    Calculation problem

    Albion posted a topic in Python4Delphi

    Good afternoon, I encountered such a problem, when executing a python script, the calculations are not written to the output fields, and therefore cannot go further, since they take values from them. Can anyone tell me what I did wrong?

    Hi all, I'm looking to distribute my android app on play store using Delphi 10.3. I know I should upgrade to Delphi 11, but trying to compile the app in the new version I'm stuck in a number of memory or compilation issues. When on Delphi 10.3 I try to start the project deployment I always get the same error "[PAClient Error] Error: E0002 Missing profile name; use paclient -? For Help". I tried to use various versions of the SDK: I tried 26, 28, 29 and even 30 but nothing. When I compile it in development mode both in debug and in release I can load it on my smartphone with Android 10, while compiling it in Release and Application Store mode I get the error mentioned. Some idea? Thanks in advance

    I am emailed html files that link to a Cisco "Secure Email Encryption Service". I can load the downloaded html into a TEdgeBrowser, manually enter the password, click the button, and access the content using document.innerHTML. I need to be able to get the program to fill in the password and click the submit button. Nothing happens when I execute the code I expect to work. I created the following a test form which uses the same input and button: <form action="https://www.google.com" method="post"> Password: <input name="key1" id="passwordInput1" autocomplete="off" type="password"><br> <input type="submit" "id="text_i18n.authframe.safr.button.openonline" value="Open Online" name="openButton"> </form> I set the password using: document.getElementById("passwordInput1").value = 'mypass' I click the button using: document.querySelector("input[type=submit]").click(); Everything works as expected with my test form but I am unable to accomplish this with the "Secure" form. This is likely because the values are embedded in other elements. The structure is very complex and I am leaving out many table rows and other details. I think I have identified the important elements as shown below: <table id="outerTable" <tbody> <tr> <td id="iframelocation"> <iframe id="authFrame" #document >html> <body> <form> <table class="mainWIndow"> <tbody> <tr> <td id="heightControl" <table> <tbody> <tr> <td> <table id=borderTable"> <tbody> <tr> <td id=passwordEntry1"> <p> <input size="20" maxlength="127" name="key1" id="passwordInput1" placeholder="Secure Email Encryption Service Password" title="Enter your password here" autocomplete="off" type="password" style="width: 100%;"> </input> The button is in <td id="openButtonLocation"> in <td id="buttonContainer" eventually going batck to <tr id=buttonRow", etc. and is defined as: <input type="submit" id="text_i18n.authframe.safr.button.openonline" value="Open Online" name="openButton" onclick="openOnline()" class="btn"> The ExecuteScript seems to only execute one line of javascript so I am not sure how to access the field and the button. What do I need to do differently? I would also like to be able to accomplish this using the types (password and submit) instead of the Id once I get this working. Thanks

    Using Livebindings to link a TDataset to a TListview on the same TForm is fine. But I'm still struggling to find a way to connect a TDataset on a TDataModule and a TListView on a TForm using Livebindings. It seems that both the LiveBindings Wizard and the LiveBindings Designer can only work on a datamodule or a form at a time. Is there a standard way to do that, or it's just not possible? Thanks.

    The FireMonkey Low Code App Wizard works fine on Delphi 11 (in RAD Studio 11). The generated project runs without issue. However, after upgrading to 11.1, whenever I run any generated project by the wizard, I got an error, like this: After using the debugger to trace the error source, I found that when the program runs to this line (in the function TScreenOrientationMonitor.GetScreenOrientation in Model.Types.pas) the error will be raised. Since I'm new to this wizard, can anyone please share any clue with me? Thanks a lot.

