selecting item in listview

if (hProcess == IntPtr.Zero)

// Allocate a buffer in the remote process

if (lpRemoteBuffer == IntPtr.Zero)
throw new SystemException("Failed to allocate memory in remote process");

// Fill in the LVITEM struct, this is in your own process
// Set the pszText member to somewhere in the remote buffer,
// For the example I used the address imediately following the LVITEM stuct
lvItem.mask = LVIF_STATE;

lvItem.state = 15;
lvItem.stateMask = LVIS_SELECTED | LVIS_FOCUSED;

// Copy the local LVITEM to the remote buffer
bSuccess = WriteProcessMemory(hProcess, lpRemoteBuffer, ref lvItem,
Marshal.SizeOf(typeof(LV_ITEM)), IntPtr.Zero);
if (!bSuccess)
throw new SystemException("Failed to write to process memory");

// Send the message to the remote window with the address of the remote buffer
SendMessage(hWnd, LVM_SETITEMSTATE, item, lpRemoteBuffer);


}
finally
{

if (lpRemoteBuffer != IntPtr.Zero)
VirtualFreeEx(hProcess, lpRemoteBuffer, 0, MEM_RELEASE);
if (hProcess != IntPtr.Zero)
CloseHandle(hProcess);
}

}
use this function like this
int pos=0;
SelectListViewItem(syslistview, pos);

pos is the position of the item you want to select

you need the constants bellow for that function

const int LVIF_STATE = 0x0008;
const int LVIS_SELECTED = 0x0002;
const int LVIS_FOCUSED = 0x0001;
const int LVM_SETITEMSTATE = LVM_FIRST + 43;

and get the select item I dont have time to try and never try to do that too if you have solution for that, post here to share with me. maybe some day I will need to do that. i’m really busy at this time but select item by position is the code i already have had. I just adapted this to your code posted for u, I think it should help you understand it better if the code is semilar your code.

the hint is in the FindWindowEx parameter

see microsoft document for that. you find the first rich text class like this >>child1= FindWindowEx(parent,0,”winclasss here”,null)

that will find the first child of parent has that class and you want find the next child in the same level and has same winclass do like this>>child2= FindWindowEx(parent,child1,”winclass here”,null)

that you tell the function FindWindowEx find second child has same winclass beginning search at first child found.
“winclass here” can be whatever window class 😮 8) ,see document for that function after my explanation, I think you will get it 😀

child1= FindWindowEx(parent,0,”winclasss here”,null) << start seach at beginning

c# code:

int userpos = SendMessage(syslistview, LVM_GETNEXTITEM, -1,(IntPtr) LVIS_FOCUSED);

define constant value:
const int LVM_GETNEXTITEM = LVM_FIRST + 12;

now you can get position of item selected use the code get item by position to get item text 🙂
