  • Why does grails use hsqldb when I ask for mysql?

    - by John
    I'm following the racetrack example from Jason Rudolph's book at InfoQ, using grails-1.2.1. I got up to the part where I was to switch from hsqldb to mysql. I think I've deleted every reference to hsqldb in the DataSource.groovy file, but I get an exception and the stack trace shows it's still using hsqldb. DataSource.groovy dataSource { boolean pooled = true String driverClassName = "com.mysql.jdbc.Driver" String url = "jdbc:mysql://localhost/dfpc2" String dbCreate = "create" String username = "dfpc2" String password = "dfpc2" dialect = org.hibernate.dialect.MySQL5InnoDBDialect } hibernate { cache.use_second_level_cache=true cache.use_query_cache=true cache.provider_class='net.sf.ehcache.hibernate.EhCacheProvider' } // environment specific settings environments { development { } test { } production { } } When I grails run-app it all starts up with no errors. I can navigate to the home page. But when I click on one of the links, I get a stack trace: java.sql.SQLException: Table not found in statement [select this_.id as id0_0_, this_.version as version0_0_, this_.name as name0_0_, this_.variant as variant0_0_ from domainObject this_ limit ?] at org.hsqldb.jdbc.Util.throwError(Unknown Source) at org.hsqldb.jdbc.jdbcPreparedStatement.<init>(Unknown Source) at org.hsqldb.jdbc.jdbcConnection.prepareStatement(Unknown Source) at dfpc2.domainObjectController$_closure2.doCall(script1269434425504953491149.groovy:13) at dfpc2.domainObjectController$_closure2.doCall(script1269434425504953491149.groovy) at java.lang.Thread.run(Thread.java:619) My mysql database shows no tables created. (I don't think groovy's connected to mysql yet.) Things I've checked: mysql-connector-java-5.1.6.jar is in lib directory. I've tried grails clean I tried putting the dataSource info in the development environment (I haven't graduated to test or prod yet), but it seemed to make no difference. The stdout shows I'm using development env. I've googled for solutions, but the only solution I've found is when people don't change the test or production environments.

  • Jquery Sorting by Letter

    - by Batfan
    I am using jquery to sort through a group of paragraph tags (kudos to Aaron Harun). It pulls the value "letter" (a letter) from the url string and displays only paragraphs that start with that letter. It hides all others and also consolidates the list so that there are no duplicates showing. See the code: var letter = '<?php echo(strlen($_GET['letter']) == 1) ? $_GET['letter'] : ''; ?>' function finish(){ var found_first = []; jQuery('p').each(function(){ if(jQuery(this).text().substr(0,1).toUpperCase() == letter){ if(found_first[jQuery(this).text()] != true){ jQuery(this).addClass('current-series'); found_first[jQuery(this).text()] = true; }else{ jQuery(this).hide(); } } else{ jQuery(this).hide();} }) } Been working with this all day and I have 2 Questions on this: Is there a way to get it to ignore the word 'The', if it's first? For example, if a paragraph starts with 'The Amazing', I would like it to show up on the 'A' page, not the 'T' page, like it currently is. Is there a way to have a single page for (all) numbers? For example, the url to the page would be something similar to domain.com/index.php?letter=0 and this would show only the paragraph tags that start with a number, any number. I can currently do this with single numbers but, I would like 1 page for all numbers.

  • Arduino variable going blank after the first pass

    - by user541597
    I have an Arduino sketch that takes a timet and when that timet is equal to the current time it sets the new timet to timet + 2. For example: char* convert(char* x, String y) { int hour; int minute; sscanf(x, "%d:%d", &hour, &minute); char buf[6]; if (y == "6") { if (hour > 17) { hour = (hour+6)%24; snprintf(buf, 10, "%d:%d", hour, minute ); } else if (hour < 18) { //hour = hour + 6; minute = (minute + 2); snprintf(buf, 10, "%d:%d", hour, minute); } } if (y == "12") { if (hour > 11) { hour = (hour+12)%24; snprintf(buf, 10, "%d:%d", hour, minute ); } else if (hour < 12) { hour = hour + 12; snprintf(buf, 10, "%d:%d", hour, minute); } } if (y == "24") { hour = (hour+24)%24; snprintf(buf, 10, "%d:%d", hour, minute ); } return buf; } The sketch starts for example at 1:00am. timet is set to 1:02, at system time 1:02 timet is equal to the system time. My loops looks like this: if (timet == currenttime) { timet = convert(timet) } Whenever I check the value of timet it should equal 1:04, however I get the correct value at the first run after the execution of convert, however every time after that my timet value is blank. I tried changing the code instead of using the if loop. I only run the convert function when I send for example t through the serial monitor. This works fine and outputs the correct timet after the execution of the convert function, So I figured the problem is in the if loop... Any ideas?

