Error Importing indicator

[jpkulkarni]

Hi - i have an indicator that compiles just fine and exports also correctly on my dev computer. But when I try to import it on the trading PC, i get some error that I cannot figure out the root cause for.. Any help or pointers would be super helpful

Below is the error I get. The code that it is referrencing is generated code by Ninjatrader and not part of the indicator code i have written.

CS0266: Cannot implicitly convert type 'NinjaTrader.NinjaScript.DrawingTools.TextPosition [C:\Users\Administrator\Documents\NinjaTrader 8\bin\Custom\DrawingTools\@Text.cs(513)]' to 'NinjaTrader.NinjaScript.DrawingTools.TextPosition [C:\Users\Administrator\Documents\NinjaTrader 8\bin\Custom\DMR_Tools.v24.10.19.2.dll]'. An explicit conversion exists (are you missing a cast?),

Hello jpkulkarni,

The error appears to be from the DMR_Tools.v24.10.19.2.dll assembly.

Is this a custom assembly you have created yourself?

Do any classes in this assembly call Draw.TextFixed()?

The error is likely caused by a script using a method such as Draw.TextFixed() which uses an enum for TextPosition. That enum is defined in the core of NinjaTrader; when NinjaScripts are imported, the platform searches for that enum within the assembly being imported and not within the core assembly.

A workaround to resolve this is for the developer to include a custom enum in a custom namespace that has the same properties, such as the various TextPosition values, and then that enum can be cast to the TextPosition type using the fully qualified namespace. This will allow the script to be exported as a compiled assembly and then subsequently it can be imported successfully. Here is an example of a custom enum you could use:

namespace MyEnums
{
public enum TextPosDLL
{
BottomLeft,
BottomRight,
Center,
TopLeft,
TopRight
}
}​

The Draw.TextFixed() method within the script would look like the following:

Draw.TextFixed(this, "tag", "Text", (NinjaTrader.NinjaScript.DrawingTools.TextPosition )MyEnums.TextPosDLL.Center);

For a full working example of this in an open source indicator script you can text exporting as a closed assembly, please see the attached TextPositionDLL.zip.

Thanks Chelsea.. As usual you have been fantastic with these kinds of weird issues. yes. the DMR_Tools is something i packaged but was not sure why it would give me error on import if it didn't give me error at compile time and also at run time on my dev machine. I will try above workaround to see if i can get the get it to work.
