• Lookup function not working (RS SP2)

  - by Al Reyes

  Hi, I made the upgrade to SP2. I'm trying to use the Lookup function to link data from two different servers. I'm trying first a simple exercise linking data from two datasets from the same server, having one dataset with journals and the other with the account description. My Expression looks like this at a field on the table I have: =Lookup(Fields!ACTINDX.Value,Fields!ACTINDX.Value,Fields!ACTDESCR.Value,"ACCTINFO") I made sure of the names and using only uppercases for datasets and fields but I'm receiving the following message when I try to preview: "An error occurred during local report processing. The definition of the report '/DETAIL' is invalid. The Value expression for the text box 'ACTINDX' refers to the field 'ACTDESCR'. Report item expressions can only refer to fields within the current dataset scope or, if inside an aggregate, the specified dataset scope". I'll appreciate any suggestions. Regards, Al

• Custom object based on database table

  - by Archangel

  Suppose that I have a database query which looks like below - select name, gender, birthday from person where person_id = 1; When this query is executed, some records from the database are returned. I want to make a custom object which will contain the exact attributes as the column names, with the corresponding values. As an example, suppose that the object is X. So it will have three attributes which are X.name, X.gender and X.birthday, with the corresponding values from the records. Is it doable in PHP? If so, then how?

• Has Google introduced a system that allows multiple "keyword-only" domains per site?

  - by tags2k

  I've been told by a client that "a friend" told them that as of January 2010, Google allows multiple domain names that have keywords in them to be associated with a single site. To be honest this sounds rather April-foolish but I'm not sure when his "friend" told him so for the time being I have to take it at face value. I've heard nothing of this and have searched for such a thing this morning, to find nothing but warnings against this practice. Said client seems keen on buying up lots of domains today, so before he insists upon it I just want to be absolutely sure - has Google silently introduced such an allowance, or is there something else they introduced earlier this year that he could be getting confused with? Thanks for any light you can shine on this!

• Python - List and Loop in one def

  - by Dunwitch

  I'm trying to get the def wfsc_pod1 and wfsc_ip into the same def. I'm not quite sure how to approach the problem. I want wfsc_pod1 to display all the information for name, subnet and gateway. Then wfsc_ip shows the ip addresses below it. I also get a None value when I run it as it. Not sure why. Anything more pythonic is more appreciated. class OutageAddress: subnet = ["255.255.255.0", "255.255.255.1"] # Gateway order is matched with names gateway = ["192.168.1.1", "192.168.1.2", "192.168.1.3", "192.168.1.4", "192.168.1.5", "192.168.1.6", "192.168.1.7", "192.168.1.8", "192.168.1.9"] name = ["LOC1", "LOC2", "LOC3", "LOC4", "LOC5", "LOC6", "LOC7", "LOC8", "LOC9"] def wfsc_pod1(self): wfsc_1 = "%s\t %s\t %s\t" % (network.name[0],network.subnet[0],network.gateway[0]) return wfsc_1 def wfsc_ip(self): for ip in range(100,110): ip = "192.168.1."+str(ip) print ip network = OutageAddress() print network.wfsc_pod1() print network.wfsc_ip()

• Compute column widths in a HTML-like manner (based on cell contents)

  - by cipak

  Hi, I have a grid of data that I want to export to RTF, PDF etc. using various (and not perfect) PHP converters/generators. What I am missing most is the HTML table automatic adjustment of column widths based on the lengths of strings in the cells (strings contain line breaks which complicate things a bit, as they should be preserved). I need an algorithm that, given the contents of the cells (plain text), a total width of the table and an average width of a character, would return a width for each column. I wouldn't want to reinvent the wheel if something is already available. Of course it can't be perfect if the font is variable width, but an approximation would do just fine. Or maybe it could have a configurable table with widths for each character. Any hint would be appreciated. Thank you.

