visual studio - C# 4.0/EF - Server-generated keys and server-generated values are not supported by SQL Server Compact -

-

i have moved 1 of projects vs2010/fx4.0 , using sql ce database backing store. since moving version of .net getting error:

server-generated keys , server-generated values not supported sql server compact.

my table was defined pk of username (string) & dooropen (datetime) sqlce required there pk on every table in fx3.5. in fx4.0 stumped. i've googled , every answer found was:

sqlce not support auto-generating values (which not needing) put guid id on there , populate code.

i tried approach , still getting same error!

sqlce:

create table [importdooraccesses] (     [rawdata] nvarchar(100)  not null,     [dooropen] datetime  not null,     [username] nvarchar(100)  not null,     [cardnumber] bigint  not null,     [door] nvarchar(4000)  not null,     [imported] datetime  not null,     [id] uniqueidentifier  not null -- new column );  alter table [importdooraccesses] add constraint [pk_importdooraccesses]     primary key ([id] );

the constraint used be:

alter table [importdooraccesses] add constraint [pk_importdooraccesses]     primary key ([dooropen],[username]);

code:

foreach (dto.dooraudit newdooraudit in datatransferobject) {     if (newdooraudit.doinsert)     {         myentities.addtoimportdooraccesses(new importdooraccess         {             cardnumber = newdooraudit.cardnumber,             door = newdooraudit.door,             dooropen = newdooraudit.dooropen,             imported = newdooraudit.imported,             rawdata = newdooraudit.rawdata,             username = newdooraudit.username,             id = guid.newguid()  // - here suggested!         });     } } myentities.savechanges();

so, what? bug in ef4? doing wrong?

note:

going through edmx file (right-click, open with, xml) found 1 of date columns set storegeneratedpattern="identity". 

  <entitytype name="importdooraccesses">     <key>       <propertyref name="id" />     </key>     <property name="rawdata" type="nvarchar" nullable="false" maxlength="100" />     <property name="dooropen" type="datetime" nullable="false" />     <property name="username" type="nvarchar" nullable="false" maxlength="100" />     <property name="cardnumber" type="bigint" nullable="false" />     <property name="door" type="nvarchar" nullable="false" />     <property name="imported" type="datetime" storegeneratedpattern="identity" nullable="false" />     <property name="id" type="uniqueidentifier" nullable="false" />   </entitytype>

i switched pretty model view , clicked on every single column in database make sure not set. pita sure. looks perfect little tool/add-in needs created...

the important thing check edmx file , make sure property/column doesn't have storegeneratedpattern of identity in there.

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...

php - Replacing tags in braces, even nested tags, with regex -

-
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."
