Hi,

Use that page for a bit as user and study how they pass the search query, via Post or Get.
Use TIdHTTP to do the query in either case.

HTH,

Andrew

P.S. For further help, please specify the page.

Parameters:

Hi,

I'll try to post something tomorrow morning, ok?
I don't have a chance to try things out for today.

Or, send in the code you tried, so that we'll give a
look at it together.

Cheers,

Andrew

Hi,

Well, I gave an eye to the Post method in the IdHTTP component.
It's overloaded, so you have several versions, but in all of them there's a
string list parameter.

You can do something like this:

var Params : TStringList;

begin
 
   Params := TStringList.Create;
   Params.Add( 'SELECT='+Selection );
   Params.Add( 'FOR='+Title );
   IdHttp1.Post(...,Params,nil );

end;

Use a TStream in the third param if you want to get a result back.

HTH,

Andrew
