Hi,

I try to open new OpenOffice document (in writer),
but I am getting the exception
FRM 40735:WHEN-BUTTON-PRESSED Trigger Raised unhandled Exception ORA - 305500

Please help me to resolve this exception.

my code is as follows in when-button-pressed trigger:

declare

App ole2.obj_type;
oDocument ole2.obj_type;
oDesktop ole2.obj_type;
args1 ole2.list_type;
args2 ole2.list_type;
Args ole2.list_type;

begin

App := ole2.create_obj('com.sun.star.ServiceManager');
args1 := OLE2.CREATE_ARGLIST;
OLE2.ADD_ARG(args1,'com.sun.star.frame.Desktop');
oDesktop := OLE2.INVOKE_OBJ(App,'createInstance',args1);

args2 := OLE2.CREATE_ARGLIST;
OLE2.ADD_ARG(args2,'private:factory/swriter');
OLE2.ADD_ARG(args2,'_blank');
OLE2.ADD_ARG(args2,'0');
OLE2.ADD_ARG(args2,Args);

oDocument := OLE2.INVOKE_OBJ(oDesktop,'loadComponentFromURL',ar gs2);
end;

Maybe i need some components from OpenOffice o be installed at forms?

I am running this on winXP, forms v 6i, OpenOffice 2.2.

I can start Writer using VB Script like this:

'The service manager is always the starting point
'If there is no office running then an office is started up
Set objServiceManager= WScript.CreateObject("com.sun.star.ServiceManager")
'Create the Desktop
Set objDesktop= objServiceManager.createInstance("com.sun.star.frame.Desktop")
'Open a new empty writer document
Dim args()
Set objDocument= objDesktop.loadComponentFromURL("private:factory/swriter",_
"_blank", 0, args)
'Create a text object
Set objText= objDocument.getText
'Create a cursor object
Set objCursor= objText.createTextCursor
'Inserting some Text
objText.insertString objCursor, "The first line in the newly created text document."&_
vbLf, false

and I can start MS Word, MS Excel using:

DECLARE
app OLE2.OBJ_TYPE;
docs OLE2.OBJ_TYPE;
doc OLE2.OBJ_TYPE;
selection OLE2.OBJ_TYPE;
args OLE2.LIST_TYPE;
BEGIN
-- create a new document
app := OLE2.CREATE_OBJ('Word.Application');
OLE2.SET_PROPERTY(app,'Visible',1);
docs := OLE2.GET_OBJ_PROPERTY(app, 'Documents');
doc := OLE2.INVOKE_OBJ(docs, 'add');
selection := OLE2.GET_OBJ_PROPERTY(app, 'Selection');
-- insert data into new document from long item
OLE2.SET_PROPERTY(selection, 'Text', :POLE_TEKSTOWE5);
-- save document as example.doc
args := OLE2.CREATE_ARGLIST;
OLE2.ADD_ARG(args, 'd:\example.doc');
OLE2.INVOKE(doc, 'SaveAs', args);
OLE2.DESTROY_ARGLIST(args);
-- close example.doc
args := OLE2.CREATE_ARGLIST;
OLE2.ADD_ARG(args, 0);
OLE2.INVOKE(doc, 'Close', args);
OLE2.DESTROY_ARGLIST(args);
OLE2.RELEASE_OBJ(selection);
OLE2.RELEASE_OBJ(doc);
OLE2.RELEASE_OBJ(docs);
-- exit MSWord
OLE2.INVOKE(app,'Quit');
end;

But I can't start Writer from Forms Sad

Did anyone find the Solution for this? I am getting the same exception at line:

worksheet := ole2.GET_OBJ_PROPERTY(workbook,'Worksheets',args);

My code is as follows:

DECLARE

PRAGMA exception_INIT (no_file, -302000); 
cell_value varchar2(2000); 


BEGIN 


-- Check the file can be found, if not exception no_file will be raised 
Check_file := TEXT_IO.FOPEN('C:\test.XLS','R'); 
TEXT_IO.FCLOSE(Check_file);

ole2.set_property(application,'Visible','true'); 
workbooks := OLE2.GET_OBJ_PROPERTY(application, 'Workbooks'); 
args := OLE2.CREATE_ARGLIST; 
ole2.add_arg(args,'c:\test.xls'); 
workbook := ole2.GET_OBJ_PROPERTY(workbooks,'Open',args); 
ole2.destroy_arglist(args); 
args := OLE2.CREATE_ARGLIST; 
ole2.add_arg(args,'Sheet1');

ole2.destroy_arglist(args);

args:= ole2.create_arglist; 
ole2.add_arg(args, 1); 
ole2.add_arg(args, 1);

ole2.destroy_arglist(args); 
cell_value :=ole2.get_char_property(cell, 'Value'); 
message(cell_value); 

ole2.invoke(application,'Quit');

ole2.release_obj(cell); 
ole2.release_obj(worksheet); 
ole2.release_obj(worksheets);
ole2.release_obj(workbook); 
ole2.release_obj(workbooks); 
ole2.release_obj(application); 
message('Hi am in safer side'); 

