  • Building 'flat' rather than 'tree' LINQ expressions

    - by Ian Gregory
    I'm using some code (available here on MSDN) to dynamically build LINQ expressions containing multiple OR 'clauses'. The relevant code is var equals = values.Select(value => (Expression)Expression.Equal(valueSelector.Body, Expression.Constant(value, typeof(TValue)))); var body = equals.Aggregate<Expression>((accumulate, equal) => Expression.Or(accumulate, equal)); This generates a LINQ expression that looks something like this: (((((ID = 5) OR (ID = 4)) OR (ID = 3)) OR (ID = 2)) OR (ID = 1)) I'm hitting the recursion limit (100) when using this expression, so I'd like to generate an expression that looks like this: (ID = 5) OR (ID = 4) OR (ID = 3) OR (ID = 2) OR (ID = 1) How would I modify the expression building code to do this?

  • Jpa subclass mapping

    - by Roy Chan
    I am making a POS like system. I wonder how to map subclass using JPA (this is for my DAO). Product class has product details and OrderProduct class has information about the Product and details about the order. @Entity @Table(name="products") public class Product implements Serializable{ @Id @Column(name="id") @GeneratedValue(strategy = GenerationType.AUTO public int getId(){ return id;} /** Other get/set methods */ } @Entity @Table(name="order_products") public class OrderProduct extends Product{ @Id @Column(name="id") @GeneratedValue(strategy = GenerationType.AUTO) public int getId(){ return id;} /** Other get/set methods */ } I got complain about duplicate @Id. But OrderProduct class really need another id than the product one. How should I map this? DB is something like this Table products id int name varchar(32) Table order_product id int quantity int productid int fk referencing product table Would @IdClass or @AttributeOverride help?

  • In an Android TextView, is it possible to insert paragraphs?

    - by johnrock
    Below is an example of the type of problem that I have. I have data in a pojo that I need to display in a textview... the data has pseudo code that denotes each paragraph with [p] I would like to somehow parse the [p]'s into paragraphs when they are displayed in the textview. Can this be done? Is there something I can substitute for the [p] that will make a new paragraph in the textview? Question question = new Question(); question.setText("Here is the first paragraph.[p] And this should be the second."); TextView view = (TextView) findViewById(R.id.qtext); view.setText(question.getParsedText());

  • How do I obtain and use a CVSNT commit ID?

    - by skiphoppy
    I saw a reference on another question to a unique commit id auto-generated by CVSNT that marks each commit. I think most people in my department are using CVSNT or frontends to it. I found commit identifiers described in the CVSNT manual, but there is no explanation about how to determine what the CVSNT commit identifier is for a particular revision of a file. Is there a way to do this? I'd like to find out what commit identifiers are being generated for other people's checkins so I can group together the files involved in their commits.

  • In SharePoint, how can the "Issue ID" column of an issues list be included in the detail form (DispF

    - by Jesse C. Slicer
    We've created a pretty standard issue tracking system based off of SharePoint's template with just a few extra columns. On the list view (AllItems.aspx), the first column is called "Issue ID" and has a number. Our developers and QC use that number in discussions. However, that number doesn't seem to want to show up on the detail form (DispForm.aspx) nor in the alert email. Can this field be included in at least one of these communication methods? If so, how? Thank you.

However, I need to distinguish between users who are using my clipboard through a unique id. Basically, I want to be able identify a person who is sat at one PC with one or more copies of visual studio (or similar) open. How do I do that? ps: This is at design-time. pps: It's not critical that it should work between copies of visual studio. One copy would be fine, or even one design surface.

    Hi Maybe it's simple question, but it's my first time with EF + win app so ... I'm building win app with EF by adding edmx as data source then drag and drop the tables to get navigator and binding source .. when I press the add button in the navigator it allows me to enter new data but when I save the context I get NULL data for all fields except the auto increment field ( the ID field ).... What should I do to save many entries ...? DO I have to loop over all the entities in the binding source and add them to the context ?? Thanx in advance Update: I forgot to say that when i use data grid view it adds the items correctly but with "Details" it didn't ..

