FileOpen dialog on indicator

[koganam]

Dear Buddy,

you need to add referrence to System.Design.dll file for this to complile. Depending on IDE you use this may vary... On Ninja editor just press right click and follow from there.

That there is the problem if one tries to distribute the indicator. Are we then to instruct the user how to add a reference? I have not seen any "Help" topic on how to add a new reference, when one adds an indicator, without using the right-click configuration dialog box. Suggesting that we write installation code to directly edit Config.xml, will cause a heart attack in the NT developers, so we do not even need to go there.

What about second part of my question - any ideas how to change description entry for particular plot? Any ideas how to hide plot style and color select dialog at all?
-Andrius.

The name that shows for the plot, is set directly when you define the plot in the Initialize() method, thus:

  
Add(new Plot(Color.Green, "[B]This is the name that shows in the configuration GUI[/B]"));

You hide the plot configuration dialog using this line in the Initialize() method:

PlotsConfigurable = false;

What is the right way to do this?

For my future reference, what is the easy way to do that (in the NT editor)?

• I presume you want just the DLL name so normal search rules are in effect.
• Entering the name in the "References... | Add..." dialog forces a fully qualified pathname -- I saw no way to avoid that
• I found a likely looking XML file (Config.xml) and edited that -- inserted between System.Core.dll and System.Drawing.dll, to preserve alphabetic order. (I can just see the NT support folks cringing ...)
• That worked, but only after stopping and restarting NT

I presume there is an easier way -- please enlighten me?

Depending on your coding skills it would be possible to add something like a WinForm to the property grid. Advantage still is that you are conform with the rules how NT sets up an indicator. Here is the link to an example illustrating how that could be reached:

Basically you're right. But In a WinForm, one could structure the input parameters a little bit better.

[Ralph]

Do you really want to stop the NT tool? Don't know if that's a good idea. Why don't you use the property grid for input? It is guaranteed to provide its content before the indicator starts operating.
If the property grid gets to confusing because you need to input a lot of date, then you could develop something with the expansion functionality of the grid (this little + - signs). Especially, if you have a lot of date with a repetitive structure you could use the property expansion quite effectively.

I have a similar problem.

I want to capture the input parameters for an indicator of a C # form. The call of the OnBarUpdate method should be avoided until the form is closed.

my idea is:

public class ParmsForm : Form
public ParmsForm ()
{
this.Text = "C# - einfaches Form";
this.Size = new Size(600, 400);

AddContextMenuAndItems();

addControls();

}
.... .... ....

I call the modal form from inside the OnStartup method:

protected override void OnStartUp()
{
ParmsForm parmsForm = new ParmsForm();
parmsForm.ShowDialog();
}

The form is displayed. However, the OnBarUpdate method is called before the form is closed. My parameters are thus in the indicator is still not known.

Does anyone provide any solution or idea?

The reason I didn't think it would work in 6.5 is because
// FileNameEditor

//Does not seem to be valid here

[Editor(typeof(System.Windows.Forms.Design.FileNameEditor),
typeof(System.Drawing.Design.UITypeEditor))]


Then I tried the same in NT7 and found the same thing

[andrius]

Dear Buddy,

the same code works for both NT6.5 and NT7. basically you override System.Windows.Forms.Design.FileNameEditor with something bukkan wrote.

What about second part of my question - any ideas how to change description entry for particular plot? Any ideas how to hide plot style and color select dialog at all?

Thank you,

[Buddy]

How about an equivilant for NT6.5? This would be nice!

ahh the pic made things clear. still its a c# thing and googling will help more rather than searching here.

heres a sample code

in the variable region

string open;

in properties

[Description("")]
        [GridCategory("Parameters")]
        [Editor(typeof(System.Windows.Forms.Design.FileNameEditor),
          typeof(System.Drawing.Design.UITypeEditor))]
        public string Open
        {
            get{return open;}
            set{open = value;}
        }

For some reason I can't download that JPEG to look at what you are trying to achieve.

Off the top of my head an enum with a switch statement, say, UserSound that calls the OpenFileDialog if selected should do the trick.

You might need to watch how you Dispose of things, though.

[andrius]

Dear bukkan,

I am aware about OpenFileDialog(); however I fail to understand how to fit it into Indicator's properties dialog under particular field. Please see screenshotted example what I am trying to achieve...

Thank you,
-Andrius.

[bukkan]

what you are asking is standard C# queries. google a bit and you will get the answer. anyway heres a nt code.

using System.Windows.Forms;

protected override void OnStartUp()
        {
            
            OpenFileDialog file = new OpenFileDialog();
            file.ShowDialog();
            
            string path;
            path = file.FileName;
            MessageBox.Show(path);
            
        }
