Sum 2d arrays with different columns width

hi,
I have a 2d array that stores the number of rats in X number of houses.
in each row, i have the number of rats per house (length) and the weight of each.
So, if I have 3 houses, I would 3 rows (0,1,2).
And, in house 1: I have 2 rats (0,1)
then, rat1 weights 20, rat2: 15
in house 2: I have 3 rats (0,1,2)
rat1: 30, rat2: 25 rat3: 5
in house 3: I have 1 rat (0)
rat1: 50
So, what I need to do is to calculate the total weight of rats per house and display:
Total weight in House1: 35
House2: 60
House3: 50
I dont know how to do the sum and display the sum for each house. Any hints/solutions?

> yeah, but I am still looking for a way to sum every
column per row.
You've been given the same solution on two different forums. If you know how to loop through the houses, you know how to loop through the rats. The "rat loop" will be nested inside the "house loop". Each rat will be identified by two indices; the house index and the rat index. Just loop through the rats, adding each rat's weight to the total for that house.

Array to different columns

Hello,
In the attached VI, I am currently getting all the arrays to show up in the same columns. I am trying to show each pass in the attached VI to show as different colums in the string table.
Any help will be appreciated.
Thanks,
hiNi.

I would allocate a string array at the final size, then replace data as you go. Here's quick rewrite (LabVIEW 8.5).
(I don't understand your use of the local variable, sequence structure, and while loops. The first two are not needed and the loops should be FOR loops because you know the number of iterations beforehand.
(Also note that you should work with strings for the final table. A numeric array will be padded with zeros for undersized rows or columns. An empty string for missing elements seems more appropriate.)

BO xi 3.1 u2013 schedule a template for multiple reports with different column

Hi,
I need to migrate the existing reports from SQL Server Reporting Services to BO, and the column order in the report is very important to the clients since clients have existing code to ingest these reports into their database. Now I want to schedule a single template with different parameters for all reports in BO, or create a single template with lot of parameters for all reports. My question is how I might use one template to create multiple reports with different column orders in the reports?
For example, client A has the following column order in their report: firstName, LastName, DateBirth, SSN. Client B has the following column order in their report: SSN, DateBirth, LastName, FirstName. Can I use one template to create these multiple reports?
Thanks!

Hi,
The only approach I can think of is to create a template report which uses variables
For each column you would need to variable
v_columnAName and v_columnAValue
v_columnAName would have a if statement in it
=if([client]="clientA" or [client]="clientC";NameOf([firstName]);if([client]="clientB";NameOf([SSN]);NameOf([lastName]));
v_columnA would have a if statement in it
=if([client]="clientA" or [client]="clientC";[firstName];if([client]="clientB";[SSN],[lastName]));
This would only work when you had a small set of clients.
This might be more managable if it was done in the universe

Is it possible to create a Synonym with different column names

Hi,
I want to create a Synonym with different columns names (Columns not in original table) . I am not sure if this can be done . Any suggessions...
Thanks in advance....

Synonyms are not limited to tables. Accroding to the SQL Reference, a synonym is:
an alternative name for a table, view, sequence, procedure, stored function, package, materialized view, Java class schema object, user-defined object type, or another synonym.
In fact, synonyms are not even validated until they are used:
SQL> create synonym my_synonym for table_which_does_not_exist;
Synonym created
SQL> select * from my_synonym;
select * from my_synonym
ORA-00980: synonym translation is no longer valid

How to generate and output 3 TTL square waveforms with different pulse widths using counters of NI 6034E

Hello
I just have a few questions.
I am using the NI 6034E DAQ board in order to
generate simultaneouly 3 different TTL digital signals, with different
pulse width, and output these TTL signals to an external circuit that I
am using for this application.
The following pattern of the TTL pulses will look like this:
01010101 01010101
00110011 00110011
00001111 00001111
From
what I understand, I have to use the 2 counters, Ctr0 and Ctr1, to
generate the TTL pulses that I desire, because the DIO lines are
software timed only and I will not be able to produce a deterministic
output period using these DIO lines. Am I correct? Also, do I have
to use a separate counter to generate a separate TTL digital pulse. I
need 3 different TTL pulses and there are only 2 counters for this DAQ
device. The three generated TTL signals will be feed to an external
circuit. Concerning the hardware connections for my application, I
assume that the generated TTL signals will be output from
GPCTR0_OUT(pin 2) for counter 0 and GPCTR1_OUT(pin 40) for counter 1
of the NI 6034E. Is this correct? Is there any way that these TTL
signals can be output from three DIO lines(DIO0...2).
Here is some code that I plan to use in order to do this:
#include <NIDAQmx.h>
static TaskHandle gTaskHandle = 0;
DAQmxCreateTask ("", &gTaskHandle);
DAQmxCreateCOPulseChanTime (gTaskHandle, "Dev1/ctr0", "", DAQmx_Val_Seconds, DAQmx_Val_Low, 1.0, 2.0, 2.0);
DAQmxCreateCOPulseChanTime (gTaskHandle, "Dev1/ctr1", "", DAQmx_Val_Seconds, DAQmx_Val_Low, 3.0, 4.0, 4.0);
DAQmxCreateCOPulseChanTime (gTaskHandle, "?????", "", DAQmx_Val_Seconds, DAQmx_Val_Low, 7.0, 8.0, 8.0);
DAQmxCfgImplicitTiming (gTaskHandle, DAQmx_Val_FiniteSamps, 5);
DAQmxStartTask (gTaskHandle);
DAQmxWaitUntilTaskDone(gTaskHandle)
DAQmxErrChk DAQmxStopTask(gTaskHandle)
DAQmxErrChk DAQmxClearTask(gTaskHandle)
I believe this code should generate the 3 TTL square waveforms that I want for my application.
Please provide me with some feedback. It would greatly be appreciated.
Thank You

