• How to update a sharepoint list item via web services using a where clause?

  - by JL

  I would like to update a list item using SharePoint and am stuggling to find 1 decent CAML example. Here is what I want to do, in SQL my query would look something like this update [table] set field='value' where fieldID = id; so this would mean I have 1 item in a list I would like to update 1 field on given the ID of that listitem. I've tried this, but it doesn't work: batchElement.InnerXml = "<Method ID='1' Cmd='Update'>" + "<Field Name='DeliveryStatus'>" + newStatus.ToString() + "</Field>" + "<Where><Eq><FieldRef Name='ID' /><Value Type='Text'>" + id + "</Value></Eq></Where></Method>";

• An analog of String.Join(string, string[]) for List<T> or other generic enumerable

  - by abatishchev

  class String contains very useful method - String.Join(string, string[]). It creates a string from an array, separating each element of array with a symbol given. But general - it doesn't add a separator after the last element! I uses it for ASP.NET coding for separating with "<br />" or Environment.NewLine. So I want to add an empty row after each row in asp:Table. What method of IEnumerable<TableRow> can I use for the same functionality?

• Problem separating C++ code in header, inline functions and code.

  - by YuppieNetworking

  Hello all, I have the simplest code that I want to separate in three files: Header file: class and struct declarations. No implementations at all. Inline functions file: implementation of inline methods in header. Code file: normal C++ code for more complicated implementations. When I was about to implement an operator[] method, I couldn't manage to compile it. Here is a minimal example that shows the same problem: Header (myclass.h): #ifndef _MYCLASS_H_ #define _MYCLASS_H_ class MyClass { public: MyClass(const int n); virtual ~MyClass(); double& operator[](const int i); double operator[](const int i) const; void someBigMethod(); private: double* arr; }; #endif /* _MYCLASS_H_ */ Inline functions (myclass-inl.h): #include "myclass.h" inline double& MyClass::operator[](const int i) { return arr[i]; } inline double MyClass::operator[](const int i) const { return arr[i]; } Code (myclass.cpp): #include "myclass.h" #include "myclass-inl.h" #include <iostream> inline MyClass::MyClass(const int n) { arr = new double[n]; } inline MyClass::~MyClass() { delete[] arr; } void MyClass::someBigMethod() { std::cout << "Hello big method that is not inlined" << std::endl; } And finally, a main to test it all: #include "myclass.h" #include <iostream> using namespace std; int main(int argc, char *argv[]) { MyClass m(123); double x = m[1]; m[1] = 1234; cout << "m[1]=" << m[1] << endl; x = x + 1; return 0; } void nothing() { cout << "hello world" << endl; } When I compile it, it says: main.cpp:(.text+0x1b): undefined reference to 'MyClass::MyClass(int)' main.cpp:(.text+0x2f): undefined reference to 'MyClass::operator[](int)' main.cpp:(.text+0x49): undefined reference to 'MyClass::operator[](int)' main.cpp:(.text+0x65): undefined reference to 'MyClass::operator[](int)' However, when I move the main method to the MyClass.cpp file, it works. Could you guys help me spot the problem? Thank you.

• Is there a more efficient way to retrieve tables from websites using wpf + webclient

  - by Jordan Brooker

  new to the community, but here is my first question that I am stuck on. I am new to WPF and WebClient using c# and I am attempting to make a program that access www.nba.com to populate a combobox I have with team names, and then when a user selects a team from the combobox, I wanted to populate a portion of the main window with the roster from the teams home site, same style and eveything. I was able to populate the combobox using the WebClient.OpenRead and reading in the markup to extract the team names. Now I am on the more difficult part. I was planning on using the same method to grab all the markup and then somehow display the table in a content panel, but I feel that this is a very tedious thing to do. Can anyone give me any tips for completing this action or is there a method in the webclient class that allows me to search a webpage for a table or object other than text? Thanks.

• Customize Annotation problem....Plz Help.. !!

