Re: how can i get the current selected item from listcontrol.

If you are using MFC, use the CListCtrl::GetNextItem(-1, LVNI_SELECTED) method.

It's considered good practice to read the documentation to confirm/verify what you read here.

We have a custom control ( similar to tree control ) in which we can insert columns. In one of the columns i want to have check boxes.

I need some pointers as in how to do it as the original developer of the control is not with us.

I think you asked this question yes(i usually remember questions) Load your picture and use WM_PAINT or WM_CTLCOLOR or WM_ERASEBKGND

you answerd always "can you tell me the code for this" yes
include atlImage.h

CImage m_Image;
m_Image.Load(filename);

<br />
m_Image.BitBlt(dc.m_hDC,CRect(0,0,800,600),CPoint(0,0));<br />
use this code in WM_PAINT <br />

Did you even bother to search for a solution? It is assumed that you will at least put forth some effort to go along with the suggestons you receive here.

You can do it by handling WM_CTLCOLOR

Follow the below steps,

CBitmap m_hBitmap; //Declare in class
m_hBitmap.LoadBitmap(filename); // Add this in Constructor
m_hBitmap.DeleteObject(); // Add this in Destructor

Use the following code in WM_CTLCOLOR handler, before the return statement

if (CTLCOLOR_DLG == nCtlColor) //nCtlColor is the 'in' parameter
{
hbr = ::CreatePatternBrush((HBITMAP)m_hBitmap.m_hObject);
}

if (CTLCOLOR_DLG == nCtlColor) //nCtlColor is the 'in' parameter
{
hbr = ::CreatePatternBrush((HBITMAP)m_hBitmap.m_hObject);
}

that will work if you have the bitmap in the resource.
if you are using the bitmap from file, then use the following code,

HBITMAP hBitmap; //Declare in Class

hBitmap = (HBITMAP)::LoadImage(NULL, "C:\\filename.bmp", IMAGE_BITMAP, 0,0,LR_LOADFROMFILE); //in Constructor

::DeleteObject(hBitmap); //in destructor

//Add in WM_CTLCOLOR handler
if (CTLCOLOR_DLG == nCtlColor)
hbr = ::CreatePatterhBrush(hBitmap);

thanks
but these are errors
'CreatePatterhBrush' : is not a member of '`global namespace''
'CreatePatterhBrush' : undeclared identifier
'=' : cannot convert from 'int' to 'struct HBRUSH__ *'

in the
hbr = ::CreatePatterhBrush(hBitmap);

It helps to spell the function correctly. Roll eyes | :rolleyes:
