Linking between c# and c++ in 64 bit machine

I have written a code in c++ and c# . From my c++ code i am calling my c# function through. I have sent just a part of c++ code.
txtPath contains the location of a text file.
C++ code:
CoInitialize(NULL);
IMyClassPtr obj3;
obj3.CreateInstance(__uuidof(Program));
obj3->Validation(txtPath);
CoUninitialize();
Validation() is my c# function.
My c# code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Diagnostics;
using System.IO;
using word = Microsoft.Office.Interop.Word;
using System.Runtime.InteropServices;
using System.Windows.Forms;
namespace ABC
{
[ComVisible(true)]
public interface IMyClass
{
void Validation(string txtp);
}
[ComVisible(true)]
[ClassInterface(ClassInterfaceType.None)]
public class Program : IMyClass
{
private string replace_string(string text)
{
return text.Replace("\r\a", "");
}
public void Validation(string txtp)
{
string[] textValidate = File.ReadAllLines(txtp);
string textpath = txtp;
//validation starts here
foreach (string line in textValidate)
{
string[] strsplit = line.Split(new string[] { "," }, StringSplitOptions.None);
string task = strsplit[0];
string sign = strsplit[1];
string person = strsplit[2];
string routing = strsplit[3];
if (String.IsNullOrEmpty(task) || String.IsNullOrEmpty(sign) || String.IsNullOrEmpty(person))
{
//if the txt file is invalid
MessageBox.Show("Signature.txt is incomplete or has invalid input!!!");
}
}
}
}
}
I have done all the required setting in c# .C# settings snapshot C# project is a class library. My code was working perfectly in 32 bit machine. I was using the generated tlb in other systems by registering it with regasm.exe.
In 64 bit machine by c++ code is working but when the c# linking code is hit the execution stops without throwing any error. I am using a 64 bit machine and created a new project with the same code. Help Please

Make you're using the correct version of 'regasm.exe' for your target platform (i.e. "C:\Windows\Microsoft.NET\Framework64\v2.0.50727\RegAsm.exe"). Take note of 'Framework64'.

On 64-bit Windows, Microsoft does not support loading a 64-bit DLL into a 32-bit process, or vice-versa. For additional information, please refer to the following resource on MSDN:

Telerik WinForm problems in Windows Server 2008 R2

I build wcf ,and it run's on Windows Server 2008 R2.Now i updated my program , and add Scheduler(telerik).
After this my aplication is start's to crash.
Do any one know how to fix it?
Here my code that works
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.IO;
using System.Linq;
using System.ServiceModel;
using System.Threading;
using System.Windows.Forms;
namespace WindowsFormsApplication
{
static class Program
{
// public static SchedulerForm Scheduler = new SchedulerForm(); here Scheduler disabled
private static NotifyIcon trayIcon;
static void Main()
{
using (ServiceHost host = new ServiceHost(typeof(SimpleService.SimpleService)))
{
host.Open();
SysTrayApp();
Application.Run();
}
}
public static void SysTrayApp()
{
/* tmNowActions = new ContextMenu();
tmNowActions.MenuItems.Add("....
my other function (not important)
*/
// Scheduler.ShowDialog();
}
}
}
And here after i remove comments and enable scheduler
namespace WindowsFormsApplication
{
static class Program
{
public static SchedulerForm Scheduler = new SchedulerForm();
private static NotifyIcon trayIcon;
static void Main()
{
using (ServiceHost host = new ServiceHost(typeof(SimpleService.SimpleService)))
{
host.Open();
SysTrayApp();
Application.Run();
}
}
public static void SysTrayApp()
{
/* tmNowActions = new ContextMenu();
tmNowActions.MenuItems.Add("....
my other function (not important)
*/
Scheduler.ShowDialog();
}
}
}
After this my aplication is crashed
Here the image from win server 2008 R2
Do any one know how to fix it?
UPDATE
I found that i was missing some telerik dll's,after i add them i get a new error.
If i will make empty WinForm all works fine,and i will see empty form ,but if i add telerik element(Scheduler in my case),i will get this error
Here another error that says i am missing Scheduler version,but you can see the dll and properties of this dll,and it is there it is not missing.

I resolved this problem like this:
1:Clean project and delete old files from Degub/bin.
2:Make sure all telerik dll's have the same version(end's .20 or .40) !!IMPORTANT!!.
3:In Telerik dll's click properties, and then make Copy Local = true !!IMPORTANT!!.
4:Rebuild the project.
After all this steps all start to work.

