How To Make A Vb 2005 Class Assembly
Jul 26, 2010
I am a java developer that inherited a vb.net web application. This app relies on a VB class assembly that builds in to a dll. I have made some changes to this class assembly but I cant seem to get the vb.net app to pick up the changes. I thought that using regsvr32.exe or regasm.exe would do the trick but after reading a bit more they don't appear to do what I need.
When vb.net uses code such as this import where is it getting the reference to "MyClassName"?
<% Import namespace="MyClassName" %>

Ok so here's the story. I have an array of Assemblies which are initiated by [Assembly].LoadFrom() that load a number of DLL's. Upon initialising, a method called InitMain (from the DLL!) is called, which sets a number of variables outside of this method, like here:
Public Class Example
Dim C As Integer = 0
Public Sub InitMain()
C = 50
End Sub
[Code]...
If I call the method Test using that same array of Assemblies somewhere later in the main application (like pressing a button or something to trigger it), it will pop up a messagebox with that says: "C = 0"Why is this? Is it fixable without any odd workarounds?

Two of us at our company worked on a VB project. I developed the GUI interface. Another programmer developed some of the Classes that are also part of the project/Solution. Our manager wants to see as part of the 'Help/About' drop down, the version of the GUI application as well as the Class that the other programmer wrote. We are on the third modification of my GUI application, but the 8th version of the class that the other programmer wrote. Is there some way that the GUI application can get the 'Assembly Version' information for a class that may not necessarily exeuting at any given time?

I have . VB.NET DLL that I have made COM visible and it works fine.However, I've now added another class which I also want to expose to COM but I am now getting an erro when I build it:
Quote:
Error1The assembly {...} could not be converted to a type library. Type library exporter encountered an error while processing 'TOPSMileageLookup.JobMileage, TOPSMileageLookup'. Error: Type 'JobMileage' and type 'Job' both have the same UUID.
JobMileage is the name of the original class I had that is COM visible and it worked fine when it was on it's own. Job is the name of the new class.Now, the obvious suspician is that I have copied over my COM GUID's but I can assure you that they are most certainly different. But what else could it be?

I have a Visual Studio 2008 solution with project A referencing project B as a project reference. Project B references System.Data.Linq, but project A does not. Everything compiles and runs fine. I like this arrangement because avoiding a reference to System.Data.Linq in project A ensures that it uses project B methods instead of directly accessign System.Data.Linq methods, which I want to avoid.

I have a solution with two projects within:
Company.Project.vbproj
Company.Project.Tests.vbproj
Within the Company.Project.vbproj assembly, I have a class FriendClass.vb which scope is Friend (internal in C#).Now I wish to test this FriendClass.vb from within the Company.Project.Tests.vbproj assembly. I know about the InternalsVisibleToAttribute, but that is not an option in Visual Basic .NET 2.0, as it is only available with C#, in .NET 2.0 (see here).I would like to create myself a proxy class using this internal FriendClass from within my testing assembly, so that I could instantiate it and do the testings accordingly.

I got warnings on my project, does somebody know how to reference this assembly. this is probably because the project has these crm.mytextbox type textboxes and other controls instead of normal system.windows.forms.textbox.Warning1Could not find type 'crm.Mycombox'. Please make sure that the assembly that contains this type is referenced.If this type is a part of your development project, make sure that the project has been successfully built.00

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?

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 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.

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?
