How can I implement operator overloading in order to concatenate 2 Lists ??

I figure that this question is very didactic, for users unfamiliar with Operator Overloading.
My application needs to perform 2 different searches and the results are stored in a List<string>.
List<string> myList1 = PerformSearchStrategy1();
List<string> myList2 = PerformSearchStrategy2();
Next, I need to concatenate the 2 Lists.
I figured that a very elegant way to code this would be as follows:
List<string> myOnlyList = PerformSearchStrategy1();
myOnlyList += PerformSearchStrategy2();
myOnlyList += PerformSearchStrategy3();
The problem being that I am barely familiar with operator overloading in C#.
Can a kind soul please illuminate me and other readers?
TIA

You should not use operator overloading for this for a couple of reasons. But the simplest is that you don't own List<T>, and so can't add operators to it.
Instead just call AddRange()
List<t>.AddRange Method </t>

How can i implement 'Distribute Qty' function in BAPI_GOODSMVT_CREATE

Hi all,
Using MIGO For GR. if more than one Batch or Production Date or Vendor Batch for same Purchase Order Line Item and Deliv date, need to hit Distribute Qty button to split the entry line into multiple lines before enter Production Date and Vendor Batch.
So I want use bapi BAPI_GOODSMVT_CREATE implement MIGO function for a interface. Anyone have some suggestion how can i implement the 'Distribute Qty' function in the bapi.
My email address: [email protected]

Hello,
1. Use structure BAPIPAREX for passing custom fields. (There are several blogs/posts on how to make use of this).
2. In the BAPI i noticed there is a BAdI to populate these fields into your business tables.
Call BAdI MB_BAPI_GOODSMVT_CREATE to fill own fields
    TRY.
        get badi lo_mb_bapi_GOODSMVT_CREATE.
      CATCH cx_badi_not_implemented.                    "#EC NO_HANDLER
    ENDTRY.
    TRY.
        call badi lo_mb_bapi_goodsmvt_create->extensionin_to_matdoc
          EXPORTING
            EXTENSION_IN = EXTENSIONIN[]
          CHANGING
            CS_IMKPF     = S_IMKPF
            CT_IMSEG     = T_IMSEG[]
            CT_RETURN    = return.

How can I implement IMAQ correlation for 16bit image?

Hi
When using IMAQ correlate. vi in Machine vision Filter catergory, the vi only works for 8 bit source and template image case.
16 bit source image case makes error.
But I need 16 bit source image without losing image information, I want to use full 16 bit image correlation with 8 bit template.
How can I implement the code in labview?
Need help.
Many thanks.

Unfortunately you can't do so.
There are some functions in the Vision Lib that only accept 8bit images. In order to use them you have to convert your image to an 8bit Image.
Keep in mind that converting an Image to 8bit will not necessary result in a loss of data. Check your Images, it might be that you are not using the full range of a 16bit value. you might be able to use a mixture of dynamic shifting and bit shifting in order to convert an image to an 8 bit, then embedding these criterias in the image and use them to convert back to a 16bit at a later time without losing any data, or in most cases minimal precision loss.
If you would like to attach one of the images you are using, I can take a look at it to see if this is possible in your case.
Good luck,

How can I implement Authentication in LDAP

How can I implement Authentication in LDAP.

Hi,
If ur using JAAS, then use NTLoginModule in ur conf file and your own defined CallbackHandler for validating and obtaining the Subject (user connected to your domain).
Remember the user is the one which the code obtains when u login to your Domain based machine.
Apart from this, Apache Http Server also provides you with a popup window asking for the user's credentials when u set the SSPIDomain in the httpd.conf file.
httpd.conf
========
<Location /Seet/servlet/ >
SSPIAuth On
AllowOverride None
Order allow,deny
Allow from all
AuthName "seet190 auth"
AuthType SSPI
SSPIAuth On
SSPIAuthoritative On
require valid-user
SSPIDomain seet190
</Location>
seet190 is the domain name
Actually so far in the Security Forum, u might refer to some of the replies posted for more help but actual LDAP authentication can be done by passing the user's info too.
HTH,
Seetesh

How can I implement recipe control concept in SAPME?

Dears,
How can I implement recipe control concept in SAPME?
For example,
We can config the standard temperature setting needs to be between 100~120 degree C for Operation OP1 and Material MA1
So, before user start the SFC of MA1 at OP1, system can display the config values(100~120) for user reference, then, user need to input the real temperature when process the SFC, if it's out of spec, system can warning. System will collect the input data for analysis in future.
Thank you.

