Need some samples to make Entity framework interact with WPF

HI guys,
I need to create an app which will query all details about customer from very big database for different search crieria. I don't have any sp to call individual section details of customer. so i planned to go with Entity framework and WPF. Both are new to
me.
Could someone please help me with creating good WPF application (beautiful look and feel) & entity framework interaction with DB?
or any other to make this requirement in an easy way with latest technologies.. All i need some good UI for searching customer details..
thanks in advance
Regards

I (obviously) agree my sample is something to look at.
Since it's the first in a series rather than a complete guide it cuts a number of corners.
One to emphasise is that I almost never allow a user to edit in a datagrid directly.
I either use popups so they are forced to work on one record at a time.
Or I have a different usercontrol for a particular task a user does - like raising an order say.
The second in the series is on the way. Not sure when exactly but next month. I have the code ready but I've not written the article for it yet. Depending on your timescales you might find that useful.
Also read this:
http://social.technet.microsoft.com/wiki/contents/articles/26673.wpf-collectionview-tips.aspx
That explains some dynamic filtering on the client and touches on a way to haul bits of a HUGE set of data onto the client.
You definitely don't want to do that all at once.
The thing to emphasis is you should always be looking to give the user a subset to look at.
Think in terms of a maximum of 200 to 300 records at a time in a datagrid.
Linq with EF offers pass through queries.
You will almost certainly want to use that feature in order to pick all the customers starting with the letter A or in town xyz or whatever.
You use linq on the client and it is turned into sql on the database.
One thing which is sort of odd about linq is that the sql is generated when you iterate a collection. That has an odd benefit which is great for flexible querying.
You can base one linq query on another and chain your various criteria together.
That only generates sql when you use that end result.
Hope that helps.

Need some help: my itunes won't sync with my iphone anymore. Both softwares are up to date and I've reinstalled itunes. After I reinstall, it syncs. But then when I reboot my computer, it no longer syncs anymore and I have to keep reinstalling itunes. Thoughts???

thought that it was possible to have the same iTunes library on any machine that was authorised, a kind of cloud-iTunes I guess.
That would convenient, but sadly it is not the case. Sorry!
Either way your welcome and best of luck!

Calling Oracle stored procedure with out param of user define type from Entity Framework 5 with code first

Guys i am using Entity Framework 5 code first (I am not using edmx) with Oracle and all works good, Now i am trying to get data from stored procedure which is under package but stored procedure have out param which is user define type, Now my question is
how i will call stored procedure from entity framework
Thanks in advance.

I agree with you, but issue is we have lots of existing store procedure, which we need to call where damn required. I am sure those will be few but still i need to find out.
If you think you are going to get existing MS Stored Procedures or Oracle Packages that had nothing to do with the ORM previously to work that are not geared to do simple CRUD operations with the ORM and the database tables, you have a rude awakening
coming that's for sure. You had better look into using ADO.NET and Oracle Command objects and call those Oracle Packages by those means and use a datareader.
You could use the EF backdoor, call Oracle Command object and use the Packages, if that's even possible, just like you can use MS SQL Server Stored Procedures or in-line T-SQL via the EF backdoor.
That's about your best shot.

Unzipping files - works, but need some hlp to make it better

Hi there!
I am trying to unzip files using java.util.zip
My code works If I have a parent directory for all files/folders.
So when I unzip the structure is as -
zipFileName -> parent folder -> child files/folders
where, zipFileName and parent folder names are same.
But I want to have it as
parent folder -> child files/folders.
Here is my code :
public void unzipFiles(String zipFileName, String zipFolderPath, String unzipPath) {
Enumeration entries;
ZipFile zipFile;
try {
//Set up a directory name for the unzipped files
String courseFolderName = zipFileName.substring(0, zipFileName.indexOf("."));
//Get the zip file from its location in the "zip" folder on theServer
String separator = File.separator;
zipFile = new ZipFile(zipFolderPath + separator + zipFileName);
//Set up the directories in the data store
entries = zipFile.entries();
while (entries.hasMoreElements()) {
ZipEntry entry = (ZipEntry)entries.nextElement();
if (entry.isDirectory())
String dir = entry.getName();
System.out.println("entry :"+unzipPath + separator + courseFolderName + separator + dir);
checkFilePath(unzipPath + separator + courseFolderName + separator + dir);
unzippedFolders.addElement(courseFolderName + separator + dir);
//Add the unzipped files to the data store
entries = zipFile.entries();
while (entries.hasMoreElements()) {
ZipEntry entry = (ZipEntry)entries.nextElement();
if (entry.isDirectory())
continue;
if (debug)
System.out.println("Extracting file: " + entry.getName());
copyInputStream(zipFile.getInputStream(entry),
new BufferedOutputStream(
new FileOutputStream(unzipPath + separator + courseFolderName + separator + entry.getName())));
zipFile.close();
catch (IOException e) {
e.printStackTrace();
catch (Exception e) {
e.printStackTrace();
[\code]
The above code works if the zip file is having all files under a parent folder:
zipFileName -> parent folder -> child files/folders
sample output:
unzipping the files...
entry :C:\DataStore\template\test2/IMAGES/
Creating directory C:\DataStore\template\test2/IMAGES/
entry :C:\DataStore\template\test2/INPUTS/
Creating directory C:\DataStore\template\test2/INPUTS/
otheriwse, if I have no levels under my zip level, I get an error like this:
unzipping the files...
Extracting file: schedule.htm
Extracting file: IMAGES/AMTC.GIF
java.io.FileNotFoundException: C:\DataStore\schedule\IMAGES/AMTC.GIF (The system
cannot find the path specified)
Can somebody pls help me find out where I am going wrong. Any help would be really really great.
Thanks
-Mahi

I don't know if this will help but... If I understand correctly, is not
recreating the correct directory tree?
// unjar the jar to the destination directory destdir
// destdir = c:\mydir\ is prepended to each jar entry
JarFile jarFile = new JarFile( "myjar.jar" );
Enumeration e = jarFile.entries();
while( e.hasMoreElements() )
JarEntry entry = (JarEntry)e.nextElement();
File localFile = new File( destdir + entry.getName() );
---> // peel off the parent path and make as directories
---> File directory = new File( localFile.getParent() );
---> directory.mkdirs();
// these can be inlined if desired
FileOutputStream fileOutputStream = new FileOutputStream( localFile );
BufferedOutputStream bufferedOutputStream = new BufferedOutputStream( fileOutputStream );
copyInputStream( jarFile.getInputStream( entry ), bufferedOutputStream );
jarFile.close();
