I have to projects in my solution: StoreHelper and DefaultsSwitcher. Both of them have to create a Windows Executable (their output is application).
Now we are located in StoreHelper. This is my code:
At the top of the file:
using DefaultsSwitcher;
And in the file:
private void defaultsSwitcherToolStripMenuItem_Click( object sender, EventArgs e ) {
var defaultsSwitcher = new DefaultsSwitcher.dialog();
defaultsSwitcher.ShowDialog();
}
The code editor does not show any error by underlining, but when I try to build, the compiler say the following error:
Error 1 The type or namespace name 'dialog' does not exist in the namespace 'DefaultsSwitcher' (are you missing an assembly reference?) E:\Apps\StoreHelper\StoreHelper\mainWindow.cs 84 25 StoreHelper
Which is the problem? P.S. I want these two projects to pe .exe files after building.
The code in DefaultsSwitcher:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using StoreHelperLib.Options;
namespace DefaultsSwitcher {
public class dialog : Form {
public dialog() {
var options = new iniHelper();
if (!File.Exists( "settings.ini" )) {
StreamWriter settings = new StreamWriter( "settings.ini" );
settings.Close();
}
options.Load( "settings.ini" );
options.AddSection( "Application" );
options.SetKeyValue( "Application", "firstRun", "true" );
options.SetKeyValue( "Application", "startGuide", "false" );
options.Save( "settings.ini" );
InitializeComponent();
}
}
}
Is there any communication between the apps, or are you just trying to start the one app from the other app? If the latter, use System.Diagnostics.Process and have Windows run the other EXE file seperately.
http://msdn.microsoft.com/en-us/library/system.diagnostics.process.aspx
This also means that you can have both apps be able to start the other because there would not be a circular dependency.
I think that you have miss to include the child Project to his parent.
To do this : Right clic on Reference folder in StoreHelper project and clic on Add Reference.
Finally choose DefaultsSwitcher project.
Now the DefaultsSwitcher namespace must be accesible from the StoreHelper project
I found a solution for my problem to keep both projects output to EXE. I have just to use:
public partial class dialog

So I've been stuck on this error for a good week now, and it has been very frustrating
(Impossible to load the file or assembly 'Audio.Default.Switcher.Wrapper.dll' or one of its dependencies. The specified module wasn't found)
I'm working with Visual Studio 2017 and I've downloaded the SoundSwitch project, and everything is working perfectly fine. I'm able to run "SoundSwitch" without any errors.
The way the solution works (as I'm able to understand) is that the "SoundSwitch" C# project is the "master" and it has references to "Audio.Default.Switcher.Wrapper" as well as "SoundSwitch.UI.UserControls"
"Audio.Default.Switcher.Wrapper" as a reference to "AudioDefaultSwitcher"
Both "Audio.Default.Switcher.Wrapper" and "AudioDefaultSwitcher" seem to compile as .dll files
"SoundSwitch.UI.UserControls" cannot be started and is used for display stuff I guess
"SoundSwitch" is the only startable project (not counting mine of course)
The K005_test is MY project, I've added it and it has references (only) to "SoundSwitch" and I'm trying to use the functions from the SoundSwitch project inside K005_test. And so far my K005_test project consists only of
Program.cs (where I get the error by the way)
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace K005_test
{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1()); //Exception thrown here
}
}
}
Form1.cs (where I put my code for the test)
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;
namespace K005_test
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
MessageBox.Show("This is a test");
var test = SoundSwitch.Model.AppModel.Instance.AvailablePlaybackDevices; //Error this line exists
}
}
}
And when I run my K005_test project, it compiles and runs just fine, except when I click the button Then I get the error I posted above. Also the message box doesn't open.
