Working out the Concrete classes of an Interface

Hi all I have an interface e.g. Animal with 3 concrete classes:
Dog, Cat and Bird.
Is there a way of working out that the Animial interace contains these 3 concrete classes in anyway?
Thanks,

First of all, it doesn't "contain" them. The relationship between class and interface is one-way.
You could whip up something that examines every class on your classpath, or a portion of it, and cheks whether it implements that interface. However, this will not work in general, since classes can be loaded from anywhere, and you may not always have the right or ability to list the classes present there, only to request specfic classes by name.

How do you work out the number of days difference between two dates?

I'm running Crystal v12.
We use a date field in our SQL database that we use to store the client's year end date.
As the year end date (date and month) doesn't change for a client, the year end date field in all of our reports is set to just show the DD/MM part. Over the years as new clients are set up we just enter the date and month - the year part is irrelevant although as in all date fields the year is automatically entered.
Doing it this way means that we don't have to adjust the year end year part each year. We just use the DD/MM part.
I need to create a formula that works out the number of days there have been (i.e. the difference) from the current date to the year end date. It MUST EXCLUDE the year however.
For example:
Year End Date = 30/04/03
Current Date = 25/05/10
Days Difference (EXCLUDING year) = 25
Days Difference (including year) = 2582
Year End Date = 31/03/09
Current Date = 25/05/09
Days Difference (EXCLUDING year) = 55
Days Difference (including year) = 420
If you include the year part then working out day difference is simply a case of creating a formula that subtracts the year end date from the current date (CurrentDate - {tblClient.YearEnd}.
HOWEVER I need to exclude the year part.
Can anyone tell me the formula or best way to do this?
Thanks in advance.

Hi
You can try this
datevar e := date(year(currentdate),month({tblClient.YearEnd}),day({tblClient.YearEnd}));
numbervar num_days := datediff("d",currentdate,e)
Create a datevar called e that uses the original month and day numbers for {tblClient.YearEnd} but uses the year of the current date
Then just datediff on e to get the number of days between the two dates
I hope i understand your problem and that this helps

Automatically working out the domain for a cookie

Hi all
          We have a couple of web sites that we want to share cookies between
          we have one site www.mysite.com and another, registration.mysite.com
          If, when I add a cookie and hardcode the domain to '.mysite.com' everything
          works fine. However I would like to dynamically work out the domain because
          we deploy our sites within a number of countries and i dont want to hardcode
          the domain name (eg uk would be www.mysite.co.uk, so the domain would be
          .mysite.co.uk )
          If someone enters www.mysite.com/request.jsp i want to be able to extract
          .mysite.com out of the url and specify it as the domain when adding cookies.
          Does anyone know of any servlet related methods that can get the url that
          was requested - including the server name?
          request.getServerName() wont work because it returns the machine name (ie
          the name of your machine within a network). request.getRequestUrl() also
          wont work for the same reason.
          If anyone knows how i would extract the url the user typed in then that
          would be great
          Thanks

Designing a banner stand: Is there a easy way to work out the recommend margins / bleed?

So its my first time creating a banner stand and something of larger scale. I was wondering if there is a certain way to work out the recommended margins for the size of the document? Or should i simply do it by eye. The banner dimensions our 800m x 1200mm.
Also any other tips for creating larger document would be appreciated.

It sounds like the same product that we do a lot of here. There's no technical reasons for a particular margin, as they can be full bleed (print right to the edge), so it's a subjective design decision.Take into consideration the content and the context. It could be a something with little content, intended to draw people from a distance (larger margins), or it could be something with a lot of content that will be read from a short distance (smaller margins).
I tend to do these as 1:1 scale, but bear in mind that InDesign's Optical Kerning will be too tight when you do this.

Java Time Work out the difference

Hello. This is my first forum here. I am having difficulties in solving this code below:-
If one data has a time of "14:00" - If this data went over the today's time so we would say it is too late. If this data is started before the today's time. It is done.
Calendar TodayDate = Calendar.getInstance();
SimpleDateFormat formatTime = new SimpleDateFormat("HH:mm");
String timeNow = formatTime.format(TodayDate.getTime());
System.out.print("Time Now is " +timeNow);
String dataTime = "13:45";
System.out.print("\nData Time is " +dataTime);
if (dataTime > timeNow) {
System.out.print("Too Late");
if (dataTime < timeNow) {
System.out.print("It is done");
}Basically - the IF statement is wrong as it is String. Need help on how to change the String to Integer or Long (work out the milliseconds) Help would be appreciated

How can i work out the GMT time wherever i am ?

