Swing layout with miglayout and nested panels

- by Jazzepi

I have a Swing program using SwingLayout. The structure of the Swing components looks like this. JFrame JPanel (Cardlayout) JPanel (Miglayout) - Main panel Jpanel (Flowlayout) - Checkbox Panel JPanel (Flowlayout) - Option Panel My problem right now is that I'm not sure how to prevent the checkbox panel from growing. I don't want it to "push" out the column that it's in to the right. I want Wraplayout (which works fine on the option panel) to wrap the content of the checkbox panel when it grows too big. This is the view of it from the Windowsbuilder GUI inside of Eclipse. The panel with the label "sites" in it is the Checkbox Panel. Directly to the right of the Checkbox panel is the Option panel. The big panel containing both of them is the main panel. http://i.imgur.com/S7Njo.png This is what happens when I add too many checkboxes http://i.imgur.com/f2SZz.png My main problem is that I don't understand why setting "grow 0" on the column constraint for the first column in mainpanel doesn't prevent it from growing when the component inside gets too big as I add new checkboxes to the site panel (the site panel can have an arbitrary number of checkboxes). This is my miglayout for the main panel. mainPanel.setLayout(new MigLayout("", "[][grow]", "[][][][][][][][grow]")); Here are my component constraints for when I add the checkbox panel siteCheckBoxPanel = new JPanel(); mainPanel.add(siteCheckBoxPanel, "cell 0 0,alignx left,gapx 0px,aligny center"); siteCheckBoxPanel.setLayout(new FlowLayout(FlowLayout.CENTER, 5, 5)); I've also tried it without flow layout, and that doesn't fix anything. Any insight you could provide would be great! I'm also happy to provide more information if people have questions. FYI I've also tried "grow 0" on both the column and row constraint for the cell that the Checkbox Panel is inside.

Inserting variable into routes - map.resources :posts, :as => X - is this possible?

- by bgadoci

Ok, so I am working on a blog application of sorts. Thus far, it allows for a user to sign up for their own account, create posts, tags, comments, etc. I have just implemented the ability to use www.myapp.com/brandon to set @user to find by username and therefore correctly display the users information at each url. So when you go to www.myapp.com/brandon you see all Brandon's posts, tags, and comments associated with those posts, etc. Works great. I'm implementing this URL mapping through the routes.rb file by adding the following: map.username_link '/:username', :controller => 'posts', :action => 'index' And then just setting the @user variable in the PostController and corresponding views to find_by_username. Now the issue is this. Once at www.myapp.com/brandon when you click on a post title, it sends to myapp.com/posts/id without the username in the URL. How do I tell rails to replace the /posts with /username. Is it even possible to insert the user_username variable into this code? map.resources :posts, :as => [what goes here]

dximagetransform.matrix, absolutely position child elements not rotating in IE 8 standards mode

- by davydka

I've looked all over for more information on this, and would like to know why it happens. Here's the code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> </head> <body> <div style="position:absolute; top:200px; left:200px; height:200px; width:200px; border:1px solid black; filter: progid:DXImageTransform.Microsoft.Matrix(sizingMethod='auto expand', M11=0.9886188373396114, M12=-0.15044199698646263, M21=0.15044199698646263, M22=0.9886188373396114);"> <div style="position:absolute; top:10px; left:10px; border:1px solid darkblue;"> I do not rotate in IE 8. </div> </div> </body> </html> The problem is that absolutely or relatively positioned elements within a div that has been rotated using MS's dximagetransform.matrix do not inherit the transformation in IE 8. IE 6 & 7 render correctly, and I can solve the IE8 problem by triggering compatibility mode, but I'd rather not do that. Does anyone have any experience with this? I'm using css3 transform on other browsers and using dximagetransform.matrix to achieve this effect in IE. EDIT: Added the opening html tag. Problem still exists. http://i45.tinypic.com/nf4gmq.png

Broken tables in RichTextBox control (word wrap)

