Huge pain Creating a Custom Component with lots of pins

hello
I am trying to create an ATmega 128 MCU in multisim that I plan on using to layout a pcb in utiliboard with. SInce this is just for pcb layout purposes I can care less about adding a spice model. I did the "component wizard" and selected "layout only (footprint)" I chose the TQFP-64 package and all is well. I get to step 4 where i "set pin parameters" and this is where I enter the names of the pins. The problem is that this takes a long long time. I thought there has to be some way to import the pin names from a spreadsheet but I couldnt find any way! The only way I can add them is by selecting each cell in excel and copying then going to multisim and selecting the next cell and pasting. I cannot copy and paste a whole column. This would take hours to do for a chip with over 100 pins. The next step "map pins" takes a long time too. I have to individually click between the cells. Is there any way to map everything at once using the same order?
Also unrelated question. whats the difference between the "TQFP-64" and "TQFP-64L" in multisim? the look identical to me, not sure what the L suffix does.
Thanks

Hi smithman,
It is not possible to import pin names from an excel spreadsheet at this time. I will pass on your concerns to R&D.
The "TQFP-64" and "TQFP-64L" are quite different if you take a closer look at them. It depends on the manufacturer which one they use for their parts.
Sorry I could not be of more help.

Create a Custom Component With Custom Shape

Hi all,
         I want to create a Component that should have a CustomShape.
         I will explain this in detail ,Suppose now we have a Button, Button will be having some Rectangular Shape, But in my Case i dont want this    Rectangula Shape, I will be giving x and y positons Depending on that positon It has to form a Component.
         Any Help is Greatly Appreciated.

Even if you use transparent images, you will still end up with a rectangular bounding box.
You can use programmatic drawing and get a shape that does not involve a rectangle:

Creating a custom component in multisim using *.lib and *.olb files

i have *.lib and *.olb files for a pspice model. which file i have to you while creating a custom component in multisim.

Hello,
Thanks for your question. In order to create simulatable custom components in Multisim you need a SPICE model (Multisim can also understand PSpice Models). The file format for SPICE model can be different according to the manufacturer, for instance: *.cir, *.lib, *.llb. At the end of the day these files are text files that you can open with a text editor, therefore, you can simply copy and paste the model in Multisim.
Here are two good resources on component creation:
Component Creation 101
Creating a Custom Component in NI Multisim
When you reach the step where you need to enter the SPICE model, simply open the *.lib or *.olb file with a text editor, and copy and paste the model.
Hope this helps.

Create complex custom component

Hi everyone!
I'm trying to create my own custom component in JSF. However I have several questions :
- It is not mandatory to create a renderer class, right ? the component can draw itself ?
- How can I create a custom component which would have several "values" inside ? for example let us supppose I want to create a custom JSF component to enter a IBAN. The IBAN is divided into several parts : BBAN, country code, key, Bank adresse,... but any tutorial I've found explain how to create a input component with only one simple value (for example the classical "CreditCardInputComponent").
Josselin

Hi,
did you find a solution for your "composite" component problem?
I am also trying to create a custom component that contains several standard jsf components such as HtmlCommandLink and HtmlInputText.
I build all the standard components within my component programmatically using things like:
HtmlCommandLink link = (HtmlCommandLink) application.createComponent(HtmlCommandLink.COMPONENT_TYPE);
Also at the beginning of the encodeBegin I clear all children from my custom component using getChildren().clear()
and rerender the component based on my new internal model which I updated during the previous decoding of my component.
As a simple jsf custom tag it works ok, however, I am facing deep problems with action events as soon as I use the component within a jsf HtmlDataTable tag.
Am I missing something here?
Any ideas? Help is really really appreciated. This different behavior in different contexts is slowly but constantly driving me nuts.
cheers

Is Creating a Custom Component and Custom UIComponent are same in Flex ??

Hi ,
I am getting confusion in the terminology of words with respect to Custom Components .
Please let me know whether Creating a Custom Component and Custom UIComponent are same in Flex ??
Because i have created some Custom Components based on Form Container based on my business screens .
Does they both Custom Component and Custom UIComponent mean the same ??
Please tell me .
Thanks in advance

There seems to be a little confusion here. Think of it this way:
A basic UIComponent by itself is not visible; you can add something you can see to it to make a visual custom component. For example, a ComboBox component is a UIComponent with a ComboBox added to it.
The UIComponent is the lightest weight component available from which you can create other components. I use it as the base for custom components that the user cannot see, like a data manager.

