  • Do people create and use Web Parts connections?

    - by Javaman59
    I've been writing some SharePoint web parts wich connect (as providers and consumers). I've found many difficulties, and (comparatively*) little material from the web, from books, or from microsoft.com, which is quite surprising as Web Parts have been around since 2003. This is making me think that although web part connections look like a first class feature in SharePoint, that in practice few people write connecting web parts, and few SharePoint users use them. Is this the case - that few developers write connecting web parts, and few users use them? *comparitively: A subjective impression. With each specific problem i usually find only a handful of web pages which address it, and as my problems seem to be fundamental ones (such which data type to wrap in an IWebPartRow), I expect a lot more search results.

  • AVD Failed to Load ~ Failed to Parse Properties ~ Mac OSX

    - by C.D. OKeefe
    I'm going to say upfront, please forgive me. I'm a newbie to android development and fairly new to programming. Also on a Mac. You're going to have to talk...real...slow. I can't get an AVD to load. I've tried it from Eclipse and from the Android SDK Manager. Failed multiple times. Received the same error each time, "Failed to parse properties from Users/myname/.android/avd/nameIGaveEmulator/config.ini." I've the forum here and saw that others have had similar problems, but of the answers given, no one came back to say if they worked, and I don't see anyone with a similar problem on a Mac. If the path needs to be "changed" what exactly does that mean and how do I go about doing so?

  • Validate an XML File Against Multiple Schema Definitions

    - by Jon
    I'm trying to validate an XML file against a number of different schemas (apologies for the contrived example): a.xsd b.xsd c.xsd c.xsd in particular imports b.xsd and b.xsd imports a.xsd, using: <xs:include schemaLocation="b.xsd"/> I'm trying to do this via Xerces in the following manner: XMLSchemaFactory xmlSchemaFactory = new XMLSchemaFactory(); Schema schema = xmlSchemaFactory.newSchema(new StreamSource[] { new StreamSource(this.getClass().getResourceAsStream("a.xsd"), "a.xsd"), new StreamSource(this.getClass().getResourceAsStream("b.xsd"), "b.xsd"), new StreamSource(this.getClass().getResourceAsStream("c.xsd"), "c.xsd")}); Validator validator = schema.newValidator(); validator.validate(new StreamSource(new StringReader(xmlContent))); but this is failing to import all three of the schemas correctly resulting in cannot resolve the name 'blah' to a(n) 'group' component. I've validated this successfully using Python, but having real problems with Java 6.0 and Xerces 2.8.1. Can anybody suggest what's going wrong here, or an easier approach to validate my XML documents?

  • Warning as Error - How to rid these

    - by coffeeaddict
    I cannot figure out how to get rid of errors that basically should not be halting my compile in VS 2010 and should not be show stoppers, or at least I will fix them later but I don't want the compile to just error and halt on these kinds of problems. For example I'm getting the following error: Error 1 Warning as Error: XML comment on 'ScrewTurn.Wiki.SearchEngine.Relevance.Finalize(float)' has a paramref tag for 'IsFinalized', but there is no parameter by that name C:\www\Wiki\Screwturn3_0_2_509\SearchEngine\Relevance.cs 60 70 SearchEngine for this code: /// /// Normalizes the relevance after finalization. /// /// The normalization factor. /// If is false ( was not called). public void NormalizeAfterFinalization(float factor) { if(factor < 0) throw new ArgumentOutOfRangeException("factor", "Factor must be greater than or equal to zero"); if(!isFinalized) throw new InvalidOperationException("Normalization can be performed only after finalization"); value = value * factor; } I looked in Tools | Options and I don't see where I can tweak the compiler and tell it not to worry about comment or XHTML based errors.

  • GridView in UpdatePanel adds extra rows when sorting another grid

    - by chopps
    Hey Everyone, I'm a seeing some weird behavior that i have never seen before. I have two grid in separate UpdatePanels. I can page and sort each without any problems. Each grid is set for 10 per page. If the first grid (13 records) is paged to the second page and then i go down to the second grid (14 records) and page to the next page and the first grid adds a bunch of empty rows to the grid so it is full to show 10. There is no data in the rows...just empty rows. Each grid does this on paging and sorting. Ive stepped through the code and the the loading of the other grids never happens so it tells my AJAX is doing something to add the 'phantom' rows to the grid. Any ideas why or ways to debug this?

  • How do Ruby and Python implement their interactive consoles?

