You can see all files in <code>model.files</code> but then it would be up to you to figure out which was the last one.</p> <p>One alternative is to create the file before adding it to document. You should be able to do:</p> <pre><code>//... File.create({ name: req.param("name"), creator: req.param("userID"); }, function(err, file){ if (err) {return res.serverError(err);} var newFileId = file.id; document.files.add(file.id); document.save(function(err, model) { if (err) {return res.serverError(err);} // the Document modal console.log(model); // the last insert id console.log('last inserted id:', newFileId); res.send(1); }); }); //... </code></pre> <p>In this case <code>newFileId</code> will have the id you need.

3,932,774 | 0 | divide 64bit in two 32bit registers by 32bit <p>I am trying to write an x86 emulator in JavaScript for education purposes. I have already written a compiler and at the moment I am trying to write the x86 emulator in JavaScript.</p> <p>I have however a problem with the DIV instruction. According to <a href="http://siyobik.info/index.php?module=x86&id=72" rel="nofollow">http://siyobik.info/index.php?module=x86&id=72</a> DIV takes a 64bit number as input by interpreting EDX as the higher 32bit and EAX as the lower 32bit. It then divides this number by the DIV parameter and puts the result (if it is not greater than 0xFFFFFFFF) into EAX and the remainder into EDX.</p> <p>As JavaScript does not support 64bit integer I need to apply some tricks. But so far I did not come up with something useful.</p> <p>Does someone here have an idea how to implement that correctly with 32bit arithmetic?</p> |

I'm using this to plot different vehicles (units) on a map in a gps view/controller. Now I'm trying to leverage <code>gmaps4rails</code> to display a map in a different view/controller to display a building (facility) location in the facility show view.</p> <p>On initial page load I display the facility's marker on a map in the proper location. However after a few moments the marker will disappear entirely. I know why this is happening but not how to fix it.</p> <p>I have the following <code>Coffeescript</code> which looks for an <code>ID</code> of <code>#map</code> and calls <code>/units</code> and <code>/gps</code> paths to update the GPS view/map in quasi-realtime.</p> <p><strong>gps.js.coffee</strong></p> <pre><code>$ -> if $("#map").length > 0 setInterval (-> $.getScript "/units" # Get all current locations, find each marker in the map, and update it's position $.getJSON "/gps", (data) -> $.each(data, (i, val) -> marker = $.grep Gmaps.map.markers, (e) -> e.id is val.id marker[0].setPosition(val.lat, val.lng) if marker[0]? ) ), 5000 $('.marker-link').on 'click', -> id = $(this).data("marker-id") marker = $.grep Gmaps.map.markers, (e) -> e.id is id marker[0].showInfowindow() if marker[0]? </code></pre> <p>So the problem is that the default <code>ID</code> for gmaps4rails maps is <code>#map</code>.

Everything works but the marker disappears due to the coffee script calling <code>#map</code>. I don't want to lose this coffeescript functionality as it updates my gps show view with markers properly. I'd like to figure out a way to generate a gmaps4rails map and change the <code>ID</code>.</p> <p><strong>facility.rb</strong></p> <pre><code> acts_as_gmappable process_geocoding: false </code></pre> <p><strong>facilities_controller</strong></p> <pre><code>def show @facility = Facility.find(params[:id]) @marker = @facility.to_gmaps4rails do |facility, marker| #marker.infowindow render_to_string(partial: "unit_infowindow", locals: {unit: unit}) marker.json({id: facility.id}) end respond_to do |format| format.html # index.html.erb format.json { render json: @marker } end end </code></pre> <p><strong>facility show.html.erb</strong></p> <pre><code><div class="well"> <%= gmaps(markers: {data: @marker, options: {rich_marker: true, "auto_zoom" => false}}) %> </div> </code></pre> <p>Is there a way to generate a gmaps4rails map, and override the default <code>ID</code> of <code>#map</code> so I can keep the marker from disappearing and continue to use my coffeescript in my GPS view?</p> <p>If anyone has any suggestions, please let me know.

