  • Passing multiple parameters of same column to SQL Server select SP

    - by Bill
    I have a string value in the web.config — for example 2 guids seperated by a ",". I need to query the database dynamically (i.e i have no idea how many values could be seperated by a comma in the web.config) and run a select statement on the table passing these values and getting all that is relevant for example: select * from tablename where columnname = string1 string2 string3 etc etc some strings may only contain 1 guid some may contain 10

  • context.Scale() with non-aspect ratio preserving parameters screws effective lineWith

    - by rrenaud
    I am trying to apply some natural transformations whereby the x axis is remapped to some very small domain, like from 0 to 1, whereas y is remapped to some small, but substantially larger domain, like 0 to 30. This way, drawing code can be nice and clean and only care about the model space. However, if I apply a scale, then lines are also scaled, which means that horizontal lines become extremely fat relative to vertical ones. Here is some sample code. When natural_height is much less than natural_height, the picture doesn't look as intended. I want the picture to look like this, which is what happens with a scale that preserves aspect ratio. rftgstats.c om/canvas_good.png However, with a non-aspect ratio preserving scale, the results look like this. rftgstats.c om/canvas_bad.png <html><head><title>Busted example</title></head> <body> <canvas id=example height=300 width=300> <script> var canvas = document.getElementById('example'); var ctx = canvas.getContext('2d'); var natural_width = 10; var natural_height = 50; ctx.scale(canvas.width / natural_width, canvas.height / natural_height); var numLines = 20; ctx.beginPath(); for (var i = 0; i < numLines; ++i) { ctx.moveTo(natural_width / 2, natural_height / 2); var angle = 2 * Math.PI * i / numLines; // yay for screen size independent draw calls. ctx.lineTo(natural_width / 2 + natural_width * Math.cos(angle), natural_height / 2 + natural_height * Math.sin(angle)); } ctx.stroke(); ctx.closePath(); </script> </body> </html>

  • Urls parameters doesn't encoding correctly!

    - by Ivan90
    I'am using asp.net mvc version 1.0 and I've a problem with some parameter in a url! My url is look like so(http://localhost:2282/Tags/PostList/c#) routes.MapRoute( "TagsRoute", "Tags/PostList/{tag}", new { controller="Tags",Action="PostList",tag = "" } ); In effect the problem is that tag paramter isn't encoding and so simbol # is ignored! I am using an actionlink but maybe with version 1.0 isn't encoding parameter directly! <%=Html.ActionLink(itemtags.Tags.TagName, "PostList","Tags", new { tag = itemtags.Tags.TagName }, new { style = "color:red;" })%> With this actionlink only whitespace are encoding correctly, infact asp.net mvc become asp.net%20mvc and it work fine! But c# isn't encoding :( So I try to use Server.UrlEncode, and in effect it happen some stuff!!! Infact c# became c%2523 but it isn't correct again because hexadecimal of # is %23! Have you some solutions???? Route Contraints? Thanks

  • How to fetch parameters when using the Apache Commons CLI library

    - by Mridang Agarwalla
    I'm using the Apache Commons CLI to handle command line arguments in Java. I've figured out my way around it to a decent extent but I need a little help. I've declared the a and b options and I'm able to access the value using CommandLine.getOptionValue. Usage: myapp [OPTION] [DIRECTORY] Options: -a Option A -b Option B How do I declare and access the DIRECTORY variable? Thank you.

