据我所知,浏览器试图使其尽可能接近您的百分比值。 但是请记住,它总是使列足够宽以显示其单元格内容 - 例如它总是足够宽以保持单词“Number”可见,即使您将其设置为仅 3%。

As far as I see browser tries to make it as close to your percentage values as possible. However keep in mind that it will always make column wide enough to show its cells content - for example it will always be wide enough to keep word "Number" visible even you've set it to be 3% only.

为每个单独的表格列设置正确的宽度?

我在这里看到问题..
在您缺少的 pastebin 代码中,请像下面的示例一样声明函数参数...

您修改后的代码:

require(["dijit/layout/BorderContainer", "dijit/layout/TabContainer",
"dijit/layout/ContentPane"], function(BorderContainer, TabContainer, ContentPane ) {
var appLayout = new BorderContainer({"design": "headline"}, 'appLayout');

此外,要求参数的顺序也应在函数参数内部匹配..

I see the problem here..
In your pastebin code you are missing do declare the function paramter like the below example...

Your modified code:

require(["dijit/layout/BorderContainer", "dijit/layout/TabContainer",
"dijit/layout/ContentPane"], function(BorderContainer, TabContainer, ContentPane ) {
var appLayout = new BorderContainer({"design": "headline"}, 'appLayout');

Also the order of the require paramters should match inside the function parameters also ..

你必须转义单引号:

$text = '<a title="L\'Oreal Pure Zone - 80ml">L\'Oreal Pure Zone</a>';

You have to escape the single quotes:

$text = '<a title="L\'Oreal Pure Zone - 80ml">L\'Oreal Pure Zone</a>';

错误输出在文本中有特殊符号

每次执行此操作时:

  client.GetItemsCompleted += 

您向事件添加订阅者,因此第二次将触发两次(第三次三次,等等)。

在完成的方法中取消订阅( -= ):

void client_GetItemsCompleted(object sender, GetItemsCompletedEventArgs e)
{
    try {
       /* .... */
    }
    finally {
        client.GetItemsCompleted -= 
            new EventHandler<GetItemsCompletedEventArgs>(client_GetItemsCompleted);
    }
}

或在每次调用之前启动客户端对象。

var client = new ...();
client.GetItemsAsync(selectedCategoryId);
client.GetItemsCompleted += 
            new EventHandler<GetItemsCompletedEventArgs>(client_GetItemsCompleted);

Everytime this is executed:

  client.GetItemsCompleted += 

You add a subscriber to the event, so the second time it will fire twice (the third time triple times, etc..).

Either unsubscrice ( -= ) in the completed method:

void client_GetItemsCompleted(object sender, GetItemsCompletedEventArgs e)
{
    try {
       /* .... */
    }
    finally {
        client.GetItemsCompleted -= 
            new EventHandler<GetItemsCompletedEventArgs>(client_GetItemsCompleted);
    }
}

or initiate the client object before every call.

var client = new ...();
client.GetItemsAsync(selectedCategoryId);
client.GetItemsCompleted += 
            new EventHandler<GetItemsCompletedEventArgs>(client_GetItemsCompleted);

多个事件处理程序触发,为什么?

NSString 是不可变的,所以你不能只添加它。 相反,您可以像这样组成您的字符串:

NSString *answerString = [NSString stringWithFormat:@"%f Cubic Feet", finalVolume];

或者

NSString *unit = @"Cubic Feet";
NSString *answerString = [NSString stringWithFormat:@"%f %@", finalVolume, unit];

创建一个可变字符串:

NSMutableString *answerString = [NSMutableString stringWithFormat:@"%f ", finalVolume];
[answerString appendString:@"Cubic Feet"];

NSString is immutable, so you cannot just add to it. Instead, you either compose your string like this:

NSString *answerString = [NSString stringWithFormat:@"%f Cubic Feet", finalVolume];

or

NSString *unit = @"Cubic Feet";
NSString *answerString = [NSString stringWithFormat:@"%f %@", finalVolume, unit];

or create a mutable one:

NSMutableString *answerString = [NSMutableString stringWithFormat:@"%f ", finalVolume];
[answerString appendString:@"Cubic Feet"];

添加到 NSString

*255 把你搞砸了。 这基本上使图像搜索无效,因为屏幕上的所有内容都会与图像匹配。 尝试更低的东西。 您不太可能需要高于 *100

此外,作为一般提示,请尝试使用您正在搜索的图像的尽可能小的版本。

The *255 is messing you up. This basically nullifies the image search, since everything on the screen will match the image. Try something lower. It's unlikely you should need higher than *100

Also, as a general tip, try using the smallest possible version of the image you're searching for.

