Reliability of the data in the conversion to & from a Variant...

It is possible to convert any data type to a variant, and then turn it back on.  In doing so, are there data types who will lose information during the conversion process?  If so, why?

Yes, you can convert any type to a variable ranging and back. There is a VI called "Variant data" which will have a type as input. He continued to convert the variant the correct data. The side variant must know what type of data to expect. He can pull of the Variant. However, you can use a cluster of generic data that consists of a username and a Variant. Then you can have different types of data which can handle the side reception. It is a two-step process. One of conversion the variant of general type (data type and Variant cluster). The second would be a case statement uses the type then covert the internal variant to the specified type. This approach is used for generic messaging systems. The upper levels of the code will know what to do with the data. The lower levels are just generic data passing around.

I'm not aware of any information that get lost during the conversion of the data to and from a variant. Of course, I not had no problem using them.

  • Style is lost in the conversion RH8 from an older version

  • Optimize the conversion of SGL data chain

    As the title indicates, I'm looking to pronounce on a more efficient way (as appropriate) to convert a string into an array of SGL.

    The detachment is just to get feedback on the best ways of doing things from a personal educational point of view. I don't actually have to improve performance... (Just keep improving my skills of codeing.)

    'More effective' here must take to be less cycles of CPU and low memory footprint, in that order. (That is, most small load on CPU is preferred, if smaller memory footprint is at the expense of the other cycles CPU, the hit on memory footprint is preferred).

    The length of the input string comes from a TCP read and contains only the raw bytes of the expected (in this case, SGL) format without any header/footer of meta-data.

    Currently, my implementation is very simple and given that the expected table size is known, I am relying on the loop being smart in his automatic indexation allowance.

    For the conversion, I do a right type-Gallery of 4 characters at once.

    The code below, the for loop is simply intended to give a 'real' output boolean if the string length is the length of expected as determined by the input string 'number of track points. No additional error handling is required or necessary.

    I suspect the "subset of string" combined with the iterations (for loop) are the two worst performance in this VI hits, but I can't think of a good way to do the conversion as a table, and if I could, then I should at least do a conversion in 'string to array U8' first.

    Thanks to all who took the time to read and watch. Your time and your contribution is appreciated as always!

  • problem about dynamic data to the conversion of table 1 d

    Hi all

    I have problem with the conversion between dynamic data and table 1 d.

    I wrote a simple VI to show the problem, as the attached picture. Convert dynamic data in table 1 d, and then return to the dynamics of data, I use 3 tables of waveform display data in 3 different places, but only 'force contact 2' the graph looks normal and the 2 other cards are strange data shows. In addition, the probe indicates that data are all just before going to the charts. What is wrong with him?

    Can someone help me?

    When you convert a table, you lose your calendar information.  You need to convert a waveform and manipulate waveform data.  Use a Structure of elements in Place with waveform components to manipulate waveform data.

    I joined Skype in 2009 from my old LAPTOP.

    I used Skype on laptop computer for all time.

    Today, I bought a new computer, I downloaded Skype and singed in.

    But I knew the history of the conversations did not save, and I want to see

    the story of my new computer, how can I do?

    Is there a way to copy the files of the conversation on my computer in the new Skype history?

    Thank you much, Noam.

  • To convert a new Win 8 PC Win XP PC w/Ffx 28.0, is Ffx 28,0 v. keep? If not, then v. and when and where to install the conversion?

    I will be the conversion of my PC for 9 years with the victory. A new PC with Win XP. 8. my list of program control panel tells me that my old PC running Firefox 28.0 (x 86 en - us). I need to be sure that Firefox 28.0 is your latest version and that I should go to my new PC (it seems to be so many versions out there that it is confusing... in one place you say version 17 is the only one to use). If I do not need to install another version of Firefox, I would need to know that one, and that it must be installed on the old computer first, before changing the PC, or anywhere elsewhere in the in the conversion sequence, that is, on the new PC before (or after?) transfer everything from the old PC. I intend to transfer to new PC software free LapLink offered for us the current XP users through a LapLink/Microsoft agreement.

    Yes, Firefox 28 is the current Windows XP or higher version.

    I'm not exactly sure how works of Laplink, but assuming that he transfer all your data from Windows user profile, then you should bring your Firefox to your new computer data. You can confirm by checking here on both computers and comparing what you see:

    (paste into start > run or WinButton + r): %APPDATA%\Mozilla\Firefox\

    In particular, make sure that Laplink copied the profiles.ini file and folder profile and its subfolders.

    I suggest you copy the data in the first, then installation of Firefox. In this case, when you install Firefox it should automatically find your data and you will be running. If you install Firefox first, then you will need to take some additional precautions to get your old data in.

  • 'image' for the conversion of "photo".

    LabVIEW dear gurus,.

