Parameters
nID
Specifies the integer identifier of the control whose title is to be retrieved.
lpStr
Points to the buffer to receive the control’s title or text.
nMaxCount
Specifies the maximum length (in bytes) of the string to be copied to lpStr. If the string is longer than nMaxCount, it is truncated.
