Guidelines to set the buffer size?

Are there articles or messages that describe the basic guidelines for choosing the sizes of memory buffer to use when acquiring data?

Are there specific problems that occur when the buffers are too large or too small?

Thank you

Dave

The buffer must be large enough to handle the data acquired during the long interval between reading th book.

Too small and encounter you problems if you do not read your data fast enough.

Too much and you lose memory.

My personal recommendation is "close your eyes and imagine the user trying to open a huge Excel spreadsheet while the application is running" - However for long, I suspect that the PC will have to open the file will dictate (based on the sample rate) what is the minimum size. In the old days, I would just double this figure. These days, I can use a 5 fudge factor.

  • Setting the default size of the popup window

    I need a way to set the default size of the popup window on a specific area or all areas (whichever is easier). There is a particular site that pulls up a PDF in a pop-up window, and always default to a small window, but I need full screen. Apart from the obvious 'simply click on the button full screen every time ", can someone offer me some suggestions? If it were me, I'd just hit the button fullscreen, but I'm trying to set it up for some end-users rather capricious. The device in question (if important) is a Tablet from Dell XPS 18, and the version of Firefox is 24.0, just installed about twenty minutes ago. Forums for research, the only thing I found remotely close to what I'm looking for is to force the popup to allow resizing; This isn't what I need; the pop-up window already allows resizing. I need a way to automatically open it full screen. Thanks in advance for your help.

  • Set the font size in the generation of explicit report using a model

    Does anyone know how to set the font size using the generation of explicit report with MS Word?  I have trouble getting my 11th column to fit the correct size with the imported data table.  The values end up being off the screen.  Any ideas?

    I suspect that the answer is somewhere within MS Word instead of LabVIEW.  However, I tried it figure out in both and had no luck.  In WORD, I updated all fonts size = 10.  However, the table is imported to the format = 12.  In addition, the table cells are the same size, regardless of the number of columns is imported.

    David

    Just for future visitors to this question are aware, it is a known problem with the generation of report express vi.  There is no solution at this time and the problem will be resolved in future versions of LabVIEW.

  • Can I manually set the maximum size of the thumbnail cache?

    I notice that in a folder with a large number of photos, there seems to be a limit to how much stored thumnails. If I quickly scroll the I get to a point where I have to slow down and wait for the thumnails to regenerate. I wish I could store all thums so I can go to any point in the subdirectory and see them with no delay (the whole point of a cache). I have 4 GB of RAM so I don't care if it uses a fair bit to do this. Y at - it a key option or the configuration of the registry to set the maximum size? I have Vista Home Premium x 64.

    Hello old giza,.

    Thank you for your response back!

    Except there is no way to increase the size for the thumbnail cache.  You are able to clear the cache and I saw on third party internet providers that offer this possibility.  But the operating system is not an option to increase.
    Maybe if you can give more details about what you're trying to do we can get to the best situation.  Please let us know status.  Thank you!

    I just updated my indesign to CC of CS5. One thing I notice which is annoying is some text boxes and images go live. For example, if you close a text box in CS5 you close the box you see reformat the text to set the new size. In CC, the text does not reformat until you are done change the size of the box. It's the same for the images when resizing or rotation re. You don't know what you have until its finished. If you are a little guess instead of see what you're doing while. Is there a way to change this, or does anyone else have this problem. Maybe it's just what does CC. But I'm not a fan... Can anyone help?

    When using the image processing manages, click... for a while... then drag...

  • How to set the default size for SWF published in Catalyst CS5.5

    I create a project of 800 * 600 pixels in Catalyst CS5.5 and published it as .swf.

    But when I open the .swf that is published, the default size is less than 800 * 600. I have to resize by myself.

    So is there any method I can set the default size for published .swf?

    Thank you guys! Best regards.

    Nick

    When you start the new Flash Catalyst project, you have the option to enable resizing

    This setting is enabled by default.

    If you need to change it later, you can go into edit > settings of the artboard.

    Now when you publish your project, the width and height will be there will substitute.

    As to manually file editting the HTML, there are 3 sets of tag that define the width and height of the project (to manage different browsers). You will need to adjust the values of each of these tag sets. You should just have to do if you cannot republish the file.

    I have two problems:

    (2) after Forefox crashed, my font size is tiny. I went to the System Prefs, display and general and can't find anything on the font size setting.  The font size is v smallon my tabs, although ' I can adjust what I am writing.

    What happened and what can do?

    Thank you!

    Do not forget that your Firefox is uptodate.

    Clear your cache and history as well.

    What about fonts:

    In Firefox 46 in the preferences search content and try to change.

    Note that in the content there is also a step forward.

    and the part that has a checkbox

    'allow pages to choose their own fonts '.

    Experience here.

  • How to get to 'see' to be able to set the font size? Too small, can't read, especially in Facebook.

    Suddenly, it seems that the police got so small, that I can hardly read it. I have good eyesight and a 21 or 22 "screen. But Firefox has only a single drop-down list, not others he used to have. I need to be able to define the size of the content on the screen. Help! Thank you!

