本人在用Oicq聊天时，经常收到一些好友发给我的用文本符号描绘的图像，觉得好羡慕啊，于是一想何不自己编一个程序来解决一下这个问题呢。本人近期正好在学Vb，所以我就打算用Vb来搞定:). 首先，新建一个工程。在窗体Form1上放200个Shape控件（大量的复制粘贴，要有耐心),并让其成为一个从Shape(0)到Shape(199)的数组 .大家也可以先在窗体Form1上放一个Shape控件，然后用Load语句来完成加载。把Shape控件的FillColor属性设置为白色，FillStyle属性设置为Solid(实填充), BorderColor属性设置为黑色，BorderWidth属性设置为1，Shape属性设置为0(Rectangle),Height和Width属性设置为195。 然后，用"工具"下的"菜单编辑器"加入四个菜单项，标题分New,Save,Char,Exit,名称分别为NewMenu,SaveMenu,CharMenu和ExitMenu. 以上的准备工作完成以后，下面就来写程序代码了。首先介绍一下本程序设计的大体思想。本程序通过用鼠标来描绘图形，当按着鼠标左键在Shape控件上移动时，处在鼠标位置的Shape控件的颜色变为蓝色,当按右键时变为白色（Shape控件按20*10的方式排列）。用一个20*10的字符串数组来纪录各个Shape控件的状态，如着色则对应的数组元素为当前设置的字符串，否则为空格.当存盘时，把字符串数组写入文件。 程序的变量说明为: Dim imagearray(1 To 10, 1 To 20) As String Dim curstr As String '当前的描绘字符串 1.在Form_Load()过程中加入初始化代码,如下: Private Sub Form_Load() Dim i As Integer Dim j As Integer For i = 1 To 10 For j = 1 To 20 imagearray(i, j) = " " '把数组都清为空格 Next Next tops = (Form1.Height - 2000) \ 2 - 500 lefts = (Form1.Width - 4000) \ 2 For i = 0 To 199 Shape1(i).Top = tops + (i \ 20) * 200 Shape1(i).Left = lefts + (i Mod 20) * 200 Next '排列控件,使之按20*10排列 curstr = "*" End Sub 2.在MouseDown过程中添加如下代码: Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single) Dim i As Integer Dim j As Integer If Button = 1 Then '如果是左键 For i = 1 To 10 For j = 1 To 20 If (X >= lefts + (j - 1) * 200) And (X <= lefts + j * 200) And (Y >= tops + (i - 1) * 200) And (Y <= tops + i * 200) Then '以上判断鼠标点在哪个控件上 imagearray(i, j) = curstr '置相应的数组元素为Curstr Shape1((i - 1) * 20 + j - 1).FillColor = vbBlue '控件颜色变为蓝色 End If Next Next ElseIf Button = 2 Then '如果是右键 For i = 1 To 10 For j = 1 To 20 If (X >= lefts + (j - 1) * 200) And (X <= lefts + j * 200) And (Y >= tops + (i - 1) * 200) And (Y <= tops + i * 200) Then imagearray(i, j) = " " '置相应的数组元素为空格 Shape1((i - 1) * 20 + j - 1).FillColor = vbWhite '控件颜色变为白色 End If Next Next End If End Sub 3.在MouseDown过程添加如下代码: Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single) Dim i As Integer Dim j As Integer If Button = 1 Then '按着鼠标左键 For i = 1 To 10 For j = 1 To 20 If (X >= lefts + (j - 1) * 200) And (X <= lefts + j * 200) And (Y >= tops + (i - 1) * 200) And (Y <= tops + i * 200) Then imagearray(i, j) = curstr '置相应的数组元素为Curstr Shape1((i - 1) * 20 + j - 1).FillColor = vbBlue '控件颜色变为蓝色 End If Next Next ElseIf Button = 2 Then '按着鼠标右键 For i = 1 To 10 For j = 1 To 20 If (X >= lefts + (j - 1) * 200) And (X <= lefts + j * 200) And (Y >= tops + (i - 1) * 200) And (Y <= tops + i * 200) Then imagearray(i, j) = " " '置相应的数组元素为空格 Shape1((i - 1) * 20 + j - 1).FillColor = vbWhite '控件颜色变为白色 End If Next Next End If End Sub 4.New菜单的Click事件: Private Sub NewMenu_Click(Index As Integer) Dim i As Integer Dim j As Integer For i = 1 To 10 For j = 1 To 20 imagearray(i, j) = " " '数组全清为空格 Next Next For i = 0 To 199 Shape1(i).FillColor = vbWhite '控件的颜色全置为白色 Next End Sub 5.Char菜单的Click事件: Private Sub CharMenu_Click(Index As Integer) Dim str As String str = InputBox("请输入描绘字符串:", "输入描绘字符串:", curstr) If str <> "" Then '如输入的字符串不为空 curstr = str End If End Sub 6.Save菜单的Click事件: Private Sub SaveMenu_Click(Index As Integer) Dim i As Integer Dim j As Integer Dim fso As Object Dim ts As TextStream Dim filename As String Set fso = CreateObject("Scripting.FileSystemObject") filename = InputBox("请输入文件名:", "输入文件名:", "*.txt") '输入文件名 Set ts = fso.CreateTextFile(filename, True) For i = 1 To 10 For j = 1 To 20 ts.Write imagearray(i, j) Next ts.WriteLine '写一新行 Next End Sub 7.Exit菜单的Click事件: Private Sub ExitMenu_Click(Index As Integer) end '程序结束 End Sub 做完以上工作后就可以运行程序了,该程序只是一个简化版本,由许多可以改进的地方.以上代码大家也可到http://cattyxin.yeah.net/下载. |
