Webutil_Host and Client_Host

Hi,
I am wondering what is the difference between Webutil_host and Client_host?
I am trying to call sqlplus.exe located in the server and run a text file in the client side. I am wondering if I use webutil_host or client_host?
Thanks in advance!

Hi,
client_host is a wrapper that is rovided for API parity. Client_Host calls Webutil_Host. If you need non blocking calls, or an ID retruned instead of an error code then use webutil_host.

Webutil_host or client_host delete all files...

I am trying to delete files within a directory on a client's machine through my forms 9i web application and it's not working???
I tried
client_host('cmd c/ DEL c:\gdocdocs\');
client_host('cmd c/ DEL /F c:\gdocdocs');
webutil_host.nonblocking('cmd c/ c:\gdocdocs\');
webutil_host.nonblocking('cmd c/ DEL c:\gdocdocs\');
Thanks,
Terry Sicard

IMHO For Windows 2000, the command should be
cmd /c DEL /Q c:\gdocdocs\*.*
/Q - Quiet mode, do not ask if ok to delete on global wildcard
You could also try:
echo Y | del c:\gdocdocs\*.*

PROBLEMS USING WEBUTIL_FILE_TRANSFER AND CLIENT_HOST COMMAND TO VIEW BLOB

I am using webutil_file_transfer.DB_To_Client_with_progress to retrieve a blob
from the database (that was saved in a word format) into a .doc file on the
client.
1st problem: The document that is being saved is not readable. It has all
kind of special characters in it.
Then using the client_host command, I open the document into ms word.
2nd problem: The document opens fine (again not readable in garbage
characters) but when I close the document, notepad pops up blank with nothing
in it.
Below is a sample of the code.:
PROCEDURE DOWNLOAD_DB IS
l_success boolean;
username varchar2(30);
document_name varchar2(20);
wordexe varchar2(20);
BEGIN
     username := webutil_clientinfo.get_user_name;
     document_name := 'wo'||:wod.fk_work_order_number||'.doc';
     :locals.file_name := 'Documents and Settings\'||username||'\my documents\'||document_name;
l_success := webutil_file_transfer.DB_To_Client_with_progress
(clientFile => 'C:\'||:locals.file_name
,tableName => 'DEFECTS'
,columnName => 'DESCRIPTION'
,whereClause => 'FK_WORK_ORDER_DATE_ID = '||:DEF.FK_WO_DATE_ID
,progressTitle => 'Defect document being opened'
,progressSubTitle=> 'Please wait'
if l_success
then
CLIENT_HOST('cmd /c start /wait winword.exe C:\'||'"'||:locals.file_name||'"');
else
message('File download from Database failed');
end if;
exception
     when others
     then
     message('File download failed: '||sqlerrm);
END;
Any ideas?

Hello,
I use this kind of code with 9i and 10g and it works fine with word, excel and any of windows files.
I think that, if the file is not correct, the cause may be the first save of the file in the database.
Which instruction did you use to save first the doc in the BLOB column ?

Forms 10g, SqlLoader and client_host

Hi,
I am starting Sql Loader from Forms 10g by using client_host(sqlldr.exe userid=..). The Sql Loader works fine, data is loaded to ORACLE tables but the application fails to go back to the Forms code and execute the rest. I have also tried to call a batch file by using client_host but the problem persists, the SqlLoader works fine but the rest of the forms code is not run.
Thanks for suggestions,
Deniz

As said that would be exactly for that purpose. When you call applications in blocking mode which prevents the forms applet from sending a heartbeat for a certain amount of time the forms runtime will assume the forms applet is dead and will exit. nonblocking_with_callback will return control immediately and call a user defined trigger after the application has ended. Just create a user defined trigger with the code you want to execute after SQL*Loader is finished. Pass the name of that trigger to non_blocking_with_callback, and your problem should vanish ;)
cheers

WEBUTIL_HOST.blocking and winword 2003

Hi all,
I got some problems using webutil_host and winword 2003.
As i open a document with winword in blocking mode, works well if word is not already open.
Eg if word is already open it dunot do the blocking stuff, and go back to forms immediatly.
here is the code :
LC$Cmd := 'cmd /c start "" /WAIT "winword.exe'||'" '|| Path_vima;
Ret := WEBUTIL_HOST.blocking( LC$Cmd ) ;
fms_message('back from call');
LN$But := WEBUTIL_HOST.Get_return_Code( Ret ) ;
If LN$But <> 0 Then
Set_Alert_Property( 'AL_ERREUR', TITLE, 'Host() command' ) ;
End if ;
So if winword is not open on client -> it works well
if winword already open -> it dunot block and display fms_message('back from call');
Plz Help :)
Thanks
PS : this work perfectly with Excel ....

