• SQL Server What's wrong with SQL Server E-Leanring?

  Hi, all, Thank you very much for your kind attention. Think I should put this post here for help as I cant find any other forums appropriate for this problem tho. Thanks a lot for that. My question is: what is wrong with the E-Learning for the Microsoft online E-learning courses (the one I am looking at is new features of Microsoft SQL Server 2005 Analysis Services) As I have tried so many times to launch the E-learning tools, but it always just showed me the content while not any tool to start the learning. I have tried ages for that. Could anyone here give me any advices and guidance for that (I actually just used it yesterday, it was fine, but not now I have tried both 'launch e-learning' and 'view e-learning details' , bo ...Show All

• Visual C# Check file signature?

  Is it possible to compare a file's signature to a string Thank you. Evan Mulawski Hi Evan. I'm answering to your post asuming a couple of this... since I'm still not sure of what you want. Most files start with a header. For example, a bmp starts with the BITMAPFILEHEADER. Within this header usually , the first bites are a signature . For example, the BITMAPFILEHEADER start with BM. Anyhow, I assume you will not know what your file contains... so you can't assume that it starts with text. Therefor the answer to your question is " no ". What you can do is convert the string to binary and compare it with the file's first bytes. This is: public bool FileStartsWith ( string signature, string file ...Show All

• Visual C# Method Parameter Naming Style

  Sometimes I have a method that initializes a class by passing in a few values. In this situation, I generally want to set the value of a private member from the parameter value passed in. (In other words, I don't want to "Set" the property and trigger code in the Set method.) So my code would look like this (** this obviously won't work.. hence, my question... *) public class MyClass{ int x; int y; public void Init( int x, int y ) { x = x; y = y; } I have read many suggestions on naming styles, but so far I haven't seen an example of the "right" way to handle this. I've played with different prefixes and other tricks to rename the method parameter, and of course any of them work , but I ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. z-buffer sorting?

  In experimenting with drawing multiple objects on the screen, I've found an interesting situation. I the picture below, the larger craft is closer to the camera, the smaller craft away from the camera. But if you look at it, the larger craft cuts into the shape of the smaller one, even though it is far enough away not to do that. In my drawing code, I know I'm drawing my smaller craft after the first, so there is clearly some kind of z-buffer problem. What I don't know is how to decide which object to draw first reglardless of camera positioning, or even if XNA has any help with that. Any ideas http://www.spellflight.com/images/zbuffer.PNG It's simple, just set these two render states before you draw y ...Show All

• Software Development for Windows Vista Step-by-step UAC Guide

  Can someone tell me, step by step, on how to add UAC elevation to apps in Vista I'm looking for elevation prompts to let the application carry out some Admin-specific tasks sometimes. UAC dcumentation is really, really poor and non-existent and existing Microsoft sites just goes on about how ingenious UAC is but never really goes into much details on HOW TO ADD it to applications.

• Windows Forms Does anyone got this unable to copy setup.exe error?

  I get the following error once it a while. I reboot the box and it goes away. It looks like something making setup.exe hot. Failed to copy file "local setup.exe" to "server setup.exe". Unable to add 'setup.exe' to the web. The file 'setup.exe' already exists in this web. Thanks. This is really making me nervous. For some reason when I try to publish I keep on getting this error. I changed the version numbers and nothing happened. I asked all the users to reboot(in real world that would be disasterous) and still getting the problem. Only thing pending is to go to the box and see who is holding the file and release file manually. But my concern is why would this happen and in enterprise situation we ...Show All

How will I do this Will this require math for subtracting the differences between two colors, divide by 100, and subtract the color by number that I've divided by 100 For example, in pixel X:0 and Y:0 of day.png and night.png, day.png has a color of R:64, G:224, and B:255. Night.png has a color of R:0, G:24, and B:32. So here's how I do it: day.R - night.R = 64 - 0 = 64 day.G - night.G = 224 - 24 = 200 day.B - night.B ...Show All

• Visual Studio 2008 (Pre-release) if client use more than one service

  Dear All, Please explain me, how client can access more than one service I generate 2 proxy-files over "svcutil" tool but these files cannot be compiled together in one project because it has doubled types in this proxies. If anybody have a sample - it would be great! There are a few things to consider here: Two services with distinct types Two services that share types The default behavior of "Add Service Reference" calls svcutil.exe to generate your proxy and related types. It wraps the types and service contract and proxy within a single CLR namespace, that you specify, but it defaults to "lo ...Show All
