ScreenShot Addon

[cutzpr]

Yes I removed my previous test before importing. I am not sure why this is occurring, I gave up and will just call it as an indicator vice an static addon.

Hello cutzpr,

Thank you for the reply.

Had you removed the test you were conducting prior to importing the provided zip file using the Tools -> Import -> NinjaScript?

I am not seeing this error when using the attached sample on my side. The error is stating the extension method GetScreenshot cannot be found which would generally indicate a missing using statement. You have also shown an error surrounding a conversion for the window and chart, but that is the same code from the indicator which you provided a link to and I assume you had tried and had success with?



I look forward to being of further assistance.

I had errors importing the ninjascript addon you provided. I get the following errors. I am using 8.0.15.0 64-bit .

Default Error compiling import assembly: c:\Users\XXXXX\Documents\NinjaTrader 8\tmp\Import\Files\bin\Custom\AddOns\ScreenShotAdd on.cs(35,65) : error CS1061: 'NinjaTrader.Custom.AddOns.Chart' does not contain a definition for 'GetScreenshot' and no extension method 'GetScreenshot' accepting a first argument of type 'NinjaTrader.Custom.AddOns.Chart' could be found (are you missing a using directive or an assembly reference?)

Hello cutzpr,

Thank you for the post.

I was unable to see the same error you had, but I did see a threading error when I tried this as you would need to use a dispatcher for this type of code.

I created a small sample in an addon of the previous code and simplified the use. From the strategy you could call:

NinjaTrader.Custom.AddOns.ScreenShot.SaveChart(ChartControl);

I look forward to being of further assistance.

I am trying to convert the screenshot indicator found here https://ninjatrader.com/support/foru...d.php?p=474845 to an addon but I keep receiving the error below but this is exactly how the indicator cast the Window as a chart.

Cannot implicitly convert type 'NinjaTrader.Custom.AddOns.Chart' to 'NinjaTrader.Gui.Chart.Chart'
Cannot convert type 'System.Windows.Window' to 'NinjaTrader.Custom.AddOns.Chart' via a reference conversion, boxing conversion, unboxing conversion, wrapping conversion, or null type conversion

From my strategy I am calling it using

ScreenShot.chart = Window.GetWindow(ChartControl) as Chart
ScreenShot.SaveChart();
