剪贴板复制粘贴的数据附带乱码,求解决.

milaoshu1020 2018-08-05 03:27:13

复制/粘贴/剪切的代码如下:

void CEgclipDlg::OnClickedButtonSet()

{

	UpdateData(TRUE);

	LPSTR pBuffer = NULL;

	if (!(pBuffer = (LPSTR)GlobalAlloc(GMEM_DDESHARE, 100 * sizeof(TCHAR)))) {

		return;

	}

	if (!OpenClipboard()) {

		MessageBox(_T("调用OpenClipboard函数打开剪切板时发生错误."), _T("错误"));

		return;

	}

	EmptyClipboard();

	strcpy_s(pBuffer, 100 * sizeof(TCHAR), (LPCSTR)(LPCTSTR)m_szSource);

	if (SetClipboardData(CF_TEXT, pBuffer)) {

		MessageBox(m_szSource, _T("复制内容"));

	}

	else {

		MessageBox(_T("复制失败."));

	}

	CloseClipboard();

}





void CEgclipDlg::OnClickedButtonGet()

{

	if (!OpenClipboard()) {

		MessageBox(_T("调用OpenClipboard函数打开剪切板时发生错误."), _T("错误"));

		return;

	}

	HGLOBAL hGlobal = GetClipboardData(CF_TEXT);

	LPTSTR pBuffer = (LPTSTR)GlobalLock(hGlobal);

	m_szDestion.Format(_T("%s"), pBuffer);

	GlobalUnlock(hGlobal);

	UpdateData(FALSE);

	CloseClipboard();

}





void CEgclipDlg::OnClickedButtonCut()

{

	UpdateData(TRUE);

	LPSTR pBuffer = NULL;

	if (!(pBuffer = (LPSTR)GlobalAlloc(GMEM_DDESHARE, 100 * sizeof(TCHAR)))) {

		return;

	}

	if (!OpenClipboard()) {

		MessageBox(_T("调用OpenClipboard函数打开剪切板时发生错误."), _T("错误"));

		return;

	}

	EmptyClipboard();

	strcpy_s(pBuffer, 100 * sizeof(TCHAR), (LPCSTR)(LPCTSTR)m_szSource);

	CString szContent = m_szSource;

	m_szSource = "";

	UpdateData(FALSE);

	if (SetClipboardData(CF_TEXT, pBuffer)) {

		MessageBox(szContent, _T("复制内容"));

	}

	else {

		MessageBox(_T("复制失败."));

	}

	CloseClipboard();

}

如果全都是中文数据的话,后边有乱码;
如果全都是英文数据的话,除了第一个字母全都是乱码;
请问如何解决?

非常感谢,照二位的提示和代码修改后,运行没有问题了:

void CEgclipDlg::OnClickedButtonSet()

{

	UpdateData(TRUE);

	LPSTR pBuffer = NULL;

	LPCTSTR pSource = (LPCTSTR)m_szSource;

	size_t nLen = (_tcslen(pSource) + 1) * sizeof(TCHAR);

	if (!(pBuffer = (LPSTR)GlobalAlloc(GMEM_DDESHARE, nLen))) {

		return;

	}

	if (!OpenClipboard()) {

		MessageBox(_T("调用OpenClipboard函数打开剪切板时发生错误."), _T("错误"));

		return;

	}

	EmptyClipboard();

	//strcpy_s(pBuffer, nLen, (LPCSTR)(LPCTSTR)m_szSource);

	memcpy(pBuffer, pSource, nLen);

	if (SetClipboardData(CF_UNICODETEXT, pBuffer)) {

		MessageBox(m_szSource, _T("复制内容"));

	}

	else {

		MessageBox(_T("复制失败."));

	}

}





void CEgclipDlg::OnClickedButtonGet()

{

	if (!OpenClipboard()) {

		MessageBox(_T("调用OpenClipboard函数打开剪切板时发生错误."), _T("错误"));

		return;

	}

	HGLOBAL hGlobal = GetClipboardData(CF_UNICODETEXT);

	LPTSTR pBuffer = (LPTSTR)GlobalLock(hGlobal);

	m_szDestion.Format(_T("%s"), pBuffer);

	GlobalUnlock(hGlobal);

	UpdateData(FALSE);

	CloseClipboard();

}





void CEgclipDlg::OnClickedButtonCut()

{

	UpdateData(TRUE);

	LPSTR pBuffer = NULL;

	LPCTSTR pSource = (LPCTSTR)m_szSource;

	size_t nLen = (_tcslen(pSource) + 1) * sizeof(TCHAR);

	if (!(pBuffer = (LPSTR)GlobalAlloc(GMEM_DDESHARE, nLen))) {

		return;

	}

	if (!OpenClipboard()) {

		MessageBox(_T("调用OpenClipboard函数打开剪切板时发生错误."), _T("错误"));

		return;

	}

	EmptyClipboard();

	memcpy(pBuffer, pSource, nLen);

	CString szContent = m_szSource;

	m_szSource = "";

	UpdateData(FALSE);

	if (SetClipboardData(CF_UNICODETEXT, pBuffer)) {

		MessageBox(szContent, _T("复制内容"));

	}

	else {

		MessageBox(_T("复制失败."));

	}

	CloseClipboard();

}

引用 8 楼 zgl7903 的回复:



BOOL CopyTextToClipBoard(LPCTSTR szStringData)

  size_t tBytesLen = (_tcslen(szStringData) + 1)  * sizeof(TCHAR); //数据字节长度

  LPTSTR hglbCopy = (LPTSTR)GlobalAlloc(GMEM_MOVEABLE | GMEM_DDESHARE | GMEM_ZEROINIT, tBytesLen); //分配内存

      CloseClipboard();



      bRet = TRUE;

    }    

  }



  return bRet;

}

谢谢,这个是复制的,有没有粘贴的代码呢?

strcpy_s(pBuffer, 100 * sizeof(TCHAR), (LPCSTR)(LPCTSTR)m_szSource);
为什么是 100 ？应该是 m_szSource 长度！
另外· 注意字符串结束符（0 ，00）

好的,我试试.

改好了,后边还是有乱码:
