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...
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! clodetta
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...
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:
Private intTrackingNumber AsIntegerPrivate intDateReceived AsIntegerPrivate strManufacturer AsStringPublicProperty TrackingNumber() AsIntegerGetReturn intTrackingNumber
intTrackingNumber = value
EndSetEndPropertyPublicProperty DateReceived() AsStringGet' TODO: Convert timestamp to formatted dateReturn intDateReceived
' TODO: Convert formatted date to timestamp
intDateReceived = value
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???
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?
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:
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?
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=188.8.131.52, 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.
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.
PrivateSub 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))
EndSubPrivateSub MsgBoxRet(ByVal sender AsObject, ByVal e As System.EventArgs)
If dr = DialogResult.Yes Then
I submit button Yes, but condition not works. I use WEB GUI form. Can you show me any type solution? Thank you
Hello guys. Working in C# when you collapse a function, only the functions signature remains visible while the rest of the function body changes into boxed ellipsis. The color of this ellipsis also changes accoring to the settings. Again, the color of the boxed ellipsis changes only. It looks something like this
int Function() ...
I want the same in VB.Net. Although the function signature remains visible but unlike CSharp, color of the whole function signature changes in VB.Net. At the very least, I don't feel comfortable with this.
I hope you got my problem. If so, is there a way to make this behavior similar to that of CSharp? Thanks for any suggestions.
This world is going to explode due to international politics, SOON.