-- ASSIGN RETURN VALUE FROM EXCEL TO Text Field
:Block2.RETURN_VAL := cell_value;


exception 
WHEN no_file THEN 
MESSAGE('file not found.'); 
WHEN OTHERS THEN 
MESSAGE(sqlerrm); 
PAUSE; 
FOR i IN 1 .. tool_err.nerrors LOOP 
MESSAGE(tool_err.message); 
PAUSE; 
tool_err.pop; 
END LOOP; 


END; 




I went through the links Maaher posted, and I tried both INVOKE_OBJ and GET_OBJ_PROPERTY, same exception raised.

Thanks,
Baz

Don't you have to start the 'excel' application first?

Hi David,

The code is already starting excel.

When I run it, Excel opens in a different window and the test.xls file displays normally, but again it is failing or Raising the Exception at:

worksheet := ole2.GET_OBJ_PROPERTY(workbook,'Worksheets',args); 



Thanks,
Baz

I managed to overcome the exception Cool by using the following Code for the "worksheet" section:
worksheet := OLE2.GET_OBJ_PROPERTY(application,'activesheet');
OLE2.SET_PROPERTY(worksheet , 'Value','Sheet1');




instead of:
args := OLE2.CREATE_ARGLIST; 
ole2.add_arg(args,'Sheet1');
 Message('hell 2_1'); 
worksheet := ole2.GET_OBJ_PROPERTY(workbook,'Worksheets',args); 
ole2.destroy_arglist(args);




Now it is working fine but I still have one issue Mad . When I write to the Excel Sheet (Update, make changes) it is Prompting me "TO CONFIRM SAVE CHANGES" before Closing the Workbook. How can I apply the Changes without getting the PROMPT?

The current CLOSING code is (some changes have been applied to Code in Previous Post):
args := OLE2.CREATE_ARGLIST;
OLE2.ADD_ARG(args, 'C:\test.xls');
OLE2.INVOKE(workbook, 'Save', args);
OLE2.DESTROY_ARGLIST(args);
OLE2.INVOKE(workbook,'CLOSE');
ole2.release_obj(cell); 
ole2.release_obj(worksheet); 
ole2.release_obj(worksheets);
ole2.release_obj(workbook); 
ole2.release_obj(workbooks); 

ole2.invoke(application,'Quit'); 
ole2.release_obj(application); 




I want to apply the changes in Excel, Save the Sheet/Workbook, and close it without interrupting my work on the Oracle Forms side, as now it is Waiting for the User's Manual Response to Apply/Not Apply the Changes...

Thanks in advance,
Baz

Hi,
I have same code, but bit different requirement.

All i want to do is "OPEN" the excel file which is on Application server, this excel file has a macro inside it which creates another excel file an populates data from some other excel file which is present in same directory.

So my final code looks like -

DECLARE
application ole2.obj_type;
workbooks ole2.obj_type;
workbook ole2.obj_type;
worksheets OLE2.OBJ_TYPE;
worksheet OLE2.OBJ_TYPE;
cell ole2.obj_type;
args ole2.list_type;
BEGIN
/*Test OLE2 for Opening Excel File*/
application:= ole2.create_obj('Excel.Application');
ole2.set_property(application,'Visible','true');

--workbooks := ole2.invoke_obj(application, 'Workbooks');
workbooks := OLE2.GET_OBJ_PROPERTY(application, 'Workbooks');

-- Open the required workbook
args:= ole2.create_arglist;
ole2.add_arg(args, 'c:\temp_dir\Book2.xls');
--workbook := ole2.invoke_obj(workbooks, 'Open', args);
workbook := ole2.GET_OBJ_PROPERTY(workbooks,'Open',args);
ole2.destroy_arglist(args);

worksheets := ole2.GET_OBJ_PROPERTY(workbook, 'Worksheets');
worksheet := OLE2.GET_OBJ_PROPERTY(application,'activesheet');
OLE2.SET_PROPERTY(worksheet , 'Value','Sheet1');


OLE2.INVOKE(workbook,'CLOSE');
-- Release the OLE2 object handles
ole2.release_obj(workbook);
ole2.release_obj(workbooks);
ole2.invoke(application,'Quit');
ole2.release_obj(application);

End;

But all i can see is that there is no error raised, form executes till end. But then no result EXCEL file is created as it should have been after execution of macro.

I did open the EXCEL file with macro on application server by double clicking it, this way result excel file is created, but not from form? - Any suggestions?

Secondly i can see, EXCEL process created in Task Manager of Application Server, but that process hangs there itself, i cant end that process.

Any help is more than welcome!

