Hi Red Penyon
i run the code, and surprisingly, there are two records insertedPls check if u have any pre-insert block level , key-commit , pre-commitTrigger form-level or any Duplicate ; CREATE_RECORD ; Built-in may be u use to add this record.
i Suggest if u remove the message Level from the commit other error messages may be pop up with a reason ...
if not u can Remove the Commit as Anderas Suggested will the record be the one with blob or the one with blob not null value.
or just for tracing purposes u can display a messages with the values of ur forms' items before and after the commit.
MESSAGE (':b2.file_name ' || :b2.file_name);
MESSAGE ('CONTRACT_NO = ' || :IB_LOVE.CONTRACT_NO); .... ETC.COMMIT;
MESSAGE (':b2.file_name ' || :b2.file_name);
MESSAGE ('CONTRACT_NO = ' || :IB_LOVE.CONTRACT_NO); .... ETC.Oracle® Forms Developer WebUtil User’s Guide Table 4–3 (Cont.) Available Functions in the WebUtil_File_Transfer Package doesn't mention anything regarding the insert process ..
Regarding...
both have the sam contract_noit should be unique.
Hope this helps...

Webutil_file_transfer.client_to_db leaves file locked

I'm uploading a file to a BLOB column in the database using webutil_file_transfer.client_to_db. The problem is that the file is left locked in the filesystem.
(OS=Win2000pro, RDBMS=9.0.2.1.0.)
Is this a known bug, and/or is there a solution?
Closing the browser releases the file.
Regards,
Ernst.

We've had problems with webutil file reading/writting. Try putting two synchronize commands, one after the other before you upload.

WEBUTIL client_to_db file transfer

I cannot delete a file from the local client drive after using the webutil_file_transfer.clinet_to_db function, whilst the form is still running
-- CODE USED in Forms 9ir2
DECLARE
     result BOOLEAN;
     wordexe VARCHAR2(1000);
BEGIN
delete_check;
IF :ltr.datedl IS NOT NULL THEN
     lp_err_alert('Deleted letters may not be edited or opened.');
     RAISE FORM_TRIGGER_FAILURE;
END IF;
     COMMIT_FORM;
     result := webutil_file_transfer.db_to_client('c:\temp\'||:ltr.letter_id||'.doc', 'REF_LETTER', 'OLE_BLOB', 'letter_id = '''||:ltr.letter_id||'''');
     write_header_file;
     wordexe := 'C:\Program Files\Microsoft Office\Office\';
     client_host(wordexe||'winword.exe c:\temp\'||:ltr.letter_id||'.doc', 0);
     result := webutil_file_transfer.client_to_db('c:\temp\'||:ltr.letter_id||'.doc', 'REF_LETTER', 'OLE_BLOB', 'letter_id = '''||:ltr.letter_id||'''');
     IF NOT result THEN

     END IF;
     COMMIT_FORM;
     result := webutil_file.delete_file('c:\temp\'||:ltr.letter_id||'.doc');

          lp_err_alert('Failed to delete document');
     END IF;
EXCEPTION
WHEN OTHERS THEN
     lp_err_alert('Failed');
END;
What I find is that the webutil.delete_file fails. If you try and delete the file using explorer you get a file sharing violation.
When the form is closed you can delete the file from explorer.
If I comment out the client_to_db line the delete file works ok.
Is the client_to_db leaving an object lock in the java functions?
Anything I can do about this?

Nigel,
I don't know the bug number, but I remember that this is a known issue with the pre-release of webutil that is fixed in production. Unfortunately I don't know whether there exist a work-around or not.

Webutil_file_transfer and webutil_db_local

Hello
I'm trying to use WEBUTIL_FILE_TRANSFER.CLIENT_TO_DB to upload a file into a blob column in the database.
While debugging, in the function WEBUTIL_FILE_TRANSFER.UploadInt the following line of code exists:
if not WebUtil_DB_Local.openblob(spec1, spec2, spec3,'W', m_maxTransferSize) then ...
When I step into this function, this is what I see:
PACKAGE BODY WEBUTIL_DB_LOCAL IS
FUNCTION OpenBlob(blobTable in VARCHAR2,
blobColumn in VARCHAR2,
blobWhere in VARCHAR2,
openMode in VARCHAR2,
chunkSize in PLS_INTEGER default null) return BOOLEAN is
BEGIN
raise form_trigger_FAILURE; -- BY AN 30/6/2009, IT WAS WITHOUT THE "_local"
return WebUtil_DB_local.OpenBlob(blobTable,
blobColumn,
blobWhere,
openMode,
chunkSize);
END OpenBlob;
Do I have something wrong with my installation or something?
Thanks in advance for any help.

