Both of your "type1" and "type2" classes have fields in common. Ok, so those have to be broken out into something that is common between those two types, either an Interface implementation or a base class that they both inherit from.
You will then be able to pass your "type1" and "type2" class instances as either that interface or base class for the method to use. For example, an interface version would look something like:
Public Interface SomeInterface
Property SomeProperty As String
Property AnotherProperty As Int
End Interface
And both of your "types" would have to implement the interface:
Public Class Type1 Implements SomeInterface
...
End Class
Public Class Type2 Implements SomeInterface
...
End Class
When you define your method that has to accept instances of these two classes, you use the interface to define the parameter expected:
Public Sub MyMethod(ByVal parameter As SomeInterface)
End Sub
The method is saying "I need something that implements this interface". It's a contract where the method expects the object passed in as "parameter" to implement a know interface, guaranteeing the properties defined in the interface will be there in the object that is passed in.
When you go to call this method, you're saying this is an instance of Type1, but since it implements this interface, treat this object as this interface type, not as the Type1 class.
Dim myInstance As New Type1
...
MyMethod(myInstance)

Easy way is to put those details in their own class, and make that new class part of type1 and type2.
Public Class McBoatFace
Property Num As Integer
Property vl As String
End Class
Public Class Type1
Property Boat As McBoatFace
End Class
Public Class Type2
Property Boat As McBoatFace
End Class
Sub Marine(Boat As McBoatFace)
End Sub
A less easy, but cleaner way would be implementing the McBoatface-class as an interface, and to pass the interface to the sub. Another way to make it cleaner is by putting the Boat-property into a new Type0-class, and inherit Type1 and Type2 from it; makes the property appear in both classes.

The types type1 and type2 are totally different types , but both have the fields that I use on the sub.

I suppose that there is a possible solution - but for this you should give more information about your issue ...
Perhaps you write something more about those 2 types and what is common to them.
In my opinion each of your types derive from Object and so you should be able to identify each type in your method ...
But ... as I wrote before ... more Info required ...

I am creating a tool to delete user profiles by age on all windows 7 and windows 10 devices on our domains. I have it working using this filter ("(objectClass=computer)") but want to refine that to only get windows 7 and windows 10 devices because my department manages desktops/laptops not servers. In order to make the tool more efficient and not attempt to connect to devices I don't have admin access to.
So I tried this filter... mySearcher.Filter = "(&(objectClass=computer)(operatingSystemVersion=*server*))" my thought was to do something like this if OS IsNot Windows Server 2012 or Windows Server 2008 then do something.
I loaded the operatingSystem property but can't get it to display. I have tried it in the datagridview and when that didn't work I just tried to do a consolewriteline and that didn't work either. I want to test my concept before adding the code to use WMI to delete profiles by just displaying the hostname and OS version to make sure it is pulling the information from AD and not giving me servers. Can someone help? Here is the code(I am just working with the v06 domain at the moment):
Dim mySearcher As DirectorySearcher = New DirectorySearcher(enTry)
mySearcher.PropertiesToLoad.Add("dNSHostName")
mySearcher.PropertiesToLoad.Add("operatingSystem")
mySearcher.PropertiesToLoad.Add("operatingSystemVersion")
mySearcher.Filter = "(&(objectClass=computer)(operatingSystem=*server*))" '("(objectClass=computer)")
Dim resEnt As SearchResult
For Each resEnt In mySearcher.FindAll()
Select Case dMain
Case "v06"
Try
hostName = GetProperty(resEnt, "dNSHostName")
OSystem = GetProperty(resEnt, "operatingSystem")
Dim result1 As Net.NetworkInformation.PingReply = ping.Send(hostName, 1000)
If result1.Status = Net.NetworkInformation.IPStatus.Success Then
Dim row2 As String() = New String() {hostName, "N/A", OSystem}
dgvLocal.Rows.Add(row2)
Else
My.Computer.FileSystem.WriteAllText("C:\ExodusErrorLog.txt", hostName & " - Device is not pingable!" & vbCrLf & vbCrLf, True)
End If
Catch ex As Exception
My.Computer.FileSystem.WriteAllText("C:\ExodusErrorLog.txt", hostName & " - " & ex.Message & vbCrLf & vbCrLf, True)
End Try
Case "v07.med.va.gov"
End Select
Next

Here's an alternative to the solution you seek; get a full list of all the PC's, and then use LINQ to query out the ones that are servers. You may also get a better query from a network-admin; it is querying the AD after all.

