Commands in ControlBar

Hi People ....

I make a ControlBar in a ODCL Test Project.

I put in ControlBar an PictureBox with Clicked Event.
In my c:TestProject_ControlBar1_PictureBox1_OnClicked I put this code:

(c:TestProject_ControlBar1_PictureBox1_OnClicked (/)
  (command "line")
)

But It returns

error: invalid AutoCAD command: nil

I don't know what is happening ...

Anyone have idea ?

Thanks ...

Select the PicBox, in the properties panel change the "Event Invoke" = 1-Asynchronous

Thanks Bazza.
It really works.
But I have in the same PicBox an OnMouseEntered and OnMouseMovedOff event.
And each mouse move on the PicBox put the function return in command line.

Have any command to avoid this command return ?

Bellow the code:

(defun c:TestProject_frmTest_PictureBox1_OnMouseEntered (/)
(dcl_Control_SetPicture TestProject_frmTest_PictureBox1 174)
(princ "ttt")
)
(defun c:TestProject_frmTest_PictureBox1_OnMouseMovedOff (/)
  (dcl_Control_SetPicture TestProject_frmTest_PictureBox1 173)
)


Put T in command line

Thanks for all

Hi, Oswald,

add a (princ) in the end.

(defun c:TestProject_frmTest_PictureBox1_OnMouseMovedOff (/) 
      (dcl_Control_SetPicture TestProject_frmTest_PictureBox1 173)
      (princ)
)

I add (princ) but on each MouseOver/Out it makes new line print
Example:
Command:

You can set Event Invoke back to Synchronous, but execute your (command) calls from within a different function that you initiate by calling (dcl_SendString) or (dcl_DelyedInvoke).

By the way, if all goes according to plan, the next build of OpenDCL will not need the OnMouseEntered and OnMouseMovedOff handlers to switch the Keep Focus setting.

Following your instructions I test using dcl_SendString and dcl_DelayedInvoke.

With DCL_SendString the command executes only after next command send by user.
The command was:
(dcl_SendString "(line)")
Don't solve ...

Then I test DCL_DelayedInvoke ...
(dcl_DelayedInvoke 100 "(line)")
Then I solve my problem. ...

Now it runs correctly ...

Thanks guys ..

You needed to add a '\n' at the end.

Really ... It works ...
I use thist:
(dcl_SendString "(line)\n")
Then run ...

What's the best way ?
dcl_SendString or dcl_DelayedInvoke ?

Thanks for your answer
But what is the best method to use ?
SendString or DelayedInvoke ...
Or they're the same ?

I think he's suggesting that either one works just as good.
I'd use (dcl_SendString) so I don't have to deal with the delay, but that's just me... :)

You can use whichever you prefer; for your purposes they are identical.
