About unsigned types

I find that there are no unsigned types in Java, and I wonder why it does not provide
any unsigned types.
Now I am reading a file generated by C programs, and some of them may return negative
bytes rather than positive.
What I have done is to do some convertion like this
int data = ((byte)signedByte+256)%256I wonder if this is a stupid way to get the right data. Any suggestions are appreciated!

hi paulcw
I tried FileInputStream, but it still returns negative
value.Well, it returns a -1 at end of input, but otherwise it only returns positive numbers. At least that's what happened when I tested it. And not only that, but it makes no sense for it to return any negative numbers for the bytes it reads, because if it did, using -1 as an end-of-input indicator wouldn't work.

Why is there no unsigned type is java?

Just wondering? Why no unsigned int or unsigned long? I have often used these in the past but java requires me to do some clever stuff to get over the limitation.

i found this on the net somewhere. it doesn't mention anything about java but it does seem to fit the typical "don't include anything that can be confusing or misunderstood" mold that java utilizes:
"One problem is that unsigned types tend to decrease your
ability to detect common programming errors. Another is that
they often increase the likelihood that clients of your classes
will use the classes incorrectly.
Consider first error detection. Suppose a programmer defines
an Array object as follows:
int f(); // f and g are functions that return
int g(); // ints; what they do is unimportant
Array<double> a(f()-g()); // array size is f()-g()
There�s nothing wrong with this definition for a, except for the
possibility that the programmer writing it made an error. Instead
of the size of the array being f()-g(), perhaps it
should have been g()-f(). Or maybe it should have been
f()+g(). Or possibly it should have been f()-g()+1; off-byone
errors are certainly common enough. Heck, it�s even possible
that f()-g() is correct, but f() or g() is returning a
bad value. Any of these scenarios could lead to the Array
constructor being passed a size that was less than zero. As
the author of the Array class, there�s no way you can keep
clients from making mistakes such as these, but you can do
the next best thing: you can detect such errors and act on
them.
Well, actually, maybe you can�t. You can�t if you declared Array�s
constructor to take an unsigned value, because if a
negative number is passed to a function as an unsigned, the
number seen by the function isn�t negative at all. Instead, it�s
a very large positive number. As a result, you�d have no way
within the Array constructor of distinguishing between a
large, but valid, positive size value and a large, but invalid,
positive size value arising from passing in a negative number.
Hence, you�d be unable to detect programming errors that result
in negative array sizes being requested. Because such errors
are not uncommon, this makes your class easy to use
incorrectly."

According to:
http://en.community.dell.com/support-forums/desktop/f/3515/p/19351107/19767627.a spx#19767627
It has DVI ports. This means you are best to use an adapter that supports DVI. Note there is no audio that carries over DVI. What you need is a mini-Displayport to DVI adapter, and the proper DVI cable. Since Dell doesn't have the specs, you'll need to tell us if you have pins or holes, and how many are grouped.

Documentation about variable types & their processing in i_step = 1, 2 etc.

Hello experts,
is there any documentation about variable types and their processing in i_step = 1, 2 etc.? I know there is note 492504 "Dependent customer exit-type variables", but I don't understand, whether a variable which is NOT "Ready for input" will be processed in i_step = 1 or not (quote of SAP library: "i_step = 1: Call takes place directly before variable entry."). I experienced coincidentally, that some variables not "Ready for input" will be processed there and some not.
Furthermore it is an error, isn't it? Why has a variable without input possibility to be processed before input? Is this really the case?
Confused, any hints are welcomed!
Regards M.L.

for I_STEP = 1
Call before the variable screen .
for I_STEP = 2
Call after variable entry. This step is only started up when the same variable is not input ready and could not be filled at I_STEP=1.
for I_STEP = 3
In this call, you can check the values of the variables. Triggering an exception (RAISE) causes the variable screen to appear once more. Afterwards, I_STEP=2 is also called again.
for I_STEP = 0
The enhancement is not called from the variable screen. The call can come from the authorization check or from the Monitor.
There is a good HOW to Guide which explains the importance of I_STEP :

How could I retrieve metadata about Array Type and Table Type?

I use DatabaseMetaData.getUDTs() method for obtain metadata about Object Types, but this method doesn't work with Array Type and Table Type.

