C#如何通过api获取其他程序listview控件各列的标题

C#如何通过api获取其他程序listview控件各列的标题?网上搜索到C++的代码,但我不会改写,谁有现成的C#代码发给我一份?
万分感激!

C/C++ code

void GetListViewInfo(HWND h)
{
    if(h==NULL)
    {
        return;
    }

    //目标进程ID与句柄
    DWORD PID;
    HANDLE hProcess;
    int nBufferLength=50; //缓冲区大小

    int nColCount=0;        //列数
    HWND hHeader = (HWND)::SendMessage(h,LVM_GETHEADER, 0,0);//获得标题头句柄
    if(hHeader==NULL)
    {
        return;
    }

    nColCount =(int)::SendMessage(hHeader,HDM_GETITEMCOUNT,0,0);      //获取ListView列数
    if(nColCount<=0)
        return;

    //远程虚拟空间地址
    HDITEM  *pVirtualItem;
    wchar_t *pVirtualBuffer;

    GetWindowThreadProcessId(h,&PID);
    hProcess=OpenProcess(PROCESS_ALL_ACCESS,false,PID);              //获取目标进程句柄失败
    if(!hProcess)
        return;

    //在目标进程地址空间分配内存
    pVirtualItem  =(HDITEM  *)VirtualAllocEx(hProcess, NULL, sizeof(HDITEM) , MEM_COMMIT, PAGE_READWRITE);
    pVirtualBuffer=(wchar_t *)VirtualAllocEx(hProcess, NULL, nBufferLength, MEM_COMMIT, PAGE_READWRITE);
    if ((!pVirtualItem)||(!pVirtualBuffer))
    {
        return;
    }

    CString strInfo = L"";
    for(int j=0;j<nColCount;j++)
    {
        wchar_t *buffer  =new wchar_t[nBufferLength];
        wmemset(buffer,0,nBufferLength);

        HDITEM hdItem;

        hdItem.mask=HDI_TEXT;
        hdItem.fmt=0;
        hdItem.cchTextMax=nBufferLength;
        hdItem.pszText=pVirtualBuffer;
        WriteProcessMemory(hProcess, pVirtualItem, &hdItem, sizeof(HDITEM), NULL);
        ::SendMessage(hHeader, HDM_GETITEM, (WPARAM)j, (LPARAM)(LPHDITEM)pVirtualItem);
        ReadProcessMemory(hProcess, pVirtualBuffer, buffer, nBufferLength,NULL);
        ReadProcessMemory(hProcess,pVirtualItem,(LPVOID)&hdItem,sizeof(HDITEM),NULL);

        CString strTemp(buffer);

        strInfo+=strTemp+ L" ";

        delete []b
}

4 个解决方案

#1

ReadProcessMemory是一种Hack的办法，并不能得到任何担保，它只能在当前的机器上工作。

#2

请问还有其它方法获取其他程序listview控件各列的标题吗?

我尝试修改了一下,但获取不到数据,不知问题在什么地方?

const uint PROCESS_VM_OPERATION = 0x0008;//允许函数VirtualProtectEx使用此句柄修改进程的虚拟内存

把表头结构体HDITEM换成LVITEM结构体,能取到列表的数据,不知问题在什么地方?
