  • Stupid newbie c++ two-dimensional array problem.

    - by paulson scott
    I've no idea if this is too newbie or generic for stackoverlflow. Apologies if that's the case, I don't intend to waste time. I've just started working through C++ Primer Plus and I've hit a little stump. This is probably super laughable but: for (int year = 0; year < YEARS; year++) { cout << "Year " << year + 1 << ":"; for (int month = 0; month < MONTHS; month++) { absoluteTotal = (yearlyTotal[year][year] += sales[year][month]); } cout << yearlyTotal[year][year] << endl; } cout << "The total number of books sold over a period of " << YEARS << " years is: " << absoluteTotal << endl; I wish to display the total of all 3 years. The rest of the code works fine: input is fine, individual yearly output is fine but I just can't get 3 years added together for one final total. I did have the total working at one point but I didn't have the individual totals working. I messed with it and reversed the situation. I've been messing with it for God knows how long. Any idea guys? Sorry if this isn't the place!

  • 3D Animation Rotating and Translating simultaneously in WPF

    - by sklitzz
    Hi, I have ModelVisual3D of a cube. I want to translate and rotate it at the same time. I wish the center of rotation to be in the middle of the cube(the cube rotates around its own axis). But when I try to do this applying both transformations the effect is not what you would expect. Since the object is translating the center of rotation is different thus making it move and rotate in a strange way. How do I get the desired effect? Transform3DGroup transGroup = new Transform3DGroup(); DoubleAnimation cardAnimation = new DoubleAnimation(); cardAnimation.From = 0; cardAnimation.To = 3; cardAnimation.Duration = new Duration(TimeSpan.FromSeconds(2)); Transform3D transform = new TranslateTransform3D(0,0,0); transGroup.Children.Add(transform); RotateTransform3D rotateTransform = new RotateTransform3D(); AxisAngleRotation3D rotateAxis = new AxisAngleRotation3D(new Vector3D(0, 1, 0), 180); Rotation3DAnimation rotateAnimation = new Rotation3DAnimation(rotateAxis, TimeSpan.FromSeconds(2)); rotateAnimation.DecelerationRatio = 0.8; transGroup.Children.Add(rotateTransform); Model.Transform = transGroup; transform.BeginAnimation(TranslateTransform3D.OffsetXProperty, cardAnimation); rotateTransform.BeginAnimation(RotateTransform3D.RotationProperty, rotateAnimation);

  • form id renamed to aspnetForm

    - by cfdev9
    When I compile and run a web application ASP.NET appears to be renaming the id of the form on the page, from id="login" to id="aspnetForm". It's messing up my stylesheet which expects the form with login for the id. Changing the css is not an option as it was provided by a designer and I don't want to modify it at all. How do I stop aspnet doing this?

  • Virtual machine on ubuntu [closed]

    - by MITHIYA MOIZ
    I have configured virtual machine on ubuntu with the help of below article, https://help.ubuntu.com/9.04/serverguide/C/libvirt.html I managed to finish all the part except the major portion getting virtual host to talk to real network, Which I guess should be done only via bridge interface. Via virtual machine manager I try to choose any interface it gives me interface not bridged When I try to bridge the interceface eth0 as below auto br0 iface br0 inet static address 192.168.0.223 network 192.168.0.0 netmask 255.255.255.0 broadcast 192.168.0.255 gateway 192.168.0.1 bridge_ports eth0 bridge_fd 9 bridge_hello 2 bridge_maxage 12 bridge_stp off I cannot communicate with this interface to network, host server looses all the communication to network. But when I remote bridge interface from /etc/network/interfaces And configure eth0 as below it works fine The primary network interface auto eth0 iface eth0 inet static address 192.168.0.223 netmask 255.255.255.0 network 192.168.0.0 broadcast 192.168.0.255 dns-nameservers 62.215.6.51 gateway 192.168.0.1 how can i setup bridge interface correctly and how would my /etc/netwrok/interfaces file would look a like.

  • switching between one and two displays in visual studio

    - by WebDude
    Most of the time I work Visual Studio with two monitors. I setup my Visual Studio to sit nicely across both monitors with code on the one side and property windows etc. on the other. However, occasionally I need to remove into my work station from home where I only have one monitor. What ends up happening is I have to re-setup my entire workspace to be used on one monitor, and when I get back to my work station I have to undo this again to get to my optimal 2 monitor environment. Is there a way to save some set layouts in Visual Studio so I could quickly switch back and forward? Example: One Monitor Layout versus Two Monito Layout?

  • Amazone API ItemSearch returns (400) Bad Request.

    - by BuzzBubba
    I'm using a simple example from Amazon documentation for ItemSearch and I get a strange error: "The remote server returned an unexpected response: (400) Bad Request." This is the code: public static void Main() { //Remember to create an instance of the amazon service, including you Access ID. AWSECommerceServicePortTypeClient service = new AWSECommerceServicePortTypeClient(new BasicHttpBinding(), new EndpointAddress( "http://webservices.amazon.com/onca/soap?Service=AWSECommerceService")); AWSECommerceServicePortTypeClient client = new AWSECommerceServicePortTypeClient( new BasicHttpBinding(), new EndpointAddress("http://webservices.amazon.com/onca/soap?Service=AWSECommerceService")); // prepare an ItemSearch request ItemSearchRequest request = new ItemSearchRequest(); request.SearchIndex = "Books"; request.Title = "Harry+Potter"; request.ResponseGroup = new string[] { "Small" }; ItemSearch itemSearch = new ItemSearch(); itemSearch.Request = new ItemSearchRequest[] { request }; itemSearch.AWSAccessKeyId = accessKeyId; // issue the ItemSearch request try { ItemSearchResponse response = client.ItemSearch(itemSearch); // write out the results foreach (var item in response.Items[0].Item) { Console.WriteLine(item.ItemAttributes.Title); } } catch(Exception e) { Console.ForegroundColor = ConsoleColor.Red; Console.WriteLine(e.Message); Console.ForegroundColor = ConsoleColor.White; Console.WriteLine("Press any key to quit..."); Clipboard.SetText(e.Message); } Console.ReadKey(); What is wrong?

