As you may know Windows Explorer allows to mount ISO files to a virtual drive.
Is there any API which can be used to do this?
The native function call AttachVirtualDisk.
However, if you are using C# like your tags suggest it may be easier to just call out to PowerShell and use its wrapper around that function Mount-DiskImage
using System.Management.Automation;
namespace IsoMountTest
{
internal class Program
{
private static void Main(string[] args)
{
var isoPath = #"C:\Foo\bar.iso";
using (var ps = PowerShell.Create())
{
ps.AddCommand("Mount-DiskImage").AddParameter("ImagePath", isoPath).Invoke();
}
}
}
}

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:
http://msdn.microsoft.com/en-us/library/aa384231(VS.85).aspx
after along time of searching via google, I decided to poste my problem here.
First: I am total C# Noob. I am using a Macro Recorder from Jitbit and I have no choice to use a different. The Problem is in the Macro Recorder, it is missing some essential things.
Like reading a text file into a variable and paste this variable via Clipboard :-(
However the good thing is, the tool support "some" type of native C# Code
If I open the C# Command I get this:
public class Program
{
public static void Main()
{
System.Windows.Forms.MessageBox.Show("test");
}
}
And the C# program has to follow also these rules:
=> This Code MUST contain a class named "Program" with a static method "Main"
I already used google and found code that should do the job but I get errors, I guess the
code doesn`t follow the above rules.
This is what I found and tried:
using System;
using System.IO;
public class Program
{
public static void Main()
{
// Read the file as one string.
System.IO.StreamReader myFile =
new System.IO.StreamReader("Counter.txt");
string counter = myFile.ReadToEnd();
myFile.Close();
// Load string into clipboard
Clipboard.SetDataObject( counter, true );
}
}
I always get the error : "Line 15: The Name Clipboard is not existing in the context"?!?
I hope that someone can explain a noob (me) what is wrong and what is the correct code.
Thanks.
add reference to System.Windows.Forms
using System;
using System.IO;
using System.Windows.Forms;
public class Program
{
[STAThread]
public static void Main()
{
Clipboard.SetDataObject(File.ReadAllText("Counter.txt"), true);
}
}
Note that to Avoid the ThreadStateException you need to applying the STAThread attribute to your Main() function
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/
I am using visual studio 2010 AddIn template for ArcGis 10.0. Since I already wrote a python code for ArcGIS processing. I would like to insert a button into the ArcMap desktop command bar running this python code. Following is my simplized c# code and the beginning of python code for your reference:
c# code:
using System;
using System.Windows.Forms;
using System.Collections.Generic;
using System.Text;
using System.IO;
using Microsoft.VisualBasic;
namespace CallPython
{
public class CallPython : ESRI.ArcGIS.Desktop.AddIns.Button
{
public CallPython()
{
}
public string inputName()
{
string inputNames;
inputNames = "cavert.shp";
return inputNames;
}
protected override void OnClick()
{
inputName();
System.Diagnostics.Process.Start(
"D:\\From2\\BCAP\\python\\scripts\\trans5.py");
}
protected override void OnUpdate()
{
Enabled = ArcMap.Application != null;
}
}
}
Python code:
import arcpy
import os, win32com.client
from arcpy import env
arcpy.env.overwriteOutput = True
# Set environment settings
env.workspace = "D:/BCAP/trans/tempt/"
# Set local variables
vs_method_source = os.path.abspath("D:/Users/mar/CallPython/CallPython.cs")
vs_file_name = os.path.abspath("D:/Users/mar/CallPython/CallPython.sln")
vs = win32com.client.Dispatch("VisualStudio.DTE.7.1")
doc_template = vs.Documents.Open(vs_file_name)
mm = doc_template.CallPython.inputName() #CallPython is namespace, inputName is method
The last line of python code is the problem. I know it is definitely not right, but didn't know how to access C# namespace, class, then method from python.
BACKGROUND
I am using Powershell 2.0 on Windows 7.
I am writing a cmdlet in a Powershell module ("module" is new to Powershell 2.0).
To test the cmdlet I am writing Unit tests in Visual Studio 2008 that programmatically invoke the cmdlet.
REFERENCE
This Article on MSDN called "How to Invoke a Cmdlet from Within a Cmdlet" shows how to call a cmdlet from C#.
THE SOURCE CODE
This is a distilled version of my actual code — I've made it as small as possible so that you can see the problem I am having clearly:
using System;
using System.Management.Automation;
namespace DemoCmdLet1
{
class Program
{
static void Main(string[] args)
{
var cmd = new GetColorsCommand();
foreach ( var i in cmd.Invoke<string>())
{
Console.WriteLine("- " + i );
}
}
}
[Cmdlet("Get", "Colors")]
public class GetColorsCommand : Cmdlet
{
protected override void ProcessRecord()
{
this.WriteObject("Hello");
this.WriteVerbose("World");
}
}
}
COMMENTS
I understand how to enable and capture verbose output from the Powershell command line; that's not the problem.
