  • Setting Background of a Jbutton

    - by mithun1538
    Hello there, I have 5 JButtons: b1, b2, b3, b4, b5. By default, their color is gray. When I click on any button, the background of that button changes to white. When I click another button, I want that previous clicked button to change its background to gray, and this newly clicked button to change its background to white. Here is the code that I wrote: int liveButton = 0; //holds the value of the button that is last clicked. //0 indicates no button clicked (in the beginning) private void ChangeInUsersList(int clickedButton) { switch(liveButton) { case 1 : b1.setBackground(Color.GRAY); break; case 2 : b2.setBackground(Color.GRAY); break; case 3 : b3.setBackground(Color.GRAY); break; case 4 : b4.setBackground(Color.GRAY); break; case 5 : b5.setBackground(Color.GRAY); break; default: System.out.println("No button to change"); } liveButton = clickedButton;// store the clicked button to change its //background later } private void b1ActionPerformed(java.awt.event.ActionEvent evt) { ChangeInUsersList(1); b1.setBackground(new java.awt.Color(255,255,255)); } private void b2ActionPerformed(java.awt.event.ActionEvent evt) { ChangeInUsersList(2); b2.setBackground(new java.awt.Color(255,255,255)); } private void b3ActionPerformed(java.awt.event.ActionEvent evt) { ChangeInUsersList(3); b3.setBackground(new java.awt.Color(255,255,255)); } private void b4ActionPerformed(java.awt.event.ActionEvent evt) { ChangeInUsersList(4); b4.setBackground(new java.awt.Color(255,255,255)); } private void b5ButtonActionPerformed(java.awt.event.ActionEvent evt) { ChangeInUsersList(5); b5.setBackground(new java.awt.Color(255,255,255)); } However, its not working as expected. When i click on a button, its background does change to white. However, if i click on some other button after that, the former button's background doesnt change to grey. I tried replacing Color.GREY with new java.awt.Color(236,233,216) - the rgb for grey but it still doesnt work.

  • log4net logging problem

    - by Dotnet_user
    Hello everyone, I'm not sure if this is the right forum to post this question. But I'm just hoping someone here might have used log4net in the past, so hoping to get some help. I'm using log4net to log my exceptions. The configuration settings look like this: <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/> </configSections> <log4net debug="false"> <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="C:\Logs\sample.log" /> <appendToFile value="true"/> <rollingStyle value="Size"/> <maxSizeRollBackups value="10"/> <maximumFileSize value="10MB"/> <staticLogFileName value="true"/> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%-5level %date %logger.%method[line %line] - %message%newline"/> </layout> </appender> <root> <level value="INFO"/> <appender-ref ref="RollingLogFileAppender"/> </root> </log4net> </configuration> I started out by adding this configuration to web.config, but I got an error (VS studio could not find a schema for log4net-"Could not find schema information for the element log4net"). So I followed this link (http://stackoverflow.com/questions/174430/log4net-could-not-find-schema-information-messages) and configured my settings in a separate xml file and added the following line of code in my AssemblyInfo.cs: [assembly: log4net.Config.XmlConfigurator(ConfigFile = "xmlfile.xml", Watch = true)] And in the actual code, I placed this line: public void CreateUser(String username, String password) { try { log.Info("Inside createuser"); //code for creating user } catch(exception e) { log.Info("something happened in create user", e); } } The problem is that the log file is not being created. I can't see anything inside C:\Logs. Can anybody tell me what I'm doing wrong here? Any suggestions/inputs will be very helpful. Thank you all in advance.

