Hi,

The code below (WHEN_BUTTON_PRESSED trigger)is supposed to create a group of applications and display their short cuts on the screen but it does not seem to be working.

declare
	
	channel_id pls_integer;
	
begin
	if
		:global.channel_id is not null then
		channel_id := to_number(:global.channel_id);
		dde.execute(channel_id, '[creategroup(Chapter 27))]',1000);
		
		dde.execute(channel_id, '[additem(winword c:\Program Files\Microsoft Office\
		office11\template.doc, Letter Template,c:\Program Files\Microsoft Office\
		office11\winword.exe, ,30, ,c:\Program Files\Microsoft Office\office11\]',1000);
		
		dde.execute(channel_id, '[additem(f50run32.exe e:\inv_sys\test.fmb, Forms & Excel,f50run32.exe
		, ,110, ,e:\Oracle_developer_suit\bin]',1000) ;
		
		dde.execute(channel_id, '[additem(f50run32.exe e:\inv_sys\test1.fmb, Forms & Word,f50run32.exe
		, ,190, ,e:\Oracle_developer_suit\bin]',1000) ;
		
		dde.execute(channel_id, '[showgroup(Chapter 27,1)]',1000);
		
	else
		message('A communication channel must be established first. ');
	end if;
	
end;

I can see this comment at the bottom

FRM-40735 WHEN_BUTTON_PRESSED trigger raised unhandled exception ORA-106555

On searching the forum I got answers on using excel and encountering this error but nothing on PROGRAM MANAGER (windows shell program)

Can you figure out the reason why? I am also not aware what will be the substitute for the f50run32.exe this is supposed to be the icon source file but I could not find it in the developer home, please let me know if you have any idea.

Place 'message();pause;' pairs between each statement to determine which one is giving rise to the error.

Thanks for the response..

I tried putting message();pause; in between sentences but did not help.

message() must have a message to print and PAUSE suspends processing until the end user presses a function key. PAUSE might display an alert.

I tried message() which gave an error then tried message('') along with pause; but it did not display any alert or message that will give me an idea about the error.

Have I used it in a wrong way?

declare
	
	channel_id pls_integer;
	
begin
	if
		:global.channel_id is not null then
		channel_id := to_number(:global.channel_id);
		dde.execute(channel_id, '[creategroup(Chapter 27))]',1000);
           message('');
           pause;		

		dde.execute(channel_id, '[additem(winword c:\Program Files\Microsoft Office\
		office11\template.doc, Letter Template,c:\Program Files\Microsoft Office\
		office11\winword.exe, ,30, ,c:\Program Files\Microsoft Office\office11\]',1000);
		
           message('');
           pause;	

		dde.execute(channel_id, '[additem(f50run32.exe e:\inv_sys\test.fmb, Forms & Excel,f50run32.exe
		, ,110, ,e:\Oracle_developer_suit\bin]',1000) ;

           message('');
           pause;	
		
		dde.execute(channel_id, '[additem(f50run32.exe e:\inv_sys\test1.fmb, Forms & Word,f50run32.exe
		, ,190, ,e:\Oracle_developer_suit\bin]',1000) ;
		
           message('');
           pause;	

		dde.execute(channel_id, '[showgroup(Chapter 27,1)]',1000);
		
           message('');
           pause;	

	else
		message('A communication channel must be established first. ');
	end if;
	
end;

Aaahhh!!! Put a REAL piece of text in the message!!! For example, 'line 1', 'line 2', 'line 3', THEN you can see which line is about to be executed or has just been executed.
