If i use AnsiStartsStr in delphi vcl have the error: undeclared identifier

I allready installed the fix pack but it didn't help. How can i fix this? I tried:

if AnsiStartsStr('CONNECTINFO<-+^+->', socket.receivetext) then
    begin;

In such a situation the first task is to look in the documentation. There are actually two functions with that name. They are documented here:

• http://docwiki.embarcadero.com/Libraries/XE5/en/System.AnsiStrings.AnsiStartsStr
• http://docwiki.embarcadero.com/Libraries/en/System.StrUtils.AnsiStartsStr

The title of the documentation tells you the unit you need. Either

• System.AnsiStrings or
• System.StrUtils

So you need to add the appropriate unit to your uses clause. I cannot tell for sure which function you need.

If you have problems searching the documentation try the advice here: How can I search for Delphi documentation? Of course you should just be able to click in the unrecognised identifier and press F1.
