Como obtener un array dbl de un string de 2 bytes
como obtener un array dbl de un string de 2 bytes
Adjuntos:
dbl.png 37 KB
Hola, un string de dos bytes no puede contener un double ya que el dbl es un número de 8 bytes.
Acaso estás recibiendo alguna medicion de un conversor de 16 bits (un instrumento externo, un PIC o algo así)? Si es así el valor correspondiente en la unidad de medición (V, A, RPM...) debe calcularse con
bits recibidos / 65536 * máximo de la medición
Ejemplo: en un voltímetro de 100V / 16 bits, un valor de 8000 (bits) equivale a una medición de 12.207V

Array of Ring to string value for creating a table
I want to convert an array of ring to string and generate a table from it.
But using property node for converting each ring is changing all the value of the table!
each array represents different register!hence required to change for different array!
i am hereby attaching a Vi!

Converting Image to Byte Array and then to String
Hi All...
Can anyone please help me. I have got a problem while converting a Byte array of BufferedImage to String.
This is my code, First i convert a BufferedImage to a byte array using ImageIO.wirte
public String dirName="C:\\image";
ByteArrayOutputStream baos=new ByteArrayOutputStream(1000);
BufferedImage img=ImageIO.read(new File(dirName,"red.jpg"));
ImageIO.write(img, "jpg", baos);
baos.flush();
byte[] resultimage=baos.toByteArray();
baos.close();
Then i tried to convert this byte array to a string
String str=new String(resultimage);
byte[] b=str.getBytes();
This much worked fine. But when i reversed this process to re-create the image from that string. i found the image distroted.
BufferedImage imag=ImageIO.read(new ByteArrayInputStream(b));
ImageIO.write(imag, "jpg", new File(dirName,"snap.jpg"));
I got this snap.jpg as distroted.
Please help me i have to convert the image to a string and again i have to re-create the image from that string.To conver the bytearray to string use base64.encoding
String base64String= Base64.encode(baos.toByteArray());
To convert back use Base64.decode;
byte[] bytearray = Base64.decode(base64String);
BufferedImage imag=ImageIO.read(bytearray); -

Array access notation with strings?
I may be confused, but I thought you could use array access
notation with strings. Can someone tell me why this code doesn't
work (or suggest new code):
the code is meant to rewrite the block of text in tText at a
rate of one character per frame... (when the function is called
once per frame) but it doesn't work.DZ-015,
> I may be confused, but I thought you could use

It's made for objects, actually. The array access operator,
[], allows
you to access elements from an Array instance and also lets
you access
properties from any sort of object. The "trick" it provides,
in this latter
case, is that you can refer to these properties -- within the
brackets --
with strings, so it's often used to reference objects
dynamically.
> var sWorkingText:String = tText.text;
Here you've declared a String variable and set it to the
TextField.text
property of some textfield. So far, so good.
> var sNewText:String = oPhotoText[sPageFocus];
Here, you've declared a String variable, but it seems that
you're
setting it to a property of the oPhotoText object. That's now
how this
works.
The array access operator allows you to *use* strings to get
at an
object's properties:
// functionally equivalent
someObject.property1
someObject["property" + 1];
var x:Number = 1;
someObject["property" + x];
Does that help?

Help with Sample on Converting an XML string to a byte stream
Hello All,<br /><br />I am sure this is something simple, but I am just not figuring it out right now.<br /><br />I am following the sample - "Converting an XML string to a byte stream" from the developer guide since I want to prepopulate just 1 field in my PDF form.<br /><br />How do I reference my form field within my servlet code properly??<br /><br />I have tried a few things now, my field is within a subform, so I thought it would be <root><subformName><fieldname>My data</fieldname></subformName></root> I have also tried adding <page1> in there too.<br /><br />I am following everything else exactly as given in the sample code.<br /><br />I do have an embedded schema within the form and the field is bound.<br /><br />Thanks,<br />Jennifer
Well, if you have a schema defined in the form, then the hierarchy of your data must match what is described in the schema. So, can't really tell you what it would look like, but just follow your schema.

