Dennis,
OK, OK, my bad. You see my previous comment was not
intended to be taken so seriously.
I have very different perspective than you and others on the
list
since C++ compiler is my everyday bread and butter so I have
very different expectations and very different opinion than
majority.
If I wrote so on some "hard core C geek" forum, I would be understood
better.
Apparently 2008 "express" version is less
restrictive
compared to previous 2005. I am not using 2008. Three years
ago I bought Professional Edition 2005 to find that I use
it only for 64 bit compilations because it is slow for
everyday work, crashes a lot and code produced is not compatible with
9x windows.
I use good old version 6 (from 1997 afair) because it is
fast and compatible with all Windows versions. That old
version 6.0 is
something that Microsoft has done very well (but there was
no free editions at that time).
Best
regards,
Tomasz Janeczko

Express simple DLL sample file?
Tomasz,
While, being a Mac guy, I am quick to vilify Microsoft.
However, in this case you are being too harsh on them. They seem
to have improved their free version for 2008 and with some more
experimentation, I was able to get the free version to compile the ADK Sample
project and produce the sample.dll. Then I modified the functions.cpp
slightly and made another sample.dll that functioned properly with AFL
calls.
Here is what I did to make it work:
1. I reinstalled the ADK from scratch to get rid of my previous
experiments.
2. I double clicked the Sample.dsp file which launched Visual C++
2008 Express Edition
3. A dialog box came up requesting to convert the project format
to an updated version --I clicked Yes. This was the key step.
4. I did a "Build Solution" from the Build menu.
5. The Sample.dll was generated error free and placed in the
"Debug" folder.
6. I moved the Sample.dll into the Plugins folder and started up
AmiBroker. I added a plot calling ExampleEMA. Success.
There is a humorous side to this story also...
I modified the ExampleEMA just to make sure that it was my changes that I
was seeing and not something else, since the ExampleEMA was a prebuilt
function. I called it myExampleEMA, and I changed the function to return
a constant. It worked half way???? The name changed, but it
returned the exact same moving average result as before.
I tried all kinds of changes to that function which seemed to have no
effect. I finally commented practically everything out in the
function and it still returned a beautiful moving average. My mind was
going in circles tying to figure out how my changes could be
ignored. It truly seemed impossible. It is funny that
when you don't know what you are doing and in a new situation, the mind is
open to the wildest speculations to explain what is happening.
Eventually, I commented out the other two functions: exampleMACD and
ExampleMA. Finally I got a compile error message. It turns out
that there is a typo in the function table. Both ExampleEMA and
ExampleMA point to VExampleMA code. Since the file was last modified in
2001, it must have been there for 7 years and nobody noticed until now --or at
least did not bother tell AmiBroker about it. It was lurking for all
those years just waiting for a novice like me to get tricked into thinking the
laws of programming physics were suddenly altered. LOL
Now I will proceed to try and make my real dll work.
Best regards,
Dennis

Hello,
Visual C++ 2008 EXPRESS edition (FREE) is severely
limited and does NOT support creating of DLLs at all.
That's why you get error when compiling it with Express
edition.
Microsoft never gives useful things for free. Express
editions are toys only.
To create DLLs you need either Standard or Professional
edition, or free Borland compiler or free GCC( GNU CC)/MinGW
Sample project files for free Dec-C++ are included in
the ADK.

Tomasz

Paul, That is exactly what my plan was and what
I was attempting to do. However, the example in the ADK would not
compile error free with Visual C++ 2008 Express as I explained.
Perhaps it would with the full version, but I explained that issue
in my last post to Mike.

Hello,
I took the challenge from Tomasz that anyone who is
willing to learn,
can extend AFL to do
anything. My chosen task is to restore the
scroll position of the
Parameters Window after a "Reset all" button
click --and yes, it has
an important use.
Tomasz informed me that I would need to
write a DLL to make this
possible. There may be
other ways, but I will try it this way.
First I have to say
that I do not know C++ (other than AFL has a
similar syntax). Next I
am not very familiar with anything Windows (I
am a Mac guy). So if I
can do this (with a little help from my AB
friends) Tomasz will be
vindicated in his statements.
I determined that all I need is
to make an extremely simple DLL. It
will create the
following new AFL function:
oldScrollPosition =
GetSetWindowScroll(newScrollPosition);
It will
simply return the current scroll position of the active
foreground window and
then set the scroll position to the supplied
parameter. It should
only be about 10 lines of C++ code.
I have found the Windows
calls that will get the handle of the
foreground window, and
(with a pointer from Tomasz) calls to get and
set the scroll thumb
position on a standard window.
Everything else I need to do I
can handle with AutoIt or AFL.
I have installed the free ADK
and installed the free Visual C++ 2008
Express program, and
started to try to write this.
Initially I tried just Building
the Sample DLL in the ADK. That
mostly works, but gives
me errors on the Plugin.cpp:
error C2491: on 5 critical lines
for : Definition of dllimport
function not
allowed
these are the PLUGINAPI statements for Release,
Init,
GetFunnctionTable,
SetSiteInterface, and GetPluginInfo.
Somehow, I think I
really need these lines to compile for any AB DLL
to work...
I
have tried a bunch of things, and I can make it give me more
errors,
but
unfortunately no less errors. So I think I need some hints or
more help to get
started.
I was wondering if anyone has an answer, or a simple
DLL sample
project
file that builds error free on Visual C++ 2008 Express that
you could email me to
get me started on the right track with
this?
Thanks,
Dennis
