• Sign in as different user when using Integrated Windows Authentication

  - by Sam

  I have restricted access to a site by using Integrated Windows Authentication and turning off anonymous access. This way I can then show them their real name (from looking up on Active Directory and using the server variable LOGON_USER) and do other related Active Directory tasks. How can I then prompt again for their user credentials, through a 'sign in as other user' link , showing the browser prompt (like you would get on a browser like Chrome or Firefox, or if the site was not in the 'Intranet' zone in IE) rather than a Web Form? Since SharePoint offers this functionality, I assume there is a way to do this through code, but I don't know what code can do this (using C#). I can send a 401 header which makes the prompt appear, but how do you then confirm if they are logged in?

• MYOB Service Sales Import

  - by sjw

  I have developed an export file from our Job Management system that I want to be able to import into MYOB Accounting Plus v18.5. The file is generated without issue and I have included every single field to make it easy for upload (i.e. Match All matches every field) The problem I am having is no matter what I do, I cannot get the sales to import... Every time, no matter what I do or how I create the customer card comes back with: Error -190: Customer not found. Sale invoice not imported. I have tried matching using - co./Last Name, Card ID & Record ID and every time I get the same error. I have created a single customer with a simply Co./Last Name, Card ID & Record ID and still, when I try to import using these same fields exactly matched, I get the same error...

• Display using QtWebKit, whilst parsing xml

  - by Beren Scott

  I wish to use QtWebKit to load a url for display, but, that's the easy part, I can do that. What I wish to do is record / log xml as I go. My attention here is to record and database certain details on the fly, by recording those details. My problem is, how to do this all on the fly, without requesting the same url from the server twice, once for the xml, and the second time to view the url. My hope here, is to implement a very fast way of recording set data as the user passes over it. Take for example, rather then have to type out details displayed by a website, I wish to have those details chucked into a database as I the user views the website. Now, I am using QtWebKit, and I have everything pretty much solved viewing wise. I have a loadUrl() routine which calls load(url) inside the qwebview.h The problem is, how do I piggyback xml parsing on top of this?

• How do I execute a cmd in C#, then in the same window execute another command that follows?

  - by Ashh

  Hey Guys, Right what im trying to accomplish is a program that basically sets the active partition in 1 click, saving the effort time and skill of using cmd prompt etc. I have looked into the System.Management name space but couldn't work out how to use it :( So i have resorted to using CMD, i have got a module application written in C# and basically i want to run "DISKPART" which then starts the diskpart in the cmd window, then i want to ask it to "Select disk 0" followed by "select partition 1" finally followed by "active". Doing this in CMD yourself works fine but with an application its proved to be awkward :( What ive managed to get it to do is run DiskPart fine in one window with Process.Start, then get it to open a new window and run the next piece of code but because the new window hasnt ran the diskpart cmd it doesnt work :( Any suggestions? Thanks! Ash

• Monitor database table for external changes from within Rails application

  - by jhwist

  I'm integrating some non-rails-model tables in my Rails application. Everything works out very nicely, the way I set up the model is: class Change < ActiveRecord::Base establish_connection(ActiveRecord::Base.configurations["otherdb_#{RAILS_ENV}"]) set_table_name "change" end This way I can use the Change model for all existing records with find etc. Now I'd like to run some sort of notification, when a record is added to the table. Since the model never gets created via Change.new and Change.save using ActiveRecord::Observer is not an option. Is there any way I can get some of my Rails code to be executed, whenever a new record is added? I looked at delayed_job but can't quite get my head around, how to set that up. I imagine it evolves around a cron-job, that selects all rows that where created since the job last ran and then calls the respective Rails code for each row.

• (My)SQL performance: updating one field vs many unneccesary fields

  - by changokun

  i'm processing a form that has a lot of fields for a user who is editing an existing record. the user may have only changed one field, and i would typically do an update query that sets the values of all the fields, even though most of them don't change. i could do some sort of tracking to see which fields have actually changed, and only update the few that did. is there a performance difference between updating all fields in a record vs only the one that changed? are there other reasons to go with either method? the shotgun method is pretty easy...

