First of all, i would split the subjects column.
If you for sure only need up to 3 subjects, you could make three columns subject1, subject2, subject3.
If you may have an indefinite number of subjects for each teacher, you might create a detail-table with the subjects for each teacher.
I also would create a list of values for the subjects, either based on static values or based on another table with the subjects allowed.
Now that the subject-names are fixed you could create a subject-image for each subject, named as the subject itself. Then you "construct" the image for each subject as
<img src="#APP_IMAGES##SUBJECT_NAME#.png"/>

How to find the average of table row values it should display in next row in libwindow/CVI

Hi,
How to find the average of table row values it should display in next row in libwindow/CVI
Please let me know the solution.

There isn't a built-in function to perform calculations on thable cells. What you can do is to retrieve thable cells values and calculate the average by yourself.
To retrieve a bunch of cells in a single instruction you can use GetTableCellRangeVals: prerequisite for this function to work correctly is that cells are all included in a Rect structure (shortly, a rectangle) and are all of the same data type. See the help for the function for some explanations and the link to an example of its usage. In Cell range parameter you can pass VAL_TABLE_ROW_RANGE (row) macro to retrieve an entire row. See here for details.
Once you have retrieved cell values in an array, you can pass it to Mean function to calculate the average.
Proud to use LW/CVI from 3.1 on.

How to display 7 values of single field in row wise.

hi,
how to display 7 values of single field in row wise.

do it like this :
1 Place ur UI element in tranparent container with Layout as Row Data and Layout Data as Row Head Data
2 Ur first UI , which contains the first value as Row Head Data ,
3 Others as Row Data
u can do it with Matrix Data as well
if u want to give space , u can use HORIZONTAL GUTTER and set its width to medium / large / Xlarge
also there is a UI element "INVISIBLE ELEMENT" ,
1 u can use this UI element to provide space between ur other UI elements in the view
2 u can insert a text element as well , and in the Text property of the element press ALT + 0160.
u can give the space bw UIs as desired.

How to find max based on 2 columns.

Hi I have a table where I have two numeric fields (date and time) )(thouse field are not date time format but numeric)
Column A represents date and column B represent time.
How would I find max value of column A and with results for A find Max for B.

You can try one of the following...
sql> select * from temp;
         A          B
    101010     202020
    101011     202021

1 select a,b from (
2     select a,
3            b,
4            rank () over (order by a desc, b desc) rnk
5       from temp
6* ) where rnk = 1
sql> /
         A          B
    101012     202021
1 select a,b from (
2    select a,b from temp
3       order by a desc, b desc
4* ) where rownum = 1
sql> /
         A          B
    101012     202021Please try to provide create table statements and insert data scripts instead of "select * from table".
It helps creating your case easier.

Edited by: Alvaro Tejada Galindo on Feb 6, 2008 12:01 PM

Thanks all for the reply.
I am trying to solve a problem where report parameter value that is set at Management Console is wiped out after calling replaceConnection.
databaseController.replaceConnection(oldConnectionInfo, newConnectionInfo,
null,DBOptions._doNotVerifyDB);
We have to support changing database connection from a java utility
class. But once replaceConnection is called all existing static parameter values are lost. To fix this issue we thought of getting parameters and values before calling replaceConnection and setting it after replaceConnection.
Version is CS2008 SP3 - version 12.3.0.601
If there is any other option of fixing the original wipe out issue?
ParameterValues.getValues() didn't return value. I will try ParameterValues.getCurrentCalues() but the document says ParameterValues.getValues() is equivalent to the IParameterField.getCurrentValues() method unless it is empty, in which case it is equivalent to the IParameterField.getDefaultValues() method.
So getCurrentValues() may not work.

Hello, SAP Gateway Server Host and Gateway Service are used to set up rfc connectivity, that is the host name and the system number where your sld and ldap is responding, if you have no sld and no ldap , just simply uncheck that options while installing.

The logic is same but the way u open ands execute the code is a bit diff.
