简述VB支持哪些循环结构？

Answer 1

for.....next
for ...each...next
do while...loop

楼上应该还在说一个 if 循环 虽然if不是标准的循环语句，而是条件判定语句，但是也可以实现循环的比如这样

Private Sub Form_Load()
Dim n As Integer

HJonny:
If n <> 3 Then
n = n + 1
MsgBox "第" & n & "次循环"
GoTo HJonny
End If
End Sub

Answer 2

for.....next
for ...each...next
do while...loop
while...wend

do until....loop

Answer 5