- by Ben Robbins

We are having problems with the Windows.Forms.RichTextBox control in Visual Studio 2008. We are trying to display text supplied as an RTF file by a 3rd party in a windows forms application (.NET 3.5). In this RTF text file there are tables, which contain text that spans multiple lines. The RTF file displays correctly when opened with either WordPad or Word 2003. However, when we load the RTF file into the RichTextBox control, or copy & paste the whole text (including the table) into the control, the table does not display correctly - the cells are only single line, without wrapping. Here are links to images showing the exact problem: Correctly displayed in WordPad Incorrectly displayed in RichTextBox control I have googled for solutions and 3rd party .net RTF controls without success. I have found this exact problem asked on another forum without an answer (in fact that's where the link to the images come from) so I'm hoping stack overflow does better ;-) My preferred solution would be to use code or a 3rd party control that can correctly render the RTF. However, I suspect the problem is that the RichTextBox control only supports a subset of the full RTF spec, so another option would be to modify the RTF directly to remove the unsupported control codes or otherwise fix the RTF file itself (in which case any information as to what control codes need to be removed or modified would be a huge help).

Pass table as parameter to SQLCLR TV-UDF

- by Skeolan

We have a third-party DLL that can operate on a DataTable of source information and generate some useful values, and we're trying to hook it up through SQLCLR to be callable as a table-valued UDF in SQL Server 2008. Taking the concept here one step further, I would like to program a CLR Table-Valued Function that operates on a table of source data from the DB. I'm pretty sure I understand what needs to happen on the T-SQL side of things; but, what should the method signature look like in the .NET (C#) code? What would be the parameter datatype for "table data from SQL Server?" e.g. /* Setup */ CREATE TYPE InTableType AS TABLE (LocationName VARCHAR(50), Lat FLOAT, Lon FLOAT) GO CREATE TYPE OutTableType AS TABLE (LocationName VARCHAR(50), NeighborName VARCHAR(50), Distance FLOAT) GO CREATE ASSEMBLY myCLRAssembly FROM 'D:\assemblies\myCLR_UDFs.dll' WITH PERMISSION_SET = EXTERNAL_ACCESS GO CREATE FUNCTION GetDistances(@locations InTableType) RETURNS OutTableType AS EXTERNAL NAME myCLRAssembly.GeoDistance.SQLCLRInitMethod GO /* Execution */ DECLARE @myTable InTableType INSERT INTO @myTable(LocationName, Lat, Lon) VALUES('aaa', -50.0, -20.0) INSERT INTO @myTable(LocationName, Lat, Lon) VALUES('bbb', -20.0, -50.0) SELECT * FROM @myTable DECLARE @myResult OutTableType INSERT INTO @myResult MyCLRTVFunction @myTable --returns a table result calculated using the input The lat/lon - distance thing is a silly example that should of course be better handled entirely in SQL; but I hope it illustrates the general intent of table-in - table-out through a table-valued UDF tied to a SQLCLR assembly. I am not certain this is possible; what would the SQLCLRInitMethod method signature look like in the C#? public class GeoDistance { [SqlFunction(FillRowMethodName = "FillRow")] public static IEnumerable SQLCLRInitMethod(<appropriateType> myInputData) { //... } public static void FillRow(...) { //... } } If it's not possible, I know I can use a "context connection=true" SQL connection within the C# code to have the CLR component query for the necessary data given the relevant keys; but that's sensitive to changes in the DB schema. So I hope to just have SQL bundle up all the source data and pass it to the function. Bonus question - assuming this works at all, would it also work with more than one input table?

What is private bytes, virtual bytes, working set?

- by Devil Jin

I am using perfmon windows utility to debug memory leak in a process. Perfmon explaination: Working Set- Working Set is the current size, in bytes, of the Working Set of this process. The Working Set is the set of memory pages touched recently by the threads in the process. If free memory in the computer is above a threshold, pages are left in the Working Set of a process even if they are not in use. When free memory falls below a threshold, pages are trimmed from Working Sets. If they are needed they will then be soft-faulted back into the Working Set before leaving main memory. Virtual Bytes- Virtual Bytes is the current size, in bytes, of the virtual address space the process is using. Use of virtual address space does not necessarily imply corresponding use of either disk or main memory pages. Virtual space is finite, and the process can limit its ability to load libraries. Private Bytes- Private Bytes is the current size, in bytes, of memory that this process has allocated that cannot be shared with other processes. Q1. Is it the private byte should I measure to be sure if the process is having any leak as it does not involve any shared libraries and any leak if happening will be coming from the process itself? Q2. What is the total memory consumed by the process? Is it the Virtual byte size? or Is it the sum of Virtual Bytes and Working Set Q3. Is there any relation between private bytes, working set and virtual bytes. Q4. Any tool which gives a better idea memory information?

