  • How to produce output using show function.

    - by wilson88
    I am trying to use sho to show the output of another function.The first function was used to do sorting, and returned a List. now I want to make a function that uses show() to display the output.This is how I had tried it only to get an error. Its to diplay the results of two the two sorted lists which used this function. map Auctioneer::compareBidList(map& one, map& two) and //**return Sorted.** void show(const char *msg, map<int, Bid*>& Sorted) { cout << msg << endl; show(Sorted); } void compare(map<int, Bid*>& sellers, map<int, Bid*>& buyers) { compare(sellers.begin(), sellers.end(), buyers.begin(),buyers.end(),compareBidList); } //my call in the main after declaration was as follows map<int, Bid*> buyers, sellers; Auctioneer auctioneer; auctioneer.compare(sellers,buyers); show(("Bids after sorting:", sellers,buyers);)

  • Does git ignore empty folders?

    - by Eno
    I created an Android project, added it to my git repo, comitted and pushed my clone to the master. Later I tried checking out the project and Eclipse complained about missing src folders. I checked my repo and the master repo and the src folders are missing (Im sure they were there when I created the project). So can someone explain what happened here? Im new to git so maybe I missed something?

  • ASP.NET output caching - dynamically update dependencies

    - by ColinE
    Hi All, I have an ASP.NET application which requires output caching. I need to invalidate the cached items when the data returned from a web service changes, so a simple duration is not good enough. I have been doing a bit of reading about cache dependencies and think I have the right idea. It looks like I will need to create a cache dependency to my web service. To associate the page output with this dependency I think I should use the following method: Response.AddCacheItemDependency(cacheKey); The thing I am struggling with is what I should add to the cache? The dependency my page has is to a single value returned by the web service. My current thinking is that I should create a Custom Cache Dependency via subclassing CacheDependency, and store the current value in the cache. I can then use Response.AddCacheItemDependency to form the dependency. I can then periodically check the value and for a NotifyDependencyChange in order to invalidate my cached HTTP response. The problem is, I need to ensure that the cache is flushed immediately, so a periodic check is not good enough. How can I ensure that my dependant object in the cache which represents the value returned by the web service is re-evaluated before the HTTP response is fetched from the cache? Regards, Colin E.

  • determine if intersection of a set with conjunction of two other sets is empty

    - by koen
    For any three given sets A, B and C: is there a way to determine (programmatically) whether there is an element of A that is part of the conjunction of B and C? example: A: all numbers greater than 3 B: all numbers lesser than 7 C: all numbers that equal 5 In this case there is an element in set A, being the number 5, that fits. I'm implementing this as specifications, so this numerical range is just an example. A, B, C could be anything.

    - by user2898598
    Hi I just noticed that if you creating a new view on jEdit, when you editing the new one, it affected the text on the original window's text as well, how could I create a New view that allow the user to duplicate data for the current shown view only and not effecting the old ones? I try to find solutions on the source code, then I find seems there are setting that related to this: http://www.jedit.org/users-guide/buffersets.html but I didn't find the selection mentioned on my setting.

  • Polish: Rendering of an empty menubar

    - by scheibenkleister
    Hi, I've recently upgraded Polish from 2.0.7 to 2.4.2, which causes a problem with the extended toolbar. Before everything works fine. But now, if the menubar doesn't contain an item/command, the menubar is partially rendered: http://img263.imageshack.us/img263/457/bugi.jpg Is that a known issue? Or has anything changed in the css definition? Thanks.

  • Android file-creation fails.

    - by Alxandr
    I use the following code to create a folder "mymir" and a file ".nomedia" (in the mymir-folder) on the sdcard of an android unit. However, somehow it fails with the exception that the folder the ".nomedia"-file is to be placed in dosn't exist. Here's the code: private String EnsureRootDir() throws IOException { File sdcard = Environment.getExternalStorageDirectory(); File mymirFolder = new File(sdcard.getAbsolutePath() + "/mymir/"); if(!mymirFolder.exists()) { File noMedia = new File(mymirFolder.getAbsolutePath() + "/.nomedia"); noMedia.mkdirs(); noMedia.createNewFile(); } return mymirFolder.getAbsolutePath(); }