  - by user128647

  I want to show my custom UIView(.Xib View) to appear when user tabbed on pins (not apple's callOutBubble) and in that UIView there should be a button which fires an IBAction on touched down event. Therefore i have added an AddObserver method to MKAnnotationView. which responds to touch events over pin in MKMapView. But i have also added 3 buttons over that XIB view, which have also assined IBActions. But when i run application, Buttons in Customized Annotation view are not responding to IBAction (Touch Down)? Why this happens ?? What is the solution for that??? I need to have called some method, when those 3 buttons tabbed. Thanks

• Design issue with ATG CommercePipelineManager

  - by user1339772

  The definition of runProcess() method in PipelineManager is public PipelineResult runProcess(String pChainId, Object pParam) throws RunProcessException This gives me an impression that ANY object can be passed as the second param. However, ATG OOTB has PipelineManager component referring to CommercePipelineManager class which overrides the runProcess() method and downcast pParam to map and adds siteId to it. Basically, this enforces the client code to send only Map. Thus, if one needs to create a new pipeline chain, has to use map as data structure to pass on the data. Offcourse, one can always get around this by creating a new PipelineManager component, but I was just wondering the thought behind explicitly using map in CommercePipelineManager

• Java: Selected rows's index does not changes when I sort them!

  - by adrian7

  Hello, I have a Jtable on which I called the method table1.setAutoCreateRowSorter(true);. So this works on well. But I also have a methos in my JFrame class which is fired when i push a button. It gets the selected rows indexes using this code int selectedRows[] = this.table1.getSelectedRows();. And displays an edit window for the first row corresponding in the selected interval. The problem is that if I don't click on column's headers (I mean i don't sorte them at all) my method works perfect. But when I sort the row, the indexes of the rows doesn't seems to change at all - thus resulting an edit window for the old row whicn was initially in that position before making any sort. I am using JDK 6 could anyonw give ma a tip?

• C# Async call garbage collection

  - by Troy

  Hello. I am working on a Silverlight/WCF application and of course have numerous async calls throughout the Silverlight program. I was wondering on how is the best way to handle the creation of the client classes and subscribing. Specifically, if I subscribe to an event in a method, after it returns does it fall out of scope? internal MyClass { public void OnMyButtonClicked() { var wcfClient = new WcfClient(); wcfClient.SomeMethodFinished += OnMethodCompleted; wcfClient.SomeMethodAsync(); } private void OnMethodCompleted(object sender, EventArgs args) { //Do something with the result //After this method does the subscription to the event //fall out of scope for garbage collection? } } Will I run into problems if I call the function again and create another subscription? Thanks in advance to anyone who responds.

• Modifying annotation attribute value at runtime in java

  - by Lici

  Hi folks: some methods in our model pojos have been annotated like this: @Column(name="cli_clipping_id", updatable=false, columnDefinition = "varchar(" + ModelUtils.ID_LENGTH + ") COLLATE utf8_bin") columnDefinition attribute is database vendor dependant, so when trying to drop schema in HSQLDB using Hibernate it fails: [ERROR] 16 jun 12:58:42.480 PM main [org.hibernate.tool.hbm2ddl.SchemaExport] Unexpected token: COLLATE in statement [create table cms.edi_editorial_obj (edi_uuid varchar(23) COLLATE ] To fix this, i'm thinking on this solution (but don't want to spend time if it isn't possible) , at runtime, for each method column annotated: Get @Column annotation Create a copy of the column annotation, setting columnDefinition null using javaassist. set column method annotation to the copy column annotation object overriding the old one (i don't know it this is possible) Is it possible to "hack" these methods this way? Any help would be much appreciated ...

• In datastore, confused on how to pass a list of key_names as an argument to somemodel.get_or_insert(

  - by indiehacker

  Are there examples of how to pass a list of key_names to Model.get_or_insert() ? My Problem: With a method of ParentLayer I want to make the children. The key_names of the new (or editable) entities of class Child will come from such a list below: namesList = ["picture1","picture2"] so I should be able to build a list of key_names with method from the parent class as follows: class ParentLayer(db.Model): def getOrMakeChildren(self, namesList): keyslist = [ db.Key.from_path( 'Child' , name , parent = self.key() ) for name in namesList ] the problem is next where I simply want to get_or_insert entities based on keylist defined above: childrenEntitiesList = Child.get_or_insert(keyslist) # no works? also none of the below attempts worked: #childrenEntitiesList = Child.get_or_insert(keyslist, parent = u'TEST') #childrenEntitiesList = Child.get_or_insert(keyslist, parent=self.key().name() ) #childrenEntitiesList = Child.get_or_insert(keyslist, parent=self.key()

