利用C编译器创建动态链接库"T1_C.dll

extern "C" __declspec (dllexport) int aufruf1 (int a);

#include <stdio.h>
#include <windows.h>
FILE *h_test;
FILE *h_trace;
extern "C" __declspec (dllexport) int aufruf1(int a)
  {
  h_test= fopen ("C:/temp/test_dll.txt","a");
  if (h_test)
  {
    fprintf(h_test, "Function 'aufruf1' was called!\n");
    fclose (h_test );
  }
  a+=100;

在一个按钮的事件的“鼠标单击”C动作中输入下面的C脚本：

#include "apdefap.h"
void OnClick(char* lpszPictureName, char* lpszObjectName, char* lpszPropertyName)
{
  #pragma code ("c:/temp/T1_C.dll")
  int aufruf1(int a);
  #pragma code ()

  int value;
  value = GetTagDouble("var1"); //Return-Type: double
  SetTagDouble("result",aufruf1(value)); //Return-Type: BOOL
}

  return a;
}; 

也是要知道接口函数啊 也是要知道接口函数啊
