能在该程序中实现象电子表格那样的输入界面，就可以解决这个问
题。
----VB虽提供了Grid网格控件，但其只具有显示输出功能，要使其
能接受输入数据，必须对它加以改造，在计算机报刊中的许多文章都
对此进行了探讨，但所用方法都不能令人满意，笔者经过摸索，找出
以下办法，供有兴趣者参考。
----首先在VB5.0环境下Form1中放上如图1所示的各控件：Text1;Grid1;
Command1;Command2;Vscroll1;Hscroll1。
图1Form1及其控件
----双击Form1打开Code窗口，编制程序代码。
Diminputcolnum,inputrownumAsInteger
PrivateSubCommand2_Click()
End
EndSub
PrivateSubForm_Activate()
Text1.SetFocus文本框获得焦点
EndSub
PrivateSubForm_Load()
Grid1.ColWidth(0)=540
Grid1.RowHeight(0)=216单元格的宽和高
inputcolnum=13
inputrownum=15表中显示的列、行数
Grid1.Cols=20
Grid1.Rows=20表中总的列、行数
HScroll1.Height=300
VScroll1.Width=300水平和垂直滚动条的高、宽度
Grid1.Height=(inputrownum 1)
(Grid1.RowHeight(0) Grid1.GridLineWidth*12)
12 HScroll1.Height
800×600象素时为12；640×480为15
Grid1.Width=(inputcolnum 1)*
(Grid1.ColWidth(0) Grid1.GridLineWidth*12)
12 VScroll1.Width
表的高、宽度
HScroll1.Width=Grid1.Width-VScroll1.Width
VScroll1.Height=Grid1.Height-HScroll1.Height
水平和垂直滚动条的宽、高度
HScroll1.Left=Grid1.Left
HScroll1.Top=Grid1.Top Grid1.Height-HScroll1.Height
水平滚动条的位置
VScroll1.Left=Grid1.Left Grid1.Width-VScroll1.Width
VScroll1.Top=Grid1.Top
垂直滚动条的位置
HScroll1.Min=1
HScroll1.Max=Grid1.Cols-inputcolnum
VScroll1.Min=1
VScroll1.Max=Grid1.Rows-inputrownum
水平和垂直滚动条的范围
Text1.Width=Grid1.ColWidth(0)
Text1.Height=Grid1.RowHeight(0)
文本框的宽、高度
Text1.Left=Grid1.Left Grid1.ColWidth(0)
Grid1.GridLineWidth*12
Text1.Top=Grid1.Top Grid1.RowHeight(0)
Grid1.GridLineWidth*12
文本框的位置
初始化赋值
Text1.Visible=True
ForI=1ToGrid1.Cols-1
Grid1.Col=I
Grid1.Row=0
Grid1.Text=Str(I)
Grid1.Col=0
Grid1.Row=I
