Design - Pass User Details Between Objects?
Aug 16, 2010
I'm redesigning an old VB6 application into VB.net and there is one thing I'm not sure on the best way to do. In the VB6 application whenever we created a new instance of a component, we would pass in the user details (user name and the like) so we new who was performing the tasks. However, no that I'm redesigning I've created some nice class designs, but I'm having to add in user details into every class and it just looks wrong.
Is there a VB.net way of doing this so my classes can just have class specific details? Some way so that if my classes need to know who is performing a task, they can get the information themselves, rather than having it passed in whenever the objects are created?

I'm trying to get a details view in ASP.NET to display the details of the logged-in user only. I have been told to use:
select * from STAFF where USERNAME = user.identity.name
I thought this was too simple to be true and I was correct as it shows no data when I attempt to run.

I have created a PictureBox array to hold 104 playing cards that are all visible at the same time.I did this with this line in the declarations:Shared Card(104) As PictureBox
And with these lines in the Form_Load module:
For I% = 1 To 104
Card(I%) = New PictureBox
Card(I%).Name = String.Format("Card{0}", I%.ToString)
Card(I%).Size = New Size(71, 96)
[Code]...
I have been successful in creating the array, positioning each and entering the images for all 104 PictureBoxes, but now I want to add code for the event "MouseDown.I copied the code for this event from my VB3 program and VB10 automatically updated the list of parameters, but nothing has linked the objects (Card) to the code.
I have tried to append "Handles Card.MouseDown" as well as several variations with brackets to indicate that it is an array.Auto-complete doesn't include "Card" as an option, and of course, since the array was never an object added to the form design, I can't create the empty module from there.

I have a scenario at hand which has some design discussion going on. To break it down in simple words, think about a hierarchy as such Company -----> Customer ------> Orders (ignore the details of how the orders have products etc) if I was to expose an API to work with this, what would be a better design.
a)
Dim comp As New Company
comp.GetInfo(123)
Dim cust As New Customer
cust.Name= "CustomerName"
comp.Add( cust)
b)
Dim custhand As Customerhandler
Dim cust As New Customer
cust.Name= "CustomerName"
custhand.AddCustomer(cust,123) ''123 is CompanyID

I have an object of type Dictionary(Of Int16, Polygon) and which contains sometimes up to 15 or so Polygons that i am creating bitmap files with the Polygon. This can take like 20 seconds sometimes so i was trying to pass the full Dictionary to background worker as an argument but i get an issue when trying to access each individual Polygon inside of the Dictionary because the Polygons still belong to the UI thread. How can I access the Polygons inside the Dictionary with the backgroundworker?
Dim worker As New BackgroundWorker
AddHandler worker.DoWork, AddressOf MeasurePolygons
AddHandler worker.RunWorkerCompleted, AddressOf WorkerCompleted
worker.RunWorkerAsync(PolygonCollection)
that is how im calling the thread. PolygonCollection is the Dictionary(Of Int16, Polygon) that contains all the polygons that i will be creating a bitmap file out of.

I am finding that this may not be possible, but am trying to see if anybody has a solution.
I have four classes, two are core classes and two are those core classes extended[code]...
This fails because es is of type, extSecurity and the base class expects a type of coreSecurity. I've not found anyway to cast this to allow for me to override this base class in C#. In VB it works just fine.

we have a script which we use here to output a list of all the groups a user belongs to (for records before deletion) and it works fine for the first domain, but any sub domain are not searched. (due to "LDAP://rootDSE" I think)here is our current script
On Error Resume Next
Const ForWriting = 2
UserName = InputBox("Enter Username","Enter Username")
[code]....
I want the script to search through all domains and sub-domains it can find until it finds the user, or runs out of domains to search. Once found, it then dumps the groups to a file (like it does now)