C# - WinForms - Exception Handling for Events

- by JustLooking

Hi all, I apologize if this is a simple question (my Google-Fu may be bad today). Imagine this WinForms application, that has this type of design: Main application - shows one dialog - that 1st dialog can show another dialog. Both of the dialogs have OK/Cancel buttons (data entry). I'm trying to figure out some type of global exception handling, along the lines of Application.ThreadException. What I mean is: Each of the dialogs will have a few event handlers. The 2nd dialog may have: private void ComboBox_SelectedIndexChanged(object sender, EventArgs e) { try { AllSelectedIndexChangedCodeInThisFunction(); } catch(Exception ex) { btnOK.enabled = false; // Bad things, let's not let them save // log stuff, and other good things } } Really, all the event handlers in this dialog should be handled in this way. It's an exceptional-case, so I just want to log all the pertinent information, show a message, and disable the okay button for that dialog. But, I want to avoid a try/catch in each event handler (if I could). A draw-back of all these try/catch's is this: private void someFunction() { // If an exception occurs in SelectedIndexChanged, // it doesn't propagate to this function combobox.selectedIndex = 3; } I don't believe that Application.ThreadException is a solution, because I don't want the exception to fall all the way-back to the 1st dialog and then the main app. I don't want to close the app down, I just want to log it, display a message, and let them cancel out of the dialog. They can decide what to do from there (maybe go somewhere else in the app). Basically, a "global handler" in between the 1st dialog and the 2nd (and then, I suppose, another "global handler" in between the main app and the 1st dialog). Thanks.

Increase Query Speed in PostgreSQL

- by Anthoni Gardner

Hello, First time posting here, but an avid reader. I am experiancing slow query times on my database (all tested locally thus far) and not sure how to go about it. The database itself has 44 tables and some of them tables have over 1 Million records (mainly the movies, actresses and actors tables). The table is made via JMDB using the flat files on IMDB. Also the SQL query that I am about to show is from that said program (that too experiances very slow search times). I have tried to include as much information as I can, such as the explain plan etc. "QUERY PLAN" "HashAggregate (cost=46492.52..46493.50 rows=98 width=46)" " Output: public.movies.title, public.movies.movieid, public.movies.year" " - Append (cost=39094.17..46491.79 rows=98 width=46)" " - HashAggregate (cost=39094.17..39094.87 rows=70 width=46)" " Output: public.movies.title, public.movies.movieid, public.movies.year" " - Seq Scan on movies (cost=0.00..39093.65 rows=70 width=46)" " Output: public.movies.title, public.movies.movieid, public.movies.year" " Filter: (((title)::text ~~* '%Babe%'::text) AND ((title)::text !~~* '""%}'::text))" " - Nested Loop (cost=0.00..7395.94 rows=28 width=46)" " Output: public.movies.title, public.movies.movieid, public.movies.year" " - Seq Scan on akatitles (cost=0.00..7159.24 rows=28 width=4)" " Output: akatitles.movieid, akatitles.language, akatitles.title, " Filter: (((title)::text ~~* '%Babe%'::text) AND ((title)::text !~~* '""%}'::text))" " - Index Scan using movies_pkey on movies (cost=0.00..8.44 rows=1 width=46)" " Output: public.movies.movieid, public.movies.title, public.movies.year, public.movies.imdbid" " Index Cond: (public.movies.movieid = akatitles.movieid)" SELECT * FROM ((SELECT DISTINCT title, movieid, year FROM movies WHERE title ILIKE '%Babe%' AND NOT (title ILIKE '"%}')) UNION (SELECT movies.title, movies.movieid, movies.year FROM movies INNER JOIN akatitles ON movies.movieid=akatitles.movieid WHERE akatitles.title ILIKE '%Babe%' AND NOT (akatitles.title ILIKE '"%}'))) AS union_tmp2; Returns 612 Rows in 9078ms Database backup (plain text) is 1.61GB It's a really complex query and I am not fully cognizant on it, like I said it was spat out by JMDB. Do you have any suggestions on how I can increase the speed ? Regards Anthoni