• Can't register credit card with Microsoft Windows Azure

  - by user1083268

  I get the following error when trying to sign up for the Microsoft Azure 90-day free trial: We can't authorize the payment method. Please make sure the information is correct, or use another payment method. If you continue to get this message, please contact your financial institution. I've tried three different cards, two credit and one debit. Those cards are issued from two different banks. I've also tried the cards on two separate accounts. Someone from my work also confirmed that he could not sign up for the free trial either. Has anyone else had this problem? I haven't really seen much help searching Google and the support staff doesn't seem interested in helping people sign up for free accounts.

• Java Archtecture Decision !!

  - by santiagobasulto

  Hi everybody! I'm developing a medium Java app, and i'm facing a small problem due to my lack of expirience. I've a custom DAO, which gets "Article" objects from the DataBase. I've the Article class, and the DAO has a method called getArticle(int id), this method returns an Article. The Article has a Category object, and i'm using lazy loading. So, when i request for an Article Category (Article a = new Article(); a.getCategory();) the Article class gets the Category from the DAO and then returns it. I'm now thinking to cache it, so when i request multiple times to an Article's category, the database is only queried one time. My question is: where should i put that cache? I can put it on the Article class (in the DTO), or i can put it on the DAO class. What do you say? Thanks!

• Importing Classes Within a Module

  - by CodeJoust

  Currently, I have a parser with multiple classes that work together. For Instance: TreeParser creates multiple Product and Reactant modules which in turn create multiple Element classes. The TreeParser is called by a render method within the same module, which is called from the importer. Currently, using the class name in the imported module file works only if the file calling the module contains from module_name import *, so the classes are imported into the main namespace. Finally, if the package has dependencies (such as re and another another module within the same folder), where is the best place to require those modules? Within the __init__.py file or within the module itself? I don't really want to add the module name in front of every call to the class, in case I do call import *, however, is it possible to use a variable name of the current module to call the class, or use a workaround in the __init__.py file? I'm probably used to the ruby require '' method instead of python's module system.

• Code optimization - Unused methods

  - by Yochai Timmer

  How can I tell if a method will never be used ? I know that for dll files and libraries you can't really know if someone else (another project) will ever use the code. In general I assume that anything public might be used somewhere else. But what about private methods ? Is it safe to assume that if I don't see an explicit call to that method, it won't be used ? I assume that for private methods it's easier to decide. But is it safe to decide it ONLY for private methods ?

• Operator Overloading with C# Extension Methods

  - by Blinky

  I'm attempting to use extension methods to add an operater overload to the C# StringBuilder class. Specifically, given StringBuilder sb, I'd like sb += "text" to become equivalent to sb.Append("text"); Here's the syntax for creating an extension method for StringBuilder: public static class sbExtensions { public static StringBuilder blah(this StringBuilder sb) { return sb; } } It successfully adds the "blah" extension method to the StringBuilder. Unfortunately, operator overloading does not seem to work: public static class sbExtensions { public static StringBuilder operator +(this StringBuilder sb, string s) { return sb.Append(s); } } Among other issues, the keyword 'this' is not allowed in this context. Are adding operator overloads via extension methods possible? If so, what's the proper way to go about it?

• Android equivalent work-around for View.getX() before API 11?

  - by user48998

  I'm using the getX() and getY() method on a view for some special dragging logic (not animation, i.e. I never use setX/Y methods, I just need the getters to check). However, I've come to realize that these are only available post-API 11. The docs for getX() say that is it the addition of the 'left' property and the 'translationX' property. All well and good, except get/setTranslationX() is only around since API 11 as well. I was wondering if there was any knowledge on what this method returns behind the scenes, so I could maybe put in a workaround. Thanks for any help - Chase

• Using __str__ representation for printing objects in containers in Python

  - by BobDobbs

  I've noticed that when an instance with an overloaded str method is passed to the print() function as an argument, it prints as intended. However, when passing a container that contains one of those instances to print(), it uses the repr method instead. That is to say, print(x) displays the correct string representation of x, and print(x, y) works correctly, but print([x]) or print((x, y)) prints the repr representation instead. First off, why does this happen? Secondly, is there a way to correct that behavior of print() in this circumstance?
