Hi folks,
VFP 9 SP1 on Windows 7 Ultimate.
I have a process to let the user choose a file. The user opens a .scx
form, presses a button to run some code that calls GETFILE(), and
when the user has done so, the path and file name are displayed on the form.
When I run this form in stand-alone mode, this works fine. GETFILE()
returns the path and file name to a string variable and I then
display the variable contents on the form.
When I run this form from within the full application, GETFILE()
displays the proper location and behaves perfectly fine, but when the
user chooses a file, it always returns an empty string.
I've tracked this in the debugger. In both cases, I emphasize, from
the point the user presses the button, the exact same code runs, at
each point generating the exact same results, until we get past
myvariable = GETFILE(parms)
line, at which point myvariable is empty in application mode, but
contains the full path and file name in stand-alone mode.
I am following the correct procedure to obtain an appropriate full
path, and in both cases the GETFILE() dialog displays the correct
location and is configured properly according to my parameters.
It simply won't return a value when run from inside the application.
I've read everything with "GETFILE" in the subject line in the
leafe.com archives. I can't find anything that addresses this situation.
My application does not use the _SCREEN (SCREEN = OFF in the
config.fpw file). Instead I have my own main window which is modeless
and "2 - as top level". Normally the import window, which is modeless
and (1 - in top level), is called from a modal form that is opened
from a menu item.
To eliminate the possibility that this modal/modeless business is
interfering, I put the button that opens the import form directly on
my main window, so that the only open windows are the modeless
top-level form and the modeless in-top-level import form before the
GETFILE() dialog is called. That's as close as I can get to running
the import form in stand-alone mode. This did not help.
The stand-alone mode of my framework's forms actually creates the
same environment that exists in the full application before opening
the form, so I can't see how not actually running the full
application can make a difference. I emphasize, again, in the
debugger, from the point the user presses that button every single
step runs exactly the same way, and returns the same results, up to
the GETFILE() dialog, in both stand-alone and full-application modes.
My code stores the location that I want GETFILE() to display to a
variable, mypath, so I do:
oldpath = FULLPATH(CURDIR())
CD (JUSTPATH(mypath))
myvariable = GETFILE(parms)
CD (JUSTPATH(oldpath))
Some people suggest using SET DEFAULT TO ..., so I also tried it like this:
oldpath = FULLPATH(CURDIR())
CD (JUSTPATH(mypath))
SET DEFAULT TO (mypath)
myvariable = GETFILE(parms)
CD (JUSTPATH(oldpath))
SET DEFAULT TO (oldpath)
That doesn't help either.
The default is for the file name and path to contain spaces, and this
works just fine in stand-alone mode. But I renamed the test file to
remove spaces, and put the file in C:\foo, so there are no spaces
anywhere in the path or file name, and it still doesn't work full
application mode. GETFILE() just returns an empty string.
I've also tried using PUTFILE() instead of GETFILE(), even though
it's less elegant for my purpose. PUTFILE() also works as I expect in
stand-alone mode but returns an empty string in full-application mode.
LOCFILE() is not an option because I can't mandate a file name for this.
This is driving me absolutely bonkers.
Possibly I could roll my own file dialog, but short of that, can
anyone provide any suggestions to explain why this is happening?
Any suggestions
