You could use the Progress Bar API. See core_rxmfcapi.h:

// Progress Bar API

/* acedSetStatusBarProgressMeter
 * Creates a progress meter on AutoCAD status bar.
 * Returns 0 if it successfully creates the label and progress meter. 
 * Otherwise -1
 */
int acedSetStatusBarProgressMeter(const ACHAR* pszLabel, int nMinPos, 
                                  int nMaxPos);
/* acedSetStatusBarProgressMeter
 * Call this with a positive value within the range specified to set 
 * the current position of the status bar.  
 * Pass a negative number to add an amount to the current position (relative).
 */
int acedSetStatusBarProgressMeterPos(int nPos);

/* acedRestoreStatusBar
 * Resets AutoCAD status bar
 */
void acedRestoreStatusBar();

To initialize: acedSetStatusBarProgressMeter(L"My progresss text", int nMinPos, int nMaxPos)

You have to figure out yourself how nMinPos and nMaxPos are about to work for you.

To "sync": acedSetStatusBarProgressMeterPos(pos);

To "close": acedRestoreStatusBar();

Example:

int count = 123;
int progErr;
progErr = acedSetStatusBarProgressMeter(L"My Progress:", 0, count-1);

for (int i=0; i<count; ++i)
{
	DoMyStep(i); // <-- your code
	if (!progErr)
	    acedSetStatusBarProgressMeterPos(i);
}
if (!progErr)
	acedRestoreStatusBar();

I am wondering how to implement this . I mean do I need to keep this in a separate thread or I need to create a callback function which will show its progress each time an item ie part of item is being imported . What is the best approach ?

I gave a simple example in my last post. This could be within a long-running registered command-function.

Just call acedSetStatusBarProgressMeterPos(pos) whenever another piece of work is done. No callbacks or separate threads needed.

I'm not sure whether the progress bar API would work when called from another thread because ObjectARX is single-threaded.

Is the process for which you want to display the progress running in a registered command?
