    MMsystem and Joystick

    I see that the best option is from winsoft components but i don't want to pay for a free program. I think the best way is to write a new one from the scratch.

    MMsystem and Joystick

    Thank you remy i'll check it out. Btw do you know any good components or header for joystick either mmsystem or DInput or Xinput... Thank you again

    MMsystem and Joystick

    Thank you very much now i have the x and y for one time Now how can i handle x and y every time the program is on. Is it a good practice to put a timer and every x seconds runs the MyOnMoveHandler ?

LastJoyX := LocX; LastJoyY := LocY; end; end. i know how to activate it and how to setup in the right port That i cant handle is how to get the move option the unit have so i create a var myJoy : Tjoystick; begin myJoy := Tjoystick.Create(form1); myJoy.OnJoyMove <---- that how can i handle? end; thank you
  6. Hello, I am using the default ClientRest components the provide the Delphi Community 10.3.2. I manage to get and delete a file from a json server but i can't do a post. I try to post a new user to cscart based jsonserver here is the api wiki that tells how to manipulate the API. https://docs.cs-cart.com/latest/developer_guide/api/entities/users.html I don't know how to post the data needed for creation a user. Thank you.

    dbExpress "database unavailable"

    After many tries and a lot of read i found that the dbExpress components simple aren't to stable. So i change to FireDac and everything works just fine. So please do not use dbExpress components at least for Interbase Database embedded. Thank you for all the awnsers.

    dbExpress "database unavailable"

    Hello.. I finally manage to success a TSQLConnection with all the required params. Before i run my program i test it and change the connection from false to true. Add the password and it connects successfully. Return to True to False propertie. Try to run my program and i get the below message Am i doing something wrong or embarcadero have some default about dbexpress components and make me drive crazy?

    FMX Tstringgrid

    Ok i found it the right one is csCart.main.Grid.InsertObject(vi, TStringColumn.Create(csCart.main.Grid));
  12. azrael_11

    FMX Tstringgrid

    Try to add columns to Tstringgrid at run time with the code below var vStringColumn: TStringColumn; for vi := 0 to 15 do begin csCart.main.Grid.InsertObject(vi, TStringColumn.Create(vStringColumn)); ... end; But i get abstract error ... What i am doing wrong? I use Delphi 10.3.2
  13. azrael_11

    TStringGrid maybe problem

    I download and install successfully the new 10.3.2 Delphi CE Start a new VCL program Add a Stringgrid and load some data inside. Every ok in that stage. When i try to click inside the grid or in the column or everywhere inside the stringgrid i get the forbitten icon and i can't do anything. Did i miss something here or is a bug to new CE edition?
