问题描述
我正在尝试使用消息框,并尝试了一个简单的yes / no messagebox
,所以我编写了这段简单的代码。但是,无论我按什么按钮, chc变量始终返回1。我提供了代码,所以您可能会看到我做错了。
I was experimenting with message boxes, and tried a simple yes/no messagebox So I wrote this simple piece of code. However, the "chc" variable always returns as 1, no matter what button I press. I provided the code, so you maybe see what I did wrong. It is probably horribly wrong.
If MsgBoxResult.Yes Then
chc = 1
ElseIf MsgBoxResult.No Then
chc = 0
End If
MsgBox(chc)
推荐答案
MsgBox()
方法返回 MsgboxResult
< a href = https://docs.microsoft.com/zh-cn/dotnet/csharp/language-reference/keywords/enum rel = noreferrer>枚举,请检查该方法返回的值:
The MsgBox()
method is returning MsgboxResult
Enumeration, check the value that the method returns:
Public Sub MsgBoxExample()
Dim result As MsgBoxResult = Nothing
Dim chc As Integer
result = MsgBox("click something...", vbYesNo, "example")
If result = MsgBoxResult.Yes Then
chc = 1
ElseIf result = MsgBoxResult.No Then
chc = 0
End If
MsgBox(chc)
End Sub
