  How one accesses a function from another class?

  Let's say I have a file called .as hand. My flash file uses this as this is the main class to make it work when you test the program. Let's say I have another class named Test that looks like this:

• FRM-92101 happens when I open one form from another and then close it.

  FRM-92101 happens when I open one form from another, check something, display a message to the user and exit the screen to the previous shape.
  
  Version of forms: 10.1.2.0.2. Java: 1.6.0_23. Browser: IE6
  
  When I put forward two messages of 'EXIT_FORM', all right and the second form is closed again to the first shape just like I wanted.
  In 9.0 forms, it did not.
  
  It has to do with the fact that I use JRE instead of JInitiator?
  Thank you.

  Take a look by using the built-in NAME_IN forms. You will find the NAME_IN function takes a STRING as parameter. Change your code to:

  IF NAME_IN('SYSTEM.CURSOR_ITEM') IS NOT NULL THEN
     SYNCHRONIZE;
  END IF;
  

  Hope this helps,

• calling a method from javascript bean

  Hi forum,
  
  I was wondering if it is possible to call a method of bean managed from javascript. Why do I need it? Because I want to implement a simple javascript and light confirm dialogue resulting (Y or N) determines if the call or not a method that could achieve a vo. To be more precise, I hava a table only reading and I want to give the user the option to select a single line and remove it without taking to another page but confirming a javascript dialog box.
  Thank you very much in advance.

  Yes,

  .. You should forget about it. 10.1.3 doesn't have a callback method in controlled beans. In theory, you can create a filter for the faces servlet and pass a parameter of specific application as a flag with the request, so the filter can attempt to access the bean managed and put some information below. However, on the client side you would issue such a XMLHttpRequest

• How to call a dll from another dll functions

  Hi, can someone please tell me some examples or instructions on how you go about calling functions from a dll from another dll including the IUR. The two DLLs were created with labwindows cvi.

  Thank you!

  Hi Sinnas,

  You mention that you use a UIR.  A DLL does not have a file UIR as part of it.

  DLL1

  Instead, when you build the DLL first, we'll call it DLL1, you create a header or the files that contain functions that you want to the client code to call.  When you build DLL1, you must export the file DLL1 function for his client to call code header.  Whatever the calling code is (a GUI or another DLL), you must include in the exported DLL1 project headers AND DLL1 .lib file generated when you generate it.

  DLL2

  DLL2 will contain in its project, the header file exported for DLL1, DLL1 .lib file - that gives it the feature in DLL1.  The code can then call any desired DLL1, but as DLL1, you should now have a header file that exports the functions of DLL2 desired HIS client code to call.  When you build DLL2, you create a .lib for THAT DLL file to include in the code of the final customer.

  GUI

  The final customer code will be a few GUI that you create to call DLL2 functions will have the UIR upper layer file.  It will include the exported DLL2 header file and the file .lib DLL2 in his project.  It can then call any function of DLL2.  It is the most clean way to have 2 dll working together.

  NOTE: You can create a GUI to test the lower level DLL1 functions before placing DLL2 in the system.  In fact, it's a good idea to do it - you want to make sure your lower level DLL1 code works properly before construction above it.

  Simple diagram

  Client code (calls to functions of the DLL2 header files) exported

  --------------------------------------------------------------------------

  DLL2 (DLL1 function calls exported in header files)

  --------------------------------------------------------------------------

  DLL1<--------------------  you="" can="" also="" create="" a="" gui="" that="" only="" calls="" dll1="" exported="" header="" files="" to="" test="" out="">

  A suggestion... I create my dll in debug mode and use them to test my code.  But I also build as static libraries.  When I do the final version of the system, I use static libraries.  They are built with the final executable and don't require additional files to install as do the dll.  When you install your system with DLLs, you must include all THE dll and they must be installed in the folder Windows/System32 of the target computer.

  I hope this helps...

• pushScreen does not not when calling another method of another class

  Hi all

  Earlier today, I was able to get a program that is running and I was actually pretty happy with it despite the fact that he has a lot of bugs.  However, in attempting to remove bugs and me being stupid and forget to backup my previous code that it no longer works. In any case the line of code that I used was

  UiApplication.getUiApplication () .pushScreen (ScanScreen ());

  ScanScreen is a method that I created in another class.

  Any help is greatly appreciated thanks!

  Thanks for all the help!  I just made a new button and pushed the event from there.  He works for now so thank you again for all the help everyone!

• Populating one table from another table

  Hi Forum...
  
  I'm trying to populate a table from another table using CFQUERY... I have no problem with the selection of data from the original table, but need help to get the data into the new table. I use MX 6.1 and access as the database server.
  The two arrays have domain names identical to the same place, and I don't want to have to code all the column names in the selection and insert command. for example
  
  < cfquery name = "GetData" datasource = 'somename' >
  SELECT * FROM AssetTable1 WHERE BarCode = "123456".
  < / cfquery >
  
  < cfloop query = "GetData" >
  < cfquery name = "InsData" datasource = 'somename' >
  INSERT INTO AssetTable2 (xxxx...)
  VALUES ("#xxxx... #'")
  < / cfquery >
  < / cfloop >
  
  I hope this makes sense
  
  Thanks in advance

  If your tables are identical structures and their columns are of the same type and position, and both tables are in the same database, then put everything in a single query.

  
  INSERT INTO AssetTable2
  SELECT *.
  OF AssetTable1
  WHERE bar code = "123456".
  

  If the columns were in different positions, then you should be listed explicitly in the INSERT and SELECT the parts, but you get the idea.

