Excellent! Tks p2k.

Hi Team, Despite my pitiful efforts I have managed to get App Tethering working between two Apps. But, I have a problem. IIUC, the Sender has to be running before the Receiver. Something about establishing a socket This I can't guarantee. 😞 Is there any way to configure App Tethering so it dosn't matter if the Sender or Receiver starts first?? Regards & TIA, Ian

Hi Guys, D11.3.1. This is what I understand att. Feel free to correct me if my understanding is incorrect. 1. If I set FormatSettings with a Country code, i.e. "var FormatSettings := TFormatSettings.Create('en-AU');", then that action will configure the various TFormatSettings properties in SysUtils to the Australian formats. 2. I can then forget about the variable FormatSettings. 3. Having set these properties in SysUtils, whatever Unit has SysUtils will have/use the set properties. 4. Any function/procedure that uses a FormatSettings property will now use the relevant set TFormatSettings property according to the Country/Region code employed in the '.Create()'. Are my understandings correct? Regards & TIA, Ian

Ahhh. Tks for the tip. That was always a/the risk. Won't happen. Tks to all for your inputs and guidance. Regards, Ian

Hi Dalija, Thank you for your input. Appreciated. Have you ever worked with Pacific Islanders? I have been dealing with them for the past 7 years and they can be extremely frustrating. They will do things with their PC just because. Including changing their date & time formats. and in a couple of cases their Region. My Customer wants all the Apps to operate to a standard format, interestingly, to en-AU, despite what the User may have done with his/her PC. I thought this would be a good way to enforce it. Regards, Ian

Hi Team, Win 11, D11.3.1. I am playing around with TFormatsettings and I am using this Emba code.. procedure Test; var str1, str2: string; FS: TFormatSettings; strResult, strFormat: TStringBuilder; begin strResult := TStringBuilder.Create; strFormat := TStringBuilder.Create; FS := TFormatSettings.Create('en-AU'); strFormat.AppendFormat('%s %s', [FS.LongDateFormat, FS.LongTimeFormat]); str1 := FormatDateTime(strFormat.ToString, Now()); strResult.AppendLine('1.'+str1); ShowMessage(FS.NormalizedLocaleName); strResult.AppendLine(FS.NormalizedLocaleName); //A second instance with a different locale (used for comparison) FS := TFormatSettings.Create('ro-RO'); strFormat.Clear; strFormat.AppendFormat('%s %s', [FS.LongDateFormat, FS.LongTimeFormat]); str2 := FormatDateTime(strFormat.ToString, Now()); strResult.AppendLine('2.'+str2); strResult.AppendLine(FS.NormalizedLocaleName); ShowMessage(strResult.ToString); // end; What should FS.NormalizedLocaleName return? Emba Help says a string but I am getting nothing back. Or maybe I am and it is blank. Not expected. Regards & TIA, Ian

Hi p2k, I didn't really know what to expect, although I thought it might be, in my case, Australia.

Hi Team, D11.3.1. Win 11. When I double click on a Delphi file in Windows Explorer, it opens in Delphi IDE in DPI Aware mode. Is there someway to make Windows or Delphi open the IDE in DPI Unaware mode when I double click on a Delphi file fromthe File Explorer? Regards & TIA, Ian

Yup it works, but it isn't perfect, yet. 😉

p2k, I was just experimenting with Formatsettings and came across this that gave me nothing. Ian

Hi Team, D11.3. I have an App that populates the captions of two labels. It all works fine. What I would like to do is make this captions availabe to other Apps rather than regerating them in the other Apps. All the Apps are on a Windows 2012 Server. Multi-User. Some of the Apps may be running via RDP, the same and other Apps may be running via LAN, i.e. called from the Server and running physically on the User's PC. Users are using Win 7 & Win 10 workstations. The generating App may be being used at any time by many Users. The term Message Broker came to my mind and IIRC there was something by one of the inhabitants of this Forum that might be my solution. Can somebody refresh my memory and point me in the correct direction please? Or, alternatives. The simpler the better. 🙂 Regards & TIA, Ian

Hi Team, Thank you for your inputs/suggestions? It seems App Tethering might be an option also. Is there working demo with source of App Tethering? Regards & TIA, Ian

