  • How to repaint another Qt class

    - by RR
    Hi all, I'm a new bit in Qt... I have a Qt GUI application (written by me), let's call it QtAPP.exe When QtAPP.exe running, I will use a QThread and QProcess to execute some external file, such as player.exe (written in native C). Here's my question: In QtAPP.exe, there are 2 classes, 1. QMainWindow - Core of QtAPP.exe 2. QThread - A thread class to execute external things For now, if I got a finished() signal in that QThread, how do I to force the QMainWindow to repaint itself ? Hope somebody can show me some tips, maybe sample code :) Any suggestion are welcome~

    I am trying to create a zip folder of my downloaded images. Here is my code.

  • Visual Studio 2008, MSBuild: "replacement" projects

    - by liori
    Hello, My solution has a library project which needs a special environment to be built (lots of external libraries and tools)... but it is not vital to our application. We'd like to avoid installing these tools when not necessary (most of our developers work on other parts of code). We have created another project which has the same API, but has an empty implementation and is compilable without those external tools. I'd like to be able to easily switch between those projects and still get all the references in other projects correct. I don't know VS/MSBuild very well, but willing to learn whatever is necessary. Is it possible? I am looking for ideas... We're using Subversion, and solutions involving some hacks inside VCS are also welcome.

  • Database Programming in C#, returning output from Stored Proc

    - by jpavlov
    I am working at gaining an understanding at how to interface stored procedures with applications. My example is simple, but it doesn't display my columns and rows in the command prompt, instead it display System.Data.SqlClient.SqlDataReader. How do I display the rows from my stored procudure? ----Stored Proc-- ALTER PROCEDURE dbo.SelectID AS SELECT * FROM tb_User; ----- Below is the code: using System; using System.Data.SqlClient; using System.IO; namespace ExecuteStoredProc { class Program { static void Main(string[] args) { SqlConnection cnnUserMan; SqlCommand cmmUser; //SqlDataReader drdUser; //Instantiate and open the connection cnnUserMan = new SqlConnection("Data Source=.\\SQLEXPRESS;AttachDbFilename=c:\\Program Files\\Microsoft SQL Server\\MSSQL10.SQLEXPRESS\\MSSQL\\DATA\\UserDB.mdf; Integrated Security=True;Connect Timeout=30;User Instance=True"); cnnUserMan.Open(); //Instantiate and initialize command cmmUser = new SqlCommand("SelectID", cnnUserMan); cmmUser.CommandType = System.Data.CommandType.StoredProcedure; //drdUser = cmmUser.ExecuteReader(); Console.WriteLine(cmmUser.ExecuteReader()); Console.ReadLine(); } } } Thanks.

  • PHP - Drilling down Data and Looping with Loops

    - by stogdilla
    I'm currently having difficulty finding a way of making my loops work. I have a table of data with 15 minute values. I need the data to pull up in a few different increments $filters=Array('Yrs','Qtr','Day','60','30','15'); I think I have a way of finding out what I need to be able to drill down to but the issue I'm having is after the first loop to cycle through all the Outter most values (ex: the user says they want to display by Hours, each hour should be able to have a "+" that will then add a new div to display the half hour data, then each half hour data have a "+" to display the 15 minute data upon request. Now I can just program the number of outputs for each value (6 different outputs) just in-case... but isn't there a way I can make it do the drill down for each one in a loop? so I only have to code one output once and have it just check if there are any more intervals after it and check for those? I'm sure I'm just overlooking some very simple way of doing this but my brain isn't being clever today. Sorry in advance if this is a simple solution. I guess the best way I could think of it as a reply on a form. How you would check to see if it's a reply of a reply, and then if that reply has any replys...etc for output. Can anyone help or at least point me in the right direction? Or am I stuck coding each possible check? Thanks in advance!

