How Do I Write This Expression Please?

[Annie]

Hi guys. I've been trying to create an Expression for the Save File action of the Edit Box. This is how it works (part of the app):

When user clicks on a line in the Datagrid, then clicks the BUILD button, it generates an item listing based on cell data from the grid. Got that bit working great!

You can then click SAVE button, to save the file (I'm hoping automatically rather than via selector) and have the file named depending on the line selected in the Datagrid. EG: "item1.txt" or "item27.txt" etc.

The expression to use for the PATH to saving the file is confusing me - this is the expression I have currently which doesn't save the file:

(The files are in a sub-directory "ItemDescriptions" of the Application folder)...


Appdrive$+Appdir$+"\ItemDescriptions\item"+Str$(Li neClick( "DataGrid" ))+".txt"

Am I anywhere near close? Or am I chasing a non-succeedable goal here?!

Thanks for any help as usual

It looks pretty good to me..

The Appdrive+appdir bit will place the location exactly in the same folder as the application file. You will then be putting the file into the "\ItemDescriptions\ Folder. The file name will be called item+lineclick.txt.

Seems ok, is it not working?

[Annie]

Nope! I've been double checking everything and it would seem it should work. I've tried it without the sub directory too and no luck there either. Dohhhhhh

Instead of saving make it add the expression to a list box and see what is says.

[JasonDarby]

Yes as Joshtek says, put it into an edit box as what you will find sometimes is an extra \ or something like that which stops it from working correctly.

The other option if possible is to upload the example and we can take a look at it.

Thanks

Hmmm. Well now I know you don't need the "\" preceeding the subdirectory, as it adds one automatically. If you have the backslash, it makes TWO backslashes!

BUT, even after fixing that in the Save action, it still doesn't work (I had my hopes up!).

Anyway, the entire path is correct, I even copy/pasted the resulting string into WinExplorer to be sure! It just won't SAVE the darn file. :-S

[JasonDarby]

Can you upload an example, or email me it?

Thanks

Jason

[Annie]

Email is on it's way, thanks Jason

[Annie]

OH, hi Josh, thanks for your idea, sorry was too busy reading and thought it was Jason again, LOL. Only just noticed Jason's post after yours too, I must have not refreshed before replying to your post... that I thought was Jason's... bedtime almost I think ;-o

Interesting, it looks like its working for me?

You click on the build button, and then save, and i look in the itemdescriptions folder and there is a item1, item2 etc text file.

Perhaps ive misunderstood the problem?
