• Report Builder Error (Input string was not in a correct format) when filtering data

  - by JVZ

  Issue: the user is getting an error “The requested list could not be retrieved because the query is not valid or a connection could not be made to the data source.” while trying to filter a reporting using Report Builder 2.0. When you expand the details the message is “Input string was not in a correct format” I verified that when the user clicks to see the filter values the query is being sent to the underlying database (by using profiler). When I build the same report [I'm a server admin] I have no issues and see all the filtered values, which leads me to believe this is a permissions issue. I believe I granted all the correct permissions, see below: Report Server Setup [Project Name] Data Sources Models […other folders] We are using SQL Server 2005. The user belongs to a poweruser domain group which has the following permissions: Home Report Builder View Folders Browser Home/[Project Name] Browser Report Builder View Folders [Data Sources] Browser Content Developer [Models] [Inherit roles from Parent folder] << should be same as [Project Name] folder Report server log is showing the following: w3wp!library!5!04/21/2010-08:47:27:: Call to GetPermissionsAction(/). w3wp!library!a!04/21/2010-08:47:27:: Call to GetPropertiesAction(/, PathBased). w3wp!library!5!04/21/2010-08:47:27:: Call to GetSystemPermissionsAction(). w3wp!library!a!04/21/2010-08:47:27:: Call to ListChildrenAction(/, False). w3wp!library!a!04/21/2010-08:47:27:: Call to GetSystemPropertiesAction(). w3wp!library!a!04/21/2010-08:47:27:: Call to GetSystemPropertiesAction(). w3wp!library!9!04/21/2010-08:47:40:: Call to ListModelPerspectivesAction(). w3wp!library!9!04/21/2010-08:48:22:: Call to GetUserModelAction(//Models/, ). w3wp!library!5!04/21/2010-08:48:45:: Call to GetItemTypeAction(/). w3wp!library!9!04/21/2010-08:48:46:: Call to GetItemTypeAction(/). w3wp!library!5!04/21/2010-08:48:53:: Call to GetItemTypeAction(/). w3wp!library!a!04/21/2010-08:49:21:: Call to ListModelPerspectivesAction(). w3wp!library!b!04/21/2010-08:53:40:: Call to GetUserModelAction(//Models/, ). w3wp!library!5!04/21/2010-08:54:48:: i INFO: Call to RenderFirst( '' ) w3wp!webserver!5!04/21/2010-08:54:48:: i INFO: Processed report.

• Filtering by date with DataTable.RowFilter while ignoring time

  How do I filter for records on a DataTable which are on a certain date? I've tried plain [datecol] = #11 March 2010# and CONVERT([datecol],'System.DateTime') = #11 March 2010#. With no luck. MSDN: RowFilter Expression Syntax Solution [datecol] >= #11 March 2010 00:00# AND [datecol] <= #11 March 2010 23:59:59#

• Filtering out emoticons using sed

  - by user349222

  Hello, I have a grep expression using cygwin grep on Win. grep -a "\\,,/\|\\m/\|\\m/\\>\.</\\m/\|:u" all_fbs.txt > rockon_fbs.txt Once I identify the emoticon class, however, I want to strip them out of the data. However, the same regexp above within a sed results in a syntax error (yes, I realize I could use /d instead of //g, but this doesn't make a difference, I still get the error.) sed "s/\(\\,,/\|\\m/\|\\m/\\>\.</\\m/\|:u\)*//g" The full line is: grep -a "\\,,/\|\\m/\|\\m/\\>\.</\\m/\|:u" all_fbs.txt | sed "s/\(\\,,/\|\\m/\|\\m/\\>\.</\\m/\|:u\)*//g" | sed "s/^/ROCKON\t/" > rockon_fbs.txt The result is: sed: -e expression #1, char 14: unknown option to `s' I know it's coming from the sed regexp I'm asking about it b/c if I remove that portion of the full line, then I get no error (but, of course, the emoticons are not filtered out). Thanks in advance, Steve

• Filtering most out of XML with XSL?

