thanks

I found the problem. In "Business Layer Generator" on "Data Access Layer Options" wizard Page default option is "Use Dynamic SQL Statements" by default selected, but in "ABusinessObject.cs" DefaultCommandType is 'StoreProcedure' so after change to 'Text' now its working fine. Basically I am VFP (codebook 6.2 modified, as well ) user so bet newbe in .Net. so now i m in learning state.
again thank to all
