How about you, the personalization feature in reading a csv file?

I want to know about the personalization feature and how to implement it in j2me blackberry for reading a csv file

So guys someone help me about this

It is a code that I found somewhere that will provide this type of functionality.

It uses % and $ to indicate where substitutions must go, and the number between the two is used as the index in the array of strings that you provide as the second parameter.

I suspect that you can adapt it to your needs.

As Simon points out, it's really just a problem of standard Java, and you will be able to find solutions to these kinds of things looking around the Internet rather than here, where our attention is BlackBerry Java.    in fact, I think I found this code somewhere on the Net.

        private final static char LEFT_INDICATOR = '%';
        private final static char RIGHT_INDICATOR = '$';

    Hello

    Sorry, but you cannot use an internal hard drive for ReadyBoost. Indeed, an SSD can not use ReadyBoost.

    This feature can use a USB flash drive external as a hard drive cache to improve the disk read performance.

  • How "reverse you" the effects of the dynamics of transformation of fm records

    I found a box of tapes of audio recordings of the concert FM since the 1970s and 80s I want to capture and rework for my collection.

    How "reverse you" the effects of the dynamics of transformation of the fm recordings.

    Are there plugins at the hearing. Please tell us which one is best and he offered to help me get started.

    If this is not the case in hearing is there other software out there that would be good to use.

    Thank you

    Rick

    I fear for all purposes, you can't do that - it always makes things worse.

    The problem is that you have no idea of the time constants of compression or amounts used, and without this information, everything you do will bring another change to the dynamics, but won't cancel everything that happened before, because it will be the exact opposite. Processes such as Dolby, even if the amounts are specified, are equally difficult to decode simply because nobody never provided for in reference levels (except professional stuff, like Dolby A), therefore, generally, people simply don't and just swallow the BF a little depending on their ears.

    Even if they could have done (possibly at an advantage...), Dolby has never authorized anyone to produce a Dolby B reading filter and forbade indeed expressly probably because they know that it will do more damage that would prevent ever, just because of differences in level and the weird effects they may cause with an incorrect decoding.

    So I'm afraid that we cannot help you with this, other than to say 'let alone '. Even if you know what was the encoding process, then it will always be difficult to decode, simply because of the issue of levels.

  • How uncheck you the option buttons in Adobe Acrobat Pro XI?

    How uncheck you the option buttons in Adobe Acrobat Pro XI?

    OK, so I have a three sets of radio buttons each three choices, so, basically, it looks like this

    Cheques:          (    )          (     )          (     )

    Deposit slips: () ())

    Envelopes:        (    )          (     )          (     )

    In case anyone is confused, () are radio buttons. Basically, I want radio buttons to act as check boxes, I want to be able to click them and outside. I don't want us boxes because I want them to be circles and not square. Is there a way to do this? Maybe using javascript, what code would be?

    Radio button names: QTY.

    XQTY

    XPrice

    Thanks in advance guys

    You don't have to use a script. I rarely use the option button because they cannot normally be deselected once in the Group has been selected, but here's a backdoor method I use in the mouse event to the top:

    Uncheck the box if the SHIFT key is pressed while clicking on

    If (event.shift) event.target.value = "Off";

    The user will know that it is available. You can also configure a button that resets the value of the button to "Off".

    Another option is to add another choice, as "not applicable".

  • What is the best way to read this binary file?

    I wrote a program that acquires data from a card DAQmx and he writes on a binary file (attached file and photo). The data I'm acquisition comes 2.5ms, 8-channel / s for at least 5 seconds. What is the best way to read this binary file, knowing that:

    -I'll need it also on the graphic (after acquisition)

    -J' I need also to see these values and use them later in Matlab.

    I tried the 'chain of array to worksheet', but LabView goes out of memory (even if I don't use all 8 channels, but only 1).

    LabView 8.6

    I think that access to data is just as fast, what happens to a TDMS file which is an index generated in the TDMS file that says 'the byte positions xxxx data written yyyy' which is the only overload for TDMS files as far as I know.

    We never had issues with data storage. Data acquisition, analysis and storage with > 500 kech. / s, the questions you get are normally most of the time a result of bad programming styles.

  • How 2 change the name of image, including its .xmp file?

    How 2 change the name of image, including its .xmp file?

    I suppose that if I change image file name, the file '.xmp' that accompanies it will no longer an appropriate reference to associate. Also, I guess I can just simply change the name of the image file and give its eponymous .xmp. That means, for example, if I have:

    "This1stPhotoOfJane.dng" and "This1stPhotoOfJane.xmp"

    and change their names manually:

    "JanePhoto1.dng" and "JanePhoto1.xmp"

    It would not work.

    So is the simple way to do it?

    I have a bunch of files that I forgot to name who have already gone through the raw editor and now I would like to give them a real name as opposed to a single series of numbers they currently have.

    You should be able to bridge, since by default, the file of the side car is hidden. I think he knows enough to rename both.

    Copy the image and the file in a temporary folder, rename it and check that it actually did. If I myself remember copy or film a raw file would also move or copy the file, then it would be a good time to check that as well.

  • How to export the same MB size of my cr2 files in jpg or tiff files in Lr?

    How to export the same MB size of my cr2 files in jpg or tiff files in Lr?

    Let's say that my height is 22 MB, when I export the file in TIFF or jpg, although careful Iam with size of file settings, size, resolution, I can't manioukate how I want it.

    With jpg I tried everything, no matter what I do or a change in file size or meanless remains the same size - 7 mb instead of 22...

    Please advise,

    Best wishes

    T

    You should not even try to do it.

    JPG uses compression technology, so the files will have to be smaller than the original size of your RAWs. In addition, JPGs are 8-bit, while your RAWs are probably 14 bits, so the size needed to store your image will be smaller.

    Thus, there is absolutely nothing wrong with getting a 7 mb JPG of a 22 MB RAW.

Ive tried many things to stop it. Please help and thank you for your time

    Kevin

    Do you mean the page modules ordinary (the one that opens when you press Ctrl + Shift + a) or a page for a specific module?

    You get the unwanted page when you launch a new window (Ctrl + n)?

    If so, which may indicate:

    • One of your modules displays the new page.

    If the extra page does NOT appear in a new window, could test you using your Firefox desktop icon a second time without closing Firefox? This should launch a new window.

    If THE new window has the unwanted page, your shortcut of Firefox can be hacked. You can check by right clicking it > properties > Shortcut tab. The goal for 64-bit Windows 7 should be either not less the following:

    "C:\Program Files (x86)\Mozilla Firefox\firefox.exe"

    If THE new window does NOT have the unwanted page, Firefox may show a 'one time' page and failing to mention that he showed on the page, so it keeps only once the action at every start. Have you noticed Firefox remember other changes of parameters of the problems? This article has a range of suggestions to address this kind of issue: How to fix preferences that will not save.
