Programmatically determine control default value

Hullo,
I'm trying to figure out a reasonably supportable method for detecting whether a sub VI's input is wired.
I'm using the approach of setting a nonsensical default value for the control, then comparing the control's current value to a constant of this value. If they're not equal, then I pass the control's value into my shift register. If they are equal, I retain whatever value was previously in the shift register. In this instance, I've created an action engine that allows me to update status and progress bars.
This works because my progress counter is a U8 which I will only ever write 0-100 to, so I can set my default to something outside this range (here, 255) for my comparison. Something similar should be relatively simple to understand and reuse in the future.
However, there's a dependency on someone setting the default value for the control and then updating the comparison constant to match. My question: is there a method for checking the default value of a control programmatically in order to remove the coupling? I realise that any method would invariably be slower in terms of execution, but this is merely out of curiosity.

Thanks tst.
I was thinking more of future expandability and use rather than maintenance.
The default value method works for any input for which you can define a default value, so it can be used for anything your imagination stretches to. This may be a trivial example, but I can foresee someone in the future copying the architecture and ignoring the documentation.- but that's my problem, not anyone else's!
As I mentioned, it was mostly out of curiosity rather than an actual wish to use it. I'll have a look at the default value via scripting for posterity, but if you were going down the scripting route you could also use the Terminal Checker method. This doesn't work in the RTE either, though.
Thanks again!

"File Path Control" default Value

Hi - How do we set or change the default value for "File Path Control" (Control --> String & Path ---> File Path Control)?
I typed the default path into the control field on the front pannel and save the VI file. The value gone when I reopen the file.

jimmy.chretien wrote:
[...] difference between Not a path and Empty path... Why?
Not a Path is a specific value for the path (<Not a Path>).
Developers should use this to prevent situations in applications, where a user has to select a path before performing an action (e.g. saving a file). If the user skips the path selection, the application still has "Not a Path" and can prevent errors and tell the user to select the path (error handling!).

Control/Default values in Service Notifications and Service Orders

Hi all,
When in transaction IW52 and IW32 I know you can maintain a set of default values for when you are either creating a Service Notificaiton and/or a Service Order.
My scenario is as follows:-
User 1 has a set of default values and it contains Work Centre A. User 1 then creates a Service Notification.
User 2 has a set of default values and it contains Work Centre B. User 2 then reviews the Service Notification created by User 1 and wishes to create a Service Order.
When User 2 creates the Service Order, the default value for the Work Centre is using User 1's Work Centre (Work centre A) and not their own Work Centre of Work Centre B?
What is stopping User 2 picking up their own Work Centre of Work Centre B when they want to create a Service Order from a Service Notification?

Gary,
The order takes its data from the notification (which got it from USER1's defaults).
What you need to do is change the notification work centre to that of USER2's preferred default value.
There is no standard setting for this. However, all is not lost. It may be possible by misuing one of the order user-exits

Initializing Control Inputs to default value.

This may be a stupid question, but I am new to labview. When the VI is started I want it to read the data from the PLC(via the OPC Server)initially to set up the controls default value. Then if the user wants to change it, they can type a new vlaue.
Currently every time you start labview in clobbers the data in the PLC with its default value. I thought of using a write on change tag, but then it doesnt show what the current set point is.
Thanks
Thad

If you wanted to get the PLC values before makeing any changes to them, I would recommend using a Tag Read and update your front panel control with the use of a local variable. This would be an initialization routine.
Another possible answer to your question is that you will want to use the Options >> Make Current Values Default selection on your Front Panel. This way anytime your VI is reloaded it will start with these default values.
Thanks,
Bryce

User defined function to set a default value of a column

Hi All
Can we use user defined function to set a default value of a column ??
for example:
create or replace function test1 return number is
begin
return 10;
end;
create table testt
(id as test1,
name varchar2(20));
error:
ORA-02000: missing ( keywordThanks

ORA-04044: procedure, function, package, or type is not allowed hereUsing PL/SQL code like that raises 2 basic problems. If that PL/SQL code for the calculating the column default breaks, what happens to the SQL insert statements against that table. These will need to fail as the table definition depends on the PL/SQL code. This is problematic as this dependency simply increases the complexity of the SQL object.
The 2nd issue is performance. PL/SQL code needs to be executed by the PL/SQL engine. This means a context switch from the SQL engine to the PL/SQL engine in order to determine the default value for that column. Context switching is a performance overhead.
So even if it was possible to use a PL/SQL function as parameter for the SQL default clause, I would not be that keen to use it.

