There are three assemblies: A, B and C.
A has: class Button.
B has: instance of Button (call it oButton).
C has: oButton.
C wants to have: assembly oButton is in (B).
I know I can get an assembly via a type (e.g.: "System.Reflection.Assembly.GetAssembly(type)"), however, I would like to get an assembly some reference belongs to.

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 developed an app and an installer for it and everything works fine. I now feel I should add a bit of obfuscation to the code before it gets released into the wild. VS2010 comes with the CE edition of dotfuscator so I've run it and it produced an .exe in a 'Dotfuscated' folder. Do I just replace all four 'Primary output from. custom actions with the assembly from the Dotfuscator folder or am I missing something?

When I try to play an audio file through DirectX, that isn't my development machine, I receive this error.
The DirectX library I'm using is Microsoft.DirectX.AudioVideoPlayback.dll.
I include the library when I build the application and I thought that would work. Both PCs have the same version of DirectX installed. So what else do I need to install?
The app itself is meant to run on a USB, so I can't install it, but I'm able to install 3rd party libraries during the initial load.
Currently I have a need to reference a class library dll that is not located in the same directory as the exe nor its subdirectories. Can anyone point me in the right direction on this? Are there any good articles or tutorials on it? I have been looking through my .Net books and some go into details in a different direction and none that I have seem to cover it. To be honest, if theres a nice tutorial or article on this topic with sample code to look at, that would be ideal at this point in my project (Im literally presenting on it twice tomorrow).
I have to admit that Im fairly ignorant of this topic, but its my understanding that I should be able to accomplish this using the assemblyBinding elements in the application configuration. If I do use a codebase approach with the app config, am I suppose to do something in the exe code to read the config and load? The class library that Im refrencing am I supposed to have any special methods or classes in it to make this work? I think I have more questions than answers.
If you want more of the nitty-gritty details on the current scenario, here it is:
I have an executable Ive developed (well call this myApp.exe). I also have a centralized data-accessing class library (well call this appData.dll). This exe actually utilizes a framework Ive designed to run from within a third-party companys application. To ensure the myApp.exe is more maintainable and accessible, it will be located separately from the framework.dll and the appData.dll. The framework.dll will most likely reside in the same directory as the third-party exe, but separate from the appData.dll and myApp.exe. So I was considering applying the assemblyBinding elements in the application configuration files for the myApp.exe pointing toward the framework.dll and the appData.dll while that for the framework.dll will be pointing toward the appData.dll (this is why the data access library file is central between the two).
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.
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.

We have upgraded our project from Visual Studio 2008 to Visual Studio 2010 without any issues until now. Our project contains a folder call Libraries which contains different versions of Oracle ODP.NET DLL's as well as different versions of Telerik DLL's. Our project contains references to one of the versions of each. The problem is once we remove the reference and re-add it by browsing to the new version, again inside the Libraries folder inside the project, it adds the reference, but to the same version we just removed. We can even copy the DLL to our desktop, remove the reference and add to the new one on our desktop and it still will point to the Libraries folder version???. The only we we can actual change the reference to the new DLL is by manually changing the path in the .vbproj file, which is obviously not going to work for us. The same behaviour worked perfectly in VS 2008. We switch our references quite often, when new versions come out, but also far more often to QA different versions of ODP.NET and Telerik Control DLL's, so manually editing the .vbproj file is becoming quickly cumbersome. If I browse to a specific version at a specific path, Visual Studio should ALWAYS do what I'm telling it to do..
I did some seaching and came across a few other people with the same issue. This better not be as designed and if it's a bug, which I believe it to be, when will it be fixed?[URL]..

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?
One of them is giving us trouble in only 1 spot out of the 4 spots we use it at:The trouble spot is a windows form project that uses reflection to dynamically load some DLLs that run long running processes. One of these long running processes is an agent that relies on one of our vender DLLsWe're getting the missing assembly exception at the point where we first enter a function that references the library. I already checked the silly things such as if we had forgotten to move a reference from the old version to the new version, but that's not the case. I also checked the bin directory of the project and the assembly is there.
