You can automate Outlook and Word to get the job done. For example, you can automate Outlook from Excel or otherwise in VBA. Read more about that in the Automating Outlook from a Visual Basic Application article.

The Outlook object model provides the NameSpace.OpenSharedItem method which opens a shared item from a specified path or URL. This method is used to open iCalendar appointment (.ics) files, vCard (.vcf) files, and Outlook message (.msg) files. The type of object returned by this method depends on the type of shared item opened. So, you can use that method to open the MSG file from the disk and then read its properties for filling a spreadsheet.

您可以使用这样的模板字符串:

$name = "Maria";
$info["last_name"] = "Warner";

echo "Hello {$name} {$info["last_name"]}";

这将回荡您好Maria Warner

You can use template strings like this:

$name = "Maria";
$info["last_name"] = "Warner";

echo "Hello {$name} {$info["last_name"]}";

This will echo Hello Maria Warner.

PHP是否具有Python的模板字符串之类的功能?

创建一个类似的变量,

int currentIndex = 0;

每当选择列表更新时,

void _checkState(int index) {
  setState(
    () {
      for (var i = 0; i < _checkedValue.length; i++) {
        _checkedValue[i] = false;
      }
      _checkedValue[index] = true;
     currentIndex = index; //update here
    },
  );
}

此索引现在

_stateList[currentIndex]

将为您提供当前选择的状态

Create a variable like this on top

int currentIndex = 0;

Whenever a list is selected update this index

void _checkState(int index) {
  setState(
    () {
      for (var i = 0; i < _checkedValue.length; i++) {
        _checkedValue[i] = false;
      }
      _checkedValue[index] = true;
     currentIndex = index; //update here
    },
  );
}

Now

_stateList[currentIndex]

Will give you the currently selected state

您可以使用 dataTrigger 设置 来设置 maxlength 属性:

<PasswordBox x:Name="textboxPassword" BorderThickness="0" ToolTip="Enter your password" Password="password" Grid.Column="1">
    <PasswordBox.Style>
        <Style TargetType="PasswordBox" BasedOn="{StaticResource textboxpassword}">
            <Setter Property="MaxLength" Value="12" />
            <Style.Triggers>
                <DataTrigger Binding="{Binding IsChecked, ElementName=toggleUseToken}" Value="True">
                    <Setter Property="MaxLength" Value="5" />
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </PasswordBox.Style>
</PasswordBox>

You could a Style with a DataTrigger to set the MaxLength property:

<PasswordBox x:Name="textboxPassword" BorderThickness="0" ToolTip="Enter your password" Password="password" Grid.Column="1">
    <PasswordBox.Style>
        <Style TargetType="PasswordBox" BasedOn="{StaticResource textboxpassword}">
            <Setter Property="MaxLength" Value="12" />
            <Style.Triggers>
                <DataTrigger Binding="{Binding IsChecked, ElementName=toggleUseToken}" Value="True">
                    <Setter Property="MaxLength" Value="5" />
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </PasswordBox.Style>
</PasswordBox>

更新:

实际上,此解决方案不起作用。问题仅仅是因为列的大小为n,外部大小为n * 3并不意味着浏览器会选择制作3列。例如,如果只有2个项目将制作2列,因为为什么要制作3列?但是当它制作2时,最终会分发空间。因此,这不是解决方案。

以前的答案:

我确实想到了一个不良的解决方案。如果 container coolies equeries 当时我可以做到

<div id="outer">
  <div id="inner">
    <div></div>
    <div></div>
    <div></div>
  </div>
</div>

并做我可以做的,然后做Queries Queries Queries Queries Queries Queries Queries在外部上,迫使内部仅是我想要列的大小的倍数。

由于我没有容器查询,因此我可以使用媒体查询。这有点糟糕,因为我不能使用计算,并且只有在将外容器适合到页面时才有效。

显然,至少在Chrome中,当列转到单列时,边缘底设置将被忽略。

Update:

Actually this solution doesn't work. The problem is just because the column size is N and the outer size is N * 3 does not mean the browser will chose to make 3 columns. For example, if there are only 2 items it will make 2 columns because why make 3? But when it makes 2 it ends up distributing the space. So this isn't a solution AFAICT.

