Remove a Function from SAP.Functions (opposite of .add)
Hi,
I have a function written in SAP which I call several times with new importparameters (called by VBA/Excel). The output goes to a table.
Although the functions clears the table, the table just keeps growing in the result.
It seems like the data is kept, but I guess with every new call all the previous functions get called as well, so I need to unload the function every time (un-add it ), however I don't know how to do this (I didn't try obvious commands like REMOVE or so, as I guess it might reset also the connection).
Can anyone help me with this ?
Thanks,
Alain
In addition, some snippits:
Set functionCtrl = CreateObject("SAP.Functions")
Set sapConnection = functionCtrl.Connection
(than login is done)
The above is called only once, the next part several times with new matererialnumbers....
Set theFunc = functionCtrl.Add("YRFC_MyFunc")
theFunc.exports("Mat") = MatNr
FuncResult = theFunc.Call
If FuncResult = True Then
For Each veld In theFunc.tables("TABUIT").Rows
Cells(teller, 6) = veld("MFRNR")
Cells(teller, 7) = veld("LIFNAME")
Cells(teller, 8) = veld("HTNNR")
Cells(teller, 9) = veld("MFRPN")
Cells(teller, 10) = veld("MSTAE")
teller = teller + 1
Next
Set theFunc = Nothing
Else
Cells(teller, 6) = "???"
End If
If I clear the table with 'free' i.s.o. 'clear', the problem doens't occur...(I had to change something else when I remembered that clear isn't always the best for Tables)
However, now just for fun, if any knows if a function can be removed, please reply anyway

Removing a User From SAP and Webtools
I have recently removed a user from SAP which was a user from webtools
i removed their license and removed them from webtools
My issue is that i now have a Sync Error
-10:Selected user was deleted
at NetPoint.SynchSBO.WebToolsChildObjects.AccountUser.SynchOUSR(NPUser u)
at NetPoint.SynchSBO.WebToolsChildObjects.AccountUser.NetPointToSBO(NPQueueObject qData)
at NetPoint.SynchSBO.SynchObjectBase.Synch()
What can i do to remove this error?
Please notify.
all answers and suggestions will be greatly appreciatedUser probably still exists in WebTools. Try to find & remove it.
If this doesn't help, you can remove user from synchronization queue:
1. run SynchManager
2. on page Synchronization click on tab Web tools Queue
3. find row with 'Name' equal NPUser; click on number in column 'Fail'
4. select row containing error message
5. press <Delete>
6. run synchronization -
If you remove a backup from Time Machine, can you add it later?
if you remove a backup from Time Machine, can you add it back later? I have two backup sets active, but only one is connecting to a drive at the moment. It seems to be pausing TM for the inactive one, which is as I would expect, except that the menu icon for TM shows an exclamation point (= "waiting to backup"). I'd rather have that error / pause sign show if the ACTIVE connected drive is experiencing issues. It has zero diagnostic function as currently set up.
The solution would be to remove the backup drive from the TM list and then add it back later. I am just unsure if I can do this (will TM recognize the alternate backup set again if I re-add it?)
txYes, you can re-add it.

Calling a Function from another Function within CFC
Hi all,
I have many functions in my CFC that do various things, but
one query is a query that selects absolutely every record from a
table.
The thing is, I need to do a query like this in another
function to obtain only a recordcount of the same table used in
both separate functions. Instead of writing the query out again,
how can I utilise the function already written?
My question is, how can I invoke and use the results of a
query in one cffunction for another cffunction in the same CFC
component?
An example may look like the code attached...
Many thanks for your patience and help!

Generally, to call a function from within a cfc, you do
exactly what you do outside a cfc.
For your specific case, if your requirements permit it, you
might consider caching the big query for a couple of seconds. Then
you can continously call the function and not have to wait for it
to run and bring back the data each time.
Do you mean to say that within a CFC function I can execute
the same cfinvoke tags I use in normal CFM pages?

How do i call a Function from another Function ?
When i press a button, i want a series of functions to execute one after another (they contain tweens, but its irrelevant), each of them waiting for the previous to be completed. I want to put the series of functions inside one function, so i can call just this function to execute all the others. The animations are working fine, but i dont know how call Functions from within another function. Also it would be necessary each function to wait until the previous has completed, to execute. Here is a clear example of what i need to do:
boton.onPress = animate ;
Function animate () {
animation1 (onComplete: animation2);
animation2 (onComplete: animation3);
animation3 ;
Function animation1 () { Tween 1};
Function animation2 () { Tween 2};
Function animation3 () { Tween 3};
any suggestions ?I'd do something like this:
boton.onPress = animation1 ;
Function animation1 () {
var Tween1 = new Tween();
Tween1.onComplete = animation2;
Function animation2 () {
var Tween2 = new Tween();
Tween2.onComplete = animation3;
Function animation3 () {
var Tween3 = new Tween(); -
How to call C functions from native functions?

i wrote somthin like this:

#include "testPhase1.h"
JNIEXPORT void JNICALL

testPhase1(threshSim, threshSup, itemSim);
return;
And I always get "undefined symbol: testPhase1__Fddd" error!
what is the problem here? thanks alot!
JimBasically - you are already are compiling a c file. Replace that c file with all the c files.
Specifically it depends on the OS, compiler and how you are compiling
For windows add it the project or compile each file and then add the object fill to the link line.
For unix add the other c files in to the compile line the same place you have the current C file. -