What I've tried so far :
Flipping everything to "x86" or "Win32", it seems that it might be related a problem with 64bit something
Using references to both "Audio.Default.Switcher.Wrapper.dll" and "SoundSwitch" in K005_test
copy "Audio.Default.Switcher.Wrapper.dll" pretty much everywhere and praying the gods
Trying to understand where it looks for "Audio.Default.Switcher.Wrapper.dll" but I wasn't able to find anything when looking in the exception details
Nothing has helped in any way.
For anybody wondering, I've uploaded my entire project folder here
https://drive.google.com/open?id=1OABjDiZyF0B-1-b15_9lzMrPZ4UpyKqU
I know that this question has been already asked, but I cannot find anything that can help solve my problem.
I want to connect my aspx page (Retete.aspx) to a Microsoft SQL database. I'm getting this error on Retete.aspx.cs:
Error 1 The type or namespace name 'GlobalClass' does not exist in the namespace 'ProiectSera' (are you missing an assembly reference?)
The error points to this line of code:
ProiectSera.GlobalClass.Update(ValRefTempSol.Text, ValRefTempAer.Text);
Where ProiectSera is the project name, GlobalClass is the file where I make the operation on the db.
My using statements are:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using ProiectSera;
The Target Framework is set to .net-4.5.
What should I do to solve this error?
Update
My GlobalClass.cs is:
using System;
using System.Data;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Data.SqlClient;
using System.IO;
using ProiectSera;
using System.Data.Services;
namespace ProiectSera.App_Code
{
public static class GlobalClass
{
static public void Update(string _param1, string _param2)
{//function to update}
}
}
App_Code is a folder where GlobalClass.cs is. I tried and
ProiectSera.App_Code.GlobalClass.Update(ValRefTempSol.Text, ValRefTempAer.Text); //
but I had the same error. And I put the GlobalClass.cs in the project's root. I also removed the .App_Code from namespace ProiectSera.App_Code
UPDATE1
My Retete.aspx.cs is
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using ProiectSera;
using ProiectSera.App_Code;
namespace ProiectSera
{
public partial class Retete : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnSave_Click(object sender, EventArgs e)
{
string intValRefTempSol;
string intValRefTempAer;
// intValRefTempSol = ValRefTempSol.Text;
// intValRefTempAer = ValRefTempAer.Text;
// ProiectSera.App_Code.GlobalClass.Update(ValRefTempSol.Text, ValRefTempAer.Text);
GlobalClass.Update(ValRefTempSol.Text, ValRefTempAer.Text);
}
}
}
Your GlobalClass is in the namespace ProiectSera.App_Code.
So the class name is ProiectSera.App_Code.GlobalClass
Make sure you don't have a ProiectSera class in the ProiectSera namespace also, otherwise if declaring using ProiectSera on top, it'll try to use it (as a general rule, don't name any class the same as your namespace).
If that still doesn't work, you may want to try using the global namespace:
global::ProiectSera.GlobalClass.Update(ValRefTempSol.Text, ValRefTempAer.Text);
and see if that works: if it doesn't, and GlobalClass is in the same project, then there's something else you haven't shown us
Update
The only other thing that comes to mind, if you are positive that both files are on the same project/assembly, is that GlobalClass.cs is not being actually compiled. Make sure the Build Action is set to Compile (you can see the build action right clicking on the GlobalClass.cs in the solution explorer and selecting Properties).
If you are using VS.NET:
Right click on the References folder on your project.
Select Add Reference.
Select the .NET tab (or select the Browse button if it is not a .NET Framework assembly).
Double-click the assembly containing the namespace in the error message.
Press the OK button.
Ensure the following...
That you have a project reference to ProiectSera from your web application, if it's in a separate library. If GlobalClass is in the web application project itself, you won't require this, but if GlobalClass is defined in a separate library in the same solution or elsewhere, then you're going to need to add a reference to that external library in your web application.
Ensure that ProiectSera should not be ProjectSera (if it's a typo).
Ensure that you have your ProiectSera using statement in place at the top (using ProiectSera;). Assuming that this is the correct namespace. Check the namespace of your GlobalClass class and use that using accordingly in the class that wishes to use its functionality.
