Determine if a string contains an expression of certain

• Check that a string contains data only numbers

  Hello

  I'm trying to find an elegant way to test an input string "serial number" format A00000000 (where A can be any letter and 0 can be a number any).  My first thought was to check the following features:

  (1) total string length = 9.

  (2) using the "Decimal String to the Number.vi", result = 0 (which indicates that the string contains no numbers).

  (3) using the 'Decimal string to Number.vi' with an offset of 1, the result is a number.

  Unfortunately, that does not differentiate between the following strings:

  A00005123 valid

  Invalid A5123

  Invalid A5123B123

  Invalid A005123BC

  All the world is this recently?  Is there a way to analyze non-specific chips (for example separating the groups of letters, numbers or other?)  Is there a complete way to do this without breaking the chain in 9 individual items and do a comparison of 26 item for the letter and 10 element for each number comparisons?

  Thank you

  You can use a regular expression to match the pattern.

  

• Order findstr/l/s/m print the file names of all the files in the directories and subdirectories despite any string contained

  Hello

  I'm looking for a file via the findstr command. After that I opened the command as Administrator window, I get:

  Findstr/l/s/m 'a string containing the words. " *

  Then, the command window displays all the files in the directory and its subdirectories. I think that I see which file is searched for the chain in real time.

  I expected to see only the name of the file/s if the string was found in it.

  What I am doing wrong? or why is this malcfunctionaning?

  I got directions for ordering findstr here: https://technet.microsoft.com/en-us/library/bb490907.aspx

  Thank you

  I think you want the /c parameter instead a / l.  As written, your search string is interpreted as a list of strings: 'a', 'string', 'with' and 'words '.  Any file that contains an 'a' will be a return match.  The parameter/l keeps your strings to be interpreted as regular expressions.

  If you need exactly match to the entire chain, type:

  Findstr /s/m/c: "a string containing the words." *

  Under the direction of add: It is not clear, but you can have several settings/c , to search for more than one exact string at a time.  For example:

  / s/m/c: 'a string' findstr / c: "a Word." *

  Research is 'a string' or 'a word' exactly.

• How to convert the Ascii string containing hex to hex string info?

  Dear all,

  I am busy doing a control/reading program for pumps of ISCO.

  Right now I'm in trouble with to send orders for PUMPS in HEXADECIMAL. When I use a CONTROL to the STRING in HEX display, everything works fine (when I manually write down the command in the control of the chain).

  Exist it a couple of pieces order: string Destination, length, ordering, Checksum. I'm doing a sup - screw that automatically calculates the checksum (modulo 256) and adds it to the string. Everything is going well: first of all, I shared the ascii bytes command and I calculate the checksum and add as ASCII HEXADECIMAL value to the chain of command. Also a CR (= 0d) is added. Now the whole string must be converted to hex. The string contains the right nummers HEX, but they are in ASCII format. Here was I feel worth it, I don't know how to do it!

  So to summarize:

  I have an ascii string that contains the values HEX (for example 315230303652454D4F544531420D) and it must be converted to a HEX string (for instance 3152 3030 3652 454 4531 420 4F54) for the pump of the ISCO can understand the command.

  The VI is attached.

• Is there a way to parse a string containing % (percentage symbols) using the function 'analysis of the chain?

  I am communication in series with a mirror device and the syntax of the input string contains this text: "% hr ="

  I was not able to find a way to say to the function that the percentage here is not a format specifier. Is it possible, or should I just try to use a different function?

  Thank you.

  Use %% in your format string for what he knows to use the percent literally.  So % RH = %f

  

  EDIT: Darin has one here in front of me.  It seems to be-% and % both work.

• Test whether the string contains the only slash the other way around?

  Hello

  How do you do that?

  I need to check if

  (a) the string contains two consecutive backslashes

  (b), if not, check if there is at least an oblique bar opposite

  If (test.) IndexOf("\\") > = 0) seems to knock on a string that is 'ss\\ss', but I have a feeling that is incorrect. I think it's really just test for 1 backslash.

  AS3 and don't let you do if (test.indexOf("\") > = 0), as the single backslash escapes the rest of your code.

  It is to test for the existence of a or two backslashes in the ID3 tags, as some editors use as a delimiter for multiple tags within the category of a tag for example kind: rock\\pop, or rock\pop

  Thanks for taking a peek.

  {if(s.IndexOf("\\\")>-1})

  There are two or more backslashes consecutive

  } else {if(s.indexOf("\\")>-1)

  There is that a single backslash

  }

• How can I determine which text fields contain data?

  Although it is a sad testament to my programming skills, I'm little embarrassed because I'm only doing this sort of thing maybe once every two or three years.  I am using FormCalc (mainly b/c I'm still learning Javascript and this form had already been written in FormCalc).

  Here's the problem:

  I have three text fields (Textfield1, Textfield2, Textfield3).

  I created three variables (var1, var2, var3) and initialized to 0.

  To determine how many fields containing data, I used the if/then/else statements:

  If (Textfield1.rawValue == "") then

  var1 = 0

  on the other

  var1 = 1

  endif

  Textfield2 and Textfield3 have similar statements (respectively using var3 and var2 variables).

  To test the code, I have a message box returns the sum of var1 + var2 and var3.  With NOTHING entered into all fields of text, I expect him back a sum of 0, but it returns the sum of 3!  If I enter data in only one or two of the fields, yet once it returns a value of 3.

  I tried the initialization of the value of the Textfields (Textfield1.rawValue = ""), but I always get a value of 3.

  This is probably a simple programming error, but still, I'm not a developer.  Any help would be appreciated.

