当使用 TestSuite 时,您一次向套件添加一个测试用例,您的语法应该看起来更像这样:

suite.addTest(new VolumeCompare("testCase1"));
suite.addTest(new VolumeCompare("testCase2"));
suite.addTest(new VolumeCompare("testCase3"));

基本上您没有传递要运行的测试的名称,因此它尝试运行“null”并失败。

When using a TestSuite you add test cases to your suite one testcase at a time, your syntax should look more like this:

suite.addTest(new VolumeCompare("testCase1"));
suite.addTest(new VolumeCompare("testCase2"));
suite.addTest(new VolumeCompare("testCase3"));

Basically you aren't passing the name of a test to run and so it tries to run "null" and fails.

GWT 需要源代码,因为它将其编译为 JavaScript。这些错误是因为您在应用程序的客户端中使用了未在模块文件(.gwt.xml 文件)中组织的源代码,或者您没有继承该模块文件。这就是错误所指的内容:您是否忘记继承所需的模块。仅添加源并不能帮助 GWT 找到源,还必须有一个模块文件。

为了能够使用这些源,必须存在一个模块文件,或者您必须自己创建并在模块文件中继承它。以下是有关模块的文档:http:// code.google.com/intl/nl-NL/webtoolkit/doc/1.6/DevGuideOrganizingProjects.html#DevGuideModules 虽然文档是简要介绍如何针对这种情况创建自己的模块文件。

GWT needs the sources because it compiles it to JavaScript. The errors are because you have used source code in the client side of your application that isn't organized in a module file (.gwt.xml file) or you didn't inherit the module file. This is what the error refers to: did you forget to inherit a required module. Just adding the sources will not help GWT to find the sources, there must be a module file too.

To be able to use those sources there must be a module file present or you must create on yourself and inherit it in your module file. Here is the documentation on modules: http://code.google.com/intl/nl-NL/webtoolkit/doc/1.6/DevGuideOrganizingProjects.html#DevGuideModules Although the documentation is somewhat brief on how to create your own module file for this situation.

对于这个特定问题(来自 JSON 响应的数组中的空索引),我使用前瞻断言进行了正则表达式替换。考虑到请求包含 XMLHttpRequest

request.responseText.replace(/,(?=,)/gm, ",\"\"")

这会将 ,, 转换为 ,"",,并且在序列中有更多逗号的情况下也可以工作,因此 ,,, 变为 ,"","",。之后您可以使用 JSON.parse() 。

For this specific issue (the empty indexes within the arrays from the JSON response) I did a regex replacement with a lookahead assertion. Considering that request contains the XMLHttpRequest:

request.responseText.replace(/,(?=,)/gm, ",\"\"")

This will turn ,, into ,"", and will also work in case there are more commas in sequence, so ,,, becomes ,"","",. You can use JSON.parse() afterwards.

提交消息此更改指出:

[793aaebd8024896c] 签入的一部分 [c872d55493] 切勿使用 strlen()。使用我们自己的内部 sqlite3Strlen30() ,保证永远不会溢出整数。额外的显式强制转换以避免出现令人讨厌的警告消息。 (CVS 6007) (用户: drh 分支: trunk)

The commit message that went in with this change states:

[793aaebd8024896c] part of check-in [c872d55493] Never use strlen(). Use our own internal sqlite3Strlen30() which is guaranteed to never overflow an integer. Additional explicit casts to avoid nuisance warning messages. (CVS 6007) (user: drh branch: trunk)

为什么使用“strlen30()”而不是“strlen()”?

当然,类似的东西

OutputStream out = new FileOutputStream("/path/to/your/file");
out.write(answer.getBytes());
out.close();

Sure, something like

OutputStream out = new FileOutputStream("/path/to/your/file");
out.write(answer.getBytes());
out.close();

如果您想要的只是除第一个之外的每个选择元素,则只需使用 select:gt(0)

原因 :nth-child(n+2) 不起作用是因为选择元素没有相同的父元素。 :nth-child 取决于计算同一父项的子项。

看看这个:
http://jsfiddle.net/petersendidit/MvkUP/1/

If all you want is every select element but the first one then just use select:gt(0)

The reason :nth-child(n+2) doesn't work is because the select elements do not have the same parent. :nth-child depends on counting children of the same parent.