JJ,
Go into the diagrams of the DBTools List Columns and DBTools Get Properties respectively. When you inspect this diagram, you will see the raw ActiveX properties and methods called to get the size information. The value of -1 means the requested recordset is already closed. This is the sort of thing that is controled by the driver (ODBC, OLE DB, Jet, etc) you are using. Notice that you can right click on the property and invoke nodes and get more information about these specific items directly from the ADO online help.

Problem about Valuation Type For MRP

Dear all,
I am managing our materials by valuation type.
But, when I run MRP for these materials, I do not know which specific about valuation type.
Can you help me?
Thanks all
TINDT

As per my best knowledge in standard system you cannot force MRP to manage (plan) your goods based on valuation type.
In case of configurable materials you can do separate planning:

A question about item "type and release" of source system creation

Hello expert,
I have a question about item "type and release" of source system creation.
As we know,when we create a web servie source system,there will display a pop-up which includes three items as "logical system","source system"and "type and release".
About the item "type and release",when we push "F4" button,there will be three default selections as below:
"ORA 115     Oracle Applications 11i
TLF 205     Tealeaf 2.05B
XPD 020     SAP xPD".
Who can tell me when and how should I use the three selections.
And also I attempted to input the item by some optional letters except the default three selections and it seems that I can input it freely.
Thank you and Best Regards,
Maggie

Hello DMK,
Thank you very much for your answer.It is very helpful for me.
Can I ask you further about it?
I got that it is a semantic description item.
You said the default selections are set by our basis people.Would you like to tell me how should we creat a new value except the default ones for item "type and release"?Only by inputing the value in the item directly?But you see we canot see the new value item we created by ourself when we push "F4" button next time ,is that ok?Or do we have to ask basis people to define one new value item just like the default seletions before we use it.
Also if possible would you like to describe detail about "This becomes important when you are troubleshooting certain issues especially when RFC connection problems."
Thank you and Best Regards,
Maggie

About value type and key figure type

Hello Gurus,
please explan the different usage of about value type and key figure type. what is the typical values for both infoobjects ?
Many thanks,
Frank

Hi,
0METYPE is a key figure-specific info object usually used to define semantics of the individual business key figures in BW (for example, actual, commitment, plan, target values).
Its a bi specific field which is filled from extract structure field named MEASTYPE table COSR
Refer to OSS Note 523742 for how it is filled and the following link for additiona information.
http://help.sap.com/saphelp_nw70/helpdata/en/91/ddd52b9ef30645a338e28aae443807/frameset.htm
Note 523742 - BCT-CO: BW key figure model and R/3 tables for trans. data
This note provides information on the key figure model in the area of BW Content CO-OM. It also gives an overview of the DataSources for transaction data and the corresponding source tables and value fields in the R/3 System.
The key figure model for currency fields in the area of CO-OM contents affects the following info object of type key figure:
0AMOUNT Amount
The key figure itself does have any business semantics.
The semantics of the individual business key figures in BW (for example, actual, commitment, plan, target values) is determined using combinations of values for the following key figure-specific info objects (see also the account model in SEM-BPS, note 407563):
0METYPE Key figure type
0VTYPE Value type for reporting
--> 0VTDETL Details of the value type
--> 0VTSTAT Statistics indicator for the value type.
For example, using transaction SE16, the possible characteristics of the values of this InfoObject can be taken from the above-mentioned master data tables in R/3.
The business key figures on the InfoCubes of the standard BW content were defined as restricted key figures using this semantics of the key-figure-specific characteristics.
The conversion of the R/3 transaction data in the BW key figure model is carried out in the extractors using the ROMI_GET_VTYPE_AND_DETAIL function module. It primarily happens using the specified conversion tables.
The following dependencies exist for the source tables of the DataSources:
COSP_VTYPE for COSS, COSP, COVP,
COSB_VTYPE for COSB,
BPXX_VTYPE for BPGE, BPJA, BPEE
If an R/3 source record cannot be converted using these tables, it may not be extracted to BW.The application log of the R/3 DataSource transaction RSA3 contains entries for the unconverted values after the test run.(The log function for the CO-OM DataSources was considerably improved by the correction for note 523655).
The application log for the extraction runs from BW can be evaluated using transaction SLG1 (Object: RSAP, object information: RSAP_INFO)
Furthermore, the semantics of a key figure are still determined by the time characteristics and the following key-figure-specific info objects:
0CURTYPE Currency type (for more information, see note 517909),
0DB_CR_IND Debit/credit indicator (for more information, see note 065075),
0VERSION CO version

About Document type: RE vs G2

Dear forummates:
I am working in SD (again), as I have been working in other SD areas in the past, I have a doubt about billing: The standard Return process: In my country every return must be documented with a Credit Note. As far as I have been researching the return process (Doc.Type RE) ends in a Credit Memo. It is required that this process ends with a Credit Note after the Credit Memo?, what depends on?
Tnahks,
Edited by: Francisco Maureira on Sep 22, 2008 3:05 AM

Hi,
As a terminology Credit note and Credit memo both are same and have same treatment in the accounting side. In case of customer returns, credit note is issued to the customer for return material and in case of any excess amount charged the customer then those times credit memo is issued.

