• How to link to a folder in document library from sharepoint list item?

  - by kyrisu

  Hi, Background: I have an items on the sharepoint list. I also have a corresponding folder in a document library that contains documents about this item. I want to be able to get to this folder straight from the item properties. I have tried to create a lookup column containing folder ID, but that doesn't help cause folder is not a type and it just doesn't work. Other solution would be to create link column but if I will create it staticly - after creating alternative mapping (and getting to the page from the internet for example) it won't work. (so solution posted here won't work for me). I want to create this link from sharepoint workflow. I have a custom action that can return any info about the folder I want (ID, URL etc). Question: How to link from sharepoint list item to a folder in document library?

• WPF Datatemplate + ItemsControl each item uses > 1 MB Memory?

  - by Matt H.

  Does that sound right to anyone???? I have an ItemsControl that displays data from a custom object that implements iNotifyPropertyChanged. The DataTemplate consists of: Border 3 buttons 5 textboxes An ellipse A Bindable RichTextBox (custom class that inherits from RichTextBox... so I could make Document a dependency property (to support binding)) Several grids and stackpanels for layout It uses: Styles (stored in a resource dictionary higher up the tree) Styles affect: colors, thicknesses, and text properties: which are data-bound to a "settings" class that implements iNotifyPropertyChanged, so the user can change display settings That's it! So what gives? I've also noticed that when I empty and remove the ItemsControl, memory isn't freed. over 5000 instances of "CommandBindingCollection" and "WeakReference" are CREATED (using ANTS profiler). And huge number of EffectiveValueEntry objects are created too. So really, what gives!!! :-) Thanks for your insight! Management needs this project soon but in its current state, it's unreleasable.

• When using source control, what files should actually be commited?

  - by SimpleCoder

  I am working on a small project, hosted on Google Code, using SVN for source control. This is my first time using source control, and I'm a bit confused about what I should actually be committing to the repository. My project is very simple: A Class Library project, written in C#. The actual code that I have written is a single file. My question is this: Should I be committing the entire project (including directories like Debug, Release, Properties, etc.) or just my main .cs file? Thanks, After fighting with Subversion for a while (note to self: do not reset repository), it looks like I finally have it working with the directories laid out properly. Thanks again for all your advice.

• visual studio 2005 problem with windows flying open

  - by Kevin

  I'm going through the problem of setting up a new computer and I'm having a problem with VS 2005. Whenever I start debugging all the windows (properties, watch, errorlist, stack, ...) pop up all over the place undocked. At this point I've tried docking them and closing them. When I stop debugging more windows pop up all undocked. This keeps happening over and over and over... I've tried closing and docking them but they keep popping out. Wasn't sure how to google this and my patience has grown thin with this whole process of moving to a new comp. Sincerely, Frustrated

• Elegantly Handle Repetitive Property Code in C#

  - by Eric J.

  The language shortcut public string Code { get; set; } saves a bit of typing when defining trivial properties in C#. However, I find myself writing highly repetitive, not-quite-as-trivial property code that still follows a clear pattern e.g. public string Code { get { return code; } set { if (code != value) { code = value; NotifyPropertyChanged("Code"); } } } I can certainly define a Visual Studio snippet to reduce typing. However, if I need to add something to my pattern, I have to go back and change quite a bit of existing code. Is there a more elegant approach? Is a snippet the best way to go?

• How to test if an array contains a pair of numbers whose product is odd?

  - by John

  How can I write a function that takes an array of integers and returns true if their exists a pair of numbers whose product is odd? What are the properties of odd integers? And of course, how do you write this function in Java? Also, maybe a short explanation of how you went about formulating an algorithm for the actual implementation. Yes, this is a function out of a textbook. No, this is not homework—I'm just trying to learn, so please no "do your own homework comments."

• How can I animate between states in a programmatic skin? [FLEX]

  - by Lewis

  I have a button with the various states (up/over/down etc) that uses a skin file to render the display. I want to achieve animation between the states. For instance, between the change from 'up' to 'over' I want to fade in a color and a border. The way I am doing this at the moment is to use viewstates and animate between them using transitions and the mx:AnimateProperty. However, using this method I can only animate one property per viewstate. So only the border, or the color can be animated. Does anyone know how I can achieve multiple animations on multiple properties of a programmatic button skin? Thanks in advance! Note: I have looked into using tweener but cannot see how it would help my situation

• Inheritance policy when designing the base class

  - by Xaqron

  I have a base class and a derived class both in design phase. The base class will remain one but many derived class will inherit from it. So it's very costly to make change to derived classes in the future and I'm looking for the best design to prevent this. In fact derived class only needs a few methods to override (if needed) but it's tempting to reveal more details to it. My question is about the policy which is extensible in future. Can I minimize the inherited methods/properties to derived class and reveal more in the next versions if needed without any change to derived classes ? Or I should reveal anything that maybe used by derived classes in the future and let them to choose if they need them or not ? Thanks

