• Intercept back button on uinavigationcontroller?

  - by cannyboy

  A form is pushed onto the view. The form has several required fields. Also the form needs to be validated. I want to intercept the back button's click to check if the fields have been filled in, and validate the form. How would I intercept the button's click, and make sure it doesn't pop to the previous screen?

• Setting style of ContextMenu on subitems

  - by thedesertfox

  I have created a custom style and template for MenuItem and ContextMenu, and for my first level, that works great, but whenever I add a SubMenu item, the style of that ContextMenu reverts back to the default style. How can I make sure that item uses my custom style? I've tried using the <;Style TargetType="ContextMenu" Key="{x:Type ContextMenu}" syntax as well, and it doesn't seem to be overriding it either.

  - by superexsl

  Hey, I've got a few loading bars that appear during any postbacks. How can I use CSS to have the cursor change into a custom loading animation? In examples I've come across, I can only turn the cursor into other preset images (such as an hourglass). Is it possible for me to use a custom gif as the cursor? Thanks

• WIX Installing an EXE after Msi install finishes.

  - by Chris

  Hi, I have created an MSI package which when finishes runs an exe. <Package InstallerVersion="200" Compressed="yes" /> <Media Id="1" Cabinet="media1.cab" EmbedCab="yes" /> <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="ProgramFilesFolder"> <Directory Id="INSTALLLOCATION" Name="Installer Example"> <Component Id="VSTOR30.EXE" Guid="4fb0aee7-ec5b-4179-8938-a2be4df8ca0e"> <File Id="VSTOR30.EXE" Source="C:\Projects\InstallationTarget\ExampleInstaller\VSTOR30.EXE" KeyPath="yes" Checksum="yes" /> </Component> </Directory> </Directory> </Directory> <Feature Id="ProductFeature" Title="Installation Target" Level="1"> <ComponentRef Id="VSTOR30.EXE" /> </Feature> <InstallExecuteSequence> <Custom Action="RunEXE" After="InstallFinalize">NOT Installed</Custom> </InstallExecuteSequence> <CustomAction Id="RunEXE" FileKey="VSTOR30.EXE" ExeCommand="[#VSTOR30.EXE]" Execute="immediate" Return="asyncNoWait"> </CustomAction> <UI /> The MSI installs but the EXE is not run. I am calling it after Install Finalize and checking the install sequence in ORCA shows that it is being called at the correct time. I need deploy this through group policy software installation which uses a silent install without inputs. If i use a custom UI and run the EXE in the exit dialog <UI> <UIRef Id="WixUI_Minimal" /> <Publish Dialog="ExitDialog" Control="Finish" Event="DoAction" Value="LaunchApplication">WIXUI_EXITDIALOGOPTIONALCHECKBOX = 1 and NOT Installed</Publish> </UI> <Property Id="WIXUI_EXITDIALOGOPTIONALCHECKBOXTEXT" Value="RunEXE" /> <!-- Step 3: Include the custom action --> <Property Id="WixShellExecTarget" Value="[#VSTOR30.exe]" /> <CustomAction Id="RunEXE" BinaryKey="WixCA" DllEntry="WixShellExec" Impersonate="yes" /> Then i can install the software after the msi has finished running, however when putting this group policy the EXE doesn't install. Is there anything i am missing? Chris

• Optimizing UITableView

  - by Daniel Granger

  I have a UITableview made up with a custom cell loaded from a nib. This custom cell has 9 UILabel s and thats all. When scrolling the table on my iPhone the tables scrolling motion is slightly jerky, its not as smooth as other tableviews! (On the simulator it scrolls fine but I guess its using the extra power of my mac) Are there any tips to help optimize this or any tableview or methods to help find the bottleneck. Many Thanks

• Turn off iPhone/Safari input element rounding

  - by Alex

  My website renders well on the iPhone/Safari browser, with one exception: My text input fields have a weird rounded style which doesn't look good at all with the rest of my website. Is there a way to instruct Safari (via CSS or metadata) not to round the input fields and render them rectangular as intended?

• How to store wiki sites (vcs)

  - by Eugen

  Hello, as a personal project I am trying to write a wiki with the help of django. I'm a beginner when it comes to web development. I am at the (early) point where I need to decide how to store the wiki sites. I have three approaches in mind and would like to know your suggestion. Flat files I considered a flat file approach with a version control system like git or mercurial. Firstly, I would have some example wikis to look at like http://hatta.sheep.art.pl/. Secondly, the vcs would probably deal with editing conflicts and keeping the edit history, so I would not have to reinvent the wheel. And thirdly, I could probably easily clone the wiki repository, so I (or for that matter others) can have an offline copy of the wiki. On the other hand, as far as I know, I can not use django models with flat files. Then, if I wanted to add fields to a wiki site, like a category, I would need to somehow keep a reference to that flat file in order to associate the fields in the database with the flat file. Besides, I don't know if it is a good idea to have all the wiki sites in one repository. I imagine it is more natural to have kind of like a repository per wiki site resp. file. Last but not least, I'm not sure, but I think using flat files would limit my deploying capabilities because web hosts maybe don't allow creating files (I'm thinking, for example, of Google App Engine) Storing in a database By storing the wiki sites in the database I can utilize django models and associate arbitrary fields with the wiki site. I probably would also have an easier life deploying the wiki. But I would not get vcs features like history and conflict resolving per se. I searched for django-extensions to help me and I found django-reversion. However, I do not fully understand if it fit my needs. Does it track model changes like for example if I change the django model file, or does it track the content of the models (which would fit my need). Plus, I do not see if django reversion would help me with edit conflicts. Storing a vcs repository in a database field This would be my ideal solution. It would combine the advantages of both previous approaches without the disadvantages. That is; I would have vcs features but I would save the wiki sites in a database. The problem is: I have no idea how feasible that is. I just imagine saving a wiki site/source together with a git/mercurial repository in a database field. Yet, I somehow doubt database fields work like that. So, I'm open for any other approaches but this is what I came up with. Also, if you're interested, you can find the crappy early test I'm working on here http://github.com/eugenkiss/instantwiki-test

  I have a custom timer that extends android.os.CountDownTimer. I have a test in the test project (standard Android/Eclipse project config) that tests the custom Timer.

