Hi sathya
I have 2 things to mention that may help.
1) Do you have this line included in your project "Post Build Event"
xcopy /s /y "$(ProjectDir)App_GlobalResources\*.resx" "$(SolutionDir)Web\App_GlobalResources\"
2) This line in your config file looks a bit strange.
controlSource="Cdtech/bandwidth control/BandWidthCal.ascx"
I would expect it to be something like:
controlSource="SlideShow/SlideShowModule.ascx"
or what ever you named the folder and module
