• .NET Development those extra columns in the Feature Table

  Just curious to know what are those extra columns in the Feature Tables of the .NET framework MSIs Short answer: the extra columns are not really used for anything in .NET Framework setup. Explanation: the extra columns in the Feature table are a side-effect of the internal MSI build system that is shared with the Visual Studio family of products. Visual Studio setup has a feature tree that allows advanced customization of feature install locations and run-from-source options. Those extra columns in the Feature table control the parameters of customization, and provide additional descriptive text. The build system outputs those extra columns for all products, but since .NET Framework setup doesn't have ...Show All

• SQL Server Dynamic XSD Schema Location For XML Source

  I want to be able to programmatically set the schema location for an XML source. I first thought it would be a simple task using expressions and variables but it doesn't appear to allow anything in the way of setting it at runtime. Is this possible Thanks Jamie... just wanted to chime in and say this was really helpful - I would have never thought of looking on the properties of the data flow. ...Show All

• SQL Server Find Counties in area

  We have the need to determine surrounding counties of a particular county. For example how can I determine, if I entered a zip code for Contra Costa and the property is also right on the line of alameda that Alameda is a neighboring county of Contra Costa Could it be determined by the longitude and latitude of the zip code in comparison with the counties Hello, Although I'm sure a geospacial co-ordinate system could be used to determine this, most people think it overkill and just use a proximity table :) tCounty (CountyID int, CountyName varchar) tCountyAdjoined(CountyID int FK to tCounty.CountyID, AdjoiningCountyID int FK to tCounty.CountyID) So if Contra Costa was near Ala ...Show All

• Visual C# question of what the difference is between...

  Yay! time for another newbie question. Is there a difference between these two lines string AString = new string(this); string AString = new string; If so, whats the difference Quilnux string type can be created using string constructor, but not in that way and for that purpose. You can see that string constructor has many overloads but none of them is empty constructor (without parameters) as your first example. String constructors are basicly used for creating string from array of characters or bytes, and for such conversion that is the easiest way. But you can't use the constructor with (this) because none of those constructors accept parameter of type reference type as in your case (some ...Show All

• Visual Basic Nead to pass arguments to an Event

  Hi there. I have created a class to handle network trafick. I strugeled a bit with this because the application got stuck when it was waiting on a client. I therfore dug a bit and found a class that would solve this for me. Problem with this class was that it was designed to handle a limited number of clients using an array of threads. I thought that I should rewrite this class to handle the threads in a list instead. I allso had the nead of an unique ID to handle the different connections. I found the datatype GUID and I think this is what I nead. So to my problem: I have a method in my class to handle network messages. It is prototyped like this: SUB HandleIncomingMessage(ByVal pClientID as GUID, ByVal pMessage as String) ok. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Probability

  Give the following below, how can I program the probability of those outcomes happening For instance given 10 calls to function GetRandomLetter(), I'd like "A" to return about 2 out of 10 times and "B" to return 4 out of 10 times. I'm trying to add random occurance to a game I'm working on but I'd like to set the probability certain events. A - 20% B - 40% C - 30% D - 10% I had that thought over the weekend. I just wasn't sure if there was a class or method in the framework that could handle such a thing for me. I'll give that a shot and see if that works. Thanks. ...Show All
