Entity Framework SQL Parameters not getting supplied -

-

this thread gives number of ways provide parameter stored procedure.

none of them working me.

this works:

this.payrollcontext.database.sqlquery<csrrateentity>("ord_getcsrrate @csr_num = '4745', @ord_pay_period_id = 784").tolist();

this not:

return this.payrollcontext.database.sqlquery<csrrateentity>("exec ord_getcsrrate @csr_num, @ord_pay_period_id",             new sqlparameter("csr_num", "4745"),             new sqlparameter("ord_pay_period_id", 784)             ).tolist();

the error message parameter not supplied.

have tried variations can think of , still same error message.

this using code first, no import required. sp found, missing parameters.

did import stored procedure edmx?

in implementation have stored procedure creates parameters this:

    var inputidparameter = inputid.hasvalue ?         new objectparameter("inputid", inputid) :         new objectparameter("inputid", typeof(int));

the result of stored procedure function given this

return ((iobjectcontextadapter)this).objectcontext.executefunction<t>("[sp_name]",  inputidparameter);

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
