Examples of calling C-Star Pathfinding plugins in various programming languages

DLL's call

1, VB

Public Declare Function findpath Lib "Zd/ly_cstar_vb.dll" (ByVal Starx As Integer, ByVal StarY As Integer, ByVal stopx as Integer, ByVal stopy As Integer, ByVal Space As Integer, ByVal mapsrc as String, ByVal clickxy As Integer, ByVal sn as Str ing) as String

Private Sub Command1_Click ()
Dim SS as String
SS = Findpath (154, 0, "Zd/1.bmp", 2, "dl_8889888")
If SS <> "-1" Then
MsgBox (SS)
End If
End Sub

Note that VB can not pass the variable assignment variable return like Delphi, so it makes a function Findpath with return value, and passes the string in Pchar type.

2. Easy language

. Version 2

. DLL command Findpath, logic type, "Ly_cstar.dll", "Findpath"

If you add a Minimize button to your dialog, you'll need the code below
To draw the icon. For MFC applications using the Document/view model,
This is automatically do for your by the framework.