    - by sxa
    When implementing the interpreter for my programming language I first thought of a simple console window which allows the user to enter some code which is then executed as a standalone program as a shell. But there are severe problems: If every line of code the user enters is handled as a standalone program, it has to go through the tokenizer and parser and is then just executed by the interpreter - what about functions then? How can the Python/Ruby interactive consoles (IDLE, irb) "share" the code? How is the code entered handled? Example: >> def x: >> print("Blah") >> >> x() Where is the function stored so it can be called at any time again? How can the interactive console take everything entered as obviously one program without executing everything over and over again?

  • Eclipse error: This project needs to migrate WTP metadata

    - by larf311
    We started a Web Project in Eclipse 3.2 a ways back and we've since upgraded to Eclipse 3.4 but now the Project has the error: "This project needs to migrate WTP metadata" We've tried right-clicking and doing the "quick-fix" which is in fact to Migrate WTP Metadata. Unfortunately nothing happens and the error remains. We can delete that error from the Problems and everything works as it should, however, every time we re-import the project from source control, the error re-appears. Any ideas on how to permanently get rid of this error or how to ACTUALLY migrate WTP metadata? UPDATE: Everyone, please vote on the answer that works for you rather than adding your own answer that references a previous person's answer.

  • compile error: The import xxxx cannot be resolved

    - by Zachary
    I am developing a Java project using Eclipse. The project uses another project called engine, which I have added in my project build-path. As I need to call a dabo class, called House, in one of my project class, named Window, I have used the following code as usual: import ee.asus.kernel.House; I got however the following error in compiling time: Exception in thread "main" java.lang.Error: Unresolved compilation problems: The import ee cannot be resolved House cannot be resolved to a type House cannot be resolved to a type House cannot be resolved to a type at main.ee.asus.GUI.FrameWindow.Window.<init>(Window.java:10) at main.ee.asus.GUI.StartApplication.main(StartApplication.java:13) It's worth to point out that my prject and the dabo project use the same directory/packages names. Does anyone have a clue where the error may be?

  • Form still posts back with return false in JS

    - by jiewmeng
    it seems like #frmToDo still posts backs <form id="frmToDo" name="frmToDo"> ... <a id="btnSubmit" href="javascript:document.frmToDo.submit();">Add</a> google.load("jquery", 1); google.load("jqueryui", 1); google.setOnLoadCallback(function() { ... $("#frmToDo").submit(function() { return false; ... why will this happen? might it be because of href="javascript:document.frmToDo.submit(). how can i submit the form with that link (i didnt use <input type="submit" /> because of styling problems, it seems like buttons are harder to style, esp in different browsers) the AJAX way?

  • Passing a Structure containing an array of String and an array of Integer into a C++ DLL

    - by DanJunior
    I'm having problems with marshaling in VB.NET to C++, here's the code : In the C++ DLL : struct APP_PARAM { int numData; LPCSTR *text; int *values; }; int App::StartApp(APP_PARAM params) { for (int i = 0; i < numLines; i++) { OutputDebugString(params.text[i]); } } In VB.NET : <StructLayoutAttribute(LayoutKind.Sequential)> _ Public Structure APP_PARAM Public numData As Integer Public text As System.IntPtr Public values As System.IntPtr End Structure Declare Function StartApp Lib "AppSupport.dll" (ByVal params As APP_PARAM) As Integer Sub Main() Dim params As APP_PARAM params.numData = 3 Dim text As String() = {"A", "B", "C"} Dim textHandle As GCHandle = GCHandle.Alloc(text) params.text = GCHandle.ToIntPtr(textHandle) Dim values As Integer() = {10, 20, 30} Dim valuesHandle As GCHandle = GCHandle.Alloc(values) params.values = GCHandle.ToIntPtr(heightHandle) StartApp(params) textHandle.Free() valuesHandle.Free() End Sub I checked the C++ side, the output from the OutputDebugString is garbage, the text array contains random characters. What is the correct way to do this?

  • TFS no release folder in build folder

    - by brian b
    I have a tfs build that works fine on the client, but when executed on the server, no actual binaries get created. When I go to the folder: \[MyServer]\builds[BuildName], I see BuildLog.txt ErrorsWarningsLog.txt Release.txt I expect to see a big \Release folder full of my dlls, but I get nothing. The error log reports no problems up until we ask the build to copy the binaries to our staging server. If I comment those out, I get no errors. CustomizableOutDir is true, DropLocation is set to something sensible BuildDirectoryPath is set to something sensible But no matter what, I just don't get any dlls built. Our local TFS guy is baffled too. Any suggestions?

