  • the problem only happens when i try create a release...

    - by ace
    I'm sorry if im not presenting this right, but i trully cannot understand what the problem is. i have a project to hand in, a code of 600 lines defined within a main, .cpp, and header file. if i compile the project with just a debugger and no release, it's fine. when i create it with the release, the following error occurs, for every function!!! 1st error: |36|multiple definition of `countLines(int&, std::vector const&)'| 2nd error: |36|first defined here| if someone will allow me and i can send them the entire code, that would be awesome - i have to have this done within 3 hours.

  • Parameterise Service start option in WiX installer

    - by Jamiec
    I have a ServiceInstall component in a WiX installer where I have a requirement to either start auto or demand depending on parameters passed into the MSI. So the Xml element in question is <ServiceInstall Vital="yes" Name="My Windows Service" Type="ownProcess" Account="[SERVICEUSERDOMAIN]\[SERVICEUSERNAME]" DisplayName="My Service" Password="[SERVICEUSERPASSWORD]" Start="demand" Interactive="no" Description="Something interesting here" Id="Service" ErrorControl="ignore"></ServiceInstall> WiX will not allow using a PArameter for the Start attribute, so Im stuck with completely suplicating the component with a condition, eg/ <Component Id="ServiceDemand" Guid="{E204A71D-B0EB-4af0-96DB-9823605050C7}" > <Condition>SERVICESTART="demand"</Condition> ... and completely duplicating the whole component, with a different setting for Start and a different Condition. Anyone know of a more elegant solution? One where I don;t have to maintain 2 COmponents whjich do exactly the same thing except the Attribute for Start?

  • how to specify which child class this object belong to after retrieving from a hashmap?

    - by chandra wibowo
    hi everyone, i have a parent class called Course, and two child class PostgradCourse and UndergradCourse. i have a hashmap HashMap courses; i store all the postgradCourse and undergradCourse objects in the hashmap. i want to retrieve an undergradCourse object from the hashmap using the key. Course course = courses.get(courseCode); then i want to call a method in the UndergradCourse class, setUnits() method course.setUnits(); but the compiler say cannot find symbol- method setUnit() im pretty sure the problem is the compiler is looking for a method setUnit() in the Course class instead of UndergradCourse class i did this but its not working UndergradCourse course = courses.get(courseCode); results in incompatible type so how can i retrieve undergradCourse object from the hashmap as an undergradCourse object instead of course object? so then i can call a method inside the child class thanks in advance

  • [Three20] How to adjust width of TTStyledTextLabel ?

    - by Chi Zhang
    Hi I am implementing an IM app on iOS. I found that three20 library has a TTStyledTextLabel which provides cool features like showing images and url links. However I want to embed the TTStyledTextLabel in a message bubble (just like the sms app shipped with iphone does), where I need the label to adjust its size according to the text length. I found that TTStyledTextLabel can adjust its height according to its width, but I don't know how to make it shrink horizontally when the text is very short and can't fill up a whole line. Any suggestions?

  • How do you make an installer for your python program

    - by Malcolm2608
    Im new to python, but I was thinking about making a program with python to give to my friends. They don't know much about computers so if I asked them to install python by them selves they couldn't do it, but what if I could make an installer that downloads some version of python that only has what is needed for my file to run and make an exe file that would run the .py file in its own python interpreter . I also did a Google search and saw the freezing applications I could use to make the code into exe files to distribute (cx_freeze I use python 3.2), but not all of my friends have Windows computers and I rather Have my program so in each new version it auto updates by making a patch to .py file and not completely re-installing it .

  • Efficiently display file status when using background thread

    - by schmoopy
    How can i efficiently display the status of a file when using a background thread? For instance, lets say i have a 100MB file: when i do the code below via a thread (just as an example) it runs in about 1 min: foreach(byte b in file.bytes) { WriteByte(b, xxx); } But... if i want to update the user i have to use a delegate to update the UI from the main thread, the code below takes - FOREVER - literally i don't know how long im still waiting, ive created this post and its not even 30% done. int total = file.length; int current = 0; foreach(byte b in file.bytes) { current++; UpdateCurrentFileStatus(current, total); WriteByte(b, xxx); } public delegate void UpdateCurrentFileStatus(int cur, int total); public void UpdateCurrentFileStatus(int cur, int total) { // Check if invoke required, if so create instance of delegate // the update the UI if(this.InvokeRequired) { } else { UpdateUI(...) } }