  - by Gnudiff

  I need to transform a lot of XML files (Fedora export) into a different kind of XML. Trying to do it with XSL stylesheets and checking with the msxsl transformer. Supposedly I have xml file like this (assuming there are actually other nodes inside AAA, OBJ, amd all other nodes), Source.XML: <DOC> <AAA> <STUFF>example</STUFF> <OBJ> <OBJVERS id="A1" CREATED="2008-02-18T13:28:08.245Z"/> <OBJVERS id="A2" CREATED="2008-02-19T10:42:41.965Z"/> <OBJVERS id="A13" CREATED="2009-03-16T12:43:11.703Z"/> </OBJ> </AAA> <FFF/> <GGG/> <DDD> <FILE /> </DDD> </DOC> Which I need to look something like this (Target.XML): <MYOBJ> <ELEM>contents of OBJVERS with the biggest id OR creation date (whichever is easier to do) go here</ELEM> <IMAGE> contents of <FILE> node go here</IMAGE> </MYOBJ> The main problem that I have is that since I am new to XSL (and for this particular task do not have enough time to learn it properly) is that I can't understand how to tell XSL processor not to process anything else, I keep getting output from , for example. Update: basically, I solved this problem meanwhile. I will post my own answer and close the question. Update2: OK, Andrew's answer works, too, so I am just accepting it. :)

• filtering directly and indirectly connected things from list

  - by Andreas Romeyke

  Hello, if you have a function "test a b" which returns true if a and b are connected directly and if you have a given unordered list of things, what would be an elegant and fast solution to filter all connected things from given list? Example: let test a b = let diff = a - b in diff == 0 ;; let lst = [4;1;7;3;8;9;2;0] ;; filter_connected 2 lst ;; - [4;1;3;2;0] Any hints?

• Modify request querystring paramaters to build a new link without resorting to string manipulation

  - by Andrew M

  Hi All, I want to dynamically populate a link with the URI of the current request, but set one specific query string parameter. All other querystring paramaters (if there are any) should be left untouched. And I don't know in advance what they might be. Eg, imagine I want to build a link back to the current page, but with the querystring parameter "valueOfInterest" always set to be "wibble" (I'm doing this from the code-behind of an aspx page, .Net 3.5 in C# FWIW). Eg, a request for either of these two: /somepage.aspx /somepage.aspx?valueOfInterest=sausages would become: /somepage.aspx?valueOfInterest=wibble And most importantly (perhaps) a request for: /somepage.aspx?boring=something /somepage.aspx?boring=something&valueOfInterest=sausages would preserve the boring params to become: /somepage.aspx?boring=something&valueOfInterest=wibble Caveats: I'd like to avoid string manipulation if there's something more elegant in asp.net that is more robust. However if there isn't something more elegant, so be it. I've done (a little) homework: I found a blog post which suggested copying the request into a local HttpRequest object, but that still has a read-only collection for the querystring params. I've also had a look at using a URI object, but that doesn't seem to have a querystring

• Help filtering childs

  - by lidermin

  Hello, I have this jquery code: $(".button-banc").hover(function() { $(".button-banc img") .animate({ top: "-21px" }, 200).animate({ top: "-17px" }, 200) // first jump .animate({ top: "-19px" }, 100).animate({ top: "-17px" }, 100) // second jump .animate({ top: "-18px" }, 100).animate({ top: "-17px" }, 100); // the last jump }); The effect I want is: when you pass the mouse over an image this image should jump a bit. The problem is that I got "some" images with the class "button-banc" and I want this behaive: When you pass the mouse over, "only the actual image" should jump. The problem is that with the code I posted, every image jumps. How can I achieve this, please help; I want to make a generic way, so that if I add images with the class, they also behaive like that. Thanks.

• Filtering custom fields on wordpress admin page

  - by Kyril

  I'm currently working on a wordpress 2.9.2 plugin (my first) that creates additional custom fields that will later be read from the template. The plugin adds an additional meta box to the "Edit Post" screen which is responsible for manipulating these values. My problem is that the custom fields generated by the plugin also show up in the "Custom Fields" box. Ideally I would like for the custom fields generated by the plugin to be managed separately from any other custom fields for that same post/page. Is there a way that I can filter fields specific to my plugin to prevent them from being displayed in the "Custom Fields" box? I have yet to locate any action or filter that will let me capture and manipulate those values before they are rendered on "Edit Post".

