Working with embedded resources in external dll, without visual studios

Okay, so I've ran into a problem that I am having trouble finding a solution. There are plenty of solutions using visual studios properties. The issue is that I'm not using visual studios, I'm using csc.exe to compile my code.
Here's what I have so far.
exe.cmd
dll.cmd
Resource.dll
Main.csx
Rsc.csx
a.png
This is all of the code for the .cmd files and .csx files
exe.cmd
#echo off
csc.exe /target:winexe /reference:Resource.dll /out:Main.exe Main.csx
pause
dll.cmd
#echo off
csc.exe /target:library /resource:a.png /out:Resource.dll Rsc.csx
pause
Rsc.csx
using System;
using System.IO;
using System.Drawing;
using System.Reflection;
using System.Windows.Forms;
namespace EmIm
{
public static class Bck
{
public static Image GetBck()
{
Bitmap bmp = new Bitmap(Assembly.GetExecutingAssembly().GetManifestResourceStream("a.png"));
Image rtn = bmp;
return rtn;
}
}
}
Main.csx
using System;
using System.IO;
using System.Drawing;
using System.Reflection;
using System.Windows.Forms;
using EmIm;
namespace prg
{
class class_m
{
public static void Main()
{
Form f1 = new Form();
try
{
f1.BackgroundImage = Bck.GetBck();
}
catch(Exception e)
{
MessageBox.Show(e.Message);
}
f1.ShowDialog();
}
}
}
When I run this, I get a messagebox that displays value of 'null' is not valid for 'stream'
What steps do I need to take to be able to access a.png with reflection, I have checked to make sure a.png is the correct name in the assembly. Any help would be greatly appreciated. Thanks :)

A large thanks to Hans Passant for providing the simple solution to this problem. I had no idea even where to look to find out how to answer this problem, but he summed it up in a single comment.
only one file had to be altered in order for the program to work
new Rsc.csx file
using System;
using System.IO;
using System.Drawing;
using System.Reflection;
using System.Windows.Forms;
using System.Runtime.CompilerServices;
namespace EmIm
{
public static class Bck
{
[MethodImpl(MethodImplOptions.NoInlining)]
public static Image GetBck()
{
Bitmap bmp = new Bitmap(Assembly.GetExecutingAssembly().GetManifestResourceStream("a.png"));
Image rtn = bmp;
return rtn;
}
}
}
Once again, thanks Hans Passant for that quick fix to my problem, hopefully any other programmers stubborn enough to avoid Visual Studios could possibly look to this to find a solution that works without it. Have fun programming :)

Sikuli Integrator C#

I want to use SikuliIntegrator in C#.
I run VS as administrator, install SikuliIntegrator throught NuGet manager and want to test him on simple task.
Heres my code
using SikuliModule;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace SikuliTrainingNet
{
class Program
{
static void Main(string[] args)
{
string MyPicture = #"c:\111\Sik\MyPicture.png";
SikuliAction.Click(MyPicture);
}
}
}
after running code (and have prepared MyPicture on screen), all i get is exception "###FAILURE" any idea why?
I dont wanna use Sikuli4Net, becose its look like it work on web aps and I need just few simple clicks on desktop aplication.
I try sikuli in Java, and there it works with no problem. But I need to make my program in C#.

I Used This Code For Sikuli4Net in C#,It Was Working For Me First You need add the References please see this link for Reference
http://interviews.ga/angularjs/sikulic/
static void Main(string[] args)
{
APILauncher launch = new APILauncher(true);
Pattern image1 = new Pattern(#"C:\Users\Ramesh\Desktop\Images\userName.png");
Pattern image2 = new Pattern(#"C:\Users\Ramesh\Desktop\Images\password.png");
Pattern image3 = new Pattern(#"C:\Users\Ramesh\Desktop\Images\Login.png");
launch.Start();
IWebDriver driver = new ChromeDriver();
driver.Manage().Window.Maximize();
driver.Url = "http://gmail.com";
Screen scr = new Screen();
scr.Type(image1, "abc#gmail.com", KeyModifier.NONE);
scr.Type(image2, "12345", KeyModifier.NONE);
scr.Click(image3, true);
Console.ReadLine();
}