• PIG doesn't read my custom InputFormat

  - by Simon Guo

  I have a custom MyInputFormat that suppose to deal with record boundary problem for multi-lined inputs. But when I put the MyInputFormat into my UDF load function. As follow: public class EccUDFLogLoader extends LoadFunc { @Override public InputFormat getInputFormat() { System.out.println("I am in getInputFormat function"); return new MyInputFormat(); } } public class MyInputFormat extends TextInputFormat { public RecordReader createRecordReader(InputSplit inputSplit, JobConf jobConf) throws IOException { System.out.prinln("I am in createRecordReader"); //MyRecordReader suppose to handle record boundary return new MyRecordReader((FileSplit)inputSplit, jobConf); } } For each mapper, it print out I am in getInputFormat function but not I am in createRecordReader. I am wondering if anyone can provide a hint on how to hoop up my costome MyInputFormat to PIG's UDF loader? Much Thanks. I am using PIG on Amazon EMR.

• What databse uses these specific type of .dat and .idx files?

  - by Cape Cod Gunny

  I'm trying to figure out what type of database uses these specific .dat and .idx files. When I view the .dat files using a binary file reader I see Record Schema followed by somewhat decipherable data names. A little further down I see Key Schema whch apears to be a comma separated list of clear text references. Each .dat file has a matching .idx file. Each .dat file contains the phrase "Record Schema" and "Key Schema" as described above. How would I convert these files so I can use them in an SQL database?

• Ajax load div , part of CSS not working

  - by user225228

  Hello, I'm using the ajax to load a div content, but the div content is not taking the CSS of the page. Example :- This link will load into <a href="#" onclick="javascript:loadAjax('test.html')">Test</a> <div id="result"> <table class="tablesorter"> <thead> <tr> <th>Header 1</th><th>Header 2</th> </tr> </thead> <tbody> <tr><td>Record 1</td><td>Desc 1</td></tr> </tbody> </table> </div> In my CSS : table.tablesorter thead tr th, table.tablesorter tfoot tr th { background-color: #e6EEEE; border: 1px solid #FFF; font-size: 8pt; padding: 4px; } table.tablesorter thead tr .header { background-image: url(bg.gif); background-repeat: no-repeat; background-position: center right; cursor: pointer; } In my test.html, it's the same table with different record : <table class="tablesorter"> <thead> <tr> <th>Header 1</th><th>Header 2</th> </tr> </thead> <tbody> <tr><td>Record 2</td><td>Desc 2</td></tr> </tbody> </table> The issue I'm facing is that before "test.html" is load, the CSS is fine. But after clicking on the link which suppose to loads test.html, the CSS background still shows but "cursor:pointer" and "background-image" not longer works. What should I do to make it work? Thanks in advance!

• SQL 2005 w/ C# optimal "Paging"

  - by David Murdoch

  When creating a record "grid" with custom paging what is the best/optimal way to query the total number of records as well as the records start-end using C#? SQL to return paged record set: SELECT Some, Columns, Here FROM ( SELECT ROW_NUMBER() OVER (ORDER BY Column ASC) AS RowId, * FROM Records WHERE (...) ) AS tbl WHERE ((RowId > @Offset) AND (RowId <= (@Offset + @PageSize)) ) SQL to count total number of records: SELECT COUNT(*) FROM Records WHERE (...) Right now, I make two trips to the server: one for getting the records, and the other for counting the total number of records. What is/are the best way(s) to combine these queries to avoid multiple DB trips?

• How to create Master/Detail view with two datagrids in ColdFusion

  - by Maklar

  In Coldfusion, I have Master and Detail data that I need to display in two separate cfgrids; like the typical Customers/Orders scenario. My cfgrids are bound to cfc functions which populate the cfgrids. In my current dataset, only one Customer has Orders and when I click on this record in the Master datagrid the Detail datagrid displays the related records. But when I click on a record in the Master datagrid that has no related detail records, the Detail datagrid does not refresh but maintains display of the previous data. Also the search icon within the datagrid's control panel indicates it is searching for values rather than displaying the Refresh icon. Can you please show me how to establish Master and Detail cfgrids where I can see Orders of Customers as I navigate through the Master datagrid? Any and all help will be greatly appreciated! Maklar

