Guys, How do I write a trigger to call Calulator /Notepad???

How do I write a trigger to call Calulator /Notepad???
how do i make a button to call the notepad editor in windows and calculator?
of course i know about making the button, i want the code behind the trigger....

Kid, while you are providing more information on exactly what you are trying to do please make if clear if you are asking about a database table trigger or a Forms trigger?
As a general rule I would think an action such as calling a Windows specific feature should be done external to the database via the application.

EMP_C_NAME VARCHAR2(20 BYTE)
ON COMMIT PRESERVE ROWS;
CREATE OR REPLACE TRIGGER TRI_GLOBAL_TEMP
BEFORE DELETE OR UPDATE OR INSERT
ON GLOBAL_TEMP
REFERENCING NEW AS NEW OLD AS OLD

trigger was create successfully, but the wouldn't insert into to EMPNAME Table..
Please guide whether am correct or not? if not kindly give a correct syntax with example
Thanks in Advance,
Arun M M

BEGIN
INSERT INTO EMPNAME VALUES (:OLD.EMP_C_NAME);
END;
you are referencing old value in insert stmt.
BEGIN
INSERT INTO EMPNAME VALUES (:new.EMP_C_NAME);
END;then run ur application it works fine...

How to Write a trigger to hold session data

Hi Everyone,
There are 4 Weblogic Servers which are connected to the database concurrently. In the database I have Application Users table "USERS". When a user is logged to the application let us say userA(from "USERS" table) is logged into the application, whenever that same userA logged into the application from other Weblogic server(other system) it should not allow to login into the application. Is it possible to write a trigger for this. If possible, Can any body suggest how to write a trigger to hold that UserA data into one temporary table as long as that userA is active and removes the data from temporary table when userA logged off (OR) as well as that Weblogic server is goes down.
Thanks in advance.

Hi Justin,
First Thank you very much to all of you.
1. Yes Application Users are authenticated only once,
that to at the time of login to the Application.
2. We are not running any script that informing the
message like "connections
from the downed server should be reset". Do you
you think is it suggestable.
It's not mandatory to use triggers only.Can we
achieve this by maintaining any temporary table.
I have one idea is that, Lets create a table name
e "App_Users_Session_Data(User_Id,Is_Active)"
If "User A" logins into the application then User_Id
= 1A and Is_Active = 'T' will be entered
automatically into the table
"App_Users_Session_Data". When same "UserA" logins
from other Weblogic Server then Application first
check this table and informing that "UserA" already
logins and is active.
Whenever "UserA" loggsoff then this entry will be
automatically deleted.
My doubt is "UserA" logins successfully into the
application and corresponding user entry is there in
"App_Users_Session_Data". If Weblogic Server goes
down from where this UserA logins, This entry will
not be deleted. If this entry is still there then the
same UserA should not login into the application from
the same Weblogic server(which is up again). My doubt
is how to remove this entry automatically when
Weblogic server goes down. Can we achieve this by any
other way. If possible can u give some guidelines
thats enough for me.
Thank you everyone
SankarHi,
First off all and as I undeerstood you can change your application.
1- A table say weblogic_servers have to be created:
Several scenarios are possibles. If you want you can have a row per weblogic server in this table with what you want as identifier. Any way this table can have a column (sid for example) which identifies the weblogic database session. This can be managed by logon and logoff triggers for the related database user. The logoff trigger for example deletes all lines in App_users_Sessions_Data (see below) related to the same session as the weblogic server and puts the session sid in weblogic_servers to NULL.
2- Change the table App_Users_Session_Data:
You have to add a column (sid for example) linking the app user to the database session of the weblogic server. When a user connects, you can check if the databse session is always there and decide accordingly.
A good idea in my opinion is to centralize your logic by putting it in an INSERT trigger on App_Users_Session_Data.