  • JSON Post To Rails From Android

    - by Stealthnh
    I'm currently working on an android app that interfaces with a Ruby on Rails app through XML and JSON. I can currently pull all my posts from my website through XML but I can't seem to post via JSON. My app currently builds a JSON object from a form that looks a little something like this: { "post": { "other_param": "1", "post_content": "Blah blah blah" } } On my server I believe the Create method in my Posts Controller is set up correctly: def create @post = current_user.posts.build(params[:post]) respond_to do |format| if @post.save format.html { redirect_to @post, notice: 'Post was successfully created.' } format.json { render json: @post, status: :created, location: @post } format.xml { render xml: @post, status: :created, location: @post } else format.html { render action: "new" } format.json { render json: @post.errors, status: :unprocessable_entity } format.xml { render xml: @post.errors, status: :unprocessable_entity } end end end And in my android app I have a method that takes that JSON Object I posted earlier as a parameter along with the username and password for being authenticated (Authentication is working I've tested it, and yes Simple HTTP authentication is probably not the best choice but its a quick and dirty fix) and it then sends the JSON Object through HTTP POST to the rails server. This is that method: public static void sendPost(JSONObject post, String email, String password) { DefaultHttpClient client = new DefaultHttpClient(); client.getCredentialsProvider().setCredentials(new AuthScope(null,-1), new UsernamePasswordCredentials(email,password)); HttpPost httpPost = new HttpPost("http://mysite.com/posts"); JSONObject holder = new JSONObject(); try { holder.put("post", post); StringEntity se = new StringEntity(holder.toString()); Log.d("SendPostHTTP", holder.toString()); httpPost.setEntity(se); httpPost.setHeader("Content-Type","application/json"); } catch (UnsupportedEncodingException e) { Log.e("Error",""+e); e.printStackTrace(); } catch (JSONException js) { js.printStackTrace(); } HttpResponse response = null; try { response = client.execute(httpPost); } catch (ClientProtocolException e) { e.printStackTrace(); Log.e("ClientProtocol",""+e); } catch (IOException e) { e.printStackTrace(); Log.e("IO",""+e); } HttpEntity entity = response.getEntity(); if (entity != null) { try { entity.consumeContent(); } catch (IOException e) { Log.e("IO E",""+e); e.printStackTrace(); } } } Currently when I call this method and pass it the correct JSON Object it doesn't do anything and I have no clue why or how to figure out what is going wrong. Is my JSON still formatted wrong, does there really need to be that holder around the other data? Or do I need to use something other than HTTP POST? Or is this just something on the Rails end? A route or controller that isn't right? I'd be really grateful if someone could point me in the right direction, because I don't know where to go from here.

  • Mootools - how to destroy a class instance

    - by Rob
    What I'm trying to do is create a class that I can quickly attach to links, that will fetch and display a thumbnail preview of the document being linked to. Now, I am focusing on ease of use and portability here, I want to simply add a mouseover event to links like this: <a href="some-document.pdf" onmouseover="new TestClass(this)">Testing</a> I realize there are other ways I can go about this that would solve my issue here, and I may end up having to do that, but right now my goal is to implement this as above. I don't want to manually add a mouseout event to each link, and I don't want code anywhere other than within the class (and the mouseover event creating the class instance). The code: TestClass = new Class({ initialize: function(anchor) { this.anchor = $(anchor); if(!this.anchor) return; if(!window.zzz) window.zzz = 0; this.id = ++window.zzz; this.anchor.addEvent('mouseout', function() { // i need to get a reference to this function this.hide(); }.bind(this)); this.show(); }, show: function() { // TODO: cool web 2.0 stuff here! }, hide: function() { alert(this.id); //this.removeEvent('mouseout', ?); // need reference to the function to remove /*** this works, but what if there are unrelated mouseout events? and the class instance still exists! ***/ //this.anchor.removeEvents('mouseout'); //delete(this); // does not work ! //this = null; // invalid assignment! //this = undefined; // invalid assignment! } }); What currently happens with the above code: 1st time out: alerts 1 2nd time out: alerts 1, 2 3rd time out: alerts 1, 2, 3 etc Desired behavior: 1st time out: alerts 1 2nd time out: alerts 2 3rd time out: alerts 3 etc The problem is, each time I mouse over the link, I'm creating a new class instance and appending a new mouseout event for that instance. The class instance also remains in memory indefinitely. On mouseout I need to remove the mouseout event and destroy the class instance, so on subsequent mouseovers we are starting fresh.

