如何使用OCX调用DLL? [英] How to call a DLL using an OCX?

问题描述

你好！
我已经用C ++中的MFC ActiveX向导创建了一个.ocx.现在，我有一个.dll，我想用.ocx调用.dll.那么，怎么办?

非常感谢您吗? )

您还可以使用环境变量LIB. DLL必须在PATH中.

您需要ocx的.tlh(类型库头)文件.
即使用excel:

#include "EXCEL8.tlh"
void doanythingwithexcel()
{
  Excel::_ApplicationPtr  excelapp;
  if(S_OK==excelapp.CreateInstance(__TEXT("Excel.Application"))
  {
    excelapp->Visible = 1;
    MessageBox(0,__TEXT("close excel?"),__TEXT("???"),MB_OK);
    excelapp->Quit();
  }
}

Hello!
I have created an .ocx with MFC ActiveX Wizard in C++. Now, I have a .dll, I want to call the .dll with the .ocx. So,how to do?

Thank you very much?

解决方案

You can simply #include the header file defining the functions you need and use #pragma comment(lib, "YOUR_PATH\YOUR_LIB.lib")

You also could use the environment variable LIB. The DLL must be in the PATH.

You need the .tlh (Type Library Header) file of your ocx.
i.e. with excel:

#include "EXCEL8.tlh"
void doanythingwithexcel()
{
  Excel::_ApplicationPtr  excelapp;
  if(S_OK==excelapp.CreateInstance(__TEXT("Excel.Application"))
  {
    excelapp->Visible = 1;
    MessageBox(0,__TEXT("close excel?"),__TEXT("???"),MB_OK);
    excelapp->Quit();
  }
}
