• Does anyone have an example VI for using the SendInput function in User32.dll?

  Hi all

  I am creating a VI that creates a click of the mouse.  I looked at the MSDN Web site and found that I need to use the SendInput function in User32.dll.  The problem is that some of the parameters for this function are nested structures.  How to use this function in a call library function node?  Is there already a LabVIEW wrapper for this function?

  Thank you

  MechEman

  I would use rather MouseEvent.  I looked at my VI and it can be cleaned up a bit, but it works for what you want to do.

• How can I use the BCGTransform function to treat the 16-bit Image?

  Hi ~

  I use LabWindowsCVI8.5 and NI Vision to make the treatment of the Image. When I read the "IMAQ Vision for LabWindowsCVI Reference Manual", I found that the imaqBCGTransform function only supports 8-bit Image, while I do the BCG to turn on 16-bit image. Are there solutions to use the BCGTransform function to deal with the 16-bit Image? Or any other feature that could make the correction Gamma, contrast and brightness on the 16-bit Image?

  Thank you very much!

  because imaqBCGTransform is implemented as a lookup table, we can understand why it is limited to 8-bit images.

  Now let's take a look at the definition of each of this mandate (from the NI Vision Concepts documentation):

  -brightness: a constant added to the components red, green, and blue pixel of color over color, decoding of the process;

  -contrast: a constant multiplication factor applied to the components of the luma and chroma of a pixel of color in color to decoding process.

  -gamma correction: expand high gray-level information in an image while removing information of low level of gray.  (the chapter on lookup tables gives some examples of corrections gamma)

  now that you understand that this transformation is a simple mathematical function, simply calculate the correction for each pixel on your 16-bit images.

  I know not the exact formula used by the imaqBCGTransform function, but you should be able to approach by performing some tests on images 8 bits with the original function... or you can make your own formula... or find one on the net... or you can ask someone at home OR you give the formula...

• How to use the add_months() function in a mapping?

  Hello

  I have a variable in ODI with a date and I need to add another variable to add 'x' months...

  How can do that?

  Thank you

  If you say you have variable1 organise a date for example 01/01/2015 and variable 2 holding a certain number of months for example 7?

  If so in your mapping expression simply use the date functions available to your database technology (step/target) and replace the variable in the function

  that is for Oracle your mapping would be ADD_MONTHS (#Variable1,Variable2of #)

• SQL using the analytic function

  
  Hi all

  I want a help in the creation of my SQL query to retrieve the data described below:

  I have a test of sample table containing data as below:

  State ID Desc

  MICHAEL 1 T1

  ACTIVE 2 T2

  T3 3 SUCCESS

  DISABLE THE T4 4

  The thing I want to do is to select all the lines with an ACTIVE status in the table but is there is no ACTIVE status, my request will give me the last line with MICHAEL status.

  I can do this in a single request by using the analytical function for example, if yes can yiu help me on the request of unpacking.

  Kind regards

  Raluce

  Something like that?

  I had to fix it.

  with testdata until)
  Select 1 id, "T1" dsc "DISABLED" status of Union double all the
  Select 2 id, 'T2' dsc, the status "ACTIVE" of all the double union
  Select id 3, "T3" dsc, the status of 'SUCCESS' of all the double union
  Select 4 id, "T4" dsc "DISABLED" status of double
  )

  Select
  ID
  dsc
  status
  of testdata
  where
  status =
  -case when (select count (*) in testdata where status = 'ACTIVE') > 0
  then 'ACTIVE '.
  Another 'DISABLED '.
  end
  and)
  ID in (select id from testdata where status = ' ACTIVE')
  or
  ID = (select max (id) in testdata when status = 'DISABLED')
  )

  STATE ID DSC

  '2' 'T2' 'ACTIVE '.

  Maybe it's more efficient

  Select
  ID
  dsc
  status
  of testdata
  where
  status =
  -case when (select count (*) in testdata where status = 'ACTIVE') > 0
  then 'ACTIVE '.
  Another 'DISABLED '.
  end
  and
  ID =)
  -case when (select count (*) in testdata where status = 'ACTIVE') > 0
  then id
  on the other
  (select max (id) in testdata when status = 'DISABLED')
  end
  )

• How to use the NVL function to a parameter with comma delimited values

  Gurus,

  It is confusing to me.  I am trying to use the NVL function, but the setting that I'm passing in my cursor contains multiple values with commas.  The NVL function is confused when analyzing the values.

