在使用svcutil创建WCF代理时,是否可以包含数据契约继承的接口,例如:
public class SomeType: ISometype
{
public string Name { get; set; }
}
public interface ISometype
{
public string Name { get; set; }
}

当我使用它创建代理时,在客户端创建SomeType类型但是没有创建接口,也没有继承.我尝试将接口标记为DataContract,但该属性不允许.
有可能做我想做的事吗?
我试图在UIWebView中的内容上执行一些Javascript.也许我对Javascript运行时的知识缺乏,但我对以下示例感到困惑.有关详细信息,请参阅源代码和注释:
NSString *html = [NSString stringWithFormat:@"<html><head><script type='text/javascript'>var content='the initial content';function myFunc(){return 'value of content: ' + content;}myFunc();</script></head><body>Hello blank</body></html>"];
// I would expect after this call that the variable content exists, as well as the function myFunc()
[self.webView loadHTMLString:html baseURL:nil];
// However, it appears not to. The following call returns nothing
NSString *result = [self.webView stringByEvaluatingJavaScriptFromString:@"myFunc();"];
NSLog(@"result: %@", result);
// Inserting the Javascript at this point seems to work as expected
result = [self.webView stringByEvaluatingJavaScriptFromString:@"var content='the new content';function myFunc(){return 'value of …Run Code Online (Sandbox Code Playgroud) 我已经尝试过使用Python + boto +多处理,S3cmd和J3tset,但是他们都在苦苦挣扎.

编辑:
eventlet + boto是一个有价值的解决方案,如下所述.在http://web.archive.org/web/20110520140439/http://teddziuba.com/2010/02/eventlet-asynchronous-io-for-g.html找到了一篇很好的活动参考文章

我能想到MT.有没有比MT好的PRNG?MT的哪种变体最好?
请看下面的代码:

Search</button>

当我使用这个脚本时,它所做的只是闪烁“hello world”,它不会将其保留在页面上。这和点击事件有关系吗?我试图单击按钮,然后将对象保留在页面上。
