问题
I am writing some code in Visual Basic 6. It also uses the Msgbox funtion. Now I searched this and I got to know that if you want to set the title of the Message box then this is the syntax:
Msgbox(<Prompt>,<Title>)
For example, I write this:
MsgBox ("Incorrect Answer!","QM")
It says:
Compile Error Expected: =
Can someone tell me what is the problem?
回答1:
With VB6, you can either request a response, and do something based on the answer, or you can simply display a message.
If you want to know what button was clicked, you need to use the function format - that is, you must use the brackets.
If you simply want to display a message, then you don't use the brackets.
So if you want to just display the message, then continue, do this:
MsgBox "Incorrect Answer!", , "QM"
But if you want to know which button the user clicked (e.g. to offer them a try again, cancel, then you need a variable, and you use the brackets to signifify that it's a function:
Dim response = MsgBox("Try again?", MsgBoxStyle.YesNo, "QM")
You can then look at the response variable to find out which button the user clicked.
