• Visual Studio Reportviewer/Sql Server 2005 Reporting Services Parameter passing problems - Help!

  I'm trying to pass two parms to a (remote) report using the reportviewer control (from a windows form or webform) but when the report is displayed it ignores what i've passed and just displays the report with the parm drop-downs. If I use an incorrect parameter name, it throws an exception so it seems to recognise the parm names... Any suggestions gratefully received! Parameter definition in the RDL:   <ReportParameters>     <ReportParameter Name="FlightRouteDestinationCountry">       <DataType>String</DataType>       <Pro ...Show All

• Visual C# Timers

  Hi, I need a timer so that it keep going and doesn't stop. How do I do that Should I set the interval of the timer to inifinity Also how can I make the timer return the number of seconds counted so far Thanks for the help, Bruce A timer doesn't stop until you call Timer.Stop(). The interval is a mechanism for triggering timed events, but it won't actually stop the timer. To keep track of how long has elapsed, set the interval to a reasonable division of how long you expect the timer to run for, and keep the multiple stored. Then simply perform the maths on the multiple, and the interval - an ...Show All

• Smart Device Development #Define Replacement (C++) in C#/NETCF

  I'm used to the world of C++/C where i had access to #define. This was great, as I could define a keyword during development, and this keyword would be overwritten with an actual value at compile time. I notice c# doesn't have this (for obvious reasons), however, what is the recommended replacement I understand that I can use a constant (within a single file), however I'm working in multiple files. Should I use a constant within a singleton so each of the seperate classes can be set to the same value... There has to be a better way Thanks! ...Show All
