  • Hitting a Button -> Executing any class function I give it in the parameters (C++)

    - by Barnes Noble
    Can anyone help me with class function parameter callbacks? I'm not so sure how to set it up in my code here: http://codepad.org/fvwHtDjQ Basically I've got a player and an enemy. I have two buttons. One button when clicked should let the player jump. The other should make the enemy hit something. When clicked, each button has to correspond to the class function in the parameters. I'm not sure how to set it up though.

  • PHP parameter without value using for navigation

    - by somewalri
    Hello, I am trying to set up a navigation system that uses GET parameters with no value, example: http://foo.bar/?mainPage takes the visitor to the main page. So I am using if statements and I am wondering if there is a way I can do this without a bunch of if statements? I don't think switch statements would work for this. This is currently what I have: $mainPage = $_GET['mainPage']; $contact = $_GET['contact']; if(isset($mainPage)) { // go to main page } if(isset($contact)) { // go to contact page } I don't want to have to end up writing a ton of if statements, though. Any ideas? Thanks.

  • JQuery .get() only passing first two data parameters in url

    - by The.Anti.9
    I have a $.get() call to a PHP page that takes 4 GET parameters. For some reason, despite giving the $.get() call all 4, it only passes the first two. When I look at the dev console in chrome, it shows the URL that gets called, and it only passes action and dbname. Heres the code: $.get('util/util.php', { action: 'start', dbname: db, url: starturl, crawldepth: depth }, function(data) { if (data == 'true') { status = 1; $('#0').append(starturl + "<ul></ul>"); $('#gobutton').hide(); $('#loading').show("slow"); while(status == 1) { setTimeout("update()",10000); } } else { show_error("Form data incomplete!"); } }); and heres the URL that I see in the developer console: http://localhost/pci/util/util.php?action=start&dbname=1hkxorr9ve1kuap2.db

  • Query Execution Failed in Reporting Services reports

    - by Chris Herring
    I have some reporting services reports that talk to Analysis Services and at times they fail with the following error: An error occurred during client rendering. An error has occurred during report processing. Query execution failed for dataset 'AccountManagerAccountManager'. The connection cannot be used while an XmlReader object is open.

  • SSRS2008R2 report times out, but the underlying query executes in the Management Studio

    - by Matthew Belk
    A customer of mine recently moved servers and the new server has SQL2008R2. His old server was SQL2005. The new server has substantially better CPU, RAM, and disk performance than the old, but several reports time out while executing. When I run the underlying query in the SQL Management Studio, the query executes in sub-second time. The exact error message returned via the Report Manager UI is: An error occurred within the report server database. This may be due to a connection failure, timeout or low disk condition within the database. (rsReportServerDatabaseError) Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. It must be noted that this database is not just analytical; it's also fairly transactional, although the transaction volume is not exceptionally high. What can I do to improve the performance of the SSRS query engine? Are there settings in the data source I can adjust, or in the SSRS config files?

  • Mysql Query - That Is Returning Blatanty Incorrect Result

    - by user866190
    I am building a VPS node that is running Ubuntu 10.10LTS, Apache2, Mysql 5.1 and php5. I could not log in to my website admin through the browser, even though I am using the correct login details. So I logged in from the command line to check the results. When I run this query I get expected results: mysql> select * from users; +----+----------+-----------------------+----------+ | id | username | email | password | +----+----------+-----------------------+----------+ | 1 | myUserName | [email protected] | myPassword | +----+----------+-----------------------+----------+ And the same goes for this query: mysql> select * from users where id = 1; +----+----------+-----------------------+----------+ | id | username | email | password | +----+----------+-----------------------+----------+ | 1 | myUserName | [email protected] | myPassword | +----+----------+-----------------------+----------+ 1 row in set (0.00 sec) But when I run this query I get this 'unexpected response': mysql> select * from users where username = 'myUserName' and password = 'myPassword'; Empty set (0.00 sec) I am not sure why this is happening. Any help would be greatly appreciated. BTW.. I will be encrypting the user details but for now I just want to get it set up. Please help, Thanks

  • Automating Access 2007 Queries (changing one criteria)

    - by Graphth
    So, I have 6 queries and I want to run them all once at the end of each month. (I know a bit about SQL but they're simply built using Access's design view). So, in the next few days, perhaps I'll run the 6 queries for May, as May just ended. I only want the data from the month that just ended, so the query has Criteria set as the name of the month (e.g., May). Now, it's not hugely time consuming to change all of these each month, but is there some way to automate this? Currently, they're all set to April and I want to change them all to May when I run them in a few days. And each month, I'd like to type the month (perhaps in a textbox in a form or somewhere else if you know a better way) just once and have it change all 6 queries, without having to manually open all 6, scroll over to the right field and change the Criteria. Note (about VBA): I have used Excel VBA so I know the basics of VBA but I don't really know anything specific to Access (other than seeing code a few times). And, others will use this who do not know anything about Access VBA. So, I think I have found a similar question/answer that could do this in VBA, but I'd rather do it some other way. If the query needs to be slightly redesigned later, probably by someone who doesn't know Access VBA at all, it'd be nice to have a solution not involving VBA if that is even possible.

