C# - Decompiling .Net Assembly Produces Code With Invalid Member Variable Names; Names Starting With $STATIC$?

Sep 5, 2011

I am doing work for a client who has lost the source code for one of their VB.Net WinForms applications. The assembly they have is not obfuscated at all. I am trying to recover as much of the source as I can as C# source and have tried several tools for decompiling assemblies, including Reflector, ILSpy and JustDecompile (all the latest versions), but they all produce code with a huge number of errors in them. Because of the large number of errors in the generated code, I am going to ask about the specific errors (in different questions), get more directed answers and in this way try shed some light on why all the tools are having difficulty decompiling this assembly. This question pertains to the fact that the code generated by all these tools always have a large number of invalid member variables (fields) such as the following:

private short $STATIC$Report_Print$20211C1280B1$nHeight;
private ArrayList $STATIC$Report_Print$20211C1280B1$oColumnLefts;
private StaticLocalInitFlag $STATIC$Report_Print$20211C1280B1$oColumnLefts$Init;

why the generated code has these invalid member variables?

VS 2010 Variable Scope In Nested Classes?

Jul 13, 2011

I have put together the following code to illustrate the problems I've been struggling with:

Public Class OuterClass
Private _OuterProp1 As Boolean = False
Public Property OuterProp1 As Boolean

[code]....

I need to be able to refer to outer class properties and variables in an inner class, and I need to have a variable in one inner class set in a different class. I've tried Public, Private, Protected, Friend and all kinds of combinations of them, and I can't figure it out.

Create A Nested Loop With A Variable Amount Of Nests?

Aug 28, 2009

OK, after trying to get this working for a couple of days now I decided that I would turn to the experts here. I am trying to create a nested loop with a variable amount of nests. Let me elaborate. I have a program that first asks for the minimum and maximum amount of loops, I currently have a SELECT CASE statement that addresses each level of nesting individually.

Dim cMin As Integer = InputBox("Min")
Dim cMax As Integer = InputBox("Max")
Dim c1, c2, c3 As Integer

Asp.net - Update Linq To Sql With Variable Names?

Apr 15, 2012

im pretty much a beginner to using ASP.net and linq to sql but what im trying to do is update a column of a table based on a variable. at the momment i have

Dim db As New sqldcDataContext Dim update As tableName = (From i in db.tableNames _ Select i)

i think this selects everything, how could i have two variables, one to store what table to update and the other what column. is this possible?edit: sorry for being unclear im trying to make this as dynamic as possible so i dont have to type in the exact table/col names. something like this but in the linq to sql syntax.

mysql_query("SELECT * FROM ". $table ." WHERE `" . $column . "` = "" . $data ."");

Creating Variable Names From Other Variables?

May 20, 2010

how do I DIM a variable's name using previously declared string varialbes? I have been using PERL for processing data stored in text files but I now have a business need to use VB2008. I would like to do something like this:

dim name1 as string = "ABCD"
dim name2 as string = "123"

'here is the part that I don't know how to do - create a 3rd variable name concatenated from name1 and name2:

dim string.concat({name1,name2}), or maybe use a counter in a line like 'dim namex as string' with x being a counter value.

Essentially I want to dim variables using text strings extracted from a file. In PERL I have declared literals and arrays, such as 'my @$name1', which creates an array named with the contents of $name1. In VB2008 I am not sure how to make this work with the DIM statement.

Stripping Variable Names From Assemblies

Mar 29, 2010

I'm trying to reduce as much as I can my VB.Net assembly side, and I just figured out that all variable names were kept unchanged in the actual assembly. Since I tend to use pretty long var names, it adds up and, by running dotfuscator on my assembly, I could shrink it by as much as 10%.

Access Private Class Variable Names?

Jan 9, 2009

Trying to understand the best way to do this and I'm can't get it figured. Here's basically what I have:

Public Class CardParsingClass
Private iAcctIDStart as integer
Private iAcctIDLength as integer

[code]....

I've only included 2 of the class level fields here but there are actually 30, so that's why I was hoping to be able to send the name of the field to set and the value to set it at in the SetValue function. So in some other routine in the program I'd like to be able to issue the following call:

SetValue("iAcctIDStart", "3")

But then when I get into the SetValue routine, I'm not sure how to proceed. I thought about a case statement that would basically be this:

select Case strFieldToSet
case "iAcctIDStart"
iAcctIDStart = cint(strValue)

[code]....

