Have no records I want to display some custom text in Red color in Advaced
Hi All
When I instantiate a query, if I have no records I want to display some custom text in Red color in Advanced Table instead of the standard No results found.
i.e. something like, 'click on Add Records'
Any ideas pls..Did u tried as Ravans suggested.
Put the indicators outside of the case structures. Wire across the borders of the case structure. It creates "tunnels".
I am not getting
but it displays both result at a time. but i want
to display the instruction first, to the user, so that they act
according to the instruction and ,than i want to display the result.
Try this VI.

How can I display some OrdImages using a Applet in html or Jsp?
hi
I want to use a applet to display some images retrieved from intermedia OrdImage Object.
Now ,I know that a applet can display some image objects or some images with their own filepaths. But we can get ordimag objects from Oracle database.And we can image data or image properties by ordimage java mathod. It is in html/Jsp environment. So how can I transform from ordimage to applet?? I appreciate someone who can help me!
BillDo you mean applet or Servlet?
An Applet is java code that is downloaded over the web and runs in a web browser environment. Is this what you are doing?
I suspect you are really talking about servlet/JSP environments, and the ability to include images from the database in a web page.
In either case (applet or servlet), you want to be able to access images via a URL. For a Servlet/JSP/web page, this URL will be specified in a HTML <IMG> tag with a key as a parameter to the image you wish to view. Images are not in-line downloaded in a web page. They are access after the HTML is loaded, and are accessed with URLs, sometimes relative URLs rather than fully specified URLs.
To deliver images to the web from the database using the PL/SQL gateway and iAS, where the procedures are generated by a wizard, see:
http://otn.oracle.com/software/products/intermedia/htdocs/descriptions/imedia_code_wizard.html
You can create a simple servlet (JSPs can not deliver binary data) that delivers database images using java classes. See:
http://otn.oracle.com/software/products/intermedia/htdocs/descriptions/servlets_jsp.html
http://otn.oracle.com/sample_code/products/intermedia/htdocs/intermedia_servlet_jsp_samples/imedia_servlet_jsp_readme.htm
for a sample. -
Displaying specified colors on the pie chart rather than default colors
Any ideas on how I can display my own colors on the pie charts rather than displaying default colors?
Hi,
You can specify your own colours by changing the default CSS styles.
Go to the Chart Attributes for the pie chart, and in the CSS section select Yes in the "Use Custom CSS" option. You can now edit the CSS for the chart.
At the bottom of the "Custom CSS, inline" setting, you need to add in two lines for each possible segment of the chart. Something like:
rect.data1{stroke:#FFFFFF;stroke-width:0.5;fill:green;}
path.data1{stroke:#FFFFFF;stroke-width:0.5;fill:green;}
rect.data2{stroke:#FFFFFF;stroke-width:0.5;fill:yellow;}
path.data2{stroke:#FFFFFF;stroke-width:0.5;fill:yellow;}
rect.data3{stroke:#FFFFFF;stroke-width:0.5;fill:red;}
path.data3{stroke:#FFFFFF;stroke-width:0.5;fill:red;}
This will set the colours of the first three segments to green, yellow and red respectively. Add in more rect.datan and path.datan entries until you have accounted for the maximum number of segments that your chart may contain.

How to change the area of cells used as pie chart legend?
In Numbers '13 I cannot drag the legend area separately (as I could do in Number '09). The same on iPad.
Did I miss something?re: ChartLegend
The line "chtChart.SeriesCollection.NewSeries" does nothing.
After legend entries have been deleted, the only way to restore them is to remove and recreate the legend that contained them by setting the HasLegend property for the chart to False and then back to True...
chtChart.HasLegend = False
chtChart.HasLegend = True
(the font in the new legend may need adusting)
It has been a very long time since I have created charts with VBA.
My Excel help file says to change the values used by a Chart Series you have to specify a range or provide an array of values (not both)
So this seems to work...
Dim X as Variant
X = chtChart.SeriesCollection(3).Values
chtChart.SeriesCollection(1).Values = X

rs.close();
psmnt.close();
connection.close();

ThanksI have done exactly that in one of my applications.
I have extracted the image from the database as a byte array, and displayed it using a servlet.
Here is the method in the servlet which does the displaying:
(since I'm writing one byte at a time, it's probably not terribly efficient but it works)
private void sendImage(byte[] bytes, HttpServletRequest request, HttpServletResponse response) throws IOException {
ServletOutputStream sout = response.getOutputStream();
for(int n = 0; n < bytes.length; n++) {
sout.write(bytes[n]);
sout.flush();
sout.close();
}Then in my JSP, I use this:
<img src="/path-to-servlet/image.jpg"/>
The name of the image to display is in the URL as well as the path to the servlet. The servlet will therefore need to extract the image name from the url and call the database. -
How to use ShowValue within a UIX/JSP page to display an active link?
I am storing URL's in the DB and want to display them as active links on a UIX/JSP page. I thought that I had this working some time ago, but now it no longer works.
Using <bc4juix:RenderValue datasource="ds1" dataitem="myTextField" /> will display "http://www.otn.oracle.com" as an inactive link using UIX/XML which is expected.
Using <jbo:ShowValue datasource="ds1" dataitem="myTextField" /> will display an active link using if using BC4J/JSP, which is expected.
However, I have not been able to do this using a UIX/JSP page.
Is it possible to use ShowValue within a UIX/JSP page to display an active link?
Thanks,

I've done the following and it does not work for me;
