• How can I get color values premultiplied by one pixel?

  When you use BitmapData.getpixel32 (), find multiplied RGB color so if red, green or blue have been 0, you will get a value of 0 or if you have two colors with competing values for red and green, you will get the same value, there is a lot of information loss and I need to some how get it all.

  Can you think of something?

  Hello

  as I undestand the solution is written in docs:

  var bmd:BitmapData = new BitmapData(80, 40, true, 0xFF44AACC);
  
  var pixelValue:uint = bmd.getPixel32(0, 0);
  var alphaValue:uint = pixelValue >> 24 & 0xFF;
  var red:uint = pixelValue >> 16 & 0xFF;
  var green:uint = pixelValue >> 8 & 0xFF;
  var blue:uint = pixelValue & 0xFF;
  

• Script folder level? How can I use the value of a field as a pdf file name to save as dialog box

  I read somewhere that if you use a script to the folder level, you can do things like save a PDF with a specific file name - possibly based on a domain name.

  How we put in place a folder level script?

  How to run a script from the PDF?

  What code do you use to change the name of the PDF for the content of the text fFieldName field?

  Or is - this really just impossible to do?

  The function must be placed in a .js file in the following folder:

  C:\Program Files (x 86) \Adobe\Acrobat 11.0\Acrobat\JavaScripts

  You can then call it go another level of the folder or the document itself

  How can I determine the text in multibyte encoding (UTF8, UTF16, etc) who uses a database? I guess I can query a system table, but I was not able to determine that.

• How can I determine if I have firefox 64?

  How can I determine if I have firefox 64-bit?

  Hello

  I had a look on the details of the user agent for your version of Firefox, and it indicates that you are using a 64-bit version of Windows, but Firefox makes use of a subsystem called WoW64, which allows him to run a 32-bit version of the software as Firefox.

  There are currently no 64 bit version of Firefox, but there is a version that is in beta version (you can download it here) and the developer edition of Firefox (which you can download here). Please note that these are not fully completed versions of Firefox you may encounter a couple of issues that would be otherwise corrected before the code skips to the release.

  I hope this helps, but if not, please come back here and we can look at another solution for you.

• How can I change the value of a control on front panel?

  On the front panel, I'm doing a complex control that consists of a Slider control and control of the digital inputs. Both controls display the same information and either may be used for entry. When changing value, I want the other control to display the same value.

  How can I change the value of a control on front flap when another control changes the value? I know how to use a structure of the event to detect value has changed, but I do not know how to impose control on front panel to change its value in the block diagram.

  Why do you not use a digital display on the slider, and no code is required:

  How can I determine what my passwords for my laptop?

  I'm only guessing, but I think that it includes the administrator password, or possibly a password for the computer itself.

  I tried changing the settings on THE ADMINISTRATOR ACCOUNT.  I tried several times but without success. I can't even to appear administrator account.

  Oh, a separation of thought here.  I hope you better treat that you have treated others.  I don't appreciate someone implying that I am "breaking into any computer.  Microsoft makes it easy for me..., you just made me angry.

  First of all, please cite what anyone in my message that was humiliating or derogatory.  I'll gladly apologize for it.  I am sure that you will find nothing, however.

  By reflect, if you use a method to access a PC that bypasses the password, you're violating in this computer, if it's yours.  It is a fact, but it is not an insult.  Not where I "talked down" for you.

  I also noticed that despite your not like my answer, you nevertheless marked as the answer, it is in this context.

• Error-50352 DAQmx: How can I determine the maximum size of the buffer?

  I use a card PCI-6259 with DAQmx (version 9.0.2) library and I get the error "-50352: memory cannot be allocated" whenever I try to make my record too long. Here are a few terms that I found:

  1 channel of AI, 1Msample/s: 7.71 sec max

  1 channel AO, 1Msample/s: 7.71 sec max

  1 channel of AI, 500ksample/s: 15,4 sec max

  2 channels of AI, 500ksample/s: 7.71 sec max

  1 HAVE, AO, 1Msample/s 1-channel: 5.6 sec max

  IF I can't acquire more 7.71 Msamples in a single task, be it in most cases, or AO. When you mix tasks HAVE and AO, this limit seems to be decreasing. This happens with a freshly started application, so I don't think that it is a question of compensation task.

  What is a physical boundary with the device? (And if so, how can I determine this limit?)

  My impression is that the device uses DMA to transfer samples to the system memory, which there are plenty - I can easily allocate more than 400 MB of contiguous memory in the same application.

  Hi Luke,.

  The amount of RAM your system installed?

  What operating system do you use? If it is a 32-bit operating system, using 3 GB or increaseuserva? These parameters have a compromise: they reduce the size of the kernel virtual address space. This increases the probability of DAQmx will succeed to allocate memory but do not reach the mapping in the kernel virtual address space.

  Your system has all the devices with very large memory mapped I/O beaches, such as a video card with a large amount of memory on-board? On a 32-bit operating system, this can reduce the size of the virtual address space of the nucleus by a significant amount.
