• How to detect the number of channels on an oscilloscope?

  I have various models sitting around the laboratory, some two-channel, a few four-channel oscilloscope.  I would like for my program to be able to detect the number of channels is available.

  I can just tell my program how much string is available based on the model number, but is there a VISA command to request scope directly what channels he has?  I would also be able to ask what, if any, ability to function math there.

  "all drivers of the oscilloscope must return the instrumentID after initialization, and that should be enough to know the number of channels.

  What Albert was referring to is that all compatible drivers IVI in their base class interface have an attribute/property that indicates how many channels has the scope.

  If you don't want to use the driver of the IVI for the scope then maybe download some of the drivers and check the source code to see how they calculate this dynamic repeated capablity.

• Detect the number of boxes checked

  Let's say I want to detect the number of checkboxes selected in a container, how would you do that exactly? Is there a way to get the properties of the child elements?

  This has been me all day stumping. Thank you.

  There are many ways to detect the active elements. Why don't you examine them in Javascript? If you know how much check you have in the container boxes, it's the best way I think. You must add each box an id and when of the event triggers (e.g. Press button, navigate forward), you check each property check checkboxes in Javascript, as:

  onClicked {
   var checkedNum = 0;
   if (checkBox1.checked) checkedNum++;
   if (checkBox2.checked) checkedNum++;
   if (checkBox3.checked) checkedNum++;
   etc....
  }
  

  But if you dynamically create checkboxes, you can get the full list of the QML next to C++ object.

  In the projectName.cpp file is a few lines generated automatically:

  AbstractPane *root = qml->createRootObject();
  // set created root object as a scene
  app->setScene(root);
  

  The root object contains all of the QML hierarchy. You can get it with this command:

  QObjectList children = root->children();
  

  Thus, the child is a list, and it contains elements of QObject. They may be iterating through a single for the cycle. Every QObject knows its class name, so with this code snippet, you can examine, whether or not the real QObject is a checkbox.

  for (int i = 0; i < children.count(); i++)
  {
    if (children.at(i)->metaObject()->className() == "CheckBox")
    {
      //do something
    }
  }
  

  I hope it helps.

  see you soon,

• How to detect the color pages in a PDF file?

  I use a plug-in of Acrobat C++ read/modify a PDF file.

  I need to get the total number of pages in the PDF file and the page numbers of the pages in color.

  So far, I was able to get the total number of pages using PDDocGetNumPages() with no problems.

  However, I can't find an API that lets me know if a particular page is color or not. Is there a way to do this?

  Thanks in advance!

  But what happens if there are RGB data which means black or grey (R == G == B), that means black or RGB?

  There is a code sample in the SDK to browse content in the PDF file, and then you can get the color space and color of each object.

  But you really need to do background research on the colors & spaces to achieve this properly.

• How to control the number of fields in the Advanced mode in &lt; af:query &gt;

  Hello
  
  How to control the number of fields in the Advanced mode in < af:query >?
  
  Say I have 20 fields in my table, and I created a view of criteria with 2 fields. This would work perfectly in basic mode. But in Advanced mode , the choice of fields is possible by clicking on the Add fields button. I didn't have the customer to search with all 20 fields. Only 10 fields must be listed in the Advanced Mode, even if there are 20 fields in my table.
  
  How can I control the list of fields in ADDFields button?
  
  Any ideas?
  
  
  
  KR

  You can uncheck the contestable ownership of attributes that you must not appear in the Advanced Mode (but they will not appear in the other modes too!) or by programming the value the same as those mentioned here.

  Also, you can hide the button AddFields as suggested here - http://www.notjustjava.com/2011/12/cool-tips-to-showhide-components-of-the-query-control-of-adf/

• How to count the number of data records?

  Hey guys, how to count the number of records, I had on a data object variable?

  Im having a result of sql query in a variable like this:

  oDB.resolveNode("#command").query.select.value = "SELECT * FROM Customers WHERE CliNombre LIKE ' % ' + input1 +" %' ";

  oDB.open ();

  oDB.first ();

  So I need to count the number of records retrieved by this SQL query at the moment. Help please

  Then move the cursor back to the first record after you have your account.

  There is a keyword count in SQL that will allow you to get the account of your request. You can run that first - get your account, and then run the actual query to get the Recordset. This would require a separate data connection. Some examples of code.

  var xfa.event.newText = inName;
  If (inName == "") {}
  App.Alert ("you must enter a name--try again!")
  }
  var nIndex = 0;
  While (xfa.sourceSet.nodes.item (nIndex) .name! = "DataConnection2")
  {
  nIndex ++;
  }

  oDB = xfa.sourceSet.nodes.item (nIndex) .racing var (1); pertaining to the specified data connection node
  App.Alert (ODB.saveXML ("Pretty"));

  var nIndex = 0;
  While (xfa.sourceSet.nodes.item (nIndex) .name! = "DataConnection3")
  {
  nIndex ++;
  }
  var oDBCount = xfa.sourceSet.nodes.item (nIndex) .racing (1); pertaining to the specified data connection node
  Configure sql call DB to get the number of records that match the criteria

  oDBCount.nodes.item (1).query.setAttribute ("text", "commandType");
  oDBCount.nodes.item (1).query.select.nodes.item (0) .value = "Select count (*) from table1 where AcctNumber = '" + inName + "'";
  oDBCount.open)
  oDBCount.close)

  Configure sql call DB to get the specified employee number

  oDB.nodes.item (1).query.setAttribute ("text", "commandType");
  oDB.nodes.item (1).query.select.nodes.item (0) .value = "Select * from table1 where AcctNumber = '" + inName + "'";
  App.Alert (ODB. Nodes.Item (1) .saveXML ("Pretty"));

  now connect to the DB and get a recording
  oDB.open)
  oDB.close ();

  Note the SQL command use the keyword count (take a look at the oDBCount section). This will return a number of return to the cllaer. When I set up the data connection, a node count (*) that appeared there. I dragged to the form and it has created a field called count that the onus at this node. When the query is executed, the number of resulting records returns to this field. You can have hidden it so that your users can not see it and also to change the binding votes to zero, so it is not included in the data file that is submitted when the form is complete.

• How to find the number of data items in a file written with the ArryToFile function?

  I wrote a table of number in 2 groups of columns in a file using LabWindows/CVI ArrayToFile... Now, if I want to read the file with the FileToArray function so how do I know the number of items in the file. during the time of writing, I know how many elements array to write. But assume that I want the file to be read at a later time, then how to find the number of items in the file, so that I can read the exact number and present it. Thank you all

  Hello

  I start with the second question:

  bytes_read = ReadLine (file_handle, line_buffer, maximum_bytes);

  the second argument is the buffer to store the characters read, so it's an array of characters; It must be large enough to hold maximum_bytes the value NULL, if char [maximum_butes + 1]

  So, obviously the number of lines in your text tiles can be determined in a loop:

  Open the file

  lines = 0;

  While (ReadLine () > 0)

  {

  lines ++;

  }
