ampersand problem

Hi all. I have noticed a strange behavior of a my application. I use TIdHTTP in Delphi 7 to contact a php page on my server. Since parameters to send are in a StringList and I use Get method, I build url this way

url := 'http://mysite.com/mypage.php?' + '&0=' + TIdURI.ParamsEncode(sl[0]) + + '&0=' + TIdURI.ParamsEncode(sl[1]); and so on...

The problem is that ampersand disappears and if I do a Showmessage to see the builded url I have something like:

'http://mysite.com/mypage.php?param1=abcparam2=def

and obviiously get call fails.

Any idea?

If the first letter after your wanting ampersand gets underlined, this issue is from showmessage(). An apersand is often used to declare the coming letter as shortcut. If you want to debug your url with showmessage() you should use
ShowMessage(StringReplace(url, '&', '&&', [rfReplaceAll]));

Open in new window


However this should not affect your http engine.

Thanks, acbxyz. You're right: doubling ampersands makes them to appear ion the ShowMessage but this doesn't affect the http engine. Now I'll have to understand why something worked fine since some week ago now it fails :-(
I'm going to give you points since you have solved the ampersand problem.

Thanks.
