Public Class Foo

View 3 RepliesI want to send a serialized object from my server to the connected client. A little problem is that the BinaryFormatter needs the source assembly to deserialize the object properly.
View 2 RepliesBasically I have created an object that has a graphicspath as one of its properties... and i want to serialize it...
I was basically wondering if i could somehow automate the serializing of the GraphicsPath to another object (for the purposes of serializing since the graphicspath cannot be natively serialized)
eg serialize it to a list of the following class:
vb
<Serializable()> _
Public Class sPath
Public PathPoints() As PointF

I have a class called Truck and a form called frmTruck I have some code like this in a method. It recieves obj as Truck
Dim ms As New MemoryStream(1000)
Dim bf As New BinaryFormatter(Nothing, New StreamingContext(StreamingContextStates.Clone))
bf.Serialize(ms, obj)
To simplify my code, I have basically something like this for frmTruck:
public class frmTruck
private truckValue as Truck
public sub DoSomething()
[code]....
During the LoadTruckFromDatabase function I call the SerializeTruck method, here everything goes fine. But when I call the SerializeTruck just before End sub of DoSomething, it goes wrong I get an exception saying that frmTruck is not serializable My truckinstance doesn't have any references to frmTruck...

how to create a client/server... But I couldn't... I don't want anything fancy. Just want the client to send the server 4 numbers, depending on the user's choice; after that, the server would turn off the pc, restart it, etc. It all depends on the number received. Is there a rather "simple" way to do it? If it's not to much trouble you could use Atheist's example. (Btw I don't understand the code and, yes, I've checked on [URL])