  • Text editor with coloring to highlight "non-parameters" in conf files?

    - by Zabba
    Some .conf files have a lot of comments and parameters in them like so: # WINS Server - Tells the NMBD components of Samba to be a WINS Client # Note: Samba can be either a WINS Server, or a WINS Client, but NOT both ; wins server = w.x.y.z # This will prevent nmbd to search for NetBIOS names through DNS. dns proxy = no ..... It gets difficult to look for only the parameters among the plethora of comments, so, is there some text editor that can highlight the comments in dark grey so that the real parameters stand out?

  • Running Stored Procedure with parameters resulting from query

    - by David in Dakota
    It's not hard to find developers who think cursors are gauche but I am wondering how to solve the following problem without one: Let's say I have a proc called uspStudentDelete that takes as a parameter @StudentID. uspStudentDelete applies a bunch of cascading soft delete logic, marking a flag on tables like "classes", "grades", and so on as inactive. uspStudentDelete is well vetted and has worked for some time. What would be the best way to run uspStudentDelete on the results of a query (e.g. select studentid from students where ... ) in *TSQL*?

  • Entity Framework How to specify paramter type in generated SQL (SQLServer 2005) Nvarchar vs Varchar

    - by Gratzy
    In entity framework I have an Entity 'Client' that was generated from a database. There is a property called 'Account' it is defined in the storage model as: <Property Name="Account" Type="char" Nullable="false" MaxLength="6" /> And in the Conceptual Model as: <Property Name="Account" Type="String" Nullable="false" /> When select statements are generated using a variable for Account i.e. where m.Account == myAccount... Entity Framework generates a paramaterized query with a paramater of type NVarchar(6). The problem is that the column in the table is data type of char(6). When this is executed there is a large performance hit because of the data type difference. Account is an index on the table and instead of using the index I believe an Index scan is done. Anyone know how to force EF to not use Unicode for the paramater and use Varchar(6) instead?

  • Sharepoint - Passing parameters in URL to NewForm.aspx

    - by kevin
    Any suggestions would be great. I've inherited a system and have been requested to add a context menu item to allow the ability to add a new item. I've set up the context menu with the new option and the newform.aspx to accept and pull parameters from the url for populating some fields. The context menu was created with the content editor web part and the follow JavaScript. function Custom_AddDocLibMenuItems(m, ctx) { var strAction = "window.location='http://address?para1=....'"; var strDisplayText = "Taxonomy"; var strImagePath = ""; // Add our new menu item CAMOpt(m, strDisplayText, strAction, strImagePath); // add a separator to the menu CAMSep(m); // false means that the standard menu items should also be rendered return false; } I'm having difficulties getting the proper values in order to concatenate them to the strAction string (which would be the full url of the newform.aspx. Any suggestions on how I retrieve the values of the columns for the item that the user right click to get context menu.

  • SSRS 2005 - Cascading parameters and default value update problem

    - by sHr0oMaN
    I have a report with cascading parameters. The first parameter is Finanical Period Type, being either Month or Week. The second parameter is a list of either financial months or weeks depending on what was selected for the first parameter. This all works well and selecting a series of different Financial Period Types in sequence correctly updates the second parameter's values. However I now wish to add a default value for the second parameter, which is once again dependent on the first parameter. So I've added an additional field to the dataset populating the second parameter called DefaultPeriod and set the second parameter's default value to be retrieved from the above field. The first time I select the Financial Period Type, the default is correctly set. However changing the Financial Period Type results in an updated list for the second parameter, but the default is incorrect. It remains set to the original default value, even thought the dataset has been refresh and the DefaultPeriod field is correct. This is both an issue in the IDE and on the Report Manager site.

  • Need help understanding "TypeError: default __new__ takes no parameters" error in python

    - by Gordon Fontenot
    For some reason I am having trouble getting my head around __init__ and __new__. I have a bunch of code that runs fine from the terminal, but when I load it as a plugin for Google Quick Search Box, I get the error TypeError: default __new__ takes no parameters. I have been reading about the error, and it's kind of making my brain spin. As it stands I have 3 classes, with no sub-classes, each class has it's own defs. I never use def __init__ or def __new__, but I have gotten the distinct feeling that these are the functions (or the lack thereof) that would be giving me the error. I have no idea how to summarize the code down to a snippet that would be helpful here, since I'm a bit over my head, but the entire script can be found at github. Not expecting anyone to bugfix my code for me, I am just at my wit's end on this. A simple (plain english, not the quote from the python docs which I have read 20 times and still don't really understand) explination of why this error would pop up, or why I should be, or not be, using the __init__ and/or __new__ functions would be seriously appreciated. Thanks for any help you can give in advance.

