Hi Luckie,
Robert dürfte Recht haben. In der D6-Hilfe (
Win32 SDK) steht:
DT_EXPANDTABS
Expands tab characters. The default number of characters per tab is eight.
DT_TABSTOP
Sets tab stops. Bits 15-8 (high-order byte of the low-order word) of the uFormat parameter specify the number of characters for each tab. The default number of characters per tab is eight.
