• Visual C# Hi, how do I enforce that the Denominater of a Fraction struct will not be initilized to o on creation?

  since I can't define a parameterless Ctor, the compiler defines one automatically so the denominator will be initialized to 0 and it's undesirable. Hi, You could then add a getter initialization for your denominator variable (dont set the modifier of your denominator variable to public): public struct Fraction {    private int denominator;    public int Denominator    {       get       {          if (denominator==0)          {       & ...Show All

• SQL Server Need urgent help

  Hi I have a strange situation. We have a middle teir application (j2ee appserver) that uses connection pooling. The client was working fine when all of a sudden it hangs. I have checked the sp_lock and sp_who2 and there has been no locking/blocking whatsover. This problem stays until we restart the app server. Is there any way that I can further dig into this problem and find it out if it is the db that is causing the issue. I used sql profiler and I could see some log entries made into the database while client is hanging after that. Also sp_who2 lists the spid for the middle tier connection. It does not however show any loc ...Show All

• SQL Server geometric datatypes

  Hi, Is there any equivalent in SQL Server for Oracle's datatype 'SDO_GEOMETRY' Smitha No, there is no built-in data type for storing spatial data. In SQL Server 2005, you can create your own CLR user-defined type and use it. In addition, there are other ways to do deal with spatial data. See the links below for more details. They contain whitepaper, sample from SQL Server 2005 CD etc.   http://msdn.microsoft.com/sql/learning/prog/clr/default.aspx http://msdn.microsoft.com/sql/learning/prog/clr/default.aspx pull=/library/en-us/dnsql90/html/tblvalfuncsql.asp http://msdn2.microsoft.com/en-us/library/ms345264 ...Show All

• Visual Basic Program help

  Ok here's the thing.  I need to write a program that will compare multiple lists of numbers.  Each list would contain 6 numbers 1-39.  You would type in each list in a separate text box, and then each list would be compared with each of the other lists one at a time.  The program would compare based on two factors: 1. how many numbers each list has in common, and 2. the positions (if it were the first number, second number, etc.) of each of the common numbers.  The program would then rate each pair on a scale from 1-10. I know basic Visual Basic but this is way over my head.  Could someone please help ...Show All
