在窗体上画1个命令按钮和1个文本框,其名称分别为Command1和Text1,再编写如下程序:Dim ss As StringPrivate Sub Text1_KeyPress(KeyAscii As Integer) If Chr(KeyAscii)<>"" Then ss=ss+Chr(KeyAscii)End SubPrivate Sub Command1_Click() Dim m As String,i As Integer For i=Len(ss)To 1 Step-1 m=m+Mid(ss,i,1) Next Text1.Text=UCase(m)End Sub程序运行后,在文本框中输入“Number 100”,并单击命令按钮,则文本框中显示的是( )。
