Locfile() on top - Foxpro?

I have a PRG which runs a top-level form. In the PRG I want to use locfile() to create a reference to a file which will be used in the form. How can I force the locfile() dialog to come up on top?

The application is a COM server (EXE), which is run from a C++ application. When I run it the locfile comes up hidden behind the Calling EXE.

LOCFILE() is not what you should use, if you want a file dialog. LOCFILE() only falls back to using a dialog as last resort, if it doesn't find a file. Use GETFILE().

GETFILE() has no default folder, but LOCFILE() has, so that's why I prefer LOCFILE(). However the problem with not being on top is the same.

Interesting,
a) CD into the desired default folder and GETFILE starts there.
b) GETFILE uses the system open file dialog, which should appear on top always.

You might set the alwaysontop=.f. when your form is started and right before you start LOCFILE or GETFILE.

Bye, Olaf.

a) I prefer not to change the default folder, but of course it is possible...
b) Unfortunately it does not appear on top

No form is started - I run the file open dialog from the main PRG.

My conclusion is that I need to involve a form to force it on top.

You initially said "I have a PRG which runs a top-level form". You also said "In the PRG I want to use locfile() to create a reference to a file which will be used in the form"

You didn't made very clear what you do when, but GETFILE and LOCFILE should display their dialog on top no matter if a VFP form already is shown or not.

You also said "The application is a COM server (EXE)", then you'll have an olepublic class to start it from C++. How about showing your code?

Here's what I tested:
Define Class myclass as custom olepublic
   somefile = ""

   Procedure init()   
      somefile = LocFile("C:\temp\test.txt")
      somefile = GetFile("txt")
   EndProc 
EndDefine

Open in new window

Compiled into myapp.exe and registered by compilation.

Started from Word via:
Dim o As Object
   Set o = CreateObject("myapp.myclass")

Open in new window


This displays both dialogs in front if the word document. I'd say you have to figure out where Windows stores defaults/last usage and positioning of the system file open dialog, this is at least not a general misbehaviour of VFP.

Bye, Olaf.

The solution is correct, but does not solve my problem. I had to move the opendialog from the prg to a form, then it works.
