• Make SharePoint 2007 List View read-only

  - by FireSnake

  I need to deploy a new List View for the standard List View Web Part in MOSS 2007 via the object model (the list already exists, a new view should be added). I need and want to make this list view read-only. This is because saving changes to the view would corrupt modifications made to Header/Footer. How can I do that via the object model? I looked at the content db, the read-only flag (0x20) is stored with the view and could technically be updated using calls to proc_GetAllWebPartsOnPage and proc_UpdateView[Properties]. NOTE: The database interface and all mentioned stored procs are all documented by Microsoft. Is there ANY way to do that via the object model, because I would strongly prefer that?

• Javascript - Text Input Attributes

  - by bobrusha

  I need to create a form element <input disabled type="text" value="smth" /> which is disabled by default. It enables when onmouseover occures. onmouseover="this.disabled=false;" And is disabled by onmouseout onmouseout="this.disabled=true;" What I need is to check the following. If the <input> is focused then it shouldn't be disabled. And if the form element loses focus it disables. Please help me to complete the events. <input disabled type="text" value="smth" onmouseover="this.disabled=false;" onfocus="???" onblur="???" onmouseout="if(???){this.disabled=true;}" />

• What Java tools/apis to use for decrypting/encrypting

  - by Java_bear

  I am trying to decrypt (and later encrypt) an email message (ebXML). The message contains a Signature element that contains child elements to specify the SignedInfo, SignatureValue and KeyInfo. Also, the message contains an encrypted attachment. Question: What Java tools/apis should be used for decrypting? I would like to find some tool/api that would (automagically) instantiate objects based on whatever is included with the Signature element, so that the data (message) could be easily validated. And the other way around: Creating objects (specifying methods, signature value and keyinfo) and then outputting the xml to go into the message.

• C++11 initialize array with uniform value in constexpr function

  - by marack

  I have a class template which builds a simple array based on the template parameters as one of its members. I need to be able to initialize every element in the array to a single value in one of the constructors. Unfortunately this constructor must be constexpr. The relevant part boils down to: template <typename T, size_t N> class foo { T data[N]; constexpr foo(T val) { // initialize data with N copies of val } }; Using std::fill or a loop is incompatible with the constexpr requirement. Initializing with : data{val} only sets the first element of the array and zero-initializes the remainder. How can this be achieved? I feel like there should be a solution with variadic templates and tuples etc...

• Hibernate + Spring + session + cache

  - by andromeda

  We are using Hibernate with Spring for our Java application. We find out that when a session update something in database other sessions can not see the update. For example user1 get the account balance from database then user2 increase the balance , if user1 get the object another time he see the account balance before updating (seems that session use the value from its cache) but we want to get the updated object with new account balance. User1 use one session during all activity that is different from user2 session. Is any configuration to force to get the updated object from database? or any other help?

• FastObjects.NET(is an OODB from Versant) performence in Real Scenerios?

  - by Lalit

  FastObjects.NET Saves the whole class object(if marked with attribute Persistent) at once in file system(using serilization or similar technology). They are promissing that it is even faster then normal SQL DB approach. My team also thought it is better and faster to save the whole object once instead of each field one by one. Defination of their website: FastObjects .NET 10.0 fully conforms to the Microsoft.NET 2.0 framework. Tightly integrated with Visual Studio 2005, it offers a developer-friendly, object-oriented alternative to a relational database for .NET persistence. I want to have your experiences of using FastObjects in production scenerio? They are promising for Indexing/Transaction/clustoring/replication.

• hash table with chaining method program freezing

  - by Justin Carrey

  I am implementing hash table in C using linked list chaining method. The program compiles but when inserting a string in hash table, the program freezes and gets stuck. The program is below: struct llist{ char *s; struct llist *next; }; struct llist *a[100]; void hinsert(char *str){ int strint, hashinp; strint = 0; hashinp = 0; while(*str){ strint = strint+(*str); } hashinp = (strint%100); if(a[hashinp] == NULL){ struct llist *node; node = (struct llist *)malloc(sizeof(struct llist)); node->s = str; node->next = NULL; a[hashinp] = node; } else{ struct llist *node, *ptr; node = (struct llist *)malloc(sizeof(struct llist)); node->s = str; node->next = NULL; ptr = a[hashinp]; while(ptr->next != NULL){ ptr = ptr->next; } ptr->next = node; } } void hsearch(char *strsrch){ int strint1, hashinp1; strint1 = 0; hashinp1 = 0; while(*strsrch){ strint1 = strint1+(*strsrch); } hashinp1 = (strint1%100); struct llist *ptr1; ptr1 = a[hashinp1]; while(ptr1 != NULL){ if(ptr1->s == strsrch){ cout << "Element Found\n"; break; } else{ ptr1 = ptr1->next; } } if(ptr1 == NULL){ cout << "Element Not Found\n"; } } hinsert() is to insert elements into hash and hsearch is to search an element in the hash. Hash function is written inside hinsert() itself. In the main(), what i am initializing all the elements in a[] to be NULL like this: for(int i = 0;i < 100; i++){ a[i] = NULL; } Help is very much appreciated. Thanks !