  • Google Maps Rollover Problem in a Flex Website

    - by Laxmidi
    Hi, I'm using Google Maps in my Flex site to create a map. I've got polygons overlayed on the map. When the user rolls over a polygon an infowindow opens identifying the area and the fill Alpha of the area is set to 0. On roll-out, the info window is removed and the fill Alpha is returned to the default, 0.2. The polygons display and the InfoWindow is added and removed correctly. The problem is that the change in fill alpha only occurs on the very last polygon in the list. So for example, if I have polygons A, B, C, and D. If I rollover A, then A's alpha should change. But, instead D's alpha changes. No matter which polygon I rollover, the last polygon's alpha changes. It's weird, because the infoWindows behave correctly on rollover. So, if I rollover polygon A, the correct information for InfoWindow A appears. Please see the code below: private function allEncodedPolygons(event:MouseEvent) : void { var myPaneManager:IPaneManager = map.getPaneManager(); var myMapPane:IPane = myPaneManager.createPane(); if (allHoodsToggle.selected) { map.clearOverlays(); mapType.selectedIndex = -1; for each (var neighbNode:XML in detailMapResultData){ outlinePolygon = this.createPoly(neighbNode); map.addOverlay(outlinePolygon)}; allHoodsToggle.removeEventListener(MouseEvent.CLICK, allEncodedPolygons); } else {myPaneManager.clearOverlays(); allHoodsToggle.removeEventListener(MouseEvent.CLICK, allEncodedPolygons); } } The function below creates the polygons and has the rollover function: private var neighbShapes:Polygon; private function createPoly(neighbNode:XML):Polygon { var optionsDefault:PolygonOptions = new PolygonOptions( { strokeStyle: {thickness: 5, color: 0xFFFF00, alpha: 0.4, pixelHinting: true}, fillStyle: { alpha: 0.2 }} ); var neighbCenterLat:Number = neighbNode.latitudeCenter.toString(); var neighbCenterLong:Number = neighbNode.longitudeCenter.toString(); var neighbCenter:LatLng = new LatLng(neighbCenterLat,neighbCenterLong); var optionsHover:PolygonOptions = new PolygonOptions( { fillStyle: { alpha: 0.0 }} ); var encodedData:EncodedPolylineData = new EncodedPolylineData(neighbNode.encoding.toString(), neighbNode.zoomFactor.toString(), neighbNode.level.toString(), neighbNode.numlevels.toString()); var encodedList:Array = [encodedData]; neighbShapes = Polygon.fromEncoded(encodedList, optionsDefault); neighbShapes.addEventListener(MapMouseEvent.CLICK, function(event:MapMouseEvent): void { map.openInfoWindow(event.latLng, new InfoWindowOptions({content: neighbNode.name.toString(), hasCloseButton:false, hasShadow:true})); }); neighbShapes.addEventListener(MapMouseEvent.ROLL_OVER, function(event:MapMouseEvent): void { neighbShapes.setOptions(optionsHover); map.openInfoWindow(neighbCenter, new InfoWindowOptions({content: neighbNode.name.toString(), hasCloseButton:false, hasShadow:false})); }); neighbShapes.addEventListener(MapMouseEvent.ROLL_OUT, function(event:MapMouseEvent): void { neighbShapes.setOptions(optionsDefault); }); return neighbShapes; } Any suggestions as to why the function that changes the alpha is firing on the last polygon only, even though the InfoWindow appears correctly? If anyone has any ideas, I'd love to hear them. Thanks. -Laxmidi

  • wxPython ListCtrl Column Ignores Specific Fields

    - by g.d.d.c
    I'm rewriting this post to clarify some things and provide a full class definition for the Virtual List I'm having trouble with. The class is defined like so: from wx import ListCtrl, LC_REPORT, LC_VIRTUAL, LC_HRULES, LC_VRULES, \ EVT_LIST_COL_CLICK, EVT_LIST_CACHE_HINT, EVT_LIST_COL_RIGHT_CLICK, \ ImageList, IMAGE_LIST_SMALL, Menu, MenuItem, NewId, ITEM_CHECK, Frame, \ EVT_MENU class VirtualList(ListCtrl): def __init__(self, parent, datasource = None, style = LC_REPORT | LC_VIRTUAL | LC_HRULES | LC_VRULES): ListCtrl.__init__(self, parent, style = style) self.columns = [] self.il = ImageList(16, 16) self.Bind(EVT_LIST_CACHE_HINT, self.CheckCache) self.Bind(EVT_LIST_COL_CLICK, self.OnSort) if datasource is not None: self.datasource = datasource self.Bind(EVT_LIST_COL_RIGHT_CLICK, self.ShowAvailableColumns) self.datasource.list = self self.Populate() def SetDatasource(self, datasource): self.datasource = datasource def CheckCache(self, event): self.datasource.UpdateCache(event.GetCacheFrom(), event.GetCacheTo()) def OnGetItemText(self, item, col): return self.datasource.GetItem(item, self.columns[col]) def OnGetItemImage(self, item): return self.datasource.GetImg(item) def OnSort(self, event): self.datasource.SortByColumn(self.columns[event.Column]) self.Refresh() def UpdateCount(self): self.SetItemCount(self.datasource.GetCount()) def Populate(self): self.UpdateCount() self.datasource.MakeImgList(self.il) self.SetImageList(self.il, IMAGE_LIST_SMALL) self.ShowColumns() def ShowColumns(self): for col, (text, visible) in enumerate(self.datasource.GetColumnHeaders()): if visible: self.columns.append(text) self.InsertColumn(col, text, width = -2) def Filter(self, filter): self.datasource.Filter(filter) self.UpdateCount() self.Refresh() def ShowAvailableColumns(self, evt): colMenu = Menu() self.id2item = {} for idx, (text, visible) in enumerate(self.datasource.columns): id = NewId() self.id2item[id] = (idx, visible, text) item = MenuItem(colMenu, id, text, kind = ITEM_CHECK) colMenu.AppendItem(item) EVT_MENU(colMenu, id, self.ColumnToggle) item.Check(visible) Frame(self, -1).PopupMenu(colMenu) colMenu.Destroy() def ColumnToggle(self, evt): toggled = self.id2item[evt.GetId()] if toggled[1]: idx = self.columns.index(toggled[2]) self.datasource.columns[toggled[0]] = (self.datasource.columns[toggled[0]][0], False) self.DeleteColumn(idx) self.columns.pop(idx) else: self.datasource.columns[toggled[0]] = (self.datasource.columns[toggled[0]][0], True) idx = self.datasource.GetColumnHeaders().index((toggled[2], True)) self.columns.insert(idx, toggled[2]) self.InsertColumn(idx, toggled[2], width = -2) self.datasource.SaveColumns() I've added functions that allow for Column Toggling which facilitate my description of the issue I'm encountering. On the 3rd instance of this class in my application the Column at Index 1 will not display String values. Integer values are displayed properly. If I add print statements to my OnGetItemText method the values show up in my console properly. This behavior is not present in the first two instances of this class, and my class does not contain any type checking code with respect to value display. It was suggested by someone on the wxPython users' group that I create a standalone sample that demonstrates this issue if I can. I'm working on that, but have not yet had time to create a sample that does not rely on database access. Any suggestions or advice would be most appreciated. I'm tearing my hair out on this one.

