I can't change size of my rows in this CListCtrl:
class CResolutionListCtrl : public CMFCListCtrl

That's a method that I realize in class, according different tutorials:

afx_msg void MeasureItem ( LPMEASUREITEMSTRUCT lpMeasureItemStruct );
virtual void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct);
afx_msg void OnMeasureItem(int nIDCtl, LPMEASUREITEMSTRUCT lpMeasureItemStruct);
afx_msg void OnCustomDraw(NMHDR* pNMHDR, LRESULT* pResult);


I can't change height in any ways:
even with this very popular tutorial
Changing Row Height in an owner drawn Control[^]

And actually my OnMeasureItem and MeasureItem never call. I've already tried change different flags like:
owner Draw etc.
Please provide some simple example to change size of cell, because everything that I found is really a lot of coding or doesn't work.
Thank you a lot

If your OnMearureItem is not called at least once that is an indication that the control is not an owner-draw control. You might want to use Spy++ to check that.

Perhaps the following snippet from the MSDN documentation will help you find the reason for that:

OnMeasureItem will be called only if the control's class is created at run time, or it is created with the LBS_OWNERDRAWVARIABLE or CBS_OWNERDRAWVARIABLE style. If the control is created by the dialog editor, OnMeasureItem will not be called. This is because the WM_MEASUREITEM message is sent early in the creation process of the control. If you subclass by using DDX_Control, SubclassDlgItem, or SubclassWindow, the subclassing usually occurs after the creation process. Therefore, there is no way to handle the WM_MEASUREITEM message in the control's OnChildNotify function, which is the mechanism MFC uses to implement ON_WM_MEASUREITEM_REFLECT.

Hope that solves your problem.