  • jquery function call with parameters

    - by Kaushik Gopal
    Hi a newb question: I have a table with a bunch of buttons like so: <tr class="hr-table-cell" > <td>REcord 1</td> <td> <INPUT type="button" value="Approve" onclick="" /> <INPUT type="button" value="Reject" onclick="" /> <INPUT type="button" value="Delete" onclick="fnDeletePpAppl(222445,704);" /> </td> </tr> <tr class="hr-table-cell" > <td>REcord 1</td> <td align="center" class="hr-table-bottom-blue-border" valign="middle"> <INPUT type="button" value="Approve" onclick="" /> <INPUT type="button" value="Reject" onclick="" /> <INPUT type="button" value="Delete" onclick="fnDeletePpAppl(237760,776);" /> </td> </tr> I have my jquery like so: <script type="text/javascript"> // JQUERY stuff $(document).ready(function(){ function fnDeletePpAppl(empno, applno) { alert('Entering here'); $("form").get(0).empno.value = empno; $("form").get(0).applNo.value = applno; $("form").get(0).listPageAction.value = "delete"; $("form").get(0).action.value = "pprelreqlist.do"; $("form").get(0).submit(); } }); This doesn't seem to work.I thought this means, the function is ready only after the dom is ready. After the dom is ready and i click the button, why is not recognizing the function declaration within the .ready() function? However if i use the function directly: <script type="text/javascript"> function fnDeletePpAppl(empno, applno) { alert('Entering here'); $("form").get(0).empno.value = empno; $("form").get(0).applNo.value = applno; $("form").get(0).listPageAction.value = "delete"; $("form").get(0).action.value = "pprelreqlist.do"; $("form").get(0).submit(); } This works. I want to get my fundamentals straight here... If i do the declaration without the .ready() , does that mean i'm using plain vanilla jscript? If i were to do this with the document.ready - the usual jquery declaration way, what would i have to change to make it work? I understand there are much better ways to do this like binding with buttons etc, but I want to know why this particular way doesn't seem to be working. Thanks. Cheers. K

  • Change a finder method w/ parameters to an association

    - by Sai Emrys
    How do I turn this into a has_one association? (Possibly has_one + a named scope for size.) class User < ActiveRecord::Base has_many :assets, :foreign_key => 'creator_id' def avatar_asset size = :thumb # The LIKE is because it might be a .jpg, .png, or .gif. # More efficient methods that can handle that are OK. ;) self.assets.find :first, :conditions => ["thumbnail = '#{size}' and filename LIKE ?", self.login + "_#{size}.%"] end end EDIT: Cuing from AnalogHole on Freenode #rubyonrails, we can do this: has_many :assets, :foreign_key => 'creator_id' do def avatar size = :thumb find :first, :conditions => ["thumbnail = ? and filename LIKE ?", size.to_s, proxy_owner.login + "_#{size}.%"] end end ... which is fairly cool, and makes syntax a bit better at least. However, this still doesn't behave as well as I would like. Particularly, it doesn't allow for further nice find chaining (such that it doesn't execute this find until it's gotten all its conditions). More importantly, it doesn't allow for use in an :include. Ideally I want to do something like this: PostsController def show post = Post.get_cache(params[:id]) { Post.find(params[:id], :include => {:comments => {:users => {:avatar_asset => :thumb}} } ... end ... so that I can cache the assets together with the post. Or cache them at all, really - e.g. get_cache(user_id){User.find(user_id, :include => :avatar_assets)} would be a good first pass. This doesn't actually work (self == User), but is correct in spirit: has_many :avatar_assets, :foreign_key => 'creator_id', :class_name => 'Asset', :conditions => ["filename LIKE ?", self.login + "_%"] (Also posted on Refactor My Code.)

  • How to call implemented method of generic enum in Java?

    - by Justin Wiseman
    I am trying pass an enum into a method, iterate over that enums values, and call the method that that enum implements on all of those values. I am getting compiler errors on the part "value.getAlias()". It says "The method getAlias() is undefined for the type E" I have attempted to indicate that E implements the HasAlias interface, but it does not seem to work. Is this possible, and if so, how do I fix the code below to do what I want? The code below is only meant to show my process, it is not my intention to just print the names of the values in an enum, but to demonstate my problem. public interface HasAlias{ String getAlias(); }; public enum Letters implements HasAlias { A("The letter A"), B("The letter B"); private final String alias; public String getAlias(){return alias;} public Letters(String alias) { this.alias = alias; } } public enum Numbers implements HasAlias { ONE("The number one"), TWO("The number two"); private final String alias; public String getAlias(){return alias;} public Letters(String alias) { this.alias = alias; } } public class Identifier { public <E extends Enum<? extends HasAlias>> void identify(Class<E> enumClass) { for(E value : enumClass.getEnumConstants()) { System.out.println(value.getAlias()); } } }