  • php foreach looping twice

    - by Jack
    Hi, I am trying to loop through some data from my database but it is outputting it twice. $fields = 'field1, field2, field3, field4'; $idFields = 'id_field1, id_field2, id_field3, id_field4'; $tables = 'table1, table2, table3, table4'; $table = explode(', ', $tables); $field = explode(', ', $fields); $id = explode(', ', $idFields); $str = 'Egg'; $i=1; while ($i<4) { $f = $field[$i]; $idd = $id[$i]; $sql = $writeConn->select()->from($table[$i], array($f, $idd))->where($f . " LIKE ?", '%' . $str . '%'); $string = '<a title="' . $str . '" href="' . $currentProductUrl . '">' . $str . '</a>'; $result = $writeConn->fetchAssoc($sql); foreach ($result as $row) { echo 'Success! Found ' . $str . ' in ' . $f . '. ID: ' . $row[$idd] . '.<br>'; } $i++; } Outputting: Success! Found Egg in field3. ID: 5. Success! Found Egg in field3. ID: 5. Could someone please explain why it is looping through both the indexed and associative values? UPDATE I did some more playing around and tried the following. $fields = 'field1, field2, field3, field4'; $idFields = 'id_field1, id_field2, id_field3, id_field4'; $tables = 'table1, table2, table3, table4'; $table = explode(', ', $tables); $field = explode(', ', $fields); $id = explode(', ', $idFields); $str = 'Egg'; $i=1; while ($i<4) { $f = $field[$i]; $idd = $id[$i]; $sql = $writeConn->select()->from($table[$i], array($f, $idd))->where($f . " LIKE ?", '%' . $str . '%'); $string = '<a title="' . $str . '" href="' . $currentProductUrl . '">' . $str . '</a>'; $sth = $writeConn->prepare($sql); $sth->execute(); $result = $sth->fetch(PDO::FETCH_ASSOC); foreach ($result as $row) { echo 'Success! Found ' . $str . ' in ' . $f . '. ID: ' . $row[$idd] . '.<br>'; } $i++; } The interesting thing is that this outputs the below: Success! Found Egg in field3. ID: E. Success! Found Egg in field3. ID: E. Success! Found Egg in field3. ID: 5. Success! Found Egg in field3. ID: 5. Success! Found Egg in field3. ID: E. Success! Found Egg in field3. ID: E. Success! Found Egg in field3. ID: 5. Success! Found Egg in field3. ID: 5. I have also tried adding $i to the output and this outputs 2 as expected. If I change fetch(PDO::FETCH_BOTH) to fetch(PDO::FETCH_ASSOC) the output is as follows: Success! Found Egg in field3. ID: E. Success! Found Egg in field3. ID: E. Success! Found Egg in field3. ID: 5. Success! Found Egg in field3. ID: 5. This has been bugging me for too long, so if anyone could help I would be very appreciative!

DECLARE @table TABLE(val VARCHAR(255) NULL) INSERT INTO @table (val) VALUES('a') INSERT INTO @table (val) VALUES('b') INSERT INTO @table (val) VALUES('c') INSERT INTO @table (val) VALUES('d') INSERT INTO @table (val) VALUES(NULL) select val from @table where val not in ('a') I would expect this to return b, c, d, NULL but instead it returns b, c, d Why is this the case? Is NULL not evaluated? Is NULL somehow in the set 'a'?