Feature to default values on infotype screens

Hi All,
Could I use a Feature (txn PE03) to determine the default values on an infotype screen?
For example, I want the value in field FUNKT on Infotype 34 to default to say 'KLMN' if the Employee Group is '1' and the Emp. sub group is 'Z5'.
I would like to use the screen modification config (table T588M) to assign the Feature and get the values without coding.
I know I can achieve this by using a subroutine on dynamic actions or a BADI for infotype processing etc. but I am lazy and don't want to code if I can avoid it.
Many thanks in advance
Sanjay

Thanks Sarika.
I can create a Feature in PE03 but how do I use that in the config (table T588M)? Because if I am not able to use it in the config, I will be forced to code (using any Fn. Mods of the likes of HRFEATUREBACK*).
The Feature ABKRS doesn't seem to be specified in table T588M as such there is bound to be coding behind it in the IT0001 processing programs.
Cheers,
Sanjay

How to display JHeadstart flex item default values

Dear All,
I have defined a number of FlexRegions and FlexItems and I'd like to display the default values (specified by a SQL query in the Flex Item Def Editor) next to the input text field using the JSF EL expression #{row.defaultValue}.
This works fine as long as the user has not provided a new value for the flex item. Once (s)he has done this, the default value gets cleared. I've been able to programmatically obtain the default value by invoking the method executeDynamicQuery("somename", row.getDefaultValueQuery()) on the FlexItemDefsOuterJoinedWithFlexItemsRowImpl instance, but
I'd like to be able to always display the original default value in the .jspx page.
Any suggestions would be greatly appreciated.
I'm using JDeveloper 10.1.3.3. and JHeadstart 10.1.3.2.52.
Regards,
Ibrahim

Hi Steven,
Thanks for your reply. You're absolutely right of course. We wanted to provide functionality to submit 'request for change' requests, whereby we would display the current value of a given attribute (e.g. salary) next to the new value provided by the user.
We wanted to 'misuse' the default value query aspect of flex items for this purpose. The flex item default value query would be used to retrieve the current value each time the request for change record is displayed.
We managed to achieve this via a trick, so please consider this post as solved.
Once again many thanks for a marvelous product.
Regards,
Ibrahim

Hi,
According to your description, you want to set default value for TaxonomyWebTaggingControl.
I have a test in my environment. It could be achieved by setting the Text Property of TaxonomyWebTaggingControl.
Here is the code snippet:
TaxonomySession session = new TaxonomySession(SPContext.Current.Site);
SPSite site = SPContext.Current.Web.Site;
TermStore termStore = session.TermStores["Managed Metadata Service"];
Group group = termStore.Groups["GroupA"];
TermSet termSet = group.TermSets["A"];
Term term = termSet.Terms["A1"];
TaxonomyWebTaggingControl1.SspId.Add(termStore.Id);
TaxonomyWebTaggingControl1.SSPList = termStore.Id.ToString();
TaxonomyWebTaggingControl1.TermSetId.Add(termSet.Id);
TaxonomyWebTaggingControl1.TermSetList = termSet.Id.ToString();
TaxonomyWebTaggingControl1.AllowFillIn = true;
TaxonomyWebTaggingControl1.IsAddTerms = true;
TaxonomyWebTaggingControl1.IsMulti = false;
TaxonomyWebTaggingControl1.Text = string.Format("{0}|{1}", term.Name, term.Id.ToString());

I am not sure how it works in Web Dynpro for ABAP, but in Web Dynpro for Java to set default drop down value you will have to set the value for particular attribute (which is linked to the dropdown element) in the context
like
wdContext.currentContext<nodeName>Element.set<FieldName>(<defalut value>)
This generally done in Initialization method of the controller.

How to find a default value to AutoComplete Control

Hi,
I am using AutoComplete control where i populate it with data from an oData service
var control= new sap.ui.commons.AutoComplete({
displaySecondaryValues: true,
items: {
path: "/",
template: new sap.ui.core.ListItem({text:"{NAME}", key:"{HOSPITAL_ID}", additionalText:"{STATE}"})
This is my implementation in fragment and in on after rendering I want to bind a default value to it.How can I achieve this?
for e.g.:
In drop down box I can achieve this with the below code
_myController.dropDownBox.bindProperty("selectedKey","HOSPITAL_ID");
I tried with similar approaches for AutoComplete control but I cannot bind value to it..Anyone can suggest a possible solutions please?
Best Regards,
Amala Suganya

Hi,
if you want to display default value in AutoComplete then you can do it as below,
                var oAuto1 = new sap.ui.commons.AutoComplete("TextField-1", {
                                tooltip: "This is an Auto Complete TextField",
                                change: onChange,
                               value: aData[5].name,
                                maxPopupItems: 2,
                                ariaDescribedBy: "MyDesc",
                                ariaLabelledBy: "MyLbl"
value property is used to display default value. alternatively you can use setValue method.
also refer this example AutoComplete - sap.ui.commons

XML FORM - How to save read-only controls with a default value

Hello everybody,
I have a 3 xml forms, each one to create one type of news. I need to use 3 because each of this forms has their own controls. But the control which indicates the type of news (asociated with a KM Predefined Property) must be common in the 3 forms, in order to use it on searches.
The question is, how can I include in this forms a control:
- Visible for the user
- With a default value defined in the control properties (each form has a different value, corresponding with the type of news)
- Read-only mode
- The value showed in the control must be saved in the associated KM Predefined Property when the user clicks the Save button.
Anyone knows how to do this?
What control can I use?
I was thinking of trying with text boxes, but I don't find the way to make them unwritable (Read only mode).
It is posible using labels?
Thanks.
Kind regards