• Problems using Custom Layout in XML

  - by Kevin

  I've created a new GridLayout class that I want to use in an XML File. The class is in another project. I've created the attrs.xml file in the other project with my properties but when the constructor gets called with the AttributeSet, none of the values are set. In my xml for my screen layout, I refer to the layout with the following: xmlns:gridLayout="@com.mastertechsoftware.AndroidUtil:http://schemas.android.com/apk/res/com.mastertechsoftware.AndroidUtil" Not sure if that is right. I have the attrs.xml file being compiled to R.java in com/mastertechsoftware/AndroidUtil. All the right styleable values are there. In my constructor, I use: TypedArray a = c .obtainStyledAttributes(attrs, R.styleable.GridLayout); this.numRows = a.getInt(R.styleable.GridLayout_numRows, -1); Nothing comes back (-1 does but that means nothing is there) If I use int n = a.getIndexCount(); I get 0.

• AS3 Components in Flash Designer

  - by Jack Voight

  In an ActionScript 2 project I can create a new MovieClip, right-click on it on the library and select "Component Definition" to add parameters that can be referenced inside the MovieClip. This parameters can be easily changed in the MovieClips's properties. Now, I'm working on an ActionScript 3 project but haven't been able to figure out a way to obtain the values passed in those parameters. I defined a parameter named "textToDisplay" but when I write the following in the Actions for the first frame I get an error: trace(textToDisplay); This is the error: 1120: Access of undefined property textToDisplay. Do you know how to capture the value of that parameter? Thanks PS: I'm using Adobe Flash CS3 Professional on Windows XP

• Writing Strings to files in python

  - by Leif Andersen

  I'm getting the following error when trying to write a string to a file in pythion: Traceback (most recent call last): File "export_off.py", line 264, in execute save_off(self.properties.path, context) File "export_off.py", line 244, in save_off primary.write(file) File "export_off.py", line 181, in write variable.write(file) File "export_off.py", line 118, in write file.write(self.value) TypeError: must be bytes or buffer, not str I basically have a string class, which contains a string: class _off_str(object): __slots__ = 'value' def __init__(self, val=""): self.value=val def get_size(self): return SZ_SHORT def write(self,file): file.write(self.value) def __str__(self): return str(self.value) Furthermore, I'm calling that class like this: def write(self, file): for variable in self.variables: variable.write(file) I have no idea what is going on. I've seen other python programs writing strings to files, so why can't this one? Thank you very much for your help.

• C# - Erase all property values from a class?

  - by John M

  In a C# Winforms (3.5) application I have added a class that contains many properties (get/set) used to stored values from a 12 form long process. After form 12 I would like wipe out all the property values in the storing class so that the next user won't accidentally record values when starting the process at form 1. Is it possible to erase/destroy/dispose of all property values in a class? My class looks like this: private static int battery; public int Battery { get { return storeInspectionValues.battery; } set { storeInspectionValues.battery = value; } }

• Is there anything wrong with a class with all static methods?

  - by MatthewMartin

  I'm doing code review and came across a class that uses all static methods. The entrance method takes several arguments and then starts calling the other static methods passing along all or some of the arguments the entrance method received. It isn't like a Math class with largely unrelated utility functions. In my own normal programming, I rarely write methods where Resharper pops and says "this could be a static method", when I do, they tend to be mindless utility methods. Is there anything wrong with this pattern? Is this just a matter of personal choice if the state of a class is held in fields and properties or passed around amongst static methods using arguments?

• Could/Should I use static classes in asp.net/c# for shared data?

  - by death.au

  Here's the situation I have: I'm building an online system to be used by school groups. Only one school can log into the system at any one time, and from that school you'll get about 13 users. They then proceed into a educational application in which they have to co-operate to complete tasks, and from a code point of view, sharing variables all over the place. I was thinking, if I set up a static class with static properties that hold the variables that are required to be shared, this could save me having to store/access the variables in/from a database, as long as the static variables are all properly initialized when the application starts and cleaned up at the end. Of course I would also have to put locks on the get and set methods to make the variables thread safe. Something in the back of my mind is telling me this might be a terrible way of going about things, but I'm not sure exactly why, so if people could give me their thoughts for or against using a static class in this situation, I would be quite appreciative.

• 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?

• WCF server component getting outdated user name

  - by JoelFan

  I am overriding System.IdentityModel.Policy.IAuthorizationPolicy.Evaluate as follows: public bool Evaluate(EvaluationContext evaluationContext,ref object state) { var ids = (IList<IIdentity>)evaluationContext.Properties["Identities"]; var userName = ids[0].Name; // look up "userName" in a database to check for app. permissions } Recently one of the users had her user name changed in Active Directory. She is able to login to her Windows box fine with her new user name, but when she tries to run the client side of our application, the server gets her old user name in the "userName" variable in the code above, which messes up our authentication (since her old user name is no longer in our database). Another piece of info: This only happens when she connects to the server code on the Production server. We have the same server code running on a QA server, and it does not have this issue (the QA server code gets her correct (new) user name) Any ideas what could be going on?