I have created a COM Object via VB .NET and exposed some functions that I wish to call in Excel using VBA. I am currently trying to pass an array of objects as a result to VBA but Excel is complaining the following:
'Function or interface marked as restricted, or the function uses an automation type not supported in Visual Basic.'
I have looked around on the internet and have seen similar issues but not to one I am trying to do.My VB .NET function, which I wish to call in Excel is declared as follows:
Public Function CallArray(ByVal serviceName As String, _
ByVal effectiveDate As String,
ByVal serviceParams() As System.Object,
ByRef ArrayRes() As System.Object) As System.Boolean
VBA is complaining about the System.Objects my question is how the heck are you supposed to pass and return arrays from .NET to VBA. Also the data that will be in the ArrayRes() is mixed type, its not just strings etc, its an array of arrays that can contain strings, integers doubles etc.I chose VB .NET because I assumed it would be possible to map to VBA easier.if System. Object and Arrays in VB .NET is not the way, ie maybe theres another way via collections or lists, then Im open to that. I just need to get this data into VBA.Also I could move over to C# if needs be.

What is the best way to pass objects between threads? I would like to create a new thread that creates a new object : Dim myobject as newobject = new newoject Then in my main thread, I would like to use myobject. Ideally I would like to just assign to a global variable but I don't think that is possible. I think I may have to use some form of delegate function (but I think the child thread would need to complete to use a callback). The new thread will not actually end before I need the object reference in the main thread. How should I go about this?

I am trying to set up a new internal system for my client currently, they insisted on integrating the login with AD, which makes sense, and i have managed that with no problem. However what i also want to do, after authentication, is to store some user details / attributes as session variables. I have the following code to aithenticate the user:
'this function authenticates against AD - very simple and works nicely.
Function AuthenticateUser(path As String, user As String, pass As String) As Boolean
Dim de As New DirectoryEntry(path, user, pass, AuthenticationTypes.Secure)
[code]....
which works nicely, and once the function returns me a True, i set Session("LoggedIn") as True.what i need to do is (hopefully within the above function) save the user's name, and 2 other custom atributes from within the user's AD profile.How would i access those (hypothetically)

I've see this application which can dig out our User Name from somewhere and asks our password. To be on the safe side, I typed my wrong password and it could cross-check that it was a wrong password and it asked me to type the right password. My question is:
How do you dig out logged in user's User Name?
How do you verify if a password given matches with the one really used to log into windows?
How do we auto-login by providing these verified details you say at a specific time by regularly checking the time using a timer?

I am new to vb.net and am trying to design a routine that will allow the user to search for a record and return the results in a datagrid. Then double click on a row within the datagrid to view a more detailed form. I have been able to build the search form but am having problems with the double click event.I found a sample application on the Microsoft web site which is doing this on a smaller scale. The sample is built on the Northwind sql database and searches the customer table when you double click a row in the datagrid the following Microsoft code runs and opens a detailed form.

I am developing an application in which I would like to let the users design some forms and decide the fields that are in the form.An example is better than a poor explanation, so let me put the example of Microsoft CRM in which you as end user can define a form, the fields in that form, or customize existing forms by adding or removing fields.

This is a related to my last post, but not enough to make sense as a tag on question.I have a collection(of myClass) that is exposed as a public property in a user control.When I add an item to the collection in code I would make the call collection.add(new myClass) and of course the constructor for myClass is called.When I add items to the collection via the design time menu the constructor for myClass is not called.... of it it is called, I can't see any evidence of it.

I'm trying to make a simple User control that houses one collection of a class that I've made. After building the control All works as planned and then randomly when I try to go to the design time interface for the form I placed the control on I get an error page with the following:
To Prevent Possible data loss before loading the designer, the following errors must be resolved:(ignore and continue: which about half the time works and the control shows up and the other part of the time all of the controls on the page are missing)
The one error is the following:Object of type'System.Collections.Generic.List'1[StaticGraphPlot.clsStaticCurveData]' cannot be converted to type System.Collections.Generic.List'1[StaticGraphPlot.clsStaticCurveData]'.

I have created a user control that mimics what a label does. I realize I could have inherited the label control, but I am working on understanding the process. I wish to add items to the control. normally (in the code of my project) would do:
Form1.Label1.Controls.Add(mylabel)
After creating mylabel in the code of course.
