Question re-posted: Way to get events from outside application

Hello,
FatCo asked this question but has not got a reply. I have the same question, so I re-post it, hoping someone could give us help. How can we write JNI code to do it on a Windows OS? Assume appliction 2 is a Internet Explorer.
Thank you!

Hello,
is there a way to get events from other applications, either native or java applications?
For example application 1 (Java or not) is getting minimized, is there a way to notice application 2 (Java) about that?

I am not really a Windows programmer so I cannot say how you can get the event notification in C(++) but if you can get it there then there should be no particular problem communicating that information to Java.
This might take the form of creating a thread (all threads are native threads on Windows) which blocks on receiving this event and then notifies the rest of the application somehow, maybe by setting a global flag, using Object.notify() to wake up some other thread to do the processing, or simply by calling a Java method to do all the necessary handling before returning. But there is nothing special about this part.
It all depends on how you can receive the event notification in C++.

Best way To get data from another application using NDDE lbrary

My vb.net application gets data from another application using NDDE Library. I got stocks prices (open,high,low,close,volume,change......(about 15 records for each stock)) (about 200 stocks) . I don't know if there is a problem in my code.
This is my code:
l : is the list of stocks.
This Sub connects to server and requests the data :
Public Shared Sub GetQuotes()
Try
client1 = New DdeClient(server, topic)
client1.Connect()
For i As Integer = 0 To l.Count - 1
client1.StartAdvise("QO." & l(i).t & ".TAD$last", 1, True, 60000)
client1.StartAdvise("QO." & l(i).t & ".TAD$open", 1, True, 60000)
client1.StartAdvise("QO." & l(i).t & ".TAD$high", 1, True, 60000)
client1.StartAdvise("QO." & l(i).t & ".TAD$low", 1, True, 60000)
client1.StartAdvise("QO." & l(i).t & ".TAD$pclose", 1, True, 60000)
client1.StartAdvise("QO." & l(i).t & ".TAD$volume", 1, True, 60000)
client1.StartAdvise("QO." & l(i).t & ".TAD$date", 1, True, 60000)
client1.StartAdvise("QO." & l(i).t & ".TAD$time", 1, True, 60000)
Next
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Sub
and then I get the data from Client_advise sub (called each time a value changed )and fill the list. What I know is that client advise gets only one record for single stock each time is called..
Example: for stock AAPL. 1st time enters client_Advise I get open price for AAPL, 2nd time I get high price for AAPL,3rd time I get low price..... and I update the value in the List (l)
This the client_Advise Sub:
Private Shared Sub client1_Advise(ByVal sender As Object, ByVal e As NDde.Client.DdeAdviseEventArgs) Handles client1.Advise
For q As Integer = 0 To l.Count - 1
If l(q).t = w(1) Then
Dim item() As String = e.Item.Split("$")
If l(q).Open = "#" Then
l(q).Open = "0"
End If
If l(q).hi = "#" Then
l(q).hi = "0"
End If
If l(q).lo = "#" Then
l(q).lo = "0"
End If
If l(q).Close = "" Or l(q).Close = "#" Then
l(q).Close = "0"
End If
If l(q).pclose = "#" Then
l(q).pclose = "0"
End If
If item(1) = "open" Then
l(q).Open = Format(Val(e.Text), "0.00")
ElseIf item(1) = "last" Then
l(q).Close = Format(Val(e.Text), "0.00")
ElseIf item(1) = "high" Then
l(q).hi = Format(Val(e.Text), "0.00")
ElseIf item(1) = "volume" Then
l(q).Volume = Val(e.Text)
ElseIf item(1) = "low" Then
l(q).lo = Format(Val(e.Text), "0.00")
ElseIf item(1) = "pclose" Then
l(q).pclose = Format(Val(e.Text), "0.00")
If l(q).pclose <> "" And l(q).pclose <> "#" And l(q).Close <> "" And l(q).Close <> "#" Then
l(q).c = Format(l(q).Close - l(q).pclose, "0.00")
l(q).cp = Format(((l(q).Close - l(q).pclose) / l(q).pclose) * 100, "0.00")
End If
l(q).flag1 = 2
ElseIf item(1) = "date" Then
l(q).Date1 = e.Text
ElseIf item(1) = "time" Then
l(q).Time = e.Text
End If
Exit For
End If
Next
End Sub
Am I doing something wrong which inreases CPU usage to 80 or 90 % ?
Thanks in advance.