Custom Component with xfaForm input

Hi. I'm trying to create a custom component that takes as one of its inputs either an xfaForm, a Document containing XML, or an xml variable. So my service method has a variable called data which is just an Object. When I pass in the xfaForm I get a class cast exception when casting the object to the XFARepositoryFormInstance class. I even print out the object and it shows me that its an XFARepositoryFormInstance. Do I have to do something special to work with an xfaForm inside the component? It seems like some sort of class loading issue or something.
I'm stuck. Anybody have thoughts?
Thanks,
Bryan

I'm unstuck :) The key to getting this to work is to import the packages you are going to use in your component.xml.
So, for me..I had to add the following:
        com.adobe.idp.workflow.dsc.type
        com.adobe.idp.taskmanager.form
        com.adobe.idp.taskmanager.form.impl
        com.adobe.idp.taskmanager.form.impl.xfa

Is there a way to create a custom screensaver with pics/slides that display for different amounts of time?

Is there a way to create a custom screensaver with pics/slides that display for different amounts of time? Or even add a "video slide" into the screensaver?
My business has 3 TVs displayed in our lobby, each with its own apple TV and they are all linked to the same photo stream. Currently the Atv screensaver displays the photostream pictures of our products for the default 3 seconds. We just added pics/slides that now display messages and useful info for our customers but I want that info to be displayed for a longer period of time than the pictures to give people a chance to read it.
I tried using flickr and powerpoint as a work around but no luck. I created a slide in powerpoint with play length of 15 secs and saved it as a wmv file. I added that file to a "screensaver" set in flickr and pointed the Atv screensaver to that flickr set. It still displays everything, pics and the wmv file at the default 3 sec.
I know I can increase the duration of all pics in the screensaver to display for longer but the goal is to have the pics display at 3 secs and the info slides to display at 15 secs.

Welcome to the Apple Community.
No that's not possible.
If you have any suggestions that you think might enhance the Apple TV you can send Apple your feedback here

I am changing from Word to Pages. I have created my custom template with all my styles etc and that is what comes up when I go for a New Document. Fine. How do I get it to use the same Custom Template when I use Pages to open a Word document?

I am changing from Word to Pages. I have created my custom template with all my styles etc and that is what comes up when I go for a New Document. Fine. How do I get it to use the same Custom Template when I use Pages to open a Word document?

The template is a document in itself, it is not applied to an existing document whether it is a Pages document or a Word document converted to a Pages document.
You would need to either copy and paste content, using existing styles, or apply the styles to the converted Word document.
You can Import the Styles from an existing document and those imported Styles can be used to override the current document's styles:
Menu > Format > Import Styles
The process is simplified if the styles use the same names, otherwise you will need to delete the style you don't want and replace it with the one that you do want when asked, then the substitution is pretty straightforward.

Is it possible to create a customer master with different address

Hi Gurus,
Is it possible to create a customer master with different address as we maintain in SAP CRM.
Kindly help me onthis issue \
Regards
Kannan

Hi Kannan,
There are no multiple addresses but you can use multiple unloading ponts for the same address for the ship to Party.
So when you create a Sales order the system will give a pop up with the unloading points allowing you to select the desired one.
I hope I understand your query correctly.

How to create a text Component With Certain Properties

I need to create a text component with the following properties:
Has Capability to be italic, right/left aligned, have different background / foreground colors, and most importantly, the ability to have a fixed width and a height that is set by the amount of text in it (ie line wrapping expands the field vertically).
It should be a simple exercise, but I cannot seem to figure out how to do it.

Here is the correct syntax :
private static JEditorPane constructPane(String text, int normWidth, int normHeight, boolean rightAlign, boolean italic,boolean isWhite) {
          JEditorPane pane = new JEditorPane();
          pane.setEditable(false);
          pane.setContentType("text/html");
          pane.setText(
               "<html><head></head><body>"
               + (italic?"<i>":"")
               + "<table><COLGROUP><COL width=\""+normWidth+"\"><THREAD><tr><td valign=\"top\" align="+(rightAlign?"\"right\"":"\"left\"")+">"
               + text+"</td></tr></table>"
               + (italic?"</i>":"")
               + "</body></html>");
          pane.setSize(normWidth,normHeight);
          if(isWhite)
               pane.setBorder(BorderFactory.createCompoundBorder(BorderFactory.createMatteBorder(1,0,1,0,Color.WHITE),BorderFactory.createEmptyBorder(0,1,0,1)));
               pane.setForeground(Color.WHITE);
          else {
               pane.setBorder(BorderFactory.createCompoundBorder(BorderFactory.createMatteBorder(1,0,1,0,Color.BLACK),BorderFactory.createEmptyBorder(0,1,0,1)));
               pane.setForeground(Color.BLACK);
          return pane;
     }

Custom component with additional tags

Hi. I need to write complicated custom JSF component.
I know how to write simple custom components, and receive String variables from tag attributes e.g.
https://github.com/devalentino/temp/blob/master/src/main/java/net/monopolyclub/components/component/UserData.java
But now I need to write custom component with additional tags (for example like dataTable and column tags).
How can I write such component? How can I receive collections in my component? How can I work with additional tags in my component.
for example I need something like:
<m:chat>
     <m:tab value="#{UserList}" />
     <m:message value="#{MesageMap}" />
</m:chat>
where UserList - Collection with current users and MessageMap is Map with User as key and message as value.