Hello Jose,
I know you responded with a question... I see it in the email, but I don't see it here! Very odd... but in response:
The first thing I do when I open the Edit.xsl file is do a 'find' for the name of the text field that I want to be read-only (in my test case, it's 'location'). Repeat the find until you see something like:
[code][/code]
Below there is where I put the new code. Mine looks like this:
[code]- <xsl:choose>
- <xsl:when test="location='' and ($editmode='create')">
- <xsl:choose>
- <xsl:when test="./xf:ValidationError/@tagname='location'">
- <input name="location" size="30" type="text" class="urEdfiTxtEnbl" id="field_1157467268006">
- <xsl:attribute name="tabindex">
- <xsl:choose>
<xsl:when test="$accessibilitymode='true'">21</xsl:when>
<xsl:otherwise>3792</xsl:otherwise>
</xsl:choose>
</xsl:attribute>
- <xsl:attribute name="value">
<xsl:value-of select="''" />
</xsl:attribute>
- <xsl:attribute name="readonly">true</xsl:attribute>
</input>
</xsl:when>
- <xsl:otherwise>
- <input name="location" size="30" type="text" tabindex="3792" class="urEdfTxtEnbl" id="field_1157467268006">
- <xsl:attribute name="value">
<xsl:value-of select="''" />
</xsl:attribute>
- <xsl:attribute name="readonly">true</xsl:attribute>
</input>
</xsl:otherwise>
</xsl:choose>[/code]
I put the <xsl:attribute name="readonly"> in both places (when test, and when not test). I'm not entirely sure if that's necessary, but that worked for me.
Hope this helps,
Fallon

Setting control to default value when it is a strict type def

If my subVI has a control that happens to be a strict type defined cluster and I have saved the values in the control as the default values, how can I change them back to the default values of the type def (which are empty). Because it is a strict type definition, i cannot click on the elements inside the cluster and modify them (e.g. click on an array inside the cluster and do an empty array operation.)
In the attached screenshot, the control "BLE Meters To Test" is just an array of clusters and I was able to empty the array. The control "Capture Data" is a strict type def. I would like to clear the contents of this control without having to delete the control and add it back with a new instance of the same strict type def.

are you talking about edit mode or run mode?
You could temporarily add a second instance of the typedef (all empty), then change it to a constant. Whenver you need to reset at run time, write the new digram constant to a local variable of the control.

Make sure to click on the array container, not on the array elements.

How to set default value and after that , use it as control

Hello,
Currently i am making motor driver from labview, and i am facing one problem.
When i connect to my board via labview, it will relay last position to global variable. After that, i have to go to loop, where i can send back modified position to my motor control board
In short, i have to control number, but that number default value should be writtem by another function when i start vi.

Default values for confirmation control key

Dear forum
I am using a confirmation control key 0004 Shipping notification (standard SAP) in the Purchase order line item (created with ME21n).
When I enter the confirmation data (with transaction ME22n) in the purchase order line item (confirmations tab), I have to type in delivery date, quantity and so on manually, which is standard.
But, what if I want to copy the original delivery date and quantity from the line item in the order, and use this as default value for the line item confirmation data...is it possible somehow?
The reason why I want to do this is for the user not having to go in and update this date manually all the time, but only when the confirmed dates/quantities differ from the desired delivery date and quantities in the purchase order line item. We are not on EDI or using Inbound deliverys for Purchase orders.
Thanks
Ola

Hi,
The Confirmation is nothing but the acknowledgement.So, its usually entered manuallly by the authorised User allowing follow on documents for Purchase Order.
You can chesk once the customisation of Confiramtion control keys for automatic update indicator.
Yes, you can use User Exit and develop with the help of ABAPERS.
Hope it will help you.

Default value of a numeric control

Hello I want to fix the default value of a numeric control using his node property but I haven't found this attribute. It's possible to fix this value through the node property of a block?
I've tried to fix it, right-clicking on the control....properties....default value....but when I save the vi's and I reopen the vi's, his value has disappeared and value is set 0.
Do you know another way to fix this value?
Thank you in advance
Larson

The default value is only relevant when the VI is loaded into memory, not every time you start running it. Your code is probably changing the value to some out-of-limit value (probably 0 if your calculations are incorrect) and it is coerced to the minimum. If you want a value to remain constant, don't change it.
The answer is simple - DON'T RUN CONTINUOUSLY! If you want something to repeat, use a loop. That way, the value will only need to be read once, when the VI starts running. If this didn't help you, you should post the VI and explain more about your problem.
To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. Here and here are a couple you can start with. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).
