    在打开IE时,单击菜单栏的工具菜单,然后选择Internet选项,在弹出的窗口中选择高级选项卡,勾选安全一栏下的允许活动内容在我的计算机上的文件中运行。这样问题就解决了。

    我问了一个类似的问题,但无济于事.

    我是一名新手编程学生,我只学过一些基本技巧.部分任务是创建一个我主要完成的配方程序,只有一部分阻止我完成.

    我应该允许用户调用以前创建的文本文件(我已完成此位),然后在此之后应该显示该文件的内容供他们查看(我也做过这一点),但是用户应该能够重新计算份量,从而改变成分的数量.因此,如果用户输入:“我想要2份”并且1份的原始数量是100g,那么它现在应该输出200g.

    这真让我感到沮丧,我的老师明天希望这项工作.以下是我应该允许用户做的事情.

    用户应该能够检索配方并为不同数量的人重新计算成分.

    •程序应要求用户输入人数.

    •程序应输出:

    •食谱名称

    •新人数

    •修订后的数量,包含此人数的单位.

    我将在下面发布我的实际代码,以显示我到目前为止所做的工作,即允许用户查看和制作新配方.但缺少修订后的数量.

    如果代码混乱或无组织,我很抱歉,我是新手.

    代码到目前为止:

    创建食谱

    What would you like to do?

    1) - Enter N to enter a new recipe.

    2 - Enter V to view an exisiting recipe,

    3 - Enter E - to edit a recipe to your liking.

    4 - Or enter quit to halt the program

    N

    Okay, it looks like you want to create a new recipe. Give me a moment...

    Please enter the name of the new recipe you wish to add! bread.txt

    What would you like to do?

    1) - Enter N to enter a new recipe.

    2 - Enter V to view an exisiting recipe,

    4 - Or enter quit to halt the program

    V

    Okay, Let's proceed to let you view an existing recipe stored on the computer

    Okay, it looks like you want to view an existing recipe. Please enter the name of the recipe required. bread.txt

    This recipe makes bread.txt

    Ingrendient # 1:

    我期待着你的回复.

    解决方法:

    您的配方文件看起来像这样:

    Ingrendient # N:

    {INGREDIENT}

    {AMOUNT}

    {METRIC}

    ...

    (After N ingredients...)

    Step N:

    {INSTRUCTIONS}

    所以基本上你想要一次读取四行,丢弃第一行,然后将其余部分分配给有用的东西.

    with open(path_to_recipe) as infile:

    ingredients = []

    while True:

    try:

    sentinel = next(infile) # skip a line

    if sentinel.startswith("Step"):

    # we're past the ingredients, so

    break

    name = next(infile)

    amount = next(infile)

    metric = next(infile)

    except StopIteration:

    # you've reached the end of the file

    break

    ingredients.append({'name':name, 'amount':float(amount), 'metric':metric})

    # use a dictionary for easier access

    当我们退出with块时,成分将是一个字典列表,可以按如下方式使用:

    for ingredient in ingredients:

    scaled_volume = ingredient['amount'] * scale # double portions? etc...

    print(scaled_volume, ingredient['metric'], " ", ingredient['name'])

    # # RESULT IS:

    300g flour

    50g salt

    1l water

    你应该能够利用所有这些来完成你的任务!

    今天老周只想跟大伙们分享一个小技巧,是的,小小的技巧,很简单,保证你能学会的,要是学不会,可以考虑跳泰山。

    有些时候,我们可能会想到不要让应用程序界面上显示的内容被截屏,要阻止应用界面呈现在截图上,可以在 ApplicationView 类上找答案,因为这个行为是跟应用程序视图有直接关系的。

    我们只需要设置一个属性就成了——IsScreenCaptureEnabled,如果允许程序被捕捉到,就设置为 true,要禁止被捕捉,设置为 false 就好了。简单吧。

     

    看一个例子,先看XAML布局。

    复制代码

            <Grid Margin="15">
                <Grid.RowDefinitions>
                    <RowDefinition Height="auto"/>
                    <RowDefinition/>
                    <RowDefinition Height="auto"/>
                </Grid.RowDefinitions>
                <TextBlock Text="中国高富帅的形象代表" FontSize="25" HorizontalAlignment="Center" Margin="0,6"/>
                <Image Grid.Row="1" Margin="3" Source="Assets\1.png" />
                <CheckBox Grid.Row="2" Margin="0,8" Content="禁止被截屏" FontSize="18" HorizontalAlignment="Center" Checked="OnChecked" Unchecked="OnUnChecked"/>
            </Grid>

    复制代码

    重点是 CheckBox 控件,我处理了它的 Checked 和 UnChecked 事件,如果它被选中,就禁止应用界面被捕捉;如果没选中,就允许捕捉。

    下面是实现代码。

    复制代码

            ApplicationView appView = ApplicationView.GetForCurrentView();
            private void OnChecked(object sender, RoutedEventArgs e)
            {
                appView.IsScreenCaptureEnabled = false;
            }
    
            private void OnUnChecked(object sender, RoutedEventArgs e)
            {
                appView.IsScreenCaptureEnabled = true;
            }

    复制代码

     

    来,看看效果。首先,CheckBox 是没选中的,即允许截屏,这时候截取到的超清无水印图片如下。

     

    然后,我们选上 CheckBox 控件,再截屏,得到的是一片黑乎乎的东西。

     

    这个示例很简单,我就不提供源代码了,大家完全可以自己动手的。
