How to use the class CL_PT_EMPLOYEE with GET PERNR?

Hi,
I saw this sample code on the forum.
Is it more performant than using the "RP-PROVIDE-..." macros?
Does the employee instance needs to be killed after each pass? How does it affects memory?
start-of-selection.
GET pernr.
<b>* Create employee instance</b>
gif_employee = cl_pt_employee=>get_employee( pernr ).
go_employee ?= gif_employee.
<b>* Append all other required infotypes to itab</b>
APPEND '0003' TO gt_infotypes.
CALL METHOD go_employee->get_infotypes
    EXPORTING
      i_itlist      = gt_infotypes
      i_fromdate    = id_fromdate " start date
      i_todate      = id_todate    " end date
*      I_FILTER      =
      i_noauthcheck = 'X'
    IMPORTING
      e_result      = gt_infty_request
      e_retcd       = gd_retcd.

I think it that way. You are trying to compare and analyse old (don't say bad) programming school with a new (OO one) approach. Although, I am OO enthusiast and in any case I will try to convice you that OO aproach is better than classical one, you should know what SE30 was designed for. If you want to stress on OO design, use the one you mentioned, otherwise stick what SAP recommmends (please note, that I am "middle" school pupil, so I tried to learn all courses with my own experience and feelings from OO).
IMHO, OO aproach is a way of thinking, not something we can messure in sec. and compare to old school teaching. Some of your report should be desinged in classical way, some should be pure OO. Which one you choose, is up to you, your conclusions, your percives of ABAP language. For me OO was not injected in ABAP enough, to affect developers or to convince them using it in any case w/o doubts you have.

How to use the class CL_CTMENU with the method DISABLE_FUNCTIONS

Hi Friends,
How to de-activate some functions in the Menu bar?
Eg: - Sales document
             Create
             Change
             Display
I want to de-activate "Change"
In other words: - How to use the class CL_CTMENU with the method DISABLE_FUNCTIONS in my program.
Regards,
Hari

Krishna,
It is not possible to deactivate the CHANGE option in themenu bar using the method disable_functions of cass CL_CTMENU. This method allows you to deactivate only the function codes of the CONTEXT MENU, which is available only when u press the left mouse button.
U can use the SET PF-STATUS 'XXX' EXCLUDING fcodes option to disable the CHANGE.

UIX/JSP - How to use the UIX Controller with UIX/JSP

After reading the UIX Developers Guide I am under the impression that I could use the UIX Controller with UIX/JSP pages. Is this correct and are there any available examples?
Bill G...

It's correct, but I'm afraid we don't have much (read as "any")
documentation on how to do that - besides reading through the
gobs of Javadoc and guessing how to put it together.
Half of the problem is solved by registering JspPageDescriptions
on a PageBroker (e.g., UIXPageBroker) to tell the UIX Controller
to use a JSP to render a particular page, instead of a UIX XML
document.
The other half is getting the JSP to send requests back to
the UIX Controller. Depending on how you've chosen to name
your pages, create either a DefaultPageEncoder or ExtensionPageEncoder
inside your JSP, and use that to create destination URLs.

How to use the crypto api with gemalto cyberflex 32k ?

Hello ,
I've done many javacard programs using this method :
_compilation with javacard kit 2.2.1
_convertion into ".cap" with the javacard kit 2.1.2
All this programs work fine with this method : helloworld, read, write in the card, ....
But when i want to use the crypto api, i can't charge the program in the card (just by adding 2 lines for generating keys):
----------> returns 0x80206A80 (6A80: Wrong data / Incorrect values i data.)
I think it's because i use the 2.1.2 version , but if i use the 2.2.1 to convert , it's another error and no program work with this method.....even helloworld doesn't work...
-----------> returns 0x80206985 (6985: Command not allowed - Conditions of use not satisfied.)
I thing i must change my gpshel command , but i have read many forums but can't find the configuration for my card cyberflex 32k, some people had similar problems so they used the kit 2.1.2 combined with 2.2.1 like me, but i think they can't use the crypto api with this.........
Any help will be apreciated,
kind regards

How to use the JE database with other data types than byte arrays?

Hi! I searched the javadoc of Berkley DB JE, for a way to introduce entry (but I need also retrieve) data with other type than byte arrays, e.g. String, or anything else, as int may be, etc.
Still, I didn't find any such way, because the main (only?!) method to entry data into an open database - according what I found in javadoc - is:
"public OperationStatus put(Transaction txn, DatabaseEntry key, DatabaseEntry data) throws DatabaseException"
and both this and the corresponding method for retrieves, are based on the same DatabaseEntry type, which allow only entry data on byte[] support.
What if I need to use Strings or int, or even char? I must do a special conversion from these types, to byte[], to use the database?
Thank you!

