How to use the nl2br() function - or addressing textarea formatting issues
the textarea does not pass line breaks to mysql - the result in the html output is one long string of text. I would like the user to input into the textarea using the enter key to create new paragraphs.
I am not a php programmer and rely on the dreamweaver data tools and developer tool kit to create my dynamic content.
Please send sample code for a form that addresses and corrects this issue. I do not know how/where to modify the code to correct this issue.
I have searched online but nowhere have I found an example of how to actually write the code. I can do a great deal of manual modification of php code but this one has me stumped for some reason..
thanks in advance !!!!
here is the index.php code which contains the form:
PHP:
<?php

How to Use the language function for assignment and validation
Hi All,
If anyone can explain me in details with example ,how to use the language function for assignments and validations?
Thanks
ArnabHi Arnab,
The expression is checked only for the current MDM session.
If u login with the ABC language it will always show the ABC language no matter how many times u execute it.
Try connecting to the DM with the XYZ language.
It should go to the if part rather than else.
Hope it helps.

How to use the CMS functionality in Sun Portal Server 7.2
Hi All,
How to use the CMS functionality using the ccd.war(Portlet) which is available in the library as i could add it to my channel but not able to show the functionality as it is showing the error msg "You are currently not logged in. Please login." should I create userid and there respective roles inorder to use the CMS functionality.
Has any one used this as I could this in glass fish server.
Any Input is appreciated.
Thanks & regards
SrikanthHave a look at the "*Roles*" section of the portal server 7.2 content management system guide
http://docs.sun.com/source/820-4275/index.html . You can also look at [project mirage|https://mirage.dev.java.net] for some screencasts
Alternatively,
1. ccd.war has 3 portlets in it:
(a) custom content definition portlet
(b) custom content portlet
(c) workflow portlet
2. Inorder to work with these portlets, user needs to be in anyone of the below roles:
(a)Consumer (b) Editor (c) Approver (d) Administrator (e) Submitter (f) Contributor (g) Publisher
3. By default ccd.war gets deployed using a default roles file (/var/opt/SUNWportal/tmp/ccd.roles.properties)
Note: In windows, you may not find this file
4. Access the portlets as a user in any of the role mentioned in the ccd.roles.properties
(OR)
you can use a new roles file which has mapping to your custom roles. For this , undeploy existing ccd.war and deploy again with a new roles.properties file
Hope this helps! -

How to use the set functions effectively in webi ,please let me know with detail
how to use the set functions effectively in webi ,please let me know with detail
Hi,
we use use set functions on heirarchies with aggregate functions mostly .
If you include member_set, Min returns the minimum value of the aggregated data for all members in the member set.
Member_set can include multiple sets separated by semicolons (;).
The list of member sets must be enclosed in {}.
If the member set expression does not specify a precise member or node, the hierarchy referenced must be present in the table, then the member set expression references the current member in the hierarchy in the table. If the hierarchy is not in the table, the function returns the message #MULTIVALUE.
Eg .
1) Ancestor
=Sum([YTD] ; {Ancestor([Test Hierarchy];2)})
2) IsLeaf
=[Test Hierarchy].IsLeaf
You can use this function when you want to show your Measure only at lower level .
3) .Depth
=[Test Hierarchy].Depth
This is also function used with hierarchy to find Level of Members .

i don't know how to use the canlendars function and the notes are kind of messy code,anyone help me
Step by step:
1. On your main vi Front Panel, create your boolean indicator.
2. On the block diagram, right click the new boolean indicator and select Create - Reference.
3. On sub-vi front panel, create boolean indicator (or use one that is already created).
4. On sub-vi front panel, create a reference (Controls Palette - Refnum - Control Refnum).
5. Right click on the newly created Refnum and select Select Vi Server Class - Generic - GObject - Control - Boolean. The refnum label changes to BoolRefnum.
6. On sub-vi block diagram, create Property Node (Functions - Application Control - Property Node). Find the BoolRefnum and move it close to the new Property Node.
7. Wire the BoolRefnum to the reference input of the property node.
8.
Right click on the property node and select Change to All Write.
9. Move mouse to point to Visible inside property node box, left click and select Value.
10. Wire the boolean indicator from step 3 to the Value input of the property node.
11. On sub-vi front panel, right click on icon and select Show Connector.
12. Click on empty connector spot then click on the new BoolRefnum. Save your sub-vi.
13. On main vi block diagram, connect refernece created in step 2 to the new connector terminal of sub-vi.
14. Save and run.
Here are the modified vi's.