That is exactly what Andreas is saying. Here is the code for the OpenBlob function in my WebUtil.pll.
FUNCTION OpenBlob(blobTable in VARCHAR2,
                     blobColumn in VARCHAR2,

Forms is not cooperating at all!!

ok so idk maybe I'm just not intelligent enough to understand Forms but I have read through various Documentation on Forms 11g and done research on it and I have typed stuff exactly how I read about to put it and nothing seems to be working like it is supposed to.
I am working on making a page that can upload and download a PDF from the client's computer to the Database and back by use of buttons. The upload page has a browse button that is supposed to bring up an open dialog box using webutil and then when the user selects a file the file path of that file will be placed into a text box so that 1. they can verify that it is correct and 2. to store the file path for later. Then the user clicks the upload button and the button is supposed to pull the file path from the text item and store the file located in that location into the database.
here is the code for each of the buttons.
browse button:
DECLARE
     File_Path VARCHAR2(255);
BEGIN
     FILE_PATH := WEBUTIL_FILE.FILE_OPEN_DIALOG
          C,
          null,
          '*.pdf'
     :block.file_upload_text := FILE_PATH;
     Synchronize;
     END;
upload button:
Declare
     Result_Upload BOOLEAN;
Begin
     Result_Upload := Webutil_File_Transfer.Client_To_DB
          :block.file_upload_text,
          'file_tbl',
          'file'
End;
and the text box is in the data blocks drop down under buttons it was put there automatically by Forms. But when I try to compile it I get an Error 49 bad bind variable 'block.file_upload_text'
the text item name is spelled correctly and everything I have found online says that is how to access the text in a text item I dont understand what is gong on that it isnt working and I am really getting annoyed at Forms because no matter how much I read about it and how much of the little of what is available that I look at I can not figure out what is wrong.
Another problem I am having is that before you even get to this upload page there is another page and that page has a button that is supposed to pull up the upload page and I have figured out enough to figure out that I need the upload page canvas to be a data block in order to call it and then you use a go_block or something like that to pull it up but what I can't figure out is how to make that canvas into a data block... everything that I am finding is saying that to create a data block you need to call a table and stuff and I dont know how I am supposed to put that canvas into a table in the database so that I can create a data block with that canvas in it. I even found something that is supposed to walk you through how to do it and I got to like step 4 of 6 and it said to do something to do with double clicking the database node button or something and I looked everywhere and didn't find anything that said anything about database node. I have been working on this for about a month and a half now and it feels like I have gotten nowhere on it I still haven't even gotten to the download part at all.
I got this same program working completely upload and download in Java in 2 weeks then found out we needed it to work with Forms so I found out I needed it to be a java bean not just java so I tried to figure that out, couldn't seem to figure out how a java bean worked with what I was trying to do and the only documentation I was able to find that might have been helpful for it was on a blog which are blocked from my work computer and I was informed that Forms had something built in that did exactly what I needed, well that hasn't helped much either so far... I could really use some detailed absolutely as dumbed down as possible help here because I really need to get this thing done.
I know I rambled a little and I am sorry, any help that can be provided will be greatly appreciated!!