How to create conditional update trigger in sql server

How to create conditional update trigger in sql server

You cant create a conditional update trigger. Once you create an update trigger it will get called for every update action. However you could write logic inside it to make it do your activity based on your condition using IF condition statement
Say for example if you've table with 6 columns and you want some logic to be implemented on update trigger only if col3 and col5 are participating in update operation you can write trigger like this
CREATE TRIGGER Trg_TableName_Upd
ON TableName
FOR UPDATE
AS
BEGIN
IF UPDATE(Col3) OR UPDATE (Col5)
BEGIN
....your actual logic here
END
END
UPDATE() function will check if column was involved in update operation and returns a boolean result

How do you write a file involving the changes in application engine?

Hi ,
My Requirement is Quite different here.
I cannot use CI.i have to implement in app engine.
Below explained:
I have data coming from abc table and populating into xyz table.
So if any field in abc gets changed which is extracted and populated in the xyz table.I have to show the old field value of xyz and the new field values of abc which I am going to insert into the xyz.
My log file should have both the values.
how do I write both the values and update it:
say I have value from abc.id=12 and xyz.id=12
when we update abc.id=13 and xyz.id=14

How do you write UNDO for a text item?? examples? or a REDO??

How do you write UNDO for a text item?? examples? or a REDO??
I created a pop-up menu with CUT, COPY, PASTE, UNDO, CLEAR for my text items.
Using MAGIC menu type works great but there is no MAGIC for UNDO or REDO.....
How do you write UNDO for a text item?? examples? or a REDO??
I have Oracle Forms 6i...
Lets say I highlight all the text in the text item, and start typing over it... then I realize OH NO it is the wrong text field...
Now I want to UNDO the typing and get back to the previous text.
I'd use the initial value that was populate right? How do I access that if that is correct?
Thanks, Bill

You can use;
<ITEM> := Get_Item_Property(<ITEM>,DATABASE_VALUE);
Or you will have to write a pre-text-item trigger;
PRE-TEXT-ITEM:
:CTRL.CURRENT_VAL := :<BLOCK>.<ITEM>
MENU (PL/SQL):
:<BLOCK>.<ITEM> := :CTRL.CURRENT_VAL;
You may also want to set the item property back to ITEM_IS_VALID so that item validation does not fire again.

I own the movies and I want them to stay in my iTunes library basically forever.
But in both cases the file name no longer shows in the movie list, so I don't know how to re-download it from the Cloud.
iTunes prefs > Store > Show iTunes in the Cloud purchases.
This will show all your iTunes purchases in your library with a cloud icon down arrow. Click the icon to redownload or click on Play to stream without downloading.
Also see this , -> Download past purchases
and techncially, you don't "own" the movie, You simply have a license to use it.
Yet the first thing iTunes does when you hit the delete key is tell you that it will remove the movie forever from all devices and the library.
Actually, no it does not tell you that.
FYI: You should keep copies of all yoru iTnue spurahses as the labels/movie studios/copyright owners can pull their product at anytime and it won't be available to redownload.

HI GUYS, HOW CAN I REGISTER THE ADOBE CREATIVE CLOUD ON MY MACBOOK AFTER REGISTERING IT ON MY IMAC THX TO ALL

HI GUYS, HOW CAN I REGISTER THE ADOBE CREATIVE CLOUD ON MY MACBOOK AFTER REGISTERING IT ON MY IMAC THX TO ALL

I am not clear on what you mean by "register" but if you mean you want to install it on another machine then you just need to install it the same way you did for the first machine.

How can I write a program that compiles without warnings?