Previous answer:

I did think of one poor solution. If container queries worked then I could make

<div id="outer">
  <div id="inner">
    <div></div>
    <div></div>
    <div></div>
  </div>
</div>

And then do queries on outer to force inner to only be multiples of the size I want the columns.

Since I don't have container queries, then I can use media queries. It kind of sucks because I can't use calc and it only works if the out container can be fit to the page.

Apparently, at least in Chrome, when the column goes to a single column the margin-bottom setting is ignored.

您想要的是

gawk '$1=="WIDTH"'

或以稍长,更明确的形式:

gawk '$1=="WIDTH" {print $1, $2}'

在第一种形式中,条件是 $ 1 ==“ width” 而无需采取任何操作,默认操作是打印整个行。

在第二种形式中,动作更加明确。

What you want is

gawk '$1=="WIDTH"'

Or in slightly longer, more explicit form:

gawk '$1=="WIDTH" {print $1, $2}'

In the first form, the condition is $1=="WIDTH" without any action, the default action is to print out the whole line.

In the second form, the action is more explicit.

我无法真正解释原因,所以这可能是一个缺乏答案,对此表示抱歉(如果发现或某人发表评论,我会更新答案)。但是根据我的经验,我只能通过使用函数参数的自动推断来制作您想要的工作。

输入无默认值的函数,并为其他字段创建仿制值,例如键和值:

const fn = <Obj extends {}, K extends keyof Obj, V extends Obj[K]>(o: Obj, key: K, value: V) => {
  return undefined;
};

现在您可以使用三个参数调用该函数,并且推断将按预期工作:

type obj = {
  keyA: {
    propertyFromA: string;
  };
  keyB: {
    propertyFromB: string;
  };
};


fn({} as obj, "keyA", {propertyFromB: 'bar'}); //error
fn({} as obj, "keyA", {propertyFromA: 'foo'}); //success

您可能应该使用真实对象代替此铸件: {}作为obj

这是working playground

I can't really explain why, so this may be a lacking answer, sorry for that (I will update the answer if I found or someone comments). But from my experience, I only managed to make what you want work by using automatic inference from the function arguments.

Type the function without default values for the types, and create the generics for the other fields, like key and value:

const fn = <Obj extends {}, K extends keyof Obj, V extends Obj[K]>(o: Obj, key: K, value: V) => {
  return undefined;
};

Now you can call the function with the three parameters, and the inference will work as expected:

type obj = {
  keyA: {
    propertyFromA: string;
  };
  keyB: {
    propertyFromB: string;
  };
};


fn({} as obj, "keyA", {propertyFromB: 'bar'}); //error
fn({} as obj, "keyA", {propertyFromA: 'foo'}); //success

You probably should use a real object instead of this cast: {} as obj

Here is a working playground

如果您考虑一下,您的 handleonclick 做什么是返回一堆 jsx ,您认为这些 jsx 会出现在哪里,因为我们是我们的 t为他们指定任何位置?现在,如果您尝试这样的事情:

<button>{ handleOnClick('someId') }</button>

您将在屏幕上看到 h1 ,因为您指定了要渲染的地方,就在 button 元素中。

js 中的经典方法在按钮上呈现一些东西是这样的:

const handleOnClick=(e)=>{
   // create the element
   const newEle = document.createElement('h1');
   newEle.innerText = 'Hello';

   // append it inside the button
   e.target.appendChild(newEle);
}

If you think about it, what your handleOnClick doing is returning a bunch of jsx, where do you think these jsx will appear since we didn't specify any location for them? Now if you try something like this:

<button>{ handleOnClick('someId') }</button>

You will see the h1 on the screen because you specify that's where you want to render it, right inside the button element.

A classic way in js to render out something on button click is like this:

const handleOnClick=(e)=>{
   // create the element
   const newEle = document.createElement('h1');
   newEle.innerText = 'Hello';

   // append it inside the button
   e.target.appendChild(newEle);
}

#> [1] "Projects:  a, b"

如下所建议的,我感谢 ,我感谢:

x <- letters[1:2]
paste("Projects: ", toString(x))

#> [1] "Projects:  a, b"

A possible solution:

x <- letters[1:2]
paste("Projects: ", paste(x, collapse = ", "))

#> [1] "Projects:  a, b"

Or even shorter with toString, as suggested below by @ThomasIsCoding, to whom I thank:

x <- letters[1:2]
paste("Projects: ", toString(x))

