It's seems the default column type is it_Edit

How to change the "name of column" property of an text item in runtime?
How to change the "name of column" property of an text item in runtime?
I look the properties of items in help and found nothing about this!
It's possible?Hi,
an other solution is change the block property QUERY_DATA_SOURCE_TYPE from "Table" to "Sub-query" , than change at run time the property QUERY_DATA_SOURCE_NAME.
First create block and add items
The QUERY_DATA_SOURCE_NAME will be for ex. "Select 'A' as col1, 'B' AS col2, 'C' as col3 from dual"
Set into items the column name property to col1 , col2 ...
At run time change the query to "Select 'Z' as col1, 'X' as col2 , 'Y' as col3 from dual"
in this way you can change the source of column value.
Caution because if you change value type from varchar2 to date you must cast date into varchar2.
May be that this way is valid only for view data not for insert-update, i don't remember.
bye

How to change font size, maximum column size in the result screen ?
hi All
That's great when using SQL Dev.
But I also have a trouble that how to change font size, maximum column size in the result screen ?
My users think that font in result screen is shown very small, and whenever the data in each colum is long then it's not shown full data in column, they must double click for extend the size. Have the option to default the max size for showing full data in each column ? I try but still not to do that .
Appreciate for anyone to help us.
Thanks all.
SigmasvnYou can't change the font for the results screen yet, however you will be able to select an auto-fit option for selected columns, so if some columns have slitghtly wider text you'll be able to set the column widths to handle these wider columns.
Also, there s the option of switching the layout of a record in the grid.

How to change nat type 3 to nat type 2 for Plastation 4?
how to change nat type 3 to nat type 2 for adaptation 4? i am havng a complicated time with this im'm just trying to play online and been at it fotr 3 days i have tried about everuyhing n portforwarding.com i have a Cisco Linksys E1000
Hi ceasar14. I actually found some steps (from a source) that worked for me. I'm not sure if it will work for you. Here are the steps:
1. Get the MAC address of your PS3. To find your MAC address simply go to
Settings > System Settings > System Information
2. Assign a static IP address on your PS3.
3. Access your router's user interface to open a few ports.
4. Under Applications and Gaming > Port Range Forwarding, open the following ports:
TCP: 80, 443, 5223
UDP: 3478, 3479, 3658
5. Once this is done, powercycle your PS3 and the router.
6. Run a connection test and check if it is now on NAT2.
Good luck. -

How to change data type of content type column.
Hi all,
I am having one content type. I have 10 columns in it. There are two rich text columns in my content type. I have attached this content type to pages library. I want to change the data type of this rich text column to "Full
HTML content with formatting and constraints for publishing".
Please assist me with this issue.
amolHi,
From your description, my understanding is that you want to change the data type for rich text column in content type.
The field type of Full HTML content with formatting and constraints for publishing is "Invalid", you could refer to this article:https://msdn.microsoft.com/en-us/library/microsoft.sharepoint.spfieldtype.aspx.
You also could test it by create a Full HTML content with formatting and constraints for publishing column and get the its type with C# code below:
//change the URL to your SharePoint site
using (SPSite site = new SPSite("http://sp/sites/sharepoint2013"))
using (SPWeb web = site.OpenWeb())
SPFieldType type = web.Fields["Column name"].Type;
I have tested it with the PowerShell, it cannot hange the rich text column to “Full HTML content with formatting and constraints for publishing” column. If you want to edit the rich text column, you could not change the type of the column as the screenshot
below:
As a workaround, you could follow these steps to accomplish your requirement:
Create a “Full HTML content with formatting and constraints for publishing” type column in the content type.
Enter your site columns by clicking gear icon -> Site Settings -> Site columns under Web Designer Galleries under section.
Find and delete the rich text column you want to change.
Find the column you have created in step 1, and change the column’s name to the name of the text column you have deleted in step 3.
But you will lose the data of the rich text column in pages library with this method.