Sorry for feeling uncomfortable with Forms. But your, I think there is a lot of room fpr (re-)reading forms documentation and other educational handouts.
I won't solve yout problems, but may be I can give you few hints, tht came into my mind, when browsing yout post:
DECLARE
File_Path VARCHAR2(255);
BEGIN
FILE_PATH := WEBUTIL_FILE.FILE_OPEN_DIALOG( C, null, '*.pdf')
+:block.file_upload_text := FILE_PATH;+
Synchronize;
END;
1. What is C? You should get a compilation error since iot is nor declared.
2. Do you need a directory ot a file. If the first take FILE_SELECTION_DIALOG into consideration. Or may ist easier for you to use CLIENT_GET_FILE_NAME. For this function don't miss to set FILE_SELECT-Parameter to FALSE.
3. Are you sure the block, where the item FILE_UPDLOAD_TEXT is in is named BLOCK. Forms automatic naming will generate something like BLOCKn (where n is a number). But may be you have renamed the Block (what is common use).
4. Declaration of file_path is not really necessary; you may assigne the result of the Function immediately to your forms item (via bind variable :<block_name>.<item_name>)
5. Synchronize is not neccessary at this point, just costs a round-trip ofr the AS.
(6. I'm an fan of PL/SQLs named parameter syntax; it make code easier to read and to maintaine. So your function call would read
WEBUTIL_FILE.FILE_OPEN_DIALOG( directory_name => c, file_name => NULL, ...
just a suggestion, fell free to uswr or not)
The following is hard to understand. Probably you have a complete different understandind of how to program. You have to accept it's oracle forms an not sonething. That means there are certain structures:
1. Data
1 Form consits of one or several blocks; some of them may be connect to the database, often to a table, but it need not be a table; these are called database blocks, others (no database connect) are often called control block (but might also hold data).
1 Block consists of one or several items; some of them hold data in form of text, numbers, date, image, lists, radios ...; others are means to control the application, e.g. buttons.
2. View
1 Form consists of one or several windows.
1 Window contains one or more canvases; at least one content canvas; there are also other types, but I think you don't need them.
On the the canvases you "paint" all the things you want to sho to your users, your items (you have to make an item visible and assigne a canvas in the canvas property), free text, graphic elements.
You don't program a "page"! Your application is running within an applet within a page.
3. Logic
You may assigne logic via triggers to the elements of the data stack (form, block, item), not the view stack.
You may put logic into procedures and functions for better readability and maintainance; these can be stored locally in the form or in own libraries for re-use in other forms.
What trigger to use in which situation? That beyond my post.
A special topic here: you can extend forms functionality with java beans. You have to extend forms functionalty with java beans, if you need to get our of the applet sand box. You need that because you want to read/write information of your local client. Basic Java beans you find in WEBUTIL. It offers, I am sure, all the functionality you need. And you have found them.
So to get your problem solved of showing the whole stuff after pressing a button there a several possibilities:
easiest: create 2nd content canvas and put your items there; at the switching button issue GO_BLOCK('<block_name>') OR GO_ITEM('<block_name>.<item_name>'), where block_name is that thing that makes the compilation trouble.
bit mor an effort: create an own window with a new content canvas; the rest as described above; get some knowledge about SET_WINDOW_PROPERTY, espacially in cinjunction with the property VISIBLE, you will need it, whenn switching back;
even more effort: create an new forms + .... and call this form on the swithing button.
This might be a reasonable way if you want to re-use this function (up-/down-loading) from several forms.
Last sentence, in java it took 2 weeks?in forms, Iwould say it's a task for 2-4 hours (forms and webutil correctly installed nd configured). But I won't tell your boss.

How to use Client_Host without the exe file path

Hi,
i'm using oracle forms 10g,
in my application the users can upload any type of files (doc,xls,pdf,avi ,.. etc) and any user can download and open any of these files.
i implement this using client_host and including the path of winword.exe or AcroRd32.exe ,...
in many cases i don't know where these exe files are installed in the client side or whether it is installed or not.
i tried this command : client_host('calc.exe') it works and show me the calc without including the path of this exe file.
what i want to do is to just call the target file(doc,pdf,avi,..) in the client_host without having to precede this with the exe and path like the calc.exe example.
if you go to start->run and write for example c:\ahmed.mpeg , windows automatically call the real player or any other video software installed and open the movie.
can we implement this in oracle forms? and how?

Hi, you attach a procedure to download a file in the local runs from Windows and to close it updates in the database and then delete the local directory

How do I make the webutil file transfer works correctly?

