How to read the characters in the EditTable of SysListView32 style control ?

[wangningyu]

Hello everyone ! Here I want to read one of the ListCtrl datas from other process(report style),and write them into my ListCtrl. Example this code ,I want to read the "Window Task Manager" datas(in Process Tab),and write it into my ListCtrl:

BOOL CTestDlg::OnInitDialog()
{
CDialog::OnInitDialog();
......

// TODO: Add extra initialization here
// Set the ListCtrl style
LONG lStyle = m\_ListCtrl.SendMessage(LVM\_GETEXTENDEDLISTVIEWSTYLE);
lStyle |=  LVS\_EX\_FULLROWSELECT | LVS\_EX\_GRIDLINES;
m\_ListCtrl.SendMessage(LVM\_SETEXTENDEDLISTVIEWSTYLE, 0,(LPARAM)lStyle);


// Add ListCtrl titles
m\_ListCtrl.InsertColumn(0,"Name",NULL,100, -1);
m\_ListCtrl.InsertColumn(1,"PID",NULL,60,-1);
m\_ListCtrl.InsertColumn(2,"User",NULL,120,-1);
m\_ListCtrl.InsertColumn(3,"CPU",NULL,60,-1);
return TRUE;  // return TRUE  unless you set the focus to a control

}
void CTestDlg::OnBtnRead()
{
// TODO: Add your control notification handler code here
m_ListCtrl.DeleteAllItems();

// Find window handle
HWND	hWnd,hListview;
hWnd=::FindWindow(NULL,\_T("Windows Task Manager"));   
hWnd=::FindWindowEx(hWnd,0,"#32770",0);   
hListview=::FindWindowEx(hWnd,0,\_T("SysListView32"),NULL);
if(!hListview)
{
	MessageBox("Listview handle is NULL ！");
	return;
}

int count = (int)::SendMessage(hListview,LVM\_GETITEMCOUNT,0,0);
int i,nItem;


// Get the ListView lines.
CString strTemp;
strTemp.Format("Total process :%d",count);
MessageBox(strTemp);

CString str1="";
CString str2="";
CString str3="";
CString str4="";

DWORD	pid;
HANDLE	process;
LVITEM	lvi, \*\_lvi;
char	firstitem\[512\], secitem\[512\],thirditem\[512\],fourthitem\[512\];
char	\*\_firstitem, \*\_secitem,\*\_thirditem,\*\_fourthitem;

memset(firstitem,0,512);
memset(secitem,0,512);
memset(thirditem,0,512);
memset(fourthitem,0,512);


// Get process pid.
GetWindowThreadProcessId(hListview, &pid);
process=OpenProcess(PROCESS\_VM\_OPERATION|PROCESS\_VM\_READ|
	PROCESS\_VM\_WRITE|PROCESS\_QUERY\_INFORMATION, FALSE, pid);

\_lvi=(LVITEM\*)VirtualAllocEx(process, NULL, sizeof(LVITEM),MEM\_COMMIT, PAGE\_READWRITE);
\_firstitem=(char\*)VirtualAllocEx(process, NULL, 512, MEM\_COMMIT,PAGE\_READWRITE);
\_secitem  =(char\*)VirtualAllocEx(process, NULL, 512, MEM\_COMMIT,PAGE\_READWRITE);
\_thirditem=(char\*)VirtualAllocEx(process, NULL, 512, MEM\_COMMIT,PAGE\_READWRITE);
\_fourthitem=(char\*)VirtualAllocEx(process,NULL, 512, MEM\_COMMIT,PAGE\_READWRITE);
lvi.cchTextMax=512;


// Here use degression , order with the t

Wouldn't it be easier to just get your own list via CreateToolhelp32Snapshot() and the Process32First()/Process32Next() pair?

Sorry , I don't want the list of my processes. that's only a SysListView32 Style Control of the sample code. if the edit listcontrol in other programs, how can I read the list ?

Assuming you have the window handle of the control, first send it a LVM_GETITEMCOUNT message. Then for each item, send the control a LVM_GETITEMTEXT message.

this item has two windows,you can find the editbox's handle to read text from it.
