    Use the Win32 SHFileOperation() API to copy the file with the FOF_RENAMEONCOLLISION flag:

     If you need to know what the copied filename was renamed to, include the FOF_WANTMAPPINGHANDLE flag as well:

    Alternatively, on Windows Vista+, you can use the IFileOperation API instead, using IFileOperation.SetOperationFlags() to set the FOF_RENAMEONCOLLISION flag, IFileOperation.CopyItem() and IFileOperation.PerformOperations() to perform the copy, and if needed use an IFileOperationProgressSink event sink to discover the copied filename in the PostCopyItem event.

    Thanks Remy for your help!!!

    You cannot delete a file that is in use, unless the app that is using the file explicitly permits the deletion (by specifying FILE_SHARE_DELETE when opening the file). Nobody does that under normal usage, so you will need to detect when this condition happens (check GetLastError() when the deletion fails) and then. either 1) retry the deletion later or 2) ask Windows to delete the file on the next reboot (via MoveFileEx(MOVEFILE_DELAY_UNTIL_REBOOT)).

    You are right force deleting a file is not a good idea. The other (unknown for me) process needs the file. Any idea if there is an API to add a kind of duplication number like: file (1).txt, file (2).txt, file (3).txt ? 

    I did Google something but I did not find 1-2-3 an API for that. Anybody knows?

    You should check GetLastError to see the reason why it fails. https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-deletefile

     

    One of the possible reason is that the file doesn't exists and the other is that the file is in use by other application.

    Thanks and agree! I had to check if the file exists. But the DeleteFile() call was recently added. In previous versions of my app it failed on the next statement TFIle.Copy().  So again; is there a way to force delete a file? 


  4. Hi!

     

    I need to copy a file to the Windows-temp folder. But on some of my clients it fails. I can not reproduce it, but when they open a mail with attachment in Outlook and my app is working on the same filename it fails. The routine below fails.

     

    Please do not focus on Outlook, but in general. How can I 'force delete' a file? Or how can I safe save a file to the temp folder without problems? Any suggestions? Please help!  

    -Emile

    function TdtmBoot.CopyFileToTempFolder(const AFullFileName: TFileName): string;
    begin
      var lFileName: string := ExtractFileName(AFullFileName);
      var lTempFolderFullFileName: string := GetTempFolder + lFileName;
    
      try
        if DeleteFile(lTempFolderFullFileName) = False then; // @17.22
        begin
          SendMadBugReport(Self, 'CopyFileToTempFolder(), delete failed');  // <<<<<<<< HERE IT FAILS!!!!!!!
        end;
      except
      end;
    
      Result := lTempFolderFullFileName;
      try
        TFile.Copy(AFullFileName, lTempFolderFullFileName, true); // true = overwrite
        Result := lTempFolderFullFileName;
      except
      end;
    end;

    Delphi suffers from lack of popularity and thus lack of adequate funding.

    Too many things at once (mac, linux, mobile, fmx, vcl, c++ builder).
    Ideally, it would be as if the company would choose some one way and focus all attention and power on it, increasing quality and performance. 
    Delphi needs:

    - Roadmap back!
    - Make finally 64 bit IDE, compiler, linker etc. with total abandon of 32 bit(do not wasting time on 32 bit version and focus on one)
    - performance (yes it matters all the time)
    - Improve the quality and speed of bug patching (it's a little better than e.g. 5 years ago, but it's still outrageously slow comparing e.g. to VStudio, where we get some update, hotfix etc. every few weeks.

    - Realise that developers need quality much more than new features (they don't understand it for over 25 years)

     

     

    Agree! Hotfixes and/or faster updates would be nice. Good quality goes above new features!

    The C# library Raptorious.Finance.Swift.Mt940 has been ported 5 years ago to .NET core at  https://github.com/mjebrahimi/SharpMt940Lib.Core/tree/master 

     

    I have used the raptorious one to successfully parse ABN AMRO MT940 files and convert them to CD at https://github.com/jpluimers/MT940-to-CSV

     

    It should be relatively straightforward to port them to Delphi.

    Thanks!

    I managed to loop with ControlCount.

     

    First I disable all controls on my panel.

    Then I enable my PageControl.

    And as last I loop all mu controls on my PageControl and set them disabled.

    
                // SET ALL COMPONENTS TO READONLY
                  // Disable first all components
                  for I := 0 to RzPanel1.ControlCount - 1 do
                    RzPanel1.Controls[I].Enabled := False;
                  // Enable TabSheets
                  PageControl1.Enabled := True;
                  // Disable components in PageControl
                  for I := 0 to PageControl1.ControlCount - 1 do
                    PageControl1.Controls[I].Enabled := False;

    Thanks for the help and hints.

