How to make components appear and disappear dynamically.

So I admit I am from the HTML world and have been able to
dynamically control divs to make them visible and invisible, as
needed. How do you do that in Flex/Flash?
I have tried the "visible" attribute, but the component takes
up the same space when invisible leaving a big hole in the page --
very surprising. I have changed the height and width to zero (which
works) but have not been able to restore the size (since I want it
to be width=100% and it is expecting a number, not percentage.
So how do you implement hidden divs in Flex.
Thanks.
Mike

In Flex, there is a separation between "is this component
visible" vs. "does this component take screen space." Similar to
the difference in CSS between "mydiv.style.visibility = 'hidden'"
and "mydiv.style.display = 'none'".
In Flex:
// make it invisible
mything.visible = false;
// make it not take up space onscreen
mything.includeInLayout = false;

              Write the follwing code in WDDOMODIFYVIEW method to create a Dynamic ROADMAP and also create an attribute of
               type string to control the selection of steps in road map.
method WDDOMODIFYVIEW .
data : lr_ele type ref to if_wd_view_element.

data : lr_flowdata type ref to cl_wd_flow_data.
CALL METHOD view->get_root_element
    receiving
      root_view_element = lr_ele.
lr_container ?= lr_ele.
CALL METHOD cl_wd_road_map=>new_road_map
EXPORTING
    id                       = 'ROADMAP'

endmethod.
Then you can use the context attribute to navigate between the steps and do respective actions.

How to make Field "Period/Fiscal Year" dynamic in the program variant

HI All,
We have program called "RCRM_FM_ACL_ACCRUAL_RUN" which is used to calcukate accruals in CRM. This program has got a field "Period/Fiscal Year".
We want this program to run every day at specific time. So we have created a variant in order to schedule a job with program so that it runs every day and calculates the accrual.
when we create variant we need to maintain some values in the variant like fund plan id in fund plan id field and period/year in "Period/Fiscal Year". Normally for date field we have an option to make a field dynamic by selecting value "D" (Dynamic) in selection variable, so it takes date every time as current date automatically and we do not have to change it every day.
But in program *"RCRM_FM_ACL_ACCRUAL_RUN",* I could not find the option "D" for the field "Period/Fiscal Year". Because of this we have to change the "Period/Fiscal Year" manually every time when ever period/year gets changed. we want this to be done automatically.
Can any onet tell me why we are not able to find the optin "D" (Dynamic) in the program "RCRM_FM_ACL_ACCRUAL_RUN". Do we need to do any settings for that.
or
Is there any other way to full fill my requirement i.e period/year get updated automatically with current period/year every time when period/year gets changed.
Thanks in advance,
JM.

Hi,
Using function-modules "RS_VARIANT_CONTENTS" and RS_CHANGE_CREATED_VARIANT and table tvarvc, you can make your variant dynamic. You just need to write a small piece of code using these FMs.

How to make Visible and Invisible using a Button?

hi!... I've a Text3D using Oriented3D object and I would like to know how to make it visible and invisible by clicking a button.
I know there is a function, setVisible() in RenderingAttributes, which can be set by the object's Appearance.
Since I want to use a button to change the object's appearance, I need to change it in the button's actionPerformed function, but it has thrown an exception:
"Shape3D: no capability to set appearance".
I'd tried using those setCapability flags... but still nothing...
Could someone help me please?...
Thanks

When you create Shape3D, setAppearance to it and
setCapability(ALLOW_APPEARANCE_READ).
For the Appearance, you should setCapability(
ALLOW_RENDERING_ATTRIBUTES_READ).
For the RenderingAttributes, you should setCapability(
ALLOW_VISIBLE_WRITE).
So in the button event handler,
shape.getAppearance().getRenderingAttributes().setVisible(true/false).
Now you can control the visiblity of Text3D

How to make fields invisible dynamically in standard transaction?

