MsgBox display in new thread of pcode compiled vb6 std exe

[Simi699]

Dear dzzie,

You have mentioned the following in
"Binary Reuse of VB6 P-Code Functions" link https://decoded.avast.io/davidzimmer/reusing-vb6-p-code-functions/

The allocation at offset 0x18 is only required if we wish to use built in VB file operation commands or the MsgBox function.

Can you please show an vb6 source code example of how to implement this so that I can display MsgBox
in new thread in vb6 standard exe compiled to pcode.
