Hi Clodetta,
The MouseDown[^]-Event might be worth a try.
|
|
|
|
|
hello, Marco.
thank you for your suggestion!!!
i´ll give that a try...
i´m developing for surface, so I thought that this event isn´t what I want...
i´ll report my findings...
until then,
clodetta
edit:
that is winforms-related, I guess...
|

Hmm... Can you just look for a similar event in the XAML-control?
Another solution could be that you have a second variable where your current index is stored... You would have to update this variable manually and it would end up kinda unclean but this could be the emergency-solution.

Hi, Marco.
sorry for replying late....
first of all: thank you for your help.
I´ve found several events (ItemClick, Tapped etc) but none of them seem to suit.
your second suggestion leads me back to my initial question:
where to save the old index...?
I wonder what the softie´s intention was when they decided not to implement a SelectedIndex_Changing in addition to SelectedIndex_Changed.
that would solve the issue perfectly...

Create a new control which inherits from the listview control. In the code-behind you can add the logic to handle the case and are maybe able to fire your own, custom selected index changing event...
cheers,

That´s also a good idea, but I have already solved the problem, I think, I´ll leave it at that.
it now works the way it should, that´s sufficient for me!
Thank you again for your help!
kind regards!

ok, finally I got it...
it´s more like right through the chest into the eye, but now it works...
a healthy mixture of ListView.SelectedIndex_Change and Grid.GotFocus did the trick for me; now I can save the old AND the new index....
thanks to marco for his suggestions!
post scriptum:
I can´t find the checkbox for marking my thread as solved...
I guess i´m blind...

Hi All,
I have two scheduled tasks running, I want to replace the compiled code for those scheduled tasks without deleting them. How can I do that step by step.
Any help, like link or suggestion over here helps. Thanks in advance.
Thanks & Regards,

You mean replacing the files alone without affecting the schedule task in windows schedule task manager?
|
|
|
|
|
Just replace the .EXE file the task is going to use?? Just keep in mind the filename cannot change.

Greetings all - I haven't posted here in ages I am entirely new to .Net having been working in it for a week at most so please go easy and be detailed as possible
I have the following PONO:
Public Class WorkOrderEntity
Private intTrackingNumber As Integer
Private intDateReceived As Integer
Private strManufacturer As String
Public Property TrackingNumber() As Integer
Get
Return intTrackingNumber
End Get
Set(value As Integer)
intTrackingNumber = value
End Set
End Property
Public Property DateReceived() As String
Get
Return intDateReceived
End Get
Set(value As String)
intDateReceived = value
End Set
End Property
End Class
The issue I am faced with is how to store date/time as a timestamp (integer) but provide public properties which format/convert accordingly.
I suppose I could provide a an additional getter()/setter() but ideally I wonder if EF has a way of circumventing this "convention"?
Additionally - I am also curious as to whether it's possible to map properties to columns which are not labeled correctly?
Basically if I were working in a existing database (EF automatically builds my PONO with properties named after table fields) I wish to name the fields something more meaningful; some fields for example might be awkward abbreviations but in the object model I want something more English friendly?
I seem to recall being able to do this with Hibernate in java (actually it's PHP port) but never the less does EF support such a feature? Seems obvious that this would be useful in day to day development???
Any ideas?
Regards,
Alex

When you say "timestamp", what do you mean? If it's the SQL timestamp type[^], this has nothing to do with dates:
a data type that exposes automatically generated, unique binary numbers within a database.
The timestamp data type is just an incrementing number and does not preserve a date or a time.
You can map a property to a column with a different name using either the Column attribute[^] or the fluent API[^].

I just found some articles that explain how to change the mapping for tables so I imagine columns are just around the corner.
When I say timestamp I mean a unix timestamp which can easily be converted to date AND/OR time - not sure what MSDN is getting at?!?
In the database I wish to store the date "10/10/2013" as 1381381200 but convert to a human friendly date within the PONO.
My entity objects are high level abstractions but I still prefer to store the time in a numeric format - how does EF solve/address this type mis-match? This is/was the impetus behind OR/M frameworks ain't it?

Alex

Ah, OK - "timestamp" in SQL is something totally different.
I don't think there's any built-in way to perform this sort of conversion in the mapping layer. The simplest approach is probably to add a calculated property for the date, decorated with the NotMapped attribute:
Public Class WorkOrderEntity
Private Shared ReadOnly Epoch As New DateTimeOffset(1970, 1, 1, 0, 0, 0, TimeSpan.Zero)
<Column("DateReceived")> _
Public Property DateReceivedTimestamp() As Integer
<NotMapped> _
Public Property DateReceived() As DateTimeOffset
Get
Return Epoch.AddSeconds(DateReceivedTimestamp)
End Get
Set
DateReceivedTimestamp = CInt(Math.Floor((value - Epoch).TotalSeconds))
End Set
End Property
End Class
I'd be inclined to use DateTimeOffset for the property rather than a string; formatting the date should be a UI concern.

EF will see a .NET type of DateTime in your POCO and use the native DateTime datatype specified by the underlying data provider. It will not convert a DateTime to a "serial number" as you want because the serial number can be based on any arbitrary epoch. For example, UNIX uses 1/1/1970 00:00:00AM whereas .NET uses 1/1/0001 00:00:00AM. So, to each system, the datetime serial number will mean something different.
Why even do this?? Why not just let the underlying database handle the storage and return the correct datetime without your code having to worry about conversion?

Hi,
Please, I really need a help.
Everytime I try to launch every Kinect application, VS 2010 indicates me that there is a problem with the Runtime in Microsoft.Research.Kinect.
Everytime, I get this :
"Impossible de charger le fichier ou l'assembly 'INuiInstanceHelper, Version=1.0.0.10, Culture=neutral, PublicKeyToken=31bf3856ad364e35' ou une de ses dépendances. Le fichier spécifié est introuvable."
Please, can you tell me what's wrong and what I have to do.
Thank you very much.

It means that it cannot find the assembly named in the message, or some other assembly that INuiInstanceHelper depends on. Check that you have the correct version of .NET installed and any third party products that are needed.

Thank you for the answer,
Yet, I imported the "Microsoft.Research.Kinect" in the Referencies Forlder and declared it in the code behind...
Imports Microsoft.Research.Kinect.Nui
Imports Microsoft.Research.Kinect.Audio
Private nui As New Runtime
Even if I try to lauch downloaded projects containing the Microsoft.Research.Kinect Library, it does the same thing.

Please explain how memory managment is done in .Net Framework in detail
|
|
|
|

Since it's already been done thousands of times all over the web, you can go read those articles instead of expecting one of us to write it up again for the 2,440,001st time.
Read these[^]
A simple Google for ".net memory management" would have told you everything you wanted to know.

..that might take a day
Start here[^] and read all the links that the documentation points to.

Why is not TRUE this case:
Private Sub EliminaN_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles EliminaN.Click
dr = MessageBox.Show("Do you want Delete notification?", "Delete Notification", MessageBoxButtons.YesNo, New System.EventHandler(AddressOf MsgBoxRet))
End Sub
Private Sub MsgBoxRet(ByVal sender As Object, ByVal e As System.EventArgs)
If dr = DialogResult.Yes Then
Delete()
End If
End Sub
I submit button Yes, but condition not works.
I use WEB GUI form. Can you show me any type solution? Thank you
