XControl dynamic default value

Hello,
Do you know how to make a XControl give a numeric value like Tick Count (ms) ? I think that is not that obvious. Tick Count is typically a node which value changes at every moment based on external parameters.
See the attached example. When a VI containing the XControl is "Run when opened" then the returned value is always zero, instead of Tick Count. This is related to the default value of the XControl data extracted on the Block Diagram before the Facade VI is called. Note that I need to use a XControl for other reasons, not a SubVI for instance or else.
Does anywone know how overcome this zero systematic value (still using a XControl) ?
Best regards

Hello,
You can
remark that when the VI was load one time and that you don't close LabVIEW, you
can reduce the delay because the Xcontrol is already in memory. But you need to
keep a delay due to the redrawing of the Xcontrol. When you use a lot of
Xcontrol or a big one, it's better to preload the xcontrol before using it to
reduce the launch time.
Best regards.
OK enlighten me, how to do such a thing for an executable. Why can't the owning VI wait on the XControls?

Prompts with dynamic default values

I have a request from my client to modify several reports so that two date prompts will have default values populated with the first and last day of the previous month. All of the reports are currently using custom sql so I have to be able get the dynamic default value in the extended @prompt syntax. However, I am not able to use any of the sql functions since the functions merely appear as plain text as the default value itself.
I have found a few work arounds to achieve the functionality of the dynamic prompts, but I cannot get the actual default value displayed to the user to be dynamic. Is it possible to achieve this by using only the custom sql?

PS
Is the second thread i create with this question cause i didnt receive any answer before and i am really interested in any solution or knowing that i cant perform it.

no one have ever used a date parameter (for example, month) that need a default value, and set this default value as the month we are today?
maybe i didnt explain my problem properly before...
thanks for any help, i really need this because all the porlets in the portal i am creating are discoverer's reports that presented by month, year or day.

Dynamic default value on SREQ area

Hi everybody,
I would like to set default value for one field on search screen,
however not fixed value (what I can do in field group of the area),
but dependent on some condition.
Where should I put my code?
regards,
Przemek

Hi,
Default values are the ones that appear when the screen loads. So what kind of condition can you check when the screen loads. Incase of any events driven out of navigation then we can set some values.
Could you make the requirement a little more clear.

Dynamic default value to dateTime filter

Hi,
In my report I want to show data with *"datetime>4 AM today to datetime<current datetime"*. How to set the default value of a datetime filter to 4AM of the current day?
Thanks
Edited by: SOADreams on Sep 22, 2011 12:43 PM

Hi
You could try the following:
Create a calculated field to determine if the Hour is 4AM or greater -- use the timefunctions and set the value to 1 for fields that satisfy the criteria using If then Else
Set the filter to Current Day and then also where the calculated field is 1
I think this will provide you the right set of records.

Setting dynamic default values in a list/menu

To save problems with inserting dates into a Mysql database, I have split the input fields on the file insert form into three drop down lists containing the day, month and year.
In order to make it easy for users, I wish to take the current date, split it into day (dd) month (mm) and year (yyyy), and use one of these values as the default option for each of the three fields.
In html you would use :
<option value="2012" selected>2012</option> for the default, but this is a fixed default.
I want it to change depending on the actual year., so that if today is 21-02-2012, (thats how we use dates in the UK) the three fields default to 21 (dd) 02 (mm) 2012 (yyyy).
I can re-format them into MySql date format mmddyyyy no problem later to insert them into the database
Any ideas?
Or is there a better way to do this?

<option value="2012" <?php if (date('Y') == '2012') echo 'selected'; ?>>2012</option>
The above solution works well for that item.
I now have another one which may help others.
I populate a drop down list with the values 1 to 12, with the default being set to 6 and insert a record.
This represents the number of months that the record will be displayed until it is deleted.
When I pull the record back from the database to update it, I need to show the current value of the field, which is stored in $row_eventset['event_expiry'] ready for it to be updated.
Code as follows:
<select name="event_expiry" size="1" tabindex="5" title="select from the list">
<?php for ($i = 1; $i <= 12; $i++) { // loop through the months
          echo "<option value= '$i' " ;
      if ($i == $row_eventset['event_expiry']) {                               //check if this is the same as the record being edited
       echo 'selected="selected" ' ;                                                 // if so select it
            echo ">$i</option <br>";                                                  // the <br> is essential in a browser, though it works without it in live view.
?>
</select>
I hope that it saves someone some time.
When I first tried this, it worked fine in live view. However in a browser, all the months appeared on the same line. I had to insert the <br> command to make it work properly.

