I have the following powershell script which loads a custom .NET DLL this contains the ScriptResult class, it is intern executed from a VB.NET app.
Add-Type -Path $myLibPath
$result = New-Object TheLibrary.ScriptResult
[code].....
I wonder if it is possible to write and capture errors when running a script to PowerShell.In my case I am using the following code:[code]' add an extra command to transform the script output objects into nicely formatted strings' remove this line to get the actual objects that the script returns, for example, see the script "Get-Process" returns a collection.[code]
View 4 RepliesI need to get the host out of the Request object. Which property should I use and why?
From MSDN:Uri.DnsSafeHost Property A String that contains the unescaped host part of the URI that is suitable for DNS resolution; or the original unescaped host string, if it is already suitable for resolution.
vs
Uri.Host Property A String that contains the host name. This is usually the DNS host name or IP address of the server.
My testing has been with the ASP.NET Development Server. Both of these always return localhost. Even when I put in 127.0.0.1, both return localhost.Reading on, the DnsSafeHost property will handle IPv6 addresses, as well as Unicode to ASCII conversion if needed. It can also account for IRI and IDN. Even though I currently don't care about these things, should I just use the DnsSafeHost property to be safe?
I'm working up a system where I plan on using RealProxy objects to enable intercepting method calls against a set of objects, handling the call, and then returning appropriate results. This works just find for simple return types like strings or ints, but I can't seem to return objects from the RealProxy.Invoke method. Everything works. I get no errors, but the returned value is always NOTHING, instead of an object.
I've worked up the smallest sample code I could, and have included it below. Essentially, just call RPtest and single step through. The code creates a simple object, RPTestA, with a string field and an object valued field It then retrieves the string

I have an application that creates desktop shortcuts. To do this I have to reference the Windows Script Host Object Model. When I add it as a reference, it always creates the DLL, Interop.IWshRuntimeLibrary.dll, in the objx86Debug directory, then references itself to it, rather than looking at wshom.ocx. Even if I add reference wshom.ocx it reverts to saving the file in the objx86Debug directory. The problem is if I move my application to another computer without that DLL being present, the program fails to run.

Is there a way to make an interface serializable, or am I going to have to convert each of my objects into a concrete class implementing the interface, and then return that class?
I have created a custom user control (JCUserControl), and I am using it in the Main Window. And my Main Window has no codebehind. I have this in the JCUserControl codebehind:
Private Sub ImmediateRadioButton_Checked(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles ImmediateRadioButton.Checked
SomeTextBox.IsEnabled = False
End Sub
When I run it, it fails with the NullReferenceException. If I comment out the SomeTextBox.IsEnabled = false, it runs without any problems.
Edit: Found out that I could just check if the radio buttons are loaded before doing whatever I want to do.
Private Sub ImmediateRadioButton_Checked(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles ImmediateRadioButton.Checked
If ImmediateRadioButton.IsLoaded Then
SomeTextBox.IsEnabled = False
End If
End Sub

View 4 RepliesI'm making a class that reads a file and processes data in it, but I need some error handling. I'm giving it a constructor that takes a file location and processes that file. How can I make it so the constructor tells the program whether it found the file or not? Optimistically the program that calls this class would check for that first, but since I'm not going to be the only one that uses this class I'd like to know how to secure such a thing. It's probably bad practice to do this within the class, but I'd like to be sure it's as portable as possible.

View 2 RepliesSo I have an application that uses a webservice, On the UI side the user picks a table which sends a request across the web to my webservice to return the fields of this table. So after this request is accomplished I have, on the webservice side a series of Name,Type Pairs that I need to serialize and send back to my client. I could use a List(of String()) to send the values back but I want to use a List(of Custom_Class) instead because later I have to do this on a much larger scale and I want to learn on this simpler version.

After reading all the examples for list of T exists and Find and find first, none show how to handle multi-property objects. Below is bare bones example maybe someone could flesh out to show how this should be done.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim DatePriceList As New List(Of DateAndPrice)
DatePriceList.Add(New DateAndPrice(Date.Parse("1/1/2000"), 10.12))
DatePriceList.Add(New DateAndPrice(Date.Parse("1/2/2000"), 11.12))

I'm learning .NET and I've got a question about user controls. I'm using VS 2010.. I've created an user control, which contains a textbox (code), a button and a label. When you fill in the textbox, the system searches of the codes exists, if so, the description is showed in the label, else it's cleared. When you click the button, a form opens with a datagrid where you can select a code. When you select a code in the datagrid, the code textbox should be filled in with the selected code. How do you return the selected value to the custom control? I've created a public property in the custom control, but i can't access it.

similar to how 'toString' works, except it would return a button object instead of a string. (im not sure how toString works in vb.net. in java it is automatically called when you call the new class, so newclass and newclass.toString(); return the same) [code]...

The basic idea is simple, but once I find the control I want, say five 'layers' in, the control is returned only one level.
I know I can do something cheesy like having a private variable and assigning the control to that down in the rabbit hole, but I figure there must be a more official method of doing this.[code]...