  • Nested Routes and Parameters for Rails URLs (Best Practice)

    - by viatropos
    Hey there, I have a decent understanding of RESTful urls and all the theory behind not nesting urls, but I'm still not quite sure how this looks in an enterprise application, like something like Amazon, StackOverflow, or Google... Google has urls like this: http://code.google.com/apis/ajax/ http://code.google.com/apis/maps/documentation/staticmaps/ https://www.google.com/calendar/render?tab=mc Amazon like this: http://www.amazon.com/books-used-books-textbooks/b/ref=sa_menu_bo0?ie=UTF8&node=283155&pf_rd_p=328655101&pf_rd_s=left-nav-1&pf_rd_t=101&pf_rd_i=507846&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1PK4ZKN4YWJJ9B86ANC9 http://www.amazon.com/Ruby-Programming-Language-David-Flanagan/dp/0596516177/ref=sr_1_1?ie=UTF8&s=books&qid=1258755625&sr=1-1 And StackOverflow like this: http://stackoverflow.com/users/169992/viatropos http://stackoverflow.com/questions/tagged/html http://stackoverflow.com/questions/tagged?tagnames=html&sort=newest&pagesize=15 So my question is, what is best practice in terms of creating urls for systems like these? When do you start storing parameters in the url, when don't you? These big companies don't seem to be following the rules so hotly debated in the ruby community (that you should almost never nest URLs for example), so I'm wondering how you go about implementing your own urls in larger scale projects because it seems like the idea of not nesting urls breaks down at anything larger than a blog. Any tips?

  • Django: Complex filter parameters or...?

    - by minder
    This question is connected to my other question but I changed the logic a bit. I have models like this: from django.contrib.auth.models import Group class Category(models.Model): (...) editors = ForeignKey(Group) class Entry(models.Model): (...) category = ForeignKey(Category) Now let's say User logs into admin panel and wants to change an Entry. How do I limit the list of Entries only to those, he has the right to edit? I mean: How can I list only those Entries which are assigned to a Category that in its "editors" field has one of the groups the User belongs to? What if User belongs to several groups? I still need to show all relevant Entries. I tried experimenting with changelist_view() and queryset() methods but this problem is a bit too complex for me. I'm also wondering if granular-permissions could help me with the task, but for now I have no clue. I came up only with this: First I get the list of all Groups the User belongs to. Then for each Group I get all connected Categories and then for each Category I get all Entries that belong to these Categories. Unfortunately I have no idea how to stitch everything together as filter() parameters to produce a nice single QuerySet.

  • Administrator's shortcut to batch file with double quoted parameters

    - by XXB
    Take an excruciatingly simple batch file: echo hi pause Save that as test.bat. Now, make a shortcut to test.bat. The shortcut runs the batch file, which prints "hi" and then waits for a keypress as expected. Now, add some argument to the target of the shortcut. Now you have a shortcut to: %path%\test.bat some args The shortcut runs the batch file as before. Now, run the shortcut as administrator. (This is on Windows 7 by the way.) You can use either right-click - Run as Administrator, or go to the shortcut's properties and check the box in the advanced section. Tell UAC that it's okay and once again the shortcut runs the batch file as expected. Now, change the arguments in the target of the shortcut to add double quotes: %path%\test.bat "some args" Now try the shortcut as administrator. It doesn't work this time! A command window pops up and and disappears too fast to see any error. I tried adding test.log 2&1 to the shortcut, but no log is created in this case. Try running the same shortcut (with the double quotes) but not as Administrator. It runs the batch file fine. So, it seems the behavior is not because of the double quoted parameters, and it's not because it's run as Administrator. It's some weird combination of the two. I also tried running the same command from an administrator's command window. This ran the batch file as expected without error. Running the shortcut from the command window spawned a new command window which flashed and went away. So apparently the issue is caused by a combination of administrator, the shortcut, and the double quotes. I'm totally stumped, does anyone have any idea what's going on?

