  • ASP.NET SqlDataSource update and create FK reference

    - by William
    The short version: I have a grid view bound to a data source which has a SelectCommand with a left join in it because the FK can be null. On Update I want to create a record in the FK table if the FK is null and then update the parent table with the new records ID. Is this possible to do with just SqlDataSources? The detailed version: I have two tables: Company and Address. The column Company.AddressId can be null. On my ascx page I am using a SqlDataSource to select a left join of company and address and a GridView to display the results. By having my UpdateCommand and DeleteCommand of the SqlDataSource execute two statements separated by a semi-colon I am able to use the GridView's Edit and Delete functionality to update both table simultaneously. The problem I have is when the Company.AddressId is null. What I need to have happen is have the data source create a record in the Address table and then update the Company table with the new Address.ID then proceed with the update as usual. I would like to do this with just data sources if possible for consistency/simplicity sake. Is it possible to have my data source do this, or perhaps add a second data source to the page to handle some of this? Once I have that working I can probably figure out how to make it work with the InsertCommand as well but if you are on a roll and have an answer for how to make that fly as well feel free to provide it. Thanks.

  • Breadcrumbs in Fusebox 4/5

    - by Jordan Reiter
    I'm wondering if anyone has come up with a clean way to generate a breadcrumbs trail in Fusebox. Specifically, is there a way of keeping track of "where you are" and having that somehow generate the breadcrumbs for you? So, for example, if you're executing /index.cfm?fuseaction=Widgets.ViewWidget&widget=1 and the circuit structure is something like /foo/bar/widgets/ then somehow the system automatically creates an array like: [ { title: 'Foo', url: '#self#?fuseaction=Foo.Main' }, { title: 'Bar', url: '#self#?fuseaction=Bar.Main' }, { title: 'Widgets', url: '#self#?fuseaction=Widgets.Main' }, { title: 'Awesome Widget', url: '' } ] Which can then be rendered as Foo Bar Widgets Awesome Widget Right now it seems the only way to really do this is to create the structure for each fuseaction in a fuse of some kind (either the display fuse or a fuse dedicated to creating the crumbtrail).

  • Display X divs randomly out of a possible Y.

    - by Jordan
    How do I randomly display 3 divs out of a possible 10 in total? This is what I have tried so far: HTML: <div id="1">Content 1</div> <div id="2">Content 2</div> <div id="3">Content 3</div> <div id="4">Content 4</div> <div id="5">Content 5</div> <div id="6">Content 6</div> Javascript: function randomiseDiv() { // Define how many divs we have var divCount = 6; // Get our random ID (based on the total above) var randomId = Math.floor(Math.random()*divCount+1); // Get the div that's been randomly selectted var chosenDiv= document.getElementById(randomId); // If the content is available on the page if (chosenDiv) { // Update the display chosenDiv.style.display = 'block'; } } window.onload = randomiseDiv; I would prefer a PHP solution, although anything at this stage would be beneficial.

  • .Net LoginControls - User can't logout in Firefox

    - by Jordan Foreman
    Basically, the logout link doesn't do anything, but only in Firefox. (I can login and out freely from other browsers) There really isn't a whole lot of information I can really give other than that, since I'm still new to this project and .net as a whole, and know almost nothing about the login controls. So if someone else has experienced a similar issue in the past, and can recognize the issue with the little info I have, that would be great! If not, sorry for the lack of depth, but its all I have. If it helps, here is the code for where the logout link is: <LoggedInTemplate> ... <asp:LoginStatus ID="HeadLoginStatus" runat="server" LogoutAction="Redirect" LogoutText="Log Out" LogoutPageUrl="~/Anonymous/Login.aspx" /> </LoggedInTemplate>

  • How to Retrieve Values of A Dynamically Created Control's Child Controls on PostBack?

    - by Jordan
    Given: I have a custom server control in the markup of an aspx page. This control creates child controls in its CreateChildControls() method (e.g. it retrieves content from a database and based on that content dynamically creates either a CheckBoxList or a RadioButtonList) Now I understand that I cannot access the dynamically created controls on postback unless I add them again on Page_Init or Page_PreInit (as per here). My question is, how do I add them again explicitly in Page_Init or Page_PreInit if they are just going to be added yet again when we get around to calling Render() on each of the custom server controls? I'm very certain this is not a unique problem, so there must be a best practice way of doing it...I just don't know what it is :/

    We have a new junior developer and I want him to start reading up on various topics in order to broaden his horizons.

