Question about multiple namespace

[Rob Stevens]

I am having a bit of a problem accessing some information in a different
namespace,
hopefully someone can point out what I am doing wrong.

I have a dll file that I dont want to use in my program, I just want to use
the functions
in my program. But after placing the class into my program, I can't seem to
get the
funcs to compile.

//------------------------------------------------------------------------------
namespace TextBox_Editor
{
public partial class frmMain : Form
{
public frmMain()
{
InitializeCompo nent();
}

// I want to access 'Settings' from below here in the main
// scope but the error states it does not kow what it is.
private void frmMain_Load(ob ject sender, EventArgs e)
{
TextBox1.Settin gs.Keywords.Add ("function") ;
}

namespace Highlighter
{
public class MyTextBox : System.Windows. Forms.TextBox
{
private mySettings m_settings = new mySettings();
private string strtrLine = "";

public SyntaxSettings Settings
{
get { return m_settings; }
}
}
}
}
}

What do I need to do here to get this to work?


TIA

Well, you haven't shown where or how TextBox1 is declared. Is it
declared to be a MyTextBox? Does that part work, barring access to
Settings?

I do not understand the above, if you are using the methods of the DLL you
are using the DLL

What errors are you getting?

I am not trying to use the DLL, I just want to use the functions from the
dll, but I want the
functions in my program and not an external dll file.

I am not really sure I understand. The RichTextBox (TextBox1) is in the
program, but settings does not exit as a property for RichTextBox.

private void frmMain_Load(ob ject sender, EventArgs e)
{
RichTextBox1.Se ttings.Keywords .Add("function" );
}

Since I am moving the functions from an external DLL file into my program, I
don't
know how to make the functions accessible even though everything is within
the
same scope (i think).

It sounds like you want a static function Settings contained in some class.
You cannot call a method on any random class. When the code was in a
different dll, how did you call the method Settings()? You weren't calling
it on a RichTextBox, right?

Yes it was calling the RichTextBox by its actual name.

// DLL File
using System;
using System.Collecti ons.Generic;
using System.Text;
using System.IO;
using System.Windows. Forms;
using System.Componen tModel;
using System.Text.Reg ularExpressions ;
using System.Drawing;

namespace SyntaxHighlight er
{
public class SyntaxRichTextB ox : System.Windows. Forms.RichTextB ox
{
private SyntaxSettings m_settings = new SyntaxSettings( );
private int m_nCurSelection = 0;

/// The settings.
public SyntaxSettings Settings
{
get { return m_settings; }
}
etc. etc.
}
}
// --------------------------------------------------
// Other file using the dll file
using System;
using System.Collecti ons.Generic;
using System.Componen tModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows. Forms;

namespace SyntaxTester
{
private void MainForm_Load(o bject sender, EventArgs e)
{
// Add the keywords to the list.
m_syntaxRichTex tBox.Settings.K eywords.Add("fu nction");
m_syntaxRichTex tBox.Settings.K eywords.Add("if ");

etc. etc.

I am noticing some more code in the MainForm.Design er.cs that I had not
noticed before.

private void InitializeCompo nent()
{
this.m_syntaxRi chTextBox = new
SyntaxHighlight er.SyntaxRichTe xtBox();
this.m_buttonQu it = new System.Windows. Forms.Button();


#endregion

private SyntaxHighlight er.SyntaxRichTe xtBox m_syntaxRichTex tBox;
private System.Windows. Forms.Button m_buttonQuit;


I am assuming that I have to put this code into my Form1.Designer. cs file
too?
This is pretty new to me, I would appreciate any hand holding here. I
always seem
to start with the tough stuff first.

Thanks

OK, so if you put the above class in your new project, you should be able to
create an instance of a SyntaxRichTextB ox , add it to a form, and call
Settings on any instance. You cannot creat an instance of a RichTextBox and
call Settings on that object however.

You will also need to bring SyntaxSettings class into the project.

Does this help, or am I missing your problem (quite possible!).

And what is the difference between both statements? "using a dll" is "using
the methods of the dll"

functions in my program and not an external dll file.

Do you mean that you want to embed the dll in your .EXE ?

It's hard to say - all the names keep changing in each post. First
there was frmMain, then Form1, then MainForm - and likewise there was
MyRichTextBox, then RichTextBox, then SyntaxRichTextB ox. That makes it
really hard to keep track of what you've *actually* got where.

Could you post a short but complete program which demonstrates the
problem?

See http://www.pobox.com/~skeet/csharp/complete.html for details of
what I mean by that.

Sorry about that, I have been posting from my pc and at a friends house.
I did get it to work, I just added in the information to the
Form1.Designer. cs
and it worked.

Well, that's a bit worrying - you should never need to touch the
designer files yourself, they're "owned" by the designer, and will be
recreated next time you change something in the designer.