  • we would like the user to be able to pick a file from native file system and drag & drop it to our a

    - by user261740
    We have an existing java desktop application which starts, when user click on our application icon (placed on desktop) OR double click on executable(.exe). It opens the frame which allows user to select the file from native file system and uploads it to the server. Now we would like to facilitate user, that he can pick a file from windows explorer and drag it to the "shortcut / Application icon" & drop it on the "shortcut / Application icon" on the desktop. This would start the uploading of that file on the server. we need to capture the action of "drop" and launch on shortcut.. which may be completely not related to java, it can be very generic to any application. We are using JSmooth to build an executable from jar and NSIS for installer purpose. I would like to know.. How we can launch the application if user drops local file onto the system icon ? How we get the absolute path of file name which has been dropped onto the executable ?

  • Looping through Markers with Google Maps API v3 Problem

    - by Oscar Godson
    I'm not sure why this isn't working. I don't have any errors, but what happens is, no matter what marker I click on, it clicks the 3rd one (which is the last one out of 4 markers. Array starts at 0, obviously) and shows the number "3", which is correct for THAT one, but I'm not clicking that one. Here is most of my code, just not the array of [place-name, coordinates] (var locations, which you will see): function initialize() { var latlng = new google.maps.LatLng(45.522015,-122.683811); var settings = { zoom: 15, center: latlng, disableDefaultUI:true, mapTypeId: google.maps.MapTypeId.SATELLITE }; var map = new google.maps.Map(document.getElementById("map_canvas"), settings); var infowindow = new Array(); var marker = new Array(); for(x in locations){ console.log(x); infowindow[x] = new google.maps.InfoWindow({content: x}); marker[x] = new google.maps.Marker({title:locations[x][0],map:map,position:locations[x][1]}); google.maps.event.addListener(marker[x], 'click', function() {infowindow[x].open(map,marker[x]);}); } } initialize() The console.log output is (its correct, and what i expect): 0 1 2 3 So, any ideas?

  • application trying to connect to mirrored sql db

    - by hp
    Hello, We have 4 web servers that host our asp.net (3.5) application. Randomly, we get error messages like : 1) "Login failed for user 'userid'" 2) "A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)" we are running sql2005 and have a principle and a mirror db (sync). When these exceptions are thrown, I look at the SQL error logs on the mirrored db and noticed the failed login messages in there. The principle db is running fine and the other web apps are working great. this will happen for maybe 10 min, then the app pool recycles and it starts hitting the principle db again. Is there a configuration I have incorrect? my theory is that our principle db is forwarding the request to the mirror, but that should never happen. any help??

  • Monotouch or Titanium for rapid application development on IPhone?

    - by Ronnie
    As a .Net developer I always dreamed for the possibility to develop with my existing skills (c#) applications for the Iphone. Both programs require a Mac and the Iphone Sdk installed. Appcelerator Titanium was the first app I tried and it is based on exposing some Iphone native api to javascript so that they can be called using that language. Monotouch starts at $399 for beeing able to deploy on the Iphone and not on the Iphone simulator while Titanium is free. Monotouch (Monodevelop) has an Ide that is currently missing in Titanium (but you can use any editor like Textmate, Aptana...) I think both program generate at the end a native precompiled app (also if I am not sure about the size of the final app on the Iphone as I think the .Net framework calls are prelilnked at compilation time in Monotouch). I am also not sure about the full coverage of all the Iphone api and features. Titanium has also the advantage to enable Android app development but as a c# developer I still find Monotouch experience more like the Visual Studio one. Which one would you choose and what are your experiences on Monotouch and Titanium?

