• Windows Live Developer Forums Packet rate

  Just a small question about the packet rate, does the 120 packets a minute apply to incoming and outgoing, or is it applied to outgoing packages only. Would make a big difference because if it applies to the total ammount of packages it means you can only send and receive a packet per second if you are using real-time package data. -joost As far as I know there isn't a real limit on the size. At least it's not meantioned anywhere (as you probably already noticed) and I have never experienced it. The 120 / minute limit is easy to test, because with a provisioned app, Messenger will just cut off your connection after packet 120 untill the minute is over... So, I'd say give it a try, and see how it be ...Show All

• .NET Development Way around Application scope connections?

  Is there a clean way to get around designer limitation where connection settings can only be defined for the application scope Don't worry why I need to do this, suffice it to say it is required to allow the user to change database connections and have the last connection used be saved. Also, is there a MS recommended way of having all Dataset instances retrieve their connection from a single source Thanks The only way I could find to do this is to reset the connection string after the dataset and dataAdapter is created. It's not pretty, but there's no other way I could find around it without breaking the designer. ...Show All

• Visual C++ How do I spawn a new process that inherits the shell environment ?

  Hi, I was wondering whether it is possible for a process to spawn a NEW process , but one that would not inherit the environment of the creating process but rather inherit the environment from the shell. For example , I tried to create a server/client application where the server creates a new client upon request (using ShellExecute ). The client checks the value of a certain environment variable. I'm changing the value of this environment variable between requests but the clients keeps showing the old value, the one that was valid when the server started. Is it possible to achieve what I have described Thanks. I think instead of ShellExecute you should consider other functions which ...Show All

• Visual Studio Team System MsTest / VSTestHost Memory problem

  Hi, Sorry if this is isn't the right place to post this. I am running Visual Studio 2005 Team Suite Version 8.0.50727.42 (RTM.050727-4200) I use the MSTest a lot and find the VSTestHost is eating up a lot of memory, which isn't freed up even after the tests have finished running. I have over 1000 tests and after several test runs the tests will start aborting complaining of insufficient memory, I am required to restart the machine in order to free up the memory fully. The memory usage will ofter go beyond 1.5gig. I have tried this on two different machines and both exibit the same problem. The tests we run interact with MSSQL, creating, retrieving, updating and deleting from the database. It may be the case that it is an issue with the t ...Show All

• Visual C# Drawing a semi-transparent image using GDI+

  Hi, I am trying to find out how to change the transparency when drawing a image to the screen using GDI+. The effect I am trying to produce is a image fading in and out. bratheo, this is what I have figured out recently (not sure if it is exactly what you want) to draw something, say a semitransparent rectangle (g is your graphics object) g.FillRectangle( new SolidBrush( A, Color.Blue), ......); A neesd to be a value between 0 and 255. 255 means totally opaque and I think 0 is totally transparent. Anywhere in between will give you different transparency levels. Hope this helps Fradam ...Show All

• Windows Forms BindingList.Add behaviour (Extremley slow!)

  I am trying to improve a bindable class that supports filtering. I use a class I found on a blog somewhere. After some fidling I get it to work, and I have replaced the Filter functionality with my own RegEx filter that works nicely. My problem, however, is that the BindingList.Add method is so extremly slow! The functionality is like this: I have a textbox where the user inputs his filter. On the Change event I update the BindingSource.Filter property, and run my own filtering code. When the user removes his filter, the original values should be shown again. This is when the problem arises. I have to clear the bound collection, and copy the values from the original collection back. This should be extremely fast, since it is an in-memory l ...Show All

• SQL Server Architectural Design Question ?

  We currently have a number of SSAS 2000 physical cubes and a single KPI virtual cube that our finance department reports from. A colleague is prototyping a new approach in SSAS 2005 and I’m looking for some feedback. Please see http://www.dailyware.com/SSAS2005Design.jpg for a high level overview. The lines in red illustrate custom .Net applications that push aggregated data from cubes to some other reporting source (SQL tables, XML ) that our finance department will report from. Thought that come to my mind include: many points of failure, significant custom development required, none-mainstream, high maintenance cost….
