How to perform a calculation only if a field is empty
I have the following script to generate a random 4-digit invoice number.
this.getField("INVOICE_No").value = Math.floor (1000 + Math.Random () * 9000);
It works fine, but if I hit the action button several times he continues to change the invoice number.
Is there a way for her to run the script only if the field is empty?
Yes, you just add something like:
var f = getField ("BILL No.");
If (! f.valueAsString) {}
f.Value = Math.floor (1000 + Math.Random () * 9000);
}

Show LOV only when the field is empty
Hi all
My surroundings:
Oracle 10g on Windows
Forms [32 bit] Version 9.0.4.1.0 (Production)
Oracle Database 10 g Enterprise Edition Release 10.2.0.5.0 - 64 bit Production
With partitioning, OLAP, Data Mining and Real Application Testing options
Oracle Toolkit Version 9.0.4.1.0 (Production)
PL/SQL Version 9.0.1.5.1 (Production)
My problem:
I have a field in a block, which is text_item and is linked to an element of LOV. I want the LOV appears automatically, whenever I tab in there, only when the element is EMPTY (for example when I try to insert in the block). When, upon request, it should show only the value in the field, and user can choose to activate the LOV, by pressing F9, if she wants to. It now displays automatically each time text agenda is a debate (works very well when the user is inserted, but annoying when she questioned the shape and trying to tab thru.) Every time she focuses on the field, LOV is popping up!)
The current setting for the property on the element of text field: Type: text element
The list of values: MY_LOV_NAME
Validation of list: Yes
Properties on MY_LOV_NAME
Auto display: Yes
Any suggestions? Or trigger level I can use, and if so, what build_in can use?
New forms and will greatly appreciate advice from pros!
Thank you
Libran_girlIt's very simple,
IN once - new - item - Instance
DECLARE
V_LOV BOOLEAN;
BEGIN
IF: NOM_ELEMENT IS NULL
THEN
V_LOV = SHOW_LOV (LOV_NAME);
END IF;
END;Try it, you will get your result, if it doesn't work, try: block_name.item_name

How to get the value of the textInput component to perform the calculation?
I need some help here... I'm trying to get the value from the user input to the TextInput component that is the age, size and weight to calculate the bmr and display the result in member("result").text.
How am I suppose to pass the integer in order for me to perform the calculation? If you'd be grateful if someone can help me with this, thanks!
Here's the formula:
The equation of Harris Benedict BMR estimates:
For women: (9.56 x w) + (1.85 x h) - (4.68 x a) + 655
For men: (13.75 x w) + (5 x h) - (6.76 x a) + 66
My mistake. You can only re-branded a string to the text property of a text member. Just need to convert the value to a string using the string function. Use this
Member ("result"). Text = string ((13.75 * value (member("weightText").text)) + (5 * value (member("heightText").text))-(6.76 * value (member("ageText").text)) + 66)

How to calculate if and only if the number is higher?
I need to perform a calculation where the box has will multiplied by box B if and only if the number of entries in box A is greater than or equal to 5000.00. How to complete this calculation? Thank you.
OK, in this case you can use this code as the calculation script custom of 'Area C':
var a = Number(this.getField("Box A").value); var b = Number(this.getField("Box B").value); if (a>=5000) event.value = a*b; else event.value = 0;

How to restore the calculator application to drag it to the top of the screen to control
Can how I restore the calculator to drag it to the top of the screen to control center? It seems to have been removed from the bottom row? Thank you
Are - what you got to remove the calculator of your applications on the phone? You can find the calculator on the phone itself? If you find it, then try a reset. Hold down the home and sleep/wake together until you see the Apple logo and then release. The phone will restart. There are no settings to change what appears on the display. See if the reset solves your problem.
EDIT: what exactly you see in the Control Center? If you see only controls the music, then drag to the right to see the rest of the access to the control center.

