C#如何通过api获取其他程序listview控件各列的标题

[ywscr0000]

如：如何获取windows任务管理器中 “进程” 项目下的listview中的列名
称 “映像名称”、“用户名、“CPU”.....等

[ZengHD]

先查查百度有没有代码吧
你要是能把VC的代码转成C#，我可以给你一份VC的代码

VC2010测试通过
自己修改为C#的吧

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 nRowCount=0;        //行数
	nRowCount   =(int)::SendMessage(h,LVM_GETITEMCOUNT,0,0);      //获取ListView行数
	if(nRowCount<=0)
		return;
	
	int nColCount=0;        //列数
	HWND hHeader = (HWND)::SendMessage(h,LVM_GETHEADER, 0,0);
	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
	LVITEM  *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  =(LVITEM  *)VirtualAllocEx(hProcess, NULL, sizeof(LVITEM) , MEM_COMMIT, PAGE_READWRITE);
	pVirtualBuffer=(wchar_t *)VirtualAllocEx(hProcess, NULL, nBufferLength*2, MEM_COMMIT, PAGE_READWRITE);
	if ((!pVirtualItem)||(!pVirtualBuffer))
	{
		return;
	}
	
	for(int i=0;i<nRowCount;i++)
	{ 
		CString strInfo = L"";
		for(int j=0;j<nColCount;j++)
		{
			wchar_t *buffer  =new wchar_t[nBufferLength];
			wmemset(buffer,0,nBufferLength);

			LVITEM lvitem;
			lvitem.cchTextMax=nBufferLength*2;
			lvitem.iSubItem=j;
			lvitem.pszText=pVirtualBuffer;
			//核心技术:将LVITEM结构体插入目标进程里,然后通过LVM_GETITEMTEXT消息获取指定项的文本
			WriteProcessMemory(hProcess, pVirtualItem, &lvitem, sizeof(LVITEM), NULL);
			::SendMessage(h, LVM_GETITEMTEXT, (WPARAM)i, (LPARAM)pVirtualItem);
			ReadProcessMemory(hProcess, pVirtualBuffer, buffer, nBufferLength*2,NULL);

			CString strTemp(buffer);

			strInfo+=strTemp+ L" ";
			 
			delete []buffer;
		}
		AfxMessageBox(strInfo);
	}

	//释放目标进程里分配的内存
	VirtualFreeEx(hProcess,pVirtualItem  ,sizeof(LVITEM) ,MEM_RELEASE);
	VirtualFreeEx(hProcess,pVirtualBuffer,nBufferLength*2,MEM_RELEASE);
	CloseHandle(hProcess);
}

BOOL CALLBACK EnumChildProc(HWND hwndChild, LPARAM lParam) 
{ 
	TCHAR szBuffer[255];
	GetClassName(hwndChild,szBuffer,sizeof(szBuffer)); 

	CString strBuffer = L"";
	strBuffer.Format(L"%s",szBuffer);
	if(strBuffer.MakeLower()==L"#32770")
	{
		HWND h = ::FindWindowEx(hwndChild,NULL,L"BUTTON",L"结束进程(&E)");
		if(h!=NULL)
		{
			HWND hListView = ::FindWindowEx(hwndChild,NULL,L"SysListView32",NULL);
			if(hListView!=NULL)
			{
				GetListViewInfo(hListView);
				return false;
			}
		}
	}
	return true; 
}

void CtsssDlg::OnBnClickedOk()
{
	// 查找任务管理器句柄
	HWND h = 0;
	h=::FindWindow(NULL,L"Windows 任务管理器");
	if(h==NULL)
	{
		AfxMessageBox(L"请运行任务管理器");
		return;
	}

	// 遍历所有控件，找到ListView
	::EnumChildWindows(h, EnumChildProc, NULL); 
}

谢谢，ZengHD回复，不是很清楚，再问一下？

LVITEM lvitem;
lvitem.cchTextMax=nBufferLength*2;
lvitem.iSubItem=j;
lvitem.pszText=pVirtualBuffer;
//核心技术:将LVITEM结构体插入目标进程里,然后通过LVM_GETITEMTEXT消息获取指定项的文本
WriteProcessMemory(hProcess, pVirtualItem, &lvitem, sizeof(LVITEM), NULL);
::SendMessage(h, LVM_GETITEMTEXT, (WPARAM)i, (LPARAM)pVirtualItem);
ReadProcessMemory(hProcess, pVirtualBuffer, buffer, nBufferLength*2,NULL);

CString strTemp(buffer);

取得的内容应是 列表项的内容，不是列名（列名称或列标题）

哦，原来只是获取表头文字啊，你用下面的代码更换GetListViewInfo函数

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 []buffer;
	}
	AfxMessageBox(strInfo);

	//释放目标进程里分配的内存
	VirtualFreeEx(hProcess,pVirtualItem  ,sizeof(HDITEM) ,MEM_RELEASE);
	VirtualFreeEx(hProcess,pVirtualBuffer,nBufferLength,MEM_RELEASE);
	CloseHandle(hProcess);
}
