The system assembly would already be in the references, if you created the project using VS. Are you mixing .NET framework versions?

What .NET version is the DLL targetting that you created?

Ok, I understand your point. The dll was targetting .net v2.0 and the program .net v4.6.1

I rebuilt the dll targetting .net v4.6.1

Still the same issue after restarting the Visual studio.

The type 'System.ComponentModel.IComponent' is defined in an assembly that is not referenced. You must add a reference to assembly 'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

The type 'System.ComponentModel.ISynchronizeInvoke' is defined in an assembly that is not referenced. You must add a reference to assembly 'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.	

The type 'System.ComponentModel.Component' is defined in an assembly that is not referenced. You must add a reference to assembly 'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

Any ideas?

Should work, might have problems if it was the other way around.

Only thing I can think of, is that you might be targetting the wrong CPU-type; if the DLL is compiled for 64 bits, and the app is targetting 32 bits, or the other way around.

Open up the csproj file in a text editor and look for this line:

XML

<Reference Include="System" />

If the line isn't there, include it alongside your other references.

Did you create a Console application by mistake? This is all setup for you already if you pick the Windows Forms Application project type.

Ok, created a new project for Windows form.

The recurring error now is:

Invalid token '(' in class, struct, or interface member declaration

In the code:

namespace Siren
{
    static class Program
    {
    public partial class Form1 : Form
    {
        IDictionary<string, Assembly> _libs = new Dictionary<string, Assembly>();

        // yada yada yada...

		int absW, absX, absY, absZ;
                
        // Your inputs here
        Console.Write("\nPlease input parameter 1 of first set... ");// Error occurs here...
        absW = Console.ReadLine();
     }
}
 static void Main()
 {
     Application.EnableVisualStyles();
     Application.SetCompatibleTextRenderingDefault(false);
     Application.Run(new Form1());
 }
}

The Console doesn't exist in a Windows Forms app.

Also, this looks like you're putting Console code into a Windows Forms project now, where before you where trying to use Windows Forms code in something other than a Windows Forms project.

So, which is it supposed to be? What are you really doing?

I'm being impatient because I expected to be done with this today. But since that is not going to happen, I'll stop cobbling things together and recode with fresh eyes tomorrow.
Thanks for the help.
Will get back to you.

Ehr.. stdout still exists in a WinForm. It is just a console-app that hides its console and puts up a GUI.

Hi,
I am converting a model into Xml format. That gives me xml in string. This string consists several \" character instead of ".

I need to remove all \ character from string. I tried remove by using replace method but it's not going. Is it possible to remove this character?

If yes, do a Debug.WriteLine, and you'll see that those characters aren't really there Smile | :)

"User Name" is not a normal column-name, and the space in the name will muck up the command. If that is how the column is actually named, you should add brackets like below;

where [User Name]=@user_name

..and complain loudly about the person who designed the database Smile | :)

Column names cannot contain spaces. Either rename your column to UserName, or wrap the column name in square brackets:

SQL

Select * FROM tbl_Loging where [User Name]=@user_name and Password=@password

However, you are currently storing your passwords in plain text. That is an extremely bad idea. You should only ever store a salted hash of the password, using a unique salt per record.

Storing passwords in clear text is a MASSIVE security risk.

No, the column-name was the problem. The extra brackets are the solution to that problem.

list subdirectories with specific names

Hi,
I have to get list of subdirectoris in parent folder ("A_ParentDir") which have names in format "vX.XX" where X is numeric.
Example : I have folder A_ParentDir which contains list of directories as below :
v3.20
v4.56
v8.1
v5.60a
v6.00v6.00

so I should have only :
v3.20
v4.56

I tried as below but I have also the last one in result
v3.20
v4.56
v6.00v6.00 // this shouldn't be

string strreg = @"v\d{1}\.{1}\d{2}$";

arrVersionsDirectories = Directory.GetDirectories(A_ParentDir)
.Where(path => Regex.IsMatch(path, strreg))
.ToList();

thank for help