CakePHP 1.3 and Uploadifive/Uploadify - Change Upload Filename to a random string

- by CaboONE

I have somehow implemented UPLOADIFIVE in my CakePHP application. Everything seems to work great including uploading multiple files and inserting the correct information in the Database. Based on the following code, I would like to UPLOAD AND SAVE EVERY FILE WITH A RANDOM NAME TAKING INTO ACCOUNT THE CURRENT DATE OR SOMETHING SIMILAR. How could I accomplish this? In my Photos Controller I have the following function: // This function is called at every file upload. It uploads the file onto the server // and save the corresponding image name, etc, to the database table `photos`. function upload() { $uploadDir = '/img/uploads/photos/'; if (!empty($_FILES)) { debug($_FILES); $tempFile = $_FILES['Filedata']['tmp_name'][0]; $uploadDir = $_SERVER['DOCUMENT_ROOT'] . $uploadDir; $targetFile = $uploadDir . $_FILES['Filedata']['name'][0]; // Validate the file type $fileTypes = array('jpg', 'jpeg', 'gif', 'png'); // Allowed file extensions $fileParts = pathinfo($_FILES['Filedata']['name'][0]); // Validate the filetype if (in_array($fileParts['extension'], $fileTypes)) { // Save the file move_uploaded_file($tempFile,$targetFile); $_POST['image'] = $_FILES['Filedata']['name'][0]; $this->Photo->create(); if ($this->Photo->save($_POST)) { $this->Session->setFlash($targetFile, 'default', array('class' => 'alert_success')); $this->redirect(array('action' => 'index')); } } else { // The file type wasn't allowed //echo 'Invalid file type.'; $this->Session->setFlash(__('The photo could not be saved. Please, try again.', true)); } } } In my View file - admin_add.ctp I have added the following function $('#file_upload').uploadifive({ 'auto' : false, 'uploadScript' : '/photos/upload', 'buttonText' : 'BROWSE FILES', 'method' : 'post', 'onAddQueueItem' : function(file) { this.data('uploadifive').settings.formData = { 'photocategory_id' : $('#PhotoPhotocategoryId').val() }; } }); <input type="file" name="file_upload" id="file_upload" />

DotNetOpenAuth OpenID on ISA 2006 Reverse Proxy problem

- by userb00

I am trying to host my site that uses DotNetOpenAuth (OpenID) behind ISA 2006 (reverse proxy), and after it authenticated with a provider (such as Google), and it returns with a URL with %253A in the URL. However, ISA HTTP filter rejects the request. What I need to do is, on ISA web publishing rule, right click config HTTP policy properties uncheck "Verify Normalization" and it worked. Is this a problem on ISA 2006 generally? Are other firewalls having similar problems? Or, is it an OpenID or DotNetOpenAuth issue? Is it safe to disable Normalization checking on ISA? According to MSDN, quote "Web servers receive requests that are URL encoded. This means that certain characters may be replaced with a percent sign (%) followed by a particular number. For example, %20 corresponds to a space, so a request for http://myserver/My%20Dir/My%20File.htm is the same as a request for http://myserver/My Dir/My File.htm. Normalization is the process of decoding URL-encoded requests. Because the % can be URL encoded, an attacker can submit a carefully crafted request to a server that is basically double-encoded. If this occurs, Internet Information Services (IIS) may accept a request that it would otherwise reject as not valid. When you select Verify Normalization, the HTTP filter normalizes the URL two times. If the URL after the first normalization is different from the URL after the second normalization, the filter rejects the request. This prevents attacks that rely on double-encoded requests. Note that while we recommend that you use the Verify Normalization function, it may also block legitimate requests that contain a %."

