How to implement a Magnifier function

Could someone tell me how to implement a magnifer effect in a Java application not Java Applet.
Some example will be fine.
Thanks

If it works in an applet, it should work in an application. If there is an applet-specific method being used, many of those methods reappear in Toolkit. I think I've seen applets with source code like that at [url http://javaboutique.internet.com/]Java Boutique.

Hi Siddhehswar:
I would suggest that you use the
Ribbon. Because this is a flexible way for SharePoint. In my project experience, I always suggest my customers to use it. In the feature, if my customers have customization about permission then i can accomplish this as soon
as possible. Simple put, I utilize this perfect mechanism to resolve our complex project requirement. Maybe we customize Upload/ Edit/ Modify/ Barcode/ Send mail etc... For example:
We customize <Edit> Ribbon. As shown below.
When user click <Edit Item>, the system will
render customized pop up window.

How to implement a chat functionality?

Hi guys! I was wondering if anyone of you knows how to implement a one-on-one Chat function with servlet/JSP as the GUI and the servlet would do most of the logic processing. This servlet would know to whom the data/message is to be sent and who sent the message. I really need this. I hope someone knows. Thanks! =)

check out this link for ideas. You may even want to use the technology.

How to implement Review Page functionality

Hi,
I developed one custom Page, In that page user will enter data and click on Submit.
Requirement is before submitting, user needs review the data and click on submit.
Please suggest how to implement this functionality.
Thanks in Advance,
Hanimi.

So far I have noticed that the best idea will be to recreate and code by
myself. As You probably know each SSHR function ends with review page that shows the changes I just want the same.
So problem that I have is, I need to implement Dynamic Approvals so the
employee should be able to see who is going to approve and add approvers if
neccessary. And I cannot find any information on how to code that.
I jsut want the same functionality as in standard modules.

How XAI implements 'get more' function in CC&B pages

Hi all,
There is a 'get more' button in CC&B page if you list more than 50 records, just clicking the button when I wanna get last records , but how should i implement the same function by XAI, I have researched much time about this issue and gotten nothing. so had Anybody here encounterd the same issue? and have solved it?
any help would be appreciated.

The get more function works in the browser becuase there is a seperate "list" servlet which retrievs the data. It relies on certain HTTP context data for correct operation. Unfortunately the "get more" function is not supported by the XAI Servlet (it does not about the HTTP context data). Your only option is to roll your own paging mechnaism for the data you require.
The pattern goes likes this...
1. Work out the SQL for what you want to paginate
2. Create a new "List Service" class that will act as the underlying service
3. Annotate the service with inputs which include the page size, and the page number you want to retrieve
4. Annotate the service with a list data that will be returned
5. Use the page size and page number to create and execute the query and build the return result
6. Register the service as an XAI Inbound Service
7. Deploy the code
8. Test using Dynamic Submission
eg. Here is an example of Get More for Lookup Values....

Hi,
I can't tell. What I can tell is that the code in the sample you reference for sure doesn't cause this - but it doesn't help you I guess.
Btw.: Here is a solution that works on all browsers. The solution in the blog (Chris - please forgive me) is a bit awkward to be honest.

How to implement a callback function using LabView's Call Library Function Node?

I am trying to call a fuction from a SDK.dll library using the Call Library Function Node. The SDK was provided to
me and I do not have the source code, just the .dll and .h files.
The SdkSetPropertyEventHandler function has a callback fuction as one of its parameters. How do I implement the
callback using the CLF node? I am a good LabView programmer but this is my first time using the Call Library
Function Node. I have read all the info I can find on NI's web site and the discussion board but cannot figure
this one out. I am using LabView 8.6.
The SDK.h deacribes the function as:
// Function:   SdkSetPropertyEventHandler
SdkError SDKAPI SdkSetPropertyEventHandler(
            SdkCameraRef                    inCameraRef,
            SdkPropertyEvent                inEvnet,
            SdkPropertyEventHandler         inPropertyEventHandler,
            SdkVoid*                        inContext );
// Description:
//       Registers a callback function for receiving status
//          change notification events for property states on a camera.
// Parameters:
//       In:    inCameraRef - Designate the camera object.
//              inEvent - Designate one or all events to be supplemented.
//              inPropertyEventHandler - Designate the pointer to the callback
//                      function for receiving property-related camera events.
//              inContext - Designate application information to be passed by
//                      means of the callback function. Any data needed for
//                      your application can be passed.
//      Out:    None
// Returns:    Any of the sdk errors.
A separate header file called SDKTypes.h contains the following data:
typedef SdkUInt32 SdkPropertyEvent;
typedef SdkUInt32 SdkPropertyID;
typedef void       SdkVoid;
typedef struct __SdkObject*    SdkBaseRef;
typedef SdkBaseRef    SdkCameraRef;
SdkPropertyEventHandler
typedef SdkError ( SDKCALLBACK *SdkPropertyEventHandler )(
                    SdkPropertyEvent        inEvent,
                    SdkPropertyID           inPropertyID,
                    SdkUInt32               inParam,
                    SdkVoid *               inContext );

Basically you do not do that. LabVIEW does not know pointers and certainly not function pointers. What you should do instead is writing a C DLL that implements the callback and also exports a function to be called by LabVIEW that translates between the callback and a LabVIEW user event. Look for PostLVUserEvent() here on the NI site to find examples how to do that.

