Can I check the Indy version installed?

I need to use the latest Indy component library version. Can I get the library version by some source code command or any other trick to make sure I'm using the correct lib. I know I'm using the indy....160.bpl - this is what my Delphi XE2 says while moving the mouse over the component bar. The latest INDY lib I take from Fulgan Indy

How to get version of Indy by using an Indy component at runtime ?

As @Remy pointed out in his comment, you can get the Indy version from any Indy component by using the Version property. Here's a sample using TIdHTTP component:

procedure TForm1.Button1Click(Sender: TObject);
begin
  ShowMessage('Indy version: ' + IdHTTP1.Version);
end;

How to get version of Indy without an Indy component at runtime ?

You can get the whole version string in Indy's versioning format:

<major>.<minor>.<release>.<build>

from the gsIdVersion constant defined in the IdVers.inc file included in the IdGlobal.pas unit in a way like follows:

uses
  IdGlobal;

procedure TForm1.Button1Click(Sender: TObject);
begin
  ShowMessage('Indy version: ' + gsIdVersion);
end;

or if you have Indy revision at least since 25th October 2012 (4850), you can use the individual version information elements, whose are defined in the same include file as mentioned before e.g. this way:

uses
  IdGlobal;

procedure TForm1.Button1Click(Sender: TObject);
begin
  ShowMessage('Indy version: ' +
    IntToStr(gsIdVersionMajor) + '.' +
    IntToStr(gsIdVersionMinor) + '.' +
    IntToStr(gsIdVersionRelease) + '.' +
    IntToStr(gsIdVersionBuild)
  );
end;

How to get version of Indy at design time ?

To get Indy version at design time you can simply right click any of the Indy's components dropped on a form and open its About box through the About Internet Direct (Indy)... menu item.

Where are the version information defined ?

As I've mentioned before, it's in the IdVers.inc include file stored in the ..\Lib\System\ folder of the library and it might be the next option of how to get the Indy's version information.

Disclaimer

Some of what was mentioned here applies to the Indy's most recent version at this time, but I'm not sure if it applies also to all older versions (such as Indy 9 for instance).

If your application already has an instance of an Indy component (which inherits TIdBaseComponent), you can get the version simply by

Version := SomeIndyComponent.Version;

in the current version, this function will return 10.5.9.0
