How do I generate formula with column of text?
I have a list of attendees to an upcoming party. Three columns - First Name, Last Name, Attendance.
In the "Attendance" column I have created drop down menues with 4 different text values regarding their attendance (Yes, No, Maybe, No Reply).
At the top of the page I would like to have a quick list table referencing the text values and count; would look like this:
Yes - 34
No - 12
Maybe - 24
No Reply - 13
How do I create this quick list with number count since the values in the "Attendance" column are text.
Thank you kindly!
Okay hotshot, I'm stuck again.
Now I want to gather the number of "Yeses" from two different tables. This is what I have tried so far but am stuck: =COUNTIF(Terry Allen :: Attendance,Ron Allen :: Attendance,"Yes")
There error message I received was "Countif requires 2 arguments, but was given 3."
I do have a way around it; just use your previous formula to tally up the number of yeses at the bottom of each table, and then sum it all up, but I would rather just cut to the chase and have it formulate directly in my quick list table at the top of the page.
Any thoughts? Thanks.

How I tie the formula with conditions type?
Hi,
Than create the formula with tcode O3I7:
1) how I tie the formula with conditions type?
2) how I tie the conditions type with the formula with Calculation Schema?
help me, please.
thanks
Edited by: celeste ziantoni on Feb 5, 2008 6:45 PMHello,
Pricing formula is created using transaction VOFM. It is tied to the condition types in Pricing Procedure definition in Alternate Calculation Type column. For Pricing procedure, the menu path is SPRO->Materials Management->Purchasing->Conditions->Define Price Determination Process->Define Calculation Schema.

How to Create a Auto Generated number with some preceding text in Sharepoint 2010
I am trying to create a auto generated number field in Sharepoint 2010 list item. My requirement is to have the following format number generated when new request is created in Sharepoint using form. Auto generated Ticket ID should be in the following format
"IR13000" "IR13001" "IR13002"....... Please let me know how to get this done. I tried to use combination of default ID and Characters but its not working for new requests, its only reflecting for existing uploaded requests. I
am trying this for taking up Ticket requests by filling up some fields in the form. Any quick help is much appreciated.
ThanxHere are the steps:
1 - Open your SharePoint site in SP Designer 2010.
2 - Click Workflows and add a List workflow. Associate this workflow on the list where you want the Random Text to be generated.
3 - Inside the workflow editor, select the Action "Update list item"
4 - Select 'Current Item'.
5 - Click Add.. and select the field which needs to be updated with the Random Text. Make sure this column is not of type "Calculated" type, otherwise you won't see it in the list of the fields within the workflow.
6 - Click "..." button in the next textbox which will open String Builder dialog box.
7 - Type IR and then click 'Add or Change Lookup and select ID column from "Field from source". Hit OK.
8 - It should look like IR[%Current Item:ID%]
9 - Hit OK.
10 - Save and publish the workflow. (Please note that currently this workflow is not set to auto run on creating new items. That's because we want to test it at this point of time).
11 - Go to your list in SharePoint and create a new item. After creating, select the item and click Workflows and then run this workflow.
12 - You should be able to see the text "IR1" in the designated column.
13 - Once you see that it's working, go to SPD and set the workflow to run automatically on creation of the new item. Save and publish and then return to your list in SharePoint.
14 - Create a new item there and you should see the Random value in the column.
15 - You will also see the column in the New form. In order to remove it, go to List settings > content types > Item content type > and select Hidden for this column so that it doesn't showup in any form.
Try it and let me know how it goes.
Thanks,

How can we generate javadocs with Jdev3
Hello,
I'm using JDeveloper3 to create some javabeans. I don't know how I can generate javadocs from JDeveloper3 with JDK1.2.2
NicolasWith this information I don't think, that the 7334 is the right board for your application. The 7334 is a motion control board for stepper motors. As control signals it provides a step signal with variable frequency and a direction signal (high or low for fwd. or rev. direction). The step signal is generated onboard and controls the motor's trajectory (acceleration, velocity, travel distance). The duty cycle of this signal can't be changed by the control program, so this signal can't be used for your application.
The PWM outputs provided by the 7334 is static. That means, you can set frequency and duty cycle only in software, which is quite slow and introduces significant and non-deterministic jitter (due to the asynchronous communication to the 7334 this is even true if you are using a real-time operating system). These limitations don't seem to meet your requirements.
I still don't have a good idea about your timing requirements. If your response times requirments are in the upper milisecond regions (10 ms and above), you might be able to use the 7334. If low jitter and fast response times are important to your application, there are several alternative solutions including LabVIEW Real-Time with a multifunction data acquisition board and LabVIEW FPGA with an R-Series board.