Parse Variable Names And Operate From String?

Jun 10, 2011

I'm using a Microsoft Word form template to create objects in a form programatically, so depending on the information read by the program from the template.

So, I've got some fields where I store formula data for the form, in which I specify that the value for that field is obtained by multiplying other fields in the template. So I store in the string something like this:

"Text1.Text * Text2.Text"

So I need to convert these string values into variable calls to actually operate these values.

Repetition For List Of Settings With Unique Variable Names

Aug 12, 2011

this website seems great and this is my first post. Sorry if this has already been answered but I have been searching for a long time. I have a program with a list view in details mode. I have it load column settings (visibility, display index, width, etc.) when the form is opened and save them when closed. There are many columns...about ten so far...like folder, file, size, etc. Is there a way to access variable names from the values of other variables?

.net - Populating A List Box With Variable Names From LINQ Generated Class?

Nov 17, 2009

I'm quite new to Visual Basic - using Visual Studio 2008 and can't seem to find a way to do the following:

I have a few tables in a SQL Server database and have used LINQ to SQL to create classes of those tables.

Here's a cut down example of what I'd like:listbox1 filled with table names - APS, SMPS, WCPC, CFLAPS
Then from the SelectedIndexChanged event, listbox2 should populate column headers of the selected table.

I have no issues getting data from the database, and can access all of these headers through the anonymous type objects created from a LINQ query (eg APS.ID, APS.count etc), but populating a listbox with these variable names rather than the data inside them seems rather elusive.

This is probably a cross platform coding question rather than VB specific, so if you have a solution in C# or whatever I'd be happy if you could let me know.

Reflection - How To Get Variable Names Types / Values In Current Class

Feb 1, 2011

I am working on a project where my class has to execute VB code provided by the user, to make it simple I am trying to recreate my own eval function, I am using the following code I found on the web to do this task.

Imports Microsoft.VisualBasic
Imports System
Imports System.Text
Imports System.CodeDom.Compiler
Imports System.Reflection
[Code] .....

The problem with code is that it can't access any variables or there values, so I have decided to get the variable names, there values types and there types dynamically and recreate them in the class that is being created dynamically. Any way to get the variable names there types and values in the current class or method, so that I can recreate them, and execute the user passed code, the user knows what variables are in the current class or method and there datatypes but he don't know there values as they may have changed, so he can't initialize them. Is there a way to do this, this code will be called in an asp.net page on page_load event, the code passed by the user is stored in the variable vbCode that is passed as a parameter.

Visual Studio Upgrade Wizard Hates Some Of Variable Names

Aug 13, 2009

I am upgrading a VB6 to VB.NET project using the upgrade wizard.I know this is going to give me a lot of grief, but I am trying to make the old application useable. I'd rewrite it if I had time but am currently finishing up a summer internship and would like to get something working.One thing the wizard is doing that I can find no justification for is renaming of random variables. [code] For the life of me I don't understand why this is changing left. It isn't a reserved name as far as I can tell, there is no other variable named left that I can find in scope, and renaming it does not create a compiler error. [code] It does this to seemingly random variables throughout my project. Anyone have ideas as to why it doesn't like some of my variable names?

What i'm trying to do:

I've got a library which includes a class:

Class Human
End Class
and another class which refers to the human class

Class ASD
Private somevar as new Human
End Class

Ok now i've got a problem, i wish to rename my class Human, to Man. i've got to change Human to Man 2 times, which is OK but the problem is that in the real case, its not just 2 times, its like 500 times or more.

Well its something like a PHP on Javascript.

the following shows the solution of what i'm trying to do, but its in another language PHP/Javascript:

note: in php $ sign declares a variable, echo writes the variable out

ASP.NET VB Nested Listviews

Mar 29, 2011

I have an outer listview and inside its itemtemplate an inner listview. Each has its own SQLDataSource. A Id field from the outerlistview works as a select parameter for the second listview.

When stepping through with the debugger it works perfectly, unfortunately the rendered page only contains data from the outer listview. It appears the databinding of the outer listview fires and renders the page (including the inner listview) before the codebehind can provide a where parameter to the second listview. The aspx page is below.