  • is it posible to upload directly to remote server using SFTP on ASP.net MVC

    - by DucDigital
    Hi! I am currently develope something using asp.net MVC, im still quite not experience with it so please help me out. I have a form for user to upload Video. The current ideal concept to upload to remote server is to Upload it to to the current server, then use FTP to push it to a remote server. For me, this is not quite fast since you have to upload to current server (Time x1) and then the current server push to new server (Time x2) so it's double the time. So my idea is to make user upload it to the current server, and WHILE user is uploading, the current server add the file to DB and also send the file to the remote server at the same time using SFTP... is it posible and are there any security hole in this concept? Thank you very much

  • fprintf() within a subprogram

    - by sergio
    Im stuck when trying to write to my file within my subprogram. void new_page(float *a, float *b, float *c, int *d){ fprintf(results,"\nPage Totals: %f\t%f\t%f\t%d", *a,*b,*c,*d); } I get a warning saying "Warning: incompatible implicit declaration of built-in function 'fprinf' [enabled by default]" "error: 'results' undeclared (first use in this function)" in main fprintf works fine, its just when it comes to the subprogram/function it wont work. from my understanding it thinks that results is undeclared, so do i have to pass the name or location of the file to make it work?

  • flash.media.Sound.play takes long time to return

    - by Fire Lancer
    I'm trying to play some sounds in my flash project through action script. However for some reason in my code the call to Sound.play takes from 40ms to over 100ms in extreme cases, which is obviously more than enough to be very noticeable whenever a sound is played. This happens every time a sound is played, not just when that sound is first played, so I dont think its because the Sound object is still loading data or anything like that... At the start I have this to load the sound: class MyClass { [Embed(source='data/test_snd.mp3')] private var TestSound:Class; private var testSound:Sound;//flash.media.Sound public function MyClass() { testSound = new TestSound(); } Then im just using the play method of the sound object to play it later on. testSound.play();//seems to take a long time to return This as far as I can tell is following the same process as other Flash programs I found, however none of them seem to have this problem. Is there something that I've missed that would cause the play() method to be so slow?

  • audio error in vmware running mac os x

    - by PenguinSource
    simple synchronous loading of an audio file (.mp3) in a cocos2d app makes my vmware disconnect the sound. the error is display bottom right, saying 'error in creating sound stream; sound is disconnected' i read that it might be cause of my vmware's version (mine is 8) but I'm looking for a fix, not to downgrade to another version. before i get that error, the sound on the system works just fine (youtube, etc) the exact code im calling is.. [CDSoundEngine setMixerSampleRate: CD_SAMPLE_RATE_MID]; [[CDAudioManager sharedManager] setResignBehavior: kAMRBStopPlay autoHandle:Yes]; soundEngine = [SimpleAudioEngine sharedEngine]; [soundEngine preloadBackgroundMusic:@"somemp3.mp3"]; [soundEngine playBackgroundMusic:@"somemp3.mp3"]; maybe the bit rate is too high .. ? thanks

  • asp.net mvc route clashing with physical path in IIS7

    - by Andrew Bullock
    I'm messing about with controller organisation and I've hit a problem. If I have the following physical structure /Home/HomeController.cs /Home/Index.aspx /Home/About.aspx and I request the URI: /Home/Index I get a 403 Directory Listing Denied :( (im using a custom IControllerFactory and IViewEngine to look in this non-default path) Why is this happening? (I know the 403 is because its hitting the /Home folder, but why is it hitting the folder?) Why doesn't the UrlRoutingModule rewrite the route and let the controller pick up the request? Application_BeginRequest fires, but then it seems to pass control back to IIS to try and serve from the filesystem. Is it the UrlRoutingModule that defaults to a physical path if it exists before rewriting? Is there a way to make this work? N.B. Please don't suggest relocating my controllers etc. I know this is an obvious option, but that isn't the question ;) Using IIS7 In Integrated Mode Thanks