Developing a rich internet application

- by Serge

Hello, I have been a desktop developer for a few years mostly doing object oriented stuff. I am trying to branch out into web development, and as a hobby project trying to put a web application together. I have been reading quite alot of information, but I still can't seem to decide on the path to take and would really like some advice. Basically, I want to build something like this: http://mon.itor.us/ I have found this as well: http://www.trilancer.com/jpolite/#t1 But so far it is of little use as I am trying to grasp Javascript. I have been using visual studio for that, is that a good IDE for this tye of thing or should I try expression blend? Jpolite seems to do everything with javascript, which seems kind of cool, but I if I want to make a chart inside a widget that connects to a database, do I need something more? Is this where ASP.NET comes in? I am familiar with .NET, but if I use ASP.NET for my website, do I have to host it on IIS and windows server as opposed to Apache since mono is still being ironed out? Because that would cost more, so would PHP be a better choice? Also, for charting these guys as well as google seem to use flex: http://www.google.com/finance I have found this: http://www.reynoldsftw.com/2009/03/javascript-chart-alternatives/ Would that be sufficient to implement something like google fiance purely in javascript or is there a good reason they use flex? SOrry for the long post but I was trying to be as detailed as possible. Thanks.

Advice needed on best and most efficient practices with developing google apps application...

- by Ali

Hi guys , I'm getting my feet wet with developing my order management applications for integration with google apps. However there are certain aspects I need to take into consideration prior to proceeding any further. My application is such that it would upload documents to google documents and store contacts in google contacts. It requires such that a single order can have a number of uploaded documents associated with it as well as some contacts associated with it. MY question however is what would be the most efficient way to implement this. I could keep key tables for both contacts and documents which woudl contain just an ID and link to the documents/contacts or their respective identification id on google. Or I could maintain an exact replica of the information on my own database as well as a link to the contact on google. However won't that be too redundant. I don't want my application to be really slow as I'm afraid that everytime I make a call to google docs to retrieve a list of documents or google contacts it would be really slow on my application - or am I getting worried for no reason? Any advice would be most appreciated.

configure batch to sent minute info instead of entire stdout

- by Daniel

Hi all, I am working on a RedHat server along with several other users. We use the batch utility to set a job queue. Some of the programs that I use write stuff to stdout during the run, with info on who much data has been processed to far and estimated time until completion etc. batch -q z at> myScript -i somefile -o someotherfile By default, the batch util send an email to me (since I configured it using .forward) with the entire output from stdout. Since the scripts writes something to stdout a few times each second, the amount of log-stuff I get from a two-day script can be ˜20 Mbs. Clearly not what I want. I can of course pipe stdout to a file like so batch -q z at> myScript -i somefile -o someotherfile > myscript.stdout.log but then I get a blank e-mail from the util. So to my question: Is it possible to configure batch so that it sends time the job started and ended, or run time or some oth valuable information to me, instead of a 20 Mb mail or a blank mail? Note that the scripts that I use are binaries and I cannot customize the code to output less info in the first place (which would be the optimal solution I guess). Thanks /Daniel

I know it's an elementary problem, but I can't seem to figure this out. Any help is much appreciated.

Starting CLI application programmatically does not work depending on arguments

- by Daniel Beck

I try to start plink.exe (PuTTY Link, the command line utility/version of PuTTY) from a C# application to establish an SSH reverse tunnel, but it does no longer work as soon as I pass the correct parameters. What does that mean? The following works as expected: it opens a command line window, displays that I forgot to pass the password for the -pw argument quits, and shows the prompt. I know it got the arguments, since it specifically requests the one thing I did not provide. Uri uri = omitted; ProcessStartInfo info = new ProcessStartInfo(); info.FileName = "cmd"; info.Arguments = "/k \"C:\\Program Files (x86)\\PuTTY\\plink.exe\" -R 3389:" + uri.Host + ":" + uri.Port + " -N -l username -pw"; // TODO pwd Process p = Process.Start(info); I tried the same think with calling plink.exe directly instead of cmd.exe /k, but the window closes immediately, which is unfortunate for bug-hunting. BUT when I pass a password in the arguments, plink.exe displays the program help (showing available parameters) and quits: Uri uri = omitted; ProcessStartInfo info = new ProcessStartInfo(); info.FileName = "cmd"; info.Arguments = "/k \"C:\\Program Files (x86)\\PuTTY\\plink.exe\" -R 3389:" + uri.Host + ":" + uri.Port + " -N -l username -pw secretpassword"; Process p = Process.Start(info); No indication of missing parameters. Both the cmd /k and plink.exe variants do not work (the latter closes immediately, so no information regarding different behaviour). When I launch the application from the Windows 7 Start Menu launcher with the identical parameters, it opens a cmd.exe window and establishes the connection as requested. What's wrong? Is there a way plink.exe notices it's not running in a real shell? If yes, how can I circumvent it, like the Start Menu "prompt" does? I hope this question is right on SO, since it, though specifically for a single application, revolves around launching it successfully programmatically.