• MVC validation error with strongly typed view

  - by Remnant

  I have a simple form that I would like to validate on form submission. Note I have stripped out the html for ease of viewing <%=Html.TextBox("LastName", "")%> //Lastname entry <%=Html.ValidationMessage("LastName")%> <%=Html.TextBox("FirstName", "")%>//Firstname entry <%=Html.ValidationMessage("FirstName")%> <%=Html.DropDownList("JobRole", Model.JobRoleList)%> //Dropdownlist of job roles <% foreach (var record in Model.Courses) // Checkboxes of different courses for user to select { %> <li><label><input type="checkbox" name="Courses" value="<%=record.CourseName%>" /><%= record.CourseName%></label></li> <% } %> On submission of this form I would like to check that both FirstName and LastName are populated (i.e. non-zero length). In my controller I have: public ActionResult Submit(string FirstName, string LastName) { if (FirstName.Trim().Length == 0) ModelState.AddModelError("FirstName", "You must enter a first name"); if (LastName.Trim().Length == 0) ModelState.AddModelError("LastName", "You must enter a first name"); if (ModelState.IsValid) { //Update database + redirect to action } return View(); //If ModelState not valid, return to View and show error messages } Unfortunately, this code logic produces an error that states that no objects are found for JobRole and Courses. If I remove the dropdownlist and checkboxes then all works fine. The issue appears to be that when I return the View the view is expecting objects for the dropwdownlist and checkboxes (which is sensible as that is what is in my View code) How can I overcome this problem? Things I have considered: In my controller I could create a JobRoleList object and Course object to pass to the View so that it has the objects to render. The issue with this is that it will overwrite any dropdownlist / checkbox selections that the user has already made. In the parameters of my controller method Submit I could aslo capture the JobRoleList object and Course object to pass back to the View. Again, not sure this would capture any items the user has already selected. I have done much googling and reading but I cannot find a good answer. When I look at examples in books or online (e.g. Nerddinner) all the validation examples involve simple forms with TextBox inputs and don't seems to show instances with multiple checkboxes and dropdownlists. Have I missed something obvious here? What would be best practice in this situation? Thanks

• Problem with images in upload directory after upgrading WordPress to 3.0

  - by Volmar

  I've developed a WordPress plugin and it wordked well from WP 2.0 and up to WP 3.0rc1 (haven't tried rc2) but now with rc3 and milestone 3.0 a strange and irritating error appeared. If you check out my demo page you will se that none of the cover-images is working. they are in the same place as before but they can not be hotlinked or show up when i enter the correct url. if i move the img-directory from /wp-content/uploads/my-record-collection/ to /wp-content/uploads/ the images show up if i enter the url, but not if i move it back inside my "my-record-collection"-folder. anyone know what change in rc3(or maybe rc2) that made this bug appear and what can be done to fix it?

• Thinking of an Inner Join as a Cross Join and then satisfying some condition(s)?

  - by Jian Lin

  It seems like the safest way to think of an Inner Join is to think of it as a Cross Join and then satisfying some condition(s)? Because the equi-join can be obvious, but the non-equi-join can be a bit confusing. But if we always use the Cross Join, and then filter out the ones satisfying the condition, then we get the resulting table. In other words, we can always analyze it by using the first record on the left table, and then go through every single records on the right, and then repeat that for 2nd record on the left, and for the 3rd, 4th, ... etc. So in our mind, we can analyze it using this way, and it is like O(n^2), although what happens in the DBMS maybe that it is a lot faster (when an index is present). Is there another good way to think of it besides this method?

• how to modify this jquery syntax

  - by Gandalf StormCrow

  Hi all, this example below works when hover event is trigered and when its not, its working for elements already in DOM, but when element created dynamically it doesn't work, I realize I need to use jQuery live() or delegate() for this, the thing is I tried to modify it and its not producing the results as expected, here is the working code : $(".sidebar li").hover( function(){ $(this).css("background-color", "#F9F4D0"); $(this).append($('<button class="promoter" type="button" title="Active promotion"></button>')); }, function(){ $(this).css("background-color", "#F9FAFA"); $(this).children("button").remove(); } ); Here is the bit when I wanted to add live but it's not producing correct results : $(".sidebar li").live('hover', function(){ $(this).css("background-color", "#F9F4D0"); $(this).append($('<button class="promoter" type="button" title="Active promotion"></button>')); }, function(){ $(this).css("background-color", "#F9FAFA"); $(this).children("button").remove(); } ); Where did I made mistake, thank you

• How to read line by line a CR-only file with Perl?