Hi MikeHammadi,
According to your description, you'd like to get data from another app using NDDE library.
When using the NDDE library, the CPU usage is high. As the NDDE library is third-party library, it is not supported here. I suggest you checking if the problem is caused by the NDDE library.
If you'd like to get data from another app. I suggest you could save the data in the dataBase, and then read it in another application if necessary.
If you have any other concern regarding this issue, please feel free to let me know.
Best regards,
Youjun Tang

Now i cannot understand that how can i set action and get event from the?
And how can i set various views on three tab bar item.
I have to use UITabBar means i have to use UINavigationController+UITabBar
My code id
tabBar =[[UITabBar alloc] initWithFrame:CGRectMake(0,370,320,50)];
tabBar.backgroundColor =[UIColor blackColor];
UITabBarItem *search =[[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemSearch tag:0];
UITabBarItem *recents =[[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemRecents tag:1];
UITabBarItem *favorites =[[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemFavorit es tag:2];
tabBar.items =[[NSArray arrayWithObjects:search,recents,favorites, nil] retain];
tabBar.selectedItem = search;
[myView addSubview:tabBar];
[tabBar release];
I add a action:

So it error: Warning -no'InitWithTabBarSystemItem:tag:action:' method fount
So any can help me regarding it?

Thanks RickMaddy very much.

You should be able to copy it from your iPhone to your computer's iTunes via File > Devices > Transfer Purchases, and if it's compatible with your iPad you can then sync it to it

I cannot find the eMac install disk, and I haven't been able to get it to start up from my 10.3 CDRm (holding down option or c), though I read something somewhere about these not being able to start up from system folders earlier than those they shipped with. I've dealt with this sort of thing several times before, and it always seemed to work to simply use target disk mode.
It definitely won't start up fromt the 10.5 DVD-R, and I'm pretty sure I tried putting the MBP into TM to use its optical drive as well, but it didn't work. But it's worth trying again, and I appreciate your input greatly.

I could connect any application from inside the firewall (basically router) and can not access screens from outside. Eventhough port forwarding 80 allows us upto initial screen, it does not go further.
Any workaround/suggestions
Jiltin

Hi Jiltin,
If you can migrate your forms server into Forms Listener Servlet.This will allow you to use forms outside firewall provided atleast one port(assuming yours 80) is open.
Ref to the M.Link Note 201340.1 for how to setup forms listener servlet.

What are the diffrent ways to copy data from one application to another?

Hi,
Can you guys tell me what are the different ways to copy data from one application to another application??
I know we can do it through script logic using DESTINATION_APP.
Is there any other way to copy data from one application to another application?
Please help me
Thanks,
Charly

You can also call a custom DTSX package in SSIS via the datamanager.
there are at least 5 ways of transfering data in BPC between apps.
1. Through the front end (excel etc) via evdre/evsnds
2. Through Script logic using *Dest App
3. Using BPC's standard export dtsx package via DM
4. Using SSIS using BPC's custom SSIS tasks
5. Through Script logic using stored procs.
i am sure people will come up with more.
remember if you use ssis and move data into any table but the wb, you need to process the cube afterwards.

ALV Grid editable - How to raise the data_changed event from outside object

Hi,
i'd like to like to raise the data_changed event from outside the ALV-Grid object in order to display errors to the user.
For example a new row was inserted within the program. The user has only to complete the missing informations. Before saving the transactions the program has to execute some semantic checks. The errors of this check process should be shown to the user by creating an instance of the cl_alv_changed_data_portocol object.
Thanks.
Regards

You don't need to raise the data_changed event to perform the edits or to issue messages using cl_alv_changed_data_protocol.
The following assumes you have an ALV grid object g_alv based on the CL_GUI_ALV_GRID class.
You can mark the inserted records upon insertion as selected using the set_selected_rows method, and then retrieve these rows later using get_selected_rows and perform necessary edits.
Save the row number of each inserted row into a table of the appropriate type (see the method definition for this):
DATA: t_index_rows    TYPE lvc_t_row.
DATA: s_row_no        TYPE lvc_s_roid.
DATA: t_row_no        TYPE lvc_t_roid.
Load entries into t_row_no after each insert. Capture the row number and save in the table t_row_no.
e.g.
PERFORM insert_row USING s_row_no-row_id.
APPEND s_row_no TO t_row_no.
FORM insert_row would have whatever code you are using to insert the row. Save the row id into s_row_no-row_id (which is an INT4).
When done with all inserts do the following
IF t_row_no[] IS NOT INITIAL.
    CALL METHOD g_alv->set_selected_rows
      EXPORTING
        it_index_rows            = t_index_rows
        it_row_no                = t_row_no
        is_keep_other_selections = 'X'.
ENDIF.
Then, if SAVE is pressed without the data_changed event having been raised (such as if the user just pressed SAVE without changing anything), use method get_selected_rows to retrieve the rows that were inserted and perform the necessary edits.
DATA: l_t_rows    TYPE lvc_t_row.              " ALV control: Table rows
CALL METHOD g_alv->get_selected_rows
    IMPORTING
      et_index_rows = l_t_rows.
Loop through l_t_rows and use the row as an index into the grid, perform the necessary edits, just as you would if the data_changed event had been raised.
If any edits fail, then send messages to the user, abort the save, and re-display the grid.
Remember to refresh the t_row_no and t_index_rows tables if you load a new data set.
You can also use a similar technique with the data_changed event to mark each changed row as selected by saving the row ids, and then you only have to update the changed rows on SAVE, which can minimize database I/O.
Good luck.