Java5: Can't find a way to get rid of warnings about generic types

Hi all,
i have this method:
    public static void insert(List list, int index, Object obj) {
        list.add(obj);
        int j = list.size() - 1;
        for (; j > index; j--) {
            list.set(j - 1, list.get(j));
        list.set(index, obj);
    }I get 3 warnings. All about:
Type safety: The method add(Object) belongs to the raw type List. References to generic type List<E> should be parameterized
I can't find a way to rewrite this method (Java5), that i get no warnings compiling it and calling it with:
List<AnyClass> list = new ArrayList<AnyClass>();
list.add(new AnyClass());
AnyClass ac = new AnyClass();
insert(list, 0, ac);May be you know another way to insert an element to a List?
Thanks

Never tried it and do not have 5.0 installed to test
it, but what if you define the ArrayList as follows?
List<Object> list = new ArrayList<Object>();
That should get rid of the warnings.

Clarification sought about Application type and library availability

I am new to Adobe's product line and am confused about something and would be grateful for some clarification.
In Flex Builder 3 when creating a new Project, there is an Application type radio button:
O Web application (runs in Flash Player)
O Desktop application (runs in Adobe AIR)
Is my understanding correct that if I choose "Web application", classes identified in the documentation as "AIR only" (e.g. HTMLLoader class) will be unavailable to my app?
Here's the source of my confusion. The class is called flash.html.HTMLLoader and the class is found in the flash.html package, but the documentation reads "(AIR only)".
Do I have to choose "Desktop application" when creating the new project if I want the app to have access to the HTMLLoader class (and others marked "AIR" in the docs)?
Thanks

Yes, that's exactly right.
I assume the source of the confusion is that the "AIR only" classes are still in the flash.* package. In the early days there was some discussion back and forth about the appropriate place to put AIR only classes. In the end it was decided that they would be in the same top-level package as the Flash Player classes.
(To add to the confusion, there is also an air.* package. That package contains classes that are AIR-only but are not built-in to AIR. In other words, they're additional code libraries that make certain functionality easier, but they're written in ActionScript and run on top of AIR just like any ActionScript code you write, rather than being part of the AIR runtime.)

Explain about Data Types INT1, INT2, INT3, INT4 & NUMC

could anyone explain about the data types and give examples.

INT1: 1-byte integer between 0 and 255. The length is set to 3 places for this data type.
INT2: 2-byte integer between -32767 and 32767. Fields of this type should only be used for length fields. These long fields are positioned immediately in front of a long field (type LCHR, LRAW). With INSERT or UPDATE on the long field, the database interface enters the length which was actually used in the length field. The length is set to 5 places for this data type.
INT4: 4-byte integer between -2147483647 bis 2147483647. The length is set to 10 places for this data type.
NUMC: Long character field in which only numbers can be entered. The length of this field is limited to a maximum of 255 places.

About Chart types in IChart

hai,
Can some one plz explain me what is the need of going for Group Bar,Pie, Regression , Coustom Charts in IChart and
im trying to plot Custom chart type with Tag Query values but iam not getting that chart with the TagValues
plz can u tell with which query template we can plot the Custom Chart
Thanks &Regards,
Apsara

Hi Apsara
Barchart: Bar charts are used for comparing two or more values.
Grouped bar chart: It is another type of Bar chart, with data values ordered by tagname/dataset, then by observation.
Pie Chart: It is circular chart and it is divided into sectors.
To see these charts:
http://localhost/LighthammerCMS/Help/Applet_Reference_Details/Applet_Overview.htm
To get info about other charts see this thread:
Regarding information about Chats
For custom chart:
When there is need to represnt diffrent type of datas like line chart and bar type chart in the same graph use the custom chart. To get the chart type, Go to the pen details tab and change the pen type from default to required type.
Hope this helps you.....