Troubleshooting a COM+ application deadlock

I'm trying to troubleshoot a COM+ application that deadlocks intermittently. The last time it locked up, I was able to take a usermode dump of the dllhost process and analyze it using WinDbg. After inspecting all the threads and locks, it all boils down to a critical section owned by this thread: ChildEBP RetAddr Args to Child 0deefd00 7c822114 77e6bb08 000004d4 00000000 ntdll!KiFastSystemCallRet 0deefd04 77e6bb08 000004d4 00000000 0deefd48 ntdll!ZwWaitForSingleObject+0xc 0deefd74 77e6ba72 000004d4 00002710 00000000 kernel32!WaitForSingleObjectEx+0xac 0deefd88 75bb22b9 000004d4 00002710 00000000 kernel32!WaitForSingleObject+0x12 0deeffb8 77e660b9 000a5cc0 00000000 00000000 comsvcs!PingThread+0xf6 0deeffec 00000000 75bb21f1 000a5cc0 00000000 kernel32!BaseThreadStart+0x34 The object it's waiting on is an event: 0:016> !handle 4d4 f Handle 000004d4 Type Event Attributes 0 GrantedAccess 0x1f0003: Delete,ReadControl,WriteDac,WriteOwner,Synch QueryState,ModifyState HandleCount 2 PointerCount 4 Name <none> No object specific information available As far as I can tell, the event never gets signaled, causing the thread to hang and hold up several other threads in the process.

Although, I'm still interested in ideas on how I could have figured this out without finding the bug in Oracle's bug database.

Front End Developer v/s PHP-MySQL Engineer

- by user301943

Hello, I want to decide which of this would be a more viable career option? I am ready to quit my current job and hence I am looking for new opportunity. Current job is maintainence and no more active development. My current role is of a PHP/MySQL Developer. I very well understand web-programming and am comfortable with RoR/Sinatra/Zend MVC/JQuery/JSON manipulation, etc. I understand MySQL InnoDB/MyISAM engine and how one differs from the other, etc. Basically, I could very well manage the deployment of a web-application end-to-end including configuration of Apache/Nginx servers, memcache,etc On the other hand, I am being offered a Sr.Front End Web developer that would require me to extensively write HTML/CSS crossbrowser/crossplatform compliant code. I very well understand XHTML/CSS/Box model etc. I would be working on Drupal for the management of websites. While I understand continuing to work on server-side technologies would always be a good career path, how would the role of Core front-end developer turn out to be? If I take this opportunity, will I eventually get a chance to focus onto UCD, HCI, Information Architect,etc. So are these kinda roles possible if I focus on front end development? No offenses to the Front end developers, just want to understand if this is something I want to gain a mastery over. I have 2 yrs of industry experience after graduating with a MS-Computer Science. Although, I have a CS degree, if I were to take uip serious front-end role; I could probably go back and take up some design/HCI/UI courses. Please advise.

