I 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 RepliesI need a way to transfer a compiled assembly from client to the server and be able to store that in the database or in a file in such a way that I can grab those bytes on the "to" side and re-load assembly. Is there a way to do it. To clarify, I have a winforms application that will generate code and compile it based on some metadata. Now I need to be able to transfer this to a web site and store it somehow, but I don't want a dll (because it can be de-compiled). I would then have a "server" program on the to side, that would load this in memory. I could just transfer encrypted source code, but I thought I could just transfer compiled assembly.
View 4 RepliesThe general idea of whats going on is i am trying to transfer a structure from one project to another using binary and sending through a TCP Stream. What I Did:In my server i serialized the structure Maps(Map) to a temp file. Then I read all the bytes from the temp file to my buffer and sent it off to my client project.

Is this possible?
Public Class Foo
public var as string
public sub Load(byval filename as string)

Up until now i've had a function that that returns Foo as Object (I'm trying to make the serialize / deserialize process general so I can just copy and paste and avoid explicitly setting each variable)

View 3 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...
I am trying to serialize object in method binary mode. However, I would like to get a file in human-unreadable format. which means i want to encrypt file. In my memory, if i want to write text into binary file in C, when I set writing mode as binary, I will get a file in human-unreadable format, but in .net, I can't get that.

Each business object has a matching object that contains sql calls. I'd like to restrict these sql objects in a way where they can only be used by the matching business object. How can this be achieved?
Update Greg brought up the point about testability. Since the SqlObjects will contain very business-process specific sql I don't want them reused in multiple buiness objects. (Basic CRUD operations are all code-generated) Is there a way to make the SqlObjects accessible to only one business object in the business assembly (like yshuditelu and Greg Beech showed) AND expose the SqlObjects to the unit testing assembly?

View 2 RepliesI have an assembly in VB .NET 2.0 that I am trying to use to call a webservice.This will be COM visible, and return the results to Access in VBA.The .NET Assembly passes all tests and executes perfectly.I was experiencing "Object does not support this property or method" errors when calling the methods from VBA.I broke it down to a certain object that was being returned and added some test methods to the .NET DLL.There is a "Patient" object I want to return.It looks like this (made it very very simple to test it):

I have an RDLC report that I am rendering directly to the Response Stream as PDF (rather than using the ReportViewer). In the code that renders the report, it's DataSource is bound to a List(Of ClassA) objects defined in a custom assembly. This seems to work for the most part. My problem is that I can't seem to handle the situation where a nested object is null. For example, given ClassA and ClassB (the nested object) defined as follows:
Public Class ClassA
Public Id As Integer
Public Name As String
[Code]....
the report displays "#Error" if TheNestedObject is null. If TheNestedObject is not null, it correctly displays the Name.

View 1 RepliesI receive this error as "Assembly Load Error" whenever adding a form or other object that has to be inherited.
"Unable to load assembly. Ensure that the file is a valid .net Framwork assembly"
I am loading an Assembly using Assembly.LoadFrom() as the assemblies are located in a different path from Application Base directory.
Dim oAssembly As Assembly = _
Assembly.LoadFrom("C:\MyFolder\" + ddlXlate.SelectedItem.ToString() + ".dll")
And I consume a Type from that assembly without any problem:
oXML = CType(oAssembly.CreateInstance(sBaseType + ".XlateContainer"), _
XlateBase.XlateContainer)
However, the problem occurs when I try to use a Type from this assembly from within another method like the one below:
oComboBox.DataSource = _
[Enum].GetValues(Type.GetType(sType + "+ItemEnum," + sAssemblyName))
sAssemblyName is the one I loaded using LoadFrom() actually. After it said it cannot find the assembly, I used AssemblyResolve event which solved my problem :Subscribing AssemblyResolve event :
AddHandler AppDomain.CurrentDomain.AssemblyResolve, _
AddressOf MyResolveEventHandler
Event Handler Method:
Private Shared Function MyResolveEventHandler(ByVal sender As Object, _
ByVal args As ResolveEventArgs) As Assembly
Return Assembly.LoadFrom("C:\PSIOBJ\" + args.Name + ".dll")
End Function
And I thought maybe the error occurs because it cannot find a dependent assembly defined in assembly manifest file I loaded using LoadFrom() already but when I checked the args.Name, I saw it was trying to load same assembly and after that it worked without any problem. So basically a type in the loaded assembly cannot be found before the event adding change.
My old code was using AppDomain.CurrentDomain.Load() and Assembly.Load() methods and they were working fine without the AssemblyResolve event. I was able to reach types in dynamically loaded Assembly from every where within the same AppDomain.
LoadFrom() can find dependencies automatically within the same requested assembly path and that couldn't be problem as everything this dll needs was there. So at first it looked like a AppDomain problem to me as it looks like it seems it can reach assemblies from Load context instead of LoadFrom context and I am now using LoadFrom context.But now it seems I should pass oAssembly instance evertwhere to use any type from the loaded assembly?Doesn't it load the assembly where I can reach it everywhere (same AppDomain) using simple Type.GetType(...) method?
I'm wanting to include a system tray icon in my WPF project, and found this resource:[URL]..which looks like it will work beautifully, but it's written for C# and I'm using VB.net for this project. I downloaded his project and built the notifyicon as a DLL, then added as a reference to my project.
It throws up an error: Unable to emit assembly: Referenced assembly 'Hardcodet.Wpf.TaskbarNotification' does not have a strong name So I'm trying to figure out the best way to proceed. Do I need to strong name it, or is there a better way to do this?
I've got an exception when I deployed my application: "the located assembly's manifest does not match the assembly reference" What I remember is changing the project name from the previous source code, does it affect that much?
View 1 RepliesI have created several DLL (.NET) libraries that are used in several projects. In these DLL libraries I want to know/retrieve which assembly (EXE) calls/uses the library, so if possible I want to know info like assembly name (EXE), strong name, version number, etc.

I have written a .net assembly which plugs into to a third party COM application. The .net assembly is COM visible to the third party application. However this .net assembly references other regular assemblies. If I put these assemblies in the GAC the COM visibile assembly sees them without a problem. However for various reasons I do not want to put them into the GAC but I cannot get my COM visible assembly to see the other assemblies when they are in other locations. I have tried putting them in the same directory as the COM visible assembly. I have tried putting them in the same directory as the third party app's exe but neither of these work.

Since, it's possible for anyone to name an assembly starting with 'System', checking for 'System' is not a satisfactory solution.
Alternatively, if that's not possible, how about checking the modules in an assembly?
I am building a dll-Assemby A which references another Assembly B. Assembly B is strongly named and installed in the GAC of my development computer. An other computer will not have assembly B installed in the GAC.
Question: If i handle strongly named assembly B like a private assembly and copying it into the bin-directory by specifying local copy = true in the properties-window, will the programm run on the other computer?