#> [1] "Projects:  a, b"

删除显示的书籍列表并重写它不是问题。问题是,当您的书籍库迭代并确定每本书的读取按钮文本时,您是否会获得读取的当前价值?复选框: if(document.getElementById('read')。checked == true){,这只是最后一本书的读取状态。

相反,要跟踪每本书的读取状态,请添加读取的检查状态?当您将新书添加到库中时,复选框以及本书的其余部分信息: const read = document.getElementById('read')

。 ,将书对象保存到库: myLibrary.push(新书(标题,作者,页面,读取)); 而不是文本字符串。

然后,当书写书籍列表时,请使用 book.title book.author book.pages 和, book.read.read.read.read。 显示相应的书籍信息:

document.getElementById('addBtn').addEventListener("click", getBookFromInput);
let cards = document.querySelector('.cards');

let myLibrary = [];

function getBookFromInput(evt) {
  const title = document.getElementById('title').value;
  const author = document.getElementById('author').value;
  const pages = document.getElementById('pages').value;
  const read = document.getElementById('read').checked;
  myLibrary.push(new Book(title, author, pages, read));
  displayBooks();
}

function Book(title, author, pages, read) {
  this.title = title;
  this.author = author;
  this.pages = pages;
  this.read = read;
}

function displayBooks() {
  removeCards()

  for (let book of myLibrary) {
    let card = document.createElement('div');
    cards.appendChild(card).innerText = `Title: ${book.title}\nAuthor: ${book.author}\nPages: ${book.pages}\n`;
    card.classList.add('card');
    card.setAttribute('id', myLibrary.indexOf(book));

    let read;
    if (book.read === true) {
      read = 'Read!';
    } else {
      read = 'Not read yet!';
    }

    let readBtn = document.createElement('button');
    card.appendChild(readBtn).innerText = read;
    readBtn.classList.add('readBtn');
    readBtn.onclick = function() {
      if (readBtn.innerText === "Read!") {
        myLibrary[myLibrary.indexOf(book)].read = false;
        readBtn.innerText = "Not read yet!";
      } else {
        myLibrary[myLibrary.indexOf(book)].read = true;
        readBtn.innerHTML = "Read!";
      }
    }

    let removeBtn = document.createElement('button');
    card.appendChild(removeBtn).innerText = 'Remove';
    removeBtn.classList.add('removeBtn')

    removeBtn.onclick = function() {
      myLibrary.splice(myLibrary.indexOf(book),1);
      displayBooks();
    }
  }
}

function removeCards() {
  while (cards.lastChild) {
    cards.removeChild(cards.lastChild);
  }
}
<div class="header">
  <h1>Library</h1>

<div class="container">

    <input id="title" type="text">

  <div class="author">

    <input id="author" type="text">

  <div class="pages">
    <label for="pages">Pages:</label>
    <input id="pages" type="number">
  </div>
  <div class="read">
    <label for="read">Read?</label>
    <input id="read" type="checkbox">
  </div>
  <button id="addBtn">Add Book</button>
  <div class="cards"></div>
</div>

我还删除了书籍按钮ID,例如: removebtn.setAttribute('id','removeBtn'); ,因为ID必须是唯一的,并且您已经应用了具有相同名称的类。

Deleting the list of displayed books and rewriting it is not a problem. The problem is when iterating through your library of books and determining the read button text for each book, you're getting the current value of the Read? checkbox: if (document.getElementById('read').checked == true) {, which is simply the read status of the last book entered.

Instead, to keep track of each books read status, add the checked status of the Read? checkbox when you add the new book to the library along with the rest of the book information: const read = document.getElementById('read').checked;

Also, to make your library more adaptable and accessible, save the Book object to the library: myLibrary.push(new Book(title, author, pages, read));, rather than a text string.

