Pull The "modifytimestamp" And "CreateTimeStamp" Property Values From A Computer Object In AD?
Feb 4, 2010
how to pull the "modifytimestamp" and "CreateTimeStamp" property values from a computer object in AD? These properties are not AD objects but if I do properties("modifytimestamp").value, the return string is that of a collection. When I do properties("modifytimestamp").count it returns 0 as the value so therefore there is no index. How do I return these values?
Public Function GetADComputerData(ByVal ComputerName As String)
Dim DC As String = ""
Dim s_Domain() As String = Strings.Split(frmMain.Domain, ".")

I have a class called Item which contains all the information about all parts, finished goods, in process parts (parts made on site), purchased parts, and raw materials.
I have a Bill of Materials table which has the following columns (reflected in the BOM class)
ParentItem
ChildItem
ChildItemQty
Parent Items can only be Items which have subcomponents.
Child Items can be parts that are made on site, purchased parts that are bought ready made from other companies, or raw materials used to make a part that is made on site.
Parent Items and child Items both inherit the Items class.
I will limit the Parent item class to only items that are in the parent column of the BOM table. I believe I can limit that by doing a quick look up on a view which only shows the parent items.
I will limit the Child Item Class to only items that are in the child column of the BOM table. Same method to limit it by doing a quick look up on a view that shows only the child items.
That way, an instance of the BOM class will have all the detail information about any of it's components available whenever I need them.

I'm trying to create an export Excel/CSV function that will iterate through a custom object and first output the property names and then output the values. I want to use reflection only where necessary so I'm attempting to save the property names when I output the headers and then reuse them to print the values. Is this possible? I'm a little weary of using reflection in a loop but is there a better way?

I might be going about this all wrong, but i've been reading up on some stuff, and am venturing into stuff i've never dealt with before. example: when people do things like, dim xxx as new form1
then xxx.show...how do you design that xxx form? and get the objects placed where you want it? Design an object on form2. Say Panel, populate it the way I want it. Code it the way I want it.Then, say on form1, i push a button, and it will display the panel(on form2) on form1?

bare with me during this silly example. :-) Let's say I have a class like this:
Public Class Animal
Public iLegs as int32 ' Number of legs
Public bWings as Boolean ' Wings? Yes/No
End Class
And another class that inherits the "Animal" class and adds one more property:
Public Class ScaryAnimal
Inherits Animal
Public iScariness as int32 ' 0-100, how scary is it?
End Class
Now, if I have an instance of "Animal" with some values in it, and I decide I want to cast it to a ScaryAnimal for some reason, how do I do that without having to create a new instance of "ScaryAnimal" and copy each property value?Basically I'm looking for a way to do this, without having to write the lines marked with '*** below:

I 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.

I know how to handle a single objects property changed event very easily. I want to handle a objects property changed event that is part of another object.
Given Object:
[ObjectY = Y]
+ Public WithEvents X As ObjectX
I would like to do something like:
Private Sub XPropertyChanged() Handles Y.X.PropertyChanged
Right now I need to create a object that equals the object inside that object and then handle this variable pointers property changed, but that is just annoying.

I'm checking If a border's child property is not set to nothing or equal to a given element, but whenever I run the program, it says that it's set to nothing and crashes. Here's my code:
If Not Me.Child.Equals(Nothing) Then ...
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.

I'm building out a decommissioning application that will allow an individual to provide an computer name and the utility will go out and purge the computer record from various locations. I'm running into a problem when attempting to delete a computer object from SMS 2003. I found some good examples on the web of people utilizing a .Delete_ method via WMI. I'm working to convert that over to VB.NET; however the application is throwing an error stating that the "Delete_" method doesn't exist.
Wondering if someone could take a look through the code and see if I'm doing something obviously wrong. Or, if there is a better method to deleting a computer object from SMS 2003, I'd be interested in that as well.

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 am still quite new to VB, and the whole OOP concept (Self-taught), I haven't coded in 30+ years, so I have a great deal to learn/relearn. I hope my ignorance is not too apparent.I'd like to set property values with the same names as the controls of a form to the value of the forms text (or checked or whatever) value. It appears that the 'Parent.Controls' statement below is doing what I want, but I can't seem to get this to work. I don't know if I should be using a structure for this, but I hope it demonstrates my intensions.

I'm currently writing a HMI for an automated machine in VB.Net 2010. I have a custom class that turns a Border green or red depending on the value of an input on a remote I/O module.
The connection to the remote I/O module is through a COM object provided by the manufacturer. I have three remote connections, lets' call them g1, g2, and g3. They're of type Manufacturer.ConnectionObject.
I would like to specify, using a property that I can set in XAML, that instances of MyCustomBorder use g1, g2, or g3. Unfortunately, setting up a Property called g and typing 'g1' into the property field results in the message "Property value is not valid. Details: Property 'g' does not support String to Value conversion."

I need to implement a converter between String and the custom class, Manufacturer.ConnectionObject, but I have no idea how to accomplish this, especially since Manufacturer.ConnectionObject is part of a closed-to-me COM object.

I want to do translation recursively on all components in my form. So my function will start on the form. Before the recursion, it's obvious that I have to know what property containing the children that the current Object has.[code]...
The method I want to use it, I will check if the current object has property Items if not, check if it has property Tabs, and so on... Then the last fallback, check if it has property Controls.
Now the very question how could I check if the current object has specific Property?

I am creating a procedure and would like to know if I can pass the name of a property. I.e ComboBox1 so I can change the properties of that object. What I have done is create a procedure to populate a Combobox from my MySQL database. What I want to do now is populate the relevant Comboboxes without having to create a new procedure specifically for each combobox. I can create a procedure for each Combobox but the whole reason for procedures and functions are to minimize repetitive code and to make code easier to manage.
At the moment my procedure is ProcedureName(ComboBox1, "DatabaseName", "DatabaseField").
What I want to be able to do is do
ProcedureName(ComboBox1, "DatabaseName", "DatabaseField1").
ProcedureName(ComboBox2, "DatabaseName", "DatabaseField2").
ProcedureName(ComboBox3, "DatabaseName", "DatabaseField3").

I'm a C# coder, and I have trouble even reading VB.NET, so please forgive what may turn out to be an incredibly dumb question. But I have some code which looks like this:
CODE:
So, ignoring the fact that the syntax is probably wrong - how does VB.NET get the Name property from sourceObject? Inspecting it at run-time reveals that sourceObject is of a type that supports a property called Name with a getter, but what does VB.NET do in this case? Is there some extra code that is being generated by the compiler to somehow cast this automagically at run-time?

I found C# code for it here. So I tried
Public Function checkProperty(ByVal objectt As Object, ByVal propertyy As String) As Boolean
Dim type As Type = objectt.GetType
Return type.GetMethod(propertyy)
End Function
But it throws an error at type.GetMethod(propertyy) saying "Value of type 'System.Reflection.MethodInfo' cannot be converted to 'Boolean'."
What to do?
