• .NET Development Memory leaking on one machine, but not another... HELP!!?

  HI I have a vb.net windows forms app (framework 1.1) It creates 4 user-controls on a window (which themselves contain a mixture of com and dotnet controls). It displays the user controls for a fixed amount of time, passing in image and video files to be displayed for fixed time-legths, then destroys them. Then it starts again. On my laptop, and 3 other machines I have at my disposal, the user-controls are disposed of properly, and memory is released, but on 2 machines, the memory is not released! It appears that Garbage collection is not working properly! This is running exactly the same binary .exe file on different machines, and all machines are running framework 1.1 sp1 on xp pro sp2. Can anyone give a reason why on one machine, the mem ...Show All

• Visual Studio 2008 (Pre-release) Focus Keyboard

  I am using Josh Smith's excellent DragCanvas to create a designer. I'd like to have keyboard events (OnPreviewKeyDown) so that when a user uses arrow keys it moves my design elements around on the screen. I give the selected element focus using: SelectElement(UIElement element) { this.selectedElement = element; if (element != null) { element.Focusable = true; Keyboard.Focus(element); // element.Focus(); yeilds the same result } } And it gives the element focus but shortly after (not sure exactly the Keyboard focus gets stolen! and it's no longer focusable. If I tab through the elements everything works the way I want--arrows moving element, etc... I've also noticed that if I call my SelectElement() method which uses the ...Show All

• Software Development for Windows Vista Initializing local services from App.Config

  I've seen plenty of examples on how to load core services (persistence, tracking, etc.) using entries in the App.Config. Is it also possible to load your own local services using App.Config entries If so, is there an example of how to do this somewhere Thanks. Bruce Bukovics Author of .NET 2.0 Interoperability Recipes http://www.apress.com/book/bookDisplay.html bID=10116 I was searching for more information on this very usefull feature.

• SQL Server SSIS XML Configuration updating at runtime

  How can I update a variable in the XML configuration file. Can I use the configuration object for it or do I need to use XML objects and do it just like any other XML file Another problem I have is, I know I can reference the same XML config file from 2 different packages. But every time I do that through the wizard, only the last package configurations are placed in the XML file. Any help is appreciated!   Hi Jamie, Right on the spot. That is exactly why I need this. I will pull records delta from a vendor and I need to persist the date somewhere. I've seen code with LoadPckage and app.LoadFromSQL etc. It seems not logical to load the same package while still in the package script ta ...Show All

• Visual C++ Urgent help required: Error 14001

  In Windows XP I ported a VC++ project previously built with ver 6.0 to 2005. I could run the application in my machine without any problems. But if I try to run the same in other machines, I get following error. This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem. I looked at various threads in MSDN related to this and I did following to fix the issue. 1. In the target machine which doesn't have VC++ 2005, I installed Sax binaries. 2. Tried to create VC+ deployment project and installed the same in the target machine. Both attempts are unsuccessful. Can some one give me hint please Thanks in advance ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Simple question. How to convert float to only 2 decimals?

  How do you convert float to only 2 decimals I want to display the elapsed time in seconds but the time is a float so it is displayed with 5 decimals and I only want 2. (24.47984 to 24.48) Cheers Alfons You can also put the numeric format in the format string, like so: testFont.DrawString(30, 30, "Pos: {0:F2}, {1:F2}" , thing.pos.X , thing.pos.Y ); Saves a little typing. See the MSDN docs on formatting for more about this. Cheers, Leaf. ...Show All

• Visual C# Calling Virtual Methods from Within Constructors

  [Reposted from .NET forum] I have an issue and I wonder if anyone has run into this. As I know, you cannot call virtual methods from within constructors safely, because the inherited class is not constructed at the time of base constructor invocation. However, I am creating a base class whose internal workings are sufficiently complex that I had to create a series of virtual functions that the inheritors can modify. These are called when a particular property is set in order to set up the connective tissue underneath. This is not a problem. The problem exists because I cannot use these same virtual calls on either deserialization constructors or in the default constructor to perform these same operations when the class is first in ...Show All

• Visual Studio Can it be done : Custom colors for bars in bar chart ?

  Is it possible to have different colors for bars in charts. I am wondering if there can be formula applied for each (x,y) values We are using Reporting services in local mode. If it cannot be done, it appears we have to purchase separate charting components. Thanks You can take a look at the following blog article which also includes a sample report: http://blogs.msdn.com/bwelcker/archive/2005/05/20/420349.aspx Within the next month or so there will also be a new MSDN article that specifically focuses on how to get more out of the built-in RS charts. -- Robert ...Show All

• SQL Server Confusion over @@ROWCOUNT test

  I have a pair of services. One is an initiator of a conversation, another is a target. I have a pair of message types, one sent by the initiator one sent by the target. I have a pair of queues corresponding to the above services. Both queues have activation stored procedures associate with them. The intiiator sends its mesage to the queue that the target service is defined on. The activation procedure successfully retrieves the message, does some work and then sends a reply message on the same conversation to the initiating service. At this point behavior seems to become strange. Some of the time the send from the target service produces the "zero length message" error and indeed at times the message body is em ...Show All

• Visual Studio Sandcastle assembly collection to multiple .CHMs?

  I want to document the APIs stored in multiple .DLLs so that each .DLL is documented in a separate .CHM file. There are basically primary and secondary .DLLs, and the secondary ones might not be installed. If they are, though, they'll reference classes defined in the primary .DLLs. I can make a single .CHM with cross-references among the classes, but is there a way to use Sandcastle to generate separate .CHMs and still have the appropriate links between them ...Show All
