Hi !

If a  menu bar is activated in an Oracle form  version 4.5.7.1.6 I would like an .exe program to run in an own process.
I am working in NT4.0.
I start the program with host(system_command_string);
but you have to close the program to get back to the form.
I would like it to run at the same time.
Is it possible ?

The host command is more for running a command.
Use the DDE Package to run a concurrent application:

DECLARE
   AppID PLS_INTEGER;
BEGIN
   AppID := DDE.App_Begin('C:Prog.exe',DDE.APP_MODE_NORMAL);
END;

You can also use functions like DDE.App_End to end the app.
See Online Help for more details.

The ORA-106500 message means that it cannot find the program you have told it to start.  Make sure you either use the full path, or that the program exists in a directory that is listed in you DOS path.

for example
AppID := DDE.App_Begin('c:\windows\notepad.exe',DDE.APP_MODE_NORMAL);
AppID := DDE.App_Begin('notepad.exe',DDE.APP_MODE_NORMAL);
would both work OK but
AppID := DDE.App_Begin('c:\notepad.exe',DDE.APP_MODE_NORMAL);
gives the ORA-106500 error.

It works BUT I can't open the aplication with argument.
If I try from the command prompt:
c:\temp\Ides.exe -username my_user -password my_user connect_string mydatabas

it works but if I try that in the formprocedure

App.ID:=DDE.APP_BEGIN('c:\temp\Ides.exe -username my_user -password my_user connect_string mydatabas',DDE.APP_MODE_NORMAL);

it doesen't work. Does the package function add any garbage sign .
