Are you sure that creating/destroying the brush each time is that expensive? Try it and see how the program performs.

use SetWindowHookEx as follows

SetWindowsHookEx( WH_MOUSE, MouseProc,0,0);

u should write a function write a function(here "MouseProc") with prototype

LRESULT CALLBACK MouseProc( int nCode,
WPARAM wParam,
LPARAM lParam
);

Now u will get all the mouse messages in the function "MouseProc".

The above hook only works inside ur application scope. For u to make the hook globel u should have to write the "MouseProc" in a dll. and pass the instance(obtained from LoadLibrary) as the third parameter to the SetWindowsHookEx function.

Hi Naveen,

Thanks..
As us said i am looking for a global mouse hook.
are there any rules for the dll like it should be a com outproc server or
is it enough to be ordinaly dll.

thanks and regards,
Ram

How to do complex window UI?

derek73-Mar-06 0:58

if use dialog, it is easy,because vc supply a dialog editor, you can design your UI very intuitionistic.

but for a complex UI for example vc6(not complex as that ,just a example)

how to do? Must I calculate the coordinate of control(position ,size etc...) by hard code?

i don't want to increase the height of the header control( since i am not owner drawing it), But i want to change the all items height to a number. Actually what happened is when i increased the font size, the font desen't fit in the cell and its getting clipped. iwant to avoid that.

Thanks

In your CListCtrl derived class, overload the MeasureItem handler. Note that we don't call the base class MeasureItem as this will change the item height back to the default.

<br />
void CCustomListCtrl::MeasureItem(LPMEASUREITEMSTRUCT lpMeasureItemStruct)<br />
{<br />
    if (lpMeasureItemStruct->CtlType == ODT_LISTVIEW)<br />
    {<br />
         lpMeasureItemStruct->itemHeight = 20;<br />
    }<br />
//Don't call the base class MeasureItem as the base handler will change the itemHeight back to the default<br />
//Height!<br />
//	CListCtrl::MeasureItem(lpMeasureItemStruct);<br />
}<br />
<br />
