Note that I needed to use lngdays-1 to add 1 day less than a month (ie 31-Jan-2011), else you would have had 01-Feb-2011 as the result

Dim strDate As String
Dim lngdays As Long
strDate = "01/2011"
lngdays = DateDiff("d", strDate, DateAdd("m", 1, strDate))
MsgBox Format(DateAdd("d", lngdays - 1, strDate), "ffffdd (dd/mm/yyyy)")

old

 Dim lngdays As Long
 lngdays = DateDiff("d", "01/2011", DateAdd("m", 1, "01/2011"))
 MsgBox Format(DateSerial(2011, 1, lngdays), "ffffdd (dd/mm/yyyy)")

Answer 2

Use format function like this. Here i used Now but you can pass any date and format return string of dayname

Format(Now, "ffffdd")

Answer 3

You can use DateSerial Function in VB6 to convert a string or integer variable to Date Variable

Dim d As String
Dim datevar As Date
d = "31"
datevar = DateSerial(2011,1, Val(d))   
MsgBox Format(datevar,"DDDD dd/MMM/yyyy")
