  • Is it possible to *optionally* override a theme in Drupal 6?

    - by David Semeria
    I want to override the theming of only one (custom) menu. I can do this with phptemplate_menu_tree() but - of course - it overrides the rendering of all menus. I've tried returning FALSE (an obvious technique IMO) if the menu is not the specific one I want to override - but this doesn't cause the overridden theme function to be called. My only alternative (when the menu is anything other than the specific one) is to call the overridden function from within phptemplate_menu_tree() - but this seems to defeat the whole point of the override system, since the default rendering function will be hard-coded therein. I hope the explanation is clear, and any help is greatly appreciated - tks.

  • how can an application use port 80/HTTP without conflicting with browsers?

    - by John
    If I understand right, applications sometimes use HTTP to send messages, since using other ports is liable to cause firewall problems. But how does that work without conflicting with other applications such as web-browsers? In fact how do multiple browsers running at once not conflict? Do they all monitor the port and get notified... can you share a port in this way? I have a feeling this is a dumb question, but not something I ever thought of before, and in other cases I've seen problems when 2 apps are configured to use the same port.

  • Getting the callers of a specific function

    - by robUK
    Hello, GNU Emacs 23.1.1 I am just wondering is there any feature in emacs where I can find out what functions call a specific function. In my code, I normally have to do a search on the function name to see what functions calls it. It would be nice if I could display all the names of the functions where this specific function is being called from. many thanks for any suggestions,

  • LinkButtons Created Dynamically in a Repeater Don't Fire ItemCommand Event

    - by 5arx
    Hi. I've got a repeater that's used to display the output of a dynamic report that takes criteria from webcontrols on the page. Within the repeater's ItemDataBound method I'm adding controls (Linkbuttons for sorting by column values) dynamically to the header of the repeater based on values selected in a checkbox list and at this point setting the CommandArgument and CommandName properties of the linkbuttons. The issue is that when the linkbuttons are clicked they don't fire the ItemCommand event although they are clearly being correctly created and added to the header (there is some additional code to set the cssClass, text etc. and this works as expected.) The first column header in the repeater is set in the markup and the itemcommand event fires correctly on this one only. When the other column headers are clicked the repeater rebinds as programmed, but the columns are not dynamically re-generated. I would really appreciate somebody explaining what I'm doing wrong - afaik I'm following the approved way of doing this :-( Simplified code follows: Nightmare.ascx <asp:repeater runat="server" id="rptReport" OnItemDataBound="rptResults_ItemDataBound" OnItemCommand="rptResults_ItemCommand" EnableViewState="true"> <headertemplate> <table> <tr runat="Server" id="TRDynamicHeader"> <th> <!-- This one works --> <asp:Linkbutton runat="server" CommandName="sort" commandArgument='<%# Eval("Name")%?' /> </th> <!-- additional header cells get added dynamically here --> </tr> </headertemplate> <itemTemplate> <td><%# Eval("Name")</td> ... </itemTemplate> </asp:repeater> Nightmare.ascx.cs protected void PageLoad(object sender, eventArgs e){ if (! isPostback){ setupGui();//just binds dropdowns etc. to datasources } } protected void btnRunReport_Click(...){ List<ReportLines> lstRep = GetReportLines(); rptReport.DataSource = lstRep; repReport.DataBind(); } protected void rptReport_ItemDataBound (...){ if (e.Item.ItemType == ListItemType.Header) { foreach (ListItem li in chbxListBusFuncs.Items) { if (li.Selected) { th = new HtmlTableCell(); lb = new LinkButton(); lb.CssClass = "SortColHeader"; lb.CommandArgument = li.Text.Replace(" ", ""); lb.CommandName = "sort"; lb.Text = li.Text; th.Controls.Add(lb); ((HtmlTableRow)e.Item.FindControl("TRDynamicHeader")).Cells.Add(th); } } } if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) { //Row level customisations, totals calculations etc. } } <!-- this only gets called when the 'hardcoded' linkbutton in the markup is clicked. protected void rptReport_ItemCommand(object sender, Eventargs e){ lblDebug.Text = string.Format("Well? What's Happening? -> {0}:{1}", e.CommandName, e.CommandArgument.ToString()); } (The only thing that can call the runreport routine is a single button on the page, not shown in the code snippet above.)

  • Android Login - Best implementation

    - by perdian
    Hi everybody, I'm planning to implement an Android application that requires a login screen. If the user opens the activity something like this should happen: If user is logged in, goto 3 If user is not logged in open the login screen and perfom login Show my application content So, what's the "correct" way of implementing a login? Implement a StartActivity that perfoms the check if the user is logged in, implement a LoginActivity that implements the logging and an ApplicationActivity that actually implements the application logics? Implement just one Activity and handle the login by using multiple views which I show according to the application state? Are there any examples or tutorials for this scenario?