  • Change default java installation

    - by user1501700
    I have many Java versions installed on a Windows 7 machine. Some of them are 32 bits, some are 64 bits. Now as default it starts one of those last versions (1.7 64 bits). How do I tell my Windows 7 machine to use another version of Java? One of the reasons is that I'm developing a JNI project from Microsoft Visual Studio C++ - it uses also java 1.7 64 bits. Best regards, Andrej I have set: User variable: JAVA_HOME=C:\j2sdk1.4.2_04 PATH=%JAVA_HOME%\bin;%PATH% and system variable: JAVA_HOME=C:\j2sdk1.4.2_04 PATH=...a_lot_of_paths...;%JAVA_HOME%\bin;%PATH% I had no idea which is better to set - for user or system settings. Done both. System restart. And...it didn't helped :( When I run "java -version" from cmd i have java 1.7, but not java 1.4 like defined in PATH. after run C:where java I got two results: C:\Windows\System32\java.exe C:\j2sdk1.4.2_04\bin\java.exe Who let Java go to my windows directory ???!!! How to deal with that?

  • Using WIndows PowerShell 1.0 or 2.0 to evaluate performance of executable files.

    - by Andry
    Hello! I am writing a simple script on Windows PowerShell in order to evaluate performance of executable files. The important hypothesisi is the following: I have an executable file, it can be an application written in any possible language (.net and not, Viual-Prolog, C++, C, everything that can be compiled as an .exe file). I want to profile it getting execution times. I did this: Function Time-It { Param ([string]$ProgramPath, [string]$Arguments) $Watch = New-Object System.Diagnostics.Stopwatch $NsecPerTick = (1000 * 1000 * 1000) / [System.Diagnostics.Stopwatch]::Frequency Write-Output "Stopwatch created! NSecPerTick = $NsecPerTick" $Watch.Start() # Starts the timer [System.Diagnostics.Process]::Start($ProgramPath, $Arguments) $Watch.Stop() # Stops the timer # Collectiong timings $Ticks = $Watch.ElapsedTicks $NSecs = $Watch.ElapsedTicks * $NsecPerTick Write-Output "Program executed: time is: $Nsecs ns ($Ticks ticks)" } This function uses stopwatch. Well, the functoin accepts a program path, the stopwatch is started, the program run and the stopwatch then stopped. Problem: the System.Diagnostics.Process.Start is asynchronous and the next instruction (watch stopped) is not executed when the application finishes. A new process is created... I need to stop the timer once the program ends. I thought about the Process class, thicking it held some info regarding the execution times... not lucky... How to solve this?

  • Javascript to fire event when a key pressed on the Ajax Toolkit Combo box.

    - by Paul Chapman
    I have the following drop down list which is using the Ajax Toolkit to provide a combo box <cc1:ComboBox ID="txtDrug" runat="server" style="font-size:8pt; width:267px;" Font-Size="8pt" DropDownStyle="DropDownList" AutoCompleteMode="SuggestAppend" AutoPostBack="True" ontextchanged="txtDrug_TextChanged" /> Now I need to load this up with approx 7,000 records which takes a considerable time, and effects the response times when the page is posted back and forth. The code which loads these records is as follows; dtDrugs = wsHelper.spGetAllDrugs(); txtDrug.DataValueField = "pkDrugsID"; txtDrug.DataTextField = "drugName"; txtDrug.DataSource = dtDrugs; txtDrug.DataBind(); However if I could get an event to fire when a letter is typed instead of having to load 7000 records it is reduced to less than 50 in most instances. I think this can be done in Javascript. So the question is how can I get an event to fire such that when the form starts there is nothing in the drop down, but as soon as a key is pressed it searches for those records starting with that letter. The .Net side of things I'm sure about - it is the Javascript I'm not. Thanks in advance

  • Adobe Air update error "file version doesn't match" but it's the same!...

    - by baroquedub
    I'm using Claus Wahlers' AIR Remote Updater class (codeazur.com.br/lab/airremoteupdater/). All works fine and an update is triggered if the remote version is newer. The newer file is downloaded and the update starts. However I then get "an error has occured" message: "This application cannot be installed because this installer has been mis-configured" (The same file will update without errors when run manually "Would you like to replace the currently installed version?" Choosing 'replace' works fine) I have enabled Air Application Installer logging and I can see that both the app id and the pub id match - this seems to be a common reason for this problem (forums.adobe.com/thread/243421?tstart=60) The error given in the log file is as follows: AIR file version doesn't match Requested version: ; AIR file version: 1.0.2 But if I unzip the new app file and look at META-INF\AIR\application.xml the version designator shows <version>1.0.2</version> As requested! The log file is also showing me where the newer file is being downloaded and unpacked. If I look at the application.xml file in that directory: Unpackaging to C:\Documents and Settings\myusername\Local Settings\Temp\fla893D.tmp the version designator also shows <version>1.0.2</version> I don't get it?! The log tells me that the requested file version doesn't match but it's exactly the same as what's shown in the version designator of the downloaded update package... This is driving me crazy. Can anyone help?

