我用Tkinter构建了一个非常原始的GUI。这是我第一次尝试GUI,所以我很难理解发生了什么(以及语法)。以下是我所拥有的:
from __future__ import division, print_function
import os, ttk, tkFileDialog, Tkconstants
import Tkinter as tk
import datetime as dt
Tkinter = tk
# define OS version
version = '0.0.2'
class TestGUI(tk.Tk):
def __init__(s
我正在研究Unity3D和C#,并试图理解这段代码的内部工作原理。有人能给我解释一下吗?
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
/// <summary>
/// This script will shrink and grow the game object over time.
/// </summary>
public class Resizer : MonoBehaviour
{
// fields for timer support
我有两门课:
Workout.cs:
public class Workout
{
public int Id { get; set; }
public string Name { get; set; }
public ICollection<WorkoutSet> Sets { get; set; }
public DateTimeOffset FromDateTime { get; set; }
我想在输入框中使用*字符,但出现错误提示
conversion from "*" to string invalid
如何使我的输入框将键入的文本隐藏为密码字符?
以下是我的代码
Dim value As String
value = InputBox("Security Check", " Enter password", "*")
If value = "123456" Then
numr.Enabled = True
End If
End Sub
SELECT M.TradeDate, M.Expiry, M.Future
FROM MTM as M
JOIN (SELECT TradeDate, MIN(Expiry) as Expiry
FROM MTM
WHERE Code = 'GOVI'
and Type = 'F'
GROUP BY TradeDate) as T
ON M.TradeDate = T.TradeDate and M.Expiry = T.Expiry
WHERE M.Code = 'GOVI'
and
正如标题所建议的那样,我希望输入字段中的每个字母都显示在新行上,使用want循环。例如,如果有人在输入框中输入“cat”,这将被返回:
C
一个
T
到目前为止,这是我所拥有的,但目前它只显示了第一个字母。
var input = document.getElementById('userinput').value;
var i = input.length;
while (i--) {
document.getElementById('message').innerHTML = (input[i]);
}
