How to map C/C++ unsigned char[] to Java

hi all,
I'm using w2k OS.
Given that C code:
BYTE *fBuf;
fBuf = new BYTE[256];
Is there anyone of you know how to pass/map the unsigned char to java?
regards
elvis

why did you classify this as byte? how do you did
that?They probably guessed. It is probably a good guess.
You can use the following to determine the size exactly.
First determine what "BYTE" is exactly. You will have to find that in an include file somewhere. Your IDE might do this for you automatically.
So, for example you might find the following...
typedef unsigned char BYTE;
So then you would know that the type is actually "unsigned char".
Once you have this information you then look in limits.h (this is an ANSI C/C++ file so it will exist somewhere.) In it you find the "..._BIT" that corresponds to the type. For the type given above you would be looking for "CHAR_BIT" (because unsigned and signed chars are the same size.)
On my system that would be...
#define CHAR_BIT 8
That tells you that there are 8 bits in the BYTE value. So now you need to find a java type that also has at least 8 bits. And the java "byte" value does.

How can I get an unsigned char string with nulls from a dll into LabVIEW 6i?

The following ethernet packet data is contained in an unsigned char * string returned from my dll (it's formatted on printing):
Received A 230 Packet On Adapter 0x008F0070
Ethernet Dest: 01.E0.BB.00.00.15 Src: 00.E0.BB.00.DD.CC Type: 0x8868
000000: 01 E0 BB 00 00 15 00 E0 : BB 00 DD CC 88 68 48 41 .............hHA
000010: 00 E0 BB 00 DD CC 80 B3 : 00 00 FF FF 00 02 00 01 ................
000020: 01 00 F0 18 FF 7F 7F FF : FF 7F 7F FF FF 7F 7F FF ................etc., etc.
However, when I read this string into LabVIEW 6i, I only get the following:
01E0 BB
Which is the data before the first NULL or 00 information. I found a "Remove Unprintable Chars.vi" but it
just sees more data before the above string, nothing after, as seen here: 5C30 31E0 BB.
Anybody have any suggestions for how to get the rest of the string? Is there something I can do to further reformat my dll? The dll I'm using is already a wrapper around another dll so I have some flexibility, but the bottom line is, the data I want is in the format of an unsigned char *.

Excellent advice, this mostly works so I have some further questions:
I am just reading network traffic off my ethernet card right now, but here is what I get using my C program to test:

And here is what I get using LabVIEW to call the dll:
0015 00E0 BB00 DDCC 8868 4841 00E0 BB00 DDCC 80B3 0000 FFFF 0002 0001 0100 9600 7F7F 7F7E 7F7F 7F7F 7F7F 7F7F 7F7F 7F00 B405 4300 3300 0000 0000 0000 01E0 BB00 0015 00E0 BB00 DDCC 8868 4841 00E0 BB00 DDCC 80B3 0000 FFFF 0002 0001 0100 9600 7F7F 7F7E 7F7F 7F7F 7F7F 7F7F 7F7F 7F00 F405 1B04 0C04 0000 0000 0000 8000 0000 0000 0000 0800 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000
The first thing I notice is that the first 4 bytes are chopped off, and after about 50 bytes, the data is corrupted until the sequence starts to repeat, but this time it starts with the missing 4 bytes and still corrupts after about 55 bytes.
I am expecting the data in LabVIEW to look very similar to the C data because the network packets I am grabbing are pretty consistant, only a couple bytes will vary between them, not the number I am seeing in LabVIEW.
Another side effect I'm seeing is that I can only run my labVIEW code once, if I try running it again it crashes with failures such as:
memory could not be "read"
For reference, I am opening and closing the network adapter inside the read function of my dll, but the pointer seems like it should be intact...