You link to SFML dynamically by default and will look for the SFML DLL in your application path. You can also call InitSFML, before any other routine, with a the path to the DLL location. Define SFML_STATIC in SFML.pas to statically link to SFML and the DLL will not have to be included in your application distro. InitSFML will have no effect and you can leave it in your sources so that you can switch between static and dynamic linking during development. uses SysUtils, SFML; var Mode: sfVideoMode; Window: PsfRenderWindow; Event: sfEvent; Music: PsfMusic; begin Mode.Width := 800; Mode.Height := 600; Mode.BitsPerPixel := 32; Window := sfRenderWindow_create(Mode, 'Hello SFML', sfResize or sfClose, nil); Music := sfMusic_createFromFile('arc/audio/music/song01.ogg'); sfMusic_play(Music); while sfRenderWindow_isOpen(Window) = sfTrue do begin while sfRenderWindow_pollEvent(Window, @Event) = sfTrue do begin if Event.kind = sfEvtClosed then sfRenderWindow_close(Window); end; sfRenderWindow_clear(Window, DARKSLATEBROWN); sfRenderWindow_display(Window); end; sfMusic_stop(Music); sfMusic_destroy(Music); sfRenderWindow_destroy(Window); end.

    How to Create a RSA key using CMD by Delphi

    João Bosco posted a topic in VCL

    I'm using the "SSH_Pascal" library and creating an SSH connection via delphi. After a lot of effort I discovered that it is necessary to have your RSA key and your host in this file called "known_hosts" in windows it is usually at: %USERPROFILE% + .ssh\known_hosts To create an RSA key using openSSH via CMD is simple, see the command: ssh-keyscan -t rsa your host There, your RSA key is created. The only difficulty I'm having is getting this RSA via cmd and adding it to the file. the simplest way through cmd would be: ssh-keyscan -t rsa your host > %USERPROFILE% + .ssh\known_hosts To insert the value into the file. But using by delphi is not working. I tried using a function(GIst.Github) to get the DOS output, without success. When it enters This step of the Function WasOK := ReadFile(StdOutPipeRead, Buffer, 255, BytesRead, nil); it hangs It just hangs. I've tried to increase the buffer size but without success, does anyone have any ideas?

    Testing with python

    Albion posted a topic in Python4Delphi

    Good day everyone! I have a question. Perhaps someone has already experienced this. I have a ready-made program on Delphi. And I need to initialize and execute all the functions of this program using a Python script. Is it possible to accomplish this task only with the help of TPytnon components? Without adding memos and other things as shown in the demo programs. Just run the script and get the result. Maybe someone can help with this question. I would be very grateful for any help. Thanks for attention.