Hi Team, D11.3.1. I have the following function I am trying to get to work.. function GetApplicationInstances(const FileName: string): TArray<string>; var ProcessList: TProcessList; Process: TProcess; i: Integer; begin Result := TArray<string>.Create; ProcessList := TProcessList.Create; try for i := 0 to ProcessList.Count - 1 do begin Process := ProcessList[i]; if Process.FileName = FileName then begin Result.Add(Process.UserName); end; end; finally ProcessList.Free; end; end; I have bothe System.SysUtils and System.Diagnostics in my Uses clause but I am still gettin an 'undeclared identifier' for TProcessList and TProcess. What have I missed please? Regards & TIA, Ian

Solved. I added the count to the function. function GetApplicationInstances(const FileName: string; out Count: Integer): TArray<string>; var ProcessEntry: TProcessEntry32; Snapshot: THandle; ProcessList: TList<string>; begin ProcessList := TList<string>.Create; try Snapshot := CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0); if Snapshot <> INVALID_HANDLE_VALUE then begin ProcessEntry.dwSize := SizeOf(ProcessEntry); if Process32First(Snapshot, ProcessEntry) then begin repeat if (ProcessEntry.szExeFile = FileName) then // Replace with appropriate condition begin ProcessList.Add(ProcessEntry.szExeFile); end; until not Process32Next(Snapshot, ProcessEntry); end; CloseHandle(Snapshot); end; Result := ProcessList.ToArray; Count := ProcessList.Count; finally ProcessList.Free; end; end; Tks Guys. Regards, Ian

OK. Moving on. Using Enums rather than TProcess. function GetApplicationInstances(const FileName: string): TArray<string>; var ProcessEntry : TProcessEntry32; Snapshot : THandle; ProcessList : TList<string>; begin ProcessList := TList<string>.Create(); try Snapshot := CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0); if Snapshot <> INVALID_HANDLE_VALUE then begin ProcessEntry.dwSize := SizeOf(ProcessEntry); if Process32First(Snapshot, ProcessEntry) then begin repeat if (ProcessEntry.szExeFile = FileName) then // Replace with appropriate condition begin ProcessList.Add(ProcessEntry.szExeFile); end; until not Process32Next(Snapshot, ProcessEntry); end; CloseHandle(Snapshot); end; Result := ProcessList.ToArray; finally ProcessList.Free; end; end; I have the following lines. var Instances: TArray<string>; Instances := GetApplicationInstances(sFileName); I can't see a way to get the number of elements in the TArray. I thought "for var i := 0 to TArray(Instances).Count do Memo1.Lines.Add(Instances);" would be a monty, but no. How please?

Hi Team, I found that bit of code and thought it would do the trick. Oh well. What I am try to achieve is a delphi function that when given a full application path/name, return how many instances are in use and who is using them.

Bummer. Any suggestions?

Hi Team, I have ths construct: var GeneralThread := TThread.CreateAnonymousThread(procedure begin // tqServerSessions.Close; // try if TEDBEngineSessionManager(DBSWhoIsOn.Handle).TryLock(1) then begin TEDBEngineSessionManager(DBSWhoIsOn.Handle).Unlock; { Session is not locked and is safe for you to use } tqServerSessions.ExecSQL; end else // Delay for the specified amount of time TThread.Sleep(500); // except ... ... end; // tqServerSessions.Last; // ... ... end); How do I safely loop the Try-Else for x times, and then break out after x times?

Tks Team. All sorted. Regards, Ian

Hi Team, D11.3.1. I have this compression routine. procedure CompressStream(SourceStream: TMemoryStream; DestStream: TMemoryStream); var ZStream : TCompressionStream; begin ZStream := TCompressionStream.Create(clDefault, DestStream); try ZStream.CopyFrom(SourceStream, SourceStream.Size); finally ZStream.Free; end; end; If I have this procedure in my main form it is happy. If I move it to my Function library, I get this.. Why should it be happy in the main form an not in the library? Yes, I have System.ZLib in the uses in both cases Thoughts/suggestions? Regards & TIA, Ian

Hi Lajos, Great call. I found that if I had the System.Zlib after the VCL.Graphics, all is fine. Before and I get the issue. Tks for the assist. Regards, Ian Edit: I didn't need VCL.Graphics in the library anyway. 😉

Hi Remy, Yes, seriously. I don't really understand what goes on in Threads and therefore what you can and can't do. I am still learning about them. p2k, Tks. I will have a look. Tks to both of you. Regards, Ian

Hi Team, I am ostensibly sending a PDF file to a TMemoryStream. How do I test if the TMemoryStream has been 'loaded'? Regards & TIA, Ian
