• MDX Current Month Problem

  - by schone

  Hi all, I have the following MDX query: WITH MEMBER [Measures].[TY Sales] AS 'SUM([Measures].[Sales])' MEMBER [Measures].[YTD Sales] AS 'SUM(PERIODSTODATE([Time.Fiscals].[2009], [Time.Fiscals].CurrentMember), [Measures].[Sales])' MEMBER [Measures].[LY Sales] AS 'SUM(PARALLELPERIOD([Time.Fiscals].[2009].[8], 1, [Time.Fiscals].CurrentMember),[Measures].[Sales])' MEMBER [Measures].[LYTD Sales] AS 'SUM(PERIODSTODATE([Time.Fiscals].[2009], PARALLELPERIOD([Time.Fiscals].[2009].[8], 1, [Time.Fiscals].CurrentMember)), [Measures].[Sales])' SELECT {[Measures].[TY Sales],[Measures].[YTD Sales],[Measures].[LY Sales],[Measures].[LYTD Sales]} ON COLUMNS, [Time.Fiscals].[2009].[8] ON ROWS FROM [Sales] The above query displays sales for fiscal year 2009 and fiscal month 8 (Feb), I would like the fiscal year and fiscal month dynamic but I'm unsure on how to do this?

• VIrtual class problem

  - by ugur

  What i think about virtual class is, if a derived class has a public base, let's say, class base, then a pointer to derived can be assigned to a variable of type pointer to base without use of any explicit type conversion. But what if, we are inside of base class then how can we call derived class's functions. I will give an example: class Graph{ public: Graph(string); virtual bool addEdge(string,string); } class Direct:public Graph{ public: Direct(string); bool addEdge(string,string); } Direct::Direct(string filename):Graph(filename){}; When i call constructor of Direct class then it calls Graph. Now lets think Graph function calls addedge. Graph(string str){ addedge(str,str); } When it calls addedge, even if the function is virtual, it calls Graph::edge. What i want is, to call Direct::addedge. How can it be done?

• appcfg.py upload_data entity kind problem

  - by Dingo

  Hi, I am developing application on app-engine-path and I would like to upload some data to datastore. For example I have a model models/places.py: class Place(db.Model): name = db.StringProperty() longitude = db.FloatProperty() latitude = db.FloatProperty() If I save this in view, kind() of this entity is "models_place". All is ok, Place.all() in view work fine. But: If I upload some next row using appcfg.py upload_data, the kind() of this entities is Place. loader.py look like this: import datetime, os, sys from google.appengine.ext import db from google.appengine.tools import bulkloader libs_path = os.path.join("/home/martin/myproject/src/") if libs_path not in sys.path: sys.path.insert(0, libs_path) from models import places class AlbumLoader(bulkloader.Loader): def __init__(self): bulkloader.Loader.__init__(self, 'Place', [('name', lambda x: x.decode('utf-8')), ('longitude', float), ('latitude', float), ]) loaders = [AlbumLoader] and command for uploading: python /usr/local/google_appengine/appcfg.py upload_data --config_file=places_loader.py --kind=models_place --filename=data/places.csv --url=http://localhost:8000/remote_api /home/martin/myproject/src/

• C# - File Encoding Problem.

  - by user301330

  Hello, I'm have a StringBuilder that is writing content to a file. Towards the end of each file, I'm writing the copyright symbol. Oddly, I have noticed that whenever the copyright symbol is written, it is preceeded by a "Â". My code that generates the content of the file looks like this: using (StringWriter stringWriter = new StringWriter()) { stringWriter = GetFileContent(); string targetPath = ConfigurationManager.AppSettings["TargetPath"]; using (StreamWriter streamWriter = new StreamWriter(targetPath, false)) { StringBuilder sb = new StringBuilder(stringWriter.ToString()); // Attempted fix string content = sb.ToString(); content = content.Replace("Â", ""); streamWriter.Write(content); } } As you can tell, I tried to do a find-and-replace. In the process, I noticed that a "Â" was not in the content itself. This makes me believe there is something occurring in the streamWriter. However, I'm not sure what it could be. Can someone please tell me why a "Â" would be popping up before the "©" symbol and how to fix it? I believe it has something to do with encoding, but I'm not sure Thank you!

• FireBug - inspect element problem -- showing different interface?

