【急,一个九九乘法表 窗体输出问题】
Private Sub Form1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.PaintDim i, j As Integer
For i = 1 To 9
For j = 1 To 9
Print(i & " * " & j & " = " & i * j)
Next j
Print(vbCrLf)
Next i
End Sub
提示出错: 从字符串“1 * 1 = 1”到类型“Integer”的转换无效。
这个是怎么回事啊?