Running Python Script/application in Windows Phone 8

I want to run the Skeinforge slicer program written in Python inside my Windows Phone 8 C# application. I have determined that I should probably use IronPython to do this, I have already determined that I can run Skeinforge inside the ipy.exe terminal I got when I installed IronPython. My problem though is that I am struggling to figure out how to host and run a Python script with IronPython inside Windows Phone 8. I have also already managed to get a simple hello world script running inside a Desktop Windows Forms application that transfers the applications console output to the Debug console with the following code:
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 System.Diagnostics;
using System.IO;
using IronPython.Hosting;
using Microsoft.Scripting.Hosting;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
DebugWriter debugW = new DebugWriter();
Console.SetOut(debugW);
}
private void button1_Click(object sender, EventArgs e)
{
TextWriter tw = new StreamWriter("Test.py");
tw.Write(scriptBox.Text);
tw.Close();
try
{
var ipy = Python.CreateRuntime();
dynamic test = ipy.UseFile("Test.py");
}
catch (Exception ex)
{
Debug.WriteLine("Error: " + ex.Message);
}
}
}
}
And this is the DebugWriter:
class DebugWriter : TextWriter
{
private StringBuilder content = new StringBuilder();
public DebugWriter()
{
Debug.WriteLine("Writing console to debug");
}
public override void Write(char value)
{
base.Write(value);
if (value == '\n')
{
Debug.WriteLine(content.ToString());
content = new StringBuilder();
}
else
{
content.Append(value);
}
}
public override Encoding Encoding
{
get { return System.Text.Encoding.UTF8; }
}
}
I have no idea how to even add the IronPython libraries to my Windows Phone 8 application though as the standard libraries won't import. I have though tried compiling the apparently now defunct Windows Phone 7 libraries with the master source code and I can import these libraries, but I get absolutely no response on the debug terminal when I try to run my hello world script.
Do any of you have any idea how to get this woring in Windows Phone 8, if you know how to do this in Windows 8/Metro/RT then that would also probably work for WP8.
UPDATE:
I have looked at the debug output again and I seem to get this error when trying to use the WP7 libraries to run a hello world script:
A first chance exception of type 'System.NotImplementedException' occurred in Microsoft.Scripting.DLL
Error: The method or operation is not implemented.

I managed to get Skeinforge running on a modified version of IPY. You can get the source for my application here: http://skeinforgewp8.codeplex.com/

How to Call VSTS Coded Ui Scripts to QTP?

I am trying to execute my Coded UI Scripts on QTP.
First I created a dll for my Coded UI Project later I am able to access the methods from that dll but i am not able to access Coded UI testing methods.
Example:
the below script is in C# in VSTS
namespace TestProject1
{
using System;
using System.Collections.Generic;
using System.Drawing;
using System.Windows.Input;
using System.Windows.Forms;
using System.CodeDom.Compiler;
using System.Text.RegularExpressions;
using Microsoft.VisualStudio.TestTools.UITest.Extension;
using Microsoft.VisualStudio.TestTools.UITesting;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using Keyboard = Microsoft.VisualStudio.TestTools.UITesting.Keyboard;
using Mouse = Microsoft.VisualStudio.TestTools.UITesting.Mouse;
using MouseButtons = System.Windows.Forms.MouseButtons;
using Microsoft.VisualStudio.TestTools.UITesting.WinControls;
using Microsoft.VisualStudio.TestTools.UITesting.HtmlControls;
using Microsoft.VisualStudio.TestTools.UITesting.WpfControls;
public partial class UIMap
{
public int MyInteger()
{
return 9;
}
public string testDll()
{
return "Test DLL Factory";
}
public void add1()
{
MessageBox.Show("Sravan");
}
public void DeletePhoto()
{
WinWindow window = new WinWindow();
window.SearchProperties[WinWindow.PropertyNames.Name] = "Cyramed";
window.SearchProperties.Add(new PropertyExpression(WinWindow.PropertyNames.ClassName, "WindowsForms10.Window", PropertyExpressionOperator.Contains));
WinWindow c_window = new WinWindow(window);
c_window.SearchProperties[WinWindow.PropertyNames.ControlName] = "PICTUREBOX1";
c_window.WindowTitles.Add("Cyramed");
c_window.DrawHighlight();
WinClient c_client = new WinClient(c_window);
c_client.WindowTitles.Add("Cyramed");
c_client.DrawHighlight();
Mouse.Click(c_client, MouseButtons.Right);
Keyboard.SendKeys("{DOWN}");
Keyboard.SendKeys("{DOWN}");
Keyboard.SendKeys("{DOWN}");
Keyboard.SendKeys("{ENTER}");
}
}
}
I can call MyInteger and testDll methods but when I call the DeletePhoto method it throws an error: "Could not load file or assembly 'Microsoft.VisualStudio.TestTools.UITesting, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified."
My primary concern: I want to execute Coded UI scripts on QTP too.

You'll likely have to install Visual Studio Test Agents on your QTP test agents. These will drop the binaries on the machine.
VS 2010 Test Agents
VS 2010 SP1

JavaScript and C# Interpolation using Microsoft.JScript

How can I add a C# object to JavaScript code?
using System;
using System.Collections.Generic;
using System.Text;
using System.CodeDom.Compiler;
using System.Reflection;
using Microsoft.JScript;
using Microsoft.JScript.Vsa;
using Microsoft.Vsa;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
Program program = new Program();
program.Run();
}
public object Run()
{
VsaEngine Engine = VsaEngine.CreateEngine();
object Result = null;
try
{
//Engine.PushScriptObject(new ScriptObject());
// C# object replace with ?
Result = Eval.JScriptEvaluate("var a = 1; var b = c# object", Engine);
}
catch (Exception ex)
{
return ex.Message;
}
return Result;
}
}
}

Just compile your C# object into an assembly and load that assembly in your jscript code. all the languages that .NET supports can load each other's assemblies.

You can take a look at Script#
As they say,
"Script# brings the power and productivity of C# and .NET tools to Ajax development by compiling C# source code into regular JavaScript."