Hi,
The NI 6034E is a multifuntion DAQ device, this means you have:
(2) counters
(8) DIO lines (software timed)
(16) AI, single ended
(0) Analog Output
You have a couple choices here:
 1. Software timed digital output of all three signals, max 1khz loop rate, non-deterministic.
 2. Hardware timed digital output of 2 signals, max 20Mhz.
 3. Hardware timed digital output of 2 signals and software timed digital output of 1 signal.
 4. Find another NI MIO board such as the NI 6251. This board will do 10Mhz pattern generation for (8) DIO lines.
For the hardware connection, you are correct, the output for the counters will be taken from pin 2 & pin 40. Here's the pinout for the NI 6034E for reference:
The output of the Counters can be routed to some of the PFI's or to the RTSI connector. You can see this in MAX

How to generate a pulse train with different pulse width and delay?

How to generate a triggered pulse train with different pulse width. for example, after each trigger signal, let's say 2 ms, then the counter output a pulse with pulsewidth of 1 ms, and then after 3 ms delay after the first pulse, the second pulse was generated with a pulse width of 4 ms. Next cycle when the trigger signal comes, the same two pulses will be generated and so on. Is it possible to achieve this by using 6601 counter card? and if yes, how to achieve this? Thanks!

Unfortunately you can not create a hardware timed pulse train with different widths on each pulse from a counter. Whilst it can be changed on the fly using software, since you require a hardware triggered signal getting the software involved will not give a huge amount of accuracy when the pulse will actually change.
So in short you can't use your 6601 card (or a counter timer) to achieve this
There are three possible Alternative solutions
1 You could use a high speed digital IO device such as the (6533/34) to generate your variable signal which would require setting up the pulse train as a series of states based around the burst transmission mode where the clock would give you your specific timing.
2 A timed analogy output (for example on a MIO card with a clock (PCI-6220 / 62xx), i.e. Not the 6704 style static analogy output cards)
3 A high speed digital waveform card such as the (, 656x , 655x, 654x, 6534, 6533 (http://www.ni.com/modularinstruments/find_right.htm) ) this could then be scripted to work with your triggering and also there is a digital waveform editor which will enable you to set up the pattern you wish to generate (http://sine.ni.com/nips/cds/view/p/lang/en/nid/13555)

BI Answers - need 2 compound layouts with tables with different columns

Hi,
I need 2 tables in the same report with different columns displaying. Is this possible?
I wanted to put them in their own compound layout and call each one with a view selector,
but it seems impossible to create a 2nd table with different columns in the one report.
Each time I try and replace one of the columns in the 2nd table with a different column,
a message appears saying the deleted column will be deleted from all views.
Many thanks for anyone's help.
- Jenny

As per my knowledge - your requirement can be done with Pivot view but not with regular table view.
We dont have exclude column - functionality in table view.
Else, instead of creating in same report create the req. with 2 separ. reports but place them on single dashboard in 2 sep. sections.

Design a single template for multiple reports with different column order

Hi,
I need to migrate the existing reports from SQL Server Reporting Services to Crystal Report 2008, and the column order in the report is very important to the clients since clients have existing code to ingest these reports into their database. Now I want to create a single template with lot of parameters for all reports. My question is how I might use one template to create multiple reports with different column orders in the reports?
For example, client A has the following column order in their report: firstName, LastName, DateBirth, SSN. Client B has the following column order in their report: SSN, DateBirth, LastName, FirstName. Can I use one template to create these multiple reports?
Thanks in advance.

-As I mentioned you can find Template Field object in Insert menu of crystal report Designer 2008.
As soon as you select Template Field object you will be able to see a box beside ur mouse cursor. Drag and drop this box at required place. Now when you place this object in report you will get some thing like this "<TemplateField1>" listed under Formula Fields tree. Double click "<TemplateField1>" formula to add your conditions.
-I have not tested it for large amount of Customers. However as the number of customer increases the number of conditions will get increased.
For the customer that want the same ordering of columns you can put those customers under one condition.
 for Example...
 if(?Client in ['clientA','clientA']) then
 <TableName>.<Field>......
-What do you mean be 40 columns? Do you mean 40 fields or you want to show 40 columns in report? Please elaborate.