  • Flex/Flash 4 datagrid literally displays XML

    - by Setori
    Problem: Flex/Flash4 client (built with FlashBuilder4) displays the xml sent from the server exactly as is - the datagrid keeps the format of the xml. I need the datagrid to parse the input and place the data in the correct rows and columns of the datagrid. flow: click on a date in the tree and it makes a server request for batch information in xml form. Using a CallResponder I then update the datagrid's dataProvider.

  • Python form POST using urllib2 (also question on saving/using cookies)

    - by morpheous
    I am trying to write a function to post form data and save returned cookie info in a file so that the next time the page is visited, the cookie information is sent to the server (i.e. normal browser behavior). I wrote this relatively easily in C++ using curlib, but have spent almost an entire day trying to write this in Python, using urllib2 - and still no success. This is what I have so far: import urllib, urllib2 import logging # the path and filename to save your cookies in COOKIEFILE = 'cookies.lwp' cj = None ClientCookie = None cookielib = None logger = logging.getLogger(__name__) # Let's see if cookielib is available try: import cookielib except ImportError: logger.debug('importing cookielib failed. Trying ClientCookie') try: import ClientCookie except ImportError: logger.debug('ClientCookie isn\'t available either') urlopen = urllib2.urlopen Request = urllib2.Request else: logger.debug('imported ClientCookie succesfully') urlopen = ClientCookie.urlopen Request = ClientCookie.Request cj = ClientCookie.LWPCookieJar() else: logger.debug('Successfully imported cookielib') urlopen = urllib2.urlopen Request = urllib2.Request # This is a subclass of FileCookieJar # that has useful load and save methods cj = cookielib.LWPCookieJar() login_params = {'name': 'anon', 'password': 'pass' } def login(theurl, login_params): init_cookies(); data = urllib.urlencode(login_params) txheaders = {'User-agent' : 'Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)'} try: # create a request object req = Request(theurl, data, txheaders) # and open it to return a handle on the url handle = urlopen(req) except IOError, e: log.debug('Failed to open "%s".' % theurl) if hasattr(e, 'code'): log.debug('Failed with error code - %s.' % e.code) elif hasattr(e, 'reason'): log.debug("The error object has the following 'reason' attribute :"+e.reason) sys.exit() else: if cj is None: log.debug('We don\'t have a cookie library available - sorry.') else: print 'These are the cookies we have received so far :' for index, cookie in enumerate(cj): print index, ' : ', cookie # save the cookies again cj.save(COOKIEFILE) #return the data return handle.read() # FIXME: I need to fix this so that it takes into account any cookie data we may have stored def get_page(*args, **query): if len(args) != 1: raise ValueError( "post_page() takes exactly 1 argument (%d given)" % len(args) ) url = args[0] query = urllib.urlencode(list(query.iteritems())) if not url.endswith('/') and query: url += '/' if query: url += "?" + query resource = urllib.urlopen(url) logger.debug('GET url "%s" => "%s", code %d' % (url, resource.url, resource.code)) return resource.read() When I attempt to log in, I pass the correct username and pwd,. yet the login fails, and no cookie data is saved. My two questions are: can anyone see whats wrong with the login() function, and how may I fix it? how may I modify the get_page() function to make use of any cookie info I have saved ?

  • notification scheduling question

    - by sims
    Hi Stackers! I'm building an app that needs to send out notifications to users depending on user definable "notifications". So the notifications are not per event. They are arbitrary. A cron job should query the database and send out emails when it finds an event with matching criterion. The is a scheduling app. So naturally, one of the criterion is time. I think I've figured it out, but I'm sure there are better ideas out there as it seems to be a fairly common thing to do. I think I'll limit the users ability to "minutes before hand" to get notified as opposed to seconds or hours. So I have an eventA and notificationA. notificationA should be triggered if an event is due within 45 minutes. So eventA starts at 17:30. The user should be notified at 16:45. But the cron job might not run exactly at 00 seconds. So when the difference is not 45 minutes and 0 seconds it is, say, 45 minutes and 5 seconds. Notification time is past. Email doesn't get sent. User misses event. Shugar. We should also take into account that the cron job might take a long time to run. So maybe we should only trigger it every 5 minutes. So we need a bigger interval maybe. So then my guess would be to say that: if ((eventDueTime - now notificationTimeValue - interval) && (eventDueTime - now < notificationTimeValue + interval)) sendTheFrikinNotificationAlready(); It seems kind of risky if the there are thousands of notifications to send out. I guess I could make a thread for each notification and then a thread for each event that matches the criterion. That might help. Does that make sense? Any other ideas? Thanks!