  • Rails - Create form fields dynamically and save them

    - by Frexuz
    Im building an ad-system where users can dynamically create 'fields' for each ad type. My models and example values: AdType: | id | name |----|----- | 1 | Hotel | 2 | Apartment AdOption: | id | ad_type_id | name |----|------------|----- | 1 | 1 | Star rating | 2 | 1 | Breakfast included? | 3 | 2 | Number of rooms AdValue: (Example after saving) | id | ad_id | ad_option_id | value |----|-------|---------------|------ | 1 | 1 | 1 (stars) | 5 | 2 | 1 | 2 (breakfast) | true Ad: (Example after saving) | id | description | etc.... |----|-----------------|-------- | 1 | very nice hotel | ....... So lets say I want to create a new ad, and I choose Hotel as the ad type. Then I need my view to dynamically create fields like this: (I'm guessing?) [Label] Star rating: [hidden_field :ad_id] [hidden_field :ad_option_id] [text_field :value] [Label] Breakfast included? [hidden_field :ad_id] [hidden_field :ad_option_id] [text_field :value] And also, how to save the values when the ad record is saved I hope this is understandable. If not just ask and I'll try to clarify.

  • RSA encrypted data block size

    - by calccrypto
    how do you store an rsa encrypted data block? the output might be significantly greater than the original input data block size, and i dont think people waste memory by padding bucket loads of 0s in front of each data block. besides, how would they be removed? or is each block stored on new lines within the file? if that is the case, how would you tell the difference between legitimate new line and a '\n' char written into the file? what am i missing? im writing the "write to file" part in python, so maybe its one of the differences between: open(file,'w') open(file,'w+b') open(file,'wb') that i dont know. or is it something else?

  • How to Add a Dynamic Layer to an Esri Map Control Programatically in WPF?

    - by Scott
    Just as the question asks. I have an Esri map control and want to add a Rastor image to the control in WPF and don't know how to do it. I see that I can add layers to the Map control, but is there a way to add a Raster image to a map control? I did find this code to turn the raster image into a Dynamic layer, but Im still lost on how to add a dynamic layer to the control it self. http://resources.esri.com/arcgisserver/apis/silverlight/index.cfm?fa=codeGalleryDetails&scriptID=16723 Thank you!

  • Is there a way to attach Ruby Net::HTTP request to a specific IP address / network interface?

    - by Dan Sosedoff
    Hello, Im looking a way to use different IP addresses for each GET request with standard Net::HTTP library. Server has 5 ip addresses and assuming that some API`s are blocking access when request limit per IP is reached. So, only way to do it - use another server. I cant find anything about it in ruby docs. For example, curl allows you to attach it to specific ip address (in PHP): $req = curl_init($url) curl_setopt($req, CURLOPT_INTERFACE, 'ip.address.goes.here'; $result = curl_exec($req); Is there any way to do it with Net::HTTP library? As alternative - CURB (ruby curl binding). But it will be the latest thing i`ll try. Suggestions / Ideas?

  • How do I correctly use generics?

    - by ninjasense
    I basically am making webrequests and recieving a JSON response. Depending on the request, I am parsing JSON request into objects I have created. The parsing is pretty much the same no matter what the object Im parsing into looks like. So I have a bunch of methods doing the same work only with different objects, I was wondering how I could accomplish this with generics? Here is an example public static ArrayList<Contact> parseContacts(String responseData) { ArrayList<Contact> Contacts = new ArrayList<Contact>(); try { JSONArray jsonContacts = new JSONArray(responseData); if (!jsonContacts.isNull(0)) { for (int i = 0; i < jsonContacts.length(); i++) { Contacts.add(new Contact(jsonContacts.getJSONObject(i))); } } } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (Exception e) { } return Contacts; }

  • Change the contents of a UITableView via a swipe?

    - by Mark
    Im currently using a UITableView like any other, and I am researching into the ability to perform a swipe gesture on the screen, which will then shift the contents of the visible table over to display new content for example: swiping right-to-left on the screen would change (via animation) the contents within each of the cells on screen to show new data. What I can do is detect a swipe on the cells, or perhaps on the UITableViewController, but what I dont know how to do two fold: 1) Change data in all cells (could you have a set of hidden views within a custom table cell that animate in and out of each cell per swipe?) 2) How can you do this to all cells? Thanks a lot Mark
