How can I pause a slide until the user clicks a button?
I wish to pause a slide until the user clicks a button (which I've created out of a Smartshape). The thing is that I haven't added a click box object over the smartshape but have only set the smartshape properties to "Use as Button". If I were to add a clickbox object, I would get a "Pause project until user clicks" in the options section of the properties. However in using a smartshape as a button, I cannot find this option. I am using Captivate 6. Seems strange as I would have expected to see the same checkbox option even if I were to use a smartshape as a button but I dont. Can't someone help me and let me know if I'm missing something.
Of course I could use a clickbox over my smartshape to achieve what I want, but I want to avoid thsi for two reason:
I want to avoid adding another object when I dont need it.
My smartshape is a right arrow (indicating "Begin"), and I dont want a squarish click box sitting on top of a triangle because that just shows the hand pointer even if the cursor isn't exactly over the arrow button because it enter the clickbox area.
Thanks,
SeanSelect the Smart Shape button , go to Properties > Timing accordion > Pause After and set the number of seconds from the beginning of the slide for it to pause.

Invalidate session when user clicks back button

}The problem with even attempting to do this is that with today's browser capabilities, users can optionally choose to jump to a particular page in the browser history and this may not necessarily be the most recent page. In this case, you would also want to invalidate the user's session after already having been there (whatever page that may be). Then you have situations when the user may wish to jump back in history to external pages they were visiting before they reached your own site's pages. Then what happens when they start clicking forward, forward, etc... from there? This is why I prefer writing Swing Clients as alternatives to browser applications. There are soo many possible ways break web applications made for standard web browsers both maliciously and simply by accident or irregular user patterns. Regardless, this servlet would work based on the assumption that all the user(s) would "ever" do aside from moving logically forward is clicking on the browser's "back" button.
cheers!

For this you have to use portal navigation classes, Same scenario occurred in previous forums, search thoroughly before you post the question.

What happens once an user click shutdown button
when an user clicks shutdown button, what OS does
1. will it stop all the process running in the background right away and spend time in closing those?
2. apps (exe) which were running won't be having any control and it is fully operating system which does everything
to kill all the running processes right?
3. What is the exact flow that OS follows to kill apps when shutdown button is pressed.?Hello Sarath_dnv,
About the Windows Shutdown details, please take a look at the following article.
http://blogs.msdn.com/b/b8/archive/2011/09/08/delivering-fast-boot-times-in-windows-8.aspx
1. The user initiates a shutdown by selecting “shut down” from the Start menu, or by pressing the power button; or an application initiates shutdown by calling an API such as ExitWindowsEx() or InitiateShutdown().
2. Windows broadcasts messages to running applications, giving them a chance to save data and settings. Applications can also request a little extra time to finish what they’re doing.
3. Windows closes the user sessions for each logged on user.
4. Windows sends messages to services notifying them that a shutdown has begun, and subsequently shuts them down. It shuts down ordered services that have a dependency serially, and the rest in parallel. If a service doesn’t respond, it is shut down forcefully.
5. Windows broadcasts messages to devices, signaling them to shut down.
6. Windows closes the system session (also known as “session 0”).
7. Windows flushes any pending data to the system drive to ensure it is saved completely.
8. Windows sends a signal via the ACPI interface to the system to power down the PC.

Weird thing about when user click Update button
Hi,
I got a very weird thing when i want to add some my code in button "1" on click event. I use below code to capture the on click event when user click "Update" button, so i can do some tasks(assign some fix value to a specific field). I found i can capture the event only once. Once the document is updated and i open second recordl then my code is never exexuted then. No error, no exception. Is anyone know what happen?
Thanks,
LanHi All,
Yes, you are right. After i use try block, i can see the error. I thought I should be expected an red exception alert in the B1 info bar.
Thank you !

Treat enter key the same as clicking button without using javascript
I have a page with a search on it. I would like to let the user press the enter key, and have it be the same as if they clicked the search button.
I figure I could do this with javascript, but I'm wondering if there's an easier way.
3.2.
Edited by: tharpa on May 5, 2011 7:33 AMTharpa,
You can make your search field a text field with submit. This will submit the page and make the request the name of the item when the user presses enter while this field has focus.
I cannot currently look at a 3.2 instance and be more descriptive about how you can do this, but if i remember correctly it was a sub option of the text field.
Thanks,