  • Prototype JS swallows errors in dom:loaded, and ajax callbacks?

    - by WishCow
    I can't figure out why prototype suppressess the error messages in the dom:loaded event, and in AJAX handlers. Given the following piece of HTML: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Conforming XHTML 1.1 Template</title> <script type="text/javascript" src="prototype.js"></script> <script type="text/javascript"> document.observe('dom:loaded', function() { console.log('domready'); console.log(idontexist); }); </script> </head> <body> </body> </html> The domready event fires, I see the log in the console, but there is no indication of any errors whatsoever. If you move the console.log(idontexist); line out of the handler, you get the idontexist is not defined error in the console. I find it a little weird, that in other event handlers, like 'click', you get the error message, it seems that it's only the dom:loaded that has this problem. The same goes for AJAX handlers: new Ajax.Request('/', { method: 'get', onComplete: function(r) { console.log('xhr complete'); alert(youwontseeme); } }); You won't see any errors. This is with prototype.js 1.6.1, and I can't find any indication of this behavior in the docs, nor a way to enable error reporting in these handlers. I have tried stepping through the code with FireBug's debugger, and it seems to jump to a function on line 53 named K, when it encounters the missing variable in the dom:loaded handler: K: function(x) { return x } But how? Why? When? I can't see any try/catch block there, how does the program flow end up there? I know that I can make the errors visible by packing my dom:ready handler(s) in try/catch blocks, but that's not a very comfortable option. Same goes for registering a global onException handler for the AJAX calls. Why does it even suppress the errors? Did someone encounter this before?

  • Flex - Problem with auto resizing datagrid

    - by Marty Pitt
    Hi All I'm trying to create a datagrid which will resize vertically to ensure all the renderers are displayed in full. Additionally, Renderers are of variable height Renderers can resize themselves Generally speaking, the flow of events is as follows : One of the item renderers resizes itself (normally in response to a user click etc) It dispatches a bubbling event which the parent datagrid picks up The DataGrid attempts to resize to ensure that all renderers remain visible in full. I'm currently using this code within the datagrid to calculate the height: height = measureHeightOfItems(0, dataProvider.length ) + headerHeight; This appears to get an incorrect height. I've tried a number of variations including callLater ( to ensure the resize has completed so measure can work correctly), and overriding meausre() and calling invalidateSize() / validateSize(), but neither works. Below are 3 classes which will illustrate the problem. Clicking the button in the item renderers resizes the renderer. The grid should also expand so that all of the 3 renderers are shown in their entirety. Any suggestions would be greatly appreciated.

  • Segmentation fault in std function std::_Rb_tree_rebalance_for_erase ()

    - by Sarah
    I'm somewhat new to programming and am unsure how to deal with a segmentation fault that appears to be coming from a std function. I hope I'm doing something stupid (i.e., misusing a container), because I have no idea how to fix it. The precise error is Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: KERN_INVALID_ADDRESS at address: 0x000000000000000c 0x00007fff8062b144 in std::_Rb_tree_rebalance_for_erase () (gdb) backtrace #0 0x00007fff8062b144 in std::_Rb_tree_rebalance_for_erase () #1 0x000000010000e593 in Simulation::runEpidSim (this=0x7fff5fbfcb20) at stl_tree.h:1263 #2 0x0000000100016078 in main () at main.cpp:43 The function that exits successfully just before the segmentation fault updates the contents of two containers. One is a boost::unordered_multimap called carriage; it contains one or more struct Infection objects that contain two doubles. The other container is of type std::multiset< Event, std::less< Event EventPQ called ce. It is full of Event structs. void Host::recover( int s, double recoverTime, EventPQ & ce ) { // Clearing all serotypes in carriage // and their associated recovery events in ce // and then updating susceptibility to each serotype double oldRecTime; int z; for ( InfectionMap::iterator itr = carriage.begin(); itr != carriage.end(); itr++ ) { z = itr->first; oldRecTime = (itr->second).recT; EventPQ::iterator epqItr = ce.find( Event(oldRecTime) ); assert( epqItr != ce.end() ); ce.erase( epqItr ); immune[ z ]++; } carriage.clear(); calcSusc(); // a function that edits an array cout << "Done with sync_recovery event." << endl; } The last cout << line appears immediately before the seg fault. I hope this is enough (but not too much) information. My idea so far is that the rebalancing is being attempting on ce after this function, but I am unsure why it would be failing. (It's unfortunately very hard for me to test this code by removing particular lines, since they would create logical inconsistencies and further problems, but if experienced programmers still think this is the way to go, I'll try.)