Unsigned char* to jbytearray

could anyone please tell me how I could convert an unsigned char*, which is just some binary data to jbytearray.
the c++ program is being called thru JNI and hence jbytearray.
or is there a cleaner way to capture whatevr I get from the C++ code, and send it as is into my java module, so I can send it out through a UDP socket?

mlk thank you. i looked at it earlier in the serach results. But i am having second thoughts now. does it have to be so complicated.
how do i make sure that the raw data returned by my C++ code is maintained as is by java module and ushed out of a UDP socket.
what data types should I rely on.
because at the other end of the socket, i have a client which can understand the raw data which was generated by the c++ code at my end.
any kind of suggestion will be a great help.

Mapping struct dataype in C to Java JNI

Do anyone have idea how to map struct datatype in C to Java JNI?
I've got idea and examples of mapping primitive datatype and array in C to Java JNI but none for struct datatype in C?
Hope I can got an example of it! Thanks!!!

The first way - by the book
Read Sheng Liang's book (downloadable from ftp://ftp.javasoft.com/docs/specs/jni.pdf )
In brief - and explaining only the main steps - no detailed instructions - please read the book
You want to return an array of the following objects (they have only primitive data, for easing the explanation)
//-- C++
struct MyData {
    int firstField;
    char *secondField;
//-- Java
public class MyData {
    public int firstField;
    public String secondField;
}in the native Java method "doSomething" of the class MyProgram
public class MyProgram {
    static {
        System.loadLibrary ("myjni");
    public static native MyData[] doSomething() ;
}You will have to call JNI functions for creating the MyData[] array, for creating individual MyData objects, and for setting the individual fields of each MyData object. Very boring indeed.
The second way - the hard one
Instead of returning a Java array of Java objects, study the serialization format of Java, and return a Java array of bytes. Then use ByteArrayInputStream and ObjectInputStream, or DataInputStream, for deserializing the objects you do need to get in your program. It will be slower than creating directly the Java objects in your C++ program, but you can save a few lines of code in your C++ program. (You will maintain the program yourself, don't you?)
The third way - the lazy one
Instead of returning a Java array of Java objects, return a Java String (it could be a XML-formatted string, or a string using delimiters - what you think that is easier to encode in C++ and decode in Java.)
The third way - the better way
Use the SWIG framework ( http://www.swig.org ). Your code will be very maintenable, you will not have to deal with JNI issues (there are lots and lots of JNI details you will have to bother with, solve all that problems with SWIG). Take care with spelling - SWIG is not SWING.

"unsigned char** pImgData" How to call in LabVIEW

HI,
I am calling a DLL in LabVIEW8.5 by using "Call Library Function Node".
I can able to access all the functions and getting exact results.
But for the below function LabVIEW is crashing.
void SFCCU_GET_IMG_RAW_DATA(unsigned long *length,unsigned char** pImgData,unsigned int iCamObj)
According to the doccumentation of the dll provided, pImgData is 1D array.
I tried the same dll in VC++. I can able to acheive the result of he above function properly.
I attached the Call Library Function Node.vi's prototype with this mail what i have done. It seems to be correct.
But i dont know why its crashing. Please tell me wether i am calling properly or not.
if not, kindly suggest me how to overcome it.
Thanks in advance for the help,
Please help me,
Thanks,

Hi Sams,
Can you clarify what you mean by crash? Can you describe what happens? Do you get an error message? Is there anything different in how you are calling the function in LabVIEW versus VC++?
I look forward to your reply to help move this issue forward.

