What version of Indy are you actually using?  It makes a difference in how 
the code has to look.

What type of members does CLIENTTOSERVERCMD actually contain?

Do not use the Socket property directly like that.  TIdTCPConnection (which 
TIdTCPClient derives from) in Indy 9, and TIdIOHandler in Indy 10, have many 
reading/writing methods of their own that you need to use instead.  For 
instance, in Indy 9, you could use TIdTCPConnection::WriteBuffer(), and in 
Indy 10 you could use RawToBytes() and TIdIOHandler.Write(TIdBytes) instead.

I'm using C++ Builder 2007. Not sure what version of Indy comes with that.

Indy 9 (not sure which build) and Indy 10.1.5.  So how you send your struct 
still depends on what version of Indy you configured when you installed the 
IDE.  As I mentioned, your code will look different depending on which 
version you are actually using.  Right-click on any Indy component in the 
form designer to find out.

You didn't answer my other question - what does CLIENTTOSERVERCMD contain 
inside of it.  I only ask because if you are using AnsiString or other 
dynamically-allocated fields, then you can't send your struct as-is at all, 
regardless of your Indy version.


Gambit 

Yes, I know I cannot use AnsiString. My structure looks like this:

typedef struct ClientToServerCommand
{
       int nMessageType;
       char cGUID[255];
       char cUserData[255];
} CLIENTTOSERVERCMD;

I just checked the Indy version and is 10.1.5

Thanks for your help.

In that case:

    CLIENTTOSERVERCMD mycmd;
    ...
    IdTCPClient->IOHandler->Write(RawToBytes(&mycmd, sizeof(mycmd)));