Can I not run code that references android code code in junit test?

• Problem with LINQ Generated class and IEnumerable to Excel

  - by mehmet6parmak

  Hi all, I wrote a method which exports values to excel file from an IEnumerable parameter. Method worked fine for my little test class and i was happy till i test my method with a LINQ class. Method: public static void IEnumerableToExcel<T>(IEnumerable<T> data, HttpResponse Response) { Response.Clear(); Response.ContentEncoding = System.Text.Encoding.Default; Response.Charset = "windows-1254"; // set MIME type to be Excel file. Response.ContentType = "application/vnd.ms-excel;charset=windows-1254"; // add a header to response to force download (specifying filename) Response.AddHeader("Content-Disposition", "attachment;filename=\"ResultFile.xls\""); Type typeOfT = typeof(T); List<string> result = new List<string>(); FieldInfo[] fields = typeOfT.GetFields(); foreach (FieldInfo info in fields) { result.Add(info.Name); } Response.Write(String.Join("\t", result.ToArray()) + "\n"); foreach (T t in data) { result.Clear(); foreach (FieldInfo f in fields) result.Add((typeOfT).GetField(f.Name).GetValue(t).ToString()); Response.Write(String.Join("\t", result.ToArray()) + "\n"); } Response.End(); } My Little Test Class: public class Mehmet { public string FirstName; public string LastName; } Two Usage: Success: Mehmet newMehmet = new Mehmet(); newMehmet.FirstName = "Mehmet"; newMehmet.LastName = "Altiparmak"; List<Mehmet> list = new List<Mehmet>(); list.Add(newMehmet); DeveloperUtility.Export.IEnumerableToExcel<Mehmet>(list, Response); Fail: ExtranetDataContext db = new ExtranetDataContext(); DeveloperUtility.Export.IEnumerableToExcel<User>(db.Users, Response); Fail Reason: When the code reaches the code block used to get the fields of the template(T), it can not find any field for the LINQ Generated User class. For my weird class it works fine. Why? Thanks...

• How to insert a DataTable with existing Key to a SQL Server Table.

  - by user296575

  I am working with VB.NET.. i have a DataTable called "QUESTION", containing 3 fields: QuestionNumber (unique integer key) QuestionText QuestionType In my SQL Server database I created a Table called "QUESTION" with the same fields. QuestionNumber is defined as integer unique key, auto increment Now, when i make a bulk copy to insert the DataTable into the SQL Server, the database overwrites my QuestionNumber from the DataTable and generates new ones (starting from 1 increment 1). How do i have to change my database setup, that the original QuestionNumbers are copied into the database?

• Exclude one or more elements from being connected (using connectWith) in jQuery's sortable lists

  - by Lev

  I have two lists, one with an ID of "vlist" and one with an ID of "hlist". The "vlist" holds elements which should be visible, while the "hlist" holds items that should remain hidden. The idea here is to allow the administrator of the system to specify which elements/fields should be shown on a sign-up page, and which shouldn't. The two lists are connected using "connectWith", so the administrator can drag items from the visible list to the hidden list (or vice versa). My dilemma is that there are a few fields I want locked into the visible list, but still sortable within that one list. For example, the "username", "email" and "password" fields should be locked within the visible list (as they always need to be used for registration). Is this even possible? Perhaps it is a no-brainer that I simply haven't discovered yet. I've looked around through jQuery's documentation for a while and can't seem to find anything related to this scenario. I have found how you can "cancel" specific elements in the list from being sortable altogether or even disabled from being a dropable target, but this doesn't do it. The user should still have the ability to drag these items within the "visible" list, in case they want to adjust the ordering of the locked fields. I'm also aware that you can contain sortable elements within a specific element or DOM object, but this also can't be used as this only seems to apply to the whole sortable list, and not specific elements of that list. I've even tried to see if something like this would work after I built the sortable listing(s): $('#vlist > #slist-li-username').sortable('option', 'containment', '#vlist'); Obviously, that didn't work either or I wouldn't be posting this. In case it might help, I thought I'd throw in the code I'm using now; here is the jQuery code: $(function() { $('#vlist, #hlist').sortable ({ connectWith: '.signup-set_flist', forcePlaceholderSize: true, receive: function (event, ui) { var itemID = ui.item.attr('id'); var fID = itemID.replace(/slist-li-/g, ''); var hID = 'slist-' + fID; if (ui.sender.attr('id') == 'vlist') { $('#'+hID).val(''); } else { $('#'+hID).val(fID); } } }).disableSelection(); $('#vlist > #slist-li-username').sortable('option', 'containment', '#vlist'); }); And as for the HTML, I'll upload it to here (since StackOverflow seems to break when I paste it in here - even in code mode): http://sikosoft.net/jquery-sort-connect.html Any help would greatly be appreciated! :) Oh, and be gentle as this is my first question here. ;)
