asp.net - Show two columns with the same name in Gridview -

-

i have gridview uses join. 2 of columns, different tables, have same name:

<asp:gridview id="viewthemetypeassociationsgridview" runat="server" autogeneratecolumns="false"      backcolor="#deba84" bordercolor="#deba84" borderstyle="none" borderwidth="1px"      datakeynames="pk_user" cellpadding="3" cellspacing="2" datasourceid="sqldatasource6"      onrowdatabound="viewthemetypeassociationsgridview_onrowdatabound">      <columns>            <asp:boundfield datafield="name" headertext="name" sortexpression="name" />            <asp:boundfield datafield="name" headertext="organization team" sortexpression="name" />      </columns>      </asp:gridview>      <asp:sqldatasource id="sqldatasource6" runat="server" connectionstring="<%$ connectionstrings:applicationservices %>"                                             selectcommand="                                             select [user].[pk_user]                                                 ,[user].[name]                                                 ,[organizationalteam].[name]                                             [user]                                             left join [organizationalteam] on [organizationalteam].[pk_organizationalteam] = [user].[organizationalteamid]                                             coalesce(cast([organizationalteam].[internalexternal] varchar(255)), 'null') @internalexternalparam                                             group [user].[name]                                                 ,[organizationalteam].[name]                                                 ,[user].[pk_user]                                             ">     <selectparameters>           <asp:querystringparameter name="internalexternalparam" defaultvalue="%" type="string" />     </selectparameters>

i having trouble displaying it. way assume done follows:

<asp:boundfield datafield="[organizationalteam].[name]" headertext=" team name" sortexpression="[organizationalteam].[name]" /> <asp:boundfield datafield="[user].[name]" headertext="team" sortexpression="[user].[name]" />

this causing following error:

user neither datacolumn nor datarelation table defaultview.

how present 2 columns different tables same name.

the problem column name both, suggestion use alias on them distinguish between data each table:

select [user].[pk_user]     ,[user].[name] username     ,[organizationalteam].[name] organizationalteamname [user] left join [organizationalteam] on [organizationalteam].[pk_organizationalteam] = [user].[organizationalteamid] coalesce(cast([organizationalteam].[internalexternal] varchar(255)), 'null') @internalexternalparam group [user].[name]     ,[organizationalteam].[name]

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