Is there any way of getting back from a wrong clicked free trial to add my serial number correctly?

Hi
On purchasing a new imac I copied the apps across & on opening CS6 was requested to load serial numbers, through tiredness I added the seria; number from CS5.5 and therefore not recognised for the CS6, then when about to enter again through tiredness I must have clicked free trial and now have the CS6 in that format.
Is there any way of getting back to that initial box to load the correct numbers & get out of trial as although it works I need it set up correctly?
Any help appreciated

Sorry, cant see this visible on menu or drop downs, did run through all menus before posting, could just be tired from 3 weeks straight.
If this is not an option does that mean I am set up ?

Fastest way to get data from Multiple lists across multiple site collections

HI
I need to get data from multiple lists which spread across 20 site collections and need to show it as list view.
I have searched on internet about this and got some info like options would be to use search core APIs or BCS . I can't use search because I want real time data. Not sure of any other ways.
if anybody can provide ideas it would be help.

Might LINQ be an option for you? Using
LINQPad and the
SharePoint Connector, you should be able to write a query that'll retrieve this data, from which you can tabulate it. I'm not sure how you'd be able to automate this any further so that it's then imported in as list.
For something more specific, I used a third party tool called the
Lightning Tools Lightning Conductor, which is essence a powerful content roll-up tool. In one of my solutions, I created a calculated column that gave an order / ranking on each item, so that when lists were combined, they'd still have some form of
order. The web part is also fairly customisable and has always proven a useful tool.
Hope that helps.

Best way to get data from multiple table

Hi.....
Say we are having two data base tables.. ZMODEL1 and ZMODEL2...
Now decalre intrenal tables and work areas and before that structures for these two and also declare one final output table for display the data...
>types: begin of ty_model1,
>       za(10),
>       zb type netwr,
>       zc(10),
>       zd(10),
>       ze(10),
>       zf(10),
>       end of ty_model1,
>       begin of ty_model2,
>       za1(10),
>       zb1(10),
>       zc1(10),
>       zd1(10),
>       za(10),
>       end of ty_model2,
>       begin of ty_output,
>       za(10),
>       zb type netwr,
>       zc(10),
>       zd(10),
>       ze(10),
>       zf(10),
>       za1(10),
>       zb1(10),
>       zc1(10),
>       zd1(10),
>       end of ty_output.
>
>data: t_model1 type standard table of ty_model1 initial size 0,
>      t_model2 type standard table of ty_model2 initial size 0,
>      t_output type standard table of ty_output initial size 0,
>      w_model1 type ty_model1,
>      w_model2 type ty_model2,
>      w_output type ty_output.
Now in the start of selection.. event...
>select <field names in the same order as in database table> from zmodel1 into table t_model1 where za in s_comp. (s_comp is select-option for that field)>
>if sy-subrc = 0.
>select <field names in the same order as in database table> from zmodel2 into table t_model2 for all entries in t_model1 where za = >t_model1-za.
>endif.
After that now fill the final output table...
>loop at t_model1 into w_model1.
> w_output-za = w_model1-za.
> w_output-zb = w_model1-zb.
> w_output-zc = w_model1-zc.
> w_output-zd = w_model1-zd.
> w_output-ze = w_model1-ze.
> w_output-zf = w_model1-zf.
>
>read table t_model2 into w_model2 with key za = w_model1-za.
>if sy-subrc = 0.
> w_output-za1 = w_model2-za1.
> w_output-zb1 = w_model2-zb1.
> w_output-zc1 = w_model2-zc1.
> w_output-zd1 = w_model2-zd1.
>endif.
> append w_output to t_output.
> clear w_output.
> end loop.
and now display the final out table...
This is the best way..
Thanks,
Naveen.I