Amrita

Many to many join table with different column names

Hi have a joint table with different column names as foreign keys in the joining
tables...
e.g. i have a many to many reltnshp btwn Table A and Table B ..and join table
C
both have a column called pk.
and the join table C has columns call fk1 and fk2
does cmd require the same column name in the join table as in the joining table?
are there any workarounds?
thanks

HI,
No, the foreign key column names in the join table do not have to match the primary
key names in the joined tables.

Grid with fixed column widths

Hi Folks,
I have a grid in which I want to prevent the user to move the set column widths, because this grid has a separate graphik on top of it which would then cease to correspond with the grid columns.
My question: is there any means of difining a grid with non-resizeble columns?
Thanks & Regards

Hi,
If your table is based on a view object then you can use a transient attribute and in its value use a groovy expression.
the new attribute should have:
value type: "expression"
value: object.getRowSet().sum('AmountAttribute')"
Drag and drop the new attribute from the data sources to your page and add partialTriggers from the components that affect it
(Insert/Delete buttons and the table field that it sums).

Spark DataGrid with Dynamic Column Width

Lets suppose I have a Spark Datagrid with no explicit typicalItem. When the Datagrid is initialized, the column widths are calcualted correctly based on the contents of the dataprovider. However if I add/remove an item from the dataprovider, or modify the one of the objects in the dataprovider, the column widths never update to reflect the change. Is the the correct behavior for a DataGrid? If so, is there any method I can call to force the DataGrid to recalculate and redraw the column widths?

When Spark DataGrid doesn't have a typicalItem, it uses the first dataProvider item as the typicalItem. If you change that, the DataGrid won't pick it up immediately. You can invalidate the current typicalItem using dataGrid.invalidateTypicalItem().

Stuck - load the Excel file dynamically with different columns and worksheet names

I have a situation where I want to load the Excel file dynamically, and the excel file have different columns or even worksheet name. Any idea how I could
approach this? I believe there's no way to modify the meta data (specifically the mapping) in the data flow.

Hi Chimumu,
The SSIS stock adapters don't supporting dynamic column mapping, to achieve your goal, you need to use Script Task/Component to read the Excel sheet name and the columns in the worksheet, and then map to the output columns of the script component. You can
also refer to the following blogs:

Passing data to different internal tables with different columns from a comma delimited file

Hi,
I have a program wherein we upload a comma delimited file and based on the region( we have drop down in the selection screen to pick the region). Based on the region, the data from the file is passed to internal table. For region A, we have 10 columns and for region B we have 9 columns.
There is a split statement (split at comma) used to break the data into different columns.
I need to add hard error messages if the no. of columns in the uploaded file are incorrect. For example, if the uploaded file is of type region A, then the uploaded file should be split into 10 columns. If the file contains lesser or more columns thenan error message should be added. Similar is the case with region B.
I do not want to remove the existing split statement(existing code). Is there a way I can exactly pass the data into the internal table accurately? I have gone through some posts where in they have made use of the method cl_alv_table_create=>create_dynamic_table by passing the field catalog. But I cannot use this as I have two different internal tables to be populated based on the region. Appreciate help on this.
Thanks,
Pavan

Hi Abhishek,
I have no issues with the rows. I have a file with format like a1,b1,c1,d1,e1, the file should be uploaded and split at comma. So far its fine. After this, if the file is related to region A say Asia, then it should have 5 fields( as an example). So, all the 5 values a1,b1..e1 will be passed to 5 fields of itab1.
I also have region B( say Europe) whose file will have only 4 fields. So, file is of the form a2,b2,c2,d2. Again data is split at comma and passed to itab2.
If some one loads file related to Asia and the file has only 4 fields then the data would be incorrect. Similar is the case when someone tries to load Europe file with 5 fields related data. To avoid this, I want to validate the data uploaded. For this, I want to count the no. of fields (seperated by comma). If no. of fields is 5 then the file is related to Asia or if no. of fields is 4 then it is Europe file.
Well, the no. of commas is nothing but no. of fields - 1. If the file is of the form a1,b1..e1 then I can say like if no. of commas = 4 then it is File Asia.But I am not sure how to write a code for this.Please advise.
Thanks,
Pavan

Mailboxes with different column headings

This question was somewhat covered in 2006-2007 but not recently. I would like to set different column headings for certain mailboxes in Mail. I understand that the Inbox folder keeps a "logical" set of columns (From and not To, for example). The folder Sent also behaves the same. But I have organized most of my Received messages in a folder which then has subfolders for each company or person or sets of persons. I also organized my Sent messages in separate into a Mailbox called Sent Messages with appropriate subfolders/mailboxes. I would like to keep all of the Mailboxes that "receive messages" with certain columns (such as From and not To) and the "sent messages" with a different set of columns (To instead of From, Date Sent instead of Date Received, etc...). But I cannot do that in Mail 5.3 running on MacOS 10.7.5 . Is there a solution to achive these settings permanently?
Thanks for any suggestion.

Hello, I see this is an old post but is marked as solved. Did you find a way to do this? I've been looking for a way but to no avail.
