input file is selected

[stasha]

Dear NT support,
Can you please answer the following questions:

1. how can I make sure file parameter used as below does not left empty (actual file being selected), before closing the dialog:
2. how can i show error message box (MessageBox.Show does not work) to force user to select a file before she closes the dialog

[NinjaScriptProperty]
[PropertyEditor("NinjaTrader.Gui.Tools.FilePathPick er", Filter = "CSV Files (*.csv)|*.CSV")]
[Display(Name = "CSV input file")]
public string BarSignalFile { get ; set ; }

Thank you in advance

Hello stasha,

You could set a default path, if the user chooses something else then it would change to the user selection. There wouldn't be a way to alert or stop the dialog if a selection was not made, you would have to supply a default either to start with or after the script starts if it was blank.

If there is not a default that could be used a message could be put on the chart letting the user know that the indicator was not configured and they need to re configure its path.

Not sure if the NinjaTrader FilePathPicker works similarly to the System.Windows.Forms.OpenFileDialog method, but the latter returns a System.Windows.Forms.DialogResult and checking if that is System.Windows.Forms.DialogResult.OK allows one to determine if a file was selected or not and act as appropriate.

Thanks.