  'Where' cursor clause...

  and nvl (sn.c_attribute1,'x@#$%') in nvl (p_desig,'x@#$%'( )

  translated parameter values...

  and nvl (sn.c_attribute1,'x@#$%') in nvl ('SPRT''GOOD' 'BAD' 'x@#$%') -NVL does not parse the value correctly

  Any idea on how to get NVL recognize 'x@#$%' , if p_desig is null?

  Thank you

• How to use the Substring function with Case statement.

  Hi all
  
  I have a requirement where I have to use the substring function on the ground for the report criteria.
  FOR EXAMPLE
  I branch domain name where I have all the information of the branch names, now some of the branch names are too large with an extension after the name.
  now I want substing it, but the length of characters varies for each branch.
  so is it possible where we use a box where we can define if the character of name plug exceed a value then he substing with this length.

  Try something like this:

  LENGTH WHEN CARTER (tablename. Branch_Name) > n THEN SUBSTRING (...) Of ANOTHER tablename. Branch_Name END

  where n is the number of characters that you want to start the break.

• Using the crypt function

  Hi, I have a login page and I want to encrypt the password. What I must first encrypt it and place it in the DB? I already have a 'normal text' user name and pass word in there to test and everthing works fine, I restrict access to work on the admin page after login. So, my next step is to harden a bit of security. I searched the web and couldn't find static function crypt as examples below. Not quite normal I have to do. I read on another site where you would need to put passwords in the DB already encrypted by PHP and then write a script to compare. I don't necessarily want to create passwords encrypted on the fly (I think), as in the case of a new user type scenerio, are some users to access the admin section and want these "*" appears in the password field.

  Yes. The best way to do it with PHP is to use the sha1() function,
  which produces an encryption of 40 characters in a string. This means that
  your password in the database column must be 40 characters wide.

  Dreamweaver is not a way to encrypt the data before inserting it into
  the database, you will need to do it manually. Put this at the top of the
  page contains it the user registration form:

  <>
  If (isset($_POST['password'])) {}
  $_POST ["password"] = sha1($_POST['password']);
  }
  ?>

  > I read on another site
  > where you would need to put passwords in the DB already encrypted by PHP

  All you need to do is add the same code as above at the top of the page
  who uses the Log user Dreamweaver Server behavior.

  > wanting * to show
  > upward into the password field.

  This is done by selecting the password for the TextField input Type
  element in the property inspector.

• How doi send texts using the speech function without hitting the Send button?

  using the speech function in texting, how to send the text without actually pushing the Send button? When I say 'send' or 'send message' he just keeps typing

  "Hey, Siri, send a message to Bob. Siri will then ask you what you want text Bob. Once you stop dictating, Siri will ask then if you're ready to send the message. Say, "Yes." It's really very nice.

  If you are already in the message app and using speech-to-text, you must press the Send button.

• Cannot use the Val function in a script use

  I'm trying to convert a text string (binary number) in a number by using the Val function in a script of use but the colors of tiara the term Val in red and the script produces an error indicating "Variable is undefined:"Val"

  Why is that happen? Some functions are not allowed in use scripts?

  In addition, it seems impossible to use debugging in my use - if I try to add a variable to the Watch window, there never have any value even if I put a breakpoint on this line of code. Would it not possible to debug scripts use?

  David,

  regarding your question on "Val" I would like to direct you to the "File.Formatter.ParseString" function which is part of the API available at DataPlugins.

  CDbl and CLng do a good job in general, but they are dependent on the local configuration of the PC. 'ParseString' is so much more reliable.

• When I use the library function node call in real time, is loaded only once for all or load the DLL whenever it is called?

  When I use the library function node call in real time, is loaded only once for all or load the DLL every time when it is called?

  I have a critical application in real time, in which I use a piece of DLL function developed in C++.  It is ok?  Make sure any senior developer?

  Thank you in advance.

  The user interface thread is the thread that is used to update the user interface. It's slow. And it's supposed to be that way because humans are slow.

  The call library function node can be configured as this thread to use in the configuration for it dialog box. Please visit the LabVIEW documentation on how to do this.
