vc *** 作剪贴板

写了一个例子，其中的SlxCopySingleFileToClipboard函数可以将一个文件拷贝到剪切板。代码如下：

#include <stdio.h>

#include <Windows.h>

#include <ShlObj.h>

BOOL SlxCopySingleFileToClipboard(LPCSTR lpFileToCopy)

{

    DWORD dwLength = lstrlen(lpFileToCopy) + 1

    DWORD dwBufferSize = dwLength + 1 + sizeof(DROPFILES)

    char *lpBufferAll = new char[dwBufferSize]

    if(lpBufferAll != NULL)

    {

        DROPFILES *pSlxDropFiles = (DROPFILES *)lpBufferAll

        pSlxDropFiles->fNC = FALSE

        pSlxDropFiles->pt.x = 0

        pSlxDropFiles->pt.y = 0

        pSlxDropFiles->fWide = FALSE

        pSlxDropFiles->pFiles = sizeof(DROPFILES)

        LPSTR lpFile = lpBufferAll + sizeof(DROPFILES)

        lstrcpy(lpFile, lpFileToCopy)

        lpFile[dwLength] = '\0'

        HGLOBAL hGblFiles = GlobalAlloc(GMEM_ZEROINIT | GMEM_MOVEABLE | GMEM_DDESHARE, dwBufferSize)

        if(hGblFiles != NULL)

        {

            LPSTR lpGblData = (char *)GlobalLock(hGblFiles)

            if(lpGblData != NULL)

            {

                memcpy(lpGblData, lpBufferAll, dwBufferSize)

                GlobalUnlock(hGblFiles)

            }

        }

        

        if(OpenClipboard(NULL))

        {

            EmptyClipboard()

            SetClipboardData(CF_HDROP, hGblFiles)

            CloseClipboard()

        }

        delete []lpBufferAll

        return TRUE

    }

    return FALSE

}

int main()

{

    SlxCopySingleFileToClipboard("C:\\Windows\\NOTEPAD.exe")

    return 0

}

把文本放置到剪贴板上：

CString source

//put your text in source

if(OpenClipboard())

{

HGLOBAL clipbuffer

char * buffer

EmptyClipboard()

clipbuffer = GlobalAlloc(GMEM_DDESHARE, source.GetLength()+1)

buffer = (char*)GlobalLock(clipbuffer)

strcpy(buffer, LPCSTR(source))

GlobalUnlock(clipbuffer)

SetClipboardData(CF_TEXT,clipbuffer)

CloseClipboard()

}

从剪接板上获取文本：

char * buffer

if(OpenClipboard())

{

buffer = (char*)GetClipboardData(CF_TEXT)

//do something with buffer here

//before it goes out of scope

}

CloseClipboard()

GetClipboardData(CF_TEXT)

参考MSDN GetClipboardData的用法及例子.

HGLOBAL hglb

LPTSTRlptstr

HWND hEdit = (HWND)GetDlgItem(hDlg, IDC_EDIT1)

if (!IsClipboardFormatAvailable(CF_TEXT))

return

if (!OpenClipboard(hwndMain))

//hwndMain换成你的主窗口句柄

return

hglb = GetClipboardData(CF_TEXT)

if (hglb != NULL)

{

lptstr = GlobalLock(hglb)

if (lptstr != NULL)

{

SetWindowText(hEdit, lptstr)

GlobalUnlock(hglb)

}

}

CloseClipboard()
