No Syntax Tip And Code Completion

[Life4gal]

I think VisualMASM should contain [Syntax Tip And Code Completion] function, but why doesn't it work for me? I'm sure I didn't choose [tools - > Options - > do not show tool tips], I haven't modified anything, but it isn't work.

Just like the code completion in this picture, but when I type [invo...] it doesn't show me that [invoke] can be used. Also not work with [MessageB...].
Could someone help me?