• IIS6 cannot start additional processes when page request is called from other than localhost

  - by awe

  I have a web application dll that is running under iis6. This is starting a number of processes to be able to handle more than one request at the time. This is working perfect in a numbers of installations. In this particular installation, it runs perfectly when initialized by a call in IE on the server using http://localhost/apppath . The problem is when the processes are from another location, i.e. another computer on the same network initialising the call throught http://servername/apppath . In this case, the initial dll running under iis is executing (proved by logging), but it fails to initialize the additional processes. If the additional processes are already initialized by a call from localhost, it also works when called from another machine (in this case, it is just attached to the existing processes).

• Building an external list while filtering in LINQ

  - by Khnle

  I have an array of input strings that contains either email addresses or account names in the form of domain\account. I would like to build a List of string that contains only email addresses. If an element in the input array is of the form domain\account, I will perform a lookup in the dictionary. If the key is found in the dictionary, that value is the email address. If not found, that won't get added to the result list. The code below will makes the above description clear: private bool where(string input, Dictionary<string, string> dict) { if (input.Contains("@")) { return true; } else { try { string value = dict[input]; return true; } catch (KeyNotFoundException) { return false; } } } private string select(string input, Dictionary<string, string> dict) { if (input.Contains("@")) { return input; } else { try { string value = dict[input]; return value; } catch (KeyNotFoundException) { return null; } } } public void run() { Dictionary<string, string> dict = new Dictionary<string, string>() { { "gmail\\nameless", "[email protected]"} }; string[] s = { "[email protected]", "gmail\\nameless", "gmail\\unknown" }; var q = s.Where(p => where(p, dict)).Select(p => select(p, dict)); List<string> resultList = q.ToList<string>(); } While the above code works (hope I don't have any typo here), there are 2 problems that I do not like with the above: The code in where() and select() seems to be redundant/repeating. It takes 2 passes. The second pass converts from the query expression to List. So I would like to add to the List resultList directly in the where() method. It seems like I should be able to do so. Here's the code: private bool where(string input, Dictionary<string, string> dict, List<string> resultList) { if (input.Contains("@")) { resultList.Add(input); //note the difference from above return true; } else { try { string value = dict[input]; resultList.Add(value); //note the difference from above return true; } catch (KeyNotFoundException) { return false; } } } The my LINQ expression can be nicely in 1 single statement: List<string> resultList = new List<string>(); s.Where(p => where(p, dict, resultList)); Or var q = s.Where(p => where(p, dict, resultList)); //do nothing with q afterward Which seems like perfect and legal C# LINQ. The result: sometime it works and sometime it doesn't. So why doesn't my code work reliably and how can I make it do so?

• Django and json request

  - by Hulk

  In a template i have the following code <script> var url="/mypjt/my_timer" $.post(url, paramarr, function callbackHandler(dict) { alert('got response back'); if (dict.flag == 2) { alert('1'); $.jGrowl("Data could not be saved"); } else if(dict.ret_status == 1) { alert('2'); $.jGrowl("Data saved successfully"); window.location = "/mypjt/display/" + dict.rid; } }, "json" ); </script> In views i have the following code, def my_timer(request): dict={} try: a= timer.objects.get(pk=1) dict({'flag':1}) return HttpResponse(simplejson.dumps(dict), mimetype='application/javascript') except: dict({'flag':1}) return HttpResponse(simplejson.dumps(dict), mimetype='application/javascript') My question is since we are making a json request and in the try block ,after setting the flag ,cant we return a page directly as return render_to_response('mypjt/display.html',context_instance=RequestContext(request,{'dict': dict})) instead of sending the response, because on success again in the html page we redirect the code Also if there is a exception then only can we return the json request. My only concern is that the interaction between client and server should be minimal. Thanks..

• Filtering and copying with PowerShell

  - by Bergius

  In my quest to improve my PowerShell skills, here's an example of an ugly solution to a simple problem. Any suggestions how to improve the oneliner are welcome. Mission: trim a huge icon library down to something a bit more manageable. The original directory structure looks like this: /Apps and Utilities /Compile /32 Bit Alpha png /Compile 16 n p.png /+ 10 or more files /+ 5 more formats with 10 or more files each /+ 20 or so icon names /+ 22 more categories I want to copy the 32 Bit Alpha pngs and flatten the directory structure a bit. Here's my quick and very dirty solution: $dest = mkdir c:\icons; gci -r | ? { $_.Name -eq '32 Bit Alph a png' } | % { mkdir ("$dest\" + $_.Parent.Parent.Name + "\" + $_.Parent.Name); $_ } | gci | % { cp $_. FullName -dest ("$dest\" + $_.Directory.Parent.Parent + "\" + $_.Directory.Parent) } Not nice, but it solved my problem. Resulting structure: /Apps and Utilities /Compile /Compile 16 n p.png /etc /etc /etc How would you do it?