Hi, i'm going crazy with the date/time classes, just can't seem to work it out.
I need to know the current time as a GMT time.
I need to know wherever the program is running, i myself am in Amsterdam GMT+02:00 , my server is located in Canada GMT-04:00 (?)
I parse dates from websites all over the world so i get times in the form of strings of which i know the timezone. I need to store everything in a mysql database and i want the database to contain GMT times only.
I've worked out how to get a string from its timezone into GMT but,
how can i get the current time as GMT ?
somehow i keep getting timeshifts i cannot explain.
this is where i got to:
TimeZone tz_gmt;
tz_gmt = TimeZone.getTimeZone("GMT");
SimpleDateFormat sdformat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
sdformat.setTimeZone(tz_gmt);
Timestamp tsGmtnow;
tsGmtnow = Timestamp.valueOf(sdformat.format(new Date()));
Which is fine if i run it in Amsterdam, it gives me the current date/time in GMT, but on the server in Canada it gives me GMT+4 hours. What am i missing ?

found a workaround,
     TimeZone tz_gmt;
     tz_gmt = TimeZone.getTimeZone("GMT");
     TimeZone tz_can;
     tz_can = TimeZone.getTimeZone("GMT-04:00");
     TimeZone tz = TimeZone.getDefault();
     String Stz = tz.getID();
     SimpleDateFormat sdformat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
     Timestamp tsGmtnow;
if ( "Europe/Berlin".compareTo(Stz) == 0) {
     // i'm in Europe, go from local time to GMT
     sdformat.setTimeZone(tz_gmt);
     tsGmtnow = Timestamp.valueOf(sdformat.format(new Date()));
} else {
     // i'm in Canada, local time IS gmt
     sdformat.setTimeZone(tz_can);
     tsGmtnow = Timestamp.valueOf(sdformat.format(new Date()));
out.println(tsGmtnow.toString());
the default timezone returns either:
Europe/Canada
GMT-04:00
somehow the GMT-04:00 get ignored by the formatter

          new MPC();
}

This portion to be exact. All the buttons work for me except this one. I need to calculate user input and also use the fixed data that can be found in the dblTrmLoanRate array. When I choos to use user input instead, the program either crashes or for some reason uses the year7InterestRateBtn instead.
               if (command == btnCalc)
                    //dblLoanAmount = Double.parseDouble(txtTotalMort.getText() ); // Loan amount
                    //interestRate = Double.parseDouble(txtInterestRate.getText() ); // /100 )/ 12; // Devides rate
                    intRate = (Double.parseDouble(txtInterestRate.getText() )/100 )/ 12;
                    //int intYearsMonths = Integer.parseInt(txtYearsInput.getText() );// * 12; //Multiplies loan length

I was going to leave out the remed portion but thought it might help you with the navigation. I am sorry I did not use code tags, but I am going to go find out what those are and use them in the future.

To find the implementing classes of an interface

Hi,
Does anyone know a function module or class using which I can find all implementing classes of an interface?
Regards,
Sukru

Hello Sukru
If you are working already on SAP releases >= 6.20 then you will see all implementing classes if you display the interface in SE80 (tree display -> subnode of the interface).
Alternatively, you can call method <b>GET_IMPLEMENTING_CLASSES</b> of class <b>CL_OO_INTERFACE</b> (available on >= 6.40, perhaps on 6.20, too).

How to find out the batch class link of the batch record in the MSC3N

Hi,
I would like to know how to pull out the class type and the characteristic value for a batch which is found in MSC3N.
For example, the following is MSC3N screen showing material (INM000000001724945) and batch (A000001117) tie to batch class “XXXXXXXX”.
Hence, I would like to know:
How to pull out the class type and the characteristic value for a batch record which is found in MSC3N? What are the table? The table show in the F1 key is not a table.
There are two batch classes setup in the system “XXXXXXX” and “YYYYYYY”, my question is why system decides to use the batch class “XXXXXXX”? Where is the system setup to determine this?
Thanks
Tuff

Hi
The table MCH1 keeps the information about Material, Batch and Internal object no.: Batch classification (CUOBJ_BM).
The field CUOBJ_BM in MCHA represent the 'Key of object to be classified' (AUSP-OBJEK). The first 18 characters of AUSP-OBJEK.
In CABN (Characteristic) the field ATINN and ATNAM is important. The link between CABN and AUSP is through ATINN.

