispose on that object. Obviously calling the finalizer and freeing the memory is done by the GC. However I take it from your answer that it wisely does not call IDisposable.Dispose, especially since other references still might exist for the object, and I thank you for ...Show All

• Windows Forms Windows installer launch condition

  Hi Guys, I am trying to create a setup and deployment project in VS 2005 for a windows form project. A couple of dependencies for my application are - 1) .NET framework 2) ActiveState Perl 5.8.8 I have been able to successfully add the .NET 2.0 framework check to the launch condition. I've also added the Active Perl check but its not working right. I mean, I get a "perl not found" error even on systems where the perl is installed. How should I correct this behavior Its probably something in the Condition check that I'm messing up. Here are the properties I have for perl launch check - (Name) ActiveState Perl Condition Installed InstalllUrl <url> Message Perl could not be found. Please install ...Show All

• SQL Server sql connection

  hello, Is it possible to use TELNET(from the client in LAN A) and access database instance at(sql Server at LAN B) . I meann to say is, can we use TElnet over the internet to access the instance. can anybody helps me Thanks in advance YOu can open a port to SQL Server via telnet, it questionable what you can do with telnet on the instance. You can also use any query tool to access the appropiate port on the SQL Server. If the Server is behind a firewall you will have to do a port fowarding, opening the firewall and redirecting the request to the sQl Server. HTH, Jens K.

• Software Development for Windows Vista Add/Remove Programs in Windows Vista

  Add/Remove Programs in Windows Vista So you say you can't find the Add/Remove programs function in Windows Vista Well, in Windows XP Add/Remove Programs is in Control Panel under an icon of the same name. But in Windows Vista it has been changed to "Programs and Features". To locate the Program and Features function: 1. Click Start and choose Control Panel, 2. In Control Panel double click on the "Programs and Features" icon. 3. Here you can find all the programs and items which are installed in Windows Vista. 4. To remove any of them click once on the program you want to uninstall and then click on Uninstall/Change and follow the prompts. Now wasn't that easy! Yes that was very easy.

• Visual Basic Question about BackgroundWorker

  I have a small program that will allow a user to select a handful of files (installers) and it will install them automatically. I have it setup now like so: Dim Proc As New System.Diagnostics.Process Proc = Process.Start(Files(Int), "/VERYSILENT" ) Proc.WaitForExit() I have that inside a loop that goes through each file that was selected. This method causes a delay for my program as it freezes until the install has finished. I was thinking about using a BackgroundWorker to do the installing instead. The thing is, I cannot figure out how to only install one file at a time with the background worker. If the user chooses 20 files I don't want all 20 to start at once. I tried adding the above code in a DoWork event for m ...Show All

• Windows Forms Problem with Automatic Text Wrapping and MeasureString

  I've been trying to create my own Chart control, and I've been having a problem printing the labels against the x-axis. I divide the x-axis into the number of elements being displayed on the chart. I then measure the width of the text of the labels, to make sure they fit, using MeasureString and passing it a RectangleF to work out if all the characters fit in. My problem is that when I call MeasureString, the charactersFitted parameter comes back with weird information. Say I meaure the string "30th Birthday Celebrations", and "30th" and "Birthday Celebrations" are printed on 2 lines (the second only saying "Birthday Cel". The MeasureString returns 14 characters fitted and 2 lines I can't ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. My 1-week XNA evaluation

  Hi! I've been evaluating XNA Game Studio Express for about a week now. Writing this little report to get some thoughts and ideas out of my system. If you just want to download the game I made, here it is: http://www.artplant.no/Johan/XNATest.rar Everything is original and copyright (c) Artplant, except for the sound assets and the sound code, which was ripped from the SpaceWar sample in XNA. Someone please give me a heads-up if that's illegal for some reason, and I'll take it out. You'll need a shader model 2.0 GPU to run the game. Also, you'll need a 360 gamepad or similar. (Don't know if XNA is compatible with other pads yet.) Both of the thumb sticks fire cannons independently when pushed. Enough of that, here's a quic ...Show All
