I have two questions:

1. I use CListViewCtrl with checkboxes, How can I change the size of a check box?
2. Too I have a CLsitViewCtl without checkboxes. I am handling LVN_ITEMCHANGED notification but I need a notification  when I on click in the same item.
What notification I need?

Thank You.

For the first one,
Use the resource editor to create two bitmaps, let's call them:

    IDB_MyBigCheckboxChecked
    IDB_MyBigCheckboxChecked

After setting up the listbox columns, get access to the CImageList and replace each of the "small images" with your own:

     CImageList* pIL= m_ctlList.GetImageList(  LVSIL_STATE  );
     int n= pIL->GetImageCount();  // eyeball check there should be two

Use code like this to replace them:

     CBitmap bm1, bm2;
     bm1.LoadBitmap(IDB_MyBigCheckboxChecked );
     pIL->Replace(0, &bm1, RGB(255, 255, 255)); // #1

     bm2.LoadBitmap( IDB_MyBigCheckboxChecked );
     pIL->Replace(1, &bm2, RGB(255, 255, 255)); // #2

For the second part of your question, I think you want to be notified when the item gets selected -- Is that right?

If so, make a handler got LVN_ITEMCHANGED and when the state goes to LVIS_SELECTED then there you go.

You could also try a handler for LVN_ITEMACTIVATE ... that looks like it would work

cmsdiginet,
It is unkind to grade with a B without posting any comment.  
If there was something about the response that you think is less than A-level material, then you should ask about that and give the Expert a chance to improve his response.
