VBA：我如何连接这个

Question

I'been doing a macro and when I have to print a bunch of info (strings and variables) in a cell it don't compile. How is the syntax then?

Sub TEST()
  
  Dim str1, str2 As String
  st1 = "Hi"
  st2 = "are"

  MsgBox (& str1& & "como" & str2 & "you")

End Sub

Answer 1

Use Option Explicit at the top of your code. Then you will be alerted if variables are undeclared.

You declare the variable st1 as a variant, the variable st2 as a string. (if you don't write the "as string" after every variable, it will not be a string.)

In the MsgBox, you use two different variables, str1 and str2 .

Such details matter.

And, of course, you have a few too many & signs in the MsgBox and not enough space characters. Try

Option Explicit
Sub TEST()
  
  Dim st1 As String, st2 As String
  st1 = "Hi"
  st2 = "are"
  MsgBox (st1 & " como " & st2 & " you")
  

End Sub

Answer 2

First, suggest using Option Explicit as you use different variables to what you Dim (eg you declare "str1" but use "st1"). Next, str1 is declared as a variant, probably not what you intended. Try:

Option Explicit

Sub TEST()
  
  Dim str1 As String
  Dim str2 As String
  
  str1 = "Hi"
  str2 = "are"

  MsgBox (str1 & "como" & str2 & "you")

End Sub
