  • Multipage forms for joomla (looking outside the box)

    - by John Snow
    I have created a number of forms using various Joomla components which have more or less worked successfully. Recently I have attempted to create mult-page forms - the forms work...but they are slow as molasses. Having spent a couple of weeks trying to resolve this and not seeing any signs of improvement ...... I wonder if anyone has experience of using hosted forms services in Joomla either using a wrapper or as a static page within a Joomla site. Any pointers or recommendations would be appreciated.

  • Advice on "Invalid Pointer Operation" when using complex records

    - by Xaz
    Env: Delphi 2007 <JustificationI tend to use complex records quite frequently as they offer almost all of the advantages of classes but with much simpler handling.</Justification Anyhoo, one particularly complex record I have just implemented is trashing memory (later leading to an "Invalid Pointer Operation" error). This is an example of the memory trashing code: sSignature := gProfiles.Profile[_stPrimary].Signature.Formatted(True); On the second time i call it i get "Invalid Pointer Operation" It works OK if i call it like this: AProfile := gProfiles.Profile[_stPrimary]; ASignature := AProfile.Signature; sSignature := ASignature.Formatted(True); Background Code: gProfiles: TProfiles; TProfiles = Record private FPrimaryProfileID: Integer; FCachedProfile: TProfile; ... public < much code removed > property Profile[ProfileType: TProfileType]: TProfile Read GetProfile; end; function TProfiles.GetProfile(ProfileType: TProfileType): TProfile; begin case ProfileType of _stPrimary : Result := ProfileByID(FPrimaryProfileID); ... end; end; function TProfiles.ProfileByID(iID: Integer): TProfile; begin <snip> if LoadProfileOfID(iID, FCachedProfile) then begin Result := FCachedProfile; end else ... end; TProfile = Record private ... public ... Signature: TSignature; ... end; TSignature = Record private public PlainTextFormat : string; HTMLFormat : string; // The text to insert into a message when using this profile function Formatted(bHTML: boolean): string; end; function TSignature.Formatted(bHTML: boolean): string; begin if bHTML then result := HTMLFormat else result := PlainTextFormat; < SNIP MUCH CODE > end; OK, so I have a record within a record within a record, which is approaching Inception level confusion and I'm the first to admit is not really a good model. Clearly i am going to have to restructure it. What I would like from you gurus is a better understanding of why it is trashing the memory (something to do with the string object that is created then freed...) so that i can avoid making these kinds of errors in future. Thanks

  • How can I "merge", "flatten" or "pivot" results from a query which returns multiple rows into a sing

    - by dsm
    I have a simple query over a table, which returns results like the following: id id_type id_ref 2702 5 31 2702 16 14 2702 17 3 2702 40 1 2702 26 4 And I would like to merge the results into a single row, for instance: id concatenation 2702 5,16,17,40,26:31,14,3,1,4 Is there any way to do this within a trigger? NB: I know I can use a cursor, but I would really prefer not to unless there is no better way.

  • Breaking out of a nested loop

    - by dotnetdev
    If I have a for loop which is nested within another, how can I efficiently come out of both loops (inner and outer) in the quickest possible way? I don't want to have to use a boolean and then have to say go to another method, but rather just to execute the first line of code after the outer loop. What is a quick and nice way of going about this? Thanks

  • Python function argument scope (Dictionaries v. Strings)

    - by Shaun Meyer
    Hello, given: foo = "foo" def bar(foo): foo = "bar" bar(foo) print foo # foo is still "foo"... foo = {'foo':"foo"} def bar(foo): foo['foo'] = "bar" bar(foo) print foo['foo'] # foo['foo'] is now "bar"? I have a function that has been inadvertently over-writing my function parameters when I pass a dictionary. Is there a clean way to declare my parameters as constant or am I stuck making a copy of the dictionary within the function? Thanks!

    - by timstepp
    Are there any good examples/plugins that enable users to create groups within a community application. For example, I would like to create a Group class and add it to something like Community Engine (http://communityengine.org/). Essentially, users need to be able to create and manage groups that other users can join (much like Facebook Pages). Thanks!

    - by Ohad Regev
    I wish to add some sort of a "Write a Review" or "Rate Us" feature to my app so my customers can easily rate and review my app. Best practice I can think of is to have some sort of pop-up or open a UIWebView within my app so the user is not kicked off of my app while opening the App Store application as done in: [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"itms://itunes.com/apps/myAppName"]]; Does anyone knows of a way to do that?