Iam using pt:ptdata.joincurrcommunitydata
here is some code
<pt:ptdata.joincurrcommunitydata pt:id="menutabsjoin" />
<pt:logic.foreach pt:var="temp2" pt:data="menutabsjoin">
<span class="CommunityPage">
<pt:core.html href="$temp2.url" pt:tag="a">
<pt:core.html pt:tag="img" src="$temp2.img" alt="$temp2.title" border="0" align="absmiddle" height="$temp2.imgheight"      width="$temp2.imgwidth" />
                    <pt:logic.value pt:value="$temp2.title" />
                         </pt:core.html>
                         </span>
                         </pt:logic.foreach>
But the URL that is generated is not having the CommunityID, hence it errors out saying object not found.
Any help would be appreciated?
Thanks

Creating a custom component

I am creating a custom component that is based on Canvas.
I am trying to add this component as a child of another
component like that:
myCanvas.addChild(myCustomComponent)
addChild function expect ObjectDisplay in its argument and
not a Class. I am little confused. If I am creating a component
that base on Canvas isnt it inherited from ObjectDisplay?
please help.

I actually figure it out. Thank you!!!
here is what I am trying to do.
1. creating component_A based on Canvas
2 in my Application I have Canvas_B
I wanted to add component_A as a child to Canvas_B
solution:
Canvas_B.addChild(new component_A ())

Creating an IBase Component WITH Connection Object (ISU_CONNOBJ)

Hello
I want to create an IBase Component with relation to a Connection Object. I am able to create the first one (IBase Component) but I do not know how to create a Connection Object for the newly created IBase Component.
I am doing everything using the BOL framework and was unable to find a proper relation from IBase Component or Product to Connection Object.
Can you help me out?
regards
Mateusz

Solved!
Apparently after creating new IBase Component and new Product (assigned to the newly created IBase Component) it is required to execute transaction save and commit for the object of newly created Product. After that system sees newly created objects.
Required code (after creation of a new Product):
DATA:
lo_core TYPE REF TO cl_crm_bol_core,
lo_new_product TYPE REF TO cl_crm_bol_entity,
lo_factory TYPE REF TO cl_crm_bol_entity_factory,
lo_transaction TYPE REF TO if_bol_transaction_context.
lo_core = cl_crm_bol_core=>get_instance( ).
lo_factory = lo_core->get_entity_factory( 'Product' ).
lo_new_product = lo_factory->create( )
lo_transaction = lo_core->get_transaction( iv_entity = lo_new_product ).
lo_transaction->save( iv_force_save = abap_true ).
lo_transaction->commit( ).

Help,Help me!   I want to create a custom component

The first, I'm a chinese,my English is very poor.Maybe I make so many mistakes.so
I say sorry for you.
I want to create a custom component so I research the Java.awt.Component .but I don't understand that the class has a method-------dispatchEvent(AWTEvent e).I want to know what invoke this method and when invoke?
thank u

I believe ( believe mind you )
that the method:
public final void dispatchEvent(AWTEvent e)
Dispatches an event to this component or one of its sub components. Calls processEvent before returning for 1.1-style events which have been enabled for
the Component.
Parameters: e - the event
Is used to send an Event message to This component from another
like :
Say you have 'MyComponent1' sending Events to MyComponent2
AWTEvent e = new AWTEvent( blah whatever.......);
MyComponent2.dispatchEvent( e );
and then the Event Handlers on MyComponent2 if any will recieve 'e'
You Probably don't need to modify this behaviour
I assume you are doing something like
public class TestComponent extends Component
private int MySpecialExtraValue;
public TestComponent()
     super(); // like : new Component()
     MySpecialValue = 5; // Just an example
// Override a Method in Component just as an example.
public String getName()
   String S = "I am a Custom Component";
    return S;
//Another override example
public void repaint()
     System.out.println("repaint() was called");
     super.repaint(); // use the original Component Method
     // blah do own stuff
}Override any methods that you need to get the required behaviour that you want...
I hope this is a help........