  • Openlayers and Bing Maps (POLYGONS)

    - by Jordan
    When trying to draw polygons onto a bing map, the initial marker is set differently on the map. How can I fix this? OpenLayers Bing Example <script src="OpenLayers.js"></script> <script> var map; function init(){ map = new OpenLayers.Map("map"); map.addControl(new OpenLayers.Control.LayerSwitcher()); var shaded = new OpenLayers.Layer.VirtualEarth("Shaded", { type: VEMapStyle.Shaded }); var hybrid = new OpenLayers.Layer.VirtualEarth("Hybrid", { type: VEMapStyle.Hybrid }); var aerial = new OpenLayers.Layer.VirtualEarth("Aerial", { type: VEMapStyle.Aerial }); var POLY_LAYER = new OpenLayers.Layer.Vector(); map.addLayers([shaded, hybrid, aerial, POLY_LAYER]); map.setCenter(new OpenLayers.LonLat(-110, 45), 3); var polygon = new OpenLayers.Control.DrawFeature(POLY_LAYER, OpenLayers.Handler.Polygon); map.addControl(polygon); polygon.activate(); } </script> Bing Example <div id="tags"> Bing, Microsoft, Virtual Earth </div> <p id="shortdesc"> Demonstrates the use of Bing layers. </p> <div id="map" class="smallmap"></div> <div id="docs">This example demonstrates the ability to create layers using tiles from Bing maps.</div> Of course the above is being initialized and page works. You can draw the polygon shapes. Notice if you zoom in or out one time, the markers are set at the correct coordinates. My app I was testing this on is really using the bing maps API keys and not VirtualEarth. But it's doing a similar thing. Is this an Openlayers bug? The below source came directly from the open layers example site, I just added and activated polygons to the map. Please let me know how I can fix this for using the Bing Map API.. I've been stuck on this for HOURS! :(

  • IE JavaScript Mystery

    - by William Calleja
    I have the following JavaScript function function headerBanner(){ var current = $('.bannerImages img:nth-child('+bannerIndex+')').css('display', 'none'); if(bannerIndex== $('.bannerImages img').size()){ bannerIndex= 1; }else{ bannerIndex= (bannerIndex*1)+1; } var next = $('.bannerImages img:nth-child('+bannerIndex+')').css('display', 'block'); } In every browser on the planet, with the exception of IE (8, 7 or less), the above code is working correctly. In Internet Explorer it's going through it and having no effect. I've put alerts at every line of the function and they all fire, even in IE, but the banner simply doesn't change. Is there any reason as to why this is so?

  • How do I get events to execute on the "main thread"

    - by William DiStefano
    I have 2 classes, one is frmMain a windows form and the other is a class in vb.NET 2003. frmMain contains a start button which executes the monitor function in the other class. My question is, I am manually adding the event handlers -- when the events are executed how do I get them to excute on the "main thread". Because when the tooltip balloon pops up at the tray icon it displays a second tray icon instead of popping up at the existing tray icon. I can confirm that this is because the events are firing on new threads because if I try to display a balloon tooltip from frmMain it will display on the existing tray icon. Here is a part of the second class (not the entire thing): Friend Class monitorFolders Private _watchFolder As System.IO.FileSystemWatcher = New System.IO.FileSystemWatcher Private _eType As evtType Private Enum evtType changed created deleted renamed End Enum Friend Sub monitor(ByVal path As String) _watchFolder.Path = path 'Add a list of Filter to specify _watchFolder.NotifyFilter = IO.NotifyFilters.DirectoryName _watchFolder.NotifyFilter = _watchFolder.NotifyFilter Or IO.NotifyFilters.FileName _watchFolder.NotifyFilter = _watchFolder.NotifyFilter Or IO.NotifyFilters.Attributes 'Add event handlers for each type of event that can occur AddHandler _watchFolder.Changed, AddressOf change AddHandler _watchFolder.Created, AddressOf change AddHandler _watchFolder.Deleted, AddressOf change AddHandler _watchFolder.Renamed, AddressOf Rename 'Start watching for events _watchFolder.EnableRaisingEvents = True End Sub Private Sub change(ByVal source As Object, ByVal e As System.IO.FileSystemEventArgs) If e.ChangeType = IO.WatcherChangeTypes.Changed Then _eType = evtType.changed notification() End If If e.ChangeType = IO.WatcherChangeTypes.Created Then _eType = evtType.created notification() End If If e.ChangeType = IO.WatcherChangeTypes.Deleted Then _eType = evtType.deleted notification() End If End Sub Private Sub notification() _mainForm.NotifyIcon1.ShowBalloonTip(500, "Folder Monitor", "A file has been " + [Enum].GetName(GetType(evtType), _eType), ToolTipIcon.Info) End Sub End Class

  • How do I determine inactivity in a MVVM application?

    - by Jordan
    I have an MVVM kiosk application that I need to restart when it has been inactive for a set amount of time. I'm using Prism and Unity to facilitate the MVVM pattern. I've got the restarting down and I even know how to handle the timer. What I want to know is how to know when activity, that is any mouse event, has taken occurred. The only way I know how to do that is by subscribing to the preview mouse events of the main window. That breaks MVVM thought, doesn't it? I've thought about exposing my window as an interface that exposes those events to my application, but that would require that the window implement that interface which also seems to break MVVM.

