need a little help with time calculation


I tried to implement oauth2 and youtube api. I can connect and can recover the access_token and other oauth required as expires_in json values.

What I'm trying to do is drive if my access token is valid or not before making another call to their api - youtube gives a value - expires_in that normally contains 3600, which I suppose is seconds. I'm trying to add this time now using clock_gettime(), but I don't get correct values for my calculation - nowTime + expiresInt.

Anyone can point out the problem with my code please? It could be a bad way to do it, but I thought that I spent a few hours on this subject before asking for help.

Thank you.

token = c.value("access_token").toString().toStdString();
    refreshtoken = c.value("refresh_token").toString().toStdString();
    saveValueFor("access_token", QString::fromStdString(token));
    string expires = c.value("expires_in").toString().toStdString();
    saveValueFor("refresh_token", QString::fromStdString(refreshtoken));
    struct timespec* start;
    clock_gettime(CLOCK_REALTIME, start);
    int nowTime = start->tv_sec;
    std::stringstream str(expires);
    int expiresInt;
    str >> expiresInt;
    nowTime += expiresInt;
    stringstream nowTimeString;//create a stringstream
    nowTimeString << nowTime;//add number to the stream

Now you install milliseconds and seconds.

  • Need a little help with AE

    Hi all, I'm having a small problem with After Effects. I'm a Design student computer games of second year and I'm trying to wrap my different modules for the year.

    One of my modules 3D and animation, I made my last animation output as PNG. There are tired of running at 24 frames per second depending on the 22 second audio clip. When I put the images in After Effects as a sequence PNG sequence is only 18 seconds long and makes out in 18 seconds.

    I put the composition 22 seconds long and do speed 24 seconds when I started the comp. I have a layer of PNG (images you will see) and a second layer of PNG (a rendered 3D Studio Max Zdepth) to create a depth of field effect.

    How can I get these PNG to make out at the speed I want? They always make out too fast.

    This will probably turn out to be something really simple, I apologize if this is! I tried to look online for other people asking, but I have too much time in the next week and can't afford to spend time looking around. I would be very happy if someone could give me a helping hand.

    Thank you.

  • So I need a little help with the Flash colors

    I always use the red, green and blue gradient colors Flash below for metal stuff, but how do I get the effect of this red color in different colors like yellow?color.png

    If you want to use predefined gradients, what you could do is the first color any field you want with one of them, and then select the fill and use the color Panel to replace the Red some other color you prefer.   If you have never worked with the degraded section of the color Panel, you will be probably it find a bettter tool to create and fine-tune transitions.

    You just doubleclick, this little red square in the lower left and it opens a color sample as you have demonstrated to select another color

  • I need a little help with the INSTR function

    Hello everyone,

    im still new to pl sql and experienced an issue with the INSTR function. I need to analyze some values of a CLOB containing the xml code and use INSTR to determine the beginning and end of the value, I would like to analyze.

    the data I need is in a <!-[CDATA [[Some Text]]]-> block. up to this point, I managed to take the start of the word, but I can't seem to capture the end of the CDATA block. I use this statement:

    POS: = INSTR (TO_CHAR (input_clob) [,'] ', pos2 + 6, 1);

    but it doesn't have the desired effect. [It seems to sort of go back to the length of the string, while the]-sign is actually in the xml file. my result would look to "Some Text]]--> < xmlxml >... < / xmlxml >...» ». [I tried to escape by writing ' \] "but if I do, the function returns zero and my parsed string is left blank.

    Unfortunately I can't use regular expressions, because I work with oracle 9.2i. Anyone know what I'm doing wrong?

    Thank you

    Im trying to do some logical columns for calculations. It is a very simple calculation, but I can't seem to make it work in the repository.
    The data upon which I make eyes of calculation as follows.

    Issue Nr. | Question | Meet Nr. | Response | Answers (number of responses)
    1. | Job satisfaction | 1. | Very good | 8
    1. | Job satisfaction | 2 | Good | 2
    1. | Job satisfaction | 3 | Bad | 5
    1. | Job satisfaction | 4 | Very bad. 0

    It is an example of the data. Now, I want to make a logical column to calculate the 'happiness factor '. The formula looks like:

    (Very good + good) / (very good + good + good + bad) * 100 = happiness

    So it would be 10 / 15 * 100 = 66.66.

