Use Reflection To Unit-test An Internal Class Within An Assembly When The InternalsVisibleToAttribute Is Not An Option?
Aug 26, 2010I 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.

View 1 RepliesChange The Namespace Of A Highly Referenced Class?
May 12, 2009I am attempting to move a highly referenced class from one namespace to another. Simply moving the file into the new project which has a different root namespace results in over 1100 errors throughout my solution.Some references to the class involve fully qualified namescape referencing and others involve the importing of the namespace.
I have tried using a refactoring tool (Refactor Pro) to rename the namespace, in the hope all references to the class would change, but this resulted in the aforementioned problem.Anyone have ideas of how to tackle this challenge without needing to drill into every file manually and changing the fully qualified namespace or importing the new one if it doesn't exist already?
Use A Static Variable That Is Referenced To In The Class's Children?
Oct 11, 2009how to word this, as it is it's complex to understand the concept of the idea. Basically, I'm trying to use an interpreter pattern, based off of the code I used in php. In php the code is:
abstract class Expression {
private static $keycount=0;
private $key;
[code]......
The problem I'm having is that the static variable is blank for each child using it. How can I have it where one child increases the keycount,and ALL of the children have the new keycount variable?
Access Byte Array Within C# Class Referenced In .net Project?
Jun 6, 2011I am trying to instantiate a c# class whose project is referenced within a vb.net project.By providing the following declaration/instantiation of the class, I hoped to be able to access the instantiated classes publicly declared byte array within a vb.net module.The compiler won't let me. I get the message Access of shared member, constant member, enum member or nested type through an instance; qualifying expression will not be evaluated. It wants me to replace the reference to the instantiated class and public member frameData() with the general Class definition name. Why can't I access frameData through the instantiated variable rxFrame?
View 5 RepliesCan't Access Class Library Methods / Properties When Referenced As A DLL
Oct 15, 2009I've created a class library and built a dll (release build). I've then referenced the DLL in another project (I've tried several). I can see the namespace and classes in Object Browser and I can declare instances of the classes but I cannot use or see any of the methods or properties! there is no IntelliSense whatsoever and calling the methods manualy results in a 'Declaration expected' error.
Within the class library solution I have a unit test project referencing the class library project which works all works fine (and all the tests pass).
Can anyone provide any pointers to what might be going wrong here? I've built plenty of dlls in the past and have had no trouble referencing them at all.[code]...
Create An Application Without Distributing A Referenced Class Library
Mar 1, 2011I am using VB .NET 2003. I have created a user defined Class Library and created a reference to it in my application. Is there a way I can compile the application so that the Class Library DLL is embedded into the application? I would really like to be able to distribute the application without having to distribute the DLL as a second a file.
In other words, I made a New Class Library lets say called TEST. I developed a new class within this library called MYCLASS. I built the Library TEST and created TEST.DLL. I then made a new visual basic project called APP1. I added a reference to TEST.DLL. I now can use TEST.MYCLASS within my APP1 project. The application APP1.EXE will run in the test environment, but if I move it to the runtime environment it will give me an error "File or assembly name TEST or one of its dependencies was not found". To correct this error I can place TEST.DLL in the directory where APP1.EXE resides. I would prefer not to have to put TEST.DLL in the directory. Can I easily compile it into APP1?
VS 2008 Handling Exceptions In Referenced Class Libraries
Jun 8, 2010i created a Class library (.dll) and loaded it as reference into a main project. In the code for the class i've handled exceptions using try..catch subs, however when debugging the main project exceptions that are handled in the DLL still get thrown! (the class ".vb" file gets loaded into the debugger and the line of the exception shows up)
Up till now i've found it useful that when an unhandled error occurs in the imported reference, it shows up in the main project with tracing back to the referenced class. But i dont want the exceptions that are handled in the reference class to be thrown when debugging the main project!
As you can see the exception thrown was handled with try...catch this class exception.vb belongs to the project that created the class library (.DLL that i referenced). i didnt even load the project that built the reference so it amazes me that it could find the coding class to begin with.
C# - Retrieve Internal Member Of Nested Class By Reflection
Jun 1, 2012I know that the MenuItem class contains an internal class named MenuItemData, which contains itself an internal member named onDrawItem. Given a MenuItem, I want to retrieve the object corresponding to the member onDrawItem. But all I manage to do is to get the FieldInfo, not the object itself.
Here is my code:
Dim obj As Object
Dim fi As FieldInfo
Dim item as System.Windows.Forms.MenuItem
Dim mType As System.Type
[Code] .....
When reaching the last line, I get an error saying something like that (it's traduced):
The field 'onDrawItem' défined in type 'System.Windows.Forms.MenuItem+MenuItemData' is not a field of the target object of type 'System.Windows.Forms.MenuItem. I don't know what object to pass to the GetValue function on the last line. My goal is to remove the base eventHandler of the menuItem, named DrawItem. See this post and the function RemoveClickEventin the accepted answer for a better understanding.

SqlClient.SqlDataAdapter.Update() Performs Very Slowly?
Jun 29, 2011I am porting VB.Net 2 code (VS 2005) to VB.Net 4 (VS 2010). So far things have been going relatively smooth. However, in testing my new ported code, I came across a strange behavior. In VS 2005 (.Net 2), I have a DataTable filled with data. I then use a DataAdapter to send updates back to the SQL Server. When I perform the qlClient.SqlDataAdapter.Update() command, it execute in roughly 4 seconds. The same code,on the same table in VS 2010 (.Net 4) runs in 1 Minute 17 Seconds. This is completely unacceptable. However, I have no clue as to why it is happening. The .Update() method is an internal command, not one that I modified in any way. It does not error out, it's just painfully slow.
View 1 RepliesMake A Program Which Basically Performs Unit Conversion?
Jun 18, 2012Im trying to make a program which basically performs unit conversion. I have basically made two text boxes, one for the S.I. Units and the other for British Units. The general idea is that when i input any number in the S.I. Unit text box, it should display the answer in British Unit text Box and similiarly if i input any number in British Unit Textbox, the answer should be displayed in S.I.Unit textbox. Now the problem lies here that the code that i created is by using if else. now the compiler automatically gives me the correct result in the British box when i input the value in the s.i. unit box, but when i input the value in the british text box, it gives an error that :
"An unhandled exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll
Additional information: Conversion from string "" to type 'Double' is not valid."
Heres the part of the code.