  • Django dictionary in templates: Grab key from another objects attribute

    - by Jordan Messina
    I have a dictionary called number_devices I'm passing to a template, the dictionary keys are the ids of a list of objects I'm also passing to the template (called implementations). I'm iterating over the list of objects and then trying to use the object.id to get a value out of the dict like so: {% for implementation in implementations %} {{ number_devices.implementation.id }} {% endfor %} Unfortunately number_devices.implementation is evaluated first, then the result.id is evaluated obviously returning and displaying nothing. I can't use parentheses like: {{ number_devices.(implementation.id) }} because I get a parse error. How do I get around this annoyance in Django templates? Thanks for any help!

  • Bizarre Escape Character Question

    I have the following c# code embedded in a literal <% %> of a c# asp.net page string commandString = "SELECT tblData.Content " + "FROM tblData " + "WHERE (tblData.ref = N\'%"+myCurrentREF+"%\')"; This is breaking my code since it apparently cannot use the \' escape character. Why is it so? other escape characters like \" are working so why isn't \' working?

  • Binding Data into a Resource

    - by Jordan
    How do you bind data from the view model into an object in the resources of the user control? Here is a very abstract example: <UserControl ... xmlns:local="clr-namespace:My.Local.Namespace" Name="userControl"> <UserControl.Resources> <local:GroupingProvider x:Key="groupingProvider" GroupValue="{Binding ???}" /> </UserControl.Resources> <Grid> <local:GroupingConsumer Name="groupingConsumer1" Provider={StaticResource groupingProvider"} /> <local:GroupingConsumer Name="groupingConsumer2" Provider={StaticResource groupingProvider"} /> </Grid> </UserControl> How do I bind GroupValue to a property in the view model behind this view. I've tried the following: <local:GroupingProvider x:Key="groupingProvider" GroupValue="{Binding ElementName=userControl, Path=DataContext.Property}"/> But this doesn't work. Edit: GroupProvider extends DependencyObject and GroupValue is the name of a DependencyProperty. I'm getting an debugging message telling me that the property to which I am binding doesn't exist.

  • missing table in SQLite with specific version of HTC DESIRE HD

    - by William
    My application has a SQLite database in the asset folder. When the user launches my application, the database is created and the tables too. This works fine with a lot of devices (Nexus One, Htc Magic, SGS, X10… and even Htc Desire HD v2.2). My application works with all versions of Android (tested on my device (1.6, 2.2, 2.2.1 Htc Magic) and on the emulator (v1,5 until v2.3). I have just a problem with HTC DESIRE HD v2.2.1 1.72.405.3. The logcat: android.database.sqlite.SQLiteException: no such table: LISTE: , while compiling: select _id from LISTE at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2833) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2854) at android.app.ActivityThread.access$2300(ActivityThread.java:136) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2179) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:143) at android.app.ActivityThread.main(ActivityThread.java:5068) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:521) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:858) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616) at dalvik.system.NativeStart.main(Native Method) Caused by: android.database.sqlite.SQLiteException: no such table: LISTE: , while compiling: select _id from LISTE at android.database.sqlite.SQLiteCompiledSql.native_compile(Native Method) at android.database.sqlite.SQLiteCompiledSql.compile(SQLiteCompiledSql.java:91) at android.database.sqlite.SQLiteCompiledSql.(SQLiteCompiledSql.java:64) at android.database.sqlite.SQLiteProgram.(SQLiteProgram.java:80) at android.database.sqlite.SQLiteQuery.(SQLiteQuery.java:46) at android.database.sqlite.SQLiteDirectCursorDriver.query(SQLiteDirectCursorDriver.java:53) at android.database.sqlite.SQLiteDatabase.rawQueryWithFactory(SQLiteDatabase.java:1417) at android.database.sqlite.SQLiteDatabase.rawQuery(SQLiteDatabase.java:1387) ... 11 more My application create the database but it doesn’t copy the tables of the file of the asset folder in data\data\packagename\databases\mydatabase. My code: public void createDataBase() throws IOException{ boolean dbExist = checkDataBase(); if(dbExist){ //do nothing - database already exist }else{ //By calling this method and empty database will be created into the default system path //of your application so we are gonna be able to overwrite that database with our database. this.getReadableDatabase(); try { copyDataBase(); } catch (IOException e) { throw new Error("Error copying database"); } } } private void copyDataBase() throws IOException{ //Open your local db as the input stream InputStream myInput = myContext.getAssets().open(DB_NAME); // Path to the just created empty db String outFileName = DB_PATH + DB_NAME; //Open the empty db as the output stream OutputStream myOutput = new FileOutputStream(outFileName); //transfer bytes from the inputfile to the outputfile byte[] buffer = new byte[1024]; int length; while ((length = myInput.read(buffer))!= -1){ if (length > 0){ myOutput.write(buffer, 0, length); } } //Close the streams myOutput.flush(); myOutput.close(); myInput.close(); } I think that the copydatabase function has a problem but I don't see. This code works fine with all devices except the HTC DESIRE HD v2.2.1 1.72.405.3. What problems might exist here for the HTC Desire with the given version above? How can this be remedied?
