c# - Getting SCOPE_IDENTITY from SQL Server on Insert -

-

i guess late , i'm tired see i'm doing wrong. here i'm trying:

int imageid = imagedal.addimage(new sqlparameter[]         {             new sqlparameter("@image_id",          sqldbtype.int, int32.maxvalue, parameterdirection.output,         true, 0, 0,"image_id", datarowversion.current,dbnull.value),          new sqlparameter("@image",          sqldbtype.image, 11, parameterdirection.input,         true, 0, 0,"image", datarowversion.current,image)         });  public int addimage(sqlparameter[] spparams) {     sqlhelper.executenonquery(basedal.connectionstringimages, insert_image_sql, spparams);     return convert.toint32(spparams[0].value); }

stored procedure:

[dbo].[sp_insert_image]     -- add parameters stored procedure here     @image_id int out,     @image image begin     insert images     (image)     values     (@image)     select @image_id = scope_identity(); end go

i dbnull spparams[0].value. i've tried setting value of @image_id constant in stored procedure yet didn't change problem isn't stored procedure (that think).

when execute procedure sql management studio, see inserted_id returning..

i ended executescalar , returning scope_identity() directly sp.

if there way of doing , getting value sqlparameter, i'd love hear out.

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
