CListCtrl problem of Data Update

Hi all
Iam facing problem in listview .Problem is while giving breakpoint I can see values are getting updated but when i am seeing LISTVIEW in my application ,its not getting updated.

Code:

Code Below iam giving breakpoints latitude & longitude values are changing but when i run my application in Listview latitude & longitude are not changing. I try to give invalidate() as well as update but it did not worked it out 


CString strLstItem;
CListCtrl &objLstCtrl = GetListCtrl();

strLstItem.Format("%f", latitude);
objLstCtrl.SetItemText(nItem, 1, strLstItem);

strLstItem.Format("%f", longitude);
objLstCtrl.SetItemText(nItem, 2, strLstItem); 

 

ya i tried invalidate already as well as update also but still it is not working

 

No Shabbir
I am updating that variable only because i can see while giving breakpoint value are getting updated

Code:

CString strLstItem;
CListCtrl &objLstCtrl = GetListCtrl();

strLstItem.Format("%f", latitude);
objLstCtrl.SetItemText(nItem, 1, strLstItem);
[B]objLstCtrl.Invalidate();[/B]

strLstItem.Format("%f", longitude);
objLstCtrl.SetItemText(nItem, 2, strLstItem);
[B]objLstCtrl.Invalidate();[/B]

But still cant fix out this bug

 

Are you actually adding an item to the list first? You can't set an item's text until there is an item in the list. Where is nItem coming from? There should be a call somewhere like:

Code:

  [COLOR="Red"]int nItem=objLstCtrl.InsertItem(0,_T("Latitude:"));[/COLOR]
  strLstItem.Format("%f", latitude);
  objLstCtrl.SetItemText(nItem, 1, strLstItem);

 

Here is the whole function iam pasting will it be help for u

Code:

void CEntityListView::AddEntityToList(int pPosition, TARGET_POS cursor)
int [B]nItem[/B];// =0;
	CString strLstItem;
	CListCtrl &objLstCtrl = GetListCtrl();
	

	int nLstCount = objLstCtrl.GetItemCount(); //(r)Retrieves the number of items in a list view control.

	if(nLstCount == 0)
	{
		POSITION position;

		position = ((CScenGenDoc*)m_pDocument)->GetFirstViewPosition();
		while(position != NULL)
		{
			CView *pView = ((CScenGenDoc*)m_pDocument)->GetNextView(position);
			if(pView->IsKindOf(RUNTIME_CLASS(CEntityDetailInfoView)))
			{
				((CEntityDetailInfoView*)pView)->SetEntityIndex(1);
			}
		}
	}

	if(pPosition > nLstCount)
	{
		strLstItem.Format("%6d", pPosition);
		nItem = objLstCtrl.InsertItem(nLstCount, strLstItem);
	}
	else
	{
		[B]nItem [/B]= pPosition;
	}

                                latitude = cursor->L_Latitude;
				longitude = cursor->L_Longitude;

         strLstItem.Format("%f",latitude);
	objLstCtrl.SetItemText([B]nItem[/B], 2, strLstItem);

	strLstItem.Format("%f", longitude);
	objLstCtrl.SetItemText([B]nItem[/B], 3, strLstItem);

 

I certainly don't see anything there that looks out of place. Are there any warnings or anything else that might indicate some other problem? I'm at a loss at this point.
