View 4 RepliesClass - .NET - Automatically Initialize Extended Property Of Type Object?
Feb 15, 2012I am building a code behind page that has a public property (MyDTOItem) which is essentially a DTO object (dtDTOItem) Note: In my code the Get and Set are actually real code (I stripped it for the example).The problem I am having is in the Page_Load event. When I set the .Member1 property of the DTO object the Get code runs and not the Set and therefore the DTO ibject property .Member1 never gets assigned. I figured out that if I add code (MyDTOItem = New dtDTOItem) to the Page_Load event then it will set the value correctly. What I am trying to figure out is how to initialize the property object without having to do it explicitly. It has to be an extended property because I have custom Get and Set code.
Public Property MyDTOItem As dtDTOItem
Get
End Get
Set(value As dtDTOItem)

View 1 RepliesForms :: Object Property Change In Combobox?
Apr 7, 2010I am working on a project that uses lots of custom class objects.Before starting work on real project, I tested the object behaviour on a temporary project. And find that if i add the object to a list and combobox and then make any change to the object property then it reflects in list and combobox.But after using the same process in real project the change does not reflect. Why?Also, how can i update object property placed in the combobox.
for eg.
Class X has property id and name
created objX of type Class X and set id=1 and name='All'

Syntax To Change The Value Of A Cached Object Property?
Jun 6, 2010In an ASP.NET 3.5 VB web app, I successfully manage to cache an object containing several personal details such as name, address, etc. One of the items is CreditNum which I'd like to change in the cache on the fly. Is there a way to access this directly in the cache or do I have to destroy and rebuild the whole object just to change the value of objMemberDetails.CreditNum?The cache is set using:
Public Shared Sub CacheSet(ByVal key As String, ByVal value As Object)
Dim userID As String = HttpContext.Current.User.Identity.Name
HttpContext.Current.Cache(key & "_" & userID) = value
End Sub

VS 2005 : Put Existing Labels Into An Array (to Loop Through And Change .text Property)?
Jun 23, 2011I am writing an app to be a single button failover of a set of mirrored SQL servers. The app has to handle several other functions (enable/disable and start/stop of services, writing to local registry, copying files from server A to server B, initiating stored procedures, etc.)I have a collection of labels that indicate the status of 4 services on 2 servers, I wrote a function to check the services when passed the machine name, and the service name. Originally I just called the function 8 times (4 services, 2 machines) and populated the labels 'manually'. I have all of this within a timer so that the service status is refreshed every couple seconds. Id like to clean up the code to a single for/next loop that operates on 2 arrays (an array of service names, and an array of labels) such as:
'**Fetch_Status is the function that gets service status, it accepts 2 strings, machine name
'**and service name and returns status "running", "Stopped", as my_status
Dim Services() As String = {"Service1", "Service2", "Service3", etc.}
[code]....
The only reason I want the control array is to be able to use the .Text and .BackColor properties of the labels in the loop. If I make an array of strings with the label names it doesnt seem to pick that up.
Change A Value Of 1 Combo All Other Combos Change Automatically / Show Same Value As One That Was Changed
Aug 15, 2011I have 10 Comboboxes in a form. All these combo boxes have databound items which come from the same column in a table in the database (access 07) (Am designing a billing software, and these comboboxes show the items (10 lines of them).All these combos reside in one Groupbox.Now for the strange (scary/funny) part, whenever I change a value of 1 combo, all the other combos change automatically and show the same value as the one that was changed. (strange!).

Reflection - Find From A Property Info Object If That Property Has A Non Public (Private / Protected) Setter?
Aug 27, 2009I searched on the forum / Internet for the solution how a PropetryInfo object (of a Public property) can reveal if it has a Private Protected Setter ... it was all in vain .... all help I found was about how to "Set" value of a public property having a Private Setter.I would like to know if I have a PropertyInfo object of a public property, how would I know if its Setter is Non Public?
I tried, in a exception handling block, where I did a GetValue of the PropertyInfo object and then called SetValue by setting the same value back... but to my surprise it worked well and didn error out.

If Me.Child.Equals(value) Then ...
Both gives an error. What should I do to pass these lines? Also in C# it would look like this:
if(this.Child != null) ...
if (this.Child != value) ...
But this time it doesn't give an error.
