I try to use "Order by" to order a list of Dates beginning by the earliest in VB.Net.The variables and methods are:
-Dim SetupStart As DateTime
-Dim SetupTimeList As New List(Of Date)
if it doesn't make any sense I would be glad if some one could show me how to order this list ascending by the earlist date.

I am in ethiopia and we have 13 monthes. 12 of them with 30 days each and 13th month with 5 or 6 days. I want to sort my data by date using the bindingsource sort method. But to do that I need to set my date field a date data type. When i set the datatype to date, i can't enter some values like 13 for the month value and 30 for day value of 2nd month.
What I want is just to make my application accept 13 as a month and 30 as a day for all monthes, so that i can sort my data by date. Is it possible to do so by setting culture for my application or by some other means?

I'd want a text box that at design time the developer can set a datatype property so only a value matching that datatype can be entered at runtime (e.g. If we made the datatype property of a textbox an integer then the user could only enter numbers into that textbox)In additiion I need a further property to replace ".Text". .Text always holds the entered value as a string, I want the new property to contain what has been written into the textbox but as the datatype that has been selected at design time.

I am currently trying to develop a chat application which will work on a LAN, however encountering problems with with adding a user through the registration form, always getting the result :: "Datatype mismatch in criteria expression" I've tried checking and cross-checking the datatypes used in both the database(its a .mdb database,, created in Microsoft Access)this is the code i am using:
dim con as new oledbconnection
dim cmd as new oledbcommand
Public Sub UserReg()
[code]....
everything is done,, such as opening the connection and defining teh data reader, etc as you can see from teh code(which was derived from another question but i made edits to suit my use for it)I also have problems with checking wether a user is online. obviously i will be referring to the table to do that using something like
cmd = new oledbdatacommand("SELECT * FROM Users where isOnline = "Yes")
dim sdr as oledbdatareader = cmd.execute reader
whence it will show a list of all the currently "Online users" but i do not how how to quite refer to it?
I am using the following to get an array of a directory. I was recently told that I needed to process my files in date order.
Dim filelist() As String = IO.Directory.GetFileSystemEntries(CustomerDirectory, ConversionWildCard)
For Each filename As String In filelist
'do conversion here

how I can get the list of files in date order?
I don't think the, System.Collections.ObjectModel has any sort or order by capability.
I have a list of files and I'd like to sort by the file date.
Dim list AS System.Collections.ObjectModel.ReadOnlyCollection(Of String)
list = My.Computer.FileSystem.GetFiles("C:SearchFolder" _
, FileIO.SearchOption.SearchByTopLevelOnly _

This returns the last file, but based on file name and not date. I think I need to add .OrderBy(... just can't get that part.

Similarly I have a control datetimepicker in vb.net I have assigned format property as custom to the control and the CustomFormat property as HH:mm:ss tt so that it can just provide the time. I dont want the date to be in it.

If the other entry is set in the future on purpose, edit that entry to use the "Date Out of Order" option. Otherwise, use the "Date Out of Order" option for this entry instead." I haven't found an argument for the "Date Out of Order" option using the LJ.XMLRPC.postevent method.

The loop seems to start from the email in the middle of the list, cycles down to the end, then starts at the last email received and cycles down from there. When viewed in Outlook and sorted by latest email first and descending, the emails seems to be in order. This is my code:

View 9 RepliesI have a form that collects user parameters to print a report. There are two DateTimePickers to let the user select a date range for the report. The selection of a date range is optional so I set the From picker to a date before any data could be present. If the user wants to select a date range, the from field is set to a very old date so it takes a long time to get to any current dates. Whe I'd like to do is when the user drops down the picker, reset the date to today and let the user scroll from there.I tried the dropdown even in the picker, but the new date doesn't get set until the user has already selected a date. Any suggestions on how to get this type of UI behavior? Also any better suggestions to streamline the process?The main objective it to collect from and to dates from the user is they want to select them and collect wide ranging dates if the user doesn't enter any.