  I think that you may need to modify your code for: (replace the "with the null value). Change of FormCalc to Javascript

  If (Textfield1.rawValue == null) then

  var1 = 0

  on the other

  var1 = 1

  endif

• Say Actionsript to read a string as an expression

  I need help, solve a unique problem.

  So, how I can tell flash to read my result. For example, as an expression instead of a string.
  
  Is there a class for an expression as it is for string or Boolean?
  
  Or is there a way to pass variables to an expression?
  
  myVarible = example
  
  myData = new LoadVars();
  myData.onLoad = function() {}
  myDynamicTextField.text is this. + myVarible; < < < < this unfortunately returns 'this.myVarible' to myDynamicTextField

  You can either use the eval() function to evaluate the combined string.
  or you can use the array access operator. The access to the array operator
  requires a parent object, then solves a string to an object reference...

  for example
  This. Example of
  ... is the same as...
  This ['Example']

  Now, in your case, you're even putting "this" in quotes. Don't know if
  you need to do. If so, I guess that you can evaluate the string on your
  own to see if it is equal to 'this', then provide the object on its reference
  clean.

  > myData.onLoad = function() {}
  > myDynamicTextField.text = this. + myVarible;
  > returns
  > "this.myVarible" to myDynamicTextField

  If the $myvariable value is a string that references a property inside
  The myData object, then that should do it...

  myDynamicTextField.text = this [myVarible];

  ... as long as the $myvariable variable falls under of this
  function.

• How can I reusable component of PPR - java to determine the complete naming container?

  Using JDeveloper 11.1.1.4.0
  
  I'm trying to find a way to refresh (PPR) a reusable component when the chain of full path of containers is not available during the design of the component. I want to do the truly free and reusable component confined. If the component was used only on one page, the string of path names naming container would look like "document: model: region: panelcollection:table. However, I don't know what the real string would look like before panelcollection I see this component. In java, how can I determine the full chain of names naming container to pass to a method of partial page refresh? The method I use to update with is lower (uid would be = to the full chain of names naming container). If there is another way to get a RPP on a component, I'm also open to trying this.
  

      private void partiallyRefreshUIComponent(String uid) {
          FacesContext fctx = FacesContext.getCurrentInstance();
          UIViewRoot viewRoot = fctx.getViewRoot();
          UIComponent component = viewRoot.findComponent(uid);
          partiallyRefreshUIComponent(component);
      }
  
      private void partiallyRefreshUIComponent(UIComponent component) {
          AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance();
          if (component != null) {
              adfFacesContext.addPartialTarget(component);
          }
      }

  Thank you

  Hello

  If the outside of it, you can declarative set up the component for PPR. If you want PPR components inside in the declarative component, then generally refresh is in response to an event (ActionEvent, ValueChangeEvent) on another component in the declarative component. The event object, you get the event source by calling getSource() or getUIComponent(). If the Update component is a close relative, you just call findComponent ('id') of the origin of the event to find a refreshing it.

• Is there a way to differentiate the string containing the characters and numbers?

  Hello, I created an application to read data from a serial port device. The problem is that the device, at startup, displays a block of text that contain characters describing the device. Shortly after, he displays a command prompt "command:" it's when I want my VI to enter the command to start to take action.

  I was looking at the VISA waiting on the event and looks that could be used to wait for the output device, only a "Serial character", but there is no distinction between the letters and numbers that I can tell.

  If the device is out of numbers in the reading string, of course, no need to enter the command to start to take action once again, which will probably only confuse the device. In this case, I want my VI to continue taking measures with VISA Read.

  The reason is that when I run the application, the device may have already been turned on. Send this command to the device using VISA Write is not necessary at this time.

  Any advice would be appreciated. Thank you.

  This makes it much easier.  In this case, this will do the trick.  You will notice that the bottom of the case does not match even if it has valid values inside.  The only thing that will match if the entire string is of the form XX. XXXX. Incidentally, since we are only matching numbers now, you can remove the "ignore case" Boolean as there is more important.

  

• Check if a string contains "text" in a box, and only if it does not, add it to the chain.

  I have some comboboxes. I want a text field to add a channel to itself, that contains the text selected in each combobox. I got it with this:

  var a = this.getField ("CoBi_text");

  for (i = 1; i < 16; i ++) {}

  var t = (this.getField("CoB_"+i).valueAsString);

  Si (t ! = « ») {}

  a.Value += t + ',';   }   }

  But what adds text even though I select the same option in any of the combobox control. How can I include a conditional don't skip the increment if "the text is already in the string?  I tried this:

  If ((t! = «») & & (a.value.indexOf ("t") < 0)) {}

  a.Value += t + ',' ;}

  But it causes the chain add the text first, don't increment not any text more after that.

  PS. This text field will be hidden and later used on another condition (if it contains 'a specific text'), some other triggering actions.
  So the ',' (comma) is probably not necessary, but I think that it should not be in the way of a proper search indexOf (right?)

  Thank you.

  eHRM, nevermind. I got it.

  the "t" inside indexOf should not "s...".

  var a = this.getField ("CoBi_text");

  for (i = 1; i<16;i++)>

  var t = (this.getField("CoB_"+i).valueAsString);

  If ((t! = «») & (a.value.indexOf (t))<0) )="">

  a.Value += t + ',' ;}

  Now, he adds "text", but not more than once for each different text on each drop-down list.

  There is always the question of the modification of a selected item in a combobox control, how do I remove the old text from the text box but I think than any forced recalculation should be enough.

  Thank you for taking the time to respond and for the link!