  • JQuery overlay - issues with opening twitter "Allow Access" box

    - by Gublooo
    Hey guys I'm using Jquery flowplayer tools overlay to open external links. External links are working fine with this piece of code shown in the link: http://www.demiseonline.com/misc/Iframeoverlay.html Now using this overlay - I wanted to open the twitter dialog which asks users to Allow access to their account. So in the code below, I replaced http://www.google.com with https://twitter.com/oauth/authenticate?oauth_token=VPVRIsnRz9IX4CAab7brert3jHiEs <div class="apple_overlay black" id="Overlay1" <iframe src ="http://www.google.com" width="100%" height="595px" frameborder="0" </iframe </div When I replace the code, as soon as I load the page, even before I click on the link to open the overlay - the page gets redirected to the twitter URL. Any idea why that happens for this URL. Thanks

  • Using the StackTrace Class in a production environment to get calling method info

    - by andy
    hey guys We have a "log" class which uses Relection.MethodBase to send current class info to the log. The reflection.MethodBase stuff happens in the class itself. However, I'd like to move that stuff to a single external "log" singleton type class. In this scenario the external log class needs to get the CALLING info, not the current method info. I'm using stacktrace to do this, which isn't in the Reflection namespace. Can I guarantee that "that" specific information (calling method) will be there in a production environment? var stackTrace = new StackTrace(); return LogManager.GetLogger(stackTrace.GetFrame(1).GetMethod().DeclaringType); cheers!

  • Weird margin in a list

    - by kevin
    I'm trying to style a menu, but I keep running into this weird margin that's appearing in both FF4 and IE. This is the only affecting css: #header ul { display: inline; } #header ul li { list-style-type: none; background: #000; display: inline; margin: 0; padding: 0; } #header ul li a { color: #fff; text-decoration: none; display: inline-block; width: 100px; text-align: center; } And this is the HTML: <div id="header"> <ul id="toplinks"> <li><a href="#">Hello</a></li> <li><a href="#">Herp</a></li> <li><a href="#">Derp</a></li> </ul> </div> As you can see, there's a margin appearing on both sides, and I'd like it so it would have no margin (or maybe 1px would be okay)...

  • How do I connect two apps

    - by sevaxx
    I am considering building an app in C++ that will be parsing text from the web and create some statistical results. These results I want to be fed in an external app in real time. The external app (to whose code I have no access, but can ask for a - paid - custom made addition) will then need some code to read and use these results. I am wondering what would be the best way to interconnect the two apps, in terms of speed and ease of implementation. I am considering : disk I/O (slow) a Windows service a DLL a web service a web page Perhaps I am missing a better solution ? Thank you.

  • What's a good way to throw and handle events in PHP?

    - by techexpert
    Hi everyone, I am just trying to get a general idea about the event prcessing mechanism in PHP5 in as neat way as possible. First of all I understand that a PHP application is not exactly a persistent type, so the events may not make a lot of sense, but from the OO perspective it might be a very elegant way to "communicate" between the objects. So I am thinking that it would make sense to separate the events on the external events, such as $_POST & $_GET and the internal ones, i.e. function callbacks. As far as the external ones, is it a good idea to process the $_GETs and $_POSTs directly, or is it better to wrap them into an event of some sort? Also, in order to process the internal events, do you have to pass the reference to the event handler/dispatcher to each class so they know how to throw them? I was thinking to use the PEAR EventDispatcher to do the work, but I am open to other suggestions. Thank you!

  • Knowing which annotation is selected and accessing properties of it.