How to Implement the same functionality of IT1610 and IT1641 for CANADA

Hi experts,
We have done HCM Implementation to US and now moving to CANADA. We got the requirement to create two custom OM infotypes which are similar of IT1610 and IT1641 in US specific. But when I check the functionality of IT1610, it is maitaining by calling a view T5U13. It looks like some complex logic is there behind the screen. I am able to create basic custom infotype but not able to implement the logic to calla a view (T5K13 in CANADA) through PP01 or PO03 and then maintain the view as well as the infotype. How the view screen is embeded in creation of IT1610 screens.
Could you please help me on providing the solution for this?
Thanks for your time and waitaing for your valuable reply.

Hi Idrees,
You need two grids and at least 3 datatable.
Grid 1 bound to DataTable 1 - This will list all the Items, nothing special about this one.
Grid 2 bound to DataTable 2 - This will list selected batch for current selected Item in Grid 1.
DataTable3 - This will hold all the selected batches for all the items in Grid 1.
Now you need to refresh DataTable 2 based on the Selected item in DataTable 1.
When the user click on a row in DataTable 1, you need to do 2 things :
1. Read all the records of DataTable 2 and sync it to DataTable 3.
2. Read all the records of DataTable 3 where the Item Code belongs to the Item selected in Grid 1 populate it into DataTable2.
Tedious, but will do the job.
When the user click Add/Update button, write the records of DataTable1 and DataTable3 into database.

How to implement the Transfer Function in Real Time VIs?

Hi all,
I'm relatively new to Labview Real Time modoule and want to implement one Controller(not PID one) in Deterministic Loop! I have already designed discrete Transfer Function and searching for the way to build one Controller with it! Is it right to use the Simulation Loop instead of Timed Loop (in this case Deterministic loop) and implement the controller in it?! If it's correct so, should I use the same clock and Priod as Timed Loop?!
It would be very helpful, if there is an Example about using transfer function in Real Time Loops!
thanks for your help,
Mohsen

Hello mhmdi,
Sorry I can't open your VI (looks like it is a new version of LV than I have installed).
You're right - you don't need to convert to a difference equation if you have the CD&SIM Module which can take discrete time transfer functions directly. You don't need shift registers with this function, as it is effectively done internally. If you don't have CD&SIM discrete TF's can be implemented easily just in a timed (or while) loop with feedback nodes or shift registers to replicate each z-1 you need.
Some more ideas:
There are many configuration parameters and options with the Discrete TF VI - which you need to understand for your application and make sure are correct. Sometimes implementing in a basic form (timed loop and shift registers) allows you to see what is happening without any confusing options you might not need.
Are you using the Discrete TF VI in a Simulation Loop ? You might need to think if the loop being used is appropriate for a Real Time application. Maybe the timing of the TF, the loop and the DAQmx data are not all suitable for each other.
I'm not familar with DAQmx, so not sure about any specific real-time aspetcs of that.
"if the sample frequency of the discrete transfer function in the timed-loop is at multiple integers of the sampling rate (e.g. 12000 Hz for tranfer function and 4000 Hz for sampling rate, 12000=3*4000), would it somehow improve the resolution of the controller command?"
This could actually make things worse - but depends on your transfer function if it is a problem. Think about it this way - in the scenario you state the input signal going into the Discrete TF will only change once in every three samples, that means if your transfer function includes a 1-z^(-1) factor (i.e. a derivative) - that will be zero for two samples then jump up for the next sample. You'll observe a very jittery/noisy signal, but the noise is due to samples not being correct. This will also occur if the sample times are very similar but go in and out of sync where you may get the occassional sample that is the same and hence the occassional zero in the TF.
In an application I had we had problems trying to get the data coming into a timed loop and the timed loop itself synchronise, and before it was fixed the control signal was very jittery.

How to implement this planning function using Fox formula

Hello,
I am new to Fox.
I want to implement this complex logic in a planning function
i have A (Kf X from infoprovider Z_A), B (Kf Y from infoprovider Z_B) & moreover there is one more condition,
If current FISCPER > variable value of FISCPER
KF Z = KF Z1 (from Cube C1)
Else KF Z = KF Z2 (from Cube C2).
for a particular calender week,
X = ( Y * Z ) / (summation of (Y * Z) for each week of the whole year)
I know it is complex.
but i have to implement this in a planning function.
The aggreagtion level is built on a multiprovider having A, B , C1 & C2.
Can someone help me out with the FOX formula for this? or is there any better way to do this.
