PBMap - OSM, Here, Geoserver maps in a Canvas gadget

Thank you for your code and your report, Michael. I'll try this evening.

Michael Vogel> I can't recreate the bug on x86 and x64. I've tried clicking several seconds on normal pbmap application and multiple maps, nothing. Could you give me more details, please ?

@djes: can you or actually I guess any one just test this?

Code:

Case #PB_EventType_RightClick
        Debug "Right click"
        Debug Pixel2Lat(CanvasMouseX)
        Debug Pixel2Lon(CanvasMouseY)

If I click center of the circle in the middle of the map the Lon I get back is the bottom of the canvas I think but its just not matching up with the center of the circle.

The Lat is fine.

Thanks

Hard to find a pattern when the program gets unstable, most often it happens when coordinates are entered manually (0/0 or 52/0) followed by a 'Enter' and then I do one (or some more) double click(s) to move the center point of the map. Another time the crash could be reproduced when entering a location name ("greenwich") instead of the lat/lon coordinates or to enter the location name directly after the coordinates have been entered.

Some other times I can do the same things with no single crash, maybe it depends on how long the cache tiles need to be loaded from the internet (maybe you can try to add a delay into these routines just for a test).

Sorry I can't give you more detailed information at the moment...

Just a small point I would change for the edit gadgets - these three lines of code for selecting the whole text when getting the focus:

Code:

Case #StringLatitude, #StringLongitude
Select EventType()
Case #PB_EventType_Focus
   CompilerIf #PB_Compiler_OS=#PB_OS_Windows
      SendMessage_(GadgetID(Gadget),#EM_SETSEL,0,-1)
   CompilerEndIf
   AddKeyboardShortcut(#Window_0, #PB_Shortcut_Return, #MenuEventLonLatStringEnter)

Ok, thanx for the feedback, I'll test soon.
Don't forget that the project needs contributors, you're welcome !

It seems that compiling with PB 5.62 leads to crash, when compiling with oldest 5.60 is OK. Anybody can confirm ?

I use the PBMap include from March 2018 without problems, when compiling it as part of my GeoWorldEditor with PB5.62

Very strange. I have to investigate ! Maybe next week...

Sorry for the delay, I've missed your post. These functions are not to be used to convert a canvas position, but to convert an internal x, y representation in pixel to lon, lat. If you want the mouse position, just use the GetMouseLon() and GetMouseLat() functions:

Code:

      Case #PB_EventType_RightClick
        Debug "Right click"
        Debug GetMouseLongitude(MapGadget)
        Debug GetMouseLatitude(MapGadget)

All> I don't have any crash since my last windows update... Anyone suffering crashes ?

Last update here, as usual : https://github.com/djes/PBMap/tree/djes

Is this still maintained at all?

It looks very interesting but it randomly crashes when zooming the map in or out.

Hi, nice to see that someone is using it. In fact, there isn't much activity especially because of the lack of users... As pbmap relies on more pb functions, it's essential to know your platform, pb version and some details on the bug.

I am using PBMap everyday

with very slight modifications... And couple other map sources.. Its very nice.. Thanks

Good to know !

On Windows 8.1 x64 / PB 5.70 x86 when moving the map and zooming in/out quite a bit there are constant Invalid Memory Access errors in Procedure GetImageThread(*Tile.Tile)

Usually the compiler gives this line
*Tile\Download = ReceiveHTTPFile(*Tile\URL, *Tile\CacheFile, #PB_HTTP_Asynchronous, #USERAGENT)

or this one
*Tile\Size = FinishHTTP(*Tile\Download)

Tried it on Mac and it also crashes with Invalid Memory Access

Thank you. Have you tried to clear the cache ? Sometimes a malformed/incomplete file can't be replaced on the disk and leads to a crash.
