• Visual Studio 2008 (Pre-release) TCP Streaming - Performance Issue (RTM)

  We have been testing a simple scenario with different WCF bindings to see the performance benefits. The scenario is that client makes a call to a web service with numer of customer objects to return in an array. The service simply creates as many objects as required by the client and send them to client. The customer object is a simple class with 2 public properties, firstname and last name. Each of these names is set to a distinct value in each of the customer objects before returning to client. We set maximum times for send and receive timeouts. We also made sure that there are no message size, maximum depth related problems etc. We used a System.Diagnostics.StopWatch class to measure the time from the time client initiates the reques ...Show All

• Visual C# Switch statement

  Hi, all: [I guess this could be considered a rant, but I'm still curious if anyone shares my opinion on this] I am still wondering why the switch statement is not more flexible. For example, I feel that a switch statement using objects makes sense. I'll give a more visual example for ease of understanding more than anything else, so picture this: I have three buttons on my form, button1, button2, button3. I set the click event to the same event handler, button_ButtonClick. Inside the button_ButtonClick method I want to check the sender to see which button was clicked, so I do this: switch (sender) // or even (sender as Button) { case button1: // do something here break ; case button2: // do somethi ...Show All

• SQL Server Sql Delete Question

  I don't know if this is where I should post or not. I am trying to figure out how to get this select statement which generates all of the records I need to delete. Here is the select statement.

  Hi all, I have a customer with an RS installation in a DMZ, using ADAM for its authentication.

• Architecture Solution Design?

  I was wondering if anybody could give me a few pointers on designing a large solution. We have a rather large application written in a legacy codebase that we are rewritting from the ground-up in C# 2.0. One of the problems I constantly face is the fact that I would like to break things up into separate projects to group common things together but then I always face the problem of "circular references". Can some of you folks who are developing large applications give me some insignt in how you structure your solution(s) I have thought about having separate solutions, but that seems to defeat the purpose of having multiple projects in the same solution! Here's one example of a problem that I face. I want to segregate al ...Show All

• Visual Studio Express Editions Splash screen and startup?

  I have a splash screen which I would like to have shown as the first thing when a user runs my program. After 20 seconds it should close and reveal the main form. ATM I have the following: I have the splash screen set as the startup form. A timer event on the splash screen form with the following: Me.Close() main.Show() When I run this the splash screen loads sticks around till the end of the timer, then the main form briefly flickers into view before it disappears again and the program seems to end. Does anyone why this isn't working Because by default the settings for a windows app is to end when the startup form is closed...you can prevent this behavior by setting the "Shutdown Mode" to &quo ...Show All

• SQL Server SSAS: SessionTrace during XMLA execution?

  Hi all! I wrote a command line tool that processes a SSAS cube/dimension. At the moment the tool starts processing similar to: using Microsoft.AnalysisServices; olapsrv = new Server(); olapsrv.Connect(@"SERVER/DATABASE"); Database mydb = olapsrv.Databases["NAME"]; Cube mycube = mydb.Cubes.FindByName("CUBENAME"); mycube.Process(ProcessType.ProcessFull); it is possible to trace the server output with: olapsrv.SessionTrace.OnEvent += new TraceEventHandler(DefaultTrace_OnEvent); olapsrv.SessionTrace.Stopped += new TraceStoppedEventHandler(DefaultTrace_Stopped); olapsrv.SessionTrace.Start(); the two functions can write the "feedback" to a file or to the command line...

• Visual Studio Express Editions Component Question

  Hi again, I've been trying to build a component as Express doesnt come with a component template, does anyone know what code I need to insert in order for it to work correctly I am sure its not as simple as merely putting 'Inherits Component' under the class declaration, I'm pretty sure you have to some stuff with the 'New' and there's also a 'Site' property that needs sorting out. Like I said, I'm new to this, but if anyone could post the generated code for a new component, that would be great. Thanks again. Okay, I found out where the component name is situated. If you inherit from Component, you can access the name property of the component from Mybase.Site.Name That brings me to another question, assuming you cr ...Show All

• Visual Basic Public Array

  I've read in the forms about making a public variable in a form accessible to another form in the same project, and have been able to do so with a single variable. Is there a way to share a complete array (to be specific e.g. String Array(i,j,k,) where i,j,k are all integers) in a project between forms - i.e. From Form 1 to be used in Form 2. I have coinsidered referrencing every variable in the Array by a loop subroutine, but is there a better way Thanks CRV If I understand correctly, you wish to share an array publically to other forms/classes if so then yes, its done in the same way, only difference being is the type of property, the array type name. Example: public property MyArray() as String() 'ar ...Show All