Problem using default value of report parameter 1 to validate parameter 2 passed in to report

I am having a problem with an SSRS report using the default value of report parameter 1 to validate parameter 2 passed in to report (via C#) instead of using the value of parameter 1 that is also passed into the report. Here are the
simplified details:
Using SSDT, SQL Server 2008 R2
SSRS report has 2 parameters:
P1 -- text, hidden, default value 'R1', ... front-end C# code can pass 'R2' or 'R1'
P2 -- text, allows multiple values, list of available values provided by stored procedure (sproc_list) that takes P1 value as a parameter. Hence, sproc_list either provides a list for P1 = 'R1' or P1 = 'R2'.
List for P1 = 'R1' is 'A', 'B', 'C'
List for P1 = 'R2' is 'A', 'B', 'D'
Values for P1 and P2 can be passed in via C# to the report.
The C# front-end displays 2 report choices to the user, R1 and R2, where both choices call the same RDL; but choice R1 passes in 'R1' for P1, and the choice R2 passes in 'R2' for P1.
Upon a users 1st time use of the report no parameters are passed in. Then when the user exits the report, the parameter value for P2 that was chosen is saved off to a file for R1 or R2, and used the next time the user selects the report.
Everything always works fine for report R1 since the default value for P1 is 'R1'.
When R2 is chosen and the user selects 'D' as the value for P2, runs the report, then exits, the P2 value of 'D' for R2 is saved to a file. When the user returns the next day to run report R2, 'R2' is passed for P1, and 'D' is passed for P2.
This is when the problem occurs. The value of 'D' for P2 is validated against a list generated for P2 based on the default value of 'R1' for parameter P1. Hence, SSRS considers 'D' an invalid value for P2 and blanks out the P2 parameter.
The user can then use the drop down list for P2 and choose 'D', but this defeats the purpose of saving the parameter values to be used the next time.
Why is the stored procedure that provides a list of available values for parameter P2 using the default value of 'R1' for parameter P1 instead of using the value of 'R2' passed into the report for parameter P1?

Hi Tom,
Sorry for my delay.
If I understand correctly, you have two parameter in your report. It is a couple of cascading parameter. If we have choose ‘R1’ of P1, the P2 values is A, B, C. ‘R2’ of P1, corresponding P2 values is A, B, D. What your requirement is to save the end use
select option of these two parameters.
In SSRS, if we have configure the parameter with default value. When we run the report, the parameter will fill with the default value to filter data. If we want to save the last status we are render the report, we need to update the default value of P1.
If we are query the default value from database, if possible, we can
update the database try to resolve the issue. Alternatively, we can set the dynamic default value for the parameter.
Hope this helps.

Set default value based on current day value and setItems in Design studio

Hello
I have 2 filters on my dashboard - year and month. The default display of the dashboard should populate current year data. Is it possible to create formula to populate dynamic default value based on the current date using setSelectedValue() ?
Also, for the calendar month, the items are set as below
DD_MONTH.setItems(DS_1.getMemberList("0CALMONTH",
MemberPresentation.INTERNAL_KEY, MemberDisplay.TEXT, 12, "ALL");
This displays month values as 01/2014, 02/2014 ... How can I change these value to display as January if mm = 01 and February if mm = 02 etc..
Thanks
Sirisha

Hi Victor,
I have tried using below statment to populate current year as the default selection value for the dropdown. Used it on Startup, but for some reason it loads all the data when the dashboard is opened the first time. Any ideas?
DS_1.setFilter("0CALYEAR",[Convert.subString(APPLICATION.getInfo().dateNowInternalFormat, 4,6)]);
Thanks

Is there any way to achieve this in OBIEE 11g?

Hi,
If you are using the same presentation column (same TableName.ColumnName) in your analysis and in the prompt, then the values would be passed when you click on the link. If thats not the case, you can have a look at the below post:

How to include a default value in Dynamic cascading prompt from 2nd Level.