Then, simply call this in your code, assuming that Update is a static method of GlobalClass.
GlobalClass.Update(ValRefTempSol.Text, ValRefTempAer.Text);
EDIT: given that you've now posted your GlobalClass code, you can see that the namespace for this class is ProiectSera.App_Code;. So you need to have that as your using statement in the other class using ProiectSera.App_Code;. And then call it via simply GlobalClass.Update, as mentioned above.
If you don't understand how namespacing works in C#, then I recommend you check this out (https://msdn.microsoft.com/en-us/library/dfb3cx8s.aspx).
I`ve seen some stackover flow on how to do this but i cant get it to work for myself in visual studio.
What is wrong with code? I have downloaded FFMpeg and im using it as reference. yet, I get the error
"Could not load file or assembly Aforge.Video.FFMPEG. dll or one of
its dependencies"
Here is the 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 AForge;
using AForge.Video;
using AForge.Video.FFMPEG;
namespace WindowsFormsApplication6
{
public partial class Form1 : Form
{
public Form1()

InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
// create instance of video reader
VideoFileReader reader = new VideoFileReader( );
// open video file
reader.Open( "test.avi" );
// read 100 video frames out of it
for ( int i = 0; i < 100; i++ )
{
Bitmap videoFrame = reader.ReadVideoFrame( );
videoFrame.Save(i + ".bmp");
// dispose the frame when it is no longer required
videoFrame.Dispose( );
}
reader.Close( );
}
}
}
The program stop when i click the button and comes with an error.
It looks like the dll might have been moved / deleted (or) probably not checked-in. Usually the best practice is to add them in a library folder (say lib or bin) within your project. So when you check-in your stuff, all the library files get checked in too, and your references are intact.
Since the dll seems to be external, I'm hoping you browsed to it and added the reference.
Can you copy the dll file (preferably within a lib folder) within your project and then add the reference again?
It looks like Visual Studio added the reference but it's not able to find the file.
I'm guessing doing this will solve your problem.
You may need to check the way you build your project as well. Some DLLs may only work under x86 or x64 build configuration. Maybe not the parent dll directly but the references it uses internally.
You need to add to your bin folder the dlls from AForge.NET\Framework\Externals\ffmpeg and make sure you're running 32 bit (project properties -> debug -> platform -> x86
I'm trying to add a reference to a project ("Geometry") that lives in another solution ("Bar Solution") into another solution ("Foo Solution"). Any project in Bar Solution (the home of the Geometry's source code) can import Geometry and use its features with no problem; however, when I add the DLL to Foo Solution, it imports fine, but the Object Browser shows it containing no namespaces or classes.
Has anyone experienced this problem or otherwise know of a solution? I can't find any information on SO or more generally, le Goog.

I have a c# problem. I have created a project called 'classproject' and I have added several forms to project successfully and successfully ran the program, but there is this other windows form that I just added and when I double-clicked on the form, it took me to the code view and brought out this:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class demo : Form
{
public demo()
{
InitializeComponent();
}
private void demo_Load(object sender, EventArgs e)
{
}
}
}
Now, my challenge is that the name of the project is meant to show by default after the namespace as in "namespace classproject" instead of "namespace WindowsFormsApplication1". Please can anyone help me out, what am I meant to do because have tried everything possible. Even if I change the name myself its still going to flag error... someone please help me as soon as possible.
I'm not sure exactly what your issue is. If you change the namespace manually in the code to classproject it should be fine. What error are you talking about? You would also need to change the designer code file as well (probably called demo.Designer.cs).
Just a side note as well. Standard naming convention for C# is to use Pascal-case (as in ClassProject).
You must change namespace in ALL files that was generated by Visual Studio. You can do it manually, or just set cursor on "WindowsFormsApplication1", press F2 and enter new name.
Optionaly you can also change namespace in project properties on Application tab - then all new files added to project will also have namespace that you set there.
