Hi,
I see, that Indy is installed with Turbo C++, but I can't get it to work...
I have "old" Turbo c++ version, downloaded 06.09.06.
On clean system, I install prereqs and Turbo c++ (full instalation).
I create new VCL Windows project.
I insert code in the cpp file: " TIdTCPClient *C=new TIdTCPClient(NULL); "
I insert an include: "#include <IdTCPClient.hpp>"
When I try to compile it, there are shown two linker errors about unresolved 
externals:
[Linker Error] Error: Unresolved external 'Idtcpclient::TIdTCPClient::' ...
[Linker Error] Error: Unresolved external '__fastcall 
Idtcpclient::TIdTCPClient::TIdTCPClient

I changed "Library search path" and "Pascal unit search path" and added all 
folders in $(BDS)\lib folder, but it didn't help.

How to make indy to work?

Thank you in advance - it is very important to me, I try to "upgrade" my 
project from Bcb5.

You did not add Indy's actual library into the project.  Since you did not
drop the TIdTCPClient component onto your TForm, the IDE will not insert the
library into the project automatically for you, so you have to do it
yourself separately.  At the very least, you can add the following statement
to your code:

    #pragma link "IdTCPClient"

All that does is tells the IDE where the libraries can be found, but that
does not actually add the libraries themselves to the project.

For some reason, that didn't work for me.
The Linker couldn't find IdTCPClient.OBJ
I tried various combinations of #pragma link "IndyCore.lib"
#pragma link "IndySystem.lib" with and without the lib and
also IdTCPClient.dcu. Finally got it to work with
#pragma link "indy.lib", in the lib/release directory.

I also have a TB97 component package.  I was
wondering how to use that, since there is no
lib files with that, but .pas, .cpp, .dpk, ,.bpk files.

Did you add Indy's .lib file to the project?  You have to do that.

directory.

Don't use a pragma to add the .lib to the project.  Use the IDE's "Add to
Project" option instead.

I misunderstood something
What does #pragma link "IdTCPClient" do?

Another question, I have a Toolbar97 component.
The example programs for CBuilder don't have any
include statements for the component, so I was wondering
how to use it in Turbo Explorer.