  • Jquery nested div .click event

    - by Sylph
    The link #loadContent will loads tree.html. Upon success loading the content, the script reinitialize some functions which is in tree.html. However, I am unable to get the .click event to function in the loaded content. Index.html <a href="#" id="loadContent">Load</a> <script type="text/javascript"> $(function() { $("#loadContent").click(function() { $.ajax({ url: "tree.html" ,success: function(data) { $('#result').html(data); $("#demo_1").tree({ rules : { use_max_children : false, use_max_depth : false }, callback : { onmove : function (NODE,REF_NODE,TYPE,TREE_OBJ,RB) { alert(TREE_OBJ.get_text(NODE) + " " + TYPE + " " + TREE_OBJ.get_text(REF_NODE)); } } }); } }); }); }); </script> <script type="text/javascript" class="source"> $(function () { $.tree.drag_start = function () { $("#log").append("<br />Drag start "); }; $.tree.drag = function () { $("#log").append(" ."); }; $.tree.drag_end = function () { $("#log").append(" Drag end<br />"); }; $("#demo_1").tree({ rules : { use_max_children : false, use_max_depth : false }, callback : { onmove : function (NODE,REF_NODE,TYPE,TREE_OBJ,RB) { alert(TREE_OBJ.get_text(NODE) + " " + TYPE + " " + TREE_OBJ.get_text(REF_NODE)); } } }); $("#demo_2").tree({ rules : { use_max_children : false, use_max_depth : false }, callback : { onmove : function (NODE,REF_NODE,TYPE,TREE_OBJ,RB) { alert(TREE_OBJ.get_text(NODE) + " " + TYPE + " " + TREE_OBJ.get_text(REF_NODE)); } } }); }); </script> <div class="demo" id="demo_2"> <ul> <li id="phtml_1" class="open"><a href="#"><ins>&nbsp;</ins>Root node 1</a> <ul> <li id="phtml_2"><a href="#"><ins>&nbsp;</ins>Child node 1</a></li> <li id="phtml_3"><a href="#"><ins>&nbsp;</ins>Child node 2</a></li> <li id="phtml_4"><a href="#"><ins>&nbsp;</ins>Some other child node with longer text</a></li> </ul> </li> <li id="phtml_5"><a href="#"><ins>&nbsp;</ins>Root node 2</a></li> </ul> </div> <div id="result"></div><br> <div id="log"></div> Tree.html <div class="demo" id="demo_1"> <ul> <li id="phtml_1" class="open"><a href="#"><ins>&nbsp;</ins>Root node 1</a> <ul> <li id="phtml_2"><a href="#"><ins>&nbsp;</ins>Child node 1</a></li> <li id="phtml_3"><a href="#"><ins>&nbsp;</ins>Child node 2</a></li> <li id="phtml_4"><a href="#"><ins>&nbsp;</ins>Some other child node with longer text</a></li> </ul> </li> <li id="phtml_5"><a href="#"><ins>&nbsp;</ins>Root node 2</a></li> <li><a class="preset_text" id="1">model 1</a> </li> <li><a class="preset_text" id="2">model 2</a></li> </ul> </div> <script type="text/javascript"> $(document).ready(function() { $('.preset_text').click(function(){ var target = $(this).attr("id"); alert(target); }); }); </script> In tree.html, I am unable to get the alert(target). However, If I moved this section out from the "div #demo_1" in tree.html, I am able to receive alert(target). <a class="preset_text" id="1">model 1</a> <a class="preset_text" id="2">model 2</a> How can I get to detect the item clicked in the div demo_1 ? Thanks

  • jQuery: How to remove this code redundancy?

    - by Mark
    clone.find('[id]').each(function() { id = $(this).attr('id'); ind = id.search(/\d+$/); $(this).attr('id', id.substr(0,ind)+id_counter); }); clone.find('[for]').each(function() { id = $(this).attr('for'); ind = id.search(/\d+$/); $(this).attr('for', id.substr(0,ind)+id_counter); }); I know I can find elements that have either the id attribute or the for attribute, but then how do I know which one I need to set?

  • menuitem id in xml format can't be an integer? huh. really?

    - by misbell
    ok, in menu.add, you add an integer menuitem id. But when you specify the menu in xml, @+id can't take an integer, so you can't test the id for the menu item as an integer in a switch statement. What obvious thing am I missing, because surely an inconsistency this bone-stupid couldn't have passed muster with all those wonderful geniuses at Google. on top of that, when I give the menu item a name like "@+id/myMenuItem", item.getItemId() returns an integer, a long one, which I guess is a representation of the hex pointer.

  • ASP.NET: How to assign ID to a field in DetailsView?

    - by jawonlee
    I have a master-detail page, in which I use GridView to display multiple rows of data, and DetailsView + jQuery dialog to display the details of a single records. only one DetailsView is open at a time. I need to be able to pull out a single field of the open DetailsView, for manipulation using JavaScript. Is there a way to give a unique ID to a given field in DetailsView, so I can use getElementByID? Or is there another way to accomplish what I'm trying to do? Thank you in advance.
