Hello every one
I would like to ask a very small question. what is the code that should be written to open a picture inside the button.
I have already made the button, and the trigger is when push button, what I want is when I click the button it opens a picture in this directory
F:\Amjad\Amjad\amjad\1.jpg

the name of the picture is taken from table1 the colum serial_number

Thank you

Hi I've moved your thread to the Forms section.

Now, as for your question. So you want to invoke an OS command to show a picture My best bet (It's been a long time since I've used Forms) is to use WEB.SHOW_DOCUMENT(<full path to the image>). Note that the webserver running your Forms needs to be able to access this path.

Sorry
and thanks

well,
I'm sorry Sir,
Maybe I didn't explain my question well. So, I created a button in oracle 6i developer.
Created a trigger, when button pressed
so, what I want is, when I click the button, it opens a picture in this directory for example :
F:\Amjad\Amjad\amjad\1.jpg
look, the name of the image is taken from an item of the block , the block name is My_table1, the item is Serial Number
so it should be,
My_table1.serial_number that refers to the name of the picture

What do you mean when you say "it opens a picture"? In an image item? In a browser? Most web browsers know how to handle images, so my guess is that web.show_document will work, although I'm not sure whether the path you provide should be known client side or on the IAS side. That is something I need to check.

As you use Forms 6i: is this a client-server application, or is it deployed to web? If client-server, maybe HOST built-in would do the job as well; try to specify image name only (as Maaher said - operating system (Windows, right?) *should* be able to open it that way).

For example (untested - I don't have Forms 6i at all and I don't have ANY Forms available at the moment):

declare
  l_image_name my_table1.serial_number%type;  
begin
  select serial_number
    into l_image_name
    from my_table1
    where rownum = 1;

  -- suppose it looks like "12345.jpg". If not, concatenate '.jpg' to serial number

  host (l_image_name);
end;

do this---simple

READ_IMAGE_FILE('D:\'||:My_table1.serial_number ||'.JPG','JPEG','My_table1.IMAGE4');
------------------------------------------------------------------------------

if you wanna create serial number as well then create serial like this 

WHEN-NEW-BLOCK-INSTANCE 

declare
  a number(7) ;
begin
   select count(*)+1 into :my_table1.serial_number from my_table1;
   :global.a:=:serial_number;
 READ_IMAGE_FILE('D:\'||:My_table1.serial_number ||'.JPG','JPEG','My_table1.IMAGE4');
end;

WHEN-BUTTON-PRESSED

begin
 :global.a := :global.a+1;
    next_record;
 :serial_number := :global.a;
READ_IMAGE_FILE('D:\'||:My_table1.serial_number ||'.JPG','JPEG','My_table1.IMAGE4');
end;

and remember picture name should be 1,2,3... or change according to your requirment

Mughal Cool

Thanks you guys,
well, I am using the Oracle Developer 6i, form builder.
Thanks mughals_king.
But what I want is to open it in another thread not displaying it in an item. Just like when you double click the picture inside the folder. I mean I want it to be opened by the photo viewer of the windows

host('F:\Amjad\Amjad\Amjad\'||:My_table1.serial_number ||'.JPG');
it opens the dos window and then closes it. it doesn't open the picture

I see; how about (MS Windows, eh?)

host('mspaint F:\Amjad\Amjad\Amjad\'||:My_table1.serial_number ||'.JPG');

You might need to tweak it a little bit; I hope MS Paint will be started and - hopefully - open the image. If it does, try with some other image viewer, if you wish.

It tried this :

Declare
my_cmd varchar2(512);
Begin
my_cmd := 'rundll32 shell32,ShellExec_RunDLL '|| 'F:\Amjad\Amjad\amjad\'||:My_table1.serial_number ||'.JPG';
HOST(my_cmd, NO_SCREEN);
End;

and it worked
Thanks to you all