    I have a problem I would like to help with. I have a labview VI that creates an image using the entire block 'IMAQ image', and I a VI which allows the selection of image with the mouse. Most of the code for this second VI is an example. The problem is my photo VI selection requires that the image of the data type 'image', but the photos my other VI creates are the data type "image." CTRL-h wrote the first type of wire is 'image' and the second type of thread is "Image Dst Out (IMAQImage). I need either to convert the 'image' to 'image', or rewrite my photo selection to take in a variable "image" instead of "photo". I'm not particularly good at labview, I'm short on time, so conversion seems to be the best option. I found another thread that talks about the conversion of an 'image' in a table, but I do not know how to turn this table back into a 'picture '. Someone at - it ideas?

    I have a strange problem here. I'll try to explain better. I work with APEX 4.2 and of Oracle Database 11 g Enterprise Edition Release 11.2.0.3.0 - 64 bit Production.

    Here are my parameters NLS_SESSION_PARAMETER and NLS_DATABASE_PARAMETER: NLS_NUMERIC_CHARACTERS,.


    I have a table with a lot of body numbers, and when I imported a MS Access application data, all fields were imported with the comma as decimal separator.


    Now, I have a form with several fields of number and when I leave a numeric field, a body of numbers of amount total is calculated and automatically filled with a bit of javascript.


    Now the problem: calculating fields (sum) succeeds only when I use the decimal as the delimiter. If I use the comma, I get a NaN value in the total amount field. I managed to convert all commas in points with javascript, so the total amount is calculated.

    When I try to save the record, I get the error: ORA-06502: PL/SQL: digital error: error in the conversion of char to number because I'm trying to save the separator point in my number fields.


    I tried to use REPLACE function to replace the. by one, before winning but does not solve the problem.

    OK, the problem is solved people.

    Somehow, the registration procedure had an influence on another calculation of my form and the error came from this process. So I put a to_number and replace stated in the calculation and all records very well and it shows my total.

  • Windows XP to be p2v. How to prepare for the conversion smooth?

  • I need some opinions on the conversion of doc and xls to pdf and jpg

    Hi all

    I'm working on a Java project (so all MS api or .net can not used) where we need to convert MS Office 2003 (first doc but also XLL if possible) files to pdf and jpg. Would be nice to convert txt as well as to fix the indexing research.

    Do you have previous experience in the conversion of doc (word files) to PDF?
    Searching the Internet I find a lot of links to this Web site dancrintea.ro/doc-to-pdf/, which apparently has a solution for all doc, xls, ppt.

    While waiting for a response on this solution, it would be useful that you can share your experience:
    -did you do in a Java project
    -What did you use and how it works

    Never the less important are the costs of the solution because we have to distribute my project to more customers.
    so I need something with a balance between costs and results - I want to say can not invest in an expensive solution for doc/xls to pdf format.

    Thank you for your sharing information.

    The answer to that is:
    It's hard. Very hard. There are few native Java solutions, your options are:

    (1) convince you the basic user who. Sucks DOC and RTF's The Way.
    2) Open Office script (or office). Open Office has an API that can do what you want
    (3) look at the alternative outside and everything, but as a general rule, they are reading rather than rendered data.

    Cool the OO API has even an example of file conversion.

  • On the conversion of the Member of BSO formula helps ASO

    Hello

    I'm new to MDX and got stuck on the conversion of function @IsMbr to ASO.

    Here's what my formula BSO

    Note: A, C, D and L are of different sizes.

    I am able to generate the formula of the BSO and I've tagged dynamic members top member. I have therefore been able to data aggregated.
    Formual to ASO works on lower-level members, but I can do together to ASO. She says all dynamics.

    Thanks for your suggestions.

    Hello

    There is a very good article in the MDX > Aggregate Storage topics > MDX contour forms Essbase technical reference which are necessary to carry out certain functions of BSO calculator examples of the MDX, the link to the 9.3.1 version is attached here.

    [http://download.oracle.com/docs/cd/E10530_01/doc/epm.931/html_esb_techref/techref.htm]

    The @ISMBR example is slightly more complicated than what you need, what it is looking for a range of members, where you don't need one Member, so it should work (which assumes that you calculate 'Member C'):

    IIF (is ([Dim]. CurrentMember, [A member]) AND IsUda ([account]. (CurrentMember, 'L'), [member], missing)

    Please note that when the words are underlined in what above, they must appear in [but here assumes that it is a link and notes.] This formula is perhaps not optimal but it works for me.

    I'm afraid that my MDX skills probably don't extend far enough to help with your other point, it sounds as if you need a the IIF formula that performs a calculation if at level 0 and children are current Member if, at a level higher than 0, but I think that could involve a lot of orders "Crossjoin" and I have not tried those of front.
