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 :)

Very basic knowledge on c# and is the first i use anything p/invoke related.
Help me pls, i have made this code but it doesnt seem to work.
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.Runtime.InteropServices;
namespace WindowsFormsApplication3
{
public partial class Form1 : Form
{
[DllImport("C:\\Users\\lchris\\Desktop\\SevenZipLib_9.13.2\\SevenZipLib\\SevenZipLib\\7z86.dll")]
public static extern void SevenZipArchive(string c);
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
using (SevenZipArchive archive = new SevenZipArchive("file.rar"))
{
foreach (ArchiveEntry entry in archive)
{
Console.WriteLine(entry.FileName);
}
}
}
}
}
It tells me that SevenZipArchive is a 'Method' and is being used like a 'type'.
I have include the library to my project already, i just dont know how to use it.
Here is the library:
https://sevenziplib.codeplex.com/
You first need to remove this code:
[DllImport("...")]
public static extern void SevenZipArchive(string c);
You do not need to provide any p/invoke declarations. The library wraps that up for you.
This is a .net assembly. You use it just as you use any other. Take the following steps:
Download the project. You already did that I think.
Build the solution. Make sure that
In your project, add a reference to the assembly that you built in the previous stage. It's SevenZipLib\bin\Debug\SevenZipLib.dll or SevenZipLib\bin\Release\SevenZipLib.dll depending on the target you selected.
Add using SevenZipLib; to your project code to to gain access to the namespace.
Once you've done that your code will work. You can use the tests project that is supplied as part of the download as a rich source of example code.
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.
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 :)
I trying to get my GPS position from a Desktop app, using Windows Runtime, in C#.
I followed this how-to to set up Visual Studio and this code sample to create the following trivial code as a C# console app :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using System.IO;
using System.Runtime;
using System.Windows;
using Windows;
using Windows.Devices.Geolocation;
using Windows.Foundation;
using Windows.Foundation.Collections;
namespace GeoLocCS
{
public sealed partial class Program
{
static void Main(string[] args)
{
Test test = new Test();
Console.Read();
}
}
public class Test
{
private Geolocator geolocator;
public Test()
{
Console.WriteLine("test");
geolocator = new Geolocator();
this.getPos();
}
async void getPos()
{
Geoposition pos = await geolocator.GetGeopositionAsync();
Console.WriteLine(pos.Coordinate.Latitude.ToString());
}
}
}
When trying to compile, I get the error :
Error 1 'await' requires that the type 'Windows.Foundation.IAsyncOperation<Windows.Devices.Geolocation.Geoposition>' have a suitable GetAwaiter method. Are you missing a using directive for 'System'?
I tried to reference every DLL that I could, like "System.runtime", "System.Runtime.WindowsRuntime", "Windows.Foundation"...
What I am missing ?
Thanks for the answer,
Serge
I finally figured out my problem :
I am on 8.1 so I changed this in the .csproj file (targetingPlatform) instead of targeting 8.0
After that modification, I could reference "Windows"
I manually referenced the two following DLLs :
C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.5\Facades\System.Runtime.dll
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\System.Runtime.WindowsRuntime.dll
If you are On Win8.1 Please Use:
<TargetPlatformVersion>8.1</TargetPlatformVersion>
and not 8.0.
Adding to the existing answers:
I suddenly got this problem with a multiproject solution in WPF (still don't know why). I tried switching between TargetPlatformVersions 8.1 and 10.0, tried using the v4.5- and v4.5.1-System.Runtime.WindowsRuntime.dll, always alternating between BadImageFormatException and FileNotFoundException.
Turned out to be references in some of the app.config-files (not the .csproj-files!). Visual Studio 2017 must have added them at some point and as soon as I removed these entries, the above solutions finally worked.
I was working through the MSDN tutorial for Crystal Reports, and I get to the Binding the Embedded Report to the CrystalReportViewer Control step:
When I try the build, it tells me that I am missing my using declaration for Hierarchical_Grouping class. This brings up two questions for me...
What is the namespace for this class definition?
Is there an easy way of determining the namespace of a given class?
In another answer I saw the 'ALT, SHIFT, F10' and the 'CTRL, [period]' suggestions for intellisense, but they don't work in my Visual Studio.
I'm sure I have done something ridiculously stupid....sorry in advance....
Here's the code for the form:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;
namespace CrystalTest3
{
public partial class Form1 : Form
{
private Hierarchical_Grouping hierarchicalGroupingReport;
public Form1()
{
InitializeComponent();
}
private void ConfigureCrystalReports()
{
hierarchicalGroupingReport = new Hierarchical_Grouping();
crystalReportViewer.ReportSource = hierarchicalGroupingReport;
}
private void Form1_Load(object sender, EventArgs e)
{
ConfigureCrystalReports();
}
}
}
I am assuming that you are referring to this tutorial.
The Hierarchical_Grouping seems to refer to the report file - which will contain the class named Hierarchical_Grouping. Have you added the report to your project?
The report should be somewhere in these Sample Reports Directories.