    CPas - C for Delphi

    tinyBigGAMES posted a topic in I made this

    Overview What if you were able to load and use C99 sources directly from Delphi? There is a vast quantity of C libraries out there and being able to take advantage of them, without being a pain would be nice. You could even compile a bunch of sources and save them as a library file, then load them back in from disk, a resource or even from a stream. You can get the symbols, map to a C routine, and execute from the Delphi side all from a simple API. Downloads Releases - These are the official release versions. Features Free for commercial use. Allow C integration with Delphi at run-time. Support Windows 64-bit platform. Support for C99. Fast run-time compilation. Can run C sources directly or compile to (.LIB, .EXE, .DLL). Library files can be loaded and used at run-time from a file, a resource or stream. Import symbols directly from a dynamic linked library (.DLL) or module-definition (.DEF) file. You can reference the symbols from Delphi and directly access their value (mapping to a routine and data). Your application can dynamically or statically link to CPas. Direct access to the vast quantity of C99 libraries inside Delphi. Minimum System Requirements Delphi 10 (Win64 target only) FreePascal 3.3.3 (Win64 target only) Microsoft Windows 10, 64-bits 20MB of free hard drive space How to use in Delphi Unzip the archive to a desired location. Add installdir\sources, folder to Delphi's library path so the CPas source files can be found for any project or for a specific project add to its search path. Add installdir\bin, folder to Windows path so that CPas.dll file can be found for any project or place beside project executable. See examples in installdir\examples for more information about usage. You must include CPas.dll in your project distribution when dynamically linked to CPas. See CPAS_STATIC define in the CPas unit file. See installdir\docs for documentation. A Tour of CPas CPas API You access the easy to use API in Delphi from the CPas unit. {.$DEFINE CPAS_STATIC} //<-- define for static distribution type { TCPas } TCPas = type Pointer; { TCPasOutput } TCPasOutput = (cpMemory, cpLib); { TCPasExe } TCPasExe = (cpConsole, cpGUI); { TCPasErrorMessageEvent } TCPasErrorEvent = procedure(aSender: Pointer; const aMsg: WideString); { Misc } function cpVersion: WideString; { State management } function cpNew: TCPas; procedure cpFree(var aCPas: TCPas); procedure cpReset(aCPas: TCPas); { Error handling } procedure cpSetErrorHandler(aCPas: TCPas; aSender: Pointer; aHandler: TCPasErrorEvent); procedure cpGetErrorHandler(aCPas: TCPas; var aSender: Pointer; var aHandler: TCPasErrorEvent); { Preprocessing } procedure cpDefineSymbol(aCPas: TCPas; const aName: WideString; const aValue: WideString); procedure cpUndefineSymbol(aCPas: TCPas; const aName: WideString); function cpAddIncludePath(aCPas: TCPas; const aPath: WideString): Boolean; function cpAddLibraryPath(aCPas: TCPas; const aPath: WideString): Boolean; { Compiling } procedure cpSetOuput(aCPas: TCPas; aOutput: TCPasOutput); function cpGetOutput(aCPas: TCPas): TCPasOutput; procedure cpSetExe(aCPas: TCPas; aExe: TCPasExe); function cpGetExe(aCPas: TCPas): TCPasExe; function cpAddLibrary(aCPas: TCPas; const aName: WideString): Boolean; function cpAddFile(aCPas: TCPas; const aFilename: WideString): Boolean; function cpCompileString(aCPas: TCPas; const aBuffer: string): Boolean; procedure cpAddSymbol(aCPas: TCPas; const aName: WideString; aValue: Pointer); function cpLoadLibFromFile(aCPas: TCPas; const aFilename: WideString): Boolean; function cpLoadLibFromResource(aCPas: TCPas; const aResName: WideString): Boolean; function cpLoadLibFromStream(aCPas: TCPas; aStream: TStream): Boolean; function cpSaveOutputFile(aCPas: TCPas; const aFilename: WideString): Boolean; function cpRelocate(aCPas: TCPas): Boolean; function cpRun(aCPas: TCPas): Boolean; function cpGetSymbol(aCPas: TCPas; const aName: WideString): Pointer; { Stats } procedure cpStartStats(aCPas: TCPas); function cpEndStats(aCPas: TCPas; aShow: Boolean): WideString; If you want CPas to be statically bound to your application, enable the {$CPAS_STATIC} define in the CPas unit. How to use A minimal implementation example: uses System.SysUtils, CPas; var c: TCPas; // CPas error handler procedure ErrorHandler(aSender: Pointer; const aMsg: WideString); begin WriteLn(aMsg); end; begin // create a CPas instance c := cpNew; try // setup the error handler cpSetErrorHandler(c, nil, ErrorHandler); // add source file cpAddFile(cp, 'test1.c'); // link and call main cpRun(cp); finally // destroy CPas instance cpFree(c); end; end.

    Greetings Dear Delphians, Say we have 20 Forms in an App. We use these 6 lines to create 20 Forms at different places. Form1 := TForm1.Create; try Form1.ShowModal; finally Form1.Free; end; When refactoring we can see this is a lot of code duplication and we should encapsulate form creation in a procedure like this. procedure ShowForm ( ThisForm: TCustomForm ) ; begin ThisForm := TCustomForm(ThisFormClass.Create);//?? How to Get Form Class try ThisForm.ShowModal; finally ThisForm.Free; end; end; I only have problem in first line. how to get ThisForm parent class to call it. Is it even possible? If yes then how? What about FMX? Any help or pointer is appreciated. Thanks and stay blessed

    In my Delphi application I select a portion of a wave form for music in a Windows .wav file. I would like to then analyze that selection to produce a frequency spectrum like that in the image below. My objective is to identify the predominant musical pitches in the selection. How can I obtain the amplitude vs. frequency data points for plotting?

