How about this?

DateAdd(DateInterval.Day, -1, Today.Date).ToLongDateString

What are you bone lazy our just thick Mad | :mad:

. You have been given some samples, hints and if you read some of the other answers here there is plenty of examples of date manipulation.

If you cannot work out how to get the information you need with start you have been given then give up being a programmer - you are not going to make it.

Don't call Now repeatedly. If you are unlucky (i.e. use it often enough) it will give you the wrong result, as the value may change from one call to the next.

To get the last day of the month you just add one month and subtract one day.

Dim n As DateTime = DateTime.Today
Dim first As New DateTime(n.Year, n.Month, 1)
Dim last As DateTime = first.AddMonths(1).AddDays(-1)

Despite everything, the person most likely to be fooling you next is yourself.

Bloody hell, I've been working with the datetime object for ages and didn't know about the add***** methods. This is the other reason I lurk here.

Thanks Guffa have 5

thanks Guffa. mycroft holmes that been lashin has ofcourse learn from my 'lazi'. i did not phrase the probem well. i need to be able to put all folders created by my application at the end of a month in a single folder( that is first day of july,sum for june). i have been able to get the logic like is

'Dim fd As New DateTime(DateTime.Now.Year, DateTime.Now.Month, 1)
'lastday = DateAdd(DateInterval.Month, 0, fd).ToLongDateString

'If Today.ToLongDateString.Equals(lastday) Then
the move here

endif
thanks once more for your advice

So, what you really want is that at the beginning of a new month, you want to move all the folders of the previous month?

Something like:

Dim today As DateTime = DateTime.Today
If today.Day = 1 Then
   Dim t As DateTime = today.AddMonths(-1)
   While t < today
      Dim folder As String = t.ToLongDateString
      If Directory.Exists(folder)
         ' move it
      End If
      t = t.AddDays(1)
   End While
End If

Despite everything, the person most likely to be fooling you next is yourself.

Hi,

I dont see any value property for button. When I convert VB6 application to VB.net, the code as follows

VB 6.0
Public Property Get VarArray(ByVal ctrl As Control) As String

VarArray = ctrl.Value

End Property

After converting to VB.NET
Public ReadOnly Property VarArray(ByVal ctrl As System.Windows.Forms.Control) As String
Get

'UPGRADE_WARNING: Couldn't resolve default property of object ctrl.Value. Click for more: 'ms-help://MS.VSCC.v80/dv_commoner/local/redirect.htm?keyword="6A50421D-15FE-4896-8A1B-2EC21E9037B2"'
VarArray = ctrl.Value

End Get
End Property

Here VB.NET code is giving compilation error "Value is not member of 'System.Windows.Forms.Control'"

Please let me know how to do this.

Thanks in Advance,

AR Reddy

You could consider going through the trouble of inheriting System.Windows.Forms.Button to create your own button control that has a Value property, but that process, although not particularly difficult, may still not be necessary. Maybe you can simply manipulate the button's Tag property in .Net to emulate how you were using the Value property?

A couple things:

First, the property Value on a CommandButton in VB6 is a Boolean - not a string.

Secondly, In all of VB6's infinite wisdom, doing Call Command1_Click() has the same effect of setting Command1.Value=True in code. So, the only time VarArray in your VB6 code above would be true is when Command1_Click() is called. Sigh | :sigh:

If you are using RadioButtons or CheckBoxes, Value was replaced by Checked.

Add a month to the 1st day of this month.

Looking at your questions, I'd suggest getting the big reference manual called Google working for you - or give up programming as you don't seem to have any concept of researching 'problems'

It was meant to be helpful.

If you are serious about becoming a programmer you need to be able to research problems yourself, rather than just posting questions to forums. Your questions about date manipulation are very basic and easily answered by looking at the Visual Studio help, or just typing into Google. What will you do if you have a production problem in the middle of the night, when an answer is needed asap? Post a question here and wait for possibly several hours for an answer or use BOL and Google and think for yourself?

As an ex Development Manager, prior to a face to face interview I would ask what forums a candidate was a member of, and their user name. I then checked on their postings. If I saw loads of simple questions and no serous replies I would not waste my time interviewing them.

That was my point, so your sarcasm was not appreciated. Hmmm | :|

BTW, your profile says you are in the USA so why ask
