PromptPointOptions with no message always prints a colon (:)

Hi,
I would like to use a PromptPointOptions with no message.
I use it when user clicks a button and I always get a colon printed to the command line. They even keep stacking in the same line.

PromptPointOptions pPick = new PromptPointOptions(""); pPick.Message = ""; // this line does not change anything

I do change some system variables before calling the prompt, but this should not have any effect.

// Set PolarMode to include 1 + 4 // ("Relative to last segment" and "Additional angles") Application.SetSystemVariable("POLARMODE", 5); // set AUTOSNAP to include everything Application.SetSystemVariable("AUTOSNAP", 63); Application.SetSystemVariable("ANGBASE", inLineAngle); Application.SetSystemVariable("ANGDIR", 1);

This is how picking the point looks like with Dynamic Input on or off. The colon is always here. If I add a message to the prompt, it just shows before the colon.

And the command line, see the colons:

Firstly, it is always good to provide a meaningful prompt and command line when you expect user to interact to the editor, even the action is initialized from a dialog box when user click the button "Pick Point >". Imaging this: after user clicks the button, the dialog is hidden, before the user picks the point, he/she gets a phone call for lengthy talk. When the talk is done, he/she is facing the Acad editor with empty command line and could not figure out where he/she was left.

Anyway, using empty prompt or not, you should ALWAYS start the prompt with new line ("\n"):

PromptPointOptions pPick = new PromptPointOptions("\n");

PromptPointOptions pPick = new PromptPointOptions("\nSelect a point:");

The colon remains even with the new line.

For now, I solved my problem by using the NOMUTT system variable. Nothing gets printed to the command line. However the colon still remains in the field next to the mouse when picking a point, so I've set the 'Pick a point' message to be shown there.

object nomutt = Application.GetSystemVariable("NOMUTT"); Application.SetSystemVariable("NOMUTT", 1); PromptPointOptions pPick = new PromptPointOptions("Pick a point"); //... // restore system variable Application.SetSystemVariable("NOMUTT", nomutt);

If somebody knows of how to omit the colon without using the NOMUTT, the answer is stil welcome.