While developing and profiling a batch data-analysis program, I found that the "Read From Spreadsheet File.vi" function was where the majority ofthe execution time was spent. Digging further, I found the time was spent in the "Spreadsheet String To Array" function. Obviously I cannot look inside this function, but I wondered if I can somehow speed it up. Attached is a Vi that illustrates what I came up with as an alternative.
Basically using "Spreadsheet String To Array" only to split it up to a 2D String Array, and then "Fract/Exp String to Number" to convert the strings to numbers.
It consistently runs in just over 60% of the time of using Spreadsheet String To Array on it's own to do the conversion.
I am curious as to why using the two functions is quicker than just the one on it's own? Perhaps NI can improve the internals a bit? Or perhaps it is not a fair comparison?

Speed Test Spreadsheet String to Array.vi 26 KBAdding a couple of other conversions to test against i noticed that:
1. Scan from string through a double loop was the slowest
2. Scan Value was slightly faster
3. Direct conversion through Spreadsheet to array as in OP
4. 2-step convert through Fract/Exp.
Could it be that Spreadsheet to array uses Scan Value internally?

Hello All,
I have a small coding challenge that has been whipping me all day. I have a 19 element boolean array that I would like to convert to a string without delimiters("0000000000000000000"). Within a for loop I use a "Select" followed by a "Number To Decimal String." Once outside the loop then use the "Array To Spreadsheet String" function on the indexed output. I tried using a blank delimiter input on the "Array To Spreadsheet String" function but that reverts back to tabs. Bummer. I'll keep plugging away trying different functions and constructs, but this feels harder than it really should be. Any fresh prespectives would be greatly appreciated!
Sincerely,
Zach

LabVIEW, programming like it should be!smercurio_fc wrote:
This has been a known issue for a LONG time. Technically, it's not a bug since the behavior of the function is correct based on its design. It uses a default value of a tab if it receives an empty string. It's no different than with VIs having a default value for a control.
I disagree with that. Our own VIs behave like that since we don't know if anything is wired to a terminal or not. But many LV primitives work differently if you wire something or not. Index Array for 2D or higher dimension arrays for instance works differently when wiring a 0 (default value) or leaving the terminal unwired.
So I would expect the primitive to accept an empty string. -
Combining string array elements into one string
Right, I have an string array called str which stores 1 character in each of its 16 elements. It gets this character from another array, strArray. Now, what I want to be able to do is to take all 16 elements and combine them into one string called keyString. Using the code below keyString only prints out the last character. The code is shown below:
for (x=0; x<16; x++) {
str = new String[16];
str[x] = "";
str[x] += (strArray[(index+x)%16].charAt(strChar[x]));
keyString = str[x];
System.out.print(keyString);
}Any help would be very much appreciated.
Edited by: Paragon96 on May 20, 2008 7:32 AMyour logic is wrong ; if you want to concatenate the content of the array, you have to loop (what you did), and concatenate keyString for each index, meaning:
keyString += str[x];you can also use a StringBuilder for such kind of operations -
Array to Spreadshee​t String VI truncating my rows
I'm using Labview 8.0.
In my VI I am feeding the "Array to Spreadsheet String" VI an array of strings that are in the following format.
7/09/2010 7:43:23.27472 95.284953
7/09/2010 7:43:23.27572 95.284953

7/09/2010 7:43:23.27772 95.284953
The first entry is the data, then time, then data.
The problem I am having is that when I pass this array of strings through the "Array to Spreadsheet String" VI it cuts off the entries and I get the following:
07/
07/
07/
07/
The format I feed to the VI is <%s> for string. Any help would be great. Thanks!

Problem converting U8 array to date-time string
Hi All,
How can I convert U8 array (time_t data type from C dll) to date time string?
A dll function that I am calling has a structure of string, integer and time_t as one of the parameters. Instead of passing cluster, I pass an array of U8 of the size that the structure should be. All the members of the strcuture and parsed correctly except the date/time.
Function Parameter:
typedef struct {
Int AlarmState ;
Int AlarmGrade ;
TCHAR AlarmMessage [100] ;
time_t AlarmTimeStamp ;
} WV_ALARM_INFO ;
Total size = 4 + 4 + 100 + 4 = 112
Using Call Library Function, I set the parameter type to Array of U8 and size 112.
After the array is populated when the function is called, I have done the following to interpret date and time.
1) Using Extract Zero Terminated String.VI I converted U8 array (of size 4) to string.
2) Type casted string to integer (I32).
3) Swap bytes
4) Swap Words
5) Format Date/Time String.
Please see the attached screenshot for visual display of the above.