    - by kevin Mendoza
    So far my program can display a database of custom annotation views. Eventually I want my program to be able to display extra information after a button on the annotation bubble is clicked. Each element in the database has a unique entry Number, so I thought it would be a good idea to add this entry number as a property of the custom annotation. The problem I am having is that after the button is clicked and the program switches to a new view I am unable to retrieve the entry number of the annotation I selected. Below is the code that assigns the entry Number property to the annotation: for (id mine in mines) { workingCoordinate.latitude = [[mine latitudeInitial] doubleValue]; workingCoordinate.longitude = [[mine longitudeInitial] doubleValue]; iProspectAnnotation *tempMine = [[iProspectAnnotation alloc] initWithCoordinate:workingCoordinate]; [tempMine setTitle:[mine mineName]]; [tempMine setAnnotationEntryNumber:[mine entryNumber]]; } [mines dealloc]; When the button on an annotation is selected, this is the code that initializes the new view: - (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control { mineInformationController *controller = [[mineInformationController alloc] initWithNibName:@"mineInformationController" bundle:nil]; controller.modalTransitionStyle = UIModalTransitionStyleCrossDissolve; [self presentModalViewController:controller animated:YES]; [controller release]; } and lastly is my attempt at retrieving the entryNumber property from the new view so that I can compare it to the mines database and retrieve more information on the array element. iProspectFresno_LiteAppDelegate *appDelegate = (iProspectFresno_LiteAppDelegate *)[[UIApplication sharedApplication] delegate]; NSMutableArray* mines = [[NSMutableArray alloc] initWithArray:(NSMutableArray *)appDelegate.mines]; for(id mine in mines) { if ([[mine entryNumber] isEqualToNumber: /*the entry Number of the selected annotation*/]) { /* display the information in the mine object */ } } So how do I access this entry number property in this new view controller?

  • Visual-C++ Linker Error

    - by LordByron
    I have a class called MODEL in which public static int theMaxFrames resides. The class is defined in its own header file. theMaxFrames is accessed by a class within the MODEL class and by one function, void set_up(), which is also in the MODEL class. The Render.cpp source file contains a function which calls a function in the Direct3D.cpp source file which in turn calls the set_up() function through a MODEL object. This is the only connection between these two source files and theMaxFrames. When I try to compile my code I get the following error messages: 1Direct3D.obj : error LNK2001: unresolved external symbol "public: static int MODEL::theMaxFrames" (?theMaxFrames@MODEL@@2HA) 1Render.obj : error LNK2001: unresolved external symbol "public: static int MODEL::theMaxFrames" (?theMaxFrames@MODEL@@2HA) 1C:\Users\Byron\Documents\Visual Studio 2008\Projects\xFileViewer\Debug\xFileViewer.exe : fatal error LNK1120: 1 unresolved externals

  • Do I want an embedded web-server, or what?

    - by mawg
    So, someone want me to hack some code for him. He has a 42" TFT display on which he will display some application/business related data. However, 75% of the screen real estate is unused, so he wants to fill it with "TV/adverts/flash/you know, that kind of thing... web based....". Any advice? Do I want an embedded web-server? If so, which? (he wants free & open source, or as cheap as possible) Do I display it in a browser? (duh! probably, dude) But I don't want/need a menu, address bar, toolbar, etc - it should be full screen (does that mean "kiosk mode"?). Sorry, folks, the requirements are not clear, but I hope that you can guess what he probably means (he is not very techie). How should I proceed with this? Thanks.

  • How do I include 3rd party libraries in my code...

    - by Krakkos
    I understand the process of using a 3rd party library to access functions outside of my code base, but how do i actually set up Visual Studio 2005 to include them in the project. I have a 3rd party library with some headers, some cpp's, and some .lib files. In the projects properties I add the top level external library directory as an include directory, I add the additional library directory at the same level put this is project properties too. In the .cpp file where I use the functions, do I put the #include in its header file? In the top level projects header file? in the cpp? I've tried all that, but I get "unresolved external symbol"... grrrrrrrrrrrrr