  • Launchy vs. GNOME Do vs. Kupfer

    <b>MakeTechEasier:</b> "To many people, application launchers are not really worth much attention. After all, it's just a box to type in a command, right? Perhaps that used to be it, but these days there are some tiny programs that can make a huge difference in productivity."

  • European alternatives to Dropbox?

    - by torbengb
    Dropbox is positively brilliant, but the data center is probably in the US somewhere. Since I'm in Europe, there's plenty of lag and a poor upload rate. Are there any similar services using data centers in Europe? I'm looking for a free plan (cirka 2GB), so sites like Amazon S3 aren't good answers.

  • Android: ImageView scales up source image

    - by legr3c
    I can't seem to get my ImageView to display its source image in its original size. The ImageView looks like this: <ImageView android:id="@+id/Logo" android:src="@drawable/logo" android:layout_width="wrap_content" android:layout_height="wrap_content" > </ImageView> The source image is 140 pixels wide, yet on the Nexus One's screen, which is 480 pixels wide it uses up half of the width. Using absolute values in px or dp for the width and height changes nothing. The image also looks very antialiased from the upscaling. Why is this happening and how can I prevent it?

  • [emacs] make ibuffer-visit-buffer behave like ido-switch-to-buffer?

    - by Stephen
    Is there a way to make ibuffer-visit-buffer behave like ido-switch-to-buffer (with raise-frame option)? If there is a window/frame containing the buffer I'd like emacs to take me there rather than opening the same buffer in the current window. I guess switch-to-buffer is remapped to ido-switch-to-buffer when ido-mode is turned on, so would doing something like that work in this case (remap ibuffer-visit-buffer to ido-switch-to-buffer)? Thanks

  • Handling of data truncation in FUSE

    - by Vi
    I expect any good program should do all their reads and writes in a loop until all data written/read without relying that write will write everything (even with regular files). Am I right? Implemented simple FUSE filesystem which only allows reading and writing with small buffers, very often returning that it is written less bytes that in a buffer (using -o direct_io). Some programs work, some not. Are them buggy or programs should not expect truncated writes and reads from the regular files?

  • Sorting shell items like windows explorer

    - by Roy M Klever
    Hi, I am making a bread crumb bar in Delphi and having some problems regarding sorting the dropdown of the bread crumbs. Strangely enough, even Vista is not consequent when showing these items. I have tried many ways to figure out what is system folders, what is zip files and what is normal folders. It seems like an easy task but so far I have not found any good way of doing it. One way is to use TypeDisplayName from TSHFileinfo but these are localized names so I can not be sure they will be in correct order in every language. Here is the code I use to fill the menu: bool:= IsDesktop(SelectedPIDL); if bool then OleCheck(SHGetDesktopFolder(CurFolder)) else OleCheck(DesktopShellFolder.BindToObject(SelectedPIDL, nil, IID_IShellFolder, Pointer(CurFolder))); if CurFolder.EnumObjects(0, SHCONTF_FOLDERS, EnumIDList) = NOERROR then begin while EnumIDList.Next(1, CurPidl, Fetched) = S_OK do begin FName:= GetDisplayName(CurFolder, CurPidl, SHGDN_NORMAL); Text:= GetPIDLNameForAddressBar(CurFolder, CurPidl); if bool then Text:= PSpecialFolderItem(SpecialFolders[0]).Name + '\' + Text; if Text[Length(Text)] <> '\' then Text:= Text + '\'; NewPidl:= ConcatPIDLs(SelectedPIDL, CurPidl); SHGetFileInfo(PChar(NewPidl), 0, SFI, SizeOf(SFI), SHGFI_ATTRIBUTES or SHGFI_PIDL or SHGFI_SYSICONINDEX or SHGFI_TYPENAME); n:= SFI.dwAttributes; MenuList.Add(GetAttr(n) + FName); AddMenuItem(Text, FName, SFI.iIcon); CoTaskMemFree(CurPidl); CoTaskMemFree(NewPidl); end; end; CoTaskMemFree(SelectedPIDL); Any solution for how to get the correct sorting order? It is strange there is no way in dwAttributes of TSHFileInfo to tell if a folder is a system folder. Roy M Klever

  • iPhone Development on Hackintosh

    - by espais
    My question is in regards to developing code for the iPhone / iTouch. What with Apple's transition to the Intel platform for their chip, it is obviously now possible to run their OS on a PC. So, with that, and my inherently cheap nature, I was wondering if it was possible to bypass the purchase of a refurbished Mac by running the iPhone SDK on a Hackintosh? As I am more of a hobbyist then a serious developer at present, I'd basically like to get my feet wet before fully committing to this endeavor. In the long term I know that it would be better to purchase a Mac...

  • Is there a way to upload videos to youtube from our Website?

    - by Starx
    I am developing a website, where I am allowing users to upload videos, but if the members numbers keep on increasing and they keep on uploading more videos it will be expensive for me. So I want to upload the movies to youtube instead, is this possible? By viewing some other posts here, I am thinking it is possible?
