c# - convert type 'object' to 'System.Data.SqlClient.SqlCommand Error -


cannot implicitly convert type 'object' 'system.data.sqlclient.sqlcommand'. explicit conversion exists (are missing cast?)

i got error while creating usercontrol

it in code.

  protected void gvdetails_rowupdating(object sender, gridviewupdateeventargs e) { int slno = convert.toint32(gvdetails.datakeys[e.rowindex].value.tostring()); var productnum = gvdetails.datakeys[e.rowindex].values["productnumber"].tostring(); textbox txtshortdesc = (textbox)gvdetails.rows[e.rowindex].findcontrol("shortdesc"); sqlcommand cmd= sqlhelper.executescalar(globalsettings.dbdsn, commandtype.text,"update sydshortdesc set shortdesc='"+ txtshortdesc.text+ " ' productnumber='"+ productnum +"'  "); cmd.executenonquery(); lblresult.forecolor = color.green; lblresult.text = username + " details updated successfully"; gvdetails.editindex = -1; bindemployeedetails(); }

well presumably sqlhelper.executescalar method declared return object, not sqlcommand. indeed, wouldn't expect return sqlcommand - i'd expect return results of executing given query. suspect don't want call executescalar in first place.

as very important aside, current code vulnerable sql injection attacks - should use parameterized sql instead of embedding values directly sql.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
