I am debugging an assembly which I loaded dynamically with Assembly.Load(Byte[]), but I am facing some problems.First of all, I can't move the yellow arrow in Visual Studio 2010 to step into other lines of code, and also I am getiing exceptions ("Cannot find the method on the object instance.") when trying to do a quick watch on objects from a third party library (controls from Infragistics for example.)
Dim data = My.Computer.FileSystem.ReadAllBytes(file.FullName)
Assembly.Load(data)
When using Assembly.Load(String), everything works fine, and there are no problems.
EDIT: I tried loading the debugging symbols for my assembly with Assembly.Load(byte[]. byte[]), but it I sitll get Exceptions when trying to debug objects from third party libraries.
We loading and executing an assembly dynamically from code. While reading a dynamically loaded assembly how can we find an interface within the assembly which is marked (decorated) by another class like below
<ExternalDataExchange()> _ Public Interface IwfService Event firstEvent As EventHandler(Of ExternalDataEventArgs) End Interface
Here how can we find that we have interface "IwfService" which is marked with "ExternalDataExchange()" class.
When an error occurs in any of my .NET assemblies the user just gets a generic error saying "MyApp has encountered a problem and needs to close. We are sorry for the inconvenience." I would like the user to to see the error message and line number if possible.From what I understand you need to deploy the pdb file along with your assembly. I did that, but it had no effect. This is a Windows application.
Our company has an app that load their components by System.Reflection.Load (By the way, an awesome technique )But, we start to monitorate the application and detect a extrange grow up of memory (actually when our application still all day on air, their allocate memory on task manager is 200 MB plus memory) And all of our components (60 plus DLLs) is load by this technique.My doubt is how to deallocate this assemblies or how the best way to deallocate any assemblies loaded by the System.Reflection.Assemblie.Load method?
when I build I get this warning "Found conflicts between different versions of the same dependent assembly"the target for the application is any cpuI went through all refernced project/solutions - they are all any cpu, .net 3.5. There are some externally supplied dll from microsoft, sybase which I don't have control.
I am having a strange issue when building assembly's for one of my modules.I was getting errors when running on 64bit which I traced back to being related to the assembly being 32bit specific. Our modules are(or should) all be built to be bit agnostic.Running CorFlags.exe on the assembly showed the following.
My goal here is to get stack trace information from a dynamically loaded assembly. If the dynamically loaded assembly just throws the error back to the caller, the stack trace information doesn't tell you the location in the dynamic assembly where the error occurred. If I throw my own exception, passing in the original exception, it will get added as an inner exception and will have the information need. I'm trying to avoid changing all my dynamic assemblies to throw new exceptions.

I have a form which creates controls dynamically and adds event handlers by itself (already coded that part). As for now, I have a hidden table with the object list which loops through the controls and finds it by name (using the Me.Controls collection). How ever, does anyone knows if a dynamically created control may have a special unique code ?
I am trying to create a plugin system where plugins can be dynamicly loaded (we don't know how many there are, what their classes are called, ...)This is sample code for a plugin:
Code: Public Interface IPlugin Sub bla() Function bla3() As String End Interface
[code]....
This code SHOULD msgbox("yay") when it finds a type that implements my IPlugin interface. Yet it never finds one. I can't find what I did wrong. It gets to the debug.print("2"), but never gets past the "If GetType(IPlugin).IsAssignableFrom(t) Then".
I have the user control that is loaded dynamically. When the user save the data by clicking on the Save button, a raise event is passed.
Public Sub RaiseCloseEvent(ByVal sender As Object, ByVal e As System.EventArgs) RaiseEvent Close(sender, e) Debug.Print(String.Format("The control {{0}} was closed by {{1}}.", Me.Name, sender.ToString)) End Sub
In the save button I have called the RaiseCloseEvent as follows:
RaiseCloseEvent(sender, e)
Now, how can I close the user control form? Any Idea? I have used VB.Net language.
I have a database that dynamically loads from Access into a datagridview. I have to enter data manually into one column in this datagridview. I need to be able to perform calculations to this data, for example I need to sum the data in this column, sqaure it and substract it from individual sqaures of the data in the cells. I should be able to sum it sum(22,33,44,53,67,23)^2-sum(22^2,33^2,...23^2). The number of columns keep changing depending on the database I choose to load, so I need to code this dynamically too. I am not really a VB person. I did the same in excel using Visual Basic and I am trying to do it in this Visual Basic environment.I built a tool in excel(VBA) that do some statistical calculations and data analysis and I am trying to build the same in Visual Basic.
<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 I am loading an Assembly dynamically, then calling a method from it, I appear to be getting the method from Assembly executing before the code in the method that is calling it.It does not appear to be executing in a Serial manner as I would expect. Can anyone shine some light on why this might be happening. Below is some code to illustrate what I am seeing, the code from the some.dll assembly calls a method named PerformLookup. For testing I put a similar MessageBox type output with "PerformLookup Time: " as the text. What I end up seeing is:
First: "PerformLookup Time: 40:842" Second: "initIndex Time: 45:873" Imports System
Is it possible to immediately use code that is built in a dynamically built assembly?I would like to create an instance of an ENUM built using.http:[url]......
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 have recently upgraded an VB6 project to vs2008. I was almost finished when the following error occured. Unable to emit assembly: Referenced assembly AxInterop.MSFlexGridLib does not have a strong name Prior to this error appering, I tested my app several times and it was fine. Only after publishing it did the error appear. I have tried all solutions I could find, but nothing helps. I have read [URL]
Simple question that does not seem to be covered: If I use a lot of Debug.WriteLine statements in my code, will they be completely absent in my production version?
I mean: Is the compiler smart enough to not emit any code for those calls? Or would I have to surround them by #if DEBUG..#end if directives?
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 :
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 have two rich text boxes, and two buttons on my screen. The first button grabs HTML from a URL and then converts the HTML to XML which resides in rich text box 1.
The second button is to grab the XML from the rich text box1 and then parse it to grab all the input elements by their ID.
My issue is that my parser isn't doing anything. My guess is that I'm not quite getting the XML from the first rich text box.
What would be the best way to grab the XML from a rich text box load it into memory and then parse the XML to grab all the ID tags?

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?
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.
When ever I finish simple programs no matter what it is and i click to debug it it comes up"Error while trying to run project:could not load file or assembly"project name" or one of its dependencies.the module was expected to contain an assembly manifest"
sorry for my English, I don't speek well... I need to compile assembly in memory, that can compile another one. There is a form with one button. Here is a code of the form
Imports System Imports System.Threading Imports System.CodeDom Imports System.CodeDom.Compiler Imports System.Collections