  • Error 2025: The supplied DisplayObject must be a child of the caller

    - by Mocca
    Hi, sorry, new to actionscript 3. I have a display() function for an object rotator(image based like a QT object movie). It first saves the current image in a helper variable and then allocates a new image, from the library, beneath the old one. To get a nice crossfade effect, the old image's alpha is looped down via enter_frame and then removed. Which is where there seems to be an issue with the display list, maybe recognizing oldImg's value as being already added? (it's not a first pass error) Btw, do i have to remove the old image or can i leave it, for when it's being called up via the mouse position again? (the image number can get fairly large) Does anyone have further insight? Thanks! function display(num:Number):void //num: image number { ... oldImg = newImg; ClassReference = getDefinitionByName("Class"+num) as Class; imgBD = new ClassReference(0,0); newImg = new Bitmap(imgBD); images.addChild(newImg); newImg.x=0; newImg.y=0; } function onEnter(evt:Event):void { if (oldImg) { if (oldImg.alpha > 0) oldImg.alpha -= 0.15; **else images.removeChild(oldImg);** } ... }

  • How do I escape a string for a shell command in nodejs (V8 Javascript engine)?

    - by Maciek
    In nodejs, the only way to execute external commands is via sys.exec(cmd). I'd like to call an external command and give it data via stdin. In nodejs there does yet not appear to be a way to open a command and then push data to it (only to exec and receive its standard+error outputs), so it appears the only way I've got to do this right now is via a single string command such as: var dangerStr = "bad stuff here"; sys.exec("echo '" + dangerStr + "' | somecommand"); Most answers to questions like this have focused on either regex which doesn't work for me in nodejs (which uses Google's V8 Javascript engine) or native features from other languages like Python. I'd like to escape dangerStr so that it's safe to compose an exec string like the one above. If it helps, dangerStr will contain JSON data.

  • are mobile can be used as a devices to develop application

    - by Richa Media and services
    I say that we can work @ mobile using a technique and work with any IDE and use any OS without problem like work on visual studio and use Window 7 How it possible ? 1. We use Mobile like a CPU and Use a monitor to watch code. We use samsung's techniques to display on monitor. it's give signal to monitor wirelessly to display code on monitor 2 We use Wireless keyboard and Mouse (if user like USB then he also use USB keyboard and mouse) 3. We use a component inside of mobile to control all devices like internet , wi-fi bluethoth. by component user easily setup , control and use feature. 4 don't be confused. i am sure to say that we not use mobile to watch code on mobile screen and Mobile 's keyboard because it's too smaller to work so we use Monitor (LCD) to display code and a keyboard to work comfortably and freely. 5. what are you think if you see a developer who work using this way 6. it is not impossible. give me some feedback and suggestion about your thinking on this technologies.

  • algorithm to combine data for linear fit?

    - by BoldlyBold
    I'm not sure if this is the best place to ask this, but you guys have been helpful with plenty of my CS homework in the past so I figure I'll give it a shot. I'm looking for an algorithm to blindly combine several dependent variables into an index that produces the best linear fit with an external variable. Basically, it would combine the dependent variables using different mathematical operators, include or not include each one, etc. until an index is developed that best correlates with my external variable. Has anyone seen/heard of something like this before? Even if you could point me in the right direction or to the right place to ask, I would appreciate it. Thanks.

  • Can I attach a .NET TraceListener to an externally running process?

    - by BBlake
    I am developing an application scheduling program that will run other applications using System.Diagnostics.Process. The external applications are of various types (some .NET and some not). For those external apps that have trace logging enabled, is there a way that I can attach the tracelistener of the parent/calling application to listen to and record all the trace output from the child/called application to the parent application's trace output? This is not primarily for debugging purposes. This is more to track trace output from all the various scheduled applications by collecting it into one place as much as possible. The scheduler app is still in the early design stages, but will be .NET, and I'm trying to clear up potential design issues before I get into it too far.

