Hi!<br />
<br />
The main problem is, that fonts can be different in CDC (through the pCDC pointer) and in the listbox.<br />
Try to synchronize fonts and the problem will be solved.<br />
Or You can try:<br />
CListBox::SetColumnWidth(i<wbr />nt cxWidth );<br />
Also, maybe you have problem with scrollbar himself. Try to set scroll range. Use the CListBox's<br />
void SetScrollRange( int nBar, int nMinPos, int nMaxPos, BOOL bRedraw = TRUE );<br />
function where the nBar is:<br />
SB_HORZ &nbsp; <br />
<br />
CF

Hi!<br />
Try sync DC ascyberfranc said and also try DrawText with DT_CALCRECT param

If you try the code, you'll find it.<br />
<br />
extentName=pCDC-&gt;GetTextEx<wbr />tent(LongN<wbr />ame,strlen<wbr />(LongName)<wbr />);<br />
if(strlen(LongName)&gt;30){<br />
&nbsp; m_listCtrl.SetHorizontalEx<wbr />tent(exten<wbr />tName.cx);<wbr /><br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br />
Note:30 is the characters listbox can hold. <br />
<br />
The more long string is, the more obvious inaccuracy is.<br />
<br />
Any idea? &nbsp;

If you try the code, you'll find it.

extentName=pCDC->GetTextExtent(LongName,strlen(LongName));
if(strlen(LongName)>30){
  m_listCtrl.SetHorizontalExtent(extentName.cx);
	}
Note:30 is the characters listbox can hold. 

The more long string is, the more obvious inaccuracy is.

Any idea?  

GetTextExtent( ) returns inaccurate pixels
