How can I get across processes for listctrl title bar?-CodePudding

I can across processes listctrl rows and columns, all of the content, but can't obtain the content of the title bar, ace to know?

The following code can obtain Listctrl content of cells, but the Header I written, is not.

 WriteProcessMemory (hProcess, pHeaderItem, & amp; HeaderItem, sizeof (HDITEM), NULL); 
: : SendMessage (pHeaderCtrl - & gt; GetSafeHwnd (), LVM_GETITEMTEXT, 0, (LPARAM) pHeaderItem); 
ReadProcessMemory (hProcess, pItem ItemBuf, 512, NULL);

CodePudding user response:

You look under the Debug debugging, data are allocated space? Call the above ReadxxxMemory data correct?

CodePudding user response:

BOOL the GetItem (int nPos, HDITEM * pHeaderItem) const;

Distribution,

 pHeaderItem=(HDITEM *) VirtualAllocEx (hProcess, NULL, sizeof (HDITEM), MEM_COMMIT, PAGE_READWRITE); 
PItem=(char *) VirtualAllocEx (hProcess, NULL, 512, MEM_COMMIT, PAGE_READWRITE); 
if ((! PHeaderItem) | | (! PItem)) 
{
: : MessageBox (NULL, "unable to allocate memory!" , "wrong!" , NULL); 
} 
for (i=0; i{
HeaderItem. CchTextMax=512; 
HeaderItem. PszText=pItem; 
WriteProcessMemory (hProcess, pHeaderItem, & amp; HeaderItem, sizeof (HDITEM), NULL); 
: : SendMessage (pHeaderCtrl - & gt; GetSafeHwnd (), LVM_GETITEMTEXT, 0, (LPARAM) pHeaderItem); 
ReadProcessMemory (hProcess, pItem ItemBuf, 512, NULL); 
} 

//release the memory 
The CloseHandle (hProcess); 
VirtualFreeEx (hProcess, pHeaderItem, 0, MEM_RELEASE); 
VirtualFreeEx (hProcess, pItem, 0, MEM_RELEASE);

refer to the second floor schlafenhamster response:

BOOL the GetItem (int nPos, HDITEM * pHeaderItem) const;

Hello, this can only be used for your application, not across processes read others' dialog box

CodePudding user response:

ListCtrl title may be first to get the title bar window handle ListView_GetHeader
Then use HDM_GETITEM message read content

From "HWND HWND=: : WindowFromPoint (point);" Get HeaderCtrl hWnd!