  • QT vs. Net - REAL comparisons for R.A.D. projects

    - by Pirate for Profit
    Man in all these Qt vs. .NET discussions 90% these people argue about the dumbest crap. Trying to get a real comparison chart here, because I know a little about both frameworks but I don't know everything. I believe Qt and .NET both have strengths and weaknesses. This is to make a comparison that highlights these so people can make more informed decisions before embarking on a project, in the spirit of R.A.D. Event Handling In Qt the event handling system is very simple. You just emit signals when something cool happens and then catch them in slots. ie. // run some calculations, then emit valueChanged(30, false, 20.2); and then catching it, any object can make a slot to recieve that message easily void MyObj::valueChanged(int percent, bool ok, float timeRemaining). It's easy to "block" an event or "disconnect" when needed, and works seamlessly across threads... once you get the hang of it, it just seems a lot more natural and intuitive than the way the .NET event handling is set up (you know, void valueChanged(object sender, CustomEventArgs e). And I'm not just talking about syntax, because in the end the .NET anonymous delegates are the bomb. I'm also talking about in more than just reflection (because, yes, .NET obviously has much stronger reflection capabilities). I'm talking about in the way the system feels to a human being. Qt wins hands down for the simplest yet still flexible event handling system ever i m o. Plugins and such I do love some of the ease of C# compared to C++, as well as .NET's assembly architecture, even though it leads to a bunch of .dll's (there's ways to combine everything into a single exe though). That is a big bonus for modular projects, which are a PITA to import stuff in C++ as far as RAD is concerned. Database Ease of Doing Crap Also what about datasets and database manipulations. I think .net wins here but I'm not sure. Threading/Conccurency How do you guys think of the threading? In .NET, all I've ever done is make like a list of master worker threads with locks. I like QConcurrentFramework, you don't worry about locks or anything, and with the ease of the signal slot system across threads it's nice to get notified about the progress of things. QConcurrent is the simplest threading mechanism I've ever played with. Memory Usage Also what do you think of the overall memory usage comparison. Is the .NET garbage collector pretty on the ball and quick compared to the instantaneous nature of native memory management? Or does it just let programs leak up a storm and lag the computer then clean it up when it's about to really lag? Doesn't the just-in-time compiler make native code that is pretty good, like and that only happens the first time the program is run? However, I am a n00b who doesn't know what I'm talking about, please school me on the subject.

  • enclosing double quotes in array

    - by Jared
    Hi all I might be looking at this the wrong way, but I have a form that does its thing (sends emails etc etc) but I also put in some code to make a simple flatfile csv log with some of the user entered details. If a user accidentally puts in for instance 'himynameis","bob' this would either break the csv row (because the quotes weren't encapsulated) or if I use htmlspecialchars() and stripslashes() on the data, I end up with a ugly data value of 'himynameis&quot;,&quot;bob'. My question is, how can I handle the incoming data to cater for '"' being put in the form without breaking my csv file? this is my code for creating the csv log file. @$name = htmlspecialchars(trim($_POST['name'])); @$emailCheck = htmlspecialchars(trim($_POST['email'])); @$title = htmlspecialchars(trim($_POST['title'])); @$phone = htmlspecialchars(trim($_POST['phone'])); function logFile($logText) { $path = 'D:\logs'; $filename = '\Log-' . date('Ym', time()) . '.csv'; $file = $path . $filename; if(!file_exists($file)) { $logHeader = array('Date', 'IP_Address', 'Title', 'Name', 'Customer_Email', 'Customer_Phone', 'file'); $fp = fopen($file, 'a'); fputcsv($fp, $line); } $fp = fopen($file, 'a'); foreach ($logText as $record) { fputcsv($fp, $record); } } //Log submission to file $date = date("Y/m/d H:i:s"); $clientIp = getIpAddress(); //get clients IP address $nameLog = stripslashes($name); $titleLog = stripslashes($title); if($_FILES['uploadedfile']['error'] == 4) $filename = "No file attached."; //check if file uploaded and return $logText = array(array("$date", "$clientIp", "$titleLog", "$nameLog", "$emailCheck", "$phone", "$filename")); logFile($logText); //write form details to log Here is a sample of the incoming array data: Array ( [0] => Array ( [0] => 2010/05/17 10:22:27 [1] => xxx.xxx.xxx.xxx [2] => title [3] => """"himynameis","bob" [4] => [email protected] [5] => 346346 [6] => No file attached. ) ) TIA Jared

