Reading data from App Web List and Displaying in HostWeb.

Hi,
Is it possible to read list data from AppWeb and display it on a page in HostWeb?
Any approaches to achieve this?
Regards,
Rivin Jose.

Hi Rivin,
There seems no need to query an app web from host web cause App for SharePoint is designed to work as an “advanced web part” solution, it should work as a separate
component of a SharePoint site which shouldn’t be taken care on the host web side.
If you simply want to display data from app web in the host web, add an App Part into a page in the host web would be the best option for you as what Dan suggests.
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 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.

Possible to read data from a web browser into java?

Is it possible to read data from a web browser such as IE or Mozilla into a java applet for use and manipulation? If it is, could someone please post some documentation I could look at or a snip-it of code I could use? Thanks.

This will read the content from a site:
import java.net.*;
import java.io.*;
class Test {
     public static void main(String[] argv) throws Exception {
          URL u = new URL("http://www.google.com");
          URLConnection uc = u.openConnection();
          BufferedReader br = new BufferedReader(new InputStreamReader(uc.getInputStream()));
          String text;
          while( (text = br.readLine()) != null ) {
               System.out.println(text);
}

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?

HI Guys,
I found my solution by myself. Below is the solution , hope this will help others:-
Retrieve data from MDM using MDM ABAP API.

Can Oracle Portal read data from an access DB and loaded it an Oracle DB?

Hi All.
Does Oracle Portal provides a portlet to read data from an access db so that i can transfer it to my Oracle DB?.
I believe Application Express does that .... Any portlet maybe ...?
Regards, Luis ...!

There are portlets that read from a DB to make reports, you can try to create a form portlet so you can make inputs to the database, no buil-in like you wish, has to be done manually.

Shell scripts to read data from a text file and to load it into a table

Hi All,
I have a text file consisting of rows and columns as follows,
GEF001 000093625 MKL002510 000001 000000 000000 000000 000000 000000 000001

the whole application is deployed in unix and that text file comes from mainframe. am working in the unix side of the application and i cant access the data directly from the mainframe. so am required to write a script which reads the data from text file which is placed in certain location and i have to load it to oracle database.
so I can't use SQL * loader.
Please help me something with this...
Thanks in advance.

1. Create a dictionary object in Oracle and assign it to the folder where your file resides
2. Write a little procedure which opens the file in the newly created directory object using ULT_FILE and inside the FOR LOOP and do INSERTs to table you want
3. Create a shell script and call that procedure

How to properly read data from one DAQ-assistant and write simultaneously with another DAQ-assistant (which is inside a loop)

Hello.
I'm a newbie working on my Master's thesis conserning a project that is based on old G-code made by another newbie so bear with me.
I need to create a sequance of output controls. For this I'm using a for loop that eventually creates two triangular ramps during a period of 90 seconds. I've confirmed that this function works properly by measuring the actual output of the DAQ-decice (NI USB 6353).
The problem is the following: During this controll-cycle I need to simultanously collect data from the same DAQ-device. At this point there is only one DAQ-assistant output-block in the main loop of the program and all the signals are derived from it to where they are needed.There is a case-structure (the bottom case structure in the picture) that contains the functions needed to collect the data during the test cycle. However these two actions, outputting data and inputting data, are not synchronized in any way which may be the reason why I get the 200279 error or alternatively the 200284 error during the test cycle. I've tried changing the sample rate, buffer size and the timeout time as adviced but nothing seems to help.
What would be the simplest way to solve this problem?
Help is greatly appreciated!

Thanks for quick reply.
However, I did try it (see the picture) but I still have a problem: I only get 100 samples / channel during the test sequence (all from the first seconds of the sequence) in total even though I've set the data aqcuiring DAQ-assistant as "continous" and "samples to read = 95k" and rate is 1000Hz.
Edit.
And lastly, I have trouble adding this "extra" DAQ-assistant to the vi. because I get an error about a resource (The 6353) being reserved, even though I connected a false constant to the "STOP" -input of the main DAQ-assistant.

Can a field be made to pull the current date from computer or internet and display it?

Im making a form for someone and they want the current date of when the form is opened to be displayed at the top without having to type it in. Is this possible? I assume this has something to do with javascript but I dont know anything about that stuff

Hi,
I search something in the forum and found your message. If you need it once again, try this:
var f = this.getField("currentDate");
f.value = util.printd("dd.mm.yyyy",new Date());
Or this one (helpful for Germans who want to display their date like this: 29. Juni 2010. If you take the first one in the dd. mmmm yyyy format, it shows you the month in English. 29. June 2010):
var f = this.getField("currentDate");
f.value = util.printd("date(de){DD. MMMM YYYY}", new Date(), true);