    Use GetControls() new since Delphi 11 I believe. Just as an example for me to disable TcxEdit's only. But you can do your own stuff:

    for var ctrl in frmMain.GetControls([ceftAll]) do
        begin
          if (ctrl is TcxEdit) then
          begin
            TcxEdit( ctrl).Enabled := false;
          end;
        end;

  8. Hi guys!

    I am using D12. I have lots of code for ID’s like this:

     

    type TProductID = record

      ID : nativeint;

    end;

     

    What I want is this:

    type TProductID = nativeint;

     

    And yes I know the last declaration works! But when you make a call to a procedure and you mixed the params by mistake you got no error. Is there any helper, record attribute, compiler directive or so where I did not think of?!?!

     

    procedure TForm6.FormCreate(Sender: TObject);
    begin
      var tmpid: TProductID := 6;
      AddToStock(tmpid, 100);
      AddToStock(100, tmpid);  // I want a compiler warning or error here!!!!!!!
    end;

    procedure TForm6.AddToStock(pid: TProductID; cnt: nativeint);  // Both uses internally nativeint
    begin
      ShowMessage(pid.ToString);
    end;

     

    Now I have lot's(!) of database code like this in my program....

     

    var cid : TCustomerID;

    var pid: TProductID;

    pid.ID := qryGetStockProductID.AsInteger;

    cid.ID := qryGetStocCustID.AsInteger;

     

    What I want is:

    pid:= qryGetStockProductID.AsInteger;

    cid := qryGetStocCustID.AsInteger;

     


  9. Hi!

     

    I installed ICS 9.1 today, wowww I am impressed. The demos are very impressive, compliments to the author(s) 😉 But also overwhelming with so much functionality. 

     

    Can you give me a direction where to look for with what is the easiest way to find a MySQL server ( with port 3306 open) on my LAN (192.168.x.x)? 

     

    Thanks in advance, Emile

    In forward declaration of a class, compiler immediatelly knows the size of that type. For records, their size would be unknown in forward declaration.

    That can be true, but that is 'not my problem' how to solve it. I use records a lot for several reasons (speed, memory management,....). And it would be VERY nice to have that.

    All components that have the form as Owner (which includes all components dropped on the form in the IDE designer) are automatically destroyed when the form is destroyed. So your query components are destroyed but whether that automatically releases serverside resources depends on how the component, especially its destructor, is implemented. But a TFDQuery will close the query when it is destroyed, so your scenario is OK.

    Thanks for the quick reply!!  😉

    I don't need any new features.

    I just need that the existing features work as intended. And there are many areas where existing features need to be made usable again (e.g. refactoring, code formatting, HighDPI).

     

    OK, one new feature would be nice: compiling for Raspberry Pi. But fixing the existing features needs to be done first.

    Totally agree. Fix the existing things first....

    Outlook's contact info is a vcard file and calendar event is vcalendar *.vcs or *.ics file. The employee calendar shows the events provided by the calendars the employee has access to. 


    Example of email attachment
    https://answers.microsoft.com/en-us/outlook_com/forum/all/how-to-insert-attachment-to-recurring-meeting 

    You would simply add an event attachment to the email of employee.

     

    But better to educate the office staff how to use Outlook calendar by having the secretary set the events on the employee calendars as needed. 

    Employee leave requests are sent to office manager. If approved the secretary amends the department's calendar which updates the employee calendar.

    The employee looks at the calendar events provided by the secretary. The secretary knows when the employee knows of a calendar event by the employee opening an email with a calendar event attachment and confirming the event.

      
     

    Thanks for your answer. First the link does not work. And second my application is a planning tool where lots of mutations are done during the day. And adding email with attachments is not a good option ( we tought of that), because there will be a lots of mouse click work than and I don't want to run VBA scripts. Therefore I want full access to the local application, where the secretary has access to xxx employees. And I want to add/remove directly into Outlook. It already works for 1 calendar. But now I want to address one specific calendar.....that is my question

  14. Hi team!

    I have a question; I have a situation where a secretary manages multiple calendars in Outlook. So from her manager, employee 1, employee 2, etc. Is it possible to get access to all calendars of all people? For example I want to put an appointment in the calendar of 'Employee 2' via Delphi 12.

     

    I now use the 'basic' access like:

    try
    
      myOutlook := GetActiveOleObject('Outlook.Application');
    except
    
      myOutlook := CreateOleObject('Outlook.Application');
    
    end;
    
    etc. etc.

    And that works. ( I use it for sending emails ). But I don't know you to use multiple calendars....

     

    Your help would be much appreciated!

    Thanks in advance,
    Emile

    I think it depends on the OS target.

    On Windows, I do not add any file

    On Android, I add lib-native-activity.so

    On MacOs I add libcdsqlite.dylib and libcrypto.dylib

    On IOS I add ... nothing

    On Linux I add ... nothing

     

    But I'm not sure all these libraries concern SQLite

     

    Great! I work only on the Windows platform. One DLL less 😉  So the Embarcadero guys did a translation found on the SQLITE.ORG source code to Delphi-Pascal?