How to use the Table Function defined in package in OWB?
Hi,
I defined a table function in a package. I am trying to use that in owb using Table function operator. But I came to know that, owb R1 supports only standalone table functions.
Is there any other way to use the table function defined in a package. As like we create synonyms for functions, is there any other way to do this.
I tryed to create synonyms, it is created. But it is showing compilation error. Finally I found that, we can't create synonyms for functions which are defined in packages.
Any one can explain it, how to resolve this problem.
Thank you,
Regards
Gowtham Sen.Hi Marcos,
Thank you for reply.
OWB R1 supports stand alone table functions. Here what I mean is, the table fucntion which is not inculded in any package is a stand alone table function.
for example say sample_tbl_fn is a table function. It is defined as a function.It is a stand alone function. We call this fucntion as "samp_tbl_fn()";
For exampe say sample_pkg is a package. say a function is defined in a package.
then we call that function as sample_pkg.functionname(); This is not a stand alone function.
I hope you understand it.
owb supports stand alone functions.
Here I would like to know, is there any other way to use the functions which are defined in package. While I am trying to use those functions (which are defined in package -- giving the name as packagename.functionname) it is throwing an error "Invalid object name."
Here I would like know, is there any other way to use the table functions which are defined in a package.
Thank you,
Regards,

How to use the pps function from JCOP?
Hi
I'm trying to use the pps function from JCTerminal (JCOP API: [url http://www.cs.ru.nl/~woj/jcopapi/com/ibm/jc/JCTerminal.html#pps(int, int)]pps function ) to connect my client to a virtual card with a specific protocol (T=0).
But I always got the error: "Protocol and parameter selection not supported by this terminal!"
I've tried to make an ATR that support both protocol : [url http://smartcard-atr.appspot.com/parse?ATR=3b909580811fc7dc]3B 90 95 80 81 1F C7 DC.
I really don't know what value to put in the second parameter (baud rate), I've tried with 150000, which is in the range of the ATR but I'm not sure this is correct. And I could't find any example of it.
I'm also not sure where to put the pps command, the specification say directly after a reset, so I tried this implementation:
System.out.print("Start");
readers = TerminalFactory.getDefault().terminals().list(State.CARD_PRESENT);
//If no readers has a card it ends the process
if(readers.isEmpty()){
System.out.println("\nNo card in the reader...");
return;
System.out.println("\nReader Type: "+readers.get(0).toString());
term = (PCSCJCTerminal)JCTerminal.getInstance("PCSC", readers.get(0).toString().substring(15));
term.open();
System.out.println("\nTerminal opened");
//Getting the ATR
atr = new ATR(term.waitForCard(2000));
try {
term.pps(JCTerminal.PROTOCOL_T0, (int)150000);
} catch (Exception e) {
e.printStackTrace();
System.out.println("ATR: "+toHex(atr.getBytes()));
//sending a data 11223344
System.out.println("\nsending data: 11223344");
byte[] responsesend = term.send(0,cmdsend,0,cmdsend.length);
System.out.println("Response data is:" + toHex(responsesend));
//close terminal
term.close();
System.out.println("\nTerminal closed");I've got this output on the console:
<font size="2">StartReader Type: PC/SC terminal Virtual CAD Reader 0
Terminal opened
ATR: 3b 90 95 90 00 81 1f c7 cc

<font color="red">Protocol and parameter selection not supported by this terminal!</font>

And If I take a look at the data exchanged with the card:

If someone know how to use this function or have any advice to help me to select a specific protocol with Jcop API, please let me know.
If you you need any more information don't hesitate to ask.
Best regards

I'm using a virtual terminal (windows driver), and I don't see how I could turn off the Auto-pps. I've also tried with a real reader and a card and I have the same error.
-2
I've tried value in the range of the atr (based on this analysis: [url http://smartcard-atr.appspot.com/parse?ATR=3b909580811fc7dc]http://smartcard-atr.appspot.com/parse?ATR=3b909580811fc7dc ). But I don't know if only I value of baud-rate is possible in the range. Anyway I just would like to change the protocol, not the baud-rate.
-3
I've already tried to call pps function before, after the first reset, or with another reset later and I always got the same thing.
term = (PCSCJCTerminal)JCTerminal.getInstance("PCSC", readers.get(0).toString().substring(15));
term.open();
System.out.println("\nTerminal opened");
//Getting the ATR
atr = new ATR(term.waitForCard(2000));
System.out.println("ATR: "+toHex(atr.getBytes()));
jcard = new JCard(term,atr,0);
jcard.reset();
try {
term.pps(JCTerminal.PROTOCOL_T0, (int)312500);
} catch (Exception e) {
e.printStackTrace();
}The same pps is always send after each reset... -
Hi guys,
I use the 2LIS_11_VAITM extractor to load R/3 data to BW.
On this extractor, there is an user exit which filled many fields.
I have to add the export control status of items, the value we can find in VA03 (Extras -> Export Licence -> Log -> Status green or Red).
I added a specific fields ZZEEXPCTRL (CHAR(1)) in my extraction structure as a field only know in Customer exit.
This flag will be empty if status is green or 'X' if status is red.
I'll try to use the RV_EXPORT_CONTROL function in my exit but it doesn't work.
When I execute in debug the 2LIS_11_VAITM extractor in RSA3, I can display the screen we have in VA03 (Extras -> Export Licence -> Log -> Status green or Red).
Maybe I use the bad parameters ?? But I tried many option, without result
Could you please help me and explain me how to use this function to have my result or if there is another way to do this ?
Thanks
JorisHi Namrata and Debjani,
Thank you for your suggestion. We are considering those options as well.
However, we are trying to aim for consistency between the "old" and the upgraded system. Therefore we are trying to find whether it is all possible to remove those two fields. If it is not possible at all to remove them, then we will do what you both suggested.
Best regards,

