我试图在SAME类的另一个方法中调用方法的变量,并且由于某种原因它什么都不打印.
class Colors():
def blue(self):
var = "This is blue"
def red(self):
b = self.blue
print b.var
我也试过了 print self.blue.var
我正在编写一个实用程序(恰好在python中),它以TCL脚本的形式生成输出.给定python中的一些任意字符串变量(不是unicode),我想生成一个类似的TCL行
set s something
...将TCL变量' s'设置为该精确字符串,无论其中包含什么奇怪的字符.没有变得太奇怪,我不想让输出比需要的更麻烦.我相信一个体面的方法
如果字符串不是空的并且只包含字母数字,而某些字符.-_(但绝对不是$"{}\)那么它可以原样使用;
如果它只包含可打印字符而没有双引号或花括号(并且不以反斜杠结尾),那么只需将{}它放在一边;
否则,""在使用\转义后放置它" { } \ $ [ ] ,并\nnn转义为非打印字符.
问题:是否需要在双引号内转义的完整字符集？我在文档中找不到这个.我是否错过了一些东西(我几乎错过了(2)的字符串不能以\结尾).
我知道还有许多其他字符串可以引用 {},但似乎很难轻易识别它们.此外,看起来非打印字符(特别是换行符)可以使用(2)如果您不介意它们确实存在于TCL输出中.

我不习惯用指针代码(例如C++),也有不安全的岛屿:只有"安全"的C#.现在我想在.Net Micro Framework的C#中实现一个函数,其中紧凑性和性能非常重要.基本上,我会收集4个短裤,从而填充缓冲区(例如字节数组).让我们说每个样本都是这样的:
struct MyStruct
{
public short An1;
public short An2;
public short An3;
public short An4;
}
每个样本都是通过计时器事件收集的,因此我无法循环(有几个原因).我已经尝试了很多方法来有效地做到这一点,但表现最好的似乎是这一个:
unsafe struct MyStruct2
{
public fixed byte Buffer[Program.BufferSize];
}
unsafe class Program
{
public const int BufferSize = 0x1000;
public const int ArraySize = BufferSize / 8;
static MyStruct2 _struct2 = new MyStruct2();
static MyStruct* _structPtr;
unsafe static void Main(string[] args)

我正在开发一个具有大量颜色样式的网站,大约250行CSS来定义7种颜色方案中的一种,因此我必须尽可能地保持各种颜色规则的分组.
当我尝试堆栈与不推荐使用的CSS3 ::selection伪元素相关的选择器时,Firefox 4的最新RC表现很糟糕.
这有效:
.green ::-moz-selection {
/* 'Pure Hue' Color */
background-color: #62BA21;
color: white;
}
但是,一旦我尝试与webkit的选择器共享规则,它就会中断.
对FireFox不起作用:
.green ::selection, .green ::-moz-selection {
/* 'Pure Hue' Color */
background-color: #62BA21;
color: white;
}
我知道他们可能不会解决这个错误,因为::selection工作草案中不再存在这个错误,但我更愿意,如果我不必为了这个怪癖而放弃我的CSS.
List<CormantRadPane> panesToSave = new List<CormantRadPane>();
foreach (KeyValuePair<string, RadPaneSetting> paneState in RadControlStates.PaneStates)
{
CormantRadPane pane = Utilities.FindControlRecursive(Page, paneState.Key) as CormantRadPane;
panesToSave.Add(pane);
}
foreach (CormantRadPane pane in panesToSave)
{
RadControlSave.SavePane(pane);
}
RadControlSave.SavePane(窗格)修改RadControlStates.PaneStates集合.在这种情况下编写此代码有更好的方法吗？
编辑:每个人都请阅读我在字面上写的内容.Jimmy发布了一个我没有的明显解决方案 - 在迭代之前创建集合的副本,以便RadControlSave不会修改正在迭代的集合.

我想用c#在我的Windows窗体的文本框中使用水印？
我在stackoverflow中找到了这个链接.但我真的无法弄清楚如何在我的Windows应用程序中使用.
class WatermarkTextBox : TextBox
{
private const uint ECM_FIRST = 0x1500;
private const uint EM_SETCUEBANNER = ECM_FIRST + 1;
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, uint wParam, [MarshalAs(UnmanagedType.LPWStr)] string lParam);
private string watermarkText;
public string WatermarkText
{
get { return watermarkText; }
set
{
watermarkText = value;
SetWatermark(watermarkText);
}
}
private void SetWatermark(string watermarkText)
{
SendMessage(this.Handle, EM_SETCUEBANNER, 0, watermarkText);
}
}
请帮助如何使用SendMessage方法或建议我使用水印的任何其他(简单)方法.