  • ASP.NET - ViewState: empty placeholder generates view state

    - by Budda
    On my web-page I have PlaceHolder, not controls are loaded into it. <asp:PlaceHolder ID="PlaceHolderStatMain" runat="server"> </asp:PlaceHolder> I am looking the ViewState generated for the page, it is the following: <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUJLTg1NDkyNTUzD2QWAgIDD2QWAgIND2QWAmYPZBYCAgEPZBYCZg9kFgJmD2QWBmYPFQEYL3N0YXRfc3RhZGl1bS9sZWFndWVfV0VGZAIBDxUBGC9zdGF0X3N0YWRpdW0vbGVhZ3VlX0VFRmQCAg8VARgvc3RhdF9zdGFkaXVtL2xlYWd1ZV9GQ1VkZEuSBUr5LFL6WfCehNBJgjrq0GzwWCWN2qlU70V7LAAb" /> When I set EnableViewState to false: <asp:PlaceHolder ID="PlaceHolderStatMain" runat="server" EnableViewState="false"> </asp:PlaceHolder> The viewstate content was decreased significantly: <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUJLTg1NDkyNTUzZGTTn8Y28VwmpE/K7yPPkLFvhrqMdU8THijFW/BMFzk0tQ==" /> Question: how to remove 'useless' viewstate content without disabling viewstate for placeholder himself (I would like other control loaded into placeholder to has viewstate)? Is it possible at all? Any thought are welcome! P.S. I am using ASP.NET 4.0

  • Java appending XML data

    - by Travis
    I've already read through a few of the answers on this site but none of them worked for me. I have an XML file like this: <root> <character> <name>Volstvok</name> <charID>(omitted)</charID> <userID>(omitted)</userID> <apiKey>(omitted)</apiKey> </character> </root> I need to add another <character> somehow. I'm trying this but it does not work: public void addCharacter(String name, int id, int userID, String apiKey){ Element newCharacter = doc.createElement("character"); Element newName = doc.createElement("name"); newName.setTextContent(name); Element newID = doc.createElement("charID"); newID.setTextContent(Integer.toString(id)); Element newUserID = doc.createElement("userID"); newUserID.setTextContent(Integer.toString(userID)); Element newApiKey = doc.createElement("apiKey"); newApiKey.setTextContent(apiKey); //Setup and write newCharacter.appendChild(newName); newCharacter.appendChild(newID); newCharacter.appendChild(newUserID); newCharacter.appendChild(newApiKey); doc.getDocumentElement().appendChild(newCharacter); }

  • Matlab postpones disp calls when doing demanding calculations why is that?

    - by Reed Richards
    I am implementing an algorithm in Matlab. Among other things it calculates shortest paths etc. so its quite demanding for my old computer. I've put out disp calls through out the program to see what's happening all the time. However when starting on a particulary heavy for loop the disp seemes not to be called until the loop is over even though it comes before the loop. Why is that? I though that Matlab was really linear or am I just choking it with to many calculations and the disp calls get the lowest priority?

  • Can Hibernate default a Null String to Empty String

    - by sliver
    In our application we are pulling data from a DB2 mainframe database. If the database has "low values" in a field, hibernate sends a "null" value in the object. This occurs even if the column is defined as "not null". As we are doing XML parsing on this, Castor is having trouble with it. I would like to fix this in Hibernate. Also, all of the hibernate hbm files are generated, so we can't mess with them (they are regened from time to time.) Any way to intercept all Strings and replace nulls with ""?

  • python tkinter gui

    - by Lewis Townsend
    I'm wanting to make a small python program for yearly temperatures. I can get nearly everything working in the standard console but I'm wanting to implement it into a GUI. The program opens a csv file reads it into lists, works out the average, and min & max temps. Then on closing the application will save a summary to a new text file. I am wanting the default start up screen to show All Years. When a button is clicked it just shows that year's data. Here is a what I want it to look like. Pretty simple layout with just the 5 buttons and the out puts for each. I can make up the buttons for the top fine with: Code: class App: def __init__(self, master): frame = Frame(master) frame.pack() self.hi_there = Button(frame, text="All Years", command=self.All) self.hi_there.pack(side=LEFT) self.hi_there = Button(frame, text="2011", command=self.Y1) self.hi_there.pack(side=LEFT) self.hi_there = Button(frame, text="2012", command=self.Y2) self.hi_there.pack(side=LEFT) self.hi_there = Button(frame, text="2013", command=self.Y3) self.hi_there.pack(side=LEFT) self.hi_there = Button(frame, text="Save & Exit", command=self.Exit) self.hi_there.pack(side=LEFT) I'm not sure as to how to make the other elements, such as the title & table. I was going to post the code of the small program but decided not to. Once I have the structure/framework I think I can populate the fields & I might learn better this way. Using Python 2.7.3

  • Reloading embed PDF in a DIV (empty Accrobat Reader error popup)

    - by undef1
    Hello, I have a web application coded in C#/ASP.NET. The application basically exports a PDF file when the user click on Save. It then reloads a DIV, putting the EMBED (with the src pointing to the newly generated pdf file) in it. Sometimes the embed area just gets black and I get this window from Acrobat Reader: http://img180.imageshack.us/img180/3359/acreader.jpg. What does it mean? Has anyone ever see this?

    I have the following piece of code: var song:Sound; var sndChannel:SoundChannel; var context:SoundLoaderContext = new SoundLoaderContext(2000); function songLoad():void { song.load(new URLRequest(songs[selected]),context); sndChannel = song.play(); } Now I want to be able to check if the song is buffering or not. Is there a way to do this? Or should I approach it differently? Thanks in advance!