Hello,
I'm using Oracle 10g Database and form builder in developer suite 10g release 2. Running on Windows XP SP2.
I've created a database user, executed the create_webutil_db.sql , and created a table as below:
CREATE TABLE DOCS
(DOC_ID VARCHAR2(15) NOT NULL,
DOC_IMAGE BLOB,
TEXT_DESCRIPTION CLOB,
FILENAME VARCHAR2(80),
FILE_SIZE NUMBER NOT NULL,
CONSTRAINT PK_DOCS PRIMARY KEY (DOC_ID)
I've created two buttons in the from, one for upload and one for download
the upload code:
DECLARE
     fname VARCHAR2(1000);
     fext VARCHAR2(1000);
     result BOOLEAN;
BEGIN
     fname := Client_Get_File_Name(null,null,null,null,OPEN_FILE,TRUE);
     fext := fname;
     WHILE instr(fext,'.') <> 0 LOOP
          fext := substr(fext,instr(fext,'.')+1);
     END LOOP;
     IF LOWER(fext) <> 'doc' THEN
          message('Only Microsoft Word Document (*.doc) can be uploaded');
     ELSE
          result := Webutil_File_Transfer.Client_To_DB
          (trim(fname),'DOCS','DOC_IMAGE','DOC_ID = ' || '''' || :DOC_ID || '''');
          IF result THEN
               message ('Upload success');
               :FILENAME := fname;
               :FILE_SIZE := WebUtil_file.file_size(:FILENAME);
               WHILE instr(:FILENAME,'\') <> 0 LOOP
                    :FILENAME := substr(:FILENAME,instr(:FILENAME,'\')+1);
               END LOOP;
          ELSE
               message ('Upload failed');
          END IF;
     END IF;
END;
and the download code:
DECLARE
     result BOOLEAN ;
BEGIN
     IF :FILE_SIZE > 0 THEN
          result := Webutil_File_Transfer.DB_To_Client
     (trim(Client_Get_File_Name(null,:FILENAME,null,null,SAVE_FILE,TRUE)),'DOCS','DOC_IMAGE','DOC_ID = ' || '''' || :DOC_ID || '''');
          IF result THEN
               message ('Download success');
          ELSE
               message ('Download failed');
          END IF;
     ELSE
          message('No file to download');
     END IF;
END;
I can upload the file to the database, and download the file.
However, the file being downloaded is corrupted. I don't know why this will happen. I've tried to rebuild the form, re-attach the webutil library, rebuild the database users and tables, but all these doesn't work.
Please help, thank you.

Webutil upload is holding the file that it uploads

Hi am creating n application using a lot of webutil commands to upload files that were scanned onto the users machine. I am having the following problem - after a call the webutil upload I try to call the webutil delete file to delete the file that was jsut uploaded off of the users machine. the problem is that once the file gets uploaded it does not get released until I am all the way out of internet exploerer - not only out of the application but totally out of internet exploerer.
I am going to attach part of the code and notice that I need to be able to delete the file from the users machine after it is uploaded.(in the same session)
v_random_number := random_number(6);
INSERT INTO NEEDS_TO_BE_MOVED (RANDOM_NUMBER,APPLICATION_NAME,USER_MACHINE_NAME,DOC_NAME,
                    DOC_MOD_DATE_TIME,USER_ID,DOC_TYPE,DOC_PAGE_COUNT)VALUES
                    ( V_RANDOM_NUMBER,V_APPLICATION_NAME,V_COMPUTER_NAME,V_ACTUAL_DOC_NAME,
                    SYSDATE,USER,NULL,NULL);
UPLOAD_BLOB_TO_DB(V_DOC_NAME,'RANDOM_NUMBER = '||V_RANDOM_NUMBER);
COMMIT;
v_boolean_delete_file:=WEBUTIL_FILE.DELETE_FIL(v_doc_name);
--this is the code for the UPLOAD_BLOB_TO_DB proc
PROCEDURE UPLOAD_BLOB_TO_DB(P_FILE IN VARCHAR2,P_WHERE IN VARCHAR2) IS
l_success boolean;
BEGIN

then

else
SET_ALERT('File upload to Database failed');
end if;

