How do I convert a group summary average from seconds to DD:HH:MM:SS
I am new to Crystal Report XI. I have a column with seconds as values. I grouped the column to get an average seconds value per group. How do I convert the grouped average seconds to DD:HH:MM:SS?
Thanks,
Mike
Hi Mike,
Here's a formula from Ken Hamady's website:
NumberVar TotalSec := {YourTable.TotalSeconds};
NumberVar Days := Truncate (TotalSec / 86400);
NumberVar Hours := Truncate (Remainder ( TotalSec , 86400) / 3600) ;
NumberVar Minutes := Truncate (Remainder ( TotalSec , 3600) / 60) ;
NumberVar Seconds := Remainder (TotalSec , 60) ;
Totext ( Days , '##' ) + ':' +
Totext ( Hours , '00' ) + ':' +
Totext ( Minutes , '00' ) + ':' +
Totext ( Seconds , '00' )

The D750 isn't yet supported. It may be a few weeks before Adobe provides an update for the latest versions of Photoshop/Elements. Maybe October/November.
They usually provide a pre-release version a few weeks beforehand (any day now, hopefully), but AFAIK they don't usually work on Photoshop Elements. -
How can I convert output data (string?) from GPIB-read to an 1D array?
Hello all,
I am reading a displayed waveform from my Tektronix Oscilloscope (TDS3032) via the GPIB Read VI. The format of the waveform data is: positive integer data-point representation with the most significant byte transferred first (2 bytes per data point).
The output data of GPIB-Read looks like a string(?) where the integer numbers and a sign like the euro-currency sign are seperated by spaces e.g. #5200004C3 4 4 4 4 3C3C3........ (C represents the euro-currency sign).
How can I convert this waveform data into a 1D/2D array of real double floatingpoint numbers (DBL) so I can handle the waveform data for data-analysis?
It would be very nice if someone know the solution for this.

hanksHi,
First of all, I'm assuming you are using LabVIEW.
The first you need to do is parse the string returned by the instrument. In this case you need to search for the known symbols in the string (like the euro sign) and chop the string to get the numeric strings. Here are some examples on parsing from www.ni.com:
Keyword Search: parsing
Once you parse the numeric strings you can use the "String/number conversion VIs" in the String pallette.
Hope this helps.

How do I create a Group email list from my contacts??
I can't figure out how to create a Group email list from my contacts on my iPhone??
I thought that was how I did it before ( a year ago ) but the group is created in my Email software but the group won't synch to my phone?! However it will synch randomly - i.e. singular new emails synch from my phone to my computer, but I am not noticing the computer transferring data to my phone...same with calendar...hmmm, maybe that's the problem - issue synching anything entered into my computer first...anyone hear of this? It seems that this started about a month ago, I had to restore my phone and it would not restore with the most recent backup, so I had to go back a couple of back ups... since it has been glitchy! HELP!

How Do I convert to adobe for application from email attached
How do I convert to PDF file to type the application form .
Hi khin Thu,
Do I understand correctly that you have a form that you want to convert to PDF? You can use Adobe Fill & Sign to upload and fill out for your form. See Tutorial: Introduction to Adobe Fill & Sign for more information.
Please let us know if you have additional questions.

How can I convert a poorly exported project from 6.* to 7.0?
I made a critical mistake some years ago. I used the advanced
features of the save option to write out my project with all the
sub-vi's and libraries. Now I have a version 7 LabView I am
attempting to convert it. The trouble is that many of the
features that I use in the project (serial I/O, equation parsing, card
initialization) are part of the distribution. The real nub hit
when I tried to replace the locally defined equation parsing vi with
the one defined in the system. The system vi would not run bcause
the underliing function exists inside the lvanlys.lib stored locally,
which does not convert.
How can I extricate all the parts of my considerably complex vi that
are my creation from the bits that should be part of LabView?Hello,
There is an example program on the NI website that is supposed to help with this situation. Here is the URL:
http://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=B45EACE3E38856A4E034080020E74861

How does one create a GROUP mailing list from an e-mail message ? ?
I am having no end of frustration trying to figure out - using the latest versions of Apple Mail and Apple Address book in side-by-side windows, t he following:
How to select; then 'drag & drop' a list of email addresses from an incoming email message I am reading, so that I can create in my own address book a duplicate "Group" list bearing all the addresses that got the message.
I am sure I have been able in the past to use simple drag-n-drop technique between the mail window and the newly created "Group" window in Address Book, but it won't work this time .
Is there a script or a third party app somewhere that will lift addresses out of the "TO" and "c.c." fields in an Apple Mail message and import them into a designated (new) 'Group' list in Address Book.
Or is there a way to create a CSV file from an email message - if that will do the trick ?Mailscript's Add Addresses script should open a window with all the addresses in the email listed. You can select the ones you want to import, you can choose the group or create a new one, and you can pick the label for the email address. It will stay open so that you can add different emails to different groups.
Your description doesn't sound anything like Mail Scripts. -

How do I convert this Applet to launch from a JFrame instead??
A simple program where the user can sketch curves and shapes in a
variety of colors on a variety of background colors. The user selects
a drawing color form a pop-up menu at the top of the
applet. If the user clicks "Set Background", the background
color is set to the current drawing color and the drawing
area is filled with that color. If the user clicks "Clear",
the drawing area is just filled with the current background color.
The user selects the shape to draw from another pop-up menu at the
top of the applet. The user can draw free-hand curves, straight
lines, and one of six different types of shapes.
The user's drawing is saved in an off-screen image, which is
used to refresh the screen when repainting. The picture is
lost if the applet changes size, however.

How can I convert my company's logo from PSD to Vector?
We need to submit our company logo for an event we are sponsoring and they have asked for it in vector, but it was created in Photoshop. Each time I go to convert it following on line tutorials, I only get the outline and am struggling to recreate the formatting in illustrator. Does anyone know of an easier way to do this that at least would make it easier for me to recreate the formatting?
Reset the type in Illustrator, draw the swooshes. Should only take a few minutes. The font, for anyone wanting to play along, is Google's Philosopher...at least that's the version I have.

How do I convert more than the menus from 16:9 to 4:3?
I'm trying to make two versions of a wedding movie, one for widescreen users and one for oldsters with pre-HD television sets in the 4:3 aspect ratio.
After successfully burning many copies at the 16:9 ratio, iDVD allowed me to convert my theme to 4:3, but not the underlying video/slideshow. Is there a way to convert it all? My titles and captions are all embedded in the video and are not centered, which means standard TV users will not be able to read them.
Thanks,
MikeMy titles and captions are all embedded in the video and are not centered, which means standard TV users will not be able to read them.
Why ever not? Presumably when thay watch a commercial DVD it shows as 16:9 across the centre of their screen, whereas on a more modern widescreen TV it fills the screen?
Your DVD will work the same way.

Why are signatures from .HTML files no longer appended (v31.1.0)?
