Subj : Slider Problems

Hi!
I asked this question in 1996 in OS2.PROG.GER, got no answer and ran into it
this evening once again: what am I doing wrong with my slider?
There is a slider inside a dialog, the dialog was created via IBM's Dialog
Editor (see progress.dlg). The Dialog Editor isn't able to define ticks or
scale texts. So I'm doing it by hand (see drverify.cpp).
None of the calls fail but the result is ugly:
0 20 40 60 80 10
| | | | | |
xxxxxxxxxxxxxxxxxxxxxxxxxx
The problem is that the "100" is cut after the first zero. Questions are: why
and how do I avoid this? Answers?
==================<drverify.cpp>============================
{
WinSendDlgItemMsg(hwndDlg, SL_PROGPERCENT,
SLM_SETTICKSIZE, MPFROM2SHORT(SMA_SETALLTICKS,6), NULL);
for( unsigned i = 0; i < 6; ++i )
{
char str[8];
sprintf(str, "%u", i * 20);
WinSendDlgItemMsg(hwndDlg, SL_PROGPERCENT,
SLM_SETSCALETEXT, MPFROMSHORT(i),
MPFROMP(str));
}
}