I'm doing an XML RPC call in ASP.net with c# and the call returns an Array called userinfo with strings and integers in it and I can't seem to figure out how to parse the data and put it into string and int objects... The only thing that compiles is if I make it an Object in the struct. The int returns fines and is referenced easily. Any help would be appreciated - this is what I got. public Page_Load(object sender, EventArgs e){ IValidateSSO proxy = XmlRpcProxyGen.Create<IValidateSSO>(); UserInfoSSOValue ret2 = proxy.UserInfoSSO(ssoAuth, ssoValue); int i = ret2.isonid; } public struct UserInfoSSOValue { public Object userinfo; public int isonid; } [XmlRpcUrl("host")] public interface IValidateSSO : IXmlRpcProxy { [XmlRpcMethod("sso.session_userinfo")] UserInfoSSOValue UserInfoSSO(string ssoauth, string sid); } Here is what the xml rpc calls returns (I know it's in php... I'm trying to implement in c#): sso.session_userinfo(string $ssoauth, string $sid) string $ssoauth - authentication string (assigned by ONID support) string $sid - sid to get info on Returns: Array ( [userinfo] => Array ( [lastname] => College [expire_time] => 1118688011 [osuuid] => 12345678901 [sid_length] => 3600 [ip] => 10.0.0.1 [sid] => WiT7ppAEUKS3rJ2lNz3Ue64sGPxnnLL0 [username] => collegej [firstname] => Joe [fullname] => College, Joe Student [email] => [email protected] [create_time] => 1118684410 ) [isonid] => 1 ) array userinfo - array containing basic user information

WPF MVVM Chart change axes

- by c0uchm0nster

I'm new to WPF and MVVM. I'm struggling to determine the best way to change the view of a chart. That is, initially a chart might have the axes: X - ID, Y - Length, and then after the user changes the view (either via lisbox, radiobutton, etc) the chart would display the information: X - Length, Y - ID, and after a third change by the user it might display new content: X - ID, Y - Quality. My initial thought was that the best way to do this would be to change the bindings themselves. But I don't know how tell a control in XAML to bind using a Binding object in the ViewModel, or whether it's safe to change that binding in runtime? Then I thought maybe I could just have a generic Model that has members X and Y and populate them as needed in the viewmodel? My last thought was that I could have 3 different chart controls and just hide and show them as appropriate. What is the CORRECT/SUGGESTED way to do this in the MVVM pattern? Any code examples would be greatly appreciated. Thanks

Calculate time of method execution and send to WCF service async

- by Tim

I need to implement time calculation for repository methods in my asp .net mvc project classes. The problem is that i need to send time calculation data to WCF Service which is time consuming. I think about threads which can help to cal WCF service asynchronously. But I have very little experience with it. Do I need to create new thread each time or I can create a global thread, if so then how? I have something like that: StopWatch class public class StopWatch { private DateTime _startTime; private DateTime _endTime; public void Start() { _startTime = DateTime.Now; } protected void StopTimerAndWriteStatistics() { _endTime = DateTime.Now; TimeSpan timeResult = _endTime - _startTime; //WCF proxy object var reporting = AppServerUtility.GetProxy<IReporting>(); //Send data to server reporting.WriteStatistics(_startTime, _endTime, timeResult, "some information"); } public void Stop() { //Here is the thread I have question with var thread = new Thread(StopTimerAndWriteStatistics); thread.Start(); } } Using of StopWatch class in Repository public class SomeRepository { public List<ObjectInfo> List() { StopWatch sw = new StopWatch(); sw.Start(); //performing long time operation sw.Stop(); } } What am I doing wrong with threads?

Robot Simulation in Java

- by Eddy Freeman

Hi Guys, I am doing a project concerning robot simulation and i need help. I have to simulate the activities of a robot in a warehouse. I am using mindstorm robots and lego's for the warehouse. The point here is i have to simulate all the activities of the robot on a Java GUI. That is whenever the robot is moving, users have to see it on the GUI a moving object which represents the robot. When the roads/rails/crossings of the warehouse changes it must also be changed on the screen. The whole project is i have to simulate whatever the robot is doing in the warehouse in real-time. Everything must happen in real-time I am asking which libraries in Java i can use to do this simulations in real-time and if someone can also point me to any site for good information. Am asking for libraries in Java that i can use to visualize the simulation in real-time. All suggestions are welcome. Thanks for your help.