• How do you make the script wait for the status of an Ajax get request before continuing?

  - by codeninja

  Basically what I'm doing is checking for the existence of an object, if it's not found, the script will try to load the source file using getScript. I only want to check this once though then return true or false to the function that calls fetch() fetch:function(obj){ ... isReady = false; $.getScript(obj.srcFile,function(){ isReady=true; warn("was able to load object "+key); }); return isReady; } but return kicks in before the script loads =/ later the script is loaded but the function returned false. This is the beauty of asynchronous I suppose... What's the best way to handle this... Maybe I could check again at some other point if the object exists? Or maybe there's a better way to do this where I dont have to potentially lock the browser?

• Refactoring a nested loop

  - by user3517441

  I have the following code which I use a lot of times in the class. for (int i = 0; i < someList.size(); i++) { for (int j = 0; j < someList.size(); j++) { if (i != j) { someList.get(i).sendMessageTo(someList.get(j))); //variable action } } } The purpose of the loop is to make each element in the List to send a message (or perform another action) to every element in the list except itself. Is there any way I can create a helper method so I don't have to repeat the loop code. I want to be able to state the variable action and call the helper method. Thanks.

• Updating a popup window from source page

  - by Blem

  I have a list of people wrapped in a-tags with onclick for opening a popup window. That popup window contains a previous and next button that invoker a function in the parent window to get the previous/next a-tag and execute the onclick for it. nextAnchor.onclick(); This should update the popup window with the new persons info, but it doesn't update. Adding an alert("") right after makes it update. What i found searching is something about having to leaving the session before JavaScript will update the display and they suggested using setTimeout. Problem is i'm calling on a DOM element and i can't send it in to the setTimeout, so i ended up with setTimeout('eval("'+nextAnchor.getAttribute("onClick")+'")',10); So is there another way to make it update or a way of making the setTimeout use the onclick of a DOM element or is this an acceptable solution even though it uses eval?

• Programming terms - field, member, properties (C#)

  - by Petr

  Hi, I was trying to find meaning of this terms but especially due to language barrier I was not able to understand what they are used for. I assume that "field" is variable (object too?) in the class while "property" is just an object that returns specific value and cannot contain methods etc. By "member" I understand any object that is declared on the class level. But these are just my assumptions based on commented code samples where some careful programmers used "property region" etc. I would really appreciate if someone could explain it to me.

• Should I convert data arrays to objects in PHP in a CouchDB/Ajax app?

  - by karlthorwald

  I find myself converting between array and object all the time in PHP application that uses couchDB and Ajax. Of course I am also converting objects to JSON and back (for sometimes couchdb but mostly Ajax), but this is not so much disturbing my workflow. At the present I have php objects that are returned by the CouchDB modules I use and on the other hand I have the old habbit to return arrays like array("error"="not found","data"=$dataObj) from my functions. This leads to a mixed occurence of real php objects and nested arrays and I cast with (object) or (array) if necessary. The worst thing is that I know more or less by heart what a function returns, but not what type (array or object), so I often run into type errors. My plan is now to always cast arrays to objects before returning from a function. Of course this implies a lot of refactoring. Is this the right way to go? What about the conversion overhead? Other ideas or tips?

• ASP.NET - How can I cache user details for the duration of their visit?

  - by rockinthesixstring

  I've built a Repository that gets user details Public Function GetUserByOpenID(ByVal openid As String) As User Implements IUserRepository.GetUserByOpenID Dim user = (From u In dc.Users Where u.OpenID = openid Select u).FirstOrDefault Return user End Function And I'd like to be able to pull those details down IF the user is logged in AND IF the cached data is null. What is the best way to create a User object that contains all of the users details, and persist it across the entire site for the duration of their visit? I Was trying this in my Global.asax, but I'm not really happy using Session variables. I'd rather have a single object with all the details inside. Private Sub BaseGlobal_AcquireRequestState(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.AcquireRequestState If Session("UserName") Is Nothing AndAlso User.Identity.IsAuthenticated Then Dim repo As UrbanNow.Core.IUserRepository = New UrbanNow.Core.UserRepository Dim _user As New UrbanNow.Core.User _user = repo.GetUserByOpenID(User.Identity.Name) Session("UserName") = _user.UserName() Session("UserID") = _user.ID End If End Sub

Thanks :-)

• The data structure of libev watchers

  - by changchang

  Libev uses three data structures to storage different watchers. Heap: for watchers that sorted by time, such as ev_timer and ev_periodic. Linked list: such as ev_io, ev_signal, ev_child and etc. Array: such as ev_prepare, ev_check, ev_async and etc. There is no doubt about that uses heap to store timer watcher. But what is the criteria of selecting linked list and array? The data structure that stores ev_io watchers seems a little complex. It first is an array that with fd as its index and the element in the array is a linked list of ev_io watcher. It is more convenient to allocate space for array if use linked list as element. Is it the reason? Or just because of the insert or remove operation of ev_io is more frequently and the ev_prepare seems more stable? Or any other reasons?

