I want to get number of days in a month. Here is my requirement if I am selecting month name in a combobox then I am displaying days in another combobox.
Example :
If I am selecting JAN in one combobox then 1 to 31 numbered bind to another combobox.
If I am seleing FEB in a ombobox 1 to 28 numbers added to the combobox.
I want to do this in vb.net (windows application).
I am supost to code a program for my homework using an one-dimensional array.in the program you enter the number of the moth and it gives you how many days are in that month. and I'm just kind of lost?

View 1 RepliesHow do I calculate the difference between two dates to display as a number in days?I have 2 text boxes (txtHStart_Date & txtHEnd_Date) I have used an Ajax Calendar Extender to enter the dates in each of these text boxes.I would like to get the difference between these two dates to show in a seperate text box (txtNoOfDays)
I've seen the timespan function but can seem to get this to work. I'm not to sure how to declare the text boxes as the dates I would the calculation to be made from
Code:
Dim D1 As Date
Dim D2 As Date
Dim ts As New TimeSpan
D1 = txtHStart_Date.Text
D2 = txtHEnd_Date.Text
ts = D2 - D1
But I know this isn't right. I also don't know how to get it to display in the 3rd TextBox.
I have a program for class that requires you to have the user enter the number of days they wish to save for and then the program takes 1 penny and doubles every day for the amount of days the person enters. I was able to get this to work in Raptor but not VB.
'Description: Taking one penny and doubling it over the number of days the user enters.
Dim decPennies As Decimal = 0
Dim intTotaldays As Integer = 0
