  • CICS web service requestor GET CONTAINER returns neither data nor error

    - by Namhcir
    I am developing a CICS web service requestor application to consume a distributed web service. I used the web services assistant DFHWS2LS to transform the wsdl to copybooks successfully. I have no problem issuing the PUT CONTAINER and INVOKE SERVICE api commands, but when I issue GET CONTAINER I am not receiving any containers or data. No response codes or error messages, but no data. Any ideas on how to debug this would be greatly appreciated. Thanks,

  • Scraping Google docs (can't use API)

    - by Andy Waite
    I'm building an iPhone app which needs a peice of meta data from a user's Google Spreadsheet. Unfortunately the meta data I need is not exposed by the API, so I will need to scrape it from the document's HTML source (it would not be present in any of the exported variants). Is there anyway to include authentication parameters in a call such as: http://spreadsheets.google.com/ccc?key=abc123&username=...&password=...

  • fread and fwrite are not recommended for use with structured data

    - by forest58
    A book beginning linux programming 3ed says "Note that fread and fwrite are not recommended for use with structured data.Part of the problem is that files written with fwrite are potentially nonportable between different machines." What does that mean exactly? what calls should I use if I want to write a portable structured data reader or writer? direct system calls?

  • Changing Data in ListView

    - by legr3c
    Hi In my app I use a ListView to display data from the database. The data changes sometimes, for example when the user applies new filters or changes the sorting method. I use AsyncTask to get the databsase cursor that points to the new data set because sometimes data needs to be loaded from the net which can take some time. What I do now looks something like this: private class updateTask extends AsyncTask<Void, Void, Void> { /* * runs on the UI thread before doInBackground */ @Override protected void onPreExecute(){ // prepare some stuff... } /* * runs in a separate thread * used for time-consuming loading operation */ @Override protected Void doInBackground() { //get new database cursor mCursor = mDbAdapter.getCursor(); return null; } /* * runs on the UI thread after doInBackground */ @Override protected void onPostExecute(Void result){ if(mCursor!=null){ MyActivity.this.startManagingCursor(mCursor); mCursorAdapter = new MyCustomCursorAdapter(MyActivity.this, mCursor); mListView.setAdapter(mCursorAdapter); } } } This works so far but I realize that creating a new CursorAdapter and calling setAdapter on my ListView each time isn't the correct way to do it. Also, after setAdapter the scroll position of the list is set back to the top. I found this post which describes how to do it properly. So now I want to do something like this: onCreate(){ // ... // create the CursorAdapter using null as the initial cursor MyCustomCursorAdapter cursorAdapter = new MyCustomCursorAdapter(this, null); mListView.setAdapter(cursorAdapter); // ... } private class updateTask extends AsyncTask<Void, Void, Void> { /* * runs on the UI thread before doInBackground */ @Override protected void onPreExecute(){ // prepare some stuff... } /* * runs in a separate thread * used for time-consuming loading operation */ @Override protected Void doInBackground() { //get new database cursor mCursor = mDbAdapter.getCursor(); return null; } /* * runs on the UI thread after doInBackground */ @Override protected void onPostExecute(Void result){ // this returns null! MyCustomCursorAdapter cursorAdapter = (MyCustomCursorAdapter)mListView.getAdapter(); Cursor oldCursor = cursorAdapter.getCursor(); if(oldCursor!=null){ MyActivity.this.stopManagingCursor(oldCursor); oldCursor.close(); } if(mCursor!=null){ MyActivity.this.startManagingCursor(mCursor); cursorAdapter.changeCursor(mCursor); } } } This however doesn't work for me because (MyCustomCursorAdapter)mListView.getAdapter(); always returns null. Why does this happen? What am I doing wrong? Edit: Some additional information: my adapter implements SectionIndexer. I don't really think that this has anything to do with my problem but it has caused me some troubles before so I thought I'd mention it.

  • Microformat combination to use with events data on a map

    - by Dave Taylor
    I have event data displaying on a map and I am currently using the geo microformat alongside it however it's not particularly rich to have just a list of locations without any details of what they correspond to. I've been looking at combining microformats to achieve this and looking for some thoughts on the subject here is the data i am marking up: event title, event location [latlong], event address, contact phone, link to full details My initial thoughts are to use an hCard along with geo? Is there anything better? Thanks in advance

    - by Rob Young
    Has anyone written a YQL open data table for accessing Wikipedia? I've had a hunt around the internet and found mention of people using YQL for extracting various bits of information from Wikipedia pages such as microformats, links or content but I haven't been able to find an open data table that ties it all together.

  • how could I store data within a GUID

    - by Mark
    I have an application that I want to represent a users session (just small pieces of data here and there) within a GUID. Its a 16 HEX characters (so 16^16 possible values) string and I want to 'encode' some data within that GUID. How can I achieve this? I am really after any ideas and implementations here, Ive not yet decided on the best mechanism for it yet. I would also like encryption to be involved if possible... Thanks a lot Mark

  • Type mismatch: cannot convert from ArrayList<Data> to MyCollection

    - by Tommy
    I've read similar questions here but I'm still a little confused. MyCollection extends ArrayList<MyClass> MyClass implements Data yet this gives me the "cannot convert from ArrayList to MyCollection" MyCollection mycollection = somehandler.getCollection(); where getCollection looks like this public ArrayList<Data> getCollection() So my assumptions are obviously wrong. How can I make this work like I would like it to

  • Writing csv header removes data from numpy array written below

    - by user338095
    I'm trying to export data to a csv file. It should contain a header (from datastack) and restacked arrays with my data (from datastack). One line in datastack has the same length as dataset. The code below works but it removes parts of the first line from datastack. Any ideas why that could be? s = ','.join(itertools.chain(dataset)) + '\n' newfile = 'export.csv' f = open(newfile,'w') f.write(s) numpy.savetxt(newfile, (numpy.transpose(datastack)), delimiter=', ') f.close()

    I am running Ruby 1.9.

  • Paginating data, has to be a better way

    - by John Tyler
    I've read like 10 or so "tutorials", and they all involve the same thing: Pull a count of the data set Pull the relevant data set (LIMIT, OFFSET) IE: SELECT COUNT(*) FROM table WHERE something = ? SELECT * FROM table WHERE something =? LIMIT ? offset ?` Two very similar queries, no? There has to be a better way to do this, my dataset is 600,000+ rows and already sluggish (results are determined by over 30 where clauses, and vary from user to user, but are properly indexed of course).

  • Tracking down data load performance issues in SSIS package

    - by SteveC
    Are there any ways to determine what the differences in databases are that affect a SSIS package load performance ? I've got a package which loads and does various bits of processing on ~100k records on my laptop database in about 5 minutes Try the same package and same data on the test server, which is a reasonable box in both CPU and memory, and it's still running ... about 1 hour so far :-( Checked the package with a small set of data, and it ran through Ok
