I created an empty Visual Studio Solution called Solution.sln which I load into the workspace int the first line. Then I add a project to the solution, and update the workspace to the latest solution which should now contain a project. How do I write out the files for the new stuff I added to the empty solution?
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Roslyn.Compilers;
using Roslyn.Compilers.CSharp;
using Roslyn.Services;
namespace RoslynMainApp
{
class Program
{
static void Main(string[] args)
{
IWorkspace workspace = Workspace.LoadSolution(#"C:\RoslynSolutions\Solution.sln");
ProjectId projectId;
ISolution solution = Solution.Create(SolutionId.CreateNewId("Solution"));
solution.AddCSharpProject("Project1.dll", "Project1", out projectId);
var success = workspace.ApplyChanges(workspace.CurrentSolution, solution);
if(success)
{
//How do I write out all the stuff I just added to Solution.sln to the directory RoslynSolutions?
}
}
}
}
Thanks in advance,
Bob
The act of calling ApplyChanges should write the changes to disk. However, note that in CTP1, only a small set of the changes you can apply to solutions are actually implemented.

I am using the following code to find the length of a video file.
WindowsMediaPlayer windowsMediaPlayer = new WindowsMediaPlayer();
WindowsMediaPlayer player = windowsMediaPlayer;
var clip = player.newMedia(strPath);
WMPLength = $"{TimeSpan.FromSeconds(clip.duration)} ";
player.close();
The code returns what I expect but there are two problems.
One it crashes randomly. It crashes like its out of memory but while I do see memory usage go up it doesn't appear to be enough to crash the program
Two it is very slow
Am I missing something in cleaning up the code, a memory leak
or is there a better way to do this?
Thank you
First thing first: your method requires WMP installed on the computer, there are many editions without WMP installed oob.
This is an approach i am using and no problems so far (not sure why you need the media player) is it a specific requirement, extension ?
1-Install the following NuGet package, Microsoft.WindowsAPICodePack-Shell
https://www.nuget.org/packages/Microsoft.WindowsAPICodePack-Shell
2-Use the code snipet
using Microsoft.WindowsAPICodePack.Shell;
using Microsoft.WindowsAPICodePack.Shell.PropertySystem;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace VideoLenght
{
internal class Program
{
static void Main(string[] args)
{
Console.WriteLine(GetVideoDuration(#"C:\videos\20190531_005611.mp4"));
Console.ReadLine();
}
public static TimeSpan GetVideoDuration(string filePath)
{
using (var shell = ShellObject.FromParsingName(filePath))
{
IShellProperty prop = shell.Properties.System.Media.Duration;
var t = (ulong)prop.ValueAsObject;
return TimeSpan.FromTicks((long)t);
}
}
}
}
I am trying to access the macros inside of an Access database (accdb).
I tried using:
using Microsoft.Office.Interop.Access.Dao;
...
DBEngine dbe = new DBEngine();
Database ac = dbe.OpenDatabase(fileName);
I found a container["Scripts"] that had a document["Macro1"] which is my target. I am struggling to access the contents of the document. I also question if the Microsoft.Office.Interop.Access.Dao is the best reference for what I am trying to achieve.
What is the best way to view the content of the macros and modules?
You can skip the DAO part, it's not needed in this case. Macros are project specific, so in order to get them all, you would need to loop through your projects. In my example, i just have one project.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Office.Interop.Access;
namespace Sandbox48
{
public class Program
{
public static void Main(string[] args)
{
Microsoft.Office.Interop.Access.Application oAccess = null;
string savePath = #"C:\macros\";
oAccess = new Microsoft.Office.Interop.Access.Application();
// Open a database in exclusive mode:
oAccess.OpenCurrentDatabase(
#"", //filepath
true //Exclusive
);
var allMacros = oAccess.CurrentProject.AllMacros;
foreach(var macro in allMacros)
{
var fullMacro = (AccessObject)macro;
Console.WriteLine(fullMacro.Name);
oAccess.SaveAsText(AcObjectType.acMacro, fullMacro.FullName, $"{savePath}{ fullMacro.Name}.txt");
}
Console.Read();
}
}
}
I am trying to create script for my terminal server, which will move all folders with their contents, created in the wrong place. I don't know which names these folders will have. As I noticed, moving folders in C# is a problem for some reason. Can someone help me with my code? It just deleting my test folders and nothing moves.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
using Microsoft.VisualBasic.FileIO;
namespace ConsoleApp1
{
public class Programm
{
public static void Main()
{
string root = #"C:\Users\user1\Desktop";
string[] subdirectoryEntries = Directory.GetDirectories(root);
string destDirname = #"D:\confiscated";
foreach (string path in subdirectoryEntries)
{
FileSystem.MoveDirectory(path, destDirname, true);
}
}
}
}
This is how to do it:
string startPath = #"YOURSTARTPATH";
string endPath = #"YOURENDPATH";
foreach (string directory in Directory.GetDirectories(startPath))
{
Directory.Move(directory, Path.Combine(endPath, Path.GetFileName(directory)));
}
This way, you will use the already provided by the framework classes to work with directories.