Wrtie unsigned char and unsigned int into a binary file

Hi, I need write some data into some specific file format (.ov2) for other applications to read.
Here is the requirement of the data:
First byte: An unsigned char value, always "2" means simple POI entry
Next 4 byte: An unsigned int value,
Next 4 byte: A signed integer value.
Next 4 byte: A signed integer value
then next : A zero-terminated Ascii string
Here is my code:
                   String name = "name";
                   byte type = 2;
                 int size = name.length() + 13 +1; //1+4+4+4 and there is a 0 at last
                 int a = 1;
                 int b =2;
                 ds.writeByte(type); //1 byte, need save it as unsigned char
                     ds.writeInt(size); //4 //need to be an unsignged int
                     ds.writeInt(ilont); //4 //signed int
                     ds.writeInt(ilatt); //4 //signed int
                     //write zero-terminated ascii string
                     for(int n=0; n<name.length(); n++){
                          ds.writeByte(name.charAt(n));
                     ds.writeByte(0);                    This code could not get the correct result and I think I must do some sign to unsign conversion, but I don't know how to do it. Any help?
Thanks for you attention.

You don't have to do anything special at all. What's in a int or a byte is what you, as a programmer, say it is. Java treats int's as signed but, in fact, with 2's complement arithmatic most operations are exactly the same. Load and store, add and subtract - it makes no difference whether a variable is signed or unsigned. It's only when you convert the number, for example to a wider type or to a string representation that you need to know the difference.
When you read an unsigned byte and you want to widen it to an integer you have to clip the top bytes of the integer e.g.
int len = input.get() & 0xff;This is because, since java sees a byte as signed it will extend the sign bit into the top bytes of the int. "& 0xff" forces them to zero.
Writing it, you don't have to do anything special at all - it will autmatically get clipped. The above is probably the only concesion you'll ever need to make to unsigned binary. (You'd need to do the same thing from unsigned int to long, but this almost never happens).
When I read ov2 files I used a mapped byte buffer, because it allows you to set either big-endian or little-endian and I wasn't sure which ov2 files used. (Sorry, I've forgotten).

Unsigned char[] problem

hi,
I am using JNI to test a C++ method that generates a random 128-byte unsigned char []. In my code, I've used a char[] to pass the unsigned char[] (as it always gives a positive number) and returned it as a jstring in Java.
However, I'm not sure in Java how I can catch the unsighed bytes using the String returned. I tried using int[] and float[] but somehow I still get negative bytes.
Could anyone pls give me some hints? any help would be greatly appreciated.
JNIEXPORT jstring JNICALL Java_RNGInvoker_getRNG(JNIEnv *env, jobject obj)
     RNG R;
     unsigned char Data[128];
     R.gen_num(Data);
     char Data2[128];
     for(int i=0;i<RNG::RNG_RANGE;i++) {
          Data2=Data[i];
     return (*env).NewStringUTF(Data2);
In Java,
class RNGInvoker {
    public native String getRNG();
    static {
        System.loadLibrary("rng");
    public static void main(String[] args) {
        String temp = new RNGInvoker().getRNG();
        byte aa[] = new byte[128];
        int bb[] = new int[128];
        aa = temp.getBytes();
        for(int i=0; i<128; i++) {
            bb[i] = Integer.parseInt(String.valueOf(aa));
System.out.println(aa[i] + ";" + bb[i]);

C/C++ uses 'bytes' for 'char'. Java uses 'chars' in Strings, not bytes. You are generating a byte array. You are then trying to return a byte array as a String. When java uses a byte array to create a String it maps it using the default language of the system. This might or might not lead to changes in actual values.
If you want to generate chars then figure out what the valid chars are for the range and language you are using.
If you want a byte array then return that not a String.

How to specify in TS unsigned long? unsigned short?

Hi,
I'm lusing a c/c++ step type from TestStand.
I need to use a structure whose fields according to the h file of the dll are:
unsigned char
unsigned long
unsigned short
Now, when I define a container in TestStand (to interface with the dll structure) my options are:
integer
unsigned integer
etc...
What am I supposed to do ? what is the appropriate numeric format?
Thanks