• Animate css attributes: set "bottom" and remove "top"

  - by Slevin

  I'm working on a few animations with jQuery. I have 3-4 elements which should slide in from the top. I defined their positions with css: #element-1 { top:124px; left:0px; right:auto; bottom:auto; } #element-2 { top:230px; left:670px; right:auto; bottom:auto; } #element-3 { top:auto; left:0px; right:auto; bottom:100px; } Then I save their positions initial on pageload, cause i have to manipulate the css value to top: -1000px to hide them and make the "slide in from top" animation possible. var image_margins = []; $('img').each(function() { var obj = $(this), id = obj.attr('id'), mtop = obj.css('top'), mleft = obj.css('left'), mright = obj.css('right'), mbottom = obj.css('bottom'); // save alle margins in array image_margins[id] = {mtop:mtop,mleft:mleft,mright:mright,mbottom:mbottom}; // hide all content elements obj.css({'top':'-1000px'}); }); When the user clicks the animate button, the elements should slide to their saved positions. The problem: i can't remove the top attribute. Some elements only have bottom margins. I tried to set top to auto or '', but it's always 0px in DOM inspector. And bottom don't work if top is set. How can i get rid of the top attribute? $('.button').click(function(){ $('img').each(function() { var image = $(this), id = image.attr('id'), timeout = 0; setTimeout(function() { var mtop, mleft, mright, mbottom; if (image_margins[id].mtop != 'auto') { mtop = image_margins[id].mtop; } else { mtop = ''; } if (image_margins[id].mleft != 'auto') { mleft = image_margins[id].mleft; } else { mleft = ''; } if (image_margins[id].mright != 'auto') { mright = image_margins[id].mright; } else { mright = ''; } if (image_margins[id].mbottom != 'auto') { mbottom = image_margins[id].mbottom; } else { mbottom = ''; } image.animate({'top':mtop,'left':mleft,'right':mright,'bottom':mbottom},500); },timeout); timeout = timeout + 200; }); });

• Singleton wrapper for Context

  - by kpdvx

  I'm considering creating a singleton wrapper for a Context so my model objects, if necessary, can open and read from a database connection. My model objects do not have access to a Context, and I'd like to avoid needing to pass a reference to a Context from object to object. I was planning to place into this singleton a reference to the Context returned by Application.getApplicationContext(). This singleton object would be initialized in my custom Application instance before anything else would need to or have a chance to use it. Can anyone think of a reason to not do this?

• String.split() - matching leading empty String prior to first delimiter?

  - by tehblanx

  I need to be able to split an input String by commas, semi-colons or white-space (or a mix of the three). I would also like to treat multiple consecutive delimiters in the input as a single delimiter. Here's what I have so far: String regex = "[,;\\s]+"; return input.split(regex); This works, except for when the input string starts with one of the delimiter characters, in which case the first element of the result array is an empty String. I do not want my result to have empty Strings, so that something like, ",,,,ZERO; , ;;ONE ,TWO;," returns just a three element array containing the capitalized Strings. Is there a better way to do this than stripping out any leading characters that match my reg-ex prior to invoking String.split? Thanks in advance!

• jQuery: Any way to "refresh" event handlers?

  - by Legend

  I have two divs, one that holds some stuff and the other with all possible stuff. Clicking on one of the divs will transfer items to the other div. The code I came up with is: $("#holder > *").each(function() { $(this).click(function(e) { $(this).remove(); $("#bucket").append(this); }); }); $("#bucket > *").each(function() { $(this).click(function(e) { $(this).remove(); $("#holder").append(this); }); }); This one works perfectly, except that the event handlers need to be refreshed once I append or remove elements. What I mean is, if I first click on an element, it gets added to the other div, but if I click on this element again, nothing happens. I can do this manually but is there a better way to achieve this?

• Get CSS style from PHP

  - by rpSetzer

  I am parsing pages using Simple DOM parser. It is neat, but I would like to get the applied css style for each element. Not only the inline styles, but every style it applies to that element, being it inline, in-page or external. Is there a class that does that? If not, how would you do it? I do not really care about overriding styles, cascade, or browser specific styles. Having all the directly applied styles would suffice.

• Java Util Linked List - how to find next?

  - by drozzy

  When using Java LinkedList how do you find out the element's next or previous relationships? I mean, in a regular linked list I would do something like this: Node node1 = new Node(); Node node2 = new Node(); LinkedList list = new LinkedList(); list.add(node1); list.add(node2); //then my node1 will know who it's next is: assertEquals(node2, node1.next()); But in Java's LinkedList, the data does not seem to be modified. So how do I actually find out who the "next" (or "previous" in the case of doubly-linked lists) element is?