Hi,
I use Command Object in 'Datbase Expert' to create 'Custom Tables' and use these tables to fetch LoVs. I use Dynamic Cascading Prompts in the reports. I have a peculiar requirement using DCP.
There are Four Levels as in the Example:
Continent
   Country
   State
   City
In the Custom Table, requirement is to create an additinal row with '' that represents 'All Values selected' for that level starting from second. and The default selection should be '' . I defined that '*' means 'All Vales Selected in the report' This si not a problem. But the problem how to show a default value in a Dynamic Cascading Prompt i.e. how we can make sure in an default value can be selected in DCP from Second Level?
how can the examples 1,2,3 can be achieved detaisled below beacsuse we need to show a default value in Casacading Propmt
Eg of Schedules with DCP:
Schedule 1
Continent: Europe
   Country: *
   State: *
    City: *
Schedule2:
   Continent: Europe
   Country: England
    State: *
     City: *
Schedule 3:
    Continent: Europe
   Country: England
    State: Greater London
     City: *
Schedule 4:
Continent: Europe
   Country: England
    State: Greater London
     City: City of london

You won't be able to have a true "default" value in the various cascading levels, since there aren't default values in a dynamic cascading parameter. That being said, I've created a sample report in Crystal Reports 2008 that has a Command-driven DCP with '*' values for the 2nd and 3rd levels of my 3-tier DCP and have accounted for them in the record selection criteria. You can find the sample here at https://www.box.net/shared/mav5qp337j

How to make a default value by using dynamic actions

Hi,
       I want to default a field nationality in infotype 0002 as a great britan, using dynamic actions but unable to go ahead. Any help regarding this really appreciate.
Regards
Niranjan

Hi,
I need some guidance around creating dynamic action with default value, Please guide me through.
I am aware I can set default values for new infotype, but I need to set default value for same infotype, let me explain the scenario.
Currently employee is on one pension scheme which is called NE1 and now we are moving this employee to CRESP Pension Scheme.
When employee is in NE1, his IT0071 has got a opt in field with a flag on, when the same employee is moved from NE1 pension scheme to CRESP Pension scheme, his new IT0071 record should have the same opt in field with a flag on, I want it to set this flag automatically using dynamic action. I dont want to update this field manually, while moving from NE1 to CRESP.
Currently the below dynamic action is coded when employees are being moved form NE1 to CRESP, but now they will have a opt in flag which should appear automatically, What needs to be done to make this happen?
Please let me know if I set default value for the Opt in field for the same infotype.
. When employees are being moved from NE1 to CRESP pension scheme we currently use a dynamic action as show below:
0071                      04      10      I        INS,0069
0071                      04      20      W       P0069-BEGDA=P0071-BEGDA
0071                      04      30      W       P0069-ENDDA=P0071-ENDDA
0071                      06      1        F        DYNACT_PAE031(ZHRPROG016)
Also if it is not possible via dynamic action could you please explain how to create it using user exit, I am not an ABAPer.
Your help is very much appreciated.
Kind Regards,
SK

How to dynamically get default value from a table column

Hi all,
Here's my problem: Our front end application sends insert and update queries to a pl/sql package. I've got a procedure that gets a PL/SQL table with all the column names an values, a table-name and a primary key name and value. That procedure creates an insert or update statement. So far, so good.
Now the problem: our front end doesn't know what the default value for a column is. So when a number field doesn't get a value in the front-end, it's inserted with a value '0' though is should ben NULL. My sollution for this is to know the default value of a column: when there's a default of '0', then the value that will be inserted is '0'. When there's no default value and the column can ben NULL, it'll be inserted as NULL. if the column has a not null constraint, a '0' will be inserted.
Ofcourse I can get the default value from the system-views all_tab_columns or user_tab_columns, but our application is installed at some 100 clients, and has various database installations. Most of the times, the tables are in the same schema as our procedure that performs the insert or update, but sometimes some of the tables are in another schema (in the same database) and also sometimes some tables are stored in another database. In all these situations, a synonym for that table exists in the schema.
Is there a api function or procedure that I can call to get the default value of a column? I looked at dbms_sql and dbms_metadata, but those packages don't give me that perticular information. if not, I'll stuck with the 'does table exists in schema' yes->use table, no query user_synonyms to look for the owner of the table (and database link) and query all_tab_columns to get the default value. Only this seems a bit overkill to me.
I hope I'm clear enough? And please don't reply with "don't do inserts this way"! I know, this is not the most optimal sollution, but it does gives us a couple of advantages in our application...

there is no way that I can think of, apart from what you have already discovered (i.e. views), where you can determine if a column has a defuault value defined against it.
The other option is triggers, but I guess doing that across 600 tables would not be an option, and besides I stay clear of triggers.
A different approach therefore, if you cannot pre-determine the data, is to consider a post problem handler, hence I suggested the use of an exception handler.
The exception handler works regardless of whether the statement is dynamic or not.