• How to extend abstract Entity class in RIA Services

  - by Calanus

  I want to add a bool variable and property to the base Entity class in my RIA services project so that it is available throughout all the entity objects but seem unable to work out how to do this. I know that adding properties to actual entities themselves is easy using .shared.cs and partial classes but adding such properties to the Entity class using similar methods doesn't work. For example, the following code doesn't work namespace System.ServiceModel.DomainServices.Client { public abstract partial class Entity { private bool auditRequired; public bool AuditRequired { get { return auditRequired; } set { auditRequired = value; } } } } All that happens is that the existing Entity class gets totally overriden rather than extending the Entity class. How do I extend the base Entity class so that functionality is available thoughout all derived entity classes?

• How to get the list of files in a directory in a shell script?

  - by jrharshath

  Hi, I'm trying to get the contents of a directory using shell script. My script is: for entry in `ls $search_dir`; do echo $entry done where $search_dir is a relative path. However, $search_dir contains many files with whitespaces in their names. In that case, this script does not run as expected. I know I could use for entry in *, but that would only work for my current directory. I know I can change to that directory, use for entry in * then change back, but my particular situation prevents me from doing that. I have two relative paths $search_dir and $work_dir, and I have to work on both simultaneously, reading them creating/deleting files in them etc. So what do I do now? PS: I use bash.

• Count down timer

  - by Ohmnastrum

  I have a timer set up and it gets called when ever the player is in their turn phase. I also have a multiplier that decrements slowly while the player is committing actions. for some odd reason my mult variable is returning garbage values I initialized it to 1 in the onLoad statement but it still seems to have trouble. -(void) Timerbar:(NSTimer *)barTimer { if(!waitForPlayer) { [barTimer invalidate]; } if(mult > 0.0) { mult -= 0.01; if(mult < 0) { mult = 0; } } power = (mult * 10) / pwrBarMaxWidth; pwrBarWidth = (int)power % limit; NSLog(@"%d", mult); } Do I have a syntax error somewhere?

• C# - implementing GetEnumerator() for a collection inherited from List<string>

  - by Vojtech

  Hi, I am trying to implement FilePathCollection. Its items would be simple file names (without a path - such as "image.jpg"). Once the collection is used via foreach cycle, it should return the full path created by concatenating with "baseDirectory". How can I do that? public class FilePathCollection : List<string> { string baseDirectory; public FileCollection(string baseDirectory) { this.baseDirectory = baseDirectory; } new public System.Collections.IEnumerator GetEnumerator() { foreach (string value in this._list) //this does not work because _list is private yield return baseDirectory + value; } } Thanks in advance! :-)

• Trouble compiling some decompiled C# code

  - by Colin O'Dell

  I was decompiling an open-source project (because the source for the latest version hasn't been released yet). Using RedGate's Reflector tool, it gave me this block of code: if(somecondition == true) { ref Vector3i vectoriRef; float num17 = length - num; Vector3i end = vectori3; (vectoriRef = (Vector3i) &end)[1] = vectoriRef[1] - ((int) num17); } somecondition is a boolean. length and num are floats defined outside the code. vectori3 is also defined outside the code and is of type Vector3i. The type Vector3i is essentially this code, but with x, y, and z stored as integers. When I try to compile this decompiled code, I get the following errors: Line 2: Only assignment, call, increment, decrement, and new object expressions can be used as a statement Line 3: ; expected Line 3: Invalid expression term 'ref' Line 6: 'Vector3i' is a 'type' but is used like a 'variable' Any thoughts on how I can fix this code so it compiles correctly and does whatever it was intended to do?

• Stopping looping thread in Java

  - by halfwarp

  I'm using a thread that is continuously reading from a queue. Something like: public void run() { Object obj; while(true) { synchronized(objectsQueue) { if(objectesQueue.isEmpty()) { try { objectesQueue.wait(); } catch (InterruptedException e) { e.printStackTrace(); } obj = objectesQueue.poll(); } } // Do something with the Object obj } } What is the best way to stop this thread? I see two options: 1 - Since Thread.stop() is deprecated, I can implement a stopThisThread() method that uses a n atomic check-condition variable. 2 - Send a Death Event object or something like that to the queue. When the thread fetches a death event it exists. I prefer the 1st way, however, I don't know when to call the stopThisThread() method, as something might be on it's way to the queue and the stop signal can arrive first (not desirable). Any suggestions?