Take a look at this:

通过将最小构建设置从 4.0 交换到 4.1 来解决。
也许 4.0 缺少一些东西。

谢谢...

Solved by swapping minimum build settings from 4.0 to 4.1.
Maybe something was missing from 4.0.

Thanks...

停止一次将所有类别加载到内存中。在加载每个类别时对其进行处理。它至少会快一个数量级,并且不会导致 OOME。

Stop loading all the categories into memory at once. Process each category as it's loaded. It will be at least an order of magnitude faster and won't cause OOMEs.

解决方案,因为 NSMutableDictionary 正在覆盖内容,我不知道为什么,所以我在函数中分配了它,

    moreTableDict = [[NSMutableDictionary alloc] init];

    [myDict setObject:countryTxt.text forKey:@"Country"];
    [myDict setObject:cityTxt.text forKey:@"City"];
    [myDict setObject:EscortsNumTxt1.text forKey:@"people"];
    [myDict setObject:fromDate.text forKey:@"Datetogo"];
    [myDict setObject:toDate.text forKey:@"Datetoreach"];

    [moreArr addObject:myDict];

这对我有用

Solution as NSMutableDictionary is overriding the content I dont know why so I allocated it within the function

    moreTableDict = [[NSMutableDictionary alloc] init];

    [myDict setObject:countryTxt.text forKey:@"Country"];
    [myDict setObject:cityTxt.text forKey:@"City"];
    [myDict setObject:EscortsNumTxt1.text forKey:@"people"];
    [myDict setObject:fromDate.text forKey:@"Datetogo"];
    [myDict setObject:toDate.text forKey:@"Datetoreach"];

    [moreArr addObject:myDict];

This works for me

我找不到任何具体内容,但 MSDN 上有以下文章讨论了响应 XNA 中的按键

这个论坛帖子在 Silverlight 中讨论了它,不幸的是,唯一的答案是 解决方法

抱歉,应该将向量结果添加到框 2 中。

结果包含大约 9 个值,但全部作为一行添加到框 2 中。

我需要生成的向量在单独的行中给出 9 个左右的值。

谢谢你们!

Sorry that should be add the vector result to box 2.

The result contains about 9 values but are all added as one line in box 2.

I need the resulting vector to give me the 9 or so values in separate lines.

Thanks guys!

您最大的错误是为此使用 BinaryFormatter 。这有很多问题。

  1. 您应该信任您反序列化的数据。在客户端-服务器应用程序中很少出现这种情况。
  2. 它使用一些内部格式,我不确定不同版本的 .net 之间甚至 .net 和 mono 之间的兼容性如何。使用具有明确定义格式的序列化器。

此用例的良好替代方案是 Json 或 Xml 序列化器。个人通常使用Json.net,但是.net也有一个内置的Json序列化器。

如果您序列化复杂的对象图,不需要版本控制并且仅在同一系统上读回它,那么 BinaryFormatter 可能是正确的选择,因此您可以信任数据。即使在这种情况下,我使用它也只是因为我不知道更好的选择,而不是因为我喜欢 BinaryFormatter


既然你现在说你传输了大量数据,我会研究一下 protobuf-net。它是一个二进制序列化器,速度非常快并且生成紧凑的数据。但您应该使用数字 ID 来注释所有属性。它的作者 Marc Gravell 在 SO 上很活跃,所以你可以期待良好的支持。

Your big mistake is using BinaryFormatter for this. This has many issues.

  1. You should trust the data you deserialize. This is rarely the case in client-server applications.
  2. It uses some internal format, and I'm not sure how compatible that is between different versions of .net or even between .net and mono. Use a serializer with a well defined format.

Good alternatives for this use-case are Json or Xml serializers. Personally usually use Json.net, but .net has also a built in Json serializier.

BinaryFormatter might be the right choice if you serialize a complex object graph, don't need versioning and only read it back on the same system, so you can trust the data. And even in that scenario I'd only use it because I know no better alternative, not because I like BinaryFormatter.


Since you now stated that you transfer a lot of data I'd look into protobuf-net. It's a binary serializer that is very fast and produces compact data. But you should annotate all your properties with numeric IDs. It's author Marc Gravell is active here on SO, so you can expect good support.