WEBUTIL (attach and view files from database) --- Vista vs. XP differences

I have attached the following code. We are using Oracle Application Server 10.1.2.3 patch
My questions are provided following the code.
-- Open the local temporary file --
-- v_COMMAND := 'cmd /c start "" /WAIT "' || v_FULL_FILENAME || '" /w';
v_COMMAND := 'cmd /c start "" /WAIT "' || v_FULL_FILENAME || '"';
v_PROCESS_ID := WEBUTIL_HOST.blocking( v_COMMAND );
v_TEMP := WEBUTIL_HOST.GET_RETURN_CODE( v_PROCESS_ID );
If v_TEMP <> 0 Then
r_ERR_MSG := 'Host command error(' || To_Char( v_TEMP ) || ')';
v_FLAG := WEBUTIL_FILE.DELETE_FILE( v_FULL_FILENAME ) ;
RAISE PANIC;
End if ;
if p_FILE_ACCESS = 'W' then
-- Re-store the modified file in the database --
If Not Webutil_File_Transfer.Client_To_DB ( v_FULL_FILENAME, 'mis_mst.FT_SUP_FILES', 'FILE_DATA',
'FILE_NBR = ' || To_Char( p_FILE_NBR ) ) Then
r_ERR_MSG := 'Error on storing file';
Raise PANIC;
Else
Clear_Message;
-- show_message('File re-stored in the database') ;
End if;
else
Clear_Message;
-- show_message('NOTE: "' || v_FILENAME || '" was not updated in the database' );
end if;
-- Remove the temporary local file --
v_FLAG := WEBUTIL_FILE.DELETE_FILE( v_FULL_FILENAME ) ;
If v_FLAG = FALSE Then
Bell ;
-- show_message( 'Error removing "' || v_FULL_FILENAME || '" from the PC.' );
End if ;
For the most part, we are able to open files in both XP and Vista. We are having a couple of problems with certain file types; specifically, (JPG and ZIP).
We have a workaround, but I would like to know why the problem occurs.
When the user opens a JPG from our application using the Windows Vista client (JPG are associated with Windows Media Player by default), the system will not open the file. The system states that the file doesn't exist. What I think is happening is that Windows Media Player takes awhile to load and before WMP is fully loaded, the file is deleted (the /WAIT command must not fully wait for the command to complete, causing Forms to continue with its code to delete the file). When WMP tries to open the file, the file has already been deleted from the operating system. I have tried the "/WAIT <filename>" and the "/WAIT <filename> /w" parameters.
The workaround is to reassociate the file with MS Paint or Microsoft Office Viewer (instead of Windows Media Player).
Are any of you aware of issues (or differences) in the wait command between Windows XP and Windows Vista?

Thank you, Thank you, Thank you!!!!
I believe that will work (adding a sequence number to the end of the filename)!
We do not allow a user to update the file, only view. If a user wants to make a change, they need to remove the existing file (from the database), create a new file (outside of our application), and attach the file in our application (into the database). All updates occur outside of our application - we are not a document authoring system, just a document storage system.
Once again, many thanks on the solution!

     :files.made_at:=sysdate;
end if;
end;
commit;
could anybody help me in this.

No, the form is not fine else you would not have this FRM error message.
Check the syntax of the parameters given to the WebUtil_File_Transfer.Client_to_db() Webutil function. add a message() instruction just after to see if the function if well executed.

Some JPG images, stored in DB, do not display on screen/image item.

Hi friends,
I have a form to save and retrieve images (JPG, GIF, TIF) to and from DB, using WEBUTIL_FILE_TRANSFER.CLIENT_TO_DB and CLIENT_IMAGE.WRITE_IMAGE_FILE respectively.
It’s working fine, but with few JPG images, it stores in DB but do not display on screen/image item.
Secondly, if I try to retrieve and write this JPG to OS (using CLIENT_IMAGE.WRITE_IMAGE_FILE), it prompts error “FRM-47101: Cannot write image file”.
Environment:
Forms [32 Bit] Version 10.1.2.0.2
OS XP Pro 2002 SP3
Oracle DB 11g Enterprise Edition Rel. 11.1.0.7.0 - 64bit
Any help will be highly appreciated.

Hi,
I have done a workaround here, which worked for me.
My requirement is to direct save images in DB. So my system was just saving images without knowing if picture would display on form or not later.
I created a (non-DB) image item on form and added a code (CLIENT_IMAGE.READ_IMAGE_FILE) to place image in this image item, if it successfully display image then save image directly in DB using code (WEBUTIL_FILE_TRANSFER.CLIENT_TO_DB).
Note: - If CLIENT_IMAGE.READ_IMAGE_FILE fails it raises exception and it means image has invalid format/internal data header and system does not save image in DB.
Now I have a kind of a filter to stop saving pictures which do not display later on form. :)