Problems calling a function from another function
Hello all.
I am trying to create a function that will loop a few other function.

nsPublish = new NetStream(nc);
nsPublish.addEventListener(NetStatusEvent.NET_STATUS, nsPublishOnStatus);

// add custom metadata to the stream
var metaData:Object = new Object();
metaData["description"] = "Chat using VideoChat example."
nsPublish.send("@setDataFrame", "onMetaData", metaData);
// attach the camera and microphone to the server
nsPublish.attachCamera(camera);
nsPublish.attachAudio(microphone);
doPublish.label = 'Stop';
else
// here we are shutting down the connection to the server
nsPublish.attachCamera(null);
nsPublish.attachAudio(null);
nsPublish.publish("null");
nsPublish.close();
doPublish.label = 'Publish';
I am then trying to call that function like this
protected function startloop():void {
publish(event);
But i get the error Access of undefined property event.
Any ideas on how i can call this function ? I need to call it as part of a loop against a timer..
Thanks in advanceNeed more info. Are you using a ViewStack or other navigator container, and trying to access a view that has not been displayed yet, due to deferred instantiation?

Calling an OA Function from another function
Hi,
I need to create a link in a function that calls another function.
I've created a new Item 'Static Styled Text' writing in the destination URL 'OA.jsp?OAFunc=FUNCTION_NAME&pPersonID=&pFromMenu=Y'.
I am able to connect to the Function but the person_id parameter passed is not the right one.
To be clear I'll write down an example. I am a super user and in FUNCTION A I query an employee and enter in the function. Subsequently I click on the link I've created to view this employees information in FUNCTION B. Instead it queries my information, passing my person_id.
Can someone help?
thanksYou would need to get hold of the person id of the employee you queried, this may be a VO attribute
Once you get the person Id, you would need to set the URLs parameter value to this value.
so the URL when you are in the next pahe would look like
http://<server:port>/../OA.jsp?OAFunc=FUNCTION_NAME&pPersonID=<the value you passed>&pFromMenu=Y
Thanks

Calling another function from run function
Dear All,
Below is my skeleton of multithread programme. I am now going to implelment a new function to do the processing rather then over crowding my run fuctnion. Where exactly must I define the myNewFunction in the same class as ConnectionHandler or create a new class? What would be right? I saw some place you need to put the word static what is it?
class ConnectionHandler implements Runnable {
public void run() {
callMyNewFunction()
}Dear Jverd,
Basically below is code skeleton. So below the big T is new Thread(new ConnectionHandler(socketConn1)).start(); correct and the small t is the run function correct? So my question is that if via the run function I call some other function will that have impact on the memory allocation or shall I leave all my codes in the run function itself? I hope I am clearer now.
public class commServer {
public static void main(String[] args) {
try {
final ServerSocket serverSocketConn = new ServerSocket(9000);
while (true)
try
Socket socketConn1 = serverSocketConn.accept();
new Thread(new ConnectionHandler(socketConn1)).start();
catch(Exception e)
System.out.println("MyError:Socket Accepting has been caught in main loop."+e.toString());
e.printStackTrace(System.out);
catch (Exception e)
System.out.println("MyError:Socket Conn has been caught in main loop."+e.toString());
e.printStackTrace(System.out);
//System.exit(0);
class ConnectionHandler implements Runnable {
private Socket receivedSocketConn1;
ConnectionHandler(Socket receivedSocketConn1) {
this.receivedSocketConn1=receivedSocketConn1;
//@Override
public void run() {
Connection dbconn = null;
BufferedWriter w = null;
BufferedReader r = null;
try {
PrintStream out = System.out;
BufferedWriter fout = null;
w = new BufferedWriter(new OutputStreamWriter(receivedSocketConn1.getOutputStream()));
r = new BufferedReader(new InputStreamReader(receivedSocketConn1.getInputStream()));
int m = 0, count=0;
String line="";
String n="";
//w.write("$PA\n");
//w.flush();
while ((m=r.read()) != -1)
///**DB processing here.
n="";
catch (IOException ex)
System.out.println("MyError:IOException has been caught in in the main first try");
ex.printStackTrace(System.out);
finally
try
if ( w != null )
w.close();
else
System.out.println("MyError:w is null in finally close");
catch(IOException ex){
System.out.println("MyError:IOException has been caught in w in finally close");
ex.printStackTrace(System.out);

Calling function from inside function using powershell
In my powershell script, I am using following code, first time it will go in another function and returns back original function, but in next time in loop, it open popup "Process [0]" and asking for input. I want my second function runs for each
site collection. Let me know what I am missing.
function test {
# Get site objects
$site = Get-SPWeb "http://l-1562571"
write-host $site.Url
#Call Function
$admin = AddLevel123($site.Url)
# Walk through each site in the site collection
$site.Url | Get-SPWeb -Limit all | ForEach-Object
$admin = AddLevel($site.Url)
function AddLevel($site)
param([uri]$site)
$web = get-spweb $site
#Dispos off web/site object.
if ($web -ne $null)
$web.Dispose()First thing It seems you there is typo in method name. Anyway better should use like this. It is more easy and straight forward. Hope this helps you
# Get site objects
$webapplication = Get-SPWebApplication "http://l-1562571"
# Walk through each site in the site collection
foreach($site in $webapplication.Sites)
foreach($subWeb in $site.AllWebs)
$_ = AddLevel123($subWeb.Url)