  • Why would an OS X bundle take about 30 seconds to open?

    - by Aftermathew
    Hi, We wrote a simple OS X executable in objective c. It opens and runs very quickly when called. We then put that executable into a .app bundle. When calling "open" from the command line on that bundle, or double clicking the app from the finder the "open" call can take upwards of 30 seconds to return. This is especially confusing because "open" clearly starts the executable right away (I can see it running in the process list right away, and have other indications that it's doing work), but when done from the command line, the "open" command takes a long time to return, and when done from the Finder the icon will bounce for a very long time before acting normal. I know the executable itself still opens very quickly because calling "open" on the executable inside my bundle returns very quickly, however calling it on the .app runs the code right away but takes 30 seconds or so to return. Has anyone run into this before? Do you have any suggestions for what could cause something like this? I've not been able to see anything funny in the bundle structure or the plist, but maybe I'm missing something. Thanks,

  • Is this possible: JPA/Hibernate query with list property in result ?

    - by Kdeveloper
    In hibernate I want to run this JPQL / HQL query: select new org.test.userDTO( u.id, u.name, u.securityRoles) FROM User u WHERE u.name = :name userDTO class: public class UserDTO { private Integer id; private String name; private List<SecurityRole> securityRoles; public UserDTO(Integer id, String name, List<SecurityRole> securityRoles) { this.id = id; this.name = name; this.securityRoles = securityRoles; } ...getters and setters... } User Entity: @Entity public class User { @id private Integer id; private String name; @ManyToMany @JoinTable(name = "user_has_role", joinColumns = { @JoinColumn(name = "user_id") }, inverseJoinColumns = {@JoinColumn(name = "security_role_id") } ) private List<SecurityRole> securityRoles; ...getters and setters... } But when Hibernate 3.5 (JPA 2) starts I get this error: org.hibernate.hql.ast.QuerySyntaxException: Unable to locate appropriate constructor on class [org.test.UserDTO] [SELECT NEW org.test.UserDTO (u.id, u.name, u.securityRoles) FROM nl.test.User u WHERE u.name = :name ] Is a select that includes a list as a result not possible? Should I just create 2 seperate queries?

  • C++ socket concurrent server

    - by gregpi
    Hi all; Im writing a concurrent server that's supposed to have a communication channel and a data channel. The client initially connect to the communication channel to authenticate, upon successful authentication, the client is then connected to the data channel to access data. My program is already doing that, and im using threads.My only issue is that if I try to connect another client, I get a "cannot bind : address already in use" error. I have it this way: PART A Client connect to port 4567 (and enter his login info). A thread spawn to handle the client(repeated for each client that connects). In the thread created, I have a function(let's call it FUNC_A) that checks the client's login info(dont worry about how the check is done), if successful, the thread starts the data server(listening on 8976) then sends an OK to the client, once received the client attempts to connect to the data server. PART B Once a client connect to the data server, from inside FUNC_A the client is accepted and another thread is spawn to handle the client's connection to the data server.(hopefully everything is clear). Now, all that is working fine. However, if I try to connect with second client when it gets to PART B I get a "cannot bind error: address already in use". I've tried so many different ways, I've even tried spawning a thread to start the data server and accept the client and then start another thread to handle that connection. still no luck. Please give me a suggestion as to what I'm doing wrong, how do I go about doing this or what's the best way to implement it. Thank you

  • Cant display button on specific rows of UITableView properly for iPhone

    - by varunwg
    Hi, I am trying to have a button for selected rows of my table. Here is the example code I am using: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *ControlRowIdentifier = @"ControlRowIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:ControlRowIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:ControlRowIdentifier] autorelease]; } if ([indexPath row] > 5) { UIImage *buttonUpImage = [UIImage imageNamed:@"button_up.png"]; UIImage *buttonDownImage = [UIImage imageNamed:@"button_down.png"]; UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(0.0, 0.0, buttonUpImage.size.width, buttonUpImage.size.height); [button setBackgroundImage:buttonUpImage forState:UIControlStateNormal]; [button setBackgroundImage:buttonDownImage forState:UIControlStateHighlighted]; [button setTitle:@"Tap" forState:UIControlStateNormal]; [button addTarget:self action:@selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside]; cell.accessoryView = button; } NSUInteger row = [indexPath row]; NSString *rowTitle = [list objectAtIndex:row]; cell.textLabel.text = rowTitle; return cell; } This code works absolutely fine when loaded for 1st time. So, as per the logic it shows 'Tap' button for all rows greater than 5. Problem occurs when I scroll up and down. Once I do that it just starts putting that button at any random row. I dont understand why it does that and it'll be really helpful if someone can give some tips on this. Thanks.