How do I run a script only if the field is not empty
How do I run a script only if the field is not empty
Well well, thanks to you, I had a full date on separate days, the months and the years in different areas. But now, I have a problem, as PDF has several fields calculated with script if you enter the date calculated by all other areas, which have separated and undefinied gives me does not want to put this to not always use this field. I tried to put one conditional if else but I sale. Esto, this is what I'm wearing
var datesol = event.value;//declaramos the variable
If (datesol = "") {}
this.getField('yearsol').value = "";
this.getField('monthsol').value = "";
this.getField('daysol').value = ""}
else {}
var array_datesol = datesol.split("/"); / / separamos esa con date the split funcio
this.getField('yearsol').value = array_datesol [2];
this.getField('monthsol').value = array_datesol [1];
this.getField('daysol').value = array_datesol [0];
With what they do not separate them now.
Help please
As mentioned, you cannot use
If (datesol = "")
because that sets the value of datesol to «» (you will need to double for the comparison operator =)
If you want to run code only if it is NOT empty, while it takes:
If (datesol <> "")

How to send a pulse only to analog output
I send a function rect through to the ao, thorugh the transmitter transducer, then a receiving transducer through AI. Although I'm kind of a signal, I can see that there is something wrong. What I think is happening, is that the pulse is transmitted continuously while I want it to be sent once. of the received signal, waiting for the signal to reach 0.2/1500 s as the medium is 0.2 m in diameter and the speed of the sound probagation through it is around 1500 m/s. So, with these considerations, I have the following questions:
1. How can I configure the wizard daq output to send only 1 rect function
2. read permanently or for a period of time
I have attached the output and input along with a photo of my VI signals
Thank you
Hi Macane,
For a unique configuration of generation/acquisition, you would set your DAQ Assistant to finish instead of continuous and calculate how many samples is your only impulse you send. For the acquisition, you can configure a finite acquisition of trigger reference analog where it will begin to capture after your signal is received, or if you do not want a triggered acquisition, you can set the number of samples to acquire. For example, finished task sampled at 1 kHz to 2000 samples would correspond to a second acquisition 2.
You can configure all the wizards within the express VI data acquisition by double-clicking the VI. I hope all goes well!

How to perform deconvolution using FFT
Hello everyone
Is there anyone who knows the algorith or can give me a vi that shows how to perform deconvolution of the two functions by using the FFT. Using labview for deconvolution, the suggested algorith is.
- Calculate the Fourier transform of the input sequence X * Y.
- Calculate the Fourier transform of the input sequence Y.
- Divide the Fourier transform of X * Y by the Fourier transform of is. Call the new h sequence.
- Calculate the inverse of Fourier of h to get the deconvolved Xsequence.
I tried to do e same but did not work. I enclose a Vi in first, I bypassed a pulse-to-pulse-triangular square. Then I deconvolutee the convoluted signal using a triangular pulse with deconvolution tool in labview. Then, I tried to do the deconvoltion using the FFT algorith but did not work. Y at - it someone who has an idea on how to perform deconvolution using FFT.

How to remove vista so only 7 is running
my child has just installed win 7 but has not removed from Windows vista, how to remove vista so only 7 is running?
Original title: my child has just installed win 7 but has not removed from Windows vista, how to remove vista so only 7 is running?
Hi Tarf,
· Are the two copies of Windows 7 and Windows Vista installed on the partition, or on a different partition?
· At the start of Windows 7 or Windows Vista, you receive two Windows startup options?
· Are you able to boot to Windows 7 and Windows Vista installed on the computer?
You can check the following information on your computer and post back the result to help us analyze the problem and remove a copy of Windows Vista.
Start Windows 7 and Windows Vista installed on the computer and access the computer and check the partitions in Windows to make a note where Windows 7 and Windows Vista are installed and after return of information.
If you are able to make a note of the partition on which Windows Vista is installed, and if you are confident about it, you can start on Windows 7 and check on which Windows Vista is installed; make a backup of data in Windows Vista and later you can remove folders of Windows files, users and the program or format the partition.
I hope this helps. Let us know the results.
Thank you and best regards,
