DLL的调用
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 String) As String
Private Sub Command1_Click()
Dim ss As String
ss = FindPath(154, 39, 35, 210, 0, "zd/1.bmp", 2, "dl_8889888")
If ss <> "-1" Then
MsgBox (ss)
End If
End Sub
注意VB不能像DELPHI一样传递变量 赋值变量返回 所以特别做了有返回值的函数FindPath，另外传递字符串 请用PCHAR类型
2、易语言
.版本 2
.DLL命令 FindPath, 逻辑型, "LY_Cstar.dll", "FindPath"
.参数 StarX, 整数型
.参数 StarY, 整数型
.参数 StopX, 整数型
.参数 StopY, 整数型
.参数 Space, 整数型
.参数 MapSRC, 文本型
.参数 ClickXY, 整数型
.参数 sn, 文本型
.参数 outstring, 整数型, 传址
.局部变量 DD, 整数型
.局部变量 SS, 逻辑型
SS ＝ FindPath (418, 117, 170, 261, 0, “2.bmp”, 2, “dl_8889888”, DD)
.如果 (SS)
信息框 (“计算值：” ＋ 指针到文本 (DD), 0, )
.否则
信息框 (“设置参数不能到达此处：”, 0, )
COM DLL方式
3、TC
//开始按钮_点击操作
功能 开始_点击()
TS = com("DL.CStar") // 创建插件对象 com关键字必须是小写
ss= TS.FindPath(111,41,23,85,0,"C:\Users\momo\Desktop\C星寻路验证程序\pic\1004.bmp",2,"保密安全码")
辅助.消息框(ss)
功能结束
4、按键精灵
ss=Plugin.DL_Cstar.FindPath(154,39,35,210,0,"Map1.bmp",2,"dl_8889888")
MessageBox ss
5、Delphi
unit Unit2;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls;
type
TForm2 = class(TForm)
Button1: TButton;
procedure Button1Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form2: TForm2;
implementation
{$R *.dfm}
//------------------------------------------------------------------------------自动释放资源
function FindPath(StarX, StarY, StopX, StopY, Space: Integer; MapSRC: PAnsiChar;ClickXY: Integer; sn: PAnsiChar;var outstring: PAnsiChar): Boolean;stdcall;External 'zd/LY_Cstar.dll' ;//NAME 'FindPath2'
//------------------------------------------------------------------------------//
procedure TForm2.Button1Click(Sender: TObject);
var
ss:PAnsiChar;
begin
if FindPath(154,39,35,210,0,'zd/1.bmp',2,'dl_8889888',ss) then
ShowMessage(ss);
end;
end.