  • Creating a program to find longest path

    - by stef89
    Hi everyone, I'm fairly new to programming and I'm having a few problems. Basically I have to make a function that will find the lengths of all the paths through a network diagram. I've been working on this for hours but I can't seem to get anywhere. Using recursion I can navigate through every path but I'm just unsure as to how I should record the lengths of the paths. Any help would be greatly appreciated. Thanks! $dependencies = array("","","","1","3","4,2"); $durations = array("5","3","4","11","9","10"); function tracePath($path,$dependencies,$durations,$returnArray=array()) { if($dependencies[$path] != "") { $currentTaskDependencies = preg_split("/[\s]*[,][\s]*/", $dependencies[$path]); for($i=0;$i<count($currentTaskDependencies);$i++) { tracePath($currentTaskDependencies[$i]-1,$dependencies,$durations,$returnArray[$i]); } } return $returnArray; } tracePath(6,$dependencies,$durations);

  • Implicit declaration when using a function before it is defined in C, why can't the compiler figure this out?

    - by rolls
    As the title says, I know what causes this error but I want to know why the compiler gives it in this circumstance. Eg : main.c void test(){ test1(); } void test1(){ ... } Would give an implicit declaration warning as the compiler would reach the call to test1() before it has read its declaration, I can see the obvious problems with this (not knowing return type etc), but why can't the compiler do a simple pass to get all function declarations, then compile the code removing these errors? It just seems so simple to do and I don't believe I've seen similar warnings in other languages. Does anyone know if there is a specific purpose for this warning in this situation that I am overlooking?

  • UIActivityViewController 101

    - by Anthony Guay
    I'm starting to get familiar with the new iOS 6 way to share: UIActivityViewController (the same as when you share a photo from the native iOS photo app), but I'm experiencing a few problems. First, when I choose to share via email, I can't find a way to set the subject of the email. Second, when I post on twitter, I can't find how to post a URL (except explicitly writing it in a NSString). Before, on iOS 5, I was using MFMailComposeViewController for Mail and SLComposeViewController for Twitter. It worked well. If there's no way to choose the subject with UIActivityViewController, could there be a way that I put my own custom buttons on the ActivityViewController, buttons that will call MFMailComposeViewController and SLComposeViewController when touched? I'm just speculating here. Thanks!

  • Autorelease with elements in a UITableViewCell - memory leak

    - by Shaun Budhram
    In my 'cellForRowAtIndexPath' method for a UITableView delegate, I'm allocating a cell if it doesn't exist, and in this cell, I'm creating a new activity spinner like so: UIActivityIndicatorView *actView = [[[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray ] autorelease]; I'm using Leaks to detect memory leaks in my program, and for some reason, this is coming up as a leak, even though it's autoreleasing. The cell itself is also autoreleasing. Has anyone had experience with autoreleasing variables coming up as leaks in the Leaks instrument, and how to tackle these problems? Also, if it helps, this is the history Leaks is displaying for this memory location. It looks like it at some point gets an additional retain message? This is not being done in my code.

  • Android: make a scrollable custom view

    - by Martyn
    Hey, I've rolled my own custom view and can draw to the screen alright, but what I'd really like to do is set the measuredHeigh of the screen to, say, 1000px and let the user scroll on the Y axis, but I'm having problems doing this. Can anyone help? Here's some code: public class TestScreen extends Activity { CustomDrawableView mCustomDrawableView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mCustomDrawableView = new CustomDrawableView(this); setContentView(mCustomDrawableView); } } and public class CustomDrawableView extends View { public CustomDrawableView(Context context) { super(context); setVerticalScrollBarEnabled(true); setMinimumHeight(1000); } @Override protected void onDraw(Canvas canvas) { canvas.drawLine(...); // more drawing } } I've tried to override scrollTo, scrollBy, awakenScrollBars etc with a call to super but to no avail. Am I missing something silly, or am I making some fundamental mistake? Thank you in advance, Martyn

  • Android Apps Not Showing Up In AVD

    - by Mike
    I recently started messing with Android Apps, but I have had nothing but problems trying to get them into the Virtual Device for testing. For some reason, they never seem to show up in the AVD. It has worked one time, but that's it out of hours spent just trying to test one or two very simple apps. I've redone the AVD setup many, many times, trying different settings and what not to no avail. I've followed multiple guides and tutorials to the letter to get it working, but they just refuse to show up in the list. :( Any insight would be appreciated, thank you.

  • How can I maximally partition a set?