不,目前是不可能的。 Haskell 的类型系统有一些限制,使其在大多数情况下都很有用和方便,这就是这些限制之一。 您最好的选择是使用新类型。

newtype FuncFlip r a = FuncFlip { unFuncFlip :: a -> r }

新类型只是帮助编译器知道如何正确进行类型检查和执行类型导向分派(类型类)的标签。 大概您想翻转类型参数以提供一些类型类实例。 这只是意味着无论何时您想要使用该类型类的函数,您都必须使用 FuncFlip 修饰任何特定的输入,并使用 unFuncFlip 取消修饰任何特定的输出。 这比期望的稍微冗长,但实际上并没有那么糟糕,因为它迫使您明确标识要使用的类型类的哪个实例。

您可以创建 Newtype 为此,这对您来说可能方便也可能不方便。

instance Newtype (FuncFlip r a) (a -> r) where
  pack = FuncFlip
  unpack = unFuncFlip

进一步阅读:Are there "type-level combinatos ?”

No, it is currently impossible. There are certain limitations to Haskell's type system that allow it to be useful and convenient for most cases, and this is one of those limitations. Your best alternative is to use a newtype.

newtype FuncFlip r a = FuncFlip { unFuncFlip :: a -> r }

Newtypes are simply tags to help the compiler know how to typecheck and perform type-directed dispatch (typeclasses) properly. Presumably you wanted to flip the type arguments to provide some typeclass instance. That just means that whenever you want to make use of that typeclass's functions, you have to decorate any specific inputs with FuncFlip, and undecorate any specific outputs with unFuncFlip. This is slightly more verbose than desired, but it's not actually that bad, because it forces you to explicitly identify which instance of the typeclass you want to use.

You can create an instance of Newtype for this, which may or may not turn out to be convenient for you.

instance Newtype (FuncFlip r a) (a -> r) where
  pack = FuncFlip
  unpack = unFuncFlip

尝试更准确地满足您的需求。

SET DATEFORMAT ydm
DECLARE @D DATETIME
SELECT @D = CAST('24/05/2012 09:56:06' AS DATETIME)

SELECT @D AS MYDATETIME

Try this more accurate to cater your need.

SET DATEFORMAT ydm
DECLARE @D DATETIME
SELECT @D = CAST('24/05/2012 09:56:06' AS DATETIME)

SELECT @D AS MYDATETIME

有没有办法在 SQL SERVER 2008 中将 varchar 转换为 DATETIME?

这里 是适合您的固定小提琴。

  • var h[i] = ... is invalid JavaScript.
  • 您在 jsfiddle 的“JavaScript”框架中编写的内容在 onload 中执行,因此当您提供的 HTML 被执行时,这段代码还不存在(addButton() 功能)。

    <script>
    var i = 0;
    var h = new Array();
    
    function addButton() {
        i++;
        var container = document.getElementById("check0");
    
        h[i] = document.createElement("input");
        h[i].type = 'button';
        h[i].name = 'number' + i;
        h[i].value = "number" + i;
        h[i].id = 'number' + i;
    
        h[i].onclick = function() {
            showAlert(i)
        };
    
        container.appendChild(h[i]);
    }
    
    function showAlert(number) {
        alert("You clicked Button " + number);
    }
    </script>
    
    <div id="check0">
        <input type="button" value="klick mich" id="number0" onclick="addButton()"/>
    </div>​
    

Here is the fixed fiddle for you.

  • var h[i] = ... is invalid JavaScript.
  • What you write in the "JavaScript" frame on jsfiddle is executed onload, so this code is not yet present when the HTML you provide is executed (and neither is the addButton() function).

