Answer 1

Private Sub Text1_KeyPress(KeyAscii As Integer)
If KeyAscii = vbKeyReturn Then
Dim a, b, c
For inx = 1 To Len(Text1.Text)
If Asc(Mid(Text1.Text, inx, 1)) >= 48 And Asc(Mid(Text1.Text, inx, 1)) <= 57 Then a = a + 1
If Asc(Mid(Text1.Text, inx, 1)) >= 65 And Asc(Mid(Text1.Text, inx, 1)) <= 90 Then b = b + 1
If Asc(Mid(Text1.Text, inx, 1)) >= 97 And Asc(Mid(Text1.Text, inx, 1)) <= 122 Then c = c + 1
Next inx
MsgBox "小写字母：" & c & "个，大写字母：" & b & "个，数字：" & a & "个"
End If
End Sub