Hi Doug,
I'm given the dll and load of h files. The definitions you mentioned are not shown...
Suppose I want to creat in TS a container to match variable FCPortConfig. This variable structure is given here....
typedef struct tagFCPortConfig
unsigned char ucTopology;    /* For Point-To-Point use TOPOLOGY_PT_2_PT
              and for LOOP Topology use TOPOLOGY_LOOP */
unsigned char ucSpeed;     /* SPEED_1GHZ, SPEED_2GHZ       */
unsigned char ucDisableTimer;  /* (Not Currently Used) enable or disable
              timeout timer          */
unsigned long ulRRDYGap;    /* (Not Currently Used) up to a 27-bit val */
unsigned long ulRRDYGapRandomEnable;/* (Not Currently Used)enable/disable   */
unsigned long ulRRDYGapSeed;   /* (Not Currently Used) If random set;
              a 27-bit val          */
unsigned long ulRRDYGapMin;   /* (Not Currently Used) If random set;
              a 27-bit val          */
unsigned long ulRRDYGapMax;   /* (Not Currently Used) If random set;
              a 27-bit val          */
unsigned char ucAutoNegotiate;  /* (Not Currently Used) enable or disable
              auto negotiation         */
unsigned short uiBBCreditConfigRx; /* BB_credit this port will advertise   */
unsigned char ucStatsMode;   /* Determines weather or not to retrieve
                                          the extended stats counters, use
                                          STATS_MODE_NORMAL & STATS_MODE_EXTENDED */
unsigned char ucReserved[15];  /* Reserved */
} FCPortConfig;
1) Is there a way to find out how they define unsigned char, unsigned short and unsigned long?
2) Can I still use the TS default numeric type?
Thanks

Passing Jbytearray to unsigned char

Hello Group:
I am newer in JNI and I have a little problem:
I have a native method with the follow signature:
public native int enroll(byte[] template);
now I have it type data in C:
typedef unsigned char FPIMAGE; /* fp image data object */
Implementing my native method i need to call a function of a library to proccess this image(in this case the byte[]) but the signature of this method is:
FPCODE *cA = bd_fpCode(FPIMAGE *A, int xh, int yw, FPCODE buf, int qval);
A = pointer to the fingerprint image pixel matrix
xh = number of rows (height)
yw = number of columns (width)
buf = pointer to an external buffer with minimum size of FPC_MAXLEN bytes as destination for the created fingerprint code
qval = fingerprint image quality value (in %)
cA = pointer to fp-code (cA == buf) or NULL, if processing failed
There is my problem i don't now how to pass o convert my byte[] template to a object FPIMAGE.
you can help me please!

Hi,
bd_fpCode() function is a 3rd party library, right ?
You can use a JNI wapper to do that, so you do not have to write C code.
Look at http://jnative.free.fr/SPIP-v1-8-3/article.php3?id_article=4 how to pass pointers to your functions and how to handle structures.
Alternatively, you can use env->GetByteArrayElements() in your own JNI wrapper lib see (http://java.sun.com/developer/onlineTraining/Programming/JDCBook/jnistring.html).

JNI equivalent of an unsigned char *

Hi,
I have a String in Java that needs to be passed to a predefined C library routine. The routine's signature is
master(unsigned char *).
How do I pass this string so that the routine can process it.I tried passing it as a jbyte array from java , the compilation and stuff does not fail but , my routine is returning an error because it is not able to read the data.
Thanks in advance.

I'm sorry , I'm not sure if I understand this correctly,
if my method signature in my C file is
JNIEXPORT jint JNICALL Java_reflexis_bac_validation_wrapper_Validate_MY_1FPI_1Master
(JNIEnv * env, jobject methodObj, jlong instance, jbyteArray liveTemp, jbyteArray masterTemp, jobject xtraInfo){}
where I have a jbyteArray type of variable. Now I need to pass this variable to a C method whose signature is
int FPI_EXPORT FPI_Match( LPFPIINSTANCE lpInst,
                    USHORT wMatchingStrict,
                         UCHAR *lpLiveTemplate,
                         UCHAR *lpMaster,
                    LPFPI_MATCHINFO lpResults )
So are you saying I have to convert the jbyteArray to an unsigned char string . How do I do that?