  • Timer appears to be pausing when screen becomes inactive

    - by elchuppa
    So I have a very simple android activity that starts a timer when you hit a button. Timer timer = new Timer(); timer.schedule(new TimerTask() { @Override public void run() { doStuff(); } }, 15 * 60 * 1000); So this worked reasonably well for me when I was testing but as it turns out when the screen becomes inactive so does the timer. I was a bit surprised by this. I understand you need to create a service to have anything running in the background but I hadn't realized this is required for an activity in the foreground when the phone has inactivated the screen due to lack of activity. What confuses me is I think this worked as I expected originally and just in the last few weeks or so has the timer been affected by the phone saving power. I could be wrong though.. So basically my questions are: am I seeing expected behavior? Do I need to create all timers as services or somehow disallow powersaving? thanks for any advice, Patrick

But as I have mentioned, I forbid activity recreation for basic events. So any suggestions are very appreciated.

  • PEAR:DB connection parameters

    - by Markus Ossi
    I just finished my first PHP site and now I have a security-related question. I used PEAR:DB for the database connection and made a separate parameter file for it. How should I hide this parameter file? I found a guide (http://www.kitebird.com/articles/peardb.html) that says: Another way to specify connection parameters is to put them in a separate file that you reference from your main script. ... It also enables you to move the parameter file outside of the web server's document tree, which prevents its contents from being displayed literally if the server becomes misconfigured and starts serving PHP scripts as plain text. I have now put my file in a directory like this /include/db_parameters.inc However, if I go to this URL, the web server shows me the contents of the file including my database username and password. From what I've understood, I should protect this file so, that even though PHP would be served as text, nobody could read this. What does outside of web server's document tree mean here? Put the PHP file out of public_html directory altogether deeper into the server file system? Some CHMOD?

  • Touch draw in Quatz 2D/Core Graphics

    - by OgreSwamp
    Hello, I'm trying to implement "hand draw tool". At the moment algorythm looks like that (I don't insert any code because methods are quite big, will try to explain an idea): Drawing In touchesStarted: method I create NSMutableArray *pointsArray and add point into it. Call setNeedsDisplay: method. In touchesMoved: method I calculate points between last added point from the pointsArray and current point. Add all points to the pointsArray. Call setNeedsDisplay: method. In touchesFinished: event I calculate points between last added point from the array and current point. Set flag touchesWereFinished. Call setNeedsDisplay:. Render: drawRect: method checks is pointsArray != nil and is there any data in it. If there is - it starts to traw circles in each point of this array. If flag touchesWereFinished is set - save current context to the UIImage, release pointsArray, set it to nil and reset the flag. There are a lot disadvantages of this method: It is slow It becomes extremely slow when user touches and move finger for long time. Array becomes enormous "Lines" composed by circles are ugly I would like to change my algorithm to make it bit faster and line smoother. In result I would like to have lines like on the picture at following URL (sorry, not enough reputation to insert an image): http://2.bp.blogspot.com/_r5VzEAUYXJ4/SrOYp8tJCPI/AAAAAAAAAMw/ZwDKXiHlhV0/s320/SketchBook+Mobile(4).png Can you advice me, ho I can draw lines this way (smooth and slim on the edges)? I thought to draw circles with alpha gradient on the edges (to make lines smoother), but it will be extremely slowly IMHO. Thanks for help