  • Write STDOUT & STDERR to a logfile, also write STDERR to screen

    - by Stefan Lasiewski
    I would like to run several commands, and capture all output to a logfile. I also want to print any errors to the screen (or optionally mail the output to someone). Here's an example. The following command will run three commands, and will write all output (STDOUT and STDERR) into a single logfile. { command1 && command2 && command3 ; } > logfile.log 2>&1 Here is what I want to do with the output of these commands: STDERR and STDOUT for all commands goes to a logfile, in case I need it later--- I usually won't look in here unless there are problems. Print STDERR to the screen (or optionally, pipe to /bin/mail), so that any error stands out and doesn't get ignored. It would be nice if the return codes were still usable, so that I could do some error handling. Maybe I want to send email if there was an error, like this: { command1 && command2 && command3 ; } logfile.log 2&1 || mailx -s "There was an error" [email protected] The problem I run into is that STDERR loses context during I/O redirection. A '2&1' will convert STDERR into STDOUT, and therefore I cannot view errors if I do 2 error.log Here are a couple juicier examples. Let's pretend that I am running some familiar build commands, but I don't want the entire build to stop just because of one error so I use the '--keep-going' flag. { ./configure && make --keep-going && make install ; } > build.log 2>&1 Or, here's a simple (And perhaps sloppy) build and deploy script, which will keep going in the event of an error. { ./configure && make --keep-going && make install && rsync -av --keep-going /foo devhost:/foo} > build-and-deploy.log 2>&1 I think what I want involves some sort of Bash I/O Redirection, but I can't figure this out.

  • Android: handle unexpected internet disconnect while downloading data

    - by M.A. Cape
    Hi, I have here a function that downloads data from a remote server to file. I am still not confident with my code.

  • Zend database query result converts column values to null

    - by David Zapata
    Hi again. I am using the next instructions to get some registers from my Database. Create the needed models (from the params module): $obj_paramtype_model = new Params_Model_DbTable_Paramtype(); $obj_param_model = new Params_Model_DbTable_Param(); Getting the available locales from the database // This returns a Zend_Db_Table_Row_Abstract class object $obj_paramtype = $obj_paramtype_model->getParamtypeByValue('available_locales'); // This is a query used to add conditions to the next sentence. This is executed from the Params_Model_DbTable_Param instance class, that depends from Params_Model_DbTable_Paramtype class (reference map and dependentTables arrays are fine in both classes) $obj_select = $this->select()->where('deleted_at IS NULL')->order('name'); // Execute the next query, applying the select restrictions. This returns a Zend_Db_Table_Rowset_Abstract class object. This means "Find Params by Paramtype" $obj_params_rowset = $obj_paramtype->findDependentRowset('Params_Model_DbTable_Param', 'Paramtype', $obj_paramtype); // Here the firebug log displays the queries.... Zend_Registry::get('log')->debug($obj_params_rowset); I have a profiler for all my DB executions from Zend. At this point the log and profiler objects (that includes Firebug writers), shows the executed SQL Queries, and the last line displays the resulting Zend_Db_Table_Rowset_Abstract class object. If I execute the SQL Queries in some MySQL Client, the results are as expected. But the Zend Firebug log writer displays as NULL the column values with latin characters (ñ). In other words, the external SQL client shows es_CO | Español de Colombia and en_US | English of United States but the Query results from Zend displays (and returns) es_CO | null and en_US | English of United States. I've deleted the ñ character from Español de Colombia and the query results are just fine in my Zend Log Firebug screen, and in the final Zend Form element. The MySQL database, tables and columns are in UTF-8 - utf8_unicode_ci collation. All my zend framework pages are in UTF-8 charset. I'm using XAMPP 1.7.1 (PHP 5.2.9, Apache at port 90 and MySQL 5.1.33-community) running on Windows 7 Ultimate; Zend Framework 1.10.1. I'm sorry if there is so much information, but I don't really know why could that happen, so I tryed to provide as much related information as I could to help to find some answer.

  • Problem with type coercion and string concatenation in JavaScript in Greasemonkey script on Firefox