Handling Enter key event in JTable
Hi...
This is particularly for the user "VIRAVAN"...
I have followed your method ,and got results too.. but the
processKeyBinding(.. method is called 4 times,same problem addressed by you before, but I didn't understood it...
Please help me...
Here is my code...
protected boolean processKeyBinding(KeyStroke ks, KeyEvent e,int condition, boolean pressed)
System.out.println("Wait");
if (ks == KeyStroke.getKeyStroke(KeyEvent.VK_ENTER,0))
int selRow = getSelectedRow();
int rowCount = getRowCount();
int selCol = getSelectedColumn();
String val =(String)getValueAt(selRow,selCol);
boolean b= getCellEditor(selRow,selCol).stopCellEditing();
System.out.println(b);
System.out.println(rowCount-1 + " "+ selRow + " " + getSelectedColumn());
if((!val.equals("")) && selRow==rowCount-1)
System.out.println(rowCount-1 + " "+ getSelectedRow()+ " " + getSelectedColumn());
blank1 = new String[columns];
for(int p=0;p<columns;p++)
blank1[p]="";
Diary.this.datarows.addElement(blank1);
// dataModel.fireTableStructureChanged();
//dataModel.fireTableDataChanged();
Diary.this.dataModel.fireTableChanged(null);
else if(ks ==KeyStroke.getKeyStroke(KeyEvent.VK_1,0))
System.out.println("One One One One ");
return super.processKeyBinding(ks,e,condition,pressed);It's been a while since I looked at the code, but essentially there are three key event types:
1) key pressed,
2) key typed,
3) key released.
So I would expect the processKeyBind to see all three of them. However, ks==KeyStroke.getKeyStroke(KeyEvent.VK_ENTER,0) is true only when a key typed event is detected (the other types can be ignored by passing it up the food chain where they will eventually be consumed). Now...., if I understand you correctly, you want to terminate edit on the present of Enter key, right? Here is how I'd suggest you do:
protected boolean processKeyBinding(KeyStroke ks, KeyEvent e, int condition, boolean pressed) {
if (isEditing()) {
Component editorComponent=getEditorComponent();
editorComponent.stopCellEditing();
return true;
return super.processKeyBinding(ks,e,condition,pressed);
}Ok.... now, it appears that you want to do something else also... i.e., add a new row to the table if the editing row is the last row and the editing column is the last column of the last row. You can't do that in the same thread (i.e., you must wait until the update in the current thread is completed). So, what you must do is use the SwingUtilities.InvokeLater, like this:
protected boolean processKeyBinding(KeyStroke ks, KeyEvent e, int condition, boolean pressed) {
if (isEditing()) {
Component editorComponent=getEditorComponent();
editorComponent.stopCellEditing();
if (getEditingRow()+1==getRowCount() && getEditingColumn()+1==getColumnCount()) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
// put the code for adding new row here
return true;
return super.processKeyBinding(ks,e,condition,pressed);
}OK?
;o)

Editable ALV - handling Enter key when pressing enter on keyboard
Hi folks.
Now I have searched - and found a lot of threads - in this forum about my little problem.
I'm using the <b>Function Module: REUSE_ALV_GRID_DISPLAY - NOT THE OO-version</b>!!!!!
I have a editable list as result of finding some data. My problem is.
When I change the value in one of the cells, and press the Enter key (not a click with the mouse on the Green button with the checkmark!) nothing happens!
I have
i_callback_pf_status_set = 'SET_PF_STATUS'
i_callback_user_command = 'USER_COMMAND'
And when I put a breakpoint in the USER_COMMAND form nothing happens - <b>ONLY IF I CLIKS WITH MY MOUSE ON THE Green button with the checkmark</b>!!
Hope U have some idea!
Best regards

How to handle 'ENTER' Key on ALV Editable Grid on sub screen (Tabstrips)
Hello Experts ,
I have 2 questions with ALV Editable grid;
please help me if you have answers.
I created ALV grid on one of sub screens on a Tab Strip,
As soon as user types one of the columns of the ALV grid and press u2018ENTERu2019 key, it has to return corresponding details for that line.
I tried to implement this logic in ALV grid event u2018handle_data_changedu2019, but ALV internal table is not getting populated with new entry entered in the grid. but u2018double_clicku2019 event working my purpose, but user might need enter key.
and I thought I would do implement that logic in PAI event of the sub screen, u2018ENTERu2019 key not getting trigger on PAI event of the screen until cursor is on grid.
Another question 2: How do I control and not to be deleted a line on the grid (based on validation), where do I validate and by pass the delete function for a particular line, or suggest me to gray out only one line on the grid .
I would like to have delete function to work as it is ,except for some validations..
Can I implement using PAI event of the sub screen or any by ALV event.
Please suggest me..
Edited by: Ravindranath Arusam on May 13, 2010 2:42 PMIn DATA_CHANGED event, you will get the modified row into the attribute MP_MOD_ROWS of the impoerting object ER_DATA_CHANGED. Since this MP_MOD_ROWS is the Object reference to Data, you need to have the field symbol to get the value.
FIELD-SYMBOLS: <lft_mod_output> TYPE t_t_output.
ASSIGN er_data_changed->mp_mod_rows->* TO <lft_mod_output>.
You can get the Value of the Cell by using the method GET_CELL_VALUE of the same ER_DATA_CHANGED object and use the method MODIFY_CELL To update the value back to ALV.
To Restrict the row deletion:
When the row is deleted it is being added to Attribute mt_deleted_rows of the object ER_DATA_CHANGED. You can put the data back to the table in the DATA_CHANGE_FINISHED event. Visit this post http://help-abap.blogspot.com/2008/10/alv-disable-delete-key-on-keyboard-in.html for more information.