  • C++ arrays as parameters, subscript vs. pointer

    - by awshepard
    Alright, I'm guessing this is an easy question, so I'll take the knocks, but I'm not finding what I need on google or SO. I'd like to create an array in one place, and populate it inside a different function. I define a function: void someFunction(double results[]) { for (int i = 0; i<100; ++i) { for (int n = 0; n<16; ++n) //note this iteration limit { results[n] += i * n; } } } That's an approximation to what my code is doing, but regardless, shouldn't be running into any overflow or out of bounds issues or anything. I generate an array: double result[16]; for(int i = 0; i<16; i++) { result[i] = -1; } then I want to pass it to someFunction someFunction(result); When I set breakpoints and step through the code, upon entering someFunction, results is set to the same address as result, and the value there is -1.000000 as expected. However, when I start iterating through the loop, results[n] doesn't seem to resolve to *(results+n) or *(results+n*sizeof(double)), it just seems to resolve to *(results). What I end up with is that instead of populating my result array, I just get one value. What am I doing wrong?

  • Pass parameters to a user control - asp.net

    - by Cristian Boariu
    Hi, I have this user control: <user:RatingStars runat="server" product="<%= getProductId() %>" category="<%= getCategoryId() %>"></user:RatingStars> You see that i fill the product and category by calling two methods: public string getProductId() { return productId.ToString(); } public string getCategoryId() { return categoryId.ToString(); } I do not understand why, in the user control, when i take the data received (product and category) it gives me "<%= getProductId() %" instead of giving the id received from that method... Any help would be kindly appreciated...

  • Scala path dependent return type from parameter

  • Can JMX operations take interfaces as parameters?

    - by Thor84no
    I'm having problems with an MBean that takes a Map<String, Object> as a parameter. If I try to execute it via JMX using a proxy object, I get an Exception: Caused by: javax.management.ReflectionException at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:231) at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:668) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) Caused by: java.lang.IllegalArgumentException: Unable to find operation updateProperties(java.util.HashMap) It appears that it attempts to use the actual implementation class rather than the interface, and doesn't check if this is a child of the required interface. The same thing happens for extended classes (for example declare HashMap, pass in LinkedHashMap). Does this mean it's impossible to use an interface for such methods? At the moment I'm getting around it by changing the method signature to accept a HashMap, but it seems odd that I wouldn't be able to use interfaces (or extended classes) in my MBeans. Edit: The proxy object is being created by an in-house utility class called JmxInvocationHandler. The (hopefully) relevant parts of it are as follows: public class JmxInvocationHandler implements InvocationHandler { ... public static <T> T createMBean(final Class<T> iface, SFSTestProperties properties, String mbean, int shHostID) { T newProxyInstance = (T) Proxy.newProxyInstance(iface.getClassLoader(), new Class[] { iface }, (InvocationHandler) new JmxInvocationHandler(properties, mbean, shHostID)); return newProxyInstance; } ... private JmxInvocationHandler(SFSTestProperties properties, String mbean, int shHostID) { this.mbeanName = mbean + MBEAN_SUFFIX + shHostID; msConfig = new MsConfiguration(properties.getHost(0), properties.getMSAdminPort(), properties.getMSUser(), properties.getMSPassword()); } ... public Object invoke(Object proxy, Method method, Object[] args) throws Throwable { if (management == null) { management = ManagementClientStore.getInstance().getManagementClient(msConfig.getHost(), msConfig.getAdminPort(), msConfig.getUser(), msConfig.getPassword(), false); } final Object result = management.methodCall(mbeanName, method.getName(), args == null? new Object[] {} : args); return result; } }