You are able to use reference of type <code>Base</code> because <code>Derived</code> is also <code>Base</code> (assuming <code>Derived</code> extends <code>Base</code>) hence can be used. But which one should we prefer? The former one because it makes robust design.</p> <p>Consider the Collections Framework in Java which has a <code>List</code> interface and two implementations: <code>ArrayList</code> and <code>LinkedList</code>. We can write our program to use a <code>LinkedList</code> or an <code>ArrayList</code> specifically. But then our code depends on those specific implementations. So we should write our program to depend on the super type, <code>List</code>, instead then our program can work for either of the <code>List</code> implementations. </p> <p>In short this is one rule of OOP design: <code>Program to an interface</code>.</p> |

6,045,094 | 0 | Deleting From DGV -- Index [x] does not have a value <p><strong>The Setup:</strong> I have a two DataGridViews, each bound to a BindingList<> of custom business objects. These grids have a special row containing the mathematical totals of all rows in that grid -- this special row is reflective of a corresponding special object in the BindingList<> (I specify that so that you are aware that this is not a row being added to the DGV, but an object being added to the BindingList<>). </p> <p><strong>The Error:</strong> There comes a time, periodically, where I must find and remove the Totals Row object from the BindingList<> (and thus from the DGV). Here is the original code I was using to do this:</p> <pre><code>private void RemoveTotalRow() { for (int i = UnderlyingGridList.Count - 1; i >= 0; i--) { if (UnderlyingGridList[i].IsTotalRow) UnderlyingGridList.RemoveAt(i); } } </code></pre> <p>(It's not super-important, but the reason I'm cycling through all records is to protect against the possibility that there could be more than one Totals row, by mistake). This code <strong>works flawlessly</strong> for one of the two grids under all circumstances. However, on the second grid I get the following error when the RemoveAt method is called:</p> <pre><code>The following exception occurred in the DataGridView: System.IndexOutOfRangeException: Index 5 does not have a value. at System.Windows.Forms.CurrencyManager.get_Item(Int32 index) at System.Windows.Forms.DataGridView.DataGridViewDataConnection.GetError(Int32 rowIndex) To replace this default dialog please handle the DataError event. </code></pre> <p>...where '5' is the index of the totals row. <a href="http://stackoverflow.com/questions/890950/datagridview-on-winforms-throws-exception-when-i-delete-a-record">I found this question</a>, which is essentially the same, except that the accepted answer is to either: 1) Not use an underlying list, which I must do, or 2) Delete from the grid instead of from the list. I have tried #2 by replacing the innermost method call from my code example above with this:</p> <pre><code>if (UnderlyingGridList[i].IsTotalRow) brokenDataGrid.Rows.RemoveAt(i); </code></pre> <p>This throws the same error. <a href="http://stackoverflow.com/questions/1630200/net-datagridview-index-0-does-not-have-a-value">I also found this question</a>, which suggests rebinding after the change - however, this is not feasible as it is possible for this code to be called once per second and if the list is too heavily populated it will make the grid unusable (I know this from bad experiences).</p> <p>I could just handle the grid's DataError event, but I'd rather not have the thing popping a million errors per minute, even if they are silent. Any help would be greatly appreciated.</p> |

11,609,062 | 0 | ActiveMQ CLIENT on Java 1.4 <p>We are using Active MQ in the most current version 5.6.0. Now we have the problem that a new client has to be connected, unfortunately this client is developed with IBM JDK 1.4. Adding ActiveMQ to the application lead to the following error: </p> <pre><code>UNEXPECTED ERROR OCCURRED: org/apache/activemq/ActiveMQConnectionFactory (Unsupported major.minor version 50.0) STACK TRACE: java.lang.UnsupportedClassVersionError: org/apache/activemq/ActiveMQConnectionFactory (Unsupported major.minor version 50.0) </code></pre> <p>We don't want to switch to an older ActiveMQ version, since there are other applications using the current version.

For example is it possible to use an ActiveMQ 4.0 client to connect to Active MQ 5.6.0? Is it possible to use any other protocol for this purpose? Has anyone a succesful solution running?</p> <p>If I have to use retrotranslator which is the minimum set on jars I have to translate? Has anyone the experience with IBM JDK 1.4? </p> <p>Thanks for your answers!</p> |