    - by Gregory Higley
    I'm trying to solve one of the Project Euler problems. As a consequence, I need an algorithm that will help me find all possible partitions of a set, in any order. For instance, given the set 2 3 3 5: 2 | 3 3 5 2 | 3 | 3 5 2 | 3 3 | 5 2 | 3 | 3 | 5 2 5 | 3 3 and so on. Pretty much every possible combination of the members of the set. I've searched the net of course, but haven't found much that's directly useful to me, since I speak programmer-ese not advanced-math-ese. Can anyone help me out with this? I can read pretty much any programming language, from BASIC to Haskell, so post in whatever language you wish.

  • A datastructure for Robotic Sort

    - by amit.codename13
    I am trying to solve this problem : https://www.spoj.pl/problems/CERC07S/ I have identified that i need a datastructure in which reversing operations have lesser time complexity. I tried to create one using a doubly linked list, in which (i thought) reversing can be done in O(1) by just changing a value associated with the starting and ending node which indicates the direction of traversing the list. I tried to implement it but got stuck. Maybe the approach is wrong! Are trees applicable here? If yes, how? Any ideas or links are appreciated? Thanks in advance.

  • InnoDB not supported by webhost. What now?

    - by Peter Perhác
    I was developing a small WAMP web application on my laptop, where I have an instance of mySQL running and I chose InnoDB for my DB engine. After several weeks' development I wanted to make it available to the public and found out the database server provided by my web host does not support InnoDB, only MyISAM. The create-and-populate script generated from the innoDB schema on my laptop, when executed against the live database, can manage to create individual TABLES but then runs into problems creating the VIEWs. Are views not supported in MyISAM? I know FOREIGN KEYs are not. That's very much why I made the choice of InnoDB... What are my chances of making my innoDB schema design work with myISAM? Is there any straightforward way of converting the whole schema from one storage engine to the other? Should I look for another web host that does provide a mysql db that supports innoDB?

  • Cannot initialize non-const reference from convertible type

    - by Julien L.
    Hi, I cannot initialize a non-const reference to type T1 from a convertible type T2. However, I can with a const reference. long l; const long long &const_ref = l; // fine long long &ref = l; // error: invalid initialization of reference of // type 'long long int&' from expression of type // 'long int' Most problems I encountered were related to r-values that cannot be assigned to a non-const reference. This is not the case here -- can someone explain? Thanks.

  • Redirected wikipedia request

    - by Le_Coeur
    Hi people, i need to write a program, that can redirect's http://localhost:8080 to en.wikipedia.org, it seems to be easy, but i have some problems(only with wikipedia with another sites works good). I make url to wikipedia: URL url = new URL("http", "en.wikipedia.org", 80, "/wiki"); than URLConnection, extract headers, and when i want connection.getInputStream(), i received message 404 Not Found. So i have tried some hack for host header, because in this way host header is localhost:8080, therefor i have tried to change host header to wikipedia, and it works, but after request in browser http://localhost:8080 wikipedia opens, but url in browser changes to en.wikipedia.org, but i want proceed with localhost :)

  • SOAP: JWSDP Webservice and Axis2 Client?

    - by Sophomore
    Just a plain simple question to which I could'nt find a straight answer... I'm building a SOAP webservice which is supposed to deliver some data to a client. (Actually it's RDF parsed/stripped to XML)... I'd like to use JWSDP which will generate WDSL specification. Are there any downfalls when the client is using axis2 instead of JWSDP? My intention was, that this shouldn't matter, as this is what WSDL is meant for, but I wanted to check before there arise any incompatibilities or problems...

  • How to deal with the limited Linq Support of OData (Open Data Protocol)

    - by user341127
    I have a software, which uses a lot of Linq to SQL. Recently, I want to immigrate to OData (or WCF Data Service) architecture. But I met too many problems in Linq for the Linq support of OData is so limited. I have to modify most of my Linq statements and test them thoroughly again. I am wondering whether there is a system way to solve such a problem instead of my manual work. For example, by an external package. BTW, now I have no confidence to use OData as a kind of architecture. You are appreciated to share your ideas. Thank you in advance, Ying

  • GridView and multiple postbacks problem

    - by Jonn
    I have a grid view containing checkboxes and a great deal of problems surrounding it. First of all the page on_load and on_init gets called twice. The first call says it's a postback and the second isn't. If I check for postbacks, during the second call the change of state (i.e. A button_click event that was supposed to refresh the data in the grid) that triggered during the first call does not register. If I don't check for postbacks, checkboxes in the GridView do not retain its state by the second call to OnLoad/OnInit.