When we visit T-Code FB60 there are tabs like Basic data, Payment , Details ,Tax ,Notes ,Local Currency.
In the Tax tab there are fields like Tax code, Rep. Date etc.
The Rep.Date has value from BKPF-VATDATE and value for tax code from RTAX1U12-MWSKZ.
The requirement is that in Tax tab if value for tax code is not selected then the Rep. Date field should become invisible i.e., if tax code value is empty then the Rep. Date field should become invisible dynamically.
Is there any BADI/Enhancement Spots to achieve this requirement?

1.In designer on tools menu you have level security. Add what you want objects or groups or users level security.
2.In CMS Select the option universes then provide the security for the object level.
3. you create the below variables :
if CurrentUser()="@Varaible(BOUSER)" then " " else [Dimension]
Hope this is what you are looking out for.

Use a calculated attribute (read-only, type=Visibility) and implement the get-method like
WDVisibility getGroupVisibility(...)
return wdContext.node<TableDataSource>.getLeadSelection() == IWDNode.NO_SELECTION
? WDVisibility.NONE : WDVisibilty.VISIBLE;
Bind the "visible" property of the group to this attribute.

How to make fields required in an updateble multi line form?

How to make fields required in an updateble multi line form?

You need to create a validation item that is triggered when the user clicks the submit button.
Set the validation type to "Function Returning Error Text".
Then add your validation into the "Validation Expression 1" field. Something like:
BEGIN
FOR I IN 1.. HTMLDB_APPLICATION.G_F02.COUNT LOOP
IF HTMLDB_APPLICATION.G_F02(I) IS NULL THEN
RETURN 'Please enter in a value for xxxxx on line ' || TO_CHAR(I,'0');
END IF;
END LOOP;
RETURN NULL;
END;
As long as the function returns a string, an error is generated - as there is no single field where this error can be displayed, it will need to be displayed "On Error Page".
If the return value is NULL, then the fields are valid and the submit process can continue.

How to populate fields "DocEntry" and "DocNum" in UDT? Those are not UDF.

I created a UDT with document type. When I populate the data, I don't know how to populate fields "DocEntry" and "DocNum". Those are not UDF. Here is my coding. Can somebody help me out?
Dim objUserTable As SAPbobsCOM.UserTable
                    objUserTable = objSBOAPI.oCompany.UserTables.Item("AIT_POSTRANS")
objUserTable.UserFields.Fields.Item("DocEntry").Value ="1000"
///////////// Error here "DocEntry" is not a UDF
                                       objUserTable.UserFields.Fields.Item("U_TrnsType").Value = "4"
                        objUserTable.UserFields.Fields.Item("U_CardCode").Value = objRecord.Fields.Item(0).Value
                        objUserTable.UserFields.Fields.Item("U_ShpBrnch").Value = objRecord.Fields.Item(1).Value.Replace("'", "")

Currently versions of the SDK (SBO2005A SP01, SBO2007A, SBO2005B, SBO2007B) does not support Data Support of UDO-tabeles using the DI-API... That means that you can only add data to such tables using the GUI,,,
This is currently a huge problem and the number one DI-API Development Request. The status with SAP is that this will become part of the SDK in SAP Business One 8.8 (the next major release), but 8.8 does not yet have a shipment date (My guess is that it will be 2009 before we even see it in rampup)...
I know some people have experimented with writing direct SQL to such tables and know it can be done, but be aware that SAP does NOT support it!... Personally I've never done it for that reason althoug it would have been nice to do if some situations...
Sorry I could not give anything better...

How to make the dblink and what is the use of this

plz any body tell me "how to make the dblink and what is the use of this"
sujit

Do you understand how to make the Slider work using code to read its value? You will need to look into that in order to do this.
What you can do is have the yello rectangle be a movieclip that sits over the red rectangle and use the Slider to control the yellow rectangle's alpha property from 0 to 1. That way the yellow will gradually fade as you slide.
What you will then need to do is figure out how to make the number of dots that appear reduce from 15 to 8 over the same range of the slider. You need to use the fractional value from the slider to decide how many dots either appear or do not appear.
You should not start new postings for the same topics that you arlready have postings for. Doing so in the future might result in them being removed.