  INSERT INTO table1 (col1, col2)
  SELECT col1, col2
  FROM table2
  WHERE all that...

• Using a function from another class

  Information: Blackberry JDE 7.1.0

  BlackBerry 9930 Simulator - V 4.0.0.141

  The title of the topic seems simple, but I'm actually trying to use a X of class A function inside a function Y of class B and the GET, the value returned by X to a variable in B.

  Let me start by explaining what I currently have and then go on what I'm doing.

  I am using this class, the code for which I found online, to create a scrollable multi-line textbox.

  public class TextBoxField extends VerticalFieldManager {
  
        //define some variables to be used
        //in the class
        private int managerWidth;
        private int managerHeight;
        private EditField editField;
  
        public TextBoxField(int width, int height) {
              super(Manager.NO_VERTICAL_SCROLL);
              managerWidth = width;
              managerHeight = height;
  
              VerticalFieldManager vfm =
                  new VerticalFieldManager
                    (Manager.VERTICAL_SCROLL);
  
                editField = new EditField(){
                  public void paint(Graphics g) {
                  getManager().invalidate();
                  super.paint(g);
                }
              };
  
              vfm.add(editField);
              add(vfm);
            }
  
        public void paint(Graphics g) {
            super.paint(g);
            g.drawRect(0, 0, getWidth(), getHeight());
          }
  
        public void sublayout(int width, int height) {
            if (managerWidth == 0) {
              managerWidth = width;
            }
            if (managerHeight == 0) {
              managerHeight = height;
            }
            super.sublayout(managerWidth, managerHeight);
            setExtent(managerWidth,managerHeight);
          }
  
        public String getText() {
              return editField.getText();
            }
            public void setText(String text) {
              editField.setText(text);
            }
          }
  

  Then in another class that I created a "Set" function that instantiates the class textbox, to create two text boxes and a richfieldtext, add them to a HorizontalFieldManager and return the HorizontalFieldManager.

   HorizontalFieldManager Set(int set){
          HorizontalFieldManager hr1=new HorizontalFieldManager(FIELD_HCENTER);
  
          RichTextField set1 = new RichTextField("SET " + set + ":"){
              protected void layout(int width, int height)
              {
                  super.layout(75,30);//Width and height according to the button name;
                  setExtent(75,30);//width and height according to the button name;
              }
          };
          set1.setPadding(10, 5, 10, 10);
          TextBoxField set1W = new TextBoxField(40,25);
          set1W.setPadding(10, 5, 10, 0);
          TextBoxField set1R = new TextBoxField(40,25);
          set1R.setPadding(10, 5, 10, 0);
  
          hr1.add(set1);
          hr1.add(set1W);
          hr1.add(set1R);
  
          return hr1;
      }
  

  Now in my main class I call this function to add a 'Set' on the screen using:

  add(Set(1));
  

  For the creation of the 'Set' function instead of using the instance of the textbox class in the main class itself, it is because I will create several 'sets '.

  Now, as you can see, there is a public String getText() function in the TextBoxField() that returns the value of the editField. What I need to do, is to get the value in this field, once you press a button.

  I have the code for the function button, so this isn't a matter of concern. However I do not know how to retrieve the editField value when the button is pressed. I can get the value inside the Set()function, using the:

  String getval = set1W.getText();
  

  but can't reach it from the outside. I don't even know if it's possible in the first. If it is not could someone suggest a way where I could retrieve these values.

  Any help is appreciated.

  Thank you.

  Thanks for the suggestion. I found another workaround solution. Essentially implementation of an array of TextBoxFields and then pass them one by one the "Set()" method

  I tried this at the start before posting here, but due to a careless mistake when you declare the array of TextBoxFields, I couldn't make it work.

  In any case, the topic can be closed now, because the problem has been resolved. Thank you.

• Return one Page to another class?

  Simple question here:

  I have a class that contains my 'main' nagivation pane (menu) for my application.

  For everything that needs to be addded, I have other classes that do all the work (create the page, add content, etc.). The main class, I want to do: navigationPane-> push (classB.createContent ()), and createContent returns a Page object with all the stuff on this subject.

  If I put the return as a Page type, in my header to classB as follows file:

  public:
  Game();
  Page * getPage();

  I have this error in the header file: error: 'Page' does not designate a type.

  Is it possible that I can get this Page object I created in to use in my main class classB, classA? I also tried to use a static variable for the Page, but that no longer works...

  Any help is appreciated, thanks.

  Hello

  Forward-declare the Page in the header file:

  namespace bb { namespace cascades { class Page; } }
  

  And use a display name:

  public:
  bb::cascades::Page *getPage();
  

  Depending on what you're trying to do might be preferable to create a class that inherits from Page and create content in the constructor.

  Adding "using the namespace bb::cascades' would also correct the mistake, but it's not recommended to do this in the header files.

  Also the headers should not be included in any other header files unless that inherit from these classes or their instantiation on-site. Pointers and references may be declared in advance. This will make the compilation faster.

• How to call a method of one class from another class?

  I have two classes, Class1 and Class2 are saying. They are both public. They are located in the same package, and both are important to each other.

  I am trying to call a 2 function in Class1, but I do not know the syntax.

  I tried:

  Class2.godoThisThingNow ();

  But it gave me an error 1061, call to a method not defined.

  What is the correct syntax for this, and it is even possible in AS3?

  Thank you!

  You can call a public in Class1 2 method IF Class2 has access to an instance/member of Class1.

  for example, in Class2:

  var c1:Class1;

  .

  .

  C1 = new Class1();

  .

  .

  .

  C1.somepublicMethod ();
