MapForums

Hi MP users,

Yeah I know, I ask a lot, but please, be patient with me.

Well I was looking for info how to get the right pushpinobject in a dataset using the pushpin's name. But in DataSet I couldn't find a method which makes this possible. So I found out that I might need the RecordSet. And with RecordSet I came to a dead end.

My situation is like this: In my Dataset I've for example 200 pushpins saved in it, each pushpin has a name accoording to a number. Now as a user I want to select one of those 200 pushpins on the map which than appears the adres and time in the balloon. How can I achieve that?

I thought I just use the Map.Select() which returns a Pushpin object, if a pushpin is selected and than do: SelectPushpin.GetNote(), which returns a string, with the needed info.

So whatever DataSet the pushpin belongs to, when I select it on the map, mappoint automagically returns the right pushpinobject with all its information, is that right??


Thnx for help.

Hi,

No problem, just ask, that's wy the forum is for

It is not a Dataset method, but ActiveMap method: FindPushpin(string Name) returns the pushpin with the given name.

Well ok,

But suppose I've 3 pushpins with the SAME name, BUT each belongs to another DataSet! Than which of the 3 pushpins will I get??

I thought the one with the current DataSet, or......Mappoint checks also the Lat/Lon to which the pushpin belongs, actually I don't know.


But what I mean is that if I have for example 30 pushpins, with 3 DataSet's, each containing 10 pushpins and they are all displayed on the map. Will MP check the name of a Pushpin, while there are 2 other pushpins with the same name, except that they belong to other two DataSet's? So, how is that?

I hope you understand what I mean

Hi,

I never tryed to try FindPushpin method in another dataset as My Pushpins. I think it works. However if you dont have exclusive names for each pushpin it will not work. I've always used exclusive names.

But a good approach is also to use a linked list where you keep all references for your pushpins in. Then you dont need mappoint methods to find them and you have control in your own program