• Getting a unix timestamp as a string in C++

  - by wyatt

  I'm using the function time() in order to get a timestamp in C++, but, after doing so, I need to convert it to a string. I can't use ctime, as I need the timestamp itself (in its 10 character format). Trouble is, I have no idea what form a time_t variable takes, so I don't know what I'm converting it from. cout handles it, so it must be a string of some description, but I have no idea what. If anyone could help me with this it'd be much appreciated, I'm completely stumped. Alternately, can you provide the output of ctime to a MySQL datetime field and have it interpreted correctly? I'd still appreciate an answer to the first part of my question for understanding's sake, but this would solve my problem.

• How does compiler use lib file ?

  - by Xinus

  I am curious about how c/c++ compiler analyse lib files ? I mean say I create a library containing some classes, I am using that library in my main program. How does compiler know what class names are there in that library. Of course that information is present in binary format, I want to use that functionality in my program, to be specific I have a binary lib file and I want to know all classes and properties/functions present in that lib file. Is it possible ? If compiler can do that why can't some library ? thanks for any clue

• Specify test method name prefix for test suite in junit 3

  - by Marko Kocic

  Is it possible to tell JUnit 3 to use additional method name prefix when looking up test method names? The goal is to have additional tests running locally that should not be run on continuous integration server. CI server doesn't use test suites, it look up for all classes which name ends with "Test" and execute all methods that begins with "test". The goal is to be able to locally run not only tests run by integration server, but also tests which method name starts with, for example "nocitest" or something like that. I don't mind having to organize tests into tests suite locally, since CI is just ignoring them.

• size of an image

  - by Mike

  From times to times I have to know the width and height of images. I am using the following code: UIImage *imageU = [UIImage imageWithContentsOfFile:[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"myImage.png"]]; CGFloat imageW = CGImageGetWidth(imageU.CGImage); CGFloat imageH = CGImageGetHeight(imageU.CGImage); My question is that if it is there any other way to know the width and height of an image, in pixels, without having to load the image on a variable, that's probably consuming memory. Can the dimensions be read from the file directly without loading the whole image? thanks.

• What's the Difference Between These Two Ruby Class Initialization Definitions?

  - by michaelmichael

  I'm working through a book on Ruby, and the author used a slightly different form for writing a class initialization definition than he has in previous sections of the book. It looks like this: class Ticket attr_accessor :venue, :date def initialize(venue, date) self.venue = venue self.date = date end end In previous sections of the book, it would've been defined like this: class Ticket attr_accessor :venue, :date def initialize(venue, date) @venue = venue @date = date end end Is there any functional difference between using the setter method, as in the first example, vs. using the instance variable as in the second? They both seem to work. Even mixing them up works: class Ticket attr_accessor :venue, :date def initialize(venue, date) @venue = venue self.date = date end end

• Just an experiment changing the application data path

  - by Arthur

  When I change the Appication Data path in windows xp registry to a network folder I get this error message on the next system startup: "windows cannot load the user's profile but has logged you with the default profile system" The registry keys are: "[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders]" "[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders]" under the names "AppData" and "Local AppData" I dont care if "Windows logins you with the default profile system" but is there a way to disable that message, or change the message timeout form 30 seconds to 0?,or maybe create an script that changes the Application Data path every system startup? P.S. The computer with the shared folder is always on.

• iPhone: Grouping records in multiple UITableView views

  - by Nic Hubbard

  Let me first say, I know how to create sections and group records within a UITableView. What I am wanting to do is something similar to creating a photo album. So, I have all my data objects coming from core data, and, I want to be able to create a custom group, such as "My Trip to Mexico" and "First Birthday". Then, the user should be able to add objects/records into new sections/albums. So, basically the user is creating custom sections with their own custom names, and then choosing what records should go into that section/album. So, I am just wondering what is the best way to do this? I am thinking that I would just create some extra attributes for my core data model. Or, would I create a whole new "Album Section" object, and somehow use that? Point me in the right direction. :)