Learning Threading, Invoke, Delegate and MethodInvoker ...
0) I use Visual Basic 2017.
1) I can press Button1 or Button2 randomly: works!
2) After the first round I can only press Button2. Button1 no longer works!
3) Who can indicate IN THE CODE where the error is?
4) I search for information everywhere on the internet, but what exactly Invoke, Delegate and MethodInvoker do, is not completely clear to me … 
5) Thank you …

You're initializing the number in one sub, but not the other.
Private Sub CountUp()
Number1 = 0
Do Until Number1 = 1000
Number1 = Number1 + 1
UpdateLabel1Text(Number1)
Loop
End Sub Enjoy the festivities and keep on learning, you're doing well

It's not, we all have those moments; you're searching for an error, and there clearly is none. I wasn't searching for one, just looking for the difference that you told me would be there.
It was a good formulated question with description of expected and actual results.

There is no "complete" list; not every application registers an uninstaller with Windows.

The SQL code am using is
Private Sub Command8_Click()
Dim SQL As String
SQL = "SELECT tblVisit.PatientID, tblPatients.Firstname, tblPatients.Lastname" _
& "DateDiff('yyyy',[tblPatients]![Birthday],Now()) AS Age, tblVisit.[Date Visit]" _
& "tblVisit.Diagnosis" _
& "[First Name] & ' ' & [Last Name] AS [Prescriber Names] FROM tblPatients INNER JOIN (tblDoctor INNER JOIN tblVisit ON tblDoctor.DoctorID = tblVisit.DoctorID) ON tblPatients.PatientID = tblVisit.PatientID" _
& "WHERE [Firstname] = '" & Me.txtKeywords & "' "
Me.subClientList.Form.RecordSource = SQL
Me.subClientList.Form.Requery
End Sub
The error that is coming up is..
The error is runtime error '3075'
syntax error (missing operator) in query expression 'tblvist'.[DateVisit]tblVist.Diagnosis[First Name]& ' ' [Last Name]'
The
[First Name]& ' ' [Last Name]' are from a table prescribers and the
tblVist.Diagnosis is an attachment column in the table visit and the
tblvist'.[DateVisit]tblVist is a column of visit dates

I think you need a comma after each item.

You're using string concatenation to build the query. This alone is a bad idea as you are very vulnerable to making mistakes and you open the database up to being destroyed due to SQL Injection attacks.
Your code looks like this:
SQL = "SELECT tblVisit.PatientID, tblPatients.Firstname, tblPatients.Lastname" _
& "DateDiff('yyyy',[tblPatients]![Birthday],Now()) AS Age, tblVisit.[Date Visit]" _
& "tblVisit.Diagnosis" _
& "[First Name] & ' ' & [Last Name] AS [Prescriber Names] FROM tblPatients INNER JOIN (tblDoctor INNER JOIN tblVisit ON tblDoctor.DoctorID = tblVisit.DoctorID) ON tblPatients.PatientID = tblVisit.PatientID" _
& "WHERE [Firstname] = '" & Me.txtKeywords & "' "
This results in a query string that looks like this. Examine this query statement closely and you're going to find lots of problems. You're missing spaces between words and messed up the concatenation in places.
SELECT tblVisit.PatientID, tblPatients.Firstname, tblPatients.LastnameDateDiff('yyyy',[tblPatients]![Birthday],Now()) AS Age, tblVisit.[Date Visit]tblVisit.Diagnosis[First Name] & ' ' & [Last Name] AS [Prescriber Names] FROM tblPatients INNER JOIN (tblDoctor INNER JOIN tblVisit ON tblDoctor.DoctorID = tblVisit.DoctorID) ON tblPatients.PatientID = tblVisit.PatientIDWHERE [Firstname] = 'SqlInjectionAttack' "
Now, Google for "SQL Injection Attack" to find out why what you did was so wrong, then Goggle for "VB.NET SQL parameterized queries" to find out what to do about it.

The "Calculate Order" button will do the total order. Then I have to manually put the amount on the "Amount Paid" textbox to get the change. Now, what I wanted to do is to assign the enter key so that I can just press enter after typing the amount and don't have to hover the mouse and click the "Amount Paid" button. I don't know the codes for it, and where should i put the codes, on the textbox or on the button? The accept button property is already used on my "Log in" button. Please help me. xD Thanks in advance!

Hello !
Is there any fast way to create a list of obj1(Integer,string) , where the first field is an integer from 1-2000 , and the second field is the same string. , so the list should be : (1,"a") , (2,"a"),(3,"a")........(2000,"a").
I know that with a for loop can I create this , but i'm asking if there's a more fast way.
Thank you !