  • codeIgniter: pass parameter to a select query from previous query

    - by krike
    I'm creating a little management tool for the browser game travian. So I select all the villages from the database and I want to display some content that's unique to each of the villages. But in order to query for those unique details I need to pass the id of the village. How should I do this? this is my code (controller): function members_area() { global $site_title; $this->load->model('membership_model'); if($this->membership_model->get_villages()) { $data['rows'] = $this->membership_model->get_villages(); $id = 1;//this should be dynamic, but how? if($this->membership_model->get_tasks($id)): $data['tasks'] = $this->membership_model->get_tasks($id); endif; } $data['title'] = $site_title." | Your account"; $data['main_content'] = 'account'; $this->load->view('template', $data); } and this is the 2 functions I'm using in the model: function get_villages() { $q = $this->db->get('villages'); if($q->num_rows() > 0) { foreach ($q->result() as $row) { $data[] = $row; } return $data; } } function get_tasks($id) { $this->db->select('name'); $this->db->from('tasks'); $this->db->where('villageid', $id); $q = $this->db->get(); if($q->num_rows() > 0) { foreach ($q->result() as $task) { $data[] = $task; } return $data; } } and of course the view: <?php foreach($rows as $r) : ?> <div class="village"> <h3><?php echo $r->name; ?></h3> <ul> <?php foreach($tasks as $task): ?> <li><?php echo $task->name; ?></li> <?php endforeach; ?> </ul> <?php echo anchor('site/add_village/'.$r->id.'', '+ add new task'); ?> </div> <?php endforeach; ?> ps: please do not remove the comment in the first block of code!

  • Can we have an anonymous struct as template argument?

    - by nonoitall
    The title is pretty self-explanatory, but here's a simplified example: #include <cstdio> template <typename T> struct MyTemplate { T member; void printMemberSize() { printf("%i\n", sizeof(T)); } }; int main() { MyTemplate<struct { int a; int b; }> t; // <-- compiler doesn't like this t.printMemberSize(); return 0; } The compiler complains when I try to use an anonymous struct as a template argument. What's the best way to achieve something like this without having to have a separate, named struct definition?

  • How do i pass a number from a list as a parameter in scheme?

    - by wyatt
    I need to take a number from a list and convert it to a number so that i can pass it as a parameter. im trying to make a 1-bit adder in scheme. i've written the code for the or gate and the xor gate and also the half adder and now im trying to combine them all to make a full adder. im not sure if im going about it the right way. any input will be appreciated thank you. (define or-gate (lambda (a b) (if (= a 1) 1 (if (= b 1) 1 0)))) (define xor-gate (lambda (a b) (if (= a b) 0 1))) (define ha (lambda (a b) (list (xor-gate a b)(and-gate a b)))) (define fa (lambda (a b cin) (or-gate (cdr(ha cin (car (ha a b))))(cdr(ha a b))))) the issue i get when i run the program is that the half adder (ha) function outputs a list as a value and that makes the values incompatible with my other procedures because they require numbers and not lists. i feel like there is a simple solution but i dont know it.

  • Questions on using enums as parameters and if/else conditions

    - by dotnetdev
    Hi, Is it possible to do the following with an enum in C#?: Pass in to a method a selected value of the enum (eg if an enum has members such as Red, Green, Orange, I can pass in Colors.Red). In the method body of the above method which accepts an enum, I can say if (Enum == Colors.Red). What would be the syntax for this? I've always seemed to have stalled on this.

  • Passing parameter to base class constructor or using instance variable?

    - by deamon
    All classes derived from a certain base class have to define an attribute called "path". In the sense of duck typing I could rely upon definition in the subclasses: class Base: pass # no "path" variable here def Sub(Base): def __init__(self): self.path = "something/" Another possiblity would be to use the base class constructor: class Base: def __init__(self, path): self.path = path def Sub(Base): def __init__(self): super().__init__("something/") What would you prefer and why? Is there a better way?
