Formulas of the spreadsheet - data entry

APEX 4.2.1

When you try to duplicate a typical app focused on the worksheet, the data generally fall into 2 categories:-l' entry user and formula (VLOOKUP, cells A1 + B1 = C1, etc.) generated. In a report/list, there are a few options to display the columns calculated virtual a) 11 g or b) views containing the formulas as SQL expression as columns.

On a form page, if I want to show the computed fields as display only the page elements that are dynamically updated with the corresponding entry fields, one would use APEX dynamic action (change, set the value, etc.).

However, this means that the code for the "formulas" is duplicated in the table/view definition and DA Apex leading to maintenance problems when a formula must change.

Is it possible not to duplicate the code/expression formula and make available both the DA and the report?

Thank you

No would you put your formula in a package function, then when querying data by using a view - the function is used. and when the Calc display on the fly using the DA, the function by an action of pl/sql?

  • Hunting of edit mode in the IPTC data entry

    I had a problem where I am being chased the editing mode when entering data in an IPTC field.  The result is the next key I type is interpreted as a shortcut and put me in the mode to develop, or another view.  I thought at first that was botched, editing on my part.  But I was very attentive to my typing and I rejected this idea.  Has anyone else had similar problems?  This gets really annoying... It happens VERY often now.

    Gary

    Another common reason is when you edit metadata for more than one picture at a time. LR becomes extremely sensitive and it's so easy exit a field edit mode. Then, as you have seen, your next keystrokes are interpreted as shortcuts with unpredictable consequences.

    I found that it's easier to edit metadata about a picture and then propagate changes in other tables or by performing a synchronization of metadata using the LR feature remembers the last few entries for each field.

    In the second case, you can enter the title (for example) for a photo. Then select other photos you want to have the same title. Type the first character. LR offers to fill in the field with the last value entered. Accept that and you're done.

    I used ACDSee Pro in the past. She did not allow users to update the metadata fields for more than one image with the direct help of edition. You had to use their equivalent of the synchronization metadata. Adobe tries to be helpful by allowing you to update a number of selected photos using the metadata Panel. But since it doesn't have a 'Validate' button must decide when you have finished typing and do all the updates of the database. He doesn't seem to get it right always, but a perfect score for trying.

  • Multiple queries on the same data entry form

    I hope I am in the right forum!

    I'm working on a data entry screen that is interfaced with a data base for pre-determined entries.  The user will choose the first name of the Member, not problem here, then using this last name, a list of names that match the last name.  Here's what I have so far:

    < CFQUERY DATASOURCE = "cfissues" Name = "LNameQry" >

    SELECT LastName

    Members

    ORDER BY name

    < / CFQUERY

    < CFQUERY DATASOURCE = "cfissues" Name = "FNameQry" >

    SELECT FirstName

    Members

    WHERE LastName = #LastName # (' #LastName # ') (#FORM. LastName #)

    < / CFQUERY

    <!--- ================== --->

    < CFSELECT NAME = 'name '.

    QUERY = "LNameQry."

    VALUE = 'value '.

    etc.

    < / CFSELECT >

    The user selects a member of family name.  Using this name, I want to run the FNameQry query that retrieves all the names that correspond to this last name chosen by the CFSELECT statement.  In this way, the drop-down list for the first name field contains only the names of skills (not all 7,000 on the database!).  I have more to do beyond that, but just to get this first part of work would be of great achievements.

    I have used various combinations of the name chosen by the CFSELECT run FNameQry, but nothing seems to work.  I get an error on LASTNAME is not defined.

    I guess I need to (somehow) define a variable that will be filled with the value selected in the CFSELECT statement and use it in the FNameQry?

    Hello

    Use isdefined "(form. LastName") for FNameQry

  • Move the cursor to data entry in the first element of array

    It seems that it should be simple, and that I still can't find a way to do this.

    I want to have a dialogue VI with a single Berry. When loading of the dialog, I want the data entry cursor to appear in the first element of the array, so the user can begin to enter data with the keyboard and I can't click on it with the mouse and then tab on the rest of the table. The property node 'Key Focus' just seems to give me a box around the entire table without any cursor active data entry.