    - by Yi Jiang
    I'm creating a GreaseMonkey script to improve the user interface of the 10k tools Stack Overflow uses. I have encountered an unreproducible and frankly bizarre problem that has confounded me and the others in the JavaScript room on SO Chat. We have yet to find the cause after several lengthy debugging sessions. The problematic script can be found here. Source - Install The problem occurs at line 85, the line after the 'vodoo' comment: return (t + ' (' + +(+f.offensive + +f.spam) + ')'); It might look a little weird, but the + in front of the two variables and the inner bracket is for type coercion, the inner middle + is for addition, and the other ones are for concatenation. Nothing special, but observant reader might note that type coercion on the inner bracket is unnecessary, since both are already type coerced to numbers, and type coercing result is useless when they get concatenated into a string anyway. Not so! Removing the + breaks the script, causing f.offensive and f.spam to be concatenated instead of added together. Adding further console.log only makes things more confusing: console.log(f.offensive + f.spam); // 50 console.log('' + (+f.offensive + +f.spam)); // 5, but returning this yields 50 somehow console.log('' + (+f.offensive + +f.spam) + ''); // 50 Source: http://chat.stackoverflow.com/transcript/message/203261#203261 The problem is that this is unreproducible - running scripts like console.log('a' + (+'3' + +'1') + 'b'); in the Firebug console yields the correct result, as does (function(){ return 'a' + (+'3' + +'1') + 'b'; })(); Even pulling out large chunks of the code and running them in the console does not reproduce this bug: $('.post-menu a[id^=flag-post-]').each(function(){ var f = {offensive: '4', spam: '1'}; if(f){ $(this).text(function(i, t){ // Vodoo - please do not remove the '+' in front of the inner bracket return (t + ' (' + +(+f.offensive + +f.spam) + ')'); }); } }); Tim Stone in the chatroom has reproduction instruction for those who are below 10k. This bug only appears in Firefox - Chrome does not appear to exhibit this problem, leading me to believe that this may be a problem with either Firefox's JavaScript engine, or the Greasemonkey add-on. Am I right? I can be found in the JavaScript room if you want more detail and/or want to discuss this.

  • ASP.NET RadioButtonList help. If I set a selectedItem, that item doesn't react to SelectedIndexChang

    - by Hcabnettek
    Hi Guys, I have a RadioButtonList on my web form. I have tried two different means to set the selected item. I have tried in the markup, and in code, like the Page_Load event. It sets and displays correctly. My problem is that the selected radio button no longer responds to the SelectedIndexChanged event. The other items works as expected and if I remove the code that sets the selectedItem, then the radio button works as expected. Is there any way I can set a radio button through code, and it still behaves as I would expect. I am guessing, if u force a button to be selected, then it doesn't change. Does anyone know how to rememdey this so I can default select it, but still have it behave the way I want? <asp:RadioButtonList ID="rblPaymentType" runat="server" AutoPostBack="True" RepeatDirection="Horizontal" RepeatLayout="Flow"> <asp:ListItem Value="benefit" Text="Benefit" Selected="True"/> <asp:ListItem Value="expense" Text="Expense" /> </asp:RadioButtonList> This lives inside an ascx which I have an event for public delegate void SwitchBenefitTypeHandler(object sender, EventArgs e); public event SwitchBenefitTypeHandler SwitchedBenefit; protected void Page_Load(object sender, EventArgs e) { WireEvents(); } private void WireEvents() { rblPaymentType.SelectedIndexChanged += (sender, args) => SwitchedBenefit(sender, args); } Then on the aspx, I wire a handler function to that event. if (header is PaymentHeader) (header as PaymentHeader).SwitchedBenefit += (paymentForm as PaymentBaseControl).Update; Finally the handler function public override void Update(object sender, EventArgs e) { if (sender is RadioButtonList) { IsExpense = (sender as RadioButtonList).SelectedValue == "expense"; UpdateCalcFlag(); UpdateDropDownDataSources(); UpdatePaymentTypeDropDown(); ResetBenefitLabels(); FormatAmountTextBox(); } } I hope that's enough code. Everything works great when I don't set the SelectedItem in the RadioButtonList but I need it set. Here's a link to someone with the same problem. It is ASP.NET AJAX related.

  • How can I refactor out needing so many for-loops in rails?

    - by Angela
    I need help refactoring this multi-loop thing. Here is what I have: Campaign has_many Contacts Campaign also has many templates for EVent (Email, Call, and Letter). I need a list of all the Emails, Calls and Letters that are "overdue" for every Contact that belongs to a Campaign. Overdue is determined by a from_today method which looks at the date the Contact was entered in the system and the number of days that needs to pass for any given Event. from_today() outputs the number of days from today that the Event should be done for a given Contact. Here is what I've done, it works for all Emails in a Campaign across all contacts. I was going to try to create another each do loop to change the class names. Wasn't sure where to begin: named_scope, push some things into a method, etcetera, or -- minimum to be able to dynamically change the class names so at least it loops three timees across the different events rather than repeating the code three times: <% @campaigns.each do |campaign| %> <h2><%= link_to campaign.name, campaign %></h2> <% @events.each do |event| %> <%= event %> <% for email in campaign.emails %> <h4><%= link_to email.title, email %> <%= email.days %> days</h4> <% for contact in campaign.contacts.find(:all, :order => "date_entered ASC" ) %> <% if (from_today(contact, email.days) < 0) %> <% if show_status(contact, email) == 'no status'%> <p> <%= full_name(contact) %> is <%= from_today(contact,email.days).abs%> days overdue: <%= do_event(contact, email) %> </p> <% end %> <% end %> <% end %> <% end %> <% end %> <% end %>
