delphi - GetDir in Delphi2010 not working under Windows 7? -

-

i have following sequence of commands in delphi2010:

  var netdir:string;   ....   opendialog1.initialdir:=netdir;   ....   opendialog1.execute...   ....   getdir(0,netdir);   ....

after executing opendialog should have in string netdir directory finished opendialog.execute. , in next opendialog.execute should start directory. works fine on xp, not on windows 7? starts directory program installed.

any idea might wrong?

thanks.

your question cannot answered stands, because lacks several crucial details.

  1. is netdir global constant, or go out of scope every , then?
  2. do set netdir prior opendialog1.execute?
  3. is question directory getdir return (as title suggests), or how make open dialog remember last visited directory (as body matter suggests)?

i assume 1) netdir global constant, 2) not set initially, , 3) want open dialog remember last visited folder. have like

unit unit3;  interface  uses   windows, messages, sysutils, variants, classes, graphics, controls, forms,   dialogs;  type   tform3 = class(tform)     opendialog1: topendialog;     procedure formclick(sender: tobject);   private     { private declarations }   public     { public declarations }   end;  var   form3: tform3;  var   netdir: string;  implementation  {$r *.dfm}  procedure tform3.formclick(sender: tobject); begin   opendialog1.initialdir := netdir;   opendialog1.execute;   getdir(0, netdir); end;  end.

then solution let windows remember directory you, is, do

procedure tform3.formclick(sender: tobject); begin   opendialog1.execute; end;

alone! why doesn't method work? well, getdir doesn't return want. if need explicit control, do

procedure tform3.formclick(sender: tobject); begin   opendialog1.initialdir := netdir;   opendialog1.execute;   netdir := extractfilepath(opendialog1.filename) end;

C#: Application without a window or taskbar item (background app) that can still use Console.WriteLine() -

i'm trying create application adheres following: no taskbar no console or form window can utilize console.writeline() . (i.e. if executes app command prompt write console.) the problem if create windows form (or wpf) application can have there no taskbar, console or window show up, console.writeline() nothing. if create console app, writes console, can't figure out how hide (and if did hide it, write command prompt window?)... how do this? just create standard console application. callers responsibility hide window caused program (from how run c# console application console hidden ): system.diagnostics.processstartinfo start = new system.diagnostics.processstartinfo(); start.filename = dir + @"\myprocesstostart.exe"; start.windowstyle = system.diagnostics.processwindowstyle.hidden;

i'm trying load particular private key encoded in binary der format ( pkcs#8 ) ruby. however, openssl::pkey won't recognize it. can make work doing console work , transforming pem so: openssl pkcs8 -inform der -in file.key -passin pass:xxxxxxxx >private_key.pem after this, key can correctly read. however, since whole process done in memory instead of writing , reading files. so question is: possible load private keys binary encoded der format ruby/openssl? thank time, fernando yes, can indirectly load pkcs#8 der-encoded private keys using ruby openssl. openssl::pkey::rsa.new handle pem-formatted pkcs#8, easy read binary der , convert pem-formatted string , load string. for example, these der-encoded private keys: $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -nocrypt -out pkcs8.key $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -v2 des3 -passout pass:secret -out pkcs8_des3.key you can this: require 'open...
