I am running ShellExecute(0, 'open', 'ms-paint:', PChar(FilePath), nil, SW_SHOWNORMAL) , Paint 3D is open but the file is missing ??? , with mspaint is working or other painting program What is the correct command ??? Thank you Vagelis Bekyros

Thanks that is working

procedure OpenImageWithPaint3D(const FilePath: string); var StartupInfo: TStartupInfo; ProcessInfo: TProcessInformation; AppName: string; CreateOK: Boolean; begin // ShellExecute(0, 'open', 'ms-paint:', PChar(FilePath +' /ForceBootstrapPaint3D'), nil, SW_SHOWNORMAL); // ShellExecute(0, 'open', 'mspaint', PChar(FilePath), nil, SW_SHOWNORMAL); AppName := 'mspaint'; ZeroMemory(@StartupInfo, SizeOf(TStartupInfo)); StartupInfo.cb := SizeOf(TStartupInfo); StartupInfo.dwFlags := STARTF_USESHOWWINDOW; StartupInfo.wShowWindow := SW_SHOWNORMAL; CreateOK := CreateProcess(nil, PChar(AppName + ' ' + FilePath), nil, nil, False, 0, nil, nil, StartupInfo, ProcessInfo); if CreateOK then begin // Successfully created the process CloseHandle(ProcessInfo.hThread); CloseHandle(ProcessInfo.hProcess); end else begin // Failed to create the process MsgInformation('Failed to open the file with Paint 3D.'); end; end; This function is working for mspaint Paint 3D is a modern app, which doesn't use executables like older classic applications. With var AppName what i use ????

I am trying to write on ini file with Delphi Alexandria 11.3 on MacBook Pro ,everything is working except I can't write to ini, the read option is working fine my ini file [Server] Server=192.168.1.103 Database=postgres Schema=lis Port=5432 IdleTime=90 Username=nikos Baseurl= DicomID=1 Upload=PgTools Connection= server:= Settings.ReadString('Server','Server','localhost'); Schema:= Settings.ReadString('Server','Schema','lis'); port:= Settings.ReadString('Server','port','5432'); database:=Settings.ReadString('Server','database','postgres'); all variables are reading Server section but when i try Settings.WriteString('Server','Username',Common.CurrentUser); Settings.WriteString('Server','Connection',DateTimetostr(NOW)); Nothing is happen i have give permissions read/write to the Pgtools,ini file For example, this code is working TFile.WriteAllText(TPath.GetHomePath() + TPath.DirectorySeparatorChar + 'Sample.txt', 'Hi over there for current user '); Any Idea

Hi thank for answer the only way working is read and write options are two different approaches , each time you have to free your TInifle var when you switch between read and write when using MacOS platform

Ok Thank you

here is my in Splah Unit unit Splash; interface uses System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants, FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs,Common,rCommon, FMX.Objects, FMX.Edit, FMX.Controls.Presentation, FMX.StdCtrls,Inifiles,System.IOUtils; type TSplashform = class(TForm) SplashImage: TImage; Label1: TLabel; Label2: TLabel; lprogram2: TLabel; lprogram: TLabel; passwordedit: TEdit; usernameedit: TEdit; Backrect: TRectangle; procedure usernameeditKeyDown(Sender: TObject; var Key: Word; var KeyChar: Char; Shift: TShiftState); procedure passwordeditKeyDown(Sender: TObject; var Key: Word; var KeyChar: Char; Shift: TShiftState); procedure FormDestroy(Sender: TObject); procedure FormCreate(Sender: TObject); procedure FormShow(Sender: TObject); private server,Schema,port,database, conectstr,apath:string; Settings: TIniFile; public { Public declarations } end; var Splashform: TSplashform; implementation {$R *.fmx} uses mdata,fMain,System.DateUtils; procedure TSplashform.FormCreate(Sender: TObject); begin //PgTools:=Tstringlist.Create; apath:= TPath.Combine(TPath.GetDirectoryName(ParamStr(0)), 'Pgtools.ini'); {$IF Defined(MACOS) } apath:= StringReplace( apath,'MacOS','Resources/Startup',[rfReplaceAll, rfIgnoreCase]); {$ENDIF} Settings:= TIniFile.Create(apath); end; procedure TSplashform.FormDestroy(Sender: TObject); begin if Settings<> nil then Settings.Free; end; procedure TSplashform.FormShow(Sender: TObject); begin lprogram.text:=rCommon.sLogoprogram+' current version '+common.OraCurrentVersion; usernameedit.Text:=Settings.ReadString('Server','Username',''); end; procedure TSplashform.passwordeditKeyDown(Sender: TObject; var Key: Word; var KeyChar: Char; Shift: TShiftState); // var // s1,s2:string; begin if key=vkReturn then Begin server:= Settings.ReadString('Server','Server','localhost'); Schema:= Settings.ReadString('Server','Schema','lis'); port:= Settings.ReadString('Server','port','5432'); database:=Settings.ReadString('Server','database','postgres'); conectstr:=format(common.Connectstr,[server,database,Schema]) ; with dataform do Begin LisConnection.Port:=port.ToInteger; LisConnection.ConnectString:=conectstr; try LisConnection.Open; Mainform.ServerLb.Text:=format(rCommon.sUserConnection,[usernameedit.Text]); Mainform.ServerLb.FontColor:= TAlphaColorRec.Green; Common.CurrentUser:=usernameedit.Text; if Settings<> nil then Settings.Free; Settings:= TIniFile.Create(apath); try Settings.WriteString('Server','Username',Common.CurrentUser); Settings.WriteString('Server','Connection',DateToISO8601(NOW)); finally Settings.Free; end; Except On E:EXception do Mainform.ServerLb.Text:=E.Message; end; close; End; End; end; procedure TSplashform.usernameeditKeyDown(Sender: TObject; var Key: Word; var KeyChar: Char; Shift: TShiftState); begin if Key = vkReturn then begin passwordedit.SetFocus end; end; end.

