然后复制如下代码到窗体里
Private Sub Command1_Click()
Dim i As Integer
Dim dSum As Double
dSum = 1
For i = 1 To Val(Text1.Text)
dSum = dSum * i
Next
MsgBox dSum
End Sub

“求1到10的阶乘之和”用VB怎么编程序
为了编写一个VB程序计算1到10的阶乘之和，首先定义一个函数用于计算阶乘。命名为factorial，并接收一个整数参数n。在函数内部，初始化一个变量l为1，然后使用For循环从1到n，每次将l乘以当前的循环变量i。循环结束后，将l的值作为阶乘返回。接着，在主程序中添加一个按钮控件Command1。定义一个结果变量...
