• Visual Studio Express Editions How to limit decimal places after a double?

  Hi, everyone E.g. double op, Q = 0.112233445566778899, H = 100.0, k = 20000.0; op = Q * H * k; Can the decimal places of "op" be limited to ..... let say 6 decimal places OMG. Tried your code and it didn't work. Thanks for the tip. Maybe because its a console application This works: double d1 = 0.10999300000001; d1 = Math .Round(d1, 6); Console .WriteLine( "{0:N20} rounds to {0}" , d1); Anyway, my line of code above works fine in my application. I would not need to assign d2 to a rounded off d1. I only need to control the decimal place after my calculation. Furthermore, I could even store it into my database. ...Show All

• SQL Server Upgrade from SQL 2000 to SQL 2005 - Any known issues?

  Hello, First off, thanks to all for taking the time to read and respond to this question of mine. Greatly appreciated. Let me explain my current scenario followed with the question. We currently have our VB application written and working at various client sites on SQL 2000. We did received a number of request on upgrading to SQL 2005. We did some preliminary testing in-house on SQL 2005 (backed up the 2000 database and restored on 2005 which worked just great). It is also my hope that technically, everything should work just fine since 2005 is backward compatible to 2000. Is anybody aware of any issues with taking a 2000 database and getting it to work on SQL 2005 without any mods Thanks. The ...Show All

• SQL Server Long running stored proc in CLR

  How does one prevent a long running procedure form crapping out in CLR I am trying to do a pull from a distant data source and it works, except I have to break down my stored procedure call into several smaller calls. I would like to do everything in one shot, but I get the thread abort exception when I try to get a lot of data. Any ideas Thanks. It's not the time that's causing the issue, but more likely the memory utilization.  There is a hard cap on the amount of memory you can use, after which you'll receive a ThreadAbortException if some of the objects can't be garbage collected.  Did your ThreadAbortException include a message along the lines of:   ...Show All
