I ran across a nearly identical problem with BC++ 2.0. I was attempting
to use SetDlgItemText() with the second parameter a literal string, e.g.

SetDlgItemText(hwnd, "Something");

I kept getting either a blank control, a %d, or a '- [%s]' in the item.

My solution? I CHANGED THE FILE EXTENSION FROM .CPP to .C, AND NOW THE
PROGRAM WORKS!?!?!?!?!?!?!

Since I'm relatively new to C++, I thought it might be attributable to
some subtle difference in the languages, and temporarily dismissed it.
Seeing your message, however, makes me start to wonder...

Some more tidbits of info on this problem: calls such as

SetDlgItemText(hwnd, strupr(ltoa(0L, szBuffer, 16)));

where szBuffer is declared as

char szBuffer[20];

work fine, even in .CPP mode. If I try to send it a literal string,
or if I try to send it szBuffer directly after putting some characters
into it, SetDlgItemText pukes.

Anyone else stumble across this one? What's the deal??