How to use the pid vis with a two-state output

Hello
Could someone tell me how to regulate the temperature of a room with
a two-state heater (on/off), using the pid vi's.
Thanks,

^^^^^^ ^^^^^^^ ^^^^^^^
Frankly, I tend to agree. However, if you _need_ PID control and _if_
your two-state heater is solid-state switched, there are other
options. For example, commerical PID temperature controllers with
zero-voltage switching (ZVS) operate by generating a slow enabling
pulse, then achieving proportional control by varying the duty cycle of
this enabling pulse. For instanance, if your enabling pulse is running
at 10-Hz, with 50% duty cycle,
then your heating element will be on for
50% of the time every 0.1 second.
You can use a programmable timer (National includes two on their MIO
cards) to program the 5 or 10 Hz output and its duty cycle. You might
have LabView execute the PID subVI once every two or three seconds to
adjust the duty cycle on the programmable timer so as to minimize the
feedback error=(tempSetPoint-currentTemp).
Why are you wanting to use LabView for PID temperature control in the
first place? There are some very good PID temperature controllers
(programmable through a serial port) with built-in solid-state ZVSs
and readouts for $900 that you can buy. They'll fit right into
a control panel, display and all. Sure beats messing with a
programmable timer card and its outputs, plus you get a digital panel
readout to boot.

How to use the sharing function with other pc on the Finder sidebar?

I discver my housemates' pc's names under "sharing" on the Finder sidebar. We all use the same wifi network at home. Neither they nor I have enabled anything so I'm just wondering what is that for and where am I able to control sharing options?
Also I can even access their iTunes libraries. How do these all work? Am I able to set any security options at all?

How to use the html:link with a arraylist

Hi everyone:
I want to display the data using struts html:link.
I query the database and place all the data to javabean,later place all the javabean to ArrayList.In Action,I use the "request.setAttribute("lovetable",articlelist) to set request to jsp page.
I want to pass a parameter "id" use the hyperlink so I can get the parameter when I click the hyperlink.
But how to use html:link to display it?
I use <html:link action="viewtopic.do" paramId="id" paramName="lovetable" paramProperty="id"/>,it can't work and Tomcat report error :
org.apache.jasper.JasperException: No getter method for property id of bean lovetable
     at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:248)
     at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:295)
     at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241)
The lovetable is a ArrayList and it don't have a getter or setter method.
How to use it pass parameter? :( Thks

Thank you.
I use the bean:define successful.And display all the data to jsp.My jsp code is:
<logic:iterate id="love" name="lovetable">
<bean:define id="idbean" name="love"/>
<tr bgcolor="<%=color%>">
<td><bean:write name="love" property="id"/></td>
<td><html:link forward="viewtopic" paramId="id" paramName="idbean" paramProperty="id"><bean:write name="love" property="title"/></html:link></td>
<td><bean:write name="love" property="name"/></td>
<td><bean:write name="love" property="time"/></td>
</tr>
</logic:iterate>
In Action : request.setAttribute("lovetable",articlelist)
ResutlSet rs=.............
List articlelist=new ArrayList();
while(rs.next()){
articlebean bean=new articlebean();
bean.setName(rs.getString("name"));
bean.setTitle(rs.getString("title"));
articlelist.add(bean);
The above code will work property.
The Tag "html:link" need bean to work other than arraylist so I iterate all the bean out.
The Tag "logic:iterate" need collection to work so I make Action return a List.
right?
Any idea? :)

How to use the Rc4DLL.dll with java (jre1.4 )

I am not able to use Rc4DLL.dll with java, there are some characters (encrypted using Rc4DLL.dll) that java is not able to identify. So while decrypting in java using Rc4DLL I am not getting the desired output (as some character java tries to decrypt are not supported with java). Could some one give a solution of using Rc4DLL with java jre 1.4

RC4 cipher is supported by 1.4.
And surely you can turn a link to the 1.5.0 JCE Reference Guide into a link to the 1.4.2 Reference Guide? I did. Took me 5 seconds to check that. As opposed to wasting a day and a half in forums like you just did.

Don't know how to use the air print with my ipads.

i just bought an mg3222 printer and i don't know how to figure out how to use air print with my ipad and ipad minis. Can anybody help??? Thanks

Hello.
In order to use the printer with your iOS devices, please make sure that the units are all connected to the same WI-Fi router. Once this has been done you should be able to print.
The initial Wi-Fi setup of the MG3222 would have to be done from a compatible Windows or Mac OSX computer.
If additional assistance is needed, feel free to call us at 1-800-OKCANON.

How to use the CJC channel with 9211 in labview?

Hello there,
I have cDAQ-9172 with the 9211 module for some thermocouple measures.
I want to use 1 channel for the CJC and the others for normal teperature measurements.
I have the VI attached.
Thanks,
Sandro

Hi Sandro,
By "I want to use 1 channel for the CJC", are you talking about using the NI 9211's built-in CJC channel, _cjtemp?
If so, go back to the original example code and set the CJC Source control to Built-In. This will cause DAQmx to use _cjtemp as the CJC source. You won't see the CJC temperature on the graph by default: Reading the CJC Values with the Thermocouple Measurements.
If you have an external CJC sensor connected to one of the thermocouple channels (ai0:3), then create a global channel in MAX (thermistor, or voltage w/custom scale), specify the name of that channel in the CJC Channel control, and set CJC Source to Channel. It's better to use the built-in CJC sensor unless the external CJC sensor is definitely more accurate, and not less.
Regarding the Start button you added to the example VI, I would recommend moving the call to DAQmx Create Channel out of the polling loop so that it doesn't leak memory by creating DAQmx tasks that never get used. Adding a call to Wait Until Next ms Multiple (from the Timing palette) or Wait For Front Panel Activity (from the Dialog & User Interface palette) would prevent the polling loop from wasting CPU cycles.