Vincent Han

catch (Exception e) {
log("Error during search for packages airtime", e);
return null;
public String searchButton_action() {
search_action();
this.tableRowGroup1.setFirst(0);
return "";
}I put the search_action() call in the prerender() to have data in my table when the page is open. For a large resultset the best aproach is to let the user select some search criteria and then call the search_action() using a button (searchButton_action() ).
I've added a hyperlink column to my table, it is used to display the current record details in a new page.
I have defined in my SessionBean a getRowkey/setRowkey methods.
When the user click on a "View" hiperlink the following code is executed:
public String viewpackageAT_action() {
RowKey row = tableRowGroup1.getRowKey();
this.getSessionBean1().setPackageAirtimeRowKey(row);
return "packageairtime_details";
}I will step over the "Page Navigation".
In the Detail Page I have the following code:
public void init() {
this.s23_package_airtimeDataProvider.setCursorRow(this.getSessionBean1().getPackageAirtimeRowKey());
}Now I have the detail page opened and also the DataProvider opened at the saved RowKey value.
Finally, in the SessionBean:
* Holds value of property packageAirtimeRowKey.
private RowKey packageAirtimeRowKey;
* Getter for property packageAirtimeRowKey.
* @return Value of property packageAirtimeRowKey.
public RowKey getPackageAirtimeRowKey() {
return this.packageAirtimeRowKey;
* Setter for property packageAirtimeRowKey.
* @param packageAirtimeRowKey New value of property packageAirtimeRowKey.
public void setPackageAirtimeRowKey(RowKey packageAirtimeRowKey) {
this.packageAirtimeRowKey = packageAirtimeRowKey;
}Note: You should enable page navigation in the result(s) table.
That's about it :)
Hope this helps,

How to change page type after the fact
In the application builder, I click on an application and choose Details in View.
I get the list of pages I have in my app.
The page type column has:
Interactive Report
Navigation Form
Dynamic HTML
DML Form
Chart
Report
How do I change this column after a page has long been created?
Specifically, I want to the change "Dynamic HTML" to something else.
Why?
Because on this particular page, tabs do not work (error: page not found).
Buttons created among a regions items do not work (same error, page not found).
I need to use tab and buttons to go from this page to other pages.
And I am suspecting the page type may have something to do with my problem.
Thanks in advance for any pointers.Thanks for your consideration!
For my current app, a clinical management system,
I'd like to have, say, 1000 items.
(For other applications I am thinking about, but have no time,
nor expertise for now, I'd need millions of items,
each corresponding to a pixel of a graphic.)
Who cares if the current computers are too slow?
How about make it a parameter that can be changed
per app or per apex installation, and default to 100?
Some forms can be broken up logically, as people have helpfully suggested,
and I did follow that advise on some pages.
But other forms cannot be. People have put a lot of thought on designing
those forms, they are government or legal standards (or at least something more important
than computer performance), and people have been trained
with those original forms.
Consider the hoops I have to jump through to get more than 100 items
on a page I am currently working on:
Generate the items (INPUT type="text" and INPUT type="checkbox") using PLSQL
lots of htp.p('<INPUT ...>').
a JavaScript function to collect all the values on the page
and make up an XML string. submits this string to an application
process, and application process parses the XML string and does insert or update.
Another JavaScript to populate the items based on the current values of a row,
using an application process to retrieve the columns of a row.
There are about 150 items on this particular page.
All these are ok, because I was aware of the restriction of 100.
And because I wanted to generate my own HTML to mimic the original
form anyway.
Then things started to go weird.
I need buttons to go back to another page. and I use tabs.
Buttons to go back from this page,
when a button is created with "Create a button in a region position",
it works fine.
When a button is created with "Create a button displayed among this region's items",
it does not work, and I get HTTP 404, https://.../apex/wwv_flow.accept, page cannot be found.
But I need a button to work like the one created with "Create a button in a region position",
but displayed like the one created with "Create a button displayed among this region's items".
This is still not too bad. I saw the difference between the two kinds of buttons.
I copied the HTML code for the button "Create a button in a region position",
and used a display only item to create a Back button where I wanted:
'<table class="t15Button" cellspacing="0" cellpadding="0" border="0"><tr><td class="t15L"><img src="/i/themes/theme_15/button-l.gif"/></td>'||
'<td class="t15C">Back</td>'||
'<td class="t15R"><img src="/i/themes/theme_15/button-r.gif"/></td></tr></table>'
Here P145_BACK holds the page number to which I want this page to go back to.
Then I noticed that the tabs did not work any more. same error, page not found.
That's is when I got a little frustrated and posted for help on the forum.
Then I begin to undo my steps, and
by lucky accident, I noticed that, if none of the checkboxes is checked,
the tabs work fine. If at least one is checked, I get this error, page not found.
My current solution is to add a function of my own in the doSubmit(B) function in file apex_3_1.js,
which unchecks all checkboxes (o.checked=false).
And now, from this page of about 150 items,
the tabs are ok, and I have a button that is similar to one
created with "Create a button displayed among this region's items", except I created myself
using HTML.
I think this trick of using a custom function in doSubmit(), that unchecks or even hides
INPUT type="text" items (o_div.style.visibility = "hidden"; o_div.style.display = "none";)
should work in general. this function is only invoked when the user clicks the tab,
or buttons among a region's items.
Somebody said regarding restrictions on drugs or sex.....
you will not make people stop, you just make it harder or more expensive.
Same here and many other things, a restriction is just making things harder.
People will try to get around it.
Now that I have a solution, and I am aware of the problem, I'll calm down and
go back to my own thing for now.
Maybe you are looking for
