new CString(L&quot;Delete Me&quot;) &lt;==== causes memory leak of the CString object. <br />
It's better to use LPCTSTR pointer OR just at destruction delete the CString object..no need to ue new operator.<br />

can you explain how this cause a memory leak? &nbsp;how to use LPCTSTR pointer in this case?<br />

what happens if you just send <br />
AfxGetMainWnd()-&gt;SendMessa<wbr />ge(WM_MY_M<wbr />ESSAGE, 0 ,CString(L&quot;Delete Me&quot;) ); &lt;==<br />

what happens if you just send
AfxGetMainWnd()->SendMessage(WM_MY_MESSAGE, 0 ,CString(L"Delete Me") ); <==

the reason I use new because a pointer to CString can be casted to LPARAM. &nbsp;the above usage of CString on the stack will give an error: &nbsp;cannot convert from CString to LPARAM

&gt;&gt; how to use LPCTSTR pointer in this case?<br />
ie.<br />
<br />
SendMessage(WM_MY_MESSAGE,<wbr /> 0 ,(LPARAM) (LPCTSTR)&quot;Delete Me&quot;) &lt;== now handle this in your function as LPCTSTR<br />

AfxGetMainWnd()-&gt;SendMessa<wbr />ge(WM_MY_M<wbr />ESSAGE, 0 , new CString(L&quot;Delete Me&quot;) );<br />

I am wondering if this creates a memory leak even doing a delete.<br />
<br />
LRESULT ::OnMyMessage(WPARAM wp, LPARAM lp)<br />