Crystal reports 11 RDC (COM API) displays printer dialog even when I tell it not to prompt

- by bdonlan

I'm using Crystal Reports 11's RDC (COM) API to print. My code looks like this: HRESULT res = m_Report->SelectPrinter(b_driver, b_device, b_port); if (FAILED(res)) return res; // For these calls, the #import wrapper throws on error m_Report->PutPrinterDuplex(dmDuplex); m_Report->PutPaperSize(dmPaperSize); m_Report->PutPaperSource((CRPaperSource)pdlg->GetDevMode()->dmDefaultSource); if (m_Report->GetPaperOrientation() == crDefaultPaperOrientation) m_Report->PutPaperOrientation(crPortrait); VARIANT vfalse; VariantInit(&vfalse); vfalse.vt=VT_BOOL; vfalse.boolVal=0; res = m_Report->PrintOut(vfalse); However, at the end of all this, crystal reports still shows its own printer selection dialog - but only for some reports, it seems. Why does crystal reports show a print dialog even when I pass false for promptUser? And how, then, can I suppress crystal reports' internal printer selection dialog and force it to use my values? Edit: Whoops, CR11, not CR9. Some further information: The reports that work properly (ie, do not show the print dialog) are generated internally using the RDC API; we create a new report object, import subreports into it, then print the result. No problem there. The reports that do not work properly (ie, force the print dialog to open) have been created with a previous version of crystal reports; however, opening and saving the report does not seem to help. Sample reports in the Crystal Reports installation directory show the same problem. I tried reproducing with VBScript; however, the result was that nothing was printed at all (no dialog, no nothing): Set app = CreateObject("CrystalRuntime.Application.11") Set report = app.OpenReport("C:\Program Files\Business Objects\Crystal Reports 11.5\Samples\en\Reports\General Business\Inventory Crosstab.rpt") report.PrintOut(True) rem Testing with a True parameter to force a print dialog - but no printout and nothing appears (no error either though)

asp.net mvc cookies not being sent back

- by brian b

My application at mysubdomain.mydomain.com needs to set a cookie that contains some user session information. They log in at a https page. We authenticate them and set some session info in a cookie. We do this in a helper library that takes in the controller context contextBase.Response.Cookies[CookiePayload.CookieName].Value = encryptedTicket; contextBase.Response.Cookies[CookiePayload.CookieName].Expires = cookieExpires; contextBase.Response.Cookies[CookiePayload.CookieName].Domain= ConfigHelper.CookieDomain; contextBase.Response.Cookies[CookiePayload.CookieName].HttpOnly=true; We do a quick redirect in the controller (to a non https page): this.ControllerContext.HttpContext.Response.Redirect(redirectTo, false); return null; The cookie appears in the response (according to firebug's net tab). But neither fireforx nor ie send the cookie on subsequent gets. We are setting the cookie domain to mydomain.com even though the site is mysubdomain.mydomain.com. Skipping the redirect command has no effect, nor does changing the cookie value. I'm baffled. Thanks for any suggestions.

Setting Path and Expiration for session cookie in asp.net

- by Sergej Andrejev

Anything I have tried didn't work. Currenly I have following code to change asp.net session cookie expiration date and path, but asp doesn't want to listen to me. I sends same cookie in Set-Cookie header two times sometimes, sometimes it sends it's default cookie ignoring path and expiration date, sometimes it sends everything as expected, and sometimes it doesn't send Set-Cookie at all. What should I do. This drives me nuts :( My code in Global.asax protected void Application_PreRequestHandlerExecute(Object sender, EventArgs e) { /// only apply session cookie persistence to requests requiring session information if (Context.Handler is IRequiresSessionState || Context.Handler is IReadOnlySessionState) { var sessionState = ConfigurationManager.GetSection("system.web/sessionState") as SessionStateSection; var cookieName = sessionState != null && !string.IsNullOrEmpty(sessionState.CookieName) ? sessionState.CookieName : "ASP.NET_SessionId"; var timeout = sessionState != null ? sessionState.Timeout : TimeSpan.FromMinutes(20); /// Ensure ASP.NET Session Cookies are accessible throughout the subdomains. if (Request.Cookies[cookieName] != null && Session != null && Session.SessionID != null) { Response.Cookies[cookieName].Value = Session.SessionID; Response.Cookies[cookieName].Path = Request.ApplicationPath; Response.Cookies[cookieName].Expires = DateTime.Now.Add(timeout); } } }