How do I generate URL with multiple variables from input fields?
I'm creating an ad with four input text fields labels fname, lname, city and prov, and I wanted to know how to generate URLs based on information entered into the fields. The text fields default to display "First Name," "Last Name," "City" and "State," respectively, but if a user does not enter information in those fields, I want the URL to behave as if those were empty, if that makes sense. The text fields are in a movie clip called "input_text" and the button is labeled "send". If any of you can provide insight, I would be greatly appreciative. Thank you.
1. use if-statements to see if the text properties of your textfields meets your requirements for creating that url.
2. you can use the flash string methods and properties to create your url.
p.s. the plus sign + can be used to concatenate strings. -
How to create Base Dimensions with MaxL and Text File?
Hi,
Doing a scratch rebuild of a cube every month. Don't want to have a 'dummy' outline with base dimensions to copy over every build. Instead want to build from text file somehow. Thus my plan is to: 1) Delete the existing app/db 2) Create a new blank app/db 3) Create the base dimensions in the outline via text file and 4) Build entire outline via a text file. I'm stuck on #3 how to get the 'base dimensions' built via text file. I need:
ACCOUNTS
PERIOD
VALUE
VIEWS
SCENARIO
CUSTOM4
YEAR
CUSTOM3
CUSTOM2
ENTITY
CUSTOM1
I see this MaxL, but it uses a 'rules file' and I never have built a rules file to create base dims so I'm confused if it's possible or not...
import database sample.basic dimensions
from data_file '/data/calcdat.txt'
using rules_file '/data/rulesfile.rul'
on error append to '/logs/dimbuild.log';We rebuild our Departments and Organization from an enterprise hierarchy master each week.
The way we implemented (what you call #3) was to not do #1 and #2, but to have a "destructive" load rule for each of these dimensions using a text file. (in the "Dimension Build Settings" for the load rule, select "Remove Unspecified" to make it destructive)
The text file just has the dimension name (parent) and any children we needed defined in a parent/child relationship. For instance
"Sales Departments" "0100-All Departments"
This essentially works the same as deleting the app because the destructive load rules will drop all the blocks of data that were unspecified.
Then we run our SQL load rule to build the rest of the dimensions from the Location Master.
We perform a level-0 export prior to this process, then reload the level-0 data and execute all the consolidation scripts to get the data back (now in a current enterprise defined hierarchy) -
Numbers: How to create a spreadsheet with columns
I would appreciate help with something which seems quite basic, but I cannot figure it out from the manual. I need to track invoices. I would like columns with invoice number, supplier`s name, dates, and then of course numbers. I cannot see how to change a column (in blank spreadsheet) labelled as `A` to `invoice number`, for example. I am truly in the wilderness when it comes to spreadsheets! Thank you.
vista4444,
Welcome to Numbers. Spreadsheets (or "tables" as they are refered to in Numbers) will always show columns headed A, B, C, etc. What you want to do is type your labels in the first row (header row) under those letters. Similarly, the A column is a header column for the rows. These headers have a special function: they are used to name rows and columns and cannot contain formulas. If using formulas in other cells, columns can be identified by either letter or name in the header below. The same is true for rows.
You will know when the these headers are active when you see them shaded over near the far right of the format bar under the media icon.

How to integrate old formula with new as needed?
I have a report which displays /processes rows based on the 'Product Family' which we have as a 3 char code.
stringVar first3 ;
first3 := Mid ({REFERRF.RFDTA},1,3);
if isnumeric(first3) then
Mid ({REFERRF.RFDTA},4,30)
else
Mid ({REFERRF.RFDTA},1,30)
However, the current report makes it's own grouping which the user wants to keep. he does want the new groups that I can get from that table as well. how do I integrate this formula?
also new ones are custom and need to be separate from retail. so need to process this old way first. then not process these groups again (TRR, TRC etc) when processing by getting from table.
SELECT {Command.PROD_FAMILY}
CASE "TRR","TRC","TRP":
"Trophies"
CASE "PLQ":
"Plaques"
CASE "SGL", "TGL":
"Crystals"
CASE "MDL":
"Medals, 2 in."
CASE "MDM":
"Medals, Insert"
CASE "PIN","PNI":
"Pins"
CASE "CAC":
"Acrylics"
default:
"UNDEFINED: " & {Command.PROD_FAMILY};
so when my table has "CAC" I need the display heading to read 'ACRYLICS' in my logic i am getting the description from the same table but he doesn't want that for the above, only for any others.
the report looks like this> so u see for CAC they want it displayed as ACRYLICS. If I keep the current logic when i read the table i have to not read for CAC. or do this some other way.