    To the menu 'View' try to press 'Alt' + 'V' on the keyboard.

    To set the default zoom: "Ctrl" + "0" (zero)

  • Current playback position exceeds the buffer size? VB6 with NIDAQmx 9

    I have an application written in VB6 that does HAVE and AO, with both using the Ctr0 internal as the clock to check that they are in sync.   It seems to work very well.  I use a USB-6212 and a recent version of NIDAQmx.

    I am tracking the current playback Position by calling DAQmxGetReadCurrReadPos_VB6 in the EveryNCallback routine.

    Strangely, the value for each call correctly increases the number of returned samples (for example, 128), but instead of round package when it reaches the upper limit of the buffer (for example 16 * 128) it keeps growing to infinity.  No error is reported by the call to DAQmxGetReadCurrReadPos_VB6 or anything else.

    Am I misunderstood something?  This function seems to be to just return the total number of samples read, not the position in the buffer.

    What I expect the value of the current to be playback Position:

    128, 256, 384, etc..  the limit of the buffer for example 16 x 128 = 2048 how he could start over at 1 (or zero depending on the way which you set up your berries).

    Hi afmstm,

    The behavior you're seeing is indeed good, and I agree that the description that it is misleading.  The current description says:

    "In the samples per channel, shows the current position in the.
    buffer.

    The description should be interpreted as:

    "In the samples per channel shows the current position the acquisition."

    So yes, for a relative position within your stamp, you must perform a modulo operation.

    That being said, it's not the same thing as 'total number of readings/a. Since the beginning of the program' as you say.  This would be the attribute Total of samples by acquired chain .  It is rarely a chance where these two alignment attributes.  For example, to read N samples successfully the following must be satisfied:

       Total samples by acquired channel - current read Position = N

    Another distinction is that you, the user can change the current Position of playback using the properties relative to and Offset .  By default you will read from the current playback Position , which creates the behavior your described.

    I know it can be confusing, but this level of manipulation of streaming is a very advanced concept of DAQmx.  Let me know if this raises questions or concerns more!

  • DAQ Assistant don't update the buffer size to change the frequency

    Hi all

    I use DAQ Assistant inside a loop to write a signal in a module output best 9262 OR a cDAQ-9174.  I generate the signal with the express vi simulate Signal or with a simple loop using indexing.  The problem is that when I change the frequency, using the same sampling frequency, I have a different number of samples to write the cDAQ does not seem to update the size of the buffer, so no my signal gets written in.  The result is the first sine wave is nicely written, but each after that gradually get cut off on the edges.  I traced imput signal that I generate, so I know that it is generated with the right size and frequency of departure, what ever it is, still works, it is those more later in the loop who have the wrong size aparently buffer.  I tried to reset the cDAQ by adding a different DAQ Assistant at the end of the outer loop with the stop bit the true value, it makes me just the error "resource not available.

    Any ideas?

    I'm using LabVIEW Base development system new V12.0 32 bit.

    Thank you

    Matt

    Idea:

    Get rid of the DAQ assistant and use the DAQmx API.  The DAQ Assistant is there to support the limited functionality and base up a dirty experience and running quickly.  The report of the API offers more funcionallity and DAQmx property nodes allow greater flexibility.  DAQ Assistant is just too limited for your needs.  (you can't paint a masterpiece with crayons)

  • It is best to set the resolution size and icon of the screen up

    It is best to set the maximum screen resolution before attempting to adjust the size of icons and text on the desktop, notification area, Quick Launch bar and start menu? I know that the icons can be made to the largest and by choosing a lower screen resolution but y at - it a benefit to have the maximum resolution? My view is not too good and I need icons and text to be big enough.

    Hello

    The screen, or the screen resolution, resolution refers to the size of the whole image displayed on your computer screen. Specifically, he refers the number of picture elements, or pixels, which are displayed at the same time. A pixel is the smallest element on your computer screen, the more pixels, the more detailed the picture will be. With fewer pixels, display items will be larger, but there will be less space on the desktop for windows and the programs to run.

    You can visit the link provided below for more information about the screen resolution in Windows XP.

  • Is there a way to set the font size as default in WordPad - Windows 7?

    In Windows 7, is there a way to set the default value in WordPad to Courier 10? I see no place to set the default value. I save my changes and when I close and reopen the document it's back to Courier 11 and the spacing is all off. I create documents for customers who need very specific settings (including a 10 - PT font.) to copy and paste resumes to online applications. Once I have send the plain text for them, they, also, versions I can save these specific parameters. It's extremely frustrating; in XP and Vista, I was able to save 10-PT policy documents. I don't see why this was changed. Any suggestions? Anyone at MS have the power to solve this problem?

    I created a document called a new Doc - highlighted space vacuum-made my the font changes and size and saved.  So when I want a document with my size settings and the police, I opened my new Doc.  Make sure that when you save it you rename this new Doc remains empty.  I created a shortcut on the desktop and open the new Doc instead of WordPad.   I guess you can do your employees.  I hope this helps.