I used this code and it was working fine. First you should open the webpage on which you want to click and then give a path of the image(it should be a part of the webpage)
here is my code:
using System;
using System.Collections.Generic;
using System.Drawing;
using System.Linq;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using SikuliModule;
using OpenQA.Selenium;
namespace WordPressAutomation.DifferentTests
{
[TestClass]
public class Sikuli
{
[TestMethod]
public void TestMethod1()
{
driver.Initialize();
driver.instance.Navigate().GoToUrl("https://www.google.co.in");
SikuliAction.Click("E:/img.png");
}
}
}

To use SikuliInyegrator, you need to check the execution results in these files:
C:\SikuliExceptionLog.txt
C:\SikuliOutputLog.txt
Also you need to:
Have installed JRE7 or superior
Have environment variable PATH with the location of the bin folder
See installed in your “control panel > program and features> visual C++ 2010 Redistributable Package” at x86 and x64 bits according to your java JRE runtime platform. If not, then download and install the Redistributable Package form Microsoft site.

Creating Device in C# (Device not recognized as keyword)

I decided to try working with C# over c++ but ran into a problem.
The following code snippet shows the problem.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using Microsoft.DirectX;
using Microsoft.DirectX.Direct3D;
using System.Device;
namespace Project_AREA
{
public partial class Form1 : Form
{
private Device device;
public Form1()
{
InitializeComponent();
}
}
}
That's as much code as I have right now.
In private Device device;, the keyword Device is not getting recognized although all the libraries have been referenced and the using directives are included.
Any ideas?

Managed to Solve the problem.. for your reference and also if other run in to the same problem. You must add all the following references to the project: (note all files can be found on your had disk at c:\Windows\Microsoft.NET\DirectX for Managed Code) 1: Microsoft.DirectX.dll from folder 1.0.2902.0 2: Microsoft.DirectX.Direct3D.dll from folder 1.0.2902.0 3: MicrosoftMicrosoft.DirectX.Direct3DX.dll from folder 1.0.2911.0 Thanks for the help tho guys :)

how can I load values from App.config in c# using .Net Framework 4 Client Profile

I'm having difficulty getting my settings out of App.config. The research I've done so far says that I should be able to use ConfigurationManager.AppSettings (which is part of System.Configuration).
However, I can't get it to compile. And of course it doesn't like the older method (ConfigurationSettings.AppSettings) either as its obsolete.
What have I missed here?
Is it my project's Target Framework (currently set to ".Net Framework 4 Client Profile
")?
And example of my code follows:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Configuration;
namespace myNameSpace
{
class Program
{
private void LoadAppConfig()
{
string mySetting;
//This won't compile
mySetting =
System.Configuration.ConfigurationManager
.AppSettings["mySettingName"];
//This compiles but of course is obsolete, and I get that warning.
mySetting =
System.Configuration.ConfigurationSettings
.AppSettings["mySettingName"];
}
static void Main(string[] args)
{
// stuff happens
}
}
}

You need to add a reference to System.Configuration

cannot create instance of supersocketserver AppServer

I am trying to get the SuperSocketServer app up an running. However, I cannot seem to create an instance of the server. Here is my code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using SuperSocket.SocketBase;
using SuperSocket.SocketBase.Config;
using SuperSocket.SocketEngine;
using SuperSocket.SocketBase.Protocol;
namespace WinnieServer
{
class Program
{
AppServer W = new AppServer();
static void Main(string[] args)
{
Console.Write("Starting...");
while (true)
{
}
}
}
}
I tried the examples in the source code. However, they all give the same error:
Cannot create an instance of the abstract class or interface 'SuperSocket.SocketBase.AppServer'
Is this the correct way to create an instance of SSS?
take care,
lee

I had this same issue. The download on their home screen gives you the 1.4.4 version. If you look in object explorer it IS abstract. If you go to their downloads and grab the binaries zip, you'll get the 1.5 version that ISN'T abstract.