No need to include Microsoft.VisualBasic.FileIO
I have couple questions about referencing methods / variables between two or more *.cs files. I know that there are similar topics, but I still don't quite understand what is going on.
I'm using Visual Studio Community 2015.
So here is the problem. I have 2 files, those files are First.cs and Second.cs. They are saved in completely different, known locations on hard disc.
Inside First.cs file:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Forum
{
class First
{
static void Main(string[] args)
{
}
public int GiveMeNumber()
{
return 5;
}
}
}
Inside Second.cs file:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Forum
{
class Second
{
int number = // method from file First.cs
}
}
How do I access method GiveMeNumber() from First.cs in Second.cs as assignment for int number? How do I tell my compiler where are those files?
Thanks for any help :)
Like Alex said in his comment.
You can create a solution/project, add existing item, and browse to your first.cs and second.cs.
Mark both files with the public-keyword
for example:
namespace Forum
{
public class Second
{
int number = // method from file First.cs
}
}
Then both class can be used within each other.
So you could do
var first = new First();
var number = first.GiveMeNumber();
you probably want to do it the other way around, because I think you have a console app where your First class has a main-method.
does that help>?
I've been played with Python.Net for a week, but I can't find any sample code to use Python.Net in embedded way although Python.Net source has several embeddeding tests. I've searched many threads from the previous emailing list (Python.Net), the results are not consistent and are clueless.
What I'm trying to do is to get result (PyObject po) from C# code after executing python command such as 'print 2+3' from python prompt via Python.Net because IronPython doesn't have compatibility with the module that I currently using.
When I executed it from nPython.exe, it prints out 5 as I expected. However, when I run this code from embedded way from C#. it returns 'null' always. Would you give me some thoughts how I can get the execution result?
Thank you,
Spark.
Enviroments:
1. Windows 2008 R2, .Net 4.0. Compiled Python.Net with Python27, UCS2 at VS2012
2. nPython.exe works fine to run 'print 2+3'
using NUnit.Framework;
using Python.Runtime;
namespace CommonTest
{
[TestFixture]
public class PythonTests
{
public PythonTests()
{
}
[Test]
public void CommonPythonTests()
{
PythonEngine.Initialize();
IntPtr gs = PythonEngine.AcquireLock();
PyObject po = PythonEngine.RunString("print 2+3");
PythonEngine.ReleaseLock(gs);
PythonEngine.Shutdown();
}
}
}
It seems like PythonEngine.RunString() doesn't work. Instead, PythonEngine.RunSimpleString() works fine.

IntPtr pythonLock = PythonEngine.AcquireLock();
var mod = Python.Runtime.PythonEngine.ImportModule("os.path");
var ret = mod.InvokeMethod("join", new Python.Runtime.PyString("my"), new Python.Runtime.PyString("path"));
Console.WriteLine(mod);
Console.WriteLine(ret);
PythonEngine.RunSimpleString("import os.path\n");
PythonEngine.RunSimpleString("p = os.path.join(\"other\",\"path\")\n");
PythonEngine.RunSimpleString("print p\n");
PythonEngine.RunSimpleString("print 3+2");
PythonEngine.RunSimpleString("execfile('" + external_file + "')");
PythonEngine.ReleaseLock(pythonLock);
PythonEngine.Shutdown();
}
}
