VC++中如何应用porttalk
|
||
|
有个实验，是控制一个电动台做旋转运动（这部分VC++源代码由产品的制造商提供），从而给实验动物刺激，同时采集动物的脑电。我们想在旋转运动的开始和结束的时候，分别给并口一秒钟的高电平，以便在脑电信号采集系统上打上同步标记。我们做了一个并口的流水灯以验证并口操作的可靠性。用C++bulider 6.0时，利用PortTalk能控制流水灯工作；但用VC++ 6.0时，报错。因电动台的源码是VC++ 6.0，所以想请教高手。谢谢！ 下面是单纯的并口操作验证： 1、用C++bulider时，在工程目录下拷进这两个文件：PortTalk.sys; PortTalk.h。在Form中添加一个按键（功能为：使并口输出脉宽为1秒的高电平），并在Form中添加了并口初始化（因为计算机开机时并口各数据位是高电平，初始化就是将所有数据位置低）。程序运行正常，流水灯的开闭正常。 2、用VC++时，操作同上，但编译时报错。想请问一下，在VC++下如何使用PortTalk ？网上没说PortTalk不能用于VC++呀 --------------------Configuration: fang1 - Win32 Debug-------------------- Compiling resources...

谢谢您的回复，不过头文件是加上了的。附上C++源码，除 #include "PortTalk.h" 和最后面的按键响应函数，其他的都是自动生成的。请帮忙分析，谢谢！ // fang1Dlg.cpp : implementation file // #include "stdafx.h" #include "fang1.h" #include "fang1Dlg.h" #include "PortTalk.h" #ifdef _DEBUG #define new DEBUG_NEW #undef THIS_FILE static char THIS_FILE[] = __FILE__; #endif ///////////////////////////////////////////////////////////////////////////// // CAboutDlg dialog used for App About class CAboutDlg : public CDialog { public: CAboutDlg(); // Dialog Data //{{AFX_DATA(CAboutDlg) enum { IDD = IDD_ABOUTBOX }; //}}AFX_DATA // ClassWizard generated virtual function overrides //{{AFX_VIRTUAL(CAboutDlg) protected: virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support //}}AFX_VIRTUAL // Implementation protected: //{{AFX_MSG(CAboutDlg) //}}AFX_MSG DECLARE_MESSAGE_MAP() }; CAboutDlg::CAboutDlg() : CDialog(CAboutDlg::IDD) { //{{AFX_DATA_INIT(CAboutDlg) //}}AFX_DATA_INIT } void CAboutDlg:  oDataExchange(CDataExchange* pDX){ CDialog: oDataExchange(pDX);//{{AFX_DATA_MAP(CAboutDlg) //}}AFX_DATA_MAP } BEGIN_MESSAGE_MAP(CAboutDlg, CDialog) //{{AFX_MSG_MAP(CAboutDlg) // No message handlers //}}AFX_MSG_MAP END_MESSAGE_MAP() ///////////////////////////////////////////////////////////////////////////// // CFang1Dlg dialog CFang1Dlg::CFang1Dlg(CWnd* pParent /*=NULL*/) : CDialog(CFang1Dlg::IDD, pParent) { //{{AFX_DATA_INIT(CFang1Dlg) // NOTE: the ClassWizard will add member initialization here //}}AFX_DATA_INIT // Note that LoadIcon does not require a subsequent DestroyIcon in Win32 m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME); } void CFang1Dlg: oDataExchange(CDataExchange* pDX){ CDialog: oDataExchange(pDX);//{{AFX_DATA_MAP(CFang1Dlg) // NOTE: the ClassWizard will add DDX and DDV calls here //}}AFX_DATA_MAP } BEGIN_MESSAGE_MAP(CFang1Dlg, CDialog) //{{AFX_MSG_MAP(CFang1Dlg) ON_WM_SYSCOMMAND() ON_WM_PAINT() ON_WM_QUERYDRAGICON() ON_BN_CLICKED(IDC_BUTTON1, OnButton1) //}}AFX_MSG_MAP END_MESSAGE_MAP() ///////////////////////////////////////////////////////////////////////////// // CFang1Dlg message handlers BOOL CFang1Dlg::OnInitDialog() { CDialog::OnInitDialog(); // Add "About..." menu item to system menu. // IDM_ABOUTBOX must be in the system command range.