    - by mydiscogr
    Hi, I've a little problem, I don't really understand if I can use addEventListener more than one time on the same object (and same callback function) if this case can I have a problem of overflow, or simple flex is so smart to not add again in the same stack same function for examples: var t:CServiceObj = _rModel.userGetBoardJoined(); t.addEventListener(EDataService.DATA_AVAILABLE,onDataOk); t.addEventListener(EDataService.DATA_AVAILABLE,onDataOk); t.addEventListener(EDataService.DATA_AVAILABLE,onDataOk); thanks

  • Custom UIToolBar from Images

    - by Sophtware
    I need to create a UIToolbar object that uses an image for the background. Most of the buttons are images as well, and rectangular. One button, however, is round and overlaps the toolbar like the Start button on the Windows task bar. See below. I know that I will need to subclass the UIToolbar to paint the image for the toolbar -- I think. If so, does anyone have example code showing how to do this? Furthermore, does anyone have any ideas on how to implement the larger round button? I'm thinking of another custom subclass for this, but not sure if there might be an easier way. I can have the art guys chop the image anyway needed, which I'm sure the round button will need to be chopped some how. Any ideas or sample code?

  • Oracle, slow performance when using sub select

    - by Wyass
    I have a view that is very slow if you fetch all rows. But if I select a subset (providing an ID in the where clause) the performance is very good. I cannot hardcode the ID so I create a sub select to get the ID from another table. The sub select only returns one ID. Now the performance is very slow and it seems like Oracle is evaluating the whole view before using the where clause. Can I somehow help Oracle so SQL 2 and 3 have the same performance? I’m using Oracle 10g 1 slow select * from ci.my_slow_view 2 fast select * from ci.my_slow_view where id = 1; 3 slow select * from ci.my_slow_view where id in (select id from active_ids)

  • [Linq to SQL] Multiple foreign keys to the same table

    - by cdonner
    I have a reference table with all sorts of controlled value lookup data for gender, address type, contact type, etc. Many tables have multiple foreign keys to this reference table I also have many-to-many association tables that have two foreign keys to the same table. Unfortunately, when these tables are pulled into a Linq model and the DBML is generated, SQLMetal does not look at the names of the foreign key columns, or the names of the constraints, but only at the target table. So I end up with members called Reference1, Reference2, ... not very maintenance-friendly. Example: <Association Name="tb_reference_tb_account" Member="tb_reference" <====== ThisKey="shipping_preference_type_id" OtherKey="id" Type="tb_reference" IsForeignKey="true" /> <Association Name="tb_reference_tb_account1" Member="tb_reference1" <====== ThisKey="status_type_id" OtherKey="id" Type="tb_reference" IsForeignKey="true" /> I can go into the DBML and manually change the member names, of course, but this would mean I can no longer round-trip my database schema. This is not an option at the current stage of the model, which is still evolving. Splitting the reference table into n individual tables is also not desirable. I can probably write a script that runs against the XML after each generation and replaces the member name with something derived from ThisKey (since I adhere to a naming convention for these types of keys). Has anybody found a better solution to this problem?

  • finding specific immediate children of an element using prototype

    - by tatilans
    Following DOM structure: <ul> <li class="item">yes</li> <li>no</li> <li class="item">yes</li> <li> <ul> <li class="item">no</li> </ul> </li> </ul> Assuming I have the outer <ul> in $ul. How do I get the two immediate children which have the item-class? In jQuery I would write something like this: $ul.children().filter(".item") $ul.children(".item") $ul.find("> .item") How do I to this with Prototype? I tried the following ... $ul.select("> .item") //WRONG ... but it does does exactly the opposite and returns the one inner <li>

  • System.Security.VerificationException: Operation could destabilize the runtime

    - by Rigobert Song
    I have a web service which is queried using linq to sql but returns an array of objects. I keep getting the following error: System.Security.VerificationException: Operation could destabilize the runtime When I run a method that uses a linq statement to return an array I get this error, but only on my test server, which is windows server 2008. Everything works fine in my win 7 machine. The project is a .net 3.5. Any ideas what the problem might be? Thanks UPDATE: My linq queries return IQueryable.

  • Asp.Net MVC - Blank model not returning blank data

    - by Pino
    I have a form which a user can fill in x times with the data they want too. The form is posted to the following Action. [HttpPost] public ActionResult Manage(ProductOptionModel DataToAdd) { if (!ModelState.IsValid) { return View(DataToAdd); } var ProdServ = new ProductService(); if (DataToAdd.ID != 0) { //Edit Mode. DataToAdd = ProdServ.EditProductOption(DataToAdd); ViewData["Message"] = "Option Changes Made"; }else { //Add DataToAdd = ProdServ.AddProductOption(DataToAdd); ViewData["Message"] = "New Option Added"; } var RetModel = new ProductOptionModel() {ProductID = DataToAdd.ProductID}; return View(RetModel); } So at the bottom I blank the model (Leaving just the required field) and then return to the view. However the view holds the data from the previously submitted form. Any ideas why? I have debugged the code and checked that the RetModel variable is empty.

  • Garage Sale Code &ndash; Everything must go!

    - by mbcrump
    Garage Sale Code     The term “Garage Sale Code” came from a post by Scott Hanselman. He defines Garage Sale Code as: Complete – It’s a whole library or application. Concise – It does one discrete thing. Clear – It’ll work when you get it. Cheap – It’s free or < 25 cents. (Quite Possibly) Crap – As with a Garage Sale, you’ll never know until you get it home if it’s useless. With the code I’ve posted here, you’ll get all 5 of those things (with an emphasis on crap). All of the projects listed below are available on CodePlex with full source code and executables (for those that just want to run it).  I plan on keeping this page updated when I complete projects that benefit the community.  You can always find this page again by swinging by http://garagesale.michaelcrump.net or you can keep on driving and find another sale.
