Problem with running EXE from a byte() array
in [VB.NET]
|
From: sebastian nielsen on 3 Jul 2008 04:41 If I have this code: Dim fs As New System.IO.FileStream("C:\application.exe", System.IO.FileMode.Open) Dim br As New System.IO.BinaryReader(fs) Dim data() as Byte data = br.ReadBytes(Convert.ToInt32(fs.Length)) br.close() fs.close() Now data() contains the whole EXE in binary format, and I want to run the binary data like the C:\application.exe was executed. I tried with this: Dim oAss As System.Reflection.Assembly Dim meth As System.Reflection.MethodInfo Dim obj As Object oAss = System.Reflection.Assembly.Load(data) meth = oAss.EntryPoint obj = oAss.CreateInstance(meth.Name) meth.Invoke(obj, Nothing) but it stumbled on Load(data) that BadImageFormatException "It could not read the file or collection 77824 bytes loaded from WindowsApplication1, Version=1,0.0.0, Culture=neutral, PublicKeyToken=null or one of its dependencys. A attempt to read in a application with a invalid format was made" Then I tried with another EXE, but the it stumbled on the Invoke(obj, Nothing) that a incorrect number of parameters was supplied. The debugger said that obj was "nothing", so apparently the oAss.CreateInstance method failed. I want it to work with any EXE, and the application should run the content in the data() array like he EXE was launched itself. I don't want to write the EXE to disk and exec it with the Shell() method or some like that.

From: sebastian nielsen on 4 Jul 2008 05:16 Yes, but what im doing, is that I have a encoder application, which loads lets say c:\application.exe and makes a BASE64 string of it. Then I put that BASE64 string as a constant into my application, and now I want to run the BASE64 string by decoding it and then running the contents in memory without writing the EXE to disk. In other words, I want to hard-code a application into my application.

Sebastian, This is the difference between common people like most of us and artist like you. We just choose the most efficient methods, you see this probably as art. However, art has to be unique, so very much success with your creation.