In this case I am programmatically invoking the cmdlet from C#.
Nothing I've found addresses my specific scenario. Some articles suggest I should implement my own PSHost, but seems expensive and also it seems like a have to call the cmdlet as text, which I would like to avoid because that is not as strongly typed.
UPDATE ON 2009-07-20
Here is is the source code based on the answer below.
Some things are still not clear to me:
* How to call the "Get-Colors" cmdlet (ideally without having to pass it as a string to the ps objet)
* How to get the verbose output as it is generated instead of getting an collection of them at the end.
using System;
using System.Management.Automation;
namespace DemoCmdLet1
{
class Program
{
static void Main(string[] args)
{
var ps = System.Management.Automation.PowerShell.Create();
ps.Commands.AddScript("$verbosepreference='continue'; write-verbose 42");
foreach ( var i in ps.Invoke<string>())
{
Console.WriteLine("normal output: {0}" , i );
}
foreach (var i in ps.Streams.Verbose)
{
Console.WriteLine("verbose output: {0}" , i);
}
}
}
[Cmdlet("Get", "Colors")]
public class GetColorsCommand : Cmdlet
{
protected override void ProcessRecord()
{
this.WriteObject("Red");
this.WriteVerbose("r");
this.WriteObject("Green");
this.WriteVerbose("g");
this.WriteObject("Blue");
this.WriteVerbose("b");
}
}
}
The code above generates this output:
d:\DemoCmdLet1\DemoCmdLet1>bin\Debug\DemoCmdLet1.exe
verbose output: 42
UPDATE ON 2010-01-16
by using the Powershell class (found in System.Management.Automation but only in the version of the assembly that comes with the powershell 2.0 SDK, not what comes out-of-the-box on Windows 7) I can programmatically call the cmdlet and get the verbose output. The remaining part is to actually add a custom cmdlet to that powershell instance - because that was my original goal - to unit test my cmdlets not those that come with powershell.
class Program
{
static void Main(string[] args)
{
var ps = System.Management.Automation.PowerShell.Create();
ps.AddCommand("Get-Process");
ps.AddParameter("Verbose");
ps.Streams.Verbose.DataAdded += Verbose_DataAdded;
foreach (PSObject result in ps.Invoke())
{
Console.WriteLine(
"output: {0,-24}{1}",
result.Members["ProcessName"].Value,
result.Members["Id"].Value);
}
Console.ReadKey();
}
static void Verbose_DataAdded(object sender, DataAddedEventArgs e)
{
Console.WriteLine( "verbose output: {0}", e.Index);
}
}
[Cmdlet("Get", "Colors")]
public class GetColorsCommand : Cmdlet
{
protected override void ProcessRecord()
{
this.WriteObject("Hello");
this.WriteVerbose("World");
}
}
Verbose output is not actually output unless $VerbosePreference is set at least to "Continue."
Use the PowerShell type to run your cmdlet, and read VerboseRecord instances from the Streams.Verbose propery
Example in powershell script:
ps> $ps = [powershell]::create()
ps> $ps.Commands.AddScript("`$verbosepreference='continue'; write-verbose 42")
ps> $ps.invoke()
ps> $ps.streams.verbose
Message InvocationInfo PipelineIterationInfo
------- -------------- ---------------------
42 System.Management.Automation.Invocat... {0, 0}
This should be easy to translate into C#.
1. string scriptFile = "Test.ps1";
2. using (PowerShell ps = PowerShell.Create())
3. {
4. const string getverbose = "$verbosepreference='continue'";
5. ps.AddScript(string.Format(getverbose));
6. ps.Invoke();
7. ps.Commands.Clear();
8. ps.AddScript(#".\" + scriptFile);
9. ps.Invoke();
10. foreach (var v in ps.Streams.Verbose)
11. {
12. Console.WriteLine(v.Message);
13. }
14. }
Important lines are line 5 and 6. This basically set the $verbosepreference for the session and for upcoming new commands and scripts.
First off, if you are unit testing cmdlets, likely Pester is a better (and easier) option.
As per your many updates, all you are likely missing at this point is a strongly typed approach to reference the C# cmdlet
ps.AddCommand(new CmdletInfo("Get-MyCS", typeof(GetMyCS)));
DISCLAIMER: I know this works for PowerShell 5.0, but don't have experience with the older PowerShell 2.0.
