Hello,
I'm just starting with Indy10 on C++ 2007, trying to build a simple TCP
client and server. The Execute() event handler for the server is shown
below. It's trying to simply read a string from the connection and echo it
back to the client. As soon as the client connects to the server, an access
violation occurs in the call of ReadLn(). The error message says "Read of
address 0x0000008C". Can anyone help me past this first hurdle? Thanks.
Joe
void __fastcall TForm1::IdTCPServer1Execute(TIdContext *AContext)
{
AnsiString Text = AContext->Connection->IOHandler->ReadLn();
AContext->Connection->IOHandler->WriteLn( Text );
MessageCountNumLab->Value += 1;
MessageCountNumLab->RightText = Text;
}
The RAD2007 directory structure contains the Indy10-related folders listed
below. I have a ways to go to figure out how to get all of the correct files
from the various folders in the Indy10 install directory structure to this
one.
Help \ Doc \ Indy
Include \ Indy10
Lib \ Indy10
Lib \ Debug \ Indy10
Source \ Indy \ Indy10 \ Core
Source \ Indy \ Indy10 \ Protocols
Source \ Indy \ Indy10 \ System

If you want to install the Indy components into the IDE's palette, yes.
Those are Indy's design-time packages.

Should be, as long as you make sure that the Indy9 folder does not appear in
front of your new Indy10 folder in a project's Path settings. Otherwise,
the compiler will likely pull in the wrong files and cause all kinds of
problems.

Not strictly required, but probably not a bad idea. Let configuration that
way, since everything is already set up for Indy 10 that shipped with the
IDE.

No. Doing that will put the files in other locations.

They get created during the compiling stage, not the installing stage,
provided the "Generate all C++ files" setting is enabled in the Project
Options of each package. I don't know if that setting is enabled by
default. I'm not the one who makes the package files.

Using DelphiWin32, I was able to open and build the 3 DPK files listed
below. I chose the "120" files over the "100" and "110" versions. Was that
the correct decision?
System \ IndySystem120.dpk
Core \ IndyCore120.dpk
Protocols \ dclIndyProtocols120.dpk
I also was able to open and build these 2 additional DPK files. Was that
necessary?
Core \ dclIndyCore120.dpk
Protocols \ dclIndyProtocols120.dpk
Is it sufficient to delete the files from the Lib\Indy10 and Include\Indy10
folders in the BDS\5.0 directory structure and leave the Indy9 folders
alone?
Once I delete the files from the BDS\5.0 directories, do I need to copy
files from the Indy10 build structure to the BDS\5.0 structure, or does that
happen automatically I "install" the new package? When I right-clicked on
the "bpl" file in the Delphi project window, I see there is an "Install"
menu item. Is that how I install the newly built packages? Finally, I've
never used Delphi before. Do C++ header files get created during the package
installation?
Sorry for all the questions. Teach a man to fish...

Then you are using a very old version. 10.2.3 is the currently available
build. There have been a lot of internal changes between 10.1.5 and 10.2.3.
So whatever you are hitting may not even be an issue anymore. Why it was
happening in the first place, I cannot say without seeing a stack trace
leading up to the exception.

Look for all of the "Id*" files in CodeGear's folder hierarchy.

Because you are opening the .NET version of the files.
Go into the System, Core, and Protocols subfolders and compile the
IndySystem, IndyCore, and IndyProtocols DPK projects individually. Do not
compile the ones that have "Net" at the end of their filenames, as those are
for .NET. The Win32 versions do not have "Net" at the end.

Hi Remy,
I am using 10.1.5, the version delivered with RAD2007. Unfortunately, I
still don't know how to update to a new version. In an earlier thread, you
said:
"All I can say is to uninstall the old packages from the IDE, then
physically remove the files from the machine, then you can compile and
install the new packages."
I understand how to uninstall a package. Can you say more about which files
need to deleted, and how to build the new packages? Do I simply open the
"bdsproj" projects in the "Lib" folder that are in Indy10 distribution? I
installed the DelphiWin32 personality, but not DelphiDotNet, and when I try
to open those projects, I get a message that I need the DelphiDotNet
personality. Does that mean I need to uninstall RAD2007 and start over?
If there is some way that I can purchase some support from Atozed, I would
be willing to do that. It seems so strange that you are doing all of this
great work to improve Indy, but there are no instructions to install new
versions.

Are you using the version of Indy 10 that shipped with CB2007? If so, then
that is an old version. Try upgrading to the latest from Indy's website and
see if the problem continues.
