嗨,我正在开发一个在Windows Phone 8.1中通过共享合同共享图片的应用程序.我的代码是

DataTransferManager dataTransferManager = DataTransferManager.GetForCurrentView();
dataTransferManager.DataRequested += new TypedEventHandler<DataTransferManager, DataRequestedEventArgs>(this.DataRequested);

和

private async void DataRequested(DataTransferManager sender, DataRequestedEventArgs args)
{
    DataRequest request = args.Request;
    request.Data.Properties.Title = "Unscramble this";
    request.Data.Properties.Description = "";
    request.Data.SetText(string.Format("Scrambled word is {0} and clue is {1}. Help me to unscramble this \r\n(via Unscramble Plus for Windows Phone)",scrambledString.ToUpper(),selectedMeanings.ToUpper()));
    DataRequestDeferral deferral = request.GetDeferral();

    // Make sure we always call Complete on the deferral.
    try
    {
        //StorageFile logoFile = await Package.Current.InstalledLocation.GetFileAsync("Assets\\Logo.png");

        StorageFile imagefile = await KnownFolders.PicturesLibrary.GetFileAsync("pic.png");
        List<IStorageItem> storageItems = …

Windows 8.1附带一个名为"SlideToShutdown"的功能.我试图以编程方式调用该可执行文件.我Process.Start();在C#,Shell()VB和C中试过(void)system();.

它说错误为'C:\Windows\System32\SlideToShutdown.exe' is not recognized as an internal or external command, operable program or batch file.

但是在执行命令提示符时start C:\windows\system32\slidetoshutdown.exe它完美无缺.

这是我的C程序(名为ac)来调用它

#include <stdlib.h>
#include <stdio.h>
int main()
{
    (void)system("C:\\Windows\\System32\\SlideToShutDown.exe");
    return(0);
}

请帮我.

我有一个公式来评估

((x+y-1)*(x+y-2))/2 + x 

并获取它的字符串表示形式.所以在Java 1.7中我写了

public static void main(String[] args)
{
    int x = 99999;
    int y = 99999;
    int answer = ((x+y-1)*(x+y-2))/2 + x;
    String s = Integer.toString(answer);
    System.out.println(s);
}

并在Python 2.7中

def answer(x, y):
  z = ((x+y-1)*(x+y-2))/2 + x
  return str(z);

print(answer(99999,99999))

Java给了我一些输出,672047173而Python给了我19999400005看似Python的价值是正确的.这种差异背后的原因是什么？
