File dialogue saving as .csv (file name predefined)

[Horizon]

Hello,

I'm struggling a bit with the file dialogue when saving an .csv file. In a nut shell I'll be putting the program output into a string and saved it in .csv format.
I've simplified the example code below:

[ExportCSV]

'Output as .csv

   r$ = "MyFileName"
   myString$ = "Hello, You"

   csv$ = ".csv"

   filedialog "Save As...", r$, fileName$ 'Where r$ is the desired file name (if I change r$ to "*.csv" the file type is correct but the file name disappears?).

   if fileName$<>"" then

       open fileName$+csv$ for output as #f 'added the extension here so that it saves as the right file type (.csv)

       print #f, myString$

       close #f

   else

   notice "File not saved!"

   end if



I found it necessary to add the .csv extension (csv$) so that when you do save as a file it's applied, but then the file type becomes generic in the filedialogue?


It would be nice if the bottom of the file dialogue window appeared like this:


File name:        MyFileName.csv
Save as type:    *.csv Files

I'm probably missing something obvious, but a point in the right direction would be appreciated

Add the .csv to the filename when you open the file dialog forget about the *.csv that allows all .csv files to be seen rather than your specific filename.csv To be a bit clearer, if you have already chosen the file name why bother with filedialog. you might check if the file exists and offer a warning or pop up the filedialog in that special case, to offer a name change.

Hello Rod,

I see your point. I can always apply the extension to the file open dialogue. Thanks for the advice.
