AWS PHP SDK Version 2 S3 putObject Error

阅读更多关于 AWS PHP SDK Version 2 S3 putObject Error

问题 So the AWS php sdk 2.x library has been put out recently and I've taken a turkey day plunge into upgrading from 1.5x. My first was to upgrade my S3 backup class. I've quickly run into an error: Fatal error: Class 'EntityBody' not found in /usr/share/php/....my file here when trying to upload a zipped file to an S3 bucket. I wrote a class to abstract the writing a bit to allow for multi-region backup, so the code below references to $this are that. $response1 = $s3->create_object( $this-

Invalidating an NSTimer?

阅读更多关于 Invalidating an NSTimer?

问题 If I have an NSTimer that starts in viewdidload, where is the proper place to invalidate it when leaving that view? Is it also necessary to release it as well? 回答1: If you create a timer with NSTimer scheduledTimerWithTimeInterval... then you don't need to release it, as you don't own it. Now important thing is that the timer class retains the target, and in most cases we use self as the target. If the timer is not repetitive , then after the timer handler is completed, it automatically

问题 I've been trying to fix this for the last 48 hours, and it is driving me insane. My SDK Manager.exe flashes a cmd screen and closes in less than a second. After much searching, I finally managed to get my SDK Manager to open after adjusting android.bat, and running it as administrator. But, SDK Manager.exe was not able to find android.bat so I copied it into the android-sdk folder. SDK Manager.exe is now able to find android.bat, but it is still briefly flashing cmd and then closing. My PATH

第一步：安装JDK，并配置JDK环境变量第二步：下载安装Eclipse 上面两步网上很多就不详述了第三步：下载安装Android SDK Android SDK提供了开发Android应用程序所需的API库和构建、测试和调试Android应用程序所需的开发工具。打开 http://developer.android.com/sdk/index.html ，我们发现google提供了集成了Eclipse的Android Developer Tools，因为我们这次是已经下载了Eclipse，所以我们选择单独下载Android SDK。下载后双击安装，指定Android SDK的安装目录，为了方便使用Android SDK包含的开发工具，我们在系统环境变量中的Path设置Android SDK的安装目录下的tools目录。在Android SDK的安装目录下，双击“SDK Manager.exe”，打开Android SDK Manager，Android SDK Manage负责下载或更新不同版本的SDK包，我们看到默认安装的Android SDK Manager只安装了一个版本的sdk tools。打开Android SDK Manager，它会获取可安装的sdk版本，但是国内有墙，有时候会出现获取失败的情况。从弹出的log窗口中，我们可以看到连接 “ https:

Windows phone 7开发环境搭建

转载自： http://www.cnblogs.com/randylee/archive/2010/03/23/1692715.html Windows phone 7终于发布了，其SDK也同时发布，SDK所依赖的环境要求比较高。也同时都是微软的新产品。如果要想安装布署上SDK的话，必须符合以下要求： 1.操作系统：win7或vista。我这里使用的是win7旗舰版 2.开发工具：visual studio2010 3.开发SDK：Microsoft Windows Phone Developer Tool Beta(目前好像只有英文版) 一.操作系统安装：对于mobile的开发，一般都是在XP下的，所以我这里就需要安装双系统。对于用光盘安装双系统来说是很简单的，但是在没有win7光盘的情况下，安装win7还是需要一些方法的。在安装过程中win7也给我带来了一些惊喜。比如安装方便，速度快，没有那么多的设置需要手工干预等。 1.USB方式安装，对于主板支持USB启动的电脑来说，用移动硬盘或U盘都是很方便的，网上也有很多安装的方法。 2.硬盘安装，我的主板因为不支持USB启动，所以只好用这种方法了。我在网上找到了一种比较简单快捷的方法分享出来。 a.用虚拟光驱或解压缩win7的iso文件。把里面的所有文件拷出来。 b.下载HDD Installer.exe /Files