    Hi, Using the VirtualTreeView, an error is raised but why ?. I have recreated a minimal sample to reproduce it. Either my coding does an error (more likely), either the component do it. The problem comes when a node is deleted (only when the deleted node has one sibbling with subnodes) from the OnGetImageIndex event. The event is called with an index greater than avalaible nodes. If someone has an idea ? Delphi 11 + VirtualTree for VCL 2021.09. Thanks a lot, Eddy TestVclVT.zip

    TTouchKeyboard layout

    shineworld posted a topic in VCL

    Hi all. I'm on a PC with the Italian language and an Italian true keyboard. In the VCL software, I would like to use the TTouchKeyboard. Is a technical software where I need to force TTouchKeyoard to display US keyboard layout, because chars as [ ] | # etc are mandatory instead of accented èéòàù of specific Italian layout. I've imported the Vcl.Touch.Keyboard.pas in project to add minor graphics changes, which works fine, but I'm not able to understand how to force English layout. I've tried to change CreateKeyboard method to say "use alwyas 'en' but doesn't works. function TCustomTouchKeyboard.CreateKeyboard(const Language: string): Boolean; var Index, RowIndex, ColIndex: Integer; Button: TCustomKeyboardButton; LeftPosition, TopPosition: Integer; KeyboardState: TKeyboardState; KeyboardLayout: TVirtualKeyLayout; Row: TVirtualKeys; FoundCaps: Boolean; _Language: string; begin Result := False; FoundCaps := False; for Index := 0 to FButtons.Count - 1 do FButtons[Index].Free; FButtons.Clear; FDeadKey := VKey(-1, -1); TopPosition := 0; _Language := 'en'; if _Language <> '' then FLanguage := _Language; The result is always: There is a way to force it ?

    Hey guys, so for this program I'm writing I want to check a string grid for empty rows/rows with just spaces in them and then subsequently deleting them to clean the grids up a bit. I made a procedure that reads the fields from a specific table in a DB and into a corresponding string grid. While 13 of the 14 grids I have, read the records like they're supposed to from the DB, one single table doesn't read correctly, it reads the same amount of records again as empty rows when displayed on the grid. For example, let's say I have 3 records in the table in the DB and I read it into the grid, the records display properly but then they add 3 more rows with just spaces in them. My code for this so far: procedure TfrmPuntehou.IncreaseRowCount(grid: TStringGrid); begin //increases rows in grid grid.RowCount:= grid.RowCount+1; end; procedure TfrmPuntehou.WriteToList(tbl: TADOTable;grid:TStringGrid); var Row: Integer; i: Integer; begin tbl.Active:= True; Row := 1; // Populate cells Tbl.First; while not (Tbl.Eof) do begin grid.Cells[0,Row]:= IntToStr(Row); grid.Cells[1,Row]:= tbl.fields[0].AsString; grid.Cells[2,Row]:= tbl.fields[1].AsString; grid.Cells[3,Row]:= tbl.fields[2].AsString; Inc(Row); IncreaseRowCount(grid); Tbl.Next; end; tbl.Active:=false; //what I'm planning to do to alleviate this but I'm not sure to use in the conditions of the if // because if I say grid.Rows[i] = ''/grid.Rows[i] = ' ' then I get an error // for i := 1 to grid.RowCount - 1 do // begin // if () OR () then // begin // grid.Rows[i].Delete; // end; // end; end; Illustration of what I'm talking about: What is supposed to happen: What's happening (the records are inserted correctly, but there are unnecessary rows here for only 3 records. When exported to a CSV the empty rows are filled with spaces"): Thanks in advance for any help on this! Kind Regards PrimeMinister