    Very simple, but I have no idea on how to accomplish this formula in the repository. What I was aiming for in my head, it was something like:

    Select the answers where [answer] Nr. (3,4) / select responses where [answer]. Nr in (1,2) * 100 = :)

    Does anyone know how to do this in the repositroy? It would be highly appreciated.



    This happens when we don't know all the facts and we create our scenarios and responses only what we know...

    Now you can do if you do not use 'no opinion' or 'Empty response' in our 'answers' but again to tuition assistance box...

    'All answers worth calculation' =
    case when answer in ('list of what answers I want to aggregate', ((Very) Happy... (Very) Unhappy))
           then 'my new All answers'
           else 'answers I need to ignore'

    and our dimmnesion should look like:

    'Type of survey' -> 'Question' -> 'All answers worth calculation' -> Happiness -> Answer

    in this case the levels should be no to the 'Question' but to our new "answers a calculation value..."

    So, for an issue with 21 responses it is only 6 entries ((very) happy, (very) unfortunate, Blank, do not know)
    A separate account solves your problem...

    In addition, in your last post I don't understand how you can sum UP non-numerical data (Happy/headaches)

  • Hi all, I need a little help to try to solve a problem of updating Bios for a long time.

    I downloaded the new update of the Bios on the HP site. But when I try to install the update, the process goes up to only while it presents me with an error. Any help would be appreciated, I am trying to upgrade the Bios for the new firmware in order to perform a better processor. Thank you...

    Error code: 3033

    "GoTo" label not found

    on line 89 of w:\patches\i...ate\windows\installer.wbt

    My system is...

    Compaq Presario SR1339uk

    Serial number: CZB5050HBW

    System number: PS267AA

    Motherboard: Asus PTGD1 - LA

    BIOS version: 3.13 12/14/04

    Operating system: Windows XP Home Edition

    Not sure what's going on here, but here is a suggestion on how to properly install manually the update of the BIOS.

    Assume that you download SP26760.exe (BIOS 3.28)

    Start the update - go to the last message you get before it fails and stop. (must be where it prompts you to close the applications and will be saved).

    Open a DOS (command prompt).    You must be an administrator - so if you're running Vista or Win7 - make sure that 'run as administrator ' at the opening of the box.

    Once in the BACK, type:


    go the the directory of temporary files.

    Then make a

    DIR /S 328.LE ROM

    to find the directory where the update files are located.    Type CD < directory name > to go in this directory (on my system, it was a folder called pft467D.tmp, but it might be different on your)

    CD pft467D.tmp

    Now manually invoke (the prompt back, no windows or the windows file manager) the update, with the appropriate switches.  By omitting the switches can cause other problems, as have reported activation of Windows problems.

    AFUWIN /i328. ROM /pbc

    For reference, on my system, here's what I saw in these folders:

    C:\Users\sumsolstice\AppData\Local\Temp\pft467D.tmp > dir

    Volume in drive C is DRIVE_C
    Volume serial number is FE8F-4AA6

    Directory of C:\Users\sumsolstice\AppData\Local\Temp\pft467D.tmp

    26/04/2011 11:11 < DIR >...

    01/07/2004 10:54 amifldrv.sys 6 912
    21/02/2006 18:08 526 374 Installer.exe
    09/05/2006 17:10 sp26760.rtf 1 784

    C:\Users\sumsolstice\AppData\Local\Temp\pft467D.tmp > AFUWIN i328.rom /pbc

    It should work OK, however no guarantee if there's something else - but essentially - that's what the installer should do.   If this does not work for you - I wouldn't try to force things - you can make a good motherboard unusable quickly.

    For those who are looking to this announcement - the syntax is for this motherboard only - switches may be different for different motherboards.

    Good luck.!