  - by Susan

  When I used to use Firebugs inspect elements feature it displayed the results like this below. Nice, nested tags on the left...css style on the right. Recently, however, when I try to inspect elements it always shows this: I've tried reverting to older versions of FireBug (can't remember if it started after an update?).. I've poked around the settings... Can't find why it's different. The interface it's showing now is completely useless for figuring out what's going on in the html / css.

• problem with null column

  One column in my database (of type double) has some null values. I am executing a sored procedure to get the data in my app wipDBTableAdapters.XLSFacturiTableAdapter TAFacturi = new wipDBTableAdapters.XLSFacturiTableAdapter(); var dtfacturi = TAFacturi.GetData(CodProiect); Then i try to do something like this: if (dtfacturi[i].CANTITATE == null) { //do something } this is giving a warning : The result of the expression is always 'false' since a value of type 'double' is never equal to 'null' of type 'double? However when i run my code i get the following exception: StrongTypingException The value for column 'CANTITATE' in table 'XLSFacturi' is DBNull. How am I supposed to resolve this ?

• How do I use Zend Cache on this particular problem

  - by davykiash

  I have an action that renders two different view scripts based on whether the user is logged in or not. class IndexController extends Zend_Controller_Action { .... public function indexAction() { $auth = Zend_Auth::getInstance(); if($auth->hasIdentity()) { $this->render('indexregistered'); return; } else { $this->render('indexpublic'); return; } } .... } I have seen quite some useful examples on how to use the Zend Cache and they seem to be based on the fact that the action renders one particular script. What am really looking at is the best approach to cache the the indexpublic script does get quite some hits and I would live to avoid the Zend MVC overhead if possible.

• Zend Sessions problem with IE8

  - by Emil

  I'm running a Zend Framework powered website and it seems to have serious problems with sessions. I have a 5 step process where I save the form data in the session between the steps and then save it into the database on the last step. When we built the site sometimes the session just went away and forced us to restart. Now it seems to work again but recently we discovered an issue with Internet Explorer 8. It fails between step 2 - 3 and forgets the session. It works fine in IE6, IE7, FF, Chrome, Safari and even in my mobile web browser (SE P1). We're storing our sessions in the database and if I deactivate the session db handler it works. What's the difference between using the database and not using it for sessions? Do I loose something if I switch back? Bootstrap: /* Start session */ $saveHandler = new Zend_Session_SaveHandler_DbTable(array( 'name' => 'sessions', 'primary' => 'id', 'modifiedColumn' => 'modified', 'dataColumn' => 'data', 'lifetimeColumn' => 'lifetime' )); Zend_Session::rememberMe((int) $config->session->lifetime); $saveHandler->setLifetime((int) $config->session->lifetime) ->setOverrideLifetime(true); Zend_Session::setSaveHandler($saveHandler); Zend_Session::start(); and in my step controller $session = new Zend_Session_Namespace('wizard'); Then I'm just working with $session saving data in a stdClass in $session.

• XQuery - problem with recursive function

  Hi all, Im new on this project and am going to write, what i thought was a simple thing. A recursive function that writes nested xml elements in x levels (denoted by a variable). So far I have come up with this, but keeps getting a compile error. Please note that i have to generate new xml , not query existing xml: xquery version "1.0"; declare function local:PrintTest($amount) { <test> { let $counter := 0 if ($counter <= $amount ) then local:PrintTest($counter) else return $counter := $counter +1 } </test> }; local:PrintPerson(3) My error is: File Untitled1.xquery: XQuery transformation failed XQuery Execution Error! Unexpected token - " ($counter <= $amount ) t" I never understood xquery, and cant quite see why this is not working (is it just me or are there amazingly few resources on the Internet concerning XQuery?)

• strange Problem with WPF Textbox stringformat - Cursor moves back

  - by Emad

  I am using WPF 4.0 TextBox and binding. I am using StringFormat to format the number as currency. the XAML looks like this: <TextBox Text="{Binding Path=ValueProperty, ValidatesOnDataErrors=True, ValidatesOnExceptions=True, StringFormat={}{0:C}, UpdateSourceTrigger=PropertyChanged}"> </TextBox> Everything seems to work correctly except for a strange behavior: When for example a user types in 12: right after typing 1, the value in the textbox becomes $1.00 and the weird thing is the the cursor is moved to be between the $ and the 1. So when a user simply types in 12, the result becomes $21.00. How can I fix this strange behavior?
