Hello All,

As per your suggestion, i have been trying to learn MFC and try to replicate the problem i am solving in the legacy code.

I have comeup with the following code:, But the issue here is the list is growing in the opposite direction from what i was expecting !!!

Code:
map<int, vector<int>> m = { { 1, {1,3,4 }} ,{ 2, {4,5,6 } } };
map<int, string> n = { { 1, "Site1", } , { 2, "Site2"} ,{ 3, "Site3" },{ 4, "Site4" },{ 5, "Site5" },{ 6, "Site6" } };


BOOL CMFCApplication2Dlg::OnInitDialog()
{


	// TODO: Add extra initialization here

	priya_list.SetExtendedStyle(LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES | LVS_EX_ONECLICKACTIVATE);

	int nItem = priya_list.InsertColumn(0, _T("Cell"), LVCFMT_LEFT, -1, 0);
	priya_list.InsertColumn(1, _T("Site"), LVCFMT_LEFT, -1, 0);

	int centralsite;
	vector<int> sites;
	bool bIsfirstCentralsite(false);
	for (const auto pair : m)
	{
		bIsfirstCentralsite = true;
		string centreId;
		int index = pair.first;
		if (index == 1)
		{
			centreId = "first";
		}
		else
		{
			centreId = "second";
		}

		CString ccetre(centreId.c_str());
		for (const auto site : pair.second)
		{
			int nItem(0);
			if(bIsfirstCentralsite)
				nItem = priya_list.InsertItem(0, ccetre);
			else
				nItem = priya_list.InsertItem(0, _T(""));

			auto itr = n.find(site);
			string sSiteId = itr->second;
			CString cSiteId(sSiteId.c_str());
			priya_list.SetItemText(nItem, 1, cSiteId);

			bIsfirstCentralsite = false;

		}
	}

}
Sorry my code maynot be well written, but i am able to replicate the issue i have.

What i wanted is:

Cell Site

first site1
site3
site4

second site4
site5
site6

Basically, first has sites 1,3,4 and second has sites 4,5 ,6

Hope i am able to convey the problem i am facing


thanks a lot

Again, thanks a lot for having patience with my naive questions..

Merry Christmas and Happy new year

Best wishes