How to find out the callers class?

Is it possible to find out whats the callers class from within a method without having the caller to pass a reference to itslef?
Ako

There are many posts on the subject. Two things.
1) Yes it's possible by getting a stacktrace.
2) No one should ever want to implement this. It perverts the idea of the language.

Hi All,
I want to know the best way of debugging for the following process:
Create ME22N
went to item level account assignment and selected the cost center.
Got an error message in the status bar
I wanted to find out where the message class is used in the background program
Any help is appreciated.
Thanks

Finding out the actual Class of an Object

I have an AdvancedDataGrid (ADG) where the top level items
are instances of my custom valueObject Class "State". The second
level items are instances of another custom valueObject Class -
"City". When I select an item in the ADG, I want to know which
Class each item is - "State" or "City". Is there some way to find
this out? I'm not looking for how to capture the event, I'm wanting
to find out if there is some function or utility for finding out
the Class of an Object.
FYI, when I capture the event, and pop an Alert with the
following code...
Alert.show(item.constructor.toString());
...I see either "[class State]" or "[class City]". So, I feel
like I'm close...
Thanks.

I just can't work out the variable here!

Hi team,
I have some code that I am trying to put onto 10 different moviclips m1, m2 m3 etc to 10
I have tried to use every hint and bit of code that has been given to me by others here but I just can't get it to work..
I am trying
for (var i =1; i<=10; i++){
trace("m"+i);// this gives me the right result but doesnt work in the code..
I have tried
m[i]
["m"+i]
MovieClip("m"+i)
this.[m+i]
..... and heaps more! I just can't get it to work.
Here is the code I am trying to use this variable on,
Thanks for any help,
sub
m1.minX = 132;
m1.minY = 182;
m1.maxX = 930;
m1.maxY = 720;
// Initialize the circle at a random coordinate within the acceptable range.
m1.x = Math.random() *m1.maxX -m1.minX;
m1.y = Math.random() *m1.maxY -m1.minY;
// Set the velocity of the circle to six pixels/frame.
m1.vel = .003;
/* Initialize the x and y vectors for the circle clip. A "vector",
   in circle case, is a line that both direction (angle) and speed ("velocity").
   Here the direction is either horizontal (x-axis), in the
   case of "vx," or vertical (the y-axis), in the case of "vy."
   So, while it may appear that we're just assigning one number, the
   velocity, keep in mind that we've also determined the direction by
   distinguishing these values as either horizonal ("vx") or vertical ("vy").
   BUT -- while all that is true, it's also cheating a little (remember, this
   is the "simple" version.) The reality is that we're really using 2 speeds
   and 2 directions, where a vector is truly a single direction and single
   speed. See the "complex" version for that execution.
m1.vx = Math.random() * 3;
m1.vy = Math.random() * 3;
// Define an onEnterFrame() method for the circle so that it continually updates
// its position.
m1.addEventListener(Event.ENTER_FRAME, enterFrameHandler);
function enterFrameHandler(e:Event):void {
    // Calculate the new x and y coords for the circle clip on each frame
    // based on what happened in the previous frame (in the conditionals below.)
   m1.x +=m1.vx;
   m1.y +=m1.vy;
    // If the circle is touching the rectangle or is outside its boundaries,
    // change direction.
    if ((m1.x +m1.width/2) >=m1.maxX) {
       m1.x =m1.maxX -m1.width/2;
       m1.vx *= -1;
    else if ((m1.x -m1.width/2) <=m1.minX) {
       m1.x =m1.minX +m1.width/2;
       m1.vx *= -1;
    if ((m1.y +m1.height/2) >=m1.maxY) {
       m1.y =m1.maxY -m1.height/2;
       m1.vy *= -1;
    else if ((m1.y -m1.height/2) <=m1.minY) {
       m1.y =m1.minY +m1.height/2;
       m1.vy *= -1;

The correct way to target instances m1 thru m10 using bracket notation would be...
this["m"+i]
or even more correctly...
this["m"+String(i)]
