Here is a New compiled windows version?

Thanks so much for taking the time to help!

Yes I noticed you already fixed the null pointer bug in Dash.cxx. I hadn't pay much attention to that when merging - my bad. I had assumed it was just extra gauges which I used Dash.fl to add back in (Dash.cxx is auto generated from Dash.fl via fluid.exe) - didn't notice there were code changes as well at first.

Time to merge again...

 

OK here is the merged source code. Note: The binary (exe file) is Cygwin, not Windows version!

The wait() and Fl::flush etc. are added back in and the null pointer bug is fixed.

Update: I tried to compile with FLTK 1.3.0 and to my surprise it made a difference. Before with FLTK 1.1.10 the main control window does not show. Now with 1.3.0 all windows show but clicking on buttons inside window does not work - at most sometimes the corresponding menu would show up partially, as if the response is very very sluggish: essentially the same behavior as SteveDH's exe file running on my 2 different laptops. By the way this is with VC++ 2010 Express which seems to behave the same as 2008.

Another update: compiled with MT as opposed to MTd, no difference.

More update: move boost from 1.44 up to 1.47. No difference.

I wonder if somehow the Sleep( ) function is slowing down everything (it shouldn't). Take a look here:

I am using two laptops, one 32 bit XP professional SP2 with VC++ 2008 Express and the other 64 bit Win 7 professional SP1 with VC++ 2010 Express. Both run the example programs from FLTK without any problem. Now I wonder if the threads somehow got locked up for some reason. The only common programs that's running on both machines I can think of: Windows Explorer, Notepad++, Firefox, Beyond Compare, VC++ & NetBeans IDE. One has Symantec Endpoint Protection and the other Microsoft Security Essentials. I will try quit other programs.

Update: tried quitting as many programs and background processes as possible. Still got non-responsive windows.

 

My Windows version would not run with VC++2010 it would only run with VC++2008. I also have SP3 on a very old IBM600E runnig XP home. My biggest problem is lack of hard drive space 6gb.

 

SteveDH compiled with VC 2008 so if we just use his compiled exe file then we need VC 2008 redistributable. I am compiling with 2008 on one machine and 2010 on another. Both gave the same problems.

A small step forward: I tried to use the VC debugger to see whether the threads got hung up. It seems that when I pause the debugger some of the threads always stop at the Fl::lock() added by SteveDH and marked with "#define VC_WIN". So I tried removing the VC_WIN from the preprocessor definition and now the main control window is responsive and I can exit the program normally! But the gauges and license windows are now blank. Tomorrow I will experiment with turning on and off various statements under the "define VC_WIN".

 

Well not much progress yet. Either I keep the extra code:

Code:

#ifdef VC_W
                    Fl::lock();
#endif
#ifdef VC_W
                    wait(0.01);
                    MSG wMsg;
                    BOOL bRet;
                    while (bRet = PeekMessage( &wMsg, NULL, 0, 0, PM_REMOVE))
                    {
                        TranslateMessage(&wMsg); 
                        DispatchMessage(&wMsg); 
                    }
#endif
#ifdef VC_W
                    Fl::unlock();
#endif

and get all windows showing their content but being non-responsive, or if I remove the code then I get only the main control window showing its content and being responsive but the other windows being blank.

For those of you who run the Windows version successfully, do you see the PriiDash icon (see example in my signature banner below or avatar picture to the left) showing at the upper left corner of each window?

 

It finally worked! I kept all of SteveDH's extra code.

The problem was that if I didn't click on the green button "Accept License", then other windows became non-responsive. This "feature" definitely wasn't intended but may be nice to have after all.

Once I click on the "Accept License" button and the "About" window closes, everything works fine. I haven't tried with OBD-USB hardware yet but at least the simulation mode runs fine and I can easily adjust or enter user parameters in the main control window.

Thanks a million to SteveDH again for making the Windows version work!

Now the only thing is the PriiDash icon doesn't show in the windows, unlike the CygWin version.

 

One thing that surprised me was when I compared the loop speed in the simulation mode between the native Windows version and the CygWin version, the native version was slower! I did the comparison on a laptop and a netbook. Both gave the same trend. Weird.

 

I just uploaded Windows (VC2010) version here:

http://sourceforge.net/projects/priidash/

Sometimes it gives errors but on my commute home today it worked fine for the entire trip of almost an hour.

The CPU usage is lower than the CygWin version but the screen update seems slower too. The RPM dial jumps as opposed to smoothly swings. Not sure why.

Update: Looked in the csv file and found that all the passive messages come in only about 1/2 as frequently (Windows vs. CygWin version). I knew there was one place where the Windows version had an extra delay but I didn't expect so much difference. I will be experimenting taking that delay out and see.

 

Tried removing the delay and not much difference. Then I tried Ubuntu. Interestingly the data comes in about 3% more frequently than CygWin. So I guess the bottom line is that not all data is collected - when the PC is busy doing other things some data got lost. (We knew that since at least every 0.2 second we stop listening and send in a query for non-passive data. We just didn't expect large difference between operating systems.) CygWin and Ubuntu are getting similar data rate as Vass got in his setup. Windows gets about 1/2.

By the way new version just came out:

Update: Thanks to Ian MacArthur, Greg Ercolano, and Albrecht Schlosser from the FLTK general discussion group, the FLTK usage of the program has been improved a lot and now the Windows native version (developed with MinGW) performs as well as the Cygwin version. I will post the new version on SourceForge soon.

 

Done!
