Fetch NOAA weather GIF file and display thru LabView

I have an application that requires fetching real-time radar weather data from the NOAA weather site every 60 seconds and displaying it in LabView. I am using the Datasocket VI set, and have been able to fetch HTML (ASCII) data successfully and write it to a file using the Write Binary File VI, but when I go directly to fetching the .gif file, no data is fetched. I suspect that the Write Binary File VI is having trouble with the binary data in the .gif file itself. Occasionally I can get a few bytes of data, but it seems to stop on zeros. Has anyone been able to do something similar to this? The URL containing the .gif is at http://www.wrh.noaa.gov/radar/images/DS.p19r0/SI.kesx/latest.gif

Hello Doug1234,
I have attached an example that demonstrates how to do this in LabVIEW with Datasocket. It works by defining the web page as text and then reading the data into a string. Once read, we can save the string to file with a .gif extension.
As mentioned by Evan, the internet toolkit will be the easiest way to perform this operation.
Good luck with the development.

How to edit a Animated Gif file and convert to SWF

I am using the creative cloud with fireworks. I chose the free trial with buying in mind if I saw it work properly. I simply want to upload an animated GIF file and then download it as a SWF file. I saw someone on youtube do this and it's not that if I get on the correct page I would not know how to do that but I just cannot find how to get the GIF into the software to edit. It has just simply put them in the creative cloud folder which can open them on IE> How do i make it available to edit and convert to SWF please? Thanks in advance.

The problem is in the delimiters in your text file. By default, Read From Spreadsheet File.vi expects a tab delimited file. You can specify a delimiter (like a space), but Read From Spreadsheet File.vi has a problem with repeated delimiters: if you specify a single space as a delimiter and Read From Spreadsheet File.vi finds two spaces back-to-back, it stops reading that line. Your file (as I got it from your earlier post) is delimited by 4 spaces.
Here are some of your choices to fix your problem.
1. Change the source file to a tab delimited file. Your VI will then run as is.
2. Change the source file to be delimited by a single space (rather than 4), then wire a string constant containing one space to the delimiter input of Read From Spreadsheet File.vi.
3. Wire a string constant containing 4 spaces to the delimiter input of Read From Spreadsheet File.vi. Then your text file will run as is.
Depending on where your text file comes from (see more comments below), I'd vote for choice 1: a tab delimited text file. It's the most common text output of spreadsheet programs.
Comments for choices 1 and 2: Where does the text file come from? Is it automatically generated or manually generated? Will it be generated multiple times or just once? If it's manually generated or generated just once, you can use any text editor to change 4 spaces to a tab or to a single space. Note: if you want to change it to a tab delimited file, you can't enter a tab directly into a box in the search & replace dialog of many programs like notepad, but you can do a cut and paste. Before you start your search and replace (just in the text window of the editor), press tab. A tab character will be entered. Press Shift-LeftArrow (not Backspace) to highlight the tab character. Press Ctrl-X to cut the tab character. Start your search and replace (Ctrl-H in notepad in Windows 2000). Click into the Find What box. Enter four spaces. Click into the Replace With box. Press Ctrl-V to paste the tab character. And another thing: older versions of notepad don't have search and replace. Use any editor or word processor that does.

I need to read data from a text file and display it in a datagrid.how can this be done..please help

hey ppl
i have a datagrid in my form.i need to read input(fields..sort of a database) from a text file and display its contents in the datagrid.
how can this be done.. and also after every few seconds reading event should be re executed.. and that the contents of the datagrid will keep changing as per the changes in the file...
please help as this is urgent and important.. if possible please provide me with an example code as i am completely new to flex...
thanks.....

It's not possible to read from a file without using classes from the core API*. You'll have to get clarification from your instructor as to which classes are and are not allowed.

*Unless you write a bunch of JNI code to replicate what the java.io classes are doing.

The below is the code I have tried so far.
// .Reading a CSV
var reader = new StreamReader(File.OpenRead(@"D:\Users\RajaVill\Desktop\C#\input.csv"));
List<string> listA = new List<string>();
while (!reader.EndOfStream)
var line = reader.ReadLine();
string[] values = line.Split(',');
listA.Add(values[0]);
listA.Add(values[1]);
listA.Add(values[2]);
// listB.Add(values[1]);
foreach (string str in listA)
//StreamWriter writer = new StreamWriter(File.OpenWrite(@"D:\\suman.txt"));

Very simple example:
var column1 = new List<string>();
var column2 = new List<string>();
using (var rd = new StreamReader("filename.csv"))
while (!rd.EndOfStream)
var splits = rd.ReadLine().Split(';');
column1.Add(splits[0]);
column2.Add(splits[1]);
// print column1
Console.WriteLine("Column 1:");
foreach (var element in column1)
Console.WriteLine(element);
// print column2
Console.WriteLine("Column 2:");
foreach (var element in column2)
Console.WriteLine(element);

