Problem with call of function F4UT_RESULTS_MAP in search help exit

Hi everybody,
i have a problem concerning call of function F4UT_RESULTS_MAP.
I call this function in this way:
CALL FUNCTION 'F4UT_RESULTS_MAP'
       TABLES
            shlp_tab          = p_shlp_tab
            record_tab        = p_record_tab
            source_tab        = lt_zv055[]
       CHANGING
            shlp              = p_shlp
            callcontrol       = p_callcontrol
       EXCEPTIONS
            illegal_structure = 1
            OTHERS            = 2.
in lt_zv055[] there are results from previous select, but i want to select only values,
that match select options that are specified in p_shlp.
But it always shows all the values that are in lt_zv055.
What am i doing wrong?
Thanks in advance.

Read the "Notes" part in FM documentation and you will find the reason .

How jsp can call applet functions

good morning to all java experts
i have one problem that is
in my application i have one applet in the server side which contains functions like encryption, decryption, hash functions.
whenever any client wants to store some information on server side then he download the applet from the server and he gives his own key and encrypt all the contents and these encrypted message only transmitted through media and store on server side
whenever clients wants to retrieve some information from server then he fetch the only encrypted message to client side then he down load the applet from server and decrypts the message as he pass the previous key.
the problem is that whenever jsp calls the applet functions through javascript it displaying error message like: error in the jsp page
but this concept working through html page properly
plss reply as soon as possible
thanking uuu

the problem is that whenever jsp calls the applet functions through javascript Show the relevant code how you thought to accomplish this (this is namely impossible without firing a new request to the server).
it displaying error message like: error in the jsp pageAnd further on, you -as developer- should know that it is not-done and unclear to talk about errors if they are irrelevant. Always post and the full, complete, original and unchanged error message and -if in Java- also the stacktrace. They are helpful in debugging.

Linux: JS cannot call Applet functions

I was wondering if anyone else has had this problem:
Our platform is RedHat Linux 7.2 with Mozilla 0.9.7 and 0.9.8 as well as NS 6.2.1 (I have tried JRE 1.3.1_01 and 1.4 rc1)
Whenever I load our applet in a frame and try to call the applet functions I get a JS error stating "Applet.xxx() is not a valid function"
Loading the same applet in a standard page (no frames) works fine. Also the framed applet works fine on the windows platform.
I'm guessing this is more of a Mozilla/NS problem that a Java problem, but I have foudn little information elsewhere and this forum seems to be filled with lots of great info.
I have submited this as a Mozilla bug:
http://bugzilla.mozilla.org/show_bug.cgi?id=121641
The URL has case code examples.
Thanks, Jesse

If your applet requires a Java plugin, you have to realize that Netscape's LiveConnect has not been fully ported to JRE1.4 rc1 and neither Mozilla nor NN6.2.1 has its own JVM. Altho I have NN6.2, I seldom use it because it's still very buggy and extremely slow.

It seems to be compiled for WinCE. Assumed that you have Win2000/XP/Vista/7. Check your MSVC build settings.

when i am trying to run the SQL statement it is returning a exception from the function.

My sql client version is 9.2.0.1.0. and my data base version is 10.2.0.2.0.
Please advice.

Could you post the exception handler within the function.
It sounds like you return -1 if you experience an error - it would be easier to determine the cause of the problem if you return the Oracle error details, E.g:
EXCEPTION
WHEN OTHERS THEN
RETURN dbms_utility.format_error_backtrace;This will then return a meaningful error, identifying exactly what is causing the error to be generated.

Strange problem of calling library function node in labview 2010 and 2011

one year ago,I develop a program to usb device data and it works well,in labview 8.6 or 2009(win xp).Recently, When I test
the program in labview 2010 and labview 2011(win xp).,the program always crash immediately.I check the program and find main
problem is in call library function node. In my program,I use labview 2009 library for the USBExpress driver for
Silicon Labs USB MCU's from:https://decibel.ni.com/content/docs/DOC-9522,for example, 2 functions SI_OPEN and SI_READ
can not work well.
the header definition of SI_OPEN and SI_READ is:
SI_STATUS WINAPI SI_Open(
DWORD dwDevice,
HANDLE* cyHandle
SI_STATUS WINAPI SI_Read(
HANDLE cyHandle,
LPVOID lpBuffer,
DWORD dwBytesToRead,
LPDWORD lpdwBytesReturned,
OVERLAPPED* o = NULL
the SI_STATUS is equivalent to int type.
orignally, for HANDLE * in SI_Open, the parameter type in call library function node is numeric, data format is unsigned 32 bit integer ,and pass pointer to value.
for HANDLE in SI_Read, the parameter type in call library function node is numeric, data format is unsigned 32 bit integer ,and pass value.The program works well in labview 8.6&2009,however,crash in labview 2010 &2011.
later,I debug the program, for HANDLE *, I choose parameter type in call library function node as adapt to type, data format is point to Handles.for HANDLE, I choose parameter type in call library function node as adapt to type, data format is Handles by Value.Crash not happend in labview 2010&2011,however,it cannot read any data from from USB device correctly as before.I can not find the reason.
Dear friends,I need your help to answer the problem. Thank you.

