Hallo,
Ich habe ein Programm mit AVR programmiert, dass mit einem Delphi 
Programm zusammenarbeiten soll. Dabei hatte ich zunächst die 
Fehlermeldung bei meinem Delphiprogramm:
unable to open comport win error code 2

Nachdem ich den Anschluss auf ein anderes Comport gelegt hatte kam zwar 
die Fehlermeldung nicht mehr, aber das Programm empfängt keine Daten von 
meinem AVR-Board. Im I-Net habe ich dann gefunden, dass ich die 
Komponente comport library 3.1 zur Abfragung der Comports benötige. 
Stimmt das?

Ich wollte diese Komponente dann anhand der Readmedatei installieren:

6. Installation
------------------------------------------------------------------------ 
--------
Remove all previously installed files of ComPort Library (TComPort
component). Create a new folder under Delphi directory and extract
Sources zip file into new folder. Add to the Library Path the new
ComPort folder (Tools-Environment Options-Library-Library Path).

For Delphi 2006:

Use the instructions below for all other Delphi
versions.  But, note that Delphi 2006 supports both Delphi and
C++ Builder.  I recommend installing CPort while running Delphi 2006
in the "all personalities" mode of Delphi, rather than in the Delphi
only personality.  That helps make sure CPort gets installed dual-mode,
with both Delphi and C++ Builder support.  Note that for some reason,
I find the .LIB files get stored into the CPort directory instead of
the $BDSPROJECTS/BPL directory.  So, after you install CPort, double
check to make sure the .LIB files are in the right spot.

Finally, the .HPP files also get stored in the  CPort directory. Either
move them to a folder already in the C++ source path, or add the CPort
directory to the C++ source path.

Otherwise, follow the directions below, and also read the C++ Builder
notes:

For Delphi 3, 4, 5, 6, 7, 2005 & C++ Builder 4, 5, 6:
(C++ Builder users also need to read the C++ Builder notes)

Use "File/Open" menu item in Delphi/C++ Builder IDE to open
ComPort run-time package source file (see above). Click "Compile"
button in Package window to compile the library. Now move run-time
package library file or files (see above) from ComPort folder to a
folder that is accessible through the search PATH (e.g. WinNT\System32).

Now you have to install design-time package. Use File/Open menu item
to open design-time package source file (see above). Click "Compile"
button in Package window to compile the package and "Install" button
to register ComPort into the IDE. ComPort components appear in
"CPortLib" page of component pallete.  If it complains that it
can't install it because it can't find a library, you probably
did not put the run-time package in the search path. You might
not get this error until the next time you try to start
Delphi/C++ Builder.

Note: Do not save packages under Delphi/C++ Builder IDE.

For C++ Builder 3
(C++ Builder users also need to read the C++ Builder notes)

C++ Builder 3 does not have a "Package window" like the other products.
So, installation is slightly different.

Use "File/Open" menu item in Delphi/C++ Builder IDE to open
ComPort run-time package source file (see above). Compile the
package from the project menu or Ctrl-F9. Now move run-time
package library files (see above) from ComPort folder to a folder
that is accessible through the search PATH (e.g. WinNT\System32).

Now you have to install design-time package. Use File/Open menu item
to open design-time package source file (see above).  Compile the
package from the project menu or Ctrl-F9.  To install the package
into the IDE, go to the Component menu, "Install Packages" option.
Click the Add button.  Browse to the design-time library and select
it.  If it complains that it can't install it because it can't find
a library, you probably did not put the run-time package in the
search path as described above.

Note about Delphi 2:

Note: Delphi 2 is no longer suported, however, with some minor changes,
it should compile under Delphi 2 as well.

Use "Component/Install" menu item to add "CPortReg.pas" unit to the
component library. This unit registers ComPort components on
"CPortLib" page of component pallete.


7. C++ Builder Notes
------------------------------------------------------------------------ 
------
The .hpp file C++ Builder creates for cport.pas will have a bug in it.
The first time you compile a project, you will get one or two duplicate
definitions within the EComPort exception class.  It seems to be safe to
delete or comment out the duplicates.

Also, the CPortCtl.HPP may have a bug in it.  If you get an error about
the following being ambiguous;

typedef TBitmap TLedBitmap;

Change it to:

typedef Graphics::TBitmap TLedBitmap;

If someone knows how to fix these more cleanly, please post what you
find to the CPort Forum so that we can incorporate your findings in
future revisions.


8. Installing help file (not available for Delphi2005)
------------------------------------------------------------------------ 
------
In Delphi/C++ Builder, go to the Help menu, customize item. You should 
be
presented with a tabbed notebook, "Contents" tab selected. Click the + 
(Add Files)
button. Browse to the CPort directory. Select CPort.toc.

Click on the "Index" tab. Click Add Files. Select CPort.hlp. Click on 
the
"Link" tab. Click Add Files. Select CPort.hlp. Select File Menu/Save 
Project
Item. Exit program. Note that Borland's OpenHelp utility does not prompt 
you
if you close the program and forget to save your changes, so you must 
remember
to do so yourself.


9. Known problems and issues
------------------------------------------------------------------------ 
-----
  1.) OnRxBuf event handler problem in Delphi IDE

      If user double clicks on OnRxBuf event in Delphi IDE, message pops 
up
      saying: "Property and Method ComPort1RxBuf are not compatible".
      This is a Delphi IDE bug, since it can't handle untyped parameters
      like Buffer parameter of OnRxBuf event.

      Solution: Application has to assign OnRxBuf handler manually in 
code.

  2.) Two serial ports sharing the same IRQ address

      Some users of Windows 95/98 have reported that application can't 
have
      two TComPort components open simultaneouslly if serial ports share 
the
      same IRQ address. This usually COM1/COM3 and COM2/COM4.

      Solution: Not known yet.

  3.) No integrated help for Delphi 2005 or 2006.

      Solution:  Manually open .HLP file with Windows Help.



Allerdings setze ich schon beim C++ Builder aus! Könnt ihr mir helfen, 
wie ich die restlichen Schritte erfüllen kann?

Ich benutze Delphi 2005

Danke,
Ludwig

Da waere eine Delphi newsgruppe bei Codegear.com die passendere Wahl

Frueher hat man fuer die Komponenten bezahlt und bekam dafuer auch 
Support. Heute bezahlt man vielleicht nicht mehr.
Fuer die dreisten sind emails der Autoren erwaehnt...

>Fehlermeldung bei meinem Delphiprogramm:
>unable to open comport win error code 2

Bei "deinem" Delphiprogramm? Wenn du das selber programmiert hast, 
solltest du doch auch wissen, was diese Fehlermeldung bedeutet?

>Im I-Net habe ich dann gefunden, dass ich die

>Stimmt das?

Das musst doch du selber wissen, welche Komponenten in deinem Programm 
eingesetzt werden. Wenn Komponenten fehlen, bekommst du bereits beim 
Öffnen des Delphi-Projekts einen Fehler, kompilieren geht dann sowieso 
nicht. Du wirst also gar kein lauffähiges Programm bekommen, wenn 
Komponenten fehlen.

>Könnt ihr mir helfen, wie ich die restlichen Schritte erfüllen kann?

Die Anleitung, wie du diese Komponente installieren musst, hast du doch 
selber gepostet.

Ist das jetzt ein Programm, das du selber geschrieben hast oder hast du 
bloss irgendwo einen Quelltext gefunden den du jetzt im Blindflug, ohne 
tiefere Delphi-Kenntnisse, kompilieren willst?
