Sure.    Go to the IDE you want the file loaded to and give last focus to it then do your double click business. Most users would want IDE last worked in to get incoming files.  Note not tested across Desktops!     

 

 

Maybe misunderstood what i write or i write completely wrong.

Let me be more specific.

function Tfrm_custom_debug_info.RunCommand(Command: String): Boolean;
var
  full: string;
begin
  full := '/C '+ Command;
  ShellExecute(0, nil, 'cmd.exe', PChar(full) , nil, SW_HIDE);
  Self.Close;
end;

I have this function in my code.

the command which is string is the full path of a .pas file.

when the program is in runtime and run this function the .pas file opens in the last Delphi IDE i open.

What i want to do here is.

1. Get a list of all DELPHI IDE that running
2. Somehow when i execute the function above open the .pas file in the DELPHI IDE i want choose from the list i get above.

I think now be more specific.

Thank you

If you double-click on a file in Windows Explorer that is the active application, so if you have more than one Delphi instance running none of them is active and which one is handed the file probably depends on which one the BDSLauncher app registered as "server" for .pas files finds first. You have no control over that, so do not open the file by double-click, drag it to the IDE instance you want to use to open it.

The main reason to seek which Delphi IDE have the "control" to open files is not the double clicking. Is that when i am inside the project i made when i open a form then i get the class name and make with a key compination like ctrl+F1 to open the .pas file of the form.

But when i have two Delphi IDEs open i cant sent it to open in the specific IDE to open instead that it opens in the last instance of Delphi IDE.

Is there anyway to open this file at runtime from the specific Delphi IDE that i want and not the last one that opens?

Thank you.

How can i take a list of opened Delphi IDE and which one is the active when i do a double click in a .pas file?

Hello...

I install the Intraweb 14

and when i open Delphi 10.4 i get this error

Can someone tell me how to fix this.

Thank you,

Download K_Lite_Codec pack and install. Either of the three variants will work.

 

Be certain you have:  OpenDialog1->Filter = TMediaCodecManager::GetFilterString(); 

included.

After 2 year ago and i have found no solution ... always get " unsupported media file "

 I would suggest saving the TForm itself rather than each of its child components individually.

I think this is the best way. Thanks

Based to this Implementing Object Persistence using Streams i think i manage to save all the runtime created components of my form in a dat file.

with this code when the form closes

procedure TForm.FormClose(Sender: TObject; var Action: TCloseAction);
var
  strm: TFileStream;
  vi: integer;
begin
  strm := TFileStream.Create('MyComponentList.txt', fmCreate);
  for vi := 0 to ComponentCount - 1 do
    strm.WriteComponent(Components[vi]);
  strm.Free;
end;

Now how can i load all the components in FormCreate or In FormShow event.

In tutorial can read-load a component by its name.

So how can i get the name of all components in the dat file so i can read-load?

Hi

I am totally new to android development with delphi.

I success to setup and deploy a simple program in my device.

Now try to create a folder in Documents folder ->storage->0->Documents->myProject and put images and text files in it.

But i dont know how.

Any simple examples.

And one more question how can i find if the Documents folder exists.

Thank you

Thank you very much for all the help.

If you have and html sites to read about md5 or sha1 or crc i appreciate.

Hello

I download an image from the internet and the author gives me the

sha1, md5 and crc or the image to check if the download image is correct.

1. Can i take somehow the sha1 or md5 or crc of the downloaded image with delphi.

2. Can i do this with Turbo LockBox components. And if i can a simple example how to do this or a web site to explain.

3. Can i add different sha1 or md5 or crc in the same image

Thank you

This may be worth exploring:
https://torry.net/quicksearchd.php?String=joystick&Title=Yes

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.

Then you are just going to have to debug the code at runtime to find out what is really happening.  The OnJoyMove event is fired by an internal TTimer that calls joyGetPos() at regular intervals and then compares the latest coordinates and button states for any changes from the previous call.  The fact that you get the OnJoyMove event fired at least once means the timer is running and polling correctly.  So either you are doing something to block that timer from firing again, or maybe you are deactivating the TJoystick without realizing it, or maybe joyGetPos() itself is failing.  We can't debug for you, because we can't see your real code.

 

FWIW, manually polling the hardware at regular intervals is not the best way to go.  Makes me wonder why TJoystick was not written from the beginning to use joySetCapture() instead to allow the OS to send its own event notifications to the app.

No, this is likely not related to FMX at all - unless FMX TTimer is broken.

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

No. The event OnJoyMove should triggered every time you move the joystick, not just one time. There must be something else.

Yes it triggered only one time  hmmm

Is there a change to have problem that i use FMX platform.

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 ?

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

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.

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.

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?

Best with an admin tool (IBExpert, DataBase Workbench, DBeaver, ...) or per Code/ORM.

The Rest doesn't differ much from other databases and depend on the access library used.

 

Thank you Markus

Do you know any good links for very beginner in Interbase

Like how to create a database

Ok i found it the right one is

 csCart.main.Grid.InsertObject(vi, TStringColumn.Create(csCart.main.Grid));

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

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?
