I feel I can only use multithreading or multi-process implementation, yield impact efficiency

1, building a popup! Type of the window, put on your GIF images, the name of the stored as w_base_wait;
2, the following code. Save as n_cst_thread_basewait sru, right-click on your PBL again import... Get a Custom called n_cst_thread_basewait Class;

 $PBExportHeader $n_cst_thread_basewait. Sru 
$PBExportComments $on or off waiting threads window 
Forward 
Global type n_cst_thread_basewait from nonvisualobject 
End type 
End forward 

Global type n_cst_thread_basewait from nonvisualobject 
End type 
Global n_cst_thread_basewait n_cst_thread_basewait 

The type as 

End as 

The type variables 

End the variables 

Forward as 
The public function integer of_close_wait () 
The public function integer of_open_wait () 
End as 

The public function integer of_close_wait (); If isvalid (w_base_wait) then close (w_base_wait) 

Return 0 
End the function 

The public function integer of_open_wait (); If not isvalid (w_base_wait) then open (w_base_wait) 

Return 0 
End the function 

On n_cst_thread_basewait. The create 
Call super: : create 
TriggerEvent (this, "constructor") 
End on 

On n_cst_thread_basewait. Destroy 
TriggerEvent (this, "destructor") 
Call super: : destroy 
End on 

3, in the application to define a global variable n_cst_thread_basewait gwait and add a function called of_cthread_wait, return an integer:

 ErrorReturn err 
Err=SharedObjectRegister (" n_cst_thread_basewait ", "nwait") 

IF err & lt;> Success! THEN 
Messagebox (', 'registered Shared object failed! ', stopsign!) 
The return - 1 
END the IF 
Err=SharedObjectGet (" nwait gwait) 
If err & lt;> Success! Then 
Messagebox (', 'generated from the Shared object registered thread failure! ', stopsign) 
The return - 1 
End the if 
SharedObjectUnregister (' nwait) 

If isvalid (gwait) then 
Return 0 
The else 
The return - 1 
End the if 

4, written in the application of the open event: of_cthread_wait ()
5, need to open for window place to write: gwait. Post of_open_wait (), where the need to close the write: gwait. Post of_close_wait ()