Reading from a text file and displaying the contents with in a frame

Hi All,
I am trying to read some data from a text file and display it on a AWT Frame. The contents of the text file are as follows:
pcode1,pname1,price1,sname1,
pcode2,pname2,price2,sname1,
I am writing a method to read the contents from a text file and store them into a string by using FileInputStream and InputStreamReader.
Now I am dividing the string(which has the contents of the text file) into tokens using the StringTokenizer class. The method is as show below
void ReadTextFile()
                    FileInputStream fis=new FileInputStream(new File("nieman.txt"));
                     InputStreamReader isr=new InputStreamReader(fis);
                     char[] buf=new char[1024];
                     isr.read(buf,0,1024);
                     fstr=new String(buf);
                     String Tokenizer st=new StringTokenizer(fstr,",");
                     while(st.hasMoreTokens())
                                      pcode1=st.nextToken();
                           pname1=st.nextToken();
          price1=st.nextToken();
                          sname1=st.nextToken();
     } //close of while loop
                } //close of methodHere goes my problem: I am unable to display the values of pcode1,pname1,price1,sname1 when I am trying to access them from outside the ReadTextFile method as they are storing "null" values . I want to create a persistent string variable so that I can access the contents of the string variable from anywhere with in the java file. Please provide your comments for this problem as early as possible.
Thanks in advance.

If pcode1,pname1,price1,sname1 are global variables, which I assume they are, then simply put the word static in front of them. That way, any class in your file can access those values by simply using this notation:
MyClassName.pcode1;
MyClassName.pname1;
MyClassName.price1;
MyClassName.sname1

Can a servlet read a jsp file and display its contents?

Hi,
I would like to know if Servlets can read a Jsp file and display its contents.. Right now for our website, I am using a html file to be displayed after a successful post operation through the Servlets...
-Thanks!

I posted this in another thread.
Here's some code that reads using a URL. This doesn't work with JSPs as the server executes JSP when it connects but it's useful for other file types. Note that the filename is a URI</h1>This is <code>show.jsp</code></h1>
<hr>
<%! String file = null; %>
<%! java.io.InputStream is = null; %>
<%
file = request.getParameterValues("filename")[0];
try {
is = (new java.net.URL(file)).openStream();
} catch (java.io.IOException ioe) { out.write(file + " not found!<br>"); }
java.io.BufferedReader in = new java.io.BufferedReader(new java.io.InputStreamReader(is));
String line = "";
%>
<pre>
<%
while((line = in.readLine()) != null) {
%>
<%=line%>
<%
%>
</pre>

There are so many things wrong with this VI, I'm not even sure where to start.
Hard-coding paths that point to your user folder on the block diagram. What if somebody else tries to run it? They'll get an error. What if somebody tries to run this on Windows 7? They'll get an error. What if somebody tries to run this on a Mac or Linux? They'll get an error.
Not using Read From Spreadsheet File.
Use of local variables to populate an array.
Cannot insert values into an empty array.
What if there's a line missing from the text file? Now your data will not line up. Your case structure does handle this.
Also, how does this answer the poster's question?

Include text file and display from text file

Ok. I'm found the site with the monkey on the the flash thing and all it shows is a name, email and something else and I used it and it works by including a txt file and displaying text from that file as putting down this information
name.text = this.name;
and I can't find the site anymore to get help.
I want to know how to include a PHP script that shows this information like this
text=something I need&username=My Name&email=[email protected]
I want to show this stuff on the flash but every time I execute by using it as localhost/test.php, it will show a sentax error.
This is really stressing me out and I need a lot of help on this stuff.
Can someone help me?

ok. let me describe something else.
there's 3 text boxes that is dynamic text.
one of them is called name
the other one is called email
and last one is called location
in the text file, it shows this for importing to the flash file
name=My Name&email=EMAIL&location=My Location
When viewing the flash file that you created, it shows the name, it shows the email, and it shows location.
When I do it on my own even with a text file, it keeps on saying that there is an error on line 1.
I found a site that shows how to do it and it shows what to put in a text file, and it shows the action script. On the FLA file that he shows me has a monkey on the flash file and it has 3 text boxes that I described above. As well as the text file, it is the same. I used the example and it worked but I can't find the example again. I don't know what happened to the website and I don't know what happened to the download I had but it is not downloaded any more. I have adanced systemcare pro so it clears out my recent web searches and my recent downloads so I can't find it. I did a google search on anything about action scripts. I even did a monkey action script search and I couldn't find it.
It's making me mad and I don't know what to do. This is stressing me out way more than you think.
UPDATE:
I did a google search on a file I found in my www folder and I found it. finally.
Here's the site.

Upload excel file and display content in sapui5 table

hi:all
how to upload excel files and display its contents in the view of sapui5 table ,then 'create ' these data into the abap database using odataservice.
Do you have any solutions ? I appreciate for your help.

Two possible way come to mind.
1. ADF DI (desktop integration): sorry, don't know enough about it to give a how to :-(
2. POI (http://poi.apache.org/) : open source project to read and write excel file with java. Using POI you can open the .xsl file, read it's contents and display it as af:table. For this you need to read the xsl into a data structure (this can be a temporary db table or a list of POJOs) and build a data control out of it. This you can drop on a page as table.

Parsing large xml file and display using swing

Hi all,
I want to read a large xml file and display graphically in swing as a tree structure.
I implemented it and works fine for files of 5MB size after increasing the jvm heap size (-Xmx). If the file size is larger than 5MB it throws out of memory error. I'm creating a custom datastructure from the xml and I'm using sax parsing.
After displaying the datastructure, the user could do some operation on this, like search etc.
Can any of you suggest a method, to support larger files ? What I'm looking for is create the datastructure in file system, rather than in memory.
Any other tips for memory management would be greatly appreciated
Thanks in Advance.
