Ok. I did not look further to where a was used. But still
consider it bad programming style. If one would add a Showmessage(a);
or a logit(a); then there could be trouble.

That still is not nice. As length depends now on cFileName and not directly
on the contents of a.

     char a[200] = {0};
     strncpy(a, cFileName.c_str(), 199);

     DrawTextEx(lb->Canvas->Handle, a, strlen(a), &r,
	DT_MODIFYSTRING | DT_PATH_ELLIPSIS, NULL);

Hans.
