Hi All,

I'm trying to figure out why I am suddenly having an issue with the MapPoint ImportData method. I'm currently importing a tab delimited file (it was working in the previous version of my program) and for some reason the method is now giving me the following error...

"No matching method defined for these fields"

I re-ran the previous version of the program and the pushpin map is still working, no errors are being thrown. So I tried the following...

1)I stopped the current version of my program right before the ImportData method is called

2)I renamed the import file about to be imported to filename.old and then took the import file that was created by the old version of the program (the one that opened up a pushpin map without any errors) and gave it the name of the file I just renamed to filename.old.

3)I hit F5 to continue the program and the map displayed without any errors pushpins and all.

Sooo this led me to think the file that causes errors has some formatting issues. So I tried this next.

1)I stopped my program right before the ImportData method is called

2)I opened the import file that causes problems and the import file that works and copied the data from the working file to the file that causes errors. Basically CTRL + A... CTRL + C... CTRL + A... CTRL + V and presto working data overwrited non-working data.

3)I hit F5 and the "No matching method..." error was thrown.

Now I find this odd because when I renamed the working import file to the same name as the error import file the map and pushpins showed up fine but when I replaced the data in the error import file with the data from the working import file I still get an error.

Does anyone have any ideas? Did I explain this well enough?

Thanks in advance for any help.

Hi Mike,

Are you very sure of the delimiters? also the EOL delimiters ? Also the decimal separateor did not change ? Nothing changed in locales of machine ?

Hi Wilfred,

I think I've narrowed it down. It appears that a backend class written by our controls department may have changed how it creates the tab delimited file. If I open the old input file in Ultra Edit the file looks fine but if I open the new file it opens it in Hex and if I turn off the Hex view the file looks kind of screwy so I'm going to have to find out if they've changed anything.

Thanks for the response.

Mike