  • Loading Liferay Properties from Spring IoC container (to get jdbc connection parameters)

    - by mox601
    I'm developing some portlets for Liferay Portal 5.2.3 with bundled tomcat 6.0.18 using Spring IoC container. I need to map the User_ table used in Liferay database to an entity with Hibernate, so I need to use two different dataSources to separate the liferay db from the db used by portlets. My jdbc.properties has to hold all connection parameters for both databases: no problem for the one used by portlets, but I am having issues determining which database uses liferay to hold its data. My conclusion is that i should have something like this: liferayConnection.url=jdbc:hsqldb:${liferay.home}/data/hsql/lportal in order to get the database url dynamically loaded, according to Liferay properties found in portal-ext.properties. (Or, better, load the whole portal-ext.properties and read database properties from there). The problem is that the placeholder is not resolved: Caused by: org.springframework.beans.factory.BeanDefinitionStoreException: Invalid bean definition with name 'liferayDataSource' defined in class path resource [WEB-INF/applicationContext.xml]: Could not resolve placeholder 'liferay.home' To dodge this problem I tried to load explicitly portal-ext.properties with a Spring bean: <bean id="liferayPropertiesConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" p:location="../../portal-ext.properties"/> but no luck: liferay.home is not resolved but there aren't other errors. How can I resolve the placeholder defined by Liferay? Thanks

  • Setting corelocation results to NSNumber object parameters

    - by Dan Ray
    This is a weird one, y'all. - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { CLLocationCoordinate2D coordinate = newLocation.coordinate; self.mark.longitude = [NSNumber numberWithDouble:coordinate.longitude]; self.mark.latitude = [NSNumber numberWithDouble:coordinate.latitude]; NSLog(@"Got %f %f, set %f %f", coordinate.latitude, coordinate.longitude, self.mark.latitude, self.mark.longitude); [manager stopUpdatingLocation]; manager.delegate = nil; if (self.waitingForLocation) { [self completeUpload]; } } The latitude and longitude in that "mark" object are synthesized parameters referring to NSNumber iVars. In the simulator, my NSLog output for that line in the middle there reads: 2010-05-28 15:08:46.938 EverWondr[8375:207] Got 37.331689 -122.030731, set 0.000000 -44213283338325225829852024986561881455984640.000000 That's a WHOLE lot further East than 1 Infinite Loop! The numbers are different on the device, but similar--lat is still zero and long is a very unlikely high negative number. Elsewhere in the controller I'm accepting a button press and uploading a file (an image I just took with the camera) with its geocoding info associated, and I need that self.waitingForLocation to inform the CLLocationManager delegate that I already hit that button and once its done its deal, it should go ahead and fire off the upload. Thing is, up in the button-click-receiving method, I test see if CL is finished by testing self.mark.latitude, which seems to be getting set zero...

  • jQuery Flow Control (if then from URL params)

    - by Ryan Max
    Strangely enough I am more familiar with jQuery than I am with javascript. I need to be able to add a class to the body tag of a document depending on what specific forum page i'm on in a phpbb forum. Due to the nature of phpbb I can't actually do this flow control in php, so I am using jquery. Here's my code (the first part is an extend that gets the url parameters like so http://www.mysite.com/viewforum.php?f=3 var forum = $.getUrlVar('f'); will make forum == 3 because of the nature of phpbb i can't really do any flow control with php. So I am using jquery. This is my code: $(document).ready(function(){ $.extend({ getUrlVars: function(){ var vars = [], hash; var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&'); for(var i = 0; i < hashes.length; i++) { hash = hashes[i].split('='); vars.push(hash[0]); vars[hash[0]] = hash[1]; } return vars; }, getUrlVar: function(name){ return $.getUrlVars()[name]; } }); }); $(document).ready(function(){ var forum = $.getUrlVar('f'); if (forum == 3){ $('body').toggleClass('black'); } }); Yet this isn't working. Any idea why not?

So, There's no declaration of parameters size before calling procedure. Thanks in advance for your reply.

  • ASP.Net MVC Json Result: Parameters passed to controller method issue

    - by Moskie
    I'm having a problem getting a controller method that returns a JsonResult to accept parameters passed via the JQuery getJSON method. The code I’m working on works fine when the second parameter ("data") of the getJSON method call is null. But when I attempt to pass in a value there, it seems as if the controller method never even gets called. In this example case, I just want to use an integer. The getJSON call that works fine looks like this: $.getJSON(”/News/ListNewsJson/”, null, ListNews_OnReturn); The controller method is like this: public JsonResult ListNewsJson(int? id) { … return Json(toReturn); } By putting a breakpoint in the ListNewsJson method, I see that this method gets called when the data parameter of getJSON is null, but when I replace it with value, such as, say, 3: $.getJSON(”/News/ListNewsJson/”, 3, ListNews_OnReturn); … the controller method/breakpoint is never hit. Any idea what I'm doing wrong? I should also mention that the controller method works fine if I manually go to the address via my browser ("/News/ListNewsJson/3").