    <script>
    var i = 0;
    var h = new Array();
    
    function addButton() {
        i++;
        var container = document.getElementById("check0");
    
        h[i] = document.createElement("input");
        h[i].type = 'button';
        h[i].name = 'number' + i;
        h[i].value = "number" + i;
        h[i].id = 'number' + i;
    
        h[i].onclick = function() {
            showAlert(i)
        };
    
        container.appendChild(h[i]);
    }
    
    function showAlert(number) {
        alert("You clicked Button " + number);
    }
    </script>
    
    <div id="check0">
        <input type="button" value="klick mich" id="number0" onclick="addButton()"/>
    </div>​

我建议使用 :before 伪选择器或 background-image 来创建箭头,而不是使用 prepend。 这是一个展示性的东西,所以它真的应该由 CSS 处理。

使用 :before 伪选择器的实时函数示例 - http:/ /jsfiddle.net/Nfw7y/

如果您需要更好地控制箭头的外观,我建议您使用 background-image图标字体

Instead of using prepend I would recommend using the :before pseduo selector or a background-image to create the arrows. This is a presentational thing so it really should be handled by CSS.

Live, functional example using the :before pseduo selector - http://jsfiddle.net/Nfw7y/

If you need more control over the look of the arrows I would recommend using a background-image or an icon font.

一般来说,这是不值得的。

无论如何,创建 Runnable 的新实例的成本不会太高。 如果是,您必须研究如何分解出初始化成本高昂的部分,并确保它们是线程安全的。

你当然也可以使用 ThreadLocal 变量,它们总体上非常有用,但在这种情况下可能不是。

In general, it isn't worth it.

The cost of creating a new instance of your Runnable can't be too high anyway. If it is, you have to look at how to factor out the parts that are expensive to initialise and make sure they are thread-safe.

You can of course also use ThreadLocal variables, which on the whole are incredibly useful but probably not in this scenario.

Runnable 的实现是否应该允许在同一个实例上并发调用 run() ?

在程序结束时,析构函数针对 static 和全局对象运行。 我没有在您的代码中看到任何一个,当然除了您使用的 cincout 。 但是您继续成功地使用它们,这表明您没有用野指针破坏它们的内存。

我会检查您是否在其他未显示的文件中有任何具有静态存储持续时间的变量,并寻找影响这些对象的缓冲区溢出。

如果您有 Linux,请尝试 valgrind。 它将捕获大多数指针错误。

At the end of your program, destructors run for static and global objects. I don't see any of either in your code, except of course for cin and cout that you use. But you continue using both successfully, which suggests that you aren't trashing their memory with a wild pointer.

I would check whether you have any variables with static storage duration in other files you haven't shown, and look for buffer overruns affecting those objects.

If you have Linux, try valgrind. It will catch most pointer errors.

尝试使用 DISTINCT 来获取结果,我还建议对表使用 JOIN 语法,而不是在表名之间使用逗号。

SELECT DISTINCT t1.ID, t1.field1, t2.field2 
FROM table1 t1
INNER JOIN table2 t2 
    ON t1.field1=t2.field1;

try using DISTINCT to get your results, also I would advise using JOIN syntax for your tables and not commas between the table names.

SELECT DISTINCT t1.ID, t1.field1, t2.field2 
FROM table1 t1
INNER JOIN table2 t2 
    ON t1.field1=t2.field1;

2个表的SQL查询

UTL_MATCH 是一种用于比较字符串以检查两个字符串的相似程度的包。 它的函数评估字符串并返回分数。 因此,您将获得的只是一个数字,指示(比如)将 ${variableName} 转换为“Farmville”或“StackOveflow”需要编辑多少次。

您不会得到的是实际差异:这两个文本字符串完全相同,除了在偏移量 123 处它将 ${variableName} 替换为“Farmville”。

这样说表明了另一种方法。 使用 INSTR()SUBSTR() 定位 ${variableName 的实例} 在您的 Domo CenterView 查询中,并使用这些偏移量来识别 v$sql.fulltext 等效项中的不同文本。 您可以使用 DBMS_LOB 包< /a>。

UTL_MATCH is a packaging for comparing strings with regards for checking how similar two strings are. Its functions evaluate strings and return scores. So all you're going to get is a number indicating (say) how many edits you need to turn ${variableName} into "Farmville" or "StackOveflow".

What you won't get is the actual differences: these two strings of text are identical except at offset 123 where it replaces ${variableName} with "Farmville".

Putting it like that suggests an alternative approach. Using INSTR() and SUBSTR() to locate instances of ${variableName} in your Domo CenterView queries and use those offsets to identify the different text in the v$sql.fulltext equivalents. You can do this with CLOB in PL/SQL with the DBMS_LOB package.

与 CLOB 一起使用的类似于 UTL_MATCH 的函数
