How can I make a query by date with several TDMS files?

Hi,
I have a project that can write and read TDMS files everyday (a file for each day with date and time). There, I can import those files to excel (I choose a file and load it). But, I have a question: How can I make a query by date with those TDMS files? I'd like make a time stamp for start date and stop date, where I could compare the TDMS file dates and sum the values that are in the channels where these files are similar. For example, I save a file with "02/01/2013" name, in other day "03/01/2013", in other day "04/01/2013"... so, i'd like put in time stamp for start date "02/01/2013" file and to stop date "04/01/2013" file, than, sum all values that range with my TDMS files existing. How can I make that?
Thanks all,
Val

Hello Val_Auto.
You're Brazilian, no? Me too. = ^ - ^ =
I converted VI to version of your LabVIEW (8.5). Is attached in this reply.
This VI search all your TDMS in a range of dates and join them in a single TDMS. I hope this is what you wanted.
Query TDMS is the main VI. The TDMS VI Search changes the date format that out from calendar control (which is DD / MM / YYYY) to DD-MM-YYYY. This is because you can't name files using "/". I chose "-" but, if necessary, you should change to keep the same format of your TDMS files.
If you have any doubt as to its operation or how to make changes to adapt VI for your application, keep at your disposal.
Thank you for your contact; I hope have helped you and succeed in your application.

In my report I have to get these record typpes as field name dynamically whichever is available in that lookup and record values against them.
its a BI Publisher report.

How can I make a graphic (scatter chart) with 1 "y", but multiple "x" (to make a multiple linear regression)?

how can I make a graphic (scatter chart) with 1 "y", but multiple "x" (to make a multiple linear regression)?

Émilie,
The default for X-Y Charts is for X values not to be shared, so it's entirely possible for you to create X-Y pair sets that have common Y-values and independent X-values.
This answer assumes, as always, that I properly interpreted your problem statement. A linear fit line for each pair set should satisfy.

How can I make Aperture share on Flickr with sRGB?

Since I upgraded to 3.3, all photos I share on Flickr have an embedded Adobe RGB profile. Changing Web Export presets has no effect; neither does any other setting I can find. How can I make Aperture share the images with sRGB instead of Adobe RGB?

If it is possible you do it by changing the print product country in the iPhoto preferences

HT204053 I just changed my apple ID, how can I make my icloud link up with my new ID?

I just changed my apple ID, how can I make my icloud link up with my new ID?

Did you simply change the primary email address of your existing AppleID at
https://appleid.apple.com/
Or, did you create a new AppleID. If you created a new AppleID, then you cannot. All you can do is use the iCloud with the old AppleID, or create a new iCloud account with the new AppleID.
If you changed the primary email address of the exisitng AppleID, you may need to uninstall the iCloud account on the iPhone and reinstall it to get it to use the new email address and password (you won't loose anything, its just there a means of resetting the cached credentials associated with the iCloud account).

How can I burn a disk of photos with a modified file name?

After importing photos from scan device, I use Photos > Batch > Change to rename files. When burning a disk the changed file names do not transfer with the image but use the original file name. How can I burn a disk of photos with the modified file name?
This is what I have done so far with no success.
Drag selected photos from Event to Burn Folder where the file names were changed. Burn folder lists file with original file name.
Drag albums to Burn Folder with the same result.
In Filer I am able to change the iPhoto Library > Master > Date > Filename and then drag to burn disk folder and see the changed name but this is a single file exercise without a view of the file's image, but to use the new file name in iPhoto events I have to repeat the naming convention.

File > Export.
In the resulting dialogue note the "Name" section. Choose to use the Title as Filename.

Hi, how can I make titles with coloured schadows in premiere elements????????

What version of Premiere Elements are you using and on what computer operating system is it running?
Are you looking for text whose fill is a 4- color gradient instead of a solid color. Or something else, like text whose fill is a still or video?
Answers are in the details. So, please, more details so I can fine tune a reply to your question.
Thank you.

How can i make my iphone 4 compatible with other itunes?

I put music on my phone using my computer and then try it with my friend's computer. It works fine everything goes well, but when i try using my computer again it makes me delete all of my music! how can i make it work with both itunes without deleting all of my music and having to start all over again??? H E L P PLEASE!

My thought exactly. I would like to know why Apple designed it this way. I think you should be able to manage your files on any computer with any product. This has been my biggest gripe about Apple. If I have a song or photo on my desktop computer and want it on my iphone great. I should also be able to take that song or photo from my iphone and put it on my laptop at work. Hmmmm.