182,458.95Hi,
The standard behaviour is that new instances of the process will use the most recent version of the process that has been deployed to the database. This allows you to deploy new versions of the processes without impacting on processes which are already in progress.
When the workflow engine determines what activity to run next in the process, the engine checks what the start date of the process instance was, so that it can check what version of the process was active at that time. If you update the start date for each running process, so that it reflects the date that you saved the most recent version of the flow, then the workflow engine will use the latest version instead of the version that it was running.
This is not supported. I would never suggest that you do this in a production environment - it does not make sense to be making frequent changes to the process in a production environment, since there is no supported mechanism for forcing existing flows to use the new definition. The engine is designed specifically to run the same version of the process for the duration of the process instance - what you want to do is to blow this out of the water completely. If you do change this, then all timing that is recorded against the activities becomes useless, and the other impact on the workflow process us something that you would need to consider incredibly carefully before deciding whether you want to take the risk.
HTH,
Matt

How to create tree table with column headers
hi,
when i drag and drop a view object onto my .jspx page as a af: tree table ,
am not able to get the column header of each column. all the columns in the table are just clubbed together not separated as in af:table.
can anyone say how the column headers are created for the columns when we drop a view object as a tree table?Hi,
this is not an option with the treeTable as it gets rendered by default when dragging and dropping the collection to the page. I haven't tried it, but I think you will have to check which node is getting rendered and based on this information add your own row layout . Sounds like a bit of coding work

How to do a JList with Columns???
Hi... I'm trying to do a Zip compressor in Java... I don't know how, but i want to do it...
But this is not my problem.... yet...
I want to put the selected files (files to Zip) in a JList Object... but I want to show the FileName, the Size, the Date and the FilePath...
For this I need to create Columns in my JList, but I don't know how I can do it...
Please help me... or sugest some similar...

How to override generated WSDL with existing WSDL file?
Hi there,
I am migrating our weblogic 8.1 web services to weblogic 10.1. As documented it is not possible to start implementing the web services from WSDL if the web services are based on XML Beans. Therefore I started from scratch, using an XML Beans Utility project and a web service started from Java. This works fine.
I now have a web service with a generated WSDL file, but there are slight differences with the existing WSDL file.
Is it possible to stop generating the WSDL file and just point to the existing WSDL files?
I already tried to expose the WSDL and change the WSDL location but it still returns the generated WSDL instead of the WSDL file that I want.
Thanks in advance,

SQL Developer: How do I copy data with Column Headers from the output grid?
Hello,
I am using Version 2.1.1.64.
I run a SQL query, I get the results grid in the "Query Result" window down below. Say I get 10 rows returned, with 5 columns.
I want to Copy this entire grid, plus the column headers/names, to the clipboard. So I can paste it under the original query to document the results of that query.
I can't find any way to do this. I can copy/paste the results grid, but it doesn't copy the headers.
The only way I see to do it is to go through numerous steps to Export to a TXT file, then paste that. Unfortunately, that is a lot of wasted steps if I need to do this over and over, plus, the output gets pasted in an ugly format with double quotes, etc.
It seems like the simplest functionality is to copy/paste the entire results grid, and of course you might the headers. Why is this so complicated/impossible to do?
(I believe Toad has the same problem. DBArtisan allows you to copy/paste the entire results, plus headers, though.)
Any assistance would be appreciated!
Thanks,
JohnAh, ok...
I had tried that before, and it didn't work, it seemed to copy the path of filename I was using. But I think that was because I had clicked on a Column Header first, and it had asked me if I wanted to filter. I think then it lost track that it was in the grid. It's a little flukey.
What I did now was to click on an individual cell in the output, then hit CTRL-A to select all, then hit SHIFT-CTRL-C. That gives me exactly what I want.
Thanks very much for your quick solution, I appreciate it!

How can I generate tones with usb 6008 using analog out?... tia sal2
Greetings All
I've been looking at the example Sim Phone.vi that comes with labview and would like to generate similar tones out of our usb 6008 device. I can get a very faint sound out of our usb 6008 using the example Gen Multi Volt Updates-SW Timed.vi Does anyone know the best way to alter Sim Phone.vi to have the sound come out of the Analog output of our usb 6008 device. ( I have a small speaker connected to the Analog out on our USB 6008)
PS: we are using labview 7.1
Does anyone know the Analog output frequency range of the usb-6008? Is this possible?
TIA

Gen Mult Volt Updates-SW Timed.vi 78 KBHi sal2,
As stated earlier you could most certainly use the USB device to generate sound, but that would be at a max update rate of 150 Hz. While according to Nyquist theorem you could get frequency information for signals below 75 Hz, you may notice that the quality of the data in that spectrum to be very low due to having so few samples.
While technically possible to produce you really should look for a device with a faster Analog Output update rate. I would look for a device that supports Analog Output at least 10x the maximum frequency that you want the user to hear. Some great, yet lower cost products, would be the M-Series line of products. They would give you the performance that is really needed in the type of application that you are talking about.
If you still want to use the USB Device, then you would need to use code similar to that found in the example Gen Mult Volt Updates-SW Timed (Found here: C:\Program Files\National Instruments\LabVIEW 7.1\examples\daqmxbase\Dynamic\ao).
Best of luck getting your system together,
