It was the assert error. Your update has fixed it.

Re: WeatherFax...

This is probably not the right thread for this problem, but here goes.

I can find weatherfaxdialog.cpp line 230. How did you determine it was line 230 of weatherfaxdialog.cpp? I have run debug a number of times and this line does not highlight, popup or show up in any way. When wx error comes up, hit Yes, it stops at a some appbase.cpp (break into the debugger) document every time it seems and can't get to the line of code.

I tried Options and changing just a few things but extraneous output resulted, so I turned those off again. First screen shot.

I tried searching through various windows. Autos, Locals, Threads, Modules, Watch1, Find Results. Most were empty although Locals has show items with breakpoints but leads to no code file.

Have also been looking at Call Stack, Breakpoints, Error List and Outpot which also don't seem to lead anywhere. Next screen shot.

Have done a search on "go up the debug stack" and it is inconclusive, don't know how to find the line that caused the crash. Has crashed a number of times. Any suggestions? Perhaps a little more description of how you "go up the call stack" would help. Do I run Opencpn until the wx warning, then pick set breakpoint, then step through Debug until it crashes, or do I pick Continue, and go into Opencpn and just continue opening the weatherfax until it crashes?

  1. What settings and windows should I be looking at?
  2. After a crash is there a way to run it backwards to find the error in the code file and line?
  3. How do I get to see each line in weatherfaxdialogue as it executes (steppiing through debug) and then see the breakpoint or failure line?

I would like to help with debugging but what I am doing now is not very helpful. Is this something I should just give up on?

Re: WeatherFax...

In weatherfaxdialog.cpp I right clicked and picked Go to Dissasembly. Don't know if
void weatherfaxdialogue :: whitestransparency changed (wxscrollevent) means anything

Is there a way to show the line number? can't find that setting.

Re: WeatherFax...

Ok from there I highlight the line and right-click and pick "Go to source code" and I get this window.

There is no line number, how do I get that to show?

I still don't know if this is finding the problem code, but there was something happening to transparency because the weatherfax window was broken up with it loaded after selecting the file.

A little more verbose help figuring this out would be appreciated! Thanks.

Re: WeatherFax...

git cloned weatherfax_pi, built debug and release versions,
tried release version and it seemed to work, but there is still a transparency problem or interference anomyly when the fax is opened and then when you go into edit.
The fax does show on the chart which is an improvement over previous version, where it bombed with wx errors etc.

I note the changes to layout to increase area of fax in progress. Looks good.

Click on capture message "Failed to set up stuff. Works only on linux"
Work in progress.

Transparency sliders & invert seem to work

Tried Polar
1. Colored Coordinate Lines work nicely need to give blow by blow description for user or they won't know how to do it.
A. Pick Get Mapping
B. Select vertical meridian toward pole, on a latitude.
C. Select latitude away from pole.
D. Set coordinates
E. Apply - Maybe moves over to be an action like "Finish"? Then Finish

I get an error checking saying "Resulting image has negative dimensions abborting, which is nice checking, because my coords are not right. Cant seem to get it to take and redraww on chart. Maybe have an option to "Force this" so user can see what is happening so he can change it.
Stilll would likke a magnifier if possible.

Like the checks in Weatherfax window for on and off, nice.

Have to mess with this more later.

Re: WeatherFax...

Ok one more try with a diffferent polar file.

Got the blue circular lines to roughly align by hitting "Get Mapping" again, before that the blue circles remained offset and screwy. Perhaps I don't have the longitude right but that should not matter really. I'll put in -34 and see if it works. Close but no cigar.

Re: WeatherFax...

rgleason

Look at your post #189 where you posted a screen shot of the wxAssertFailure. That was the call stack. Look for the last non-wxWidget call. You will see WeatherFaxDialog line 230.

The same call stack is displayed in the Visual C++ debugger. Just click on the entry to go to the source code and line.

Re: WeatherFax...

Dear Chuck,
I'll look at the popup closer next time!!! Maybe I won't have to upload so many images then!!! Maybe I will get the hang of it now. Thanks.

Got it to fail. See the entries after wx and lines. Should have written them down, but how do I get MSVC++debugger to display the call stack?
I think that is my problem.. Thanks for you help.

Go to tools. Then settings. Select "Expert Settings".

Re: WeatherFax...

Thank you Chuck!

Sean, see the bottom of How to use a Sextant
Index Error
"Index error is an instrumental error. When looking through a sextant at the horizon the exact level horizon will seldom be seen to be at 0"

It also has listed:
Index
Dip
Refraction
Parallax
Semi-diameter

Re: WeatherFax...

One of the "Tools > Setting > Expert Settings" that I did not try. Sean, for you:

CALL STACK
weatherfax_pi.dll!EditFaxWizard::OnPaintImage(wxPa intEvent & event) Line 1042 + 0x78 bytes C++

SUBJECT LINE 1042
wxBitmap bmp(GetCurrentPage() == m_pages[0] ? m_wfimg.m_phasedimg : m_wfimg.m_mappedimg);

Trying to get Polar fax set up. I have it close enough (very) with blue circles pretty darn close, and have been trying to get it to take. Each time I select apply
(a number of times) Click on Apply "Resulting image has negative dimensions aborting."

WHAT IS True width ratio with Value=-1.#IO
Is this correct?

Thank you Chuck

I will not be attaching screen shots as often now.