  • Need help with custom calculation Script

    Hey everybody.  I'm using Acrobat X Pro and stumbling a bit on the syntax of the following equation.  I need to add the value of "Cell1" & "Cell2" then add the value of "Cell3.  However, the value of "Cell3" is entered by the user and specifies a percentage of the sum of "Cell1 &"Cell2".  For example: If the user enters "3" in "Cell3" I need the value returned at 3% of the sum of "Cell1" + "Cell2".  If the user enters "9" in "Cell3" I need the value returned for "Cell3" 9% of the sum of "Cell1 and Cell2" and the end result should be the sum of "Cell1 Cell2 + Cell3.  In more detail:

    If "Cell1" = "Cell2" $ 500 = $500 and "Cell3" = '3' then I need the returned value to be $1030,00.

    I hope this makes sense. Here's what I have so far, but alas, it does not work.  Any help would be GREATLY appreciated.

    Get the first value in the field, as a number

    var v1 = + getField("Cell1").value;

    Get the second field value, as a number

    var v2 = + getField("Cell2").value;

    Get the value of a field, a number transformation

    var v3 = + getField("Cell3"/100).value;

    Calculate and set the value of this field for the result

    Event.Value = v3 + (v1 + v2);

    Thank you


    I have posted a reply, but realized that it wasn't what you wanted. There is some confusion about what you want for Cell3. A hand, you say that the user enter a vaule in the area, but them you say you want its calculated value based on what the user has entered and two other field values. It seems to me Cell3 should be the domain that the user enters the percentage, and the calculated field (Cell4) script could be:

    Get the first value in the field, as a number

    var v1 = + getField("Cell1").value;

    Get the second field value, as a number

    var v2 = + getField("Cell2").value;// get treatment field value, as a number

    Get the percentage

    var v3 = + getField("Cell3").value;

    Calculate and set the value of this field for the result

    Event.Value = (1 + v3 / 100) * (v1 + v2);

    I've never used Adobe Acrobat and know nothing about JavaScript.  I am creating a form of invoice.  I have it almost complete but can't do 2 things resolved.

    # 1, you can configure a custom JavaScript validate it is simply:

    // Custom Validate JavaScript
    if (+event.value === 0) event.value = "";

    # 2, use the simplified notation next to the calculation field:

    Parts * work * 0.085

    Replace 0.085 with tax rate that you use

  • New to Ae, need help with time remapping (tutorial anywhere?)

    I am very very big thing back to Ae (CS4) and I was with Premiere Pro CS4 to edit a video, but I need to speed up, but as many of you may know, when you use time remapping in Pr, the sound isn't sync.  However when you do it in Ae, it does.  Then...

    What I'm trying to do is to let the clip I am going for a bit of editing time, then gradually increase the speed to 250% of the original over six seconds, stay 250% for some time, and then gradually in the course of about six seconds to 100% of the original speed.

    I'm kind of having trouble finding how to use Ae well.  There are a lot of easy to understand tutorials out there for Pr, but I can't really find any good for Ae.

    You use the time remapping effect. In fact, when you enable TR, you will notice that the duration of the layer is not limited to the original boundaries more. You can extend beyond the layer's original point.

    So, what you want to do is to keep the TR keyframe at the point layer zero to a value of zero. Set a keyframe second point 06:00 of the layer, with a value of about 14:00 (if possible, because maybe the original clip has no more of any material). You did it like that because if you show 14 seconds of video in a six-second segment, the playback speed is about 250 percent speed. You can do better than 'roughly', but this would require using the speed graph...

    For the real variable speed to set the first keyframe (that at 0:00) to perform a "easy ease on", so the speed ramps up gradually (what means "mitigation" for any property). Setting speed to 100% can be reached at justwith degree sense, but to familiarize themselves with the speed graph will make much more accurate. I say common sense, because if you have a keyframe of a code value of time from 14:00 to 06:00, then a possible way to get back to 100% is to show four seconds of material in the four seconds left (in condition, once again, that your source material has something to 18:00). As you can see, TR needs abundant "handles" (IE, additional documents in the source layer) to work at its 'best.