I tried the following with the 1.5 beta-compiler (build 28; I think):
class Y {
     public static final class Pair<X,Y> {
       private X fst;
       private Y snd;
       public Pair(X fst, Y snd) {this.fst=fst; this.snd=snd;}
       public X getFirst() { return fst; }
       public Y getSecond() { return snd; }
       public String toString() { return "("+fst+","+snd+")"; }
public static void main(String... args) {
     Pair[] pairArr = new Pair[10];              // supposed to be an array of Pair<Integer,Integer>
     for (int i=0; i<pairArr.length; i++)
         pairArr[i] = new Pair<Integer,Integer>(i,i);
     for (int i=0; i<pairArr.length; i++) {
         Pair<Integer,Integer> p = pairArr; // unchecked warning
     System.out.println(p);
     Integer first = p.getFirst();
     Integer second = p.getSecond();
// ... more stuff ...
It turns out that I get an unchecked warning when I extract an element from the array of pairs. Okay, that's fine. How can I avoid the warning? I had expected that an explicit cast would help.
Pair<Integer,Integer> p = (Pair<Integer,Integer> )pairArr;
With a cast I'm telling the compiler: "I _know_ what I'm doing; please trust me." But the compiler still issues a warning.
How can I write a warning-free program in this case? The only thing I can think of, is not using the parameterized type Pair in its parameterized form. But it's not the idea of Java Generics that I refrain from using parameterized types. What am I missing?

It turns out that I get an unchecked warning when I

Pair<Integer,Integer> p = (Pair<Integer,Integer>
)pairArr;
With a cast I'm telling the compiler: "I _know_ what
I'm doing; please trust me." But the compiler still
issues a warning. Yes, but at least you were able to change the warning from "unchecked assignment" to "unchecked cast" which is a little shorter ;-)
Seriously , since arrays of generic types are disallowed, there is probably no way to get rid of these warnings - which makes a strong point for eliminating "unchecked" warnings altogether (see the other thread "selectively suppressing compiler warnings")

How can I write a code that triggers when clicking on Save button

I want to hide certain fields inside my tracking list, if the login user is not part of the “Managers” group.
To do so I want to add the following Page-load code inside a web part :-
using (SPSite site = new SPSite(SPContext.Current.Site.Url))
using (SPWeb web = site.OpenWeb())
{SPGroup group = site.Groups["Managers"];
bool isUser = site.IsCurrentUserMemberOfGroup(group.ID);
if (isUser)
{textbox.Visible=false;}}
And the following custom code that triggers when saving the form :-
using (SPSite site = new SPSite(SPContext.Current.Site.Url))
using (SPWeb web = site.OpenWeb())
SPList list = web.Lists["ListName"];web.AllowUnsafeUpdates = true;
SPListItem item = list.Items[SPContext.Current.ListItem.UniqueId];
txtTitle.Text = item["Title"] as string;item.Update();web.AllowUnsafeUpdates = false;
But I am not sure where exactly I should add the custom code for the save button ? I tried writing it inside the Oninit method , but I got many errors as shown below:-
So can anyone advice how i should write the web part to include the Page load & the custom save button code?
second question in general is my above approach considered valid , i mean to hide/show list columns using web parts ?

Hi,
According to your post, my understanding is that you want to hide/show list columns based on specify the permission for Users, SharePoint Groups or Active Directory Groups.
Here is a solution from CodePlex for your reference:

How can I Write a sine wave in an Access-file?

I measure a sine wave in LabView 6i. How can I write the datas automatically to an Acces-file, at the same time?
In my program, I managed it with Execute SQL.vi, I change a number in a SQL statement(String) -> after this I push start and then it writes the statement in the Access-file.
The problem is, it writes only one data per measurement in the file. How can I write all datas in the Access-file and measure the wave at the same time?
Thanks for help!

getwave.vi ‏49 KB

On the waveform palette, you will find a "to components" vi that you can break out the array of the waveform. You can then, using a for loop write all of the values from the waveform.
Better yet, there are examples in the database toolkit manual on pages 3-13 to 3-15 that deal with reading arrays (and even has a waveform example).
Good luck!

How to over write VBBE data when Delivery is created if at the time of SO creation stock blocking is there

Hi,
I want to know how to over write VBBE data after delivery creation if stock blocking is there at the time of SO creation.
That means I want my confirmed delivery quantity to over write the SO quantity in VBBE table after delivery creation. Please help me with your valuable suggestions...
Thanks
Tanmoy

Hi Tanmoy,
This should happen automatically. The VBBE entry should reflect the quantity of the delivery requirement. Is it possible for you to post screenshots illustrating exactly what is happening on your system?
