Hi...

I have to develop an Delphi application using MapPoint.
The situation is: There are several branches, each branch has several customers.

First, I use ImportData() method to get the pushpins of the customers.
Then, I use Map.AddPushpin() method to display a pushpin for each branch itself.

But although I add the Pushpins for the branches AFTER importing the customers' pushpins, the symbols of the branch pushpins (stored in "My Pushpins") will be displayed in the background.

See attached image ("Meine Pins" is "My Pushpins" in German ). The green circles are the customers' pushpins imported via ImportData, the blue flag is the branch pushpin.

Has someone an idea how to get the DataSet "My Pushpins" in foreground??

Greetings,

Here a piece of code:

Code:

// First, import the Customers' pushpins

      adoQuery.Open;
      try         
            SetLength(arrDataSets, adoQuery.RecordCount);
            while not adoQuery.Eof do begin
               BranchID := adoQuery.FieldByName('BranchID').AsString;  // get BranchID from Query (necessary to get the right View from SQL Server)               
               arrDataSets[adoQuery.RecNo-1] := SMap.DataSets.ImportData(ExtractFilePath(Application.Exename) + 'serverlink.udl!V_Mappoint_'+BranchID, arrFields, geoCountryDefault, geoDelimiterDefault, 0);
               arrDataSets[adoQuery.RecNo-1].Symbol := ArrCustomerSymbols[adoQuery.RecNo-1].ID; // array of Symbols, for the customer group of each branch an extra symbol
               arrDataSets[adoQuery.RecNo-1].Name   := BranchID;  // give the DataSet a name
               adoQuery.Next;
            end;
      finally
         adoQuery.Close;
      end;
            
// Then, create the Branch pushpins, but they will appear in background...
    
   adoQuery.SQL.Clear;         
   adoQuery.SQL.Add('SELECT Longitude, ');
   adoQuery.SQL.Add('       Latitude, ');
   adoQuery.SQL.Add('       BranchID, ');
   adoQuery.SQL.Add('       BranchName ');
   adoQuery.SQL.Add('  FROM Branches');
      
      adoQuery.Open;
      try
         
            while not adoQuery.Eof do begin
               BranchLocation := SMap.GetLocation(adoQuery.FieldByName('Latitude').AsFloat, adoQuery.FieldByName('Longitude').AsFloat, 0);
               B_Name         :=  adoQuery.FieldByName('BranchName').AsString;
               B_ID           := adoQuery.FieldByName('BranchID').AsString;
               adoQuery.Next;

               // insert a Branch pushpin
               tmpPushpin        := SMap.AddPushpin(BranchLocation, 'Branch location' + B_ID);
               tmpPushpin.Note   := B_Name;
               tmpPushpin.Symbol := symbol_ID;  // an ID of the symbol...
            end;
         
      finally
         adoQuery.Close;
      end;

Hi..
I now solved the problem by loading the branch pusphins with ImportData, too.
But I am still interested in how to move a single DataSet (containing Pushpins) in the background or foreground (like layers in PhotoShop). Because there is often the problem that pushpins of a DataSet overlap the ones of another DataSet.

Hi,

Some objects in Mappoint have a ZOrder method to do that. I don't think pushpins have it.

The prints I do are quite effective in reducing the overlap.
An added benefit is that a pdf can hold a great deal of raster data
which looks good at 15% and also 300%.
If you'd like to see, send me your map and I'll send back a pdf.
