triangle Draw objects and remove object issue

[ballboy11]

I have an issue deleting triangle objects.
For some reason it will not allow me to delete. the Picture below is my error.
It is simple logic but it will not delete the object.

// no more than 200 triangles to be printed on chart
if (nTriangleCount > 200)
{
nTriangleCount = 0;
bTriangleGraphicReached = true;
}


if(bTriangleGraphicReached == true)
RemoveDrawObject("Tangle"+ nTriangleCount.ToString());

Draw.TriangleDown(this, "Tangle" + nTriangleCount.ToString(), true, 16, dSwingHigh + 1 * TickSize, Brushes.Tomato);
nTriangleCount++;

Hello ballboy11,

Thank you for your note.

Which drawing object are you trying to remove, the last drawn or all drawing objects?

I look forward to your reply.

No I am not removing ALL objects
I am removing the object by tag ID.


My triangle list is from 0 to 199

when the max is reached I reset the count to zero, then I start removing the Triangle object 1 at a time when needed.

ie RemoveDrawObject("Tangle0");

then Draw.Triange( this, "Tangle0",,,,,

Hello Ballboy,

Without the full code we're unable to test on our end.

If you'd like to upload the full code I can take a look and see if anything jumps out. Or if you'd prefer to email a copy, send to platformsupport[at]ninjatrader[dot]com with Attn: Alan P in the Subject line. Also within the email please include a link to this thread, and the files.

I look forward to your reply.

Here is the zip file but I think I found the issue.

I don't think remove draw object is working or does it actually remove a draw object.

"Tangle" + nNumber.ToString(); would be my tag.

If I only draw one type of object such as triangle up only, I will have no issues. Same as triangle down i will have no issues.

If i use the Same Tag name, try to delete the tag name and draw a DIFFERENT object it will give me an error.


I can ONLY draw 1 type of Object per tag name.

Example

TangleUp + nNumber.ToString() for up triangle
TangleDown + nNumber.ToString() for donw triangle

Result. NO ISSUES

DeleteDrawObject("Tangle" + nNumber.ToString());

Then Draw one or the other.

Tangle + nNumber.ToString() for up triangle OR
Tangle+ nNumber.ToString() for down triangle

ERROR Will result.

In Conclusion Delete DrawObject has no effect or DeleteDrawObject does not work.

Hello ballboy11,

Yes, you should not use the same tag name for two different drawing objects, up vs down triangles. The error from the log screen shot looks related to this rather than RemoveDrawObject not working.

Please let us know if you need further assistance.