here is the code without free server:= Settings.ReadString('Server','Server','localhost'); Schema:= Settings.ReadString('Server','Schema','lis'); port:= Settings.ReadString('Server','port','5432'); database:=Settings.ReadString('Server','database','postgres'); conectstr:=format(common.Connectstr,[server,database,Schema]) ; with dataform do Begin LisConnection.Port:=port.ToInteger; LisConnection.ConnectString:=conectstr; try LisConnection.Open; Mainform.ServerLb.Text:=format(rCommon.sUserConnection,[usernameedit.Text]); Mainform.ServerLb.FontColor:= TAlphaColorRec.Green; Common.CurrentUser:=usernameedit.Text; // if Settings<> nil then Settings.Free; // Settings:= TIniFile.Create(apath); // try Settings.WriteString('Server','Username',Common.CurrentUser); Settings.WriteString('Server','Connection',DateToISO8601(NOW)); // finally // Settings.Free; // end; Except On E:EXception do Mainform.ServerLb.Text:=E.Message; end; close; End; and the results from ini file without freeing and with freeing Connection= CurrentDatetime

Can Anyone share information about how to use a report Generator (Fast report or R Builder) inside a Context . Mars library is grate with many many samples inside , but for reporting (a very important issue on web applications) has no any example (The Author of Mars Mr Andrea Magni can help us how to start reporting with FastReport or RBuilder). Thank You Vagelis Bekyros

Thank you David the problem was not the path i free the Settings: TIniFile before a write to the sections if Settings<> nil then Settings.Free; Settings:= TIniFile.Create(apath); try Settings.WriteString('Server','Username',Common.CurrentUser); Settings.WriteString('Server','Connection',DateToISO8601(NOW)); finally Settings.Free; end; Now is working as you see

How to check is on Delphi Delphi deployment or on MacBook Pro Why this is workig TFile.WriteAllText(TPath.GetHomePath() + TPath.DirectorySeparatorChar + 'Sample.txt', 'Hi over there for current user '); on the same directory i see new file 'Sample.txt'

Hi David This is simple FMX Splash form (login form) before user start working with connected database (Postgres using Devart PgDac Components for Connection) All the init connections strings are stored in Pgtools.ini file on directory programs is running , but when deploy on MacOS i change the path as you see my project here is my code attached files , running on windows write settings is working. On MacBook Pro the software is running OK , logging is successfully after reading Pgtools.ini file settings (Cannot write) Splash.fmx Splash.pas

Hi am new Onomnithread library , and i examine the TwoFish example i understand how Working Schedule works , My question is how can i restart the FWorker.Schedule if database is not connected (for example unstable network) after a few seconds until database be connected ??? In the main thread a create an instance of TComclass procedure TMainform.Button1Click(Sender: TObject); begin acom:= TComclass.Create(nil); acom.OpenConnection(format(common.PostgresConnection,['wwwwwwwww','wwwwwwwwww','wwww']), procedure (Sender: TObject; FatalException: Exception) begin if assigned(FatalException) then Begin if FatalException is EDAerror then Begin if (FatalException as EDAerror).ErrorCode=0 then Errormessage.Caption:=FatalException.message else Errormessage.Caption:=FatalException.message+inttostr((FatalException as EDAerror).ErrorCode); End else Errormessage.Caption:=FatalException.message; // ShowMessage('Failed to connect to the database! ' + FatalException.Message) end else Begin Errormessage.Caption:='ComServer database connected' ; End; end); end; Declaration of Tcomlass procedure TComclass.OpenConnection(const databaseName: string; onConnectionOpen: TNotify); begin FWorker.Schedule( FWorker.CreateWorkItem(databaseName), FWorker.Config.OnExecute(ConnectToDatabase).OnRequestDone( procedure (const Sender: IOmniBackgroundWorker; const workItem: IOmniWorkItem) begin if assigned(onConnectionOpen) then Begin onConnectionOpen(Self, workItem.FatalException); if workItem.IsExceptional then Begin fdataModule.lisconnection.ConnectString := workItem.Data.AsString; fdataModule.lisconnection.Connected := true; end; end; end )); end; procedure TComclass.ConnectToDatabase(const workItem: IOmniWorkItem); var dataModule: TdmComdb; begin dataModule := (workItem.TaskState.AsObject as TdmComdb); dmComdblock.Acquire; //probably only necessary when using InterBase driver dataModule.lisconnection.ConnectString := workItem.Data.AsString; dataModule.lisconnection.Connected := true; try finally dmComdblock.Release; end; end;

Any one knows a good DICOM (Digital Imaging and Communications in Medicine) library doe Delphi.There are a few Chinese libraries but they totally missing documentation and support
