You don't know how to make your list view owner drawn OR you don't know how to set text color OR both?

I have done exactly this...

In your (MFC) NM_CUSTOMDRAW handler, you need code like this:

void whtever the clas name is::OnCustomDraw(NMHDR *pNMHDR, LRESULT *pResult)
{
   LPNMLVCUSTOMDRAW pNMLVCD = reinterpret_cast<LPNMLVCUSTOMDRAW>(pNMHDR);
   *pResult = CDRF_DODEFAULT;
   switch(pNMLVCD->nmcd.dwDrawStage)
   {
   case CDDS_PREPAINT:
      *pResult = CDRF_NOTIFYITEMDRAW;
      break;
   case CDDS_ITEMPREPAINT:
      {
         const COLORREF mainColor = whatever the background text colour is;
         const COLORREF altColor = whatever the alternate background colour is;
         const COLORREF mainTextColor = whatever the main text colour is;
         const COLORREF altTextColor = whatever the alternate text colour is;
         const size_t row = pNMLVCD->nmcd.dwItemSpec;
         pNMLVCD->clrTextBk = (1==row%2)?altColor:mainColor;
         pNMLVCD->clrText = (1==row%2)?altTextColor:mainTextColor;
         *pResult = CDRF_NEWFONT;
      }
      break;
   };
}

Show your code. I have no idea where HANDLE_NM_CUSTOMDRAW comes from...

it never reaches in the below case statement

case CDDS_ITEMPREPAINT:

Do you have any items? If not, it's not going to.

The code in the CDDS_PREPAINT case block is what causes the custom draw state machine to call your handler for CDDS_ITEMPREPAINT.

Well, add the LVS_OWNERDRAWFIXED[^] style to your list view (preferably in the resource editor if you are working with a dialog template). Then, in the parent of your list view handle the WM_DRAWITEM[^] message, this gives you a DRAWITEMSTRUCT [^] structure that contains a DC you have to use to perform the drawing, use SetTextColor[^] to set a color before you draw the texts using DrawText[^]. Hope this helps.

Hi,

Is there any possibility to get Geo location using IP address ?

I also searched on net but could not get the desired stuff.

So we're getting again and again your question?
Please, go building, as suggested, your own database instead.
(just kidding, man...)

Please give any suggestion, how to do it?

Since commercial applications and libraries uses large databases for the purpose, I suppose your effort would be a waste of energy.
