View 9 RepliesI am loading an assembly using LoadFrom method on a file located in another folder. The assembly is called VisualCronAPI.dll. The assembly that I load has references to another assembly (VisualCron.dll) which contains some general type definitions used in VisualCronAPI. The file VisualCron.dll resides in the same folder as isualCronAPI.dll.When using LoadFrom I see in the output that VisualCron.dll is loaded. I am able to retrieve all methods in VisualCronAPI that uses parameters from VisualCron.dll. I am able to see parameter values However, when trying to create a Type using the following code I get an exception:
Dim t As Type = assem.GetType("VisualCron.NetworkCredentialClass, true)
Exception: Could not load type 'VisualCron.NetworkCredentialClass' from assembly 'VisualCronAPI, Version=1.0.3.32487, Culture=neutral, PublicKeyToken=55f7a52402de1c04'.

View 1 RepliesI'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 would like to enumerate an assembly's referenced assemblies and determine what should or should not possibly be included as a dependency in deploy scenarios.For obvious reasons I would want to exclude those assemblies that would be included by the CLR install.Is there any way to track back an assembly to being part of the default install of the CLR?

I created an application using VS2008. I am having a problem on only one PC. If I log on to the PC as the domain administrator, it deploys and runs just fine. If I log on as the user I get an error that basically says "The referenced assembly is not installed on your system. (Exception from HRESULT: 0x800736B3)". The error comes when running Venodr.appref-msl. VENDOR is the name of the application. The source is System.DeploymentSystem.Runtime.InteropServices.COMException I upgraded the user to a domain administrator and it still will not run. The PC is XP SP3
View 2 RepliesI have a stand-alone WinForms application, let's call it "Program A." Program A let's a user create a file and save some information to it. Program A also exposes some public classes.Another stand-alone WinForms application ("Program B") references Program A, and uses some of its public classes.
However, some of Program A's classes need to open the file the user created in order to retrieve data from it. In Program A, the location of the user's file is saved in the "Settings" (as user-scope settings of course) and are retrieved (this is a VB.NET app) via My.Settings.
This is all well and good until Program B runs - when it runs and uses the classes from Program A that need to read from Program A's My.Settings, the settings are blank - it's as if they were reset (as when you run Program A for the first time or under a new user account). Any application-scope settings are kept, but any user-scope settings are reset to their default values (whatever they were set to in the IDE when Program A was written).
[Code]...
Assume that the user has already run Program A at least once and opened a file, so Program A's My.Settings.UserFileName should be set.
When Program B calls Foo.GetStuff(), it doesn't return anything because My.Settings.UserFileName doesn't contain the user's file name - more accurately, it contains whatever the "default" value for that setting was (as set in the IDE when you set up the setting in the first place). But, if you turn around and launch Program A, it remembers the user's setting for UserFileName.
So - the question is: When calling a function in a referenced assembly, why are the user's settings not retained? Is there an explanation for the behavior I'm seeing, or am I missing something terribly obvious? Or perhaps I'm just going about this all wrong, and I shouldn't have made any of the public classes in Program A rely on anything in My.Settings in the first place?

View 2 RepliesWhat happened when parameter passing. Here is a test project I write.
Public Class Form1
'1.test string
Private Sub btnString_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnString.Click
Dim str1 As String = "x"
[Code] .....
From the project you can see, when pass integer type parameter (value type) into a method , if use ByVal keyword, the value won't change. If use ByRef keyword, the value will change (I can understand it, to my understanding, when using ByVal, It pass the value of the argument to the method; when using BvRef, it pass the address of the argument to the method, so the value can be rewrite)
Well, for the following two scenarios , I can't understand why.
String type is reference type, but it acts like integer type.
Val type is also reference type, but no matter what you use(ByVal or ByRef), the result will be the same.
So my question is what actually passed into method? What's the underlying mechanism about pass parameter? What's the effect of ByRef and ByVal to value type and reference type?
I'm working with legacy data, which often brings me one information splited in multiple columns. I'm trying to reproduce the following SQL query.[code]This own statement will run into the following exception:Variable 'line' of type 'SomeTable' referenced from scope '', but it is not defined. Any directions? I'm trying to avoid magic strings, but I'm always giving up to it (as using HQL the concatenation expression + like function works like a charm).

View 5 RepliesI 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 have a dll application that has its own app.config file associated with it. It has custom sectiongroups, sections, element collections, etc. The application name is WireShopAutomation.dll, so the built config ends up as WireShopAutomation.dll.config.The problem is that I seem to be unable to open the section group. The error message is:
"Could not load type 'WireShopAutomation.cfgSectionGroup_WireShopMain' from assembly 'WireShopAutomation'"
It seems to find the config file, but not the class handler for the section group and possibly the assembly itself. The class handler for this is in the same project as the application itself.The configSections section of the app.config file is as follows:
<configSections>
<sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >

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.
