我正在阅读Allen Downey 撰写的Think Python一书.对于第4章,必须使用一套名为Swampy的模块.我已经下载并安装了它.
问题是模块是用Python 2编写的,我有Python 3(在Windows 7 RC1中).当我从Swampy运行TurtleWorld模块时,我收到有关print和exec语句的错误消息,这些语句现在是Python 3中的函数.我通过在GUI和World模块的代码中包含带有print和exec的括号来修复这些错误.我还得到一个错误,找不到Tkinter模块.事实证明,在Python 3中,模块名称拼写为小写t.
第三个错误更难:ImportError:没有名为tkFont的模块.
有没有人有任何想法,拜托?谢谢.
我应该在.spacemacs 中添加什么web-mode才能启用而不是Laravel 中php-mode的.blade.php文件?

我问的原因是我想在运行时打印应用程序资源中的文件,如下所示:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim printProcess As New Process
printProcess.StartInfo.CreateNoWindow = True
printProcess.StartInfo.FileName = "C:\Users\Geoffrey van Wyk\Documents\Countdown_Timer_Help.rtf"
printProcess.StartInfo.FileName = My.Resources.Countdown_Timer_Help
printProcess.StartInfo.Verb = "Print"
printProcess.Start()
End Sub

当我使用"C:\ Users\Geoffrey van Wyk\Documents\Countdown_Timer_Help.rtf"作为FileName的参数时,它可以工作.但是当我使用My.Resources.Countdown_Timer_Help时,它说它无法找到该文件.
或者这只能通过针对Mercurial API进行编程来实现?
无需打开Windows资源管理器 我想从Word VBA检查这个.
谢谢.
编辑:
此代码现在有效:
Set WshShell = CreateObject("WScript.Shell")
If WshShell.RegRead("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\HideFileExt") = 0 Then
MsgBox Prompt:="In Windows Explorer, set the folder options to hide file extensions of known file types." _
& vbCrLf & vbCrLf & " This prevents the file extension from appearing as part of the document number in" _
& "the document body and page headers.", Buttons:=vbOKOnly + vbCritical, Title:="Critical"
End If

使用ApplicationSettings存储WinForms RadioButtons的Checked属性
我在组合框中有三个radiobuttons.当它们不受应用程序设置的约束时,它们的行为正常.
将每个已检查的属性绑定到应用程序设置后,会发生以下情况:我必须单击未经检查的radiobutton两次才能检查它.第一次单击后,所有三个都未选中.
我也试过只绑定其中两个,但行为是一样的.
任何人都可以帮忙吗?
谢谢.
