new entity created from modeless dialog do not display well

[Anonymous]

I have a modeless dialog, in the dialog, there is a button, in the button click event function , I created a polyline sucessfuly, but the entity do not display well. Please look the picture I have uploaded.

  the entity look darker than the normal.   in the fuction, I have called fuctions like

"actrTransactionManager->flushGraphics();
    acedUpdateDisplay();"

" acedGetAcadDwgView()->SetFocus();
        acedGetAcadDwgView()->SendMessage(WM_MOUSEMOVE); "

but it dosen't work. 

the only way that makes it work is to call the "regen" command.  but, usually, the dwg is very large. and the 'regen' command takes too much time.

In order to other's can check this behaviour you have to post sample code and clarify AutoCAD version.

sorry, too busy these days. i have made an example, and the ARX version is AutoCAD 2008.

and I have found something.

void CModelessDlg::OnDraw()
{
    acDocManager->lockDocument(curDoc(), AcAp::kWrite, NULL, NULL, TRUE);
    ads_point pt;
    pt[X] = pt[Y] = pt[Z] = 0.0;
    AcDbObjectId idEnt = DrawCircle(pt,4,NULL,NULL,_T("new"));// here , if the last param is NULL(not _T("new")). then the new entity displays well.
    
    ZoomEnt(idEnt,4);
    actrTransactionManager->flushGraphics();
    acedUpdateDisplay();
    acDocManager->unlockDocument(curDoc());

}

Replace function InsureLayerExist with:

AcDbObjectId InsureLayerExist(const TCHAR* szLayer)
{
	if (NULL == szLayer || 0 == _tcscmp(szLayer,_T("")) ) 
		return AcDbObjectId::kNull;
	AcDbLayerTable *pLayerTbl;
	AcDbObjectId idLayer = 
		acdbSymUtil()->layerZeroId(curDoc()->database());
	curDoc()->database()->getSymbolTable(pLayerTbl, AcDb::kForRead);
	if ( Acad::eOk != pLayerTbl->getAt(szLayer,idLayer)) 
	{
		AcDbLayerTableRecord *pLayerTblRcd = new AcDbLayerTableRecord;
		pLayerTblRcd->setName(szLayer);
		if (pLayerTbl->upgradeOpen() == Acad::eOk) {
			pLayerTbl->add(idLayer,pLayerTblRcd); 
			pLayerTbl->downgradeOpen();
		}
		pLayerTblRcd->close();
		pLayerTbl->close(); 
		applyCurDwgLayerTableChanges(); // Main difference with your code 
	} else {
		pLayerTbl->close(); 
	}


	return idLayer;
}