Thank you for your information.
Since customer prefer to use a custom UI which can communicate with SAPME by web service.
So I can not use SAPME default data collection or work instruction user interface.
I'm considering by using data collection and work instruction config data to develop a web service in MII and poblish to custom UI in which it can display the spec data and reject user's input if out of spec.
Please feel free to inform me if any other good idea, thanks!

How can I use the field "Sales Order" on derivation?

Dear All.
This is about PA characteristic derivation.
I want to change the characteristic value "Sales Order (KAUFN)" by derivation.
But I cannot select the characteristic field on target field.
The field "Sales order(KAUFN)" doesn't exist there.
Why? How can I use the field "Sales Order" on derivation?
Y.C.Bae

Hi Bae,
in order to be able to choose fields KAUFN (for sales order) and KDPOS
(for sales order item) as target fields of derivation step 'enhancement'
you have to modify the coding of subroutine EXIT GET_ALLOWED_TARGETS
in program RKEDRCOPA like this:
    NAME-IDENTIFIER = 'CO-PA'.
    NAME-TABNAME = FIELDTAB_ENTRY-TABNAME.
    NAME-FIELDNAME = FIELDTAB_ENTRY-FIELDNAME.
    IF FIELDTAB_ENTRY-USGFL CA 'DUV'
BEGIN OF INSERTION *****
         OR FIELDTAB_ENTRY-FIELDNAME = 'KAUFN'
         OR FIELDTAB_ENTRY-FIELDNAME = 'KDPOS'
END   OF INSERTION *****
         OR FIELDTAB_ENTRY-FIELDNAME = 'KNDNR'
         OR FIELDTAB_ENTRY-FIELDNAME = 'ARTNR'
Actually sales order number and sales order item shouldn't be changed
by derivation (therefore they are no valid target fields in standard)
but if you need to fill them within an enhancement this modification
will help you to define them as valid target fields. But this is just
the technical frame so far; the logic from which table you'd like to
derive the sales order number correctly depends on your implementation
of the enhancement! I just want to ask you to be rather careful with
the implementation of the exit so that the sales order number isn't
changed in cases that shouldn't be concerned.

Abhisek

Having arranged some scanned pictures in an album in I-Photo how can I keep them in the order I have chosen when I move the album. They all have the scan date and not the taken date and move to new positions if I move them from one album to another.

Having arranged some scanned pictures in an album in I-Photo how can I keep them in the order I have chosen when I move the album. They all have the scan date and not the taken date and move to new positions if I move them from one album to another.
Is there any way to re-number them in the order I have chosen so that they can then be sorted by number? The scans are all from pre-digital images that I wish to move to a photobook and I don't want to have to organise them twice!
Thanks for any suggestions.

I was a bit short, Chris, sorry. It is limited, what can be posted, when typing on an iPad.
Now I am back on my Mac. I meant the following: Batch Change the date for a large range of photos, that should have a date stepped in increments.
Select all Photos at once and use the command "Photos > Batch Change".
Then set the date for the first photo and select an increment, e.g. one minute.
Now all photos will get a new date assigned, incremented by one minute, in the sequence you have selected. So you will be able to sort them by date. This way it will be unnecessary to change the titles or filenames.

Welcome to the Apple Community.
I don't think you can. You might ensure that their creation dates are in order, but I'm not so such that will help. Ordering seems to be a feature limited to use with iPhoto/Aperture.

My photos are out of chronological order after the os 5 upgrade. How can I get them back in order?

My photos are out of chronological order after the os 5 upgrade. How can I get them back in order?
If its not possible, how do I go back to the old os?

I had tried that several times with no luck. Late last night I was finally able to get through to the Verizon technical support who then called in Apple technical support. It took 1 1/2 hours for them to figure it out and guide me through a fix. So here's the deal .......... I use Yahoo mail and had left the "contacts" button in the on position. Apparently Yahoo likes to go into your contacts and gather information and can leave it in shambles. My advice is, go to settings, then mail, contacts, calendars. Select any and all of your email accounts and go in and turn off their access to your information. Leave it on for Icloud but none of the others.

How can I implement a real time datawarehouse

Hi, I'm a little lost here but I want to know how can I implement a real time datawarehouse in sql server, I don't know if it is only to make the extraction process the shortest time possible.
Thank you

Hi Mega15,
I agree with everything Seif and Louw said, but I'd like to add that if you are using SQL Server 2012 or 2014 and you want to use DirectQuery or ROLAP mode (depending on what SSAS mode are you using, tabular or multidimensional) you may be interested on
using columnar indexes on your base tables.
Analytical and aggregated queries will take GREAT advantage from these indexes, they will perform much better than with traditional B-Tree indexes in most of your scenarios.

Pau.