    A table control has a property called array element. Get a reference to it and its main objective set to true. I just spent a few minutes test this and it didn't work for me if I first got the reference, then turn the key a second property node, rather than doing everything in one implicit property node. In addition, it still affects the update to the second element of the array, which is certainly not too useful. I have not found a way around that in my brief tests, unfortunately.

  • Data entry on the host VI without FIFO Massive?

    Hi guys,.

    First post on the boards and about two weeks in LV in time real/FPGA so be gentle!

    I'm data capture of a system using a CRio 9082 and Converter A/D NI9215. The FPGA vi runs a timed loop (10 US or 100kS/s) that pulls in the data and sends them to a target-to-Host DMA FIFO (4096 long, single precision). Since I want to synchronize data for a TTL output, the FPGA also sends a True/False value through a port DIO (NI9402). So, for example, if I want a TTL of 100 Hz pulse and time of the loop is 10 US, then a complete cycle of TTL will last 1000 loops with the half cycle lasts 500 loops. Both the position in the LIFE cycle (0-1000) and the acquired data to that position in the cycle are intertwined in the FIFO. I have attached a picture of the VI.

    The host vi simply reads the values of the FIFO, decimating the interlaced output and stores the data in a table for later processing. I have also attached a picture of the host vi. The problem is that the data acquisition time could be as high as 10 seconds, which would mean that the FIFO host-side would be long 2 million items!

    SO my question is how to change the host vi so that rather than wait as the FIFO side host to be filled, its size can be reduced and yet not lose data points in the table fill? One can rightly wonder why I did things like that, but I found that fill a massive FIFO ensures that I do not lose the continuous position TTL data, but then I thought it was totally ineffective and some sage advice is necessary!

    Thank you!!

    My advice would be to do the following:

    (1) configure FIFO depth to be quite large not to overflow during a regular operation, but don't try to configure it to keep your entire dataset in a single shot.

    (2) If you send only the integers to the FIFO, do not configure it for double rooms.

    (3) instead of voting for a whole dataset, you can read the smaller packets of the target and build them together on the host. Pop, a delay in your in a loop to read each 10/100 ms, 0 items via a FIFO Read, out of the remaining elements of wireless node to the number of items in a FIFO read node entry. It will take all that is in the FIFO at this stage. Using a registry to offset, concatenate the table with table of the previous iteration and stop all loop when the length of the array reaches the number wanted items.

    You might need to play to ensure that the order of the data in the FIFO is not flipped depending on when you start and stop acquisition, but at least it's a start.

  • How to remove header, time and date of the Subvi "export waveforms to the spreadsheet file?

  • Open the spreadsheet at the request and add data

    Using a cDAQ 9172 and Labview 8.2, I collect four channels of noisy pressure and temperature data collected during a product test.  The data are shown live on the band on the front panel cards after be smoothed by the average feature of the sample Compression Express vi.  All this works pretty well.

    Data are presented to the test operator so that he can see when the test conditions have stabilized, which usually takes 3 to 5 minutes.  After stabilization, I want to be able to press a button on the front panel so that a spreadsheet is open (ideally, with the original opening time as part of the file name) and a scan of the four data channels are added to the spreadsheet (with a timestamp).  Then, ongoing test for 1 or 2 minutes, I want to again push the button every 10 or 15 seconds or so to add more data analysis, so that we can see later that the conditions had really stabilized.  The exact date and the number of analyses of additional data is not critical, I just want to be able to connect to another 4 to 8 lines of data before you complete the test.

    I have a kind of sort of do this, shown on the seal 'on demand spreadsheet.vi' below.  Noisy signals are shown here numbers just under the random name embedded in a table (which is how my data writing to a spreadsheet file in my actual program).  The problem with this arrangement is that the spreadsheet file is created each time that I start the vi and there are several times during execution of tests and data are not collected for some reason any.  Accordingly, we would end up with a large number of files with no or data without meaning .xls.  I just want to create the worksheet file when I press the button (s) during a successful test after conditions have stabilized.

    I tried a slightly different approach in the joint 'on demand spreadsheet 2.vi' below where I added a switch to toggle to activate a case to open the spreadsheet, and an additional button to save data.  It seems like it should work, but I don't get all the lines of data, only the headers.

    I'm still pretty new to all this and I have spent days trying to figure this out.  Any help is greatly appreciated.

    I don't have 8.2.  You can either save my vi and publish it on the thread Downconvert VI ask, or you could look at just the image:
