in reply to chdir does not work on win2000

Works fine for me - v5.60 (ActiveState build).

chdir ("c:/temp"); exec "dir";
Prints out my temp dir. What kind of problem are you having? What is the error you get back? "Doesn't work" doesn't tell me a lot.

    It works with that function but not in combination with the native windows 2000 browser : getOpenFile Regards, Pieter

      Here comes a standalone sample of the windows 2000 native browser. You will need the Tk module. You will notice the chdir in their and it doesn't produce any error but it also does not change the directory. It always goes back to the last directory browsed too. says Simply use your question

      #!/perl/bin/perl -w # always with warnings on.. use Tk 800.000; use strict; use vars qw/$edaType/; use FileHandle; my $edaType = "Visula"; use Cwd; cadFileSelect(); sub cadFileSelect { my $edaType = shift; my $cadFile = shift; my $TOP = MainWindow->new; $TOP->title("Select a file"); $TOP->geometry("+50+100"); $TOP->configure(-background => lc("aquamarine2")); my $tFrame = $TOP->Frame; my $bFrame = $TOP->Frame; $tFrame->configure(-background => lc("PaleTurquoise")); $bFrame->configure(-background => lc("PaleTurquoise")); my $lab = $tFrame->Label(-text => "Select a file to open: ", -background => "PaleTurquoise", -anchor => 'e'); my $ent = $tFrame->Entry(-width => 50, -textvariable => \$$cadFile, -background => "PaleTurquoise",); my $but = $tFrame->Button(-text => "Browse ...", -background => "PaleTurquoise", -activebackground => "PaleTurquoise", -command => sub { $$cadFile = fileDialog($edaType,$TOP); }); my $quitButton = $bFrame->Button(-text => "Quit", -width => 12, -background => "PaleTurquoise", -activebackground => "PaleTurquoise", -command => sub { $TOP->destroy; # strictly not necessary Tk::exit; }); my $continueButton = $bFrame->Button(-text => "Continue", -width => 12, -background => "PaleTurquoise", -activebackground => "PaleTurquoise", -command => sub { if($$cadFile) { $TOP->destroy; } else { my $ch = $TOP->messageBox('-icon' => 'info', -type => 'OK', -title => 'Information', -message => "Please select $edaTyp +e input file"); } }); Tk::grid($tFrame, -row => 0, -column => 0, -sticky => 'w', -padx => 10, -pady => 10, ); Tk::grid($bFrame, -row => 1, -column => 0, -sticky => 's', -padx => 10, -pady => 10, ); Tk::grid($quitButton, -row => 0, -column => 0, -sticky => 'w', -padx => 10, -pady => 10, ); Tk::grid($continueButton, -row => 0, -column => 1, -sticky => 'w', -padx => 10, -pady => 10, ); Tk::grid($lab, -row => 1, -column => 0, -sticky => 'w', -padx => 10, -pady => 10, ); Tk::grid($ent, -row => 1, -column => 1, -sticky => 'w', -padx => 10, -pady => 10, ); Tk::grid($but, -row => 1, -column => 2, -sticky => 'w', -padx => 10, -pady => 10, ); MainLoop; } sub fileDialog { # # note now receiving more args... # my ($textWidget, $w, $mainWin) = @_; my @types = setFileTypes($edaType); my $file = undef; # Loop until valid selection is made, or user hits "Cancel" while(not defined($file)) { my $_pwd = getcwd(); chdir("c:\\tmp") or print STDERR "\n\tERROR in chdir: $!\n"; $file = $w->getOpenFile(-filetypes => \@types); if(defined($file) && $file ne '') { return $file; chdir($_pwd); #back to orig dir } else { my $ch = $w->messageBox('-icon' => 'error', -type => 'OKCancel', -title => 'Message', -message => "Please select a $edaType input file") +; if($ch eq "cancel") { $w->destroy; chdir($_pwd); #back to orig dir return $ch; } } } return $file; } sub setFileTypes { my $edaType = shift; return (["Visula Cadif file", '*'], ["Visula Cadif file", 'cadif.file'] ) if($edaType eq "Visula"); # ..........etc. # ...and in case something is very wrong, and edatype doesn't match... return undef; }
        The first time that I ran this, I received an error message when I hit the browse button, "ERROR in chdir: No such file or directory" .. this is because by default it looks like it is hitting "c:\\tmp" - I changed this to "c:\\temp", tried again, and did not receive the error. While browsing I can navigate to different folders etc no problem and see all of their contents. To me that sounds like it is working.

        This isn't a problem with chdir, it appears to be a problem specific to directory named "tmp". If I try to chdir to a directory that doesn't exist, then the "Browse" button shows me files in the working directory of the script. If I successfully chdir, then it shows me files in that directory. But on both of those cases, if the directory name is "tmp", then I am instead shown files in the "My Documents" folder. Sounds like just the kind of thing Microsoft would do.

        An aside: If you cancel out of the Browse window, you get a two-button dialog box that either throws you back into the Browse window or exits the program. You really should allow the user to cancel the Browse window and return to the original form in case they change their mind about browsing.
