1. Re: Restore conventional legend layout

Figured it out... Went into the c:\users\xxx\AppData\Roaming\MapWindow folder and deleted MapWindowDock.config. When I re-ran MW, it created a new copy of the file using the default panel locations. I will put an entry into the bug tracker.

2. Restore conventional legend layout

Somehow I've changed the position of the legend and toolbox on the MW screen (MW 64-bit, 4.8.6.22757), and I want to return it to its conventional location on the left side of the screen. How do I do that -- there does not seem to be any way to drag-and-drop the legend.

4. Re: 4.8.6 - Map projections not working

Paul You win the genius prize! Installing as Administrator did the trick. Now when I look at the properties of various projections, they all have values in the different dialog boxes. Reprojecting the original file into BC Albers worked properly. I can *run* MW as either Administrator or standard user, and it works properly. It was the installation as Administrator that made the difference.

5. Re: 4.8.6 - Map projections not working

Paul -- some progress... installed fresh onto another computer, and it works properly. So back to the original computer. Deleted the MW application and deleted the SVN folder. Used an "uninstaller" program to clean up the remnants of the MW installation. Then went thru the Registry and deleted a large number (~40-50) entries that pointed to MapWindow. Re-installed the MW application

6. Re: 4.8.6 - Map projections not working

Paul Thanks for the clarification. I did not understand about it grabbing the Proj4 library information. Now to your shapefile. You have a shapefile with data from a GPS receiver. This data is in WGS84 (EPSG: 4326). If the projection form shows the EPSG code it is properly recognized. The other fields however should not be empty. *** that is where the problem starts - everything e

7. Re: 4.8.6 - Map projections not working

Paul Tried one more thing -- and I may be off-base here but it seems like data are missing from the Projections database... Downloaded and installed an SQLite viewer, and opened the Projections.db3 file in the MapWindow\Projections folder. Then opened the Dialects table. There were only 6 entries in the table. Should there be at least one entry for each Dialect (just guessing!) Jack

Paul I will try, but not sure if I am doing this correctly. I did not fully understand your instructions. Here are the steps I've carried out. 1 Open the .prj file, and copy the entire string to the windows clipboard 2. Open the shapefile. MW states that it is currently in WGS84 projection. That corresponds correctly with the origin of the file -- it should be plain lat/long data from a

9. 4.8.6 - Map projections not working

Trying to reproject a shapefile using MW 4.8.6. Regardless of which projection I select, it always responds with a message "failed to initialize the selected projection". When I right-click the projection (e.g.NAD83/BC Albers) and choose Properties, the resulting dialog box is mainly empty (e.g. Scope, Proj4, and Remarks). I get the same results when using the latest version from SVN

10. Re: 48RC3 stopped working - stuck!

Paul Now that 4.8.5 is running, I also figured out the issue with the symbol sizing. I had invoked a classification based on a table attribute. Then I went to the Appearance tab and tried to change the size. It would not change. But once I pressed the Clear button on the Classification tab, and then pressed Apply, the proper size was applied. Subsequent Classifications used the proper symbol

Paul I also have an SVN installation running on this computer. Haven't updated in many months. It ran OK - version 4.8.3. So I updated it now, and it runs OK. Version 4.8.5 Unless it is useful to you and the MW project for me to resolve the issue with 4.8.4, I think my best course of action is to just use the SVN version. Jack

Resetting the defaults did not make any difference. When MW is trying to launch, there is a splash screen that displays some progress. It completes the "loading application plug-ins" phase, but crashes on the "loading plug-ins" phase. Thanks for looking into it, Paul. Jack

13. Re: 48RC3 stopped working - stuck!

FWIW - I had also been trying to modify the size of the symbols used for a point shapefile when MW crashed originally. Nothing I could do in the Layer Properties would change the size of the symbol. In other words, I entered a new size for the Point symbol in the Layers Properties dialog, but it would not change on the map. Now, having just re-installed RC2, its version of the symbol size entr

I had been using 48RC3 (4.8.4) on my Win7 Home Premium (32 bit) computer. Was working in the Attribute Table Editor when it suddenly crashed. Now, whenever I try to launch MW, Windows displays a message that the application has stopped working, and must be shut down. Tried several times with complete uninstall and re-install.

16. Re: Fields missing from "Categories" in Layer Properties

May have answered my own question: does the categories only work with numeric fields? Tried adding a new string field to the table; it did not appear in the Categories list. Added a numeric field, and it worked properly. The equivalent functionality in previous MW versions *did* work with string fields, and I expected the same in 4.8.4. Perhaps this capability has been omitted from 4.8.4.

There are about 185000 records, with about 25 fields in the DBF. When its opened in the Attribute Table Editor, everything looks OK.

Been looking for an "export to CSV" or equivalent, but haven't been able to find anything. I know that I could write some VBA code to perform this action, but I first want to know i

19. Re: can't open attribute table editor...

What is the error message? Are you on a laptop computer that used to have an external monitor? It's possible for the ATE to open on a (disconnected) external monitor so it fails to appear on the main screen. Solution is to use <Alt> Spacebar, M, arrow keys to move it back onto the main screen.

I guess I don't understand the question -- I use BC albers all the time with MapWindow, and regularly change between UTM or geographic and BC Albers. Only problem that I had was locating the BC Albers configuration within the MW interface. So... is your question about the process for changing projections in general (which is done with the GIS Tools plug-in), or specific problems with the BC Al

MapWindow is limited to creating String, Integer, and Double data types. Other DBF file editors such as DBF Explorer may be more suitable to your needs.

Had a similar issue when I had run MW on a dual-monitor laptop computer, then disconnected the external monitor. MW continued to think that the table editor was "out in space" on the external monitor. Solution was to move the table editor window "blindly" using keyboard commands.: <alt> spacebar M arrow keys to move the window into view. Hope this helps.

27. Re: Creating Shapefiles: Attribute Table

As far as I know, there are no required fields in the attribute table. But there must be a one-to-one correspondence between the number of shapes in the shapefile and the number of records in the attribute table. I am not clear exactly what you are asking, but I am guessing this is it... You created a shapefile and traced the boundaries of some shapes, thus creating an attribute table with, sa

30. Re: hi can someone tell me how to cut out a particular portion in a landuse file

For a typical shapefile Ensure the shapefile editor plug-in is loaded. Ensure the "delete shape" button is enabled by using the Selection pointer to select an arbitrary object. Open the Attribute Table editor Use the query tool in the ATE to select records or select them manually. Click the Delete Shape tool in the MW toolbar to delete the shapes.