Based on the help page it looks like it should execute asynchronously.
The thing in the description that leads me to believe they execute asynchronously is that you can configure the library to run as a multi-threaded operation.
Please take a look here to see the difference between synchronous and asynchronous execution.
Since the code even has the ability to be multi-threaded, you can consider it as running in parallel to your other code.
Any data returned is passed to the thread that called that function.

Problem in calling AVM1Movie function

Hello all,
I have loaded an Action Script 2.0 swf file in Action Script 3.0 file. I want to call a function of Action Script 2.0 function from Action Script 3.0 file.
following is the code i am using.
Action Script 3.0:
var loader:Loader=new Loader();
loader.load(new URLRequest("2.swf"));
addChild(loader);
loader.contentLoaderInfo.addEventListener(Event.INIT,swfloaded);
var banerObject;
function swfloaded(e:Event) {
banerObject=Object(loader.content);
btn.addEventListener(MouseEvent.CLICK,clicked);
function clicked(e:Event){
banerObject.as2function();
Action Script 2.0:
function as2function(){
trace("function is called");
Please let me know, how i can call that function.

I believe you need to make use of LocalConnection to communicate between different version files. While I am fairly well confused with it, the following may be helpful for you.

Problem with Call Library Function. Want to pass a string and return a string, but my compiler does not recognize "CStr" and Labview does not recognize my "char *function()" callout

Hi, I'm trying to use a .DLL I wrote in Visual C++ .NET. The Call Library Function generates a function prototype of "CStr Parser(CStr arg_raw)"
but my compiler won't accept this. So I change it to how C normally deals with strings "char *Parser(char *arg_raw). Now the Call Librafy Function does not find "Parser" in my .DLL though it is definitely there!
Help!
-Fong

Hello
You will need to include extcode.h in your C file. You can find this under ..\LabVIEW\cintools folder.
The include has all the defines you will need.

Problem with calling a function through onclick event in a tag

Hi All,
I have a text which should act as a link.
On click of this text i need to display the table in the same page.
this is how i want to do
!<_ a     !st y l e='cursor pointer' h_ r ef =' #' !o n cl ick = " l o a dtc () " _> display table _< / _a _ >
!<   % if i_ref = ' X' % _>

!< s_c rip t t y p e =   "te xt/ja v a s c r ipt" >
!f unct io n lo a dt c ()
i_ref='X'.
!< _/ s c r i pt _>
here am setting a flag and if that flag is set i will display the table.
Please ignore the unewanted characters in my code. i was not able to paste the code directly.
Thanks,
Sandeep
Edited by: SandeepReddy on May 25, 2010 9:22 AM

Hi Sandeep,
are you using javascript to get the link in the text view?
i will tell u onething clearly.
if you are using javascript in ur code, debugging will not wrk properly , what you need to do is add the alert in between so that you can know whether that particular code is wrking or not ok.
2) to call the javascript from the textview or the inputfield you have a attribute called onClientClick you need to call the function there and implement that function in javascript.
<htmlb:textView text   = "<%= i_str %>"
                        design = "EMPHASIZED"
                        onClientClick = loadtc() />
add ur javascript code ok
cheers

Problem with calling a function within a function

My problem is with the getWidth and getLength functions. The problem I am having is with the fact that when I get an incorrect input I pass it through the function again, which give me a weird return. The return I get is the correct input plus all the previous incorrect inputs after that. The one that gets returned is first incorrect input? I don't know if you understand, but I would appreciate help for this beginner.
**Sorry about posting in this forum... I just realized this is not for beginners. Help would still be appreciated.**

You're calling things recursively and that's not good (at least not here).
To clarify, please look:
    public static double getLength() {
        if (something) {
            do something else
        else {
            System.out.println("Incorrect input!");
            getLength(); // you call the entire method again here! This is the recursive call
    }Better is to have a while loop inside the method and repeat this loop until the input that the user enters is correct (or until they quits).