Assigning a jbyteArray to an unsigned char array

I pass a jbyteArray in my method's parameter list...how do I assign it's entire contents into an unsigned char array in the body of the method?

unsigned char cbuf[...];
int cbufSize=...;
jbyteArray jbuf = ...;
jsize len = env->GetArrayLength(jbuf);
if( len>=cbufSize )
len = cbufSize-1;
if( len!=0 ) env->GetByteArrayRegion(jbuf,0,len,(jbyte*)cbuf);
cbuf[len] = '\0';

AddPreferencePanel - unsigned char*

The AddPreferencePanel function takes an unsigned char* as the menu text for the preferences dialog. I've tried storing the text as a signed char array and casting it to an unsigned char* for the function, but this doesn't seem to work. I have the following code:
char prefText[] = "Export PDF\0";
AIPreferenceItemGroupHandle prefItemGroup = NULL;
AIMenuItemHandle menuItem = NULL;
//Add the panel
sAIPreference->AddPreferencePanel(message->d.self, //Plugin Ref
reinterpret_cast<unsigned char*>(prefText), //Menu Item string
kADMNonModalDialogID, //UID of dialog in plugin resources
0, //Options
&prefItemGroup, //[out] dialog item group ref
&menuItem); //[out] menu item ref
This adds text like "xport PDF •¢£†˙gkznzºª© ag ad" to the File > Preferences menu.
Inside the Preferences dialog, the text looks like "xport PDF".
I can't figure out why the first character is getting lost. I also can't figure out why there's garbage being printed in the first instance.
Is there some special way to construct an unsigned char array? Illustrator SDK calls the argument a "localizable string". Is there some special way to construct one of those?

I am able to add a menu to the preferences panel.
But the problem is
1. If I call the sADMDialog->Modal method on click of the menu item, I am loosing the look how the preferences panel should be shown, instead the dialog comes. my intension is to display my dialog within the preferences panel as is for other prefences items.
2. If I call the sAIPreference->ShowPreferencePanel I am getting the proper preview but i am not able to edit the controls inside the dialog.
Can you help me how should I achieve both.
Below is the code I am using.
if(message->menuItem == this->PreferencesAIMenu)
//MyDialogParameters** parms_handle;
AIErr result = sADMDialog->Modal(message->d.self, "MediaBin Preferences", IDD_PREFERENCES, kADMModalDialogStyle,
// &MediaBinPlugin::InitializePreferencesDialog, (ADMUserData)parms_handle, 0);
error = sAIPreference->ShowPreferencePanel(PreferenceItemGroupHandle);
//ADMDialogRef result = sADMDialog->Create(message->d.self, "MediaBin Preferences", IDD_PREFERENCES, kADMModalDialogStyle,
//&MediaBinPlugin::InitializePreferencesDialog, (ADMUserData)parms_handle, 0);
}

How to Map in SAP ?

Hi
My client is Automobile industry.In the presales process my company delivers the goods to the dealer.On transit the goods are damaged.Instead of returning the goods the dealer him self repairs the goods and sends the credit memo to the company.The company will send the engineer for inspection and give the clearance certificate for the dealer.With reference to this we have to create the credit the customer.
How to Map it SAP....?
Plz send me the reply
Regard's
Prasad.

Dear Prasad,
As you r not taking d goodS back (or dealer is not sending them back) thus it's not a case of a Returns. Also there is no issue with d invoice either thus even Invoice Corrrection Request will not b generated.
Thus it's a simple case of creating a Credit Memo Request for the required amount i.e the amount claimed 2 b spent by d dealer. This will obviously have a block which can b removed by d engineer who went for inspection (or some1else depending on d working of d organisation). Once the billing block is removed the dealer can b issued a Credit Memo in d usual way.
Hope it answers ur query.
regards
PARAM
