Ignoring Assembly Info When Deserializing
Feb 5, 2011
I'm writing a solution in VB.NET that consists of a number of different components (UI manager, Outlook add-in, etc.). In the main UI program I'm serializing out an arraylist to a data file that contains the data the other components will need to do their jobs. That part works fine, and I can serialize and deserialize with no problem. Now I want to read (deserialize ) in the data in my Outlook add-in, and I ran into the dreaded 'Unable to find assembly' issue where it's looking for the original assembly that serialized the data. I found a hint for workaround

I 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.
NB: Examples may be in C# or VB. I use both languages.

First of all let me say im not trying to change the assembly of the main app (done by going to the properties etc..) I have an application which (On press of a button) creates a new file (Newfile.exe) i would like the user to be able to specify the new files version info etc... I have tried a DLL called Flash Dissasembler which I did not like.

How to set current year in AssemblyInfo file?
I used
Instead of this:
<Assembly: AssemblyCopyright("Copyright 2012, Company Name.")>
tried this:
<Assembly: AssemblyCopyright("Copyright" + DateTime.Now.Year.ToString() + ", Company Name.")>
I get invalid constant error.
I don't want to use registry key entries, what is the optimum way of doing this? (so that when a user right clicks on EXE & looks for assembly information can see current year).

When running setup to install published program, the following message occurs: System Update Required: Unable to install or run the applicaiton. The application requires that asssembly CrystalDecisions.CrystalReports.Engine Version 10.2.3600.0 be install in the Global Assembly Cache (GAC) first. This version is listed in the references of the program and in my mind, be included in build. How do I get by this error?

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?

According to a mspress book (MCTS for Exam 70-536 .NET 2.0): You might have version compatibility issues if you ever attempt to deserialize an object that has been serialized by an earlier version of your application. Specifically, if you add a member to a custom class and attempt to deserialize an object that lacks that member, the runtime will throw an exception. In other words, if you add a member to a class in version 3.1 of your application, it will not be able to deserialize an object created by version 3.0 of your application.
Now... As curious as I am I went and created a project, serialized a class, added a new member and attempted to deserialize the class to the new object. To my surprise it worked and the newly created member was set to null by default (even if it had another default value).

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?

This is my first post on here--I've been teaching myself VB via forums like this and MSDN for about 2 years now. I'm programming a computerized economics experiment, and I'm using a communications package that a guy I worked with developed. He and I have been going back and forth trying to figure out what the heck is going on.
The upshot of the communications package is that there's a serializeable MQMessage class that we send back and forth, essentially just a package of an integer (Type), string (Text), and Object (Data). Most of the time, this goes according to plan.
The problem is this: If the client receives two or more messages back-to-back, the client stops raising the MessageArrived event. (and presumably, the same would hold true for the server--I should test this, but jeez-oh-man, I've been running test after test for the last week).It's still connected, as on disconnect it throws the "Socket forcibly closed" exception. When it receives multiple messages sequentially, it's still receiving the data, it just never knows when the first message ends, and the buffer just keeps filling and filling. The problem seems to be that it can never successfully Deserialize the MQMessage object, and so it returns Nothing on the getCompletedMessage function and just keeps adding to the buffer (ABuffer.Length goes 1024, 2048, etc.).

I'm saving potentially very large amounts of data to disk as a single serialized class. But there is a sub class that I would like to be able to retrieve and write back to the disk without having to read the entire file or write back the entire file. Trust me, my reasons for doing this are good, and the design behind this is more than correct.In VB6 this is very easily done. A single statement gets the portion of the data you want from the front of the file and saves it straight to the Type it belongs to, flawlessly. Likewise, if the dimensions of the data haven't changed, but only the values, then Put can be used to save it right back to the file without disturbing the integrity of the entire file.When needed, the entire file is read into a larger structure, and the entire file is put back, but only when necessary. Most of the time the only information being read from and written to the file are in the first few hundred kilobytes of the file.
Now that I've got serialization working, I'm trying to use it to read (deserialize) only the first member of the class serialized to disk. I haven't been able to find any examples of this anywhere that have lead me toward making the sort of progress I'm hoping for.So I suppose the first question is this: Is it possible to read only part of a serialized class from the open file stream? Specifically, in one case I want to read the first two integers stored in the class. In another case I want to read only the first block (sub class) from the open file stream. In both cases I do not want to read the entire file, but just what I'm interested in starting from block 0. I don't need to write back the integers to the first file, but I do need to write back the block to the second.Assuming that the answer to the above is yes. My second question would then be: How is this done? I want to work with the file stream already open rather than opening and closing file streams over and over.I

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.

The following (abysmal) code demonstrates how standard serialize/de-serialize in VB loses the CR when on de-serialize. This can be overcome by applying 'XmlAttribute(DataType:="string")' to Description. Why does it do this? I would like to fix this without applying a 'LF' -> 'CR''LF' in every affected class. This is fixing a bug in existing XML files generated without the XmlAttribute!

I am having the same issues as per this question: WCF not deserializing JSON input..I am at a loss and desperate for a solution. I have scoured the net for answers, but I have found only this question that matches my exact problem. My datacontract parameter is also nothing when the service starts.I have tried the points of the answer in the question above, but they provide me with no clues (The web service executes OK -I am not getting any exceptions - and I can't see what the deserializer is doing - or not doing as the case may be).I am using POST, due to the size of the nested JSON.If more detailed information is needed, I will provide it on request.[code]

I'm developing a program that captures a bunch of information entered by a user on a tab form into five different structured arrays. I want the data to be saved into a single file and reloaded by the program into a similarly built series of structured arrays through a different form.If I understand the process of serializing collections right, I create a single ArrayList variable to capture each of the five Structured arrays.[code]
1. Do I have to declare one variable of the same type as the one in the first element of the ArrayList, or does having the public variable declared in the Class that's going to take this information already cover that?
2. Once I deserialize into the newly declared Rules ArrayList in the new form, is it a simple matter of setting the duplicated variables in the new form equal to the relevant element in the ArrayList? For example, if I have a new Public Roster As RosterDesc variable declared, can I set it equal to Rules(0) and it would automatically populate every element in the same order as they were created in the original form?