Ok seems that dunot work even if not using forms.
as launch a cmd like cmd /c start /WAIT winword
it wait the close of winword to continue execution
but if i launch winword first and than try a
cmd /c start /WAIT winword
it open a second winword but dunot wait for word to be close.....
that's to bad .
I'll try look at MS forum

Hw to use OLE and HOST

Hi ,
According to my prj requirement.I have to devlop a form in Oracle 10g.A textbox and button is there .After entering a value in text box and on pressing the button.It should execute a perl script and after perlscript is executed it creates a textiles and stores it in its server.After that I want to diplay that text file in the form.In form 6i it was possible to do it through OLE.
So hw can we achieve there 2 jobs.
1.To iteract with perl script and execute it.
2.Finally display the text file in Form.
Thanks in advance.

to execute an .exe file or a script we use HOST in forms6i and CLIENT_HOST in forms 9i/10g.
If you are familiar with OLE2 in forms 6i then just replace it with CLIENT_OLE2 for forms10g.(but first attach wbeutil.pp to your forms10g)
chek this demo of forms9i webutil:

Hi,
Thanks for your reply .. But, how ? Do you have or know link which can show me how to use webutil and client_host ?

Calling an external program (*.exe file) on the client

Hi,
I use 9iDS and I'd like to call an external program (*.exe file) on the client, but this exe file is located on the server not on the client.
So it should be something like a mixture between host and client_host(webutil) command. Is it possible to use client_host where a virtual path is passed to?
Regards Sören

Are you saying you want to run on the exe on the client but its located on the server???
In that case you would have to do a webutil file transfer to move it to the client before executing. Or, if you are calling a DLL, webutil will download it automatically from the server to the client (see the C API example on the webutil page).

Manipulate client side files?

Hi,
I would like to manipulate client side files using APEX.
Is there any functionality available for APEX similar to the functions provided in Oracle Forms 10g WebUtil?
such as:
CLIENT_HOST and CLIENT_TEXT_IO
is there a way of using these functions in APEX?
more specifically: I want to use CLIENT_TEXT_IO to create a batch file on the client, and CLIENT_HOST to execute the batch file in the cmd line on the client(windows)...
could anyone suggest a way of doing this in APEX?
thanks in advance
Leon

No, Forms over the web uses a Java applet in the browser, thus allowing them to manipulate client-side files. APEX does NOT use an applet (this is a good thing, btw) and thus has no native capability to manipulate client-side files. However, you could write your own Java Applet or ActiveX control (go with Java if you can, it works in all browsers) and embed this in an APEX page.

Webutil copy very slow

I've the following problem : the webutil_file.copy_file is very, very slow : i takes 3/4 minuts for a 400k file.
The problem become even wrost if the file is larger (1mb) : it ever run into a timeout.
It is not a network problem : if i copy the same files by hands it takes milliseconds.
What the problem could be ?
Any workaround ?
Tks
Tullio

This is from metalink WebUtil: Technical FAQ. Doc Id 270940.1
WEBUTIL_FILE.COPY_FILE is slow when copying large files to a network drive.
The underlying implementation is not optimal. While the performance difference may not be a problem on small files, it may be better to use WEBUTIL_HOST and call the OS "copy" program where possible.

Using WEBUTIL for OLE2

I have installed WEBUTIL (Beta 1.3) and developed an easy application which tries many of the features:
- webutil_clientinfo

Try to call wfs.exe (MS fax and scan) with webutil_host !!

hi,
I would call from Forms the MS scan and fax application “wfs.exe”.
This is found under windows\system32.
call:
WEBUTIL_HOST.NONBLOCKING ('cmd /c C:\windows\system32\wfs.exe');
Unfortunately, nothing happens. No error message and no cmd-process remains open in the taskmanager.
with other applications it works. For example:
WEBUTIL_HOST.BLOCKING('cmd /c C:\Windows\System32\notepad.exe');
WEBUTIL_HOST.BLOCKING('cmd /c C:\Windows\System32\calc.exe');
I use Forms 10.1.2.3 on Windows 7.
Does anyone have any idea or can test that if it works?
thx Alfred

you can use
WEBUTIL.client_HOST ('cmd /c C:\windows\system32\wfs.exe',hide_screen);
instead of
WEBUTIL_HOST.NONBLOCKING ('cmd /c C:\windows\system32\wfs.exe');
which will run the wfs.exe file located in the windows\system32 directory. if client machine is on the windows O/S
you can view the process list by tasklist command on the command prompt.
you can use cmd /k option for remaining in that session for the errorlevel checking.