Thanks & Regards,
Avinash.

hi Avinash,

I am replying to your post as I have faced further complications with the Same issue again, after I had thought that everything was working fine on my Development Environment (Launching Excel, Enabling Addins Programatically, getting Values populated into the Excel Sheet and then sent back into my Form) running the Form and Excel on my Machine, when moved to Production Environment on the Application Server, then the Macro's for Loading the Addins Failed and thus the Data was not being retrieved to be sent back to Oracle Forms from Excel.

In response to your issues:

Quote:

Same thing happended to me, I believe that the Excel MACRO's when the Excel Sheet is triggered Programatically are NOT WORKING PROPERLY. I agree that when you trigger the Sheet manually, it does the job. In my case, the WORKBOOK_OPEN macro routines are throwing the EXCEPTION.

Quote:

Secondly i can see, EXCEL process created in Task Manager of Application Server, but that process hangs there itself, i cant end that process.



For this, COMMENT OUT worksheets:
--worksheets := ole2.GET_OBJ_PROPERTY(workbook, 'Worksheets'); 
worksheet := OLE2.GET_OBJ_PROPERTY(application,'activesheet');
OLE2.SET_PROPERTY(worksheet , 'Value','Sheet1'); 


ALL the OLE2 objects created must be Destroyed before closing the application otherwise you will keep having the Excel.exe process in the background. (Refer to another POST "How to kill EXCEL.exe from Task Manager from Oracle Forms" in this Forum for more info on this Problem)

Hope that the above helps, please let me know if you can get the FIRST one working as I haven't been able to resolve it yet on the Application Server.

Baz

Was there any workaround you found to tackle this?

HI Avinash,

I gave you the solution for the SECOND Issue that you have (EXCEL.EXE).

As for the MACRO Part, I still don't have a solution to have the Excel Macro's Run when the Excel File is opened Programatically from my Oracle Form. Again this Only worked on my Client Machine and not on the Application server (Have you tried that on your Machine???)

I might have to go with another alternative and NOT Excel when I need to Pull Data from my Data Source which in my case is a NOT a relational Database Historian; and feeding into Oracle Form. That is, Not to use Excel as a Mid-Layer.

My other option is to Create a DLL library and create an External Procedure to Connect to Oracle? I am not sure if this would work. I will let you know

If anyone has a solution/explanation for the Excel Macro's, we would really appreciate his/her assistance.

Regards,
Baz

To run an excel macro, use the following code. The application is the handle to the open application.


ARGS := OLE2.CREATE_ARGLIST;
OLE2.ADD_ARG(args, 'ExactNameOfTheMacro');
OLE2.INVOKE(application,'Run',args);
OLE2.DESTROY_ARGLIST(ARGS);

Thanks BILL,

I even tried this earlier but still this didn't trigger my Macro properly in Excel. Sad

It seems that my Application Server is not Liking any Macro's to Run Programmatically when Called from Oracle FORMS. Once the Excel Sheet is Triggered Manually, the Macro's Run smoothly and do the work.

Baz

hello Baz,

I tried your code on my PC, it works, but at appserver, it raises
no file exception

I use

Forms [32 Bit] Version 10.1.2.0.2 (Production)
Oracle Database 10g Enterprise Edition Release 10.2.0.2.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options

EXCEL 2003

I have no info about version of webutil,
can you give versions of your system or any tip?


How can I make it work this code at appserver?

Hi Jale,

Unfortunately I couldn't get my Excel Macro to Run Programmatically when called from Oracle FORMS on the APPLICATION SERVER.

I was using Oracle DB 9i and Oracle Forms 9i (Forms [32 Bit] Version 9.0.2.9.0)

No File Exception seems to be a different problem related to the File Location.

Hope you can get your Code working fine.

Regards,
Baz

baz, hi again,

I called it no file exception.

Check_file text_io.file_type; 
no_file exception; 
PRAGMA exception_INIT (no_file, -302000); 
cell_value varchar2(2000); 


BEGIN 
-- Check the file can be found, if not exception no_file will be raised 
Check_file := TEXT_IO.FOPEN('C:\test.XLS','R'); 
TEXT_IO.FCLOSE(Check_file); 
Message('hellllllllllooo');


exception 
WHEN no_file THEN 
MESSAGE('file not found.'); 
WHEN OTHERS THEN 
MESSAGE(sqlerrm); 



I found this in form help:

"Some OLE commands work fine in a client/server environment,
as well as in Web deployed applications (on the server),
but when you use WebUtil to enable client side functions,
they do not work.

For example, the following code will work by running OLE as client/server,
in a 3-tier environment, or on the application server: "


In here, ole2 word export code from oracle is written.

"However, when you change this code to use CLIENT_OLE2 (using search-and-replace) it doesn't work.
The following example is code which will convert to CLIENT_OLE2: "


What does it mean?

Thanks for replies..