  • Glassfish complaining about JSF component IDs

    - by Brian
    Hello All I am very new to JSF (v2.0) and I am attempting to learn it at places like netbeans.org and coreservlets.com. I am working on a very simple "add/subtract/multiply/divide" Java webapp and I have run into a problem. When I first started out, the application was enter two numbers and hit a '+' key and they would be automatically added together. Now that I have added more complexity I am having trouble getting the operation to the managed bean. This is what I had when it was just "add": <h:inputText styleClass="display" id="number01" size="4" maxlength="3" value="#{Calculator.number01}" /> <h:inputText styleClass="display" id="number02" size="4" maxlength="3" value="#{Calculator.number02}" /> <h:commandButton id="add" action="answer" value="+" /> For the "answer" page, I display the answer like this: <h:outputText value="#{Calculator.answer}" /> I had the proper getters and setters in the Calculator.java managed bean and the operation worked perfectly. Now I have added the other three operations and I am having trouble visualizing how to get the operation parameter to the bean so that I can switch around it. I tried this: <h:commandButton id="operation" action="answer" value="+" /> <h:commandButton id="operation" action="answer" value="-" /> <h:commandButton id="operation" action="answer" value="*" /> <h:commandButton id="operation" action="answer" value="/" /> However, Glassfish complained that I have already used "operation" once and I am trying to use it four times here. Any adivce/tips on how to get multiple operations to the managed bean so that it can preform the desired operation? Thank you for taking the time to read.

  • How to deploy and secure an ASP.NET web app to be available to internal and outside users?

    - by Swoop
    My company has several web applications written in ASP.NET. We need to make these applications available to Intranet users as well as authenticated external users. Most of the features are the same for the two groups, though there are some extra features available to the Internal users. The two different sets of users would use a slightly different security setup... our internal people will be authenticated using LDAP against Exchange, whereas the external users will have accounts in SQL Server. What is the best approach for deploying our web apps? Should we deploy 2 copies to different servers, one configured for an Intranet and one for outside users? Or is there a better way to share the code between the 2 servers, yet have the flexibility to use different web.config settings for security??

  • Which network protocol to use for lightweight notification of remote apps (Delphi 2005)

    - by Chris Thornton
    I have this situation.... Client-initiated SOAP 1.1 communication between one server and let's say, tens of thousands of clients. Clients are external, coming in through our firewall, authenticated by certificate, https, etc.. They can be anywhere, and usually have their own firewalls, NAT routers, etc... They're truely external, not just remote corporate offices. They could be in a corporate/campus network, DSL/Cable, even Dialup. Currently, clients push new data to the server and pull new data from the server on 15-minute polling loop. The server currently does not push data - the client hits the "messagecount" method, to see if there is new data to pull. If 0, it sleeps for another 15 min and checks again. We're trying to get that down to 7 seconds. If this were an internal app, with one or just a few dozen clients, we'd write a cilent "listener" soap service, and would push data to it. But since they're external, sit behind their own firewalls, and sometimes private networks behind NAT routers, this is not practical. So we're left with polling on a much quicker loop. 10K clients, each checking their messagecount every 10 seconds, is going to be 1000/sec messages that will mostly just waste bandwidth, server, firewall, and authenticator resources. So I'm trying to design something better than what would amount to a self-inflicted DoS attack. I don't think it's practical to have the server send soap messages to the client (push) as this would require too much configuration at the client end. But I think there are alternatives that I don't know about. Such as: 1) Is there a way for the client to make a request for GetMessageCount() via Soap 1.1, and get the response, and then perhaps, "stay on the line" for perhaps 5-10 minutes to get additional responses in case new data arrives? i.e the server says "0", then a minute later in response to some SQL trigger (the server is C# on Sql Server, btw), knows that this client is still "on the line" and sends the updated message count of "5"? 2) Is there some other protocol that we could use to "ping" the client, using information gathered from their last GetMessageCount() request? 3) I don't even know. I guess I'm looking for some magic protocol where the client can send a GetMessageCount() request, which would include info for "oh by the way, in case the answer changes in the next hour, ping me at this address...". Also, I'm assuming that any of these "keep the line open" schemes would seriously impact the server sizing, as it would need to keep many thousands of connections open, simultaneously. That would likely impact the firewalls too, I think. Is there anything out there like that? Or am I pretty much stuck with polling? TIA, Chris
