本文介绍了如何通过编程方式跨进程读取其他应用程序中ListView控件的内容，包括使用WriteProcessMemory和ReadProcessMemory函数获取ListView项的Caption，以及列举了获取Windows桌面程序和程序文件夹列表的方法。

void MyGetListViewItem(HWND hWindow,TStrings *strlist)
{
    const nMaxLen=1023;
    char szBuf[nMaxLen+1];

    int          nLVItemCount;
    DWORD        dwProcessID;
    HANDLE       hProcess;
    LVITEM       lvItemLocal;
    DWORD        dwBytesRead, dwBytesWrite;
    bool         bSuccess,bWriteOK;

    //注意：本文来自www.ccrun.com，by ccrun(老妖)，转载请注明出处。
    //为防止某些不负责任的转载者，故出此下策，在代码中加入声明，请大家原谅。

    GetWindowThreadProcessId(hWindow,&dwProcessID);
    hProcess=OpenProcess(PROCESS_ALL_ACCESS,FALSE,dwProcessID);
    if(!hProcess)  //得不到指定进程的句柄
        return;
    //在指定进程内分配存储空间
    LPVOID lpTextRemote=VirtualAllocEx(hProcess,NULL,nMaxLen+1,MEM_COMMIT,PAGE_READWRITE);
    LPVOID lpListItemRemote=VirtualAllocEx(hProcess,NULL,sizeof(LVITEM),MEM_COMMIT,PAGE_READWRITE);
    if((!lpTextRemote) || (!lpListItemRemote)) //不能在指定进程内分配存储空间
        return;

    nLVItemCount=ListView_GetItemCount(hWindow);
    strlist->Add("Welcome to www.ccrun.com");
    strlist->Add("ListView的Item总数: " + String(nLVItemCount));
    strlist->Add("---------------------------");

    for(int i=0;i<nLVItemCount;i++)
    {
        ZeroMemory(szBuf,nMaxLen+1);
        bWriteOK= WriteProcessMemory(hProcess,lpTextRemote,(LPVOID)szBuf,nMaxLen+1,(LPDWORD)&dwBytesWrite);
        if(!bWriteOK) //写内存错误
            return;
        lvItemLocal.iItem=i;
        lvItemLocal.iSubItem=0;
        lvItemLocal.mask=LVIF_TEXT;
        lvItemLocal.cchTextMax=nMaxLen;
        lvItemLocal.pszText=(LPTSTR)lpTextRemote;
        dwBytesWrite=0;
        bWriteOK=WriteProcessMemory(hProcess,lpListItemRemote,(LPVOID)&lvItemLocal,sizeof(LVITEM),(LPDWORD)&dwBytesWrite);
        if(!bWriteOK) //写内存错误
            return;

        SendMessage(hWindow,LVM_GETITEMTEXT,(WPARAM)i,(LPARAM)lpListItemRemote);
        bSuccess=ReadProcessMemory(hProcess,lpTextRemote,szBuf,nMaxLen+1,&dwBytesRead);
        //从指定进程存储空间读取文本
        if(!bSuccess) //不能在指定进程内读取文本
            return;
        strlist->Add(AnsiString(szBuf));
    }//end of for(i)
    //在指定进程内释放存储空间
    VirtualFreeEx(hProcess,lpListItemRemote,0,MEM_RELEASE);
    VirtualFreeEx(hProcess,lpTextRemote,0,MEM_RELEASE);
    //关闭指定进程句柄
    CloseHandle(hProcess);
}

调用的时候这样：
void __fastcall TForm1::Button1Click(TObject *Sender)
{
    MyGetListViewItem((void *)0x000100DC,Memo1->Lines);
}

上面的((void *)0x000100DC是我用MiniSpy取得的桌面的名柄(win2000下的桌面是个ListView)，在实际调用时换成你取得的ListView的句柄即可。并且在上面的这段代码只是获取ListView的Item的Caption的。
如
    HWND hListView;
    //....获取ListView的句柄
    MyGetListViewItem(hListView,Memo1->Lines);

如果其ViewStyle为vsReport，就要考虑读取ListView的HeadItem了。呵呵。GoodLuck.

void GetTadkList(CListBox&list)

{CString s;int i=0;

//Get first Window in window list.

CWnd* pWnd=AfxGetMainWnd();

//Walk window list.

while (pWnd)

{ // I window visible, has a caption, and does not have an owner?

if (pWnd ->IsWindowVisible () &&pWnd ->IsWindowVisible () &&

pWnd ->GetWindowTextLength () &&! pWnd ->GetOwner ())

{

//Add caption o window to list box.

pWnd ->GetWindowText(s);

list.AddString (s);

pWnd=pWnd->GetWindow (GW_HWNDNEXT);

}

使用方法：1、在工程中加入上述函数

　　　　　2、在工程中加入列表框对象list

　　　　　3、调用GetTadkList(list)函数，桌面窗口全部加在了列表框中。