  - by Subb

  Hi, I'm trying to read a file which has only CR as line delimiter. I'm using Mac OS X and Perl v.5.8.8. This script should run on every platform, for every kind of line delimiter (CR, LF, CRLF). My current code is the following : open(FILE, "test.txt"); while($record = <FILE>){ print $record; } close(TEST); This currently print only the last line (or worst). What is going on? Obvisously, I would like to not convert the file. Is it possible?

• Does Ruby on Rails "has_many" array provide data on a "need to know" basis?

  - by Jian Lin

  On Ruby on Rails, say, if the Actor model object is Tom Hanks, and the "has_many" fans is 20,000 Fan objects, then actor.fans gives an Array with 20,000 elements. Probably, the elements are not pre-populated with values? Otherwise, getting each Actor object from the DB can be extremely time consuming. So it is on a "need to know" basis? So does it pull data when I access actor.fans[500], and pull data when I access actor.fans[0]? If it jumps from each record to record, then it won't be able to optimize performance by doing sequential read, which can be faster on the hard disk because those records could be in the nearby sector / platter layer -- for example, if the program touches 2 random elements, then it will be faster just to read those 2 records, but what if it touches all elements in random order, then it may be faster just to read all records in a sequential way, and then process the random elements. But how will RoR know whether I am doing only a few random elements or all elements in random?

• Multitenant shared user account?

  - by jpartogi

  Dear all, Based on your experience, which is the route to go for a multi-tenant user login? One user login per account. Which means if there is one user that has access to multiple account, there will be redundancy of record in the database One user login for all account that she has privileges to. Which means one user record has access to multiple account if she has privileges to that account. From your experience, which one is better and why? I was thinking to choose the latter, but I don't know whether it will cause security issue or less flexibility. Thank you for sharing your experience.

• Dynamically removing records when certain columns = 0; data cleansing

  - by cdburgess

  I have a simple card table: CREATE TABLE `users_individual_cards` ( `id` int(11) NOT NULL AUTO_INCREMENT, `user_id` char(36) NOT NULL, `individual_card_id` int(11) NOT NULL, `own` int(10) unsigned NOT NULL, `want` int(10) unsigned NOT NULL, `trade` int(10) unsigned NOT NULL, PRIMARY KEY (`id`), UNIQUE KEY `user_id` (`user_id`,`individual_card_id`), KEY `user_id_2` (`user_id`), KEY `individual_card_id` (`individual_card_id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1; I have ajax to add and remove the records based on OWN, WANT, and TRADE. However, if the user removes all of the OWN, WANT, and TRADE cards, they go to zero but it will leave the record in the database. I would prefer to have the record removed. Is checking after each "update" to see if all the columns = 0 the only way to do this? Or can I set a conditional trigger with something like: //psuedo sql AFTER update IF (OWN = 0, WANT = 0, TRADE = 0) DELETE What is the best way to do this? Can you help with the syntax?

• Setting Grouping in UITableView under UINavigationController

  - by climbon

  In my UINavigationController app, my first view is a UITableView. I can't seem to find a way to set the property of this UITableView to 'grouped'. Since UITableView is dynamically generated I don't have the luxury of Interface Builder. Searched forums here and googled other places and closest I saw was to override either initWithStyle or initWithCoder as follows. (id)initWithStyle:(UITableViewStyle)style { if (self = [super initWithStyle:UITableViewStyleGrouped]) { } return self; } However this above function never gets called. when I overrided initWithCoder I could see it worked and I was able to change UITableView contents to grouped. But then title automatically became 'Root View Controller' and none of the cells were active anymore although they got grouped fine. That is while they looked active but if you click on them, those cells won't do anything. But I have seen apps which have their very first view being UITableView is grouped. So there must be a way to do it but I don't know how.
