+---- Thread: [.NET] Program FUD if compiled in Visual Studio but 11/59 if compile via codedom. (/showthread.php?tid=4722922)
Program FUD if compiled in Visual Studio but 11/59 if compile via codedom. - SIM-2071734 - Mar 9, 2015
As the title says my program is FUD if I compile it via visual studio but if I compile via codedom the detections jumps from 0 to 11. Some shitty AVs detect my file as a Gen:Heur.MSIL.Agent.17. I'm using the same icon and assembly infos for both executables. The code is also the same.

I think it's due to the codedom code, since it's used commonly it'll detect it as fishy.

I tried to decompile my executables (codedom e non codedom) and looks like that codedom does not add resources and similar things. I need a obufuscator that can obuscate the .vb file... maybe this will solve my problem.

Ah yes, it seems like you have no idea what you are talking about.
When compiling with VS it adds other flags as well as compiler options when compiling. CodeDom doesn't. You need to specify them yourself.

Can you help me whit this? This is my codedom compiler:
Code
Public Sub Compile(ByVal Output As String, ByVal Source As String, ByVal DotNet2 As Boolean)
On Error Resume Next
Dim Compiler As ICodeCompiler = (New VBCodeProvider).CreateCompiler()
Dim Parameters As New CompilerParameters()
Dim cResults As CompilerResults
Parameters.GenerateExecutable = True
Parameters.OutputAssembly = Output
Parameters.ReferencedAssemblies.Add("System.dll")
Parameters.ReferencedAssemblies.Add("System.Data.dll")
Parameters.ReferencedAssemblies.Add("System.Windows.Forms.dll")
Parameters.CompilerOptions &= " /target:winexe /win32icon:" & ICO
Dim Version = New Dictionary(Of String, String)
If DotNet2 = True Then
Version.Add("CompilerVersion", "v2.0")
Else
Version.Add("CompilerVersion", "v4.0")
End If
cResults = Compiler.CompileAssemblyFromSource(Parameters, Stub)
If cResults.Errors.Count > 0 Then
For Each CompilerError In cResults.Errors
Console.BackgroundColor = ConsoleColor.White
Console.ForegroundColor = ConsoleColor.Red
Console.WriteLine(CompilerError.ErrorText)
Next
ElseIf cResults.Errors.Count = 0 Then
End If
End Sub
End Module* - taktaktak - Mar 9, 2015

Ah yes there's your problem right there, "On Error Resume Next". Remove it and never use it again, also helps if you dont C&P code :D
* - SIM-2071734 - Mar 9, 2015
I'm not copying anything... why I should remove "On Error Resume Next"? It's for debug propouses... sometimes I rename the icon, in this way the compiler does not crash.

If that's all you're using it for then why not use a Try Catch and display the exception so you can actually see whats going wrong?
* - SIM-2071734 - Mar 10, 2015
OK now i'm using Try(s) to preventiva crashes. BTW can someone help me or send me a tutoral/mdsn wiki page whit all the flagas/options forma codedom?
I'm on my phone atm

All you need to know is available here :

You must click on the links and read the contents ... we unfortunately can't do it for you....
The first step in the development of a project is to read resources before coding ;)

Visual studio also compiles with vbc.exe. So, the question you must ask yourself is what are the differences in my file compiled in the IDE and with codedom and how do I find them. If you decompile both apps using a combination of Reflector and Ildasm and the compare utility for notepad++ you should be able to find all the differences between your 2 files, then figure out how to make codedom compile with the same settings.
This will probably take you a few hours but you will learn a lot and you can create a nice dynamic generation of your binary without the issues you are having.