• Browser pollution / Pop Up request

  - by PatrickS

  From time to time, when I browse the internet , after entering a site's URL , I get a warning message that a pop up has been blocked , then a question mark and a set of numbers appends itself after the URL. It doesn't matter what site I want to navigate to, it can be a site I have developed, a well know site like drupal.org for instance. Here's what happens: enter url: example.com warning: pop up blocked url change to: example.com/?1347628900 After checking the pop up ( which of course turns out to be an unwanted ad ), i deducted that the request and the pop up were linked. This has never happened to me before, I'm not sure how this got started, how can I get rid of this? Clearing the cache , cookies etc... doesn't solve the issue. I'm using a Macbook Pro OS10.6.7 , Chrome 13.0.782.24 beta. Thanks in advance for any tips!

• use awk to identify multi-line record and filtering

  - by nanshi

  I need to process a big data file that contains multi-line records, example input: 1 Name Dan 1 Title Professor 1 Address aaa street 1 City xxx city 1 State yyy 1 Phone 123-456-7890 2 Name Luke 2 Title Professor 2 Address bbb street 2 City xxx city 3 Name Tom 3 Title Associate Professor 3 Like Golf 4 Name 4 Title Trainer 4 Likes Running Note that the first integer field is unique and really identifies a whole record. So in the above input I really have 4 records although I dont know how many lines of attributes each records may have. I need to: - identify valid record (must have "Name" and "Title" field) - output the available attributes for each valid record, say "Name", "Title", "Address" are needed fields. Example output: 1 Name Dan 1 Title Professor 1 Address aaa street 2 Name Luke 2 Title Professor 2 Address bbb street 3 Name Tom 3 Title Associate Professor So in the output file, record 4 is removed since it doen't have the "Name" field. Record 3 doesn't have Address field but still being print to the output since it is a valid record that has "Name" and "Title". Can I do this with awk? But how do i identify a whole record using the first "id" field on each line? Thanks a lot to the unix shell script expert for helping me out! :)

• Filtering foreign keys with AJAX in Django admin

  - by cnobile

  I have most of this figured out already. I have AJAX returning the region/state/province when a country is selected. The correct foreign key is saved to the database, however, when the record is viewed afterwards the selected state is not shown in the select nor are any states for the selected country. I understand why this is happening as, the admin view is not aware of the relation between the state and the country. So here is the question. Is there a hook in the admin view that will allow me to load the correct states for the country and set the selected attribute on the option in the select tag? Or how can I override the admin view for any forms that require the country and region/state/province set? I am using jQuery and Djando-1.1. Thanks

• Filtering on a left join in SQLalchemy

  - by Adam Ernst

  Using SQLalchemy I want to perform a left outer join and filter out rows that DO have a match in the joined table. I'm sending push notifications, so I have a Notification table. This means I also have a ExpiredDeviceId table to store device_ids that are no longer valid. (I don't want to just delete the affected notifications as the user might later re-install the app, at which point the notifications should resume according to Apple's docs.) CREATE TABLE Notification (device_id TEXT, time DATETIME); CREATE TABLE ExpiredDeviceId (device_id TEXT PRIMARY KEY, expiration_time DATETIME); Note: there may be multiple Notifications per device_id. There is no "Device" table for each device. So when doing SELECT FROM Notification I should filter accordingly. I can do it in SQL: SELECT * FROM Notification LEFT OUTER JOIN ExpiredDeviceId ON Notification.device_id = ExpiredDeviceId.device_id WHERE expiration_time == NULL But how can I do it in SQLalchemy? sess.query( Notification, ExpiredDeviceId ).outerjoin( (ExpiredDeviceId, Notification.device_id == ExpiredDeviceId.device_id) ).filter( ??? ) Alternately I could do this with a device_id NOT IN (SELECT device_id FROM ExpiredDeviceId) clause, but that seems way less efficient.