• Adding java source (.java files) to test jar in Maven

  - by user320550

  Hi all, I'm making use of my pom.xml and am was able to generate the jar for src/main/java (say app.jar) as well as for src/test/java (say app-test.jar). I was also able to include my java sources as part of the app.jar (i.e. have both my .class as well as my .java files in the jar). However for my app-test.jar, i'm not able to include my .java files in it. This is my pom.xml: <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.mycompany.app</groupId> <artifactId>my-app</artifactId> <version>1.0-SNAPSHOT</version> <packaging>jar</packaging> <name>my-app</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> </dependencies> <build> <resources> <resource> <directory>src/main/java</directory> </resource> </resources> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <version>2.3.1</version> <executions> <execution> <phase>package</phase> <goals> <goal>test-jar</goal> </goals> <configuration> <includes> <include>src/test/java</include> </includes> </configuration> </execution> </executions> </plugin> </plugins> </build> </project> Any help would be appreciated.

• How to use a class as the base, but hide the class type publically?

  - by James

  I am currently just exposing the properties through a generic interface e.g. public interface IBaseClass { int ID { get; set; } } internal class MyBaseClass : IBaseClass { public MyBaseClass() { } public int ID { get; set; } } public class MyExposedClass : IBaseClass { private MyBaseClass _base = new MyBaseClass(); public int ID { get { return _base.ID; } set { _base.ID = value; } } } Then in my main application I can do: IBaseClass c = new MyExposedClass(); c.ID = 12345; But can't do: MyBaseClass b = new MyBaseClass(); This is my desired behaviour. However, I was just wondering if this is the correct approach? Or if there was a better way?

• databinding to self without code

  - by jcollum

  I'm building a UserControl in WPF. The control has two properties, Title and Description, that I'd like to bind to two textblocks. Seems real straightforward, and I got it working, but I'm curious about something. To get it to work I had to add this code: void CommandBlock_Loaded(object sender, RoutedEventArgs e) { this.DataContext = this; } My bindings look like this: <TextBlock Text="{Binding Title}" Width="100" ... /> <TextBlock Text="{Binding Description}" Width="100" ... /> What I'm wondering is how come I couldn't get it to work without the this.DataContext = this; and instead use DataContext="{Binding RelativeSource={RelativeSource Self}}" (in the UserControl element of the markup)? I'm sure I'm missing something about DataContexts but don't know what.

• Unable to import example projects from book (newbie question)

  I am trying to import projects from a book "Beginning Android 2" but when I choose the root directory the "Finish" button is still grayed out. I've tried importing the project from scratch with no success, and I've also tried to create a template project with the same name and everything and then importing into that (Import existing projects into workspace) but it always says "No projects are found to import". The contents of the folder are: Res folder, src folder with .java file, the manifest, build, and default.properties files. I am new to android dev (obviously) so I appreciate the help.

• Image as a background of a form in Delphi

  - by Averroes

  I'm using Delphi 2006. I have a few PNG images with transparencies and I have to create a GUI using them (top bar, left panel...). The images have different aligns properties. One of the images is the background of the form. The problem here is that I can't align it as alClient because it only occupies the rectangular zone that the other images have left, showing the naked canvas in their transparent zones. What I need is that the background image is put behind all the other images and taking all the canvas size. Is there anyway to do this? I know I can do this writting some logic in the OnResize event of the form but I was just curious if I was missing something. Thanks.

• What's the best way to return different cells depending on position in a UITableView

  - by Robert Conn

  I have a grouped UITableView that has 3 sections and a number of cells in each section that each need to be a different custom cell, with different display requirements. I currently have a large if statement in cellForRowAtIndexPath, with each branch instantiating and returning the appropriate custom cell based on interrogating the indexPath's section and row properties. e.g. if (indexPath.section == 0 && indexPath.row == 0) { // instantiate and return cell A } else if (indexPath.section == 1 && indexPath.row == 2) { // instantiate and return cell B } //etc etc What is best practice for this scenario? A large if statement does the job, but is it the best implementation?

• VB6 debugging- doesn't go to error handling code.

  - by Can Ho

  Hi, I'm maintaining a vb6 project(ActiveX DLL). When debugging, the app run into the following function: Public Function HasValue(ByVal vValue) As Boolean On Error GoTo Err If IsMissing(vValue) Then HasValue = False ElseIf IsNull(vValue) Or Len(vValue) = 0 Then HasValue = False ElseIf isEmpty(vValue) Then HasValue = False Else HasValue = True End If Exit Function Err: If IsArray(vValue) Or IsObject(vValue) Then HasValue = True Else HasValue = False End If End Function and it stops at the line ElseIf IsNull(vValue) Or Len(vValue) = 0 Then vValue is a custom object, contains some properties(obviously, not null). Although I didn't put any break point there, the app stopped there and alerted error dialog saying that "Run-time error '438': Object doesn't support this property or method". We had error handling code but the app didn't run to error handling code. It just stopped at the line causing the error and I had to stop the application. Do you have any idea about that? Thank you very much.
