The following piece of code does not work on DMC:
(It works fine with other compilers - BCC 5.02, LCC-win32)

!!!Now full source is included!!! (see attachment)
//============================================
long tmp_gwl;

/*getting current listview style*/
/*tmp_gwl=0x50000100=WS_VISIBLE | WS_CHILD | LVS_ICON | LVS_AUTOARRANGE*/
tmp_gwl=GetWindowLong(hlistview, GWL_STYLE);

tmp_gwl=tmp_gwl & ~LVS_TYPEMASK;

/*trying to set new style*/
/*tmp_gwl=0x50000103=WS_VISIBLE | WS_CHILD | LVS_LIST | LVS_AUTOARRANGE*/
tmp_gwl=tmp_gwl | LVS_LIST;
SetWindowLong(hlistview, GWL_STYLE, tmp_gwl);
//============================================
If I use GetWindowLong after these lines, it returns
the style I was trying to set,
but visually there will be no changes!

you can do all of this in Resource Studio very easily.

Phill.