• mysql - filtering a list against keywords, both list and keywords > 20 million records

  - by threecheeseopera

  I have two tables, both having more than 20 million records; table1 is a list of terms, and table2 is a list of keywords that may or may not appear in those terms. I need to identify the terms that contain a keyword. My current strategy is: SELECT table1.term, table2.keyword FROM table1 INNER JOIN table2 ON table1.term LIKE CONCAT('%', table2.keyword, '%'); This is not working, it takes f o r e v e r. It's not the server (see notes). How might I rewrite this so that it runs in under a day? Notes: As for server optimization: both tables are myisam and have unique indexes on the matching fields; the myisam key buffer is greater than the sum of both index file sizes, and it is not even being fully taxed (key_blocks_unused is ... large); the server is a dual-xeon 2U beast with fast sas drives and 8G of ram, fine-tuned for the mysql workload.

• Bad request - Invalid Hostname Error when using ARR IP address

  - by syloc

  I'm trying to setup a simple ARR system. I have 1 ARR machine load balancing between 2 APP servers. I can reach the app sites if i use the server name of the ARR machine. (http://arrserver/app) But i can't do it with its IP address. (http://10.7.10.25/app). It gives the "Bad Request - Invalid Hostname". In the ARR machine i configured the default site's bindings to "All Unassigned","80" (default values). Do i need to change the binding rule or need additional url rewrite rules? And also, in the ARR server http://127.0.0.1/app doesn't work. But http://localhost/app works fine. Thx in advance

• Service Bus / Request Forwarding

  - by codputer

  I'm doing some development with a thrid party that issues either a Get or POST to a public URL that I specify. What I would like to do is set up a Relay service on the Azure Service Bus that my dev machine can listen to. When the request comes in, I want to forward that request as if my web service was taking the request directly from the thrid party service. When I'm ready, I'll deploy the application to a public service, change the URL that the thrid party service is sending too, and viola I should be up and running. What I'm looking for looks exactly like this: Clemens the Master of Service Bus but it's from the 2009 CTP. I'm working at it, but haven't yet got it working using all the new bits in 2012 (a.ka. its over my head at the moment). Somebody want to help? Clemens also help somebody else create a Reverse Proxy using the Service Bus, but I can't seem to find it. Yes I've also tweeted Clemens, but I'm sure he is a busy man! p.s. I know about Application Request Routing, but my dev machine is not on a public URL, I need to rewrite the URL after my client listener on the service bus recieves the message that was relayed from the Server side endpoint.

• Barring connections if VPN is down.

  - by Majid

  I have a VPN account and use it for sensitive communication. However the VPN connection sometimes is dropped while my main connection to the internet is still alive. The pages I visit through VPN are on HTTP (not secure) and have javascript code which pings the host every minute or so on a timer. So it happens sometimes that the VPN connection is dropped and yet js sends a request to the server (with the cookies). How could I restrict connections so they only happen if the VPN is live? Edit - Some required details were missing OS: Windows XP SP2 Browser (mostly used): Google Chrome Firewall: Windows default Sites to filter: not all traffic but all in a list of sites like abc.com, xyz.com

• Problem in filtering records using Dataview (C#3.0)

  - by Newbie

  I have a data table . The data table is basically getting populated from excel sheet. And there are many excel sheets. Henceforth, I have written a utility method for accomplishing the same. Now in some of the excel sheets, there are date columns and in some it is not(only text/string). My function is populating the values properly into the datatable from the excell sheet. But there are many blank rows in the excel sheets some are filled with NULL , some with " ". So I need to filter those records (which are NULL or " " ) first before further processing. What I am after is to use a dataview and apply the filter over there. DataView dv = dataTable.DefaultView; dv.RowFilter = ColumnName + " <> ''"; Well by using metedata (GetOleDbSchemaTable(OleDbSchemaGuid.Columns, restrection)) I was able to get the column names from the excel sheet , so getting the column names is not an issue. But the problem is as I said in some Excel sheet there are date fileds some are not. So the Filter condition of the Dataview needs to be proper. If I apply the above logic, and if it encounters a Datafield, it is throwing error Cannot perform '<' operation on System.DateTime and System.String. Could you people please help me out? I need to filter columns(not known at compile time + their data types) which can have NULL and " " I am using C#3.0 Thanks