  • Splitting 25mb .txt file into smaller files using text delimiter

    - by user574141
    Regards, SO I am new to python and Perl. I have been trying to solve a simple problem and getting tied in knots with syntax. I hope someone has the time and patience to help. I have a 25mb file in ".txt" format which contains news-wire articles going back to 1970. Each news story is concatenated to the next, with only the "Copyright" statement to delimit. Each news story starts with "Item XX of XXX DOCUMENTS". There are certain metadata that are repeated throughout, I will use these for tagging later on. I wish to split this 25mb file into separate .txt files, each containing one news story (i.e. the text between "DOCUMENTS" and "Copyright", saving each with a different name (obviously). I am trying to 1 ) open the file... 2) iterate over lines in the file checking for the eof delimiter, and if it is not present writing the line to a list 3)write that list to a seperate small file. I'm having big problems with changing filenames using the counter, and how do I make Python start from where I left off, is the "seek" function appropriate? so far I have been trying this approach, completely unsuccessfully: myfile = open ("myfile.txt", 'r') filenumber = 0 for line in myfile.readline(): filenumber += 1 w=0 while myfile.readline() != '\s+DOCUMENTS\s*\n' ### read my line into a list mysmallfile()['w'] = [myfile.readline()] w += 1 output = open('C:\\Users\\dunner7\\Documents\###how do I change the filename each iteration???', 'w') output.writelines(mysmallfile) ###go back to start. Thank you for your time and patience. RD

  • JavaScript change to DropDownList.SelectedIndex not submitted

    - by Bellfalasch
    Hi So, I have a form to submit fighters. You write his/her name, country, and then the team they fight for + the team's country. When you start typing the name I have constructed my own Ajax AutoCompleter. It will find existing fighters that might match. When you click on one of the suggestions it will populate up to four fields depending on existing data in the database. If you're lucky the fighter already exists with information on country, team, and the team's country. The problems starts when submitting. The JavaScript follows and just get's the id of the country to select (also the value of the select-option), and the select-element itself. function dropdownSelect(value, element) { var dropdown = document.getElementById(element); for (var i = 0; i < dropdown.options.length; i++) { if (dropdown.options[i].value == value) { dropdown.options[i].selected = true; return true; } } } When submitting the ASP.NET-code halt's and says that my country-field is null. So my JavaScript-change of selected field couldn't be read by ASP.NET. Is this a limitation of how ASP.NET works? Or a limitation of my skills? ;P

  • entity framework insert bug

    - by tmfkmoney
    I found a previous question which seemed related but there's no resolution and it's 5 months old so I've opened my own version. http://stackoverflow.com/questions/1545583/entity-framework-inserting-new-entity-via-objectcontext-does-not-use-existing-e When I insert records into my database with the following it works fine for a while and then eventually it starts inserting null values in the referenced field. This typically happens after I do an update on my model from the database although not always after I do an update. I'm using a MySQL database for this. I have debugged the code and the values are being set properly before the save event. They're just not getting inserted properly. I can always fix this issue by re-creating the model without touching any of my code. I have to recreate the entire model, though. I can't just dump the relevant tables and re-add them. This makes me think it doesn't have anything to do with my code but something with the entity framework. Does anyone else have this problem and/or solved it? using (var db = new MyModel()) { var stocks = from record in query let ticker = record.Ticker select new { company = db.Companies.FirstOrDefault(c => c.ticker == ticker), price = Convert.ToDecimal(record.Price), date_stamp = Convert.ToDateTime(record.DateTime) }; foreach (var stock in stocks) { if (stock.company != null) { var price = new StockPrice { Company = stock.company, price = stock.price, date_stamp = stock.date_stamp }; db.AddToStockPrices(price); } } db.SaveChanges(); }

  • Stopping work from one thread using another thread

    - by 113483626144458436514
    Not sure if my title is worded well, but whatever :) I have two threads: the main thread with the work that needs to be done, and a worker thread that contains a form with a progress bar and a cancel button. In normal code, it would be the other way around, but I can't do that in this case. When the user clicks the cancel button, a prompt is displayed asking if he wants to really cancel the work. The problem is that work continues on the main thread. I can get the main thread to stop work and such, but I would like for it to stop doing work when he clicks "Yes" on the prompt. Example: // Main thread work starts here t1 = new Thread(new ThreadStart(progressForm_Start)); t1.Start(); // Working for (i = 0; i <= 10000; i++) { semaphore.WaitOne(); if (pBar.Running) bgworker_ProgressChanged(i); semaphore.Release(); if (pBar.IsCancelled) break; } t1.Abort(); // Main thread work ends here // Start progress bar form in another thread void progressForm_Start() { pBar.Status("Starting"); pBar.ShowDialog(); } I could theoretically include a prompt in the cancelWatch() function, but then I would have to do that everywhere I'm implementing this class.