How to use the scan function on a 4215i all in one printer
How do I use the scan function on this printer with windows 8. I did the installation but the scan function does not seem to wwork
This question was solved.
View Solution.Do you have the Officejet 4215 series All-in-One printer?
If so, then there is no full feature driver for the printer. The printer is installed using the Windows Update menu of the print drivers. For information about using the Windows Update driver click here.
Do you have this printer connected via USB? If so, then there are workaround methods to get the printer to scan, as the old software package is not available on Windows 8. In the document linked above, scroll down to the section on how to scan with the Update driver to find information on how to perform these types of scans. Hope this helps.

I am confused about the import parameter 'field' and the parameter 'Container'. Can someone please suggest how to use this function?
Thanks & Regards,
Samrat DuttaHi All,
I have been able to get the value of a container element by using the macro 'swc_get_element' .I have used it in the method of my task and saved the value in a z-table. For this I have set the 'Export' property of that particular container elemnt .Now my problem is I want a second container element to be stored in the database , I have set its 'Export' property , but inspite of that it is not visible in the task container. As a result I am not able to access it from inside my method and unable to save it in the z-table. So please give me some solution.
Thanks & Regards ,
Samrat Dutta. -

How to use the same function in a column so it varies from row to row.
In a spreadsheet, I have four columns: item, quantity, price, total cost.
How can I write a function (product) for the entire "total cost" column that automatically will place the correct "total cost" for the item in that row; i.e.: =product(quantity,price)
This would save time by writing one function for the entire column so that the function would not have to be written for each row.
Thanks for your help.Question asked and responded several times.
If quantity is in column C and price in column D,
the common soluce is to use the formula:
=C2*D2 in E2
then use the fill down tool which will automatically create the formulas
=C3*D3
=C4*D4
As I am a lazy guy, I use a shorter formula:
=C*D
and fill down reproduce it as is in the other cells.
In fact I use
=ROUND(C*D,2)

How to use the CallInstrument function?
Hello!,
Related to the message "How To Use Exported Function CallInstrument of LabView.exe? <http://forums.ni.com/ni/board/message?board.id=170&message.id=118159>", can anybody show me a minimal C source example of how to generate the correct definition of the control/indicators parameters?. In other words, I need the definition of the typedef array for the datatype and the pointer to the unflat data of the controls/indicators to be passed to the CallInstrument function.
At the moment, I have just only used this función without any controls/indicadors parameters.
MgErr __cdecl CallInstrument( Path path, Bool32 modal, int32 nInputs, int32 nOutputs, ... );
MgErr MyCallInstrument( char szPath[] ) {
Path path = NULL;
MgErr err;
FTextToPath( szPath, strlen(szPath), &path );
return CallInstrument( path, TRUE, 0, 0 );
System: WinXP, LV7.1.1
Thanks !!!

Plataforma Solar de Almeria <http://www.psa.es>.Hola Javier,
Lo primero darte las gracias por contestar y lo segundo disculparme por no haberte contestado antes, pero en honor a la verdad acabo de ser padre del hijo más guapo de todo el mundo, por lo que no he podido hacerlo hasta hoy.
Pues bien, mi intención es crear un control ActiveX que pueda ser integrado en el panel frontal de un archivo VI para que pueda interactuar directamente con este mismo VI. También me gustaría que indirectamente pudiera ejecutar otros Sub-VI's, estableciento los valores de sus controles y leyendo sus indicadores.
En realidad ya expuse esto mismo en el foro
http://forums.ni.com/ni/board/message?board.id=170&message.id=150060#M150060
Pero me encontré con el problema que allí detallo, y como nadie me contestó tuve que investigar por mi cuenta llegando como último paso a la función interna CallInstrument. Y aqui estamos.
Muchas gracias de antemano.