Then, when writing your list of books use book.title, book.author, book.pages, and , book.read to display the corresponding book information:

document.getElementById('addBtn').addEventListener("click", getBookFromInput);
let cards = document.querySelector('.cards');

let myLibrary = [];

function getBookFromInput(evt) {
  const title = document.getElementById('title').value;
  const author = document.getElementById('author').value;
  const pages = document.getElementById('pages').value;
  const read = document.getElementById('read').checked;
  myLibrary.push(new Book(title, author, pages, read));
  displayBooks();
}

function Book(title, author, pages, read) {
  this.title = title;
  this.author = author;
  this.pages = pages;
  this.read = read;
}

function displayBooks() {
  removeCards()

  for (let book of myLibrary) {
    let card = document.createElement('div');
    cards.appendChild(card).innerText = `Title: ${book.title}\nAuthor: ${book.author}\nPages: ${book.pages}\n`;
    card.classList.add('card');
    card.setAttribute('id', myLibrary.indexOf(book));

    let read;
    if (book.read === true) {
      read = 'Read!';
    } else {
      read = 'Not read yet!';
    }

    let readBtn = document.createElement('button');
    card.appendChild(readBtn).innerText = read;
    readBtn.classList.add('readBtn');
    readBtn.onclick = function() {
      if (readBtn.innerText === "Read!") {
        myLibrary[myLibrary.indexOf(book)].read = false;
        readBtn.innerText = "Not read yet!";
      } else {
        myLibrary[myLibrary.indexOf(book)].read = true;
        readBtn.innerHTML = "Read!";
      }
    }

    let removeBtn = document.createElement('button');
    card.appendChild(removeBtn).innerText = 'Remove';
    removeBtn.classList.add('removeBtn')

    removeBtn.onclick = function() {
      myLibrary.splice(myLibrary.indexOf(book),1);
      displayBooks();
    }
  }
}

function removeCards() {
  while (cards.lastChild) {
    cards.removeChild(cards.lastChild);
  }
}
<div class="header">
  <h1>Library</h1>
</div>
<div class="container">
  <div class="title">
    <label for="title">Title:</label>
    <input id="title" type="text">

  <div class="author">
    <label for="author">Author:</label>
    <input id="author" type="text">

  <div class="pages">
    <label for="pages">Pages:</label>
    <input id="pages" type="number">
  </div>
  <div class="read">
    <label for="read">Read?</label>
    <input id="read" type="checkbox">
  </div>
  <button id="addBtn">Add Book</button>
  <div class="cards"></div>
</div>

I also removed the book button ids, for example: removeBtn.setAttribute('id', 'removeBtn'); since ids are necessarily unique and you're already applying a class with the same name.

  iso_year_week VARCHAR2(7) GENERATED ALWAYS AS (TO_CHAR(value, 'IYYY-IW'))
);

Then, if you have the data:

INSERT INTO table_name (value) VALUES (SYSDATE);

The table contains the columns:

VALUE YEAR MONTH DAY YEAR_MONTH DT ISO_YEAR_WEEK
2022-06-26 11:14:13 2022 6 26 2022-06-01 00:00:00 2022-06-26 00:00:00 2022-25

更新1亿行分区表的最佳方法是什么

您的示例没有显示W2和V2的来源,但我想它们也是np.linalg.eig的结果。在这种情况下,请注意,V2中的每一列都是特征向量。但是 v2 [i] 为您提供了一行。

之后, v2 [i] @ v2 [i] .t 是向量点产品,意思] @ v2 [i] .t))只需在矩阵的每个元素中添加标量值即可。

这就是您想要的:

neoweights = sum(np.real(np.outer(w[i] * v[:,i], v[:,i])) for i in range(7))

对于矩阵表达式,您必须小心何时以及如何使用权重进行乘法。这应该有效:
np.Real(W * V @ VT)

Your example doesn't show where w2 and v2 are coming from but I guess they are also the the result of np.linalg.eig. In that case note that each column in v2 is an eigen vector. But v2[i] gives you a row.

Following that, v2[i] @ v2[i].T is a vector dot product, meaning the whole expression neoweights += np.real(w2[i] * (v2[i] @ v2[i].T)) just adds a scalar value to every element of the matrix.

This is what you want instead:

neoweights = sum(np.real(np.outer(w[i] * v[:,i], v[:,i])) for i in range(7))

And for the matrix expression, you have to be careful when and how you do the multiplication with the weights. This should work:
np.real(w * v @ v.T)

tmp:= [] byte {0x7e} // flag start。被声明并被启动为一个数组,其中只有1个项目。它已经满了,请尝试使用 make()函数制作更大容量的切片。

这是一篇不错的文章,提供了更多详细信息。

tmp := []byte{0x7E} // Flag start. is declared and initiliazed as an array with only 1 item in it. It's already full, try making a slice with more capacity with the make() function.

That's a nice article with more details.
