Hi All,
I have Class library with name and namespace Dipak.DataAccess and within this name space there is class called DataAccess.
I have another class library with name and namespace Dipak.ESchool.Data and within this namespace there is class called StudentData. Now i have added reference of Dipak.DataAccess in Dipak.ESchool.Data and i have added using Dipak.DataAccess statement in StudentData class .
While calling method of Dipak.DataAccess i have to use full name like DataAccess.DataAccess.GetDataSet(),after adding using Dipak.DataAccess statement.
And when i changes namespace from Dipak.ESchool.Data to ESchool.Data i need not to give full name for method call i am able call with classname.methodname, no need to add namespace name.
Can any one explain me why it is so?
And what i need to do for correcting above problem.
<br />
namespace Dipak.DataAccess<br />
{<br />
public class DataAccess;<br />
{<br />
}<br />
using Dipak.DataAccess<br />
using Dipak.ESchool.Common;<br />
<br />
namespace Dipak.ESchool.Data<br />
{<br />
public class StudentData<<br />
{<br />
DataAccess.DataAccess.GetDataSet()<br />
}<br />
}<br />
Thanks
Dipak Thesiya.

Hi,
you have to use the fullname DataAccess.DataAccess.GetDataSet because the compiler doesn't know if you write only one DataAcces what you mean: namespace or class.
I suggest not to use the same name for a class and a namespace. That can cause too much trouble as you see.
Regards
Sebastian
P.S.: What about naming the DataAccess-namespace "DataAccessLayer"?

Thanks for your reply...
I tried using ur solution...it works...
But as far as concept is concerned ....i have included using statement as using Dipak.DataAccess....so at this point compiler will be knowing the clearly that this name space is referenced...what matters if same class name is there in namespace...

What matters is that the M$ coders didn't provide for this scenario. FWIW I agree with you, but the fact remains that we have to work with the tools we have.
If this is the first of VSs little annoyances that you have encountered, then you are a lucky, lucky chap.

thanks buddy..
but as i have mentioned in my problem description that if i changes my namesapce from Dipak.ESchool.Data to only ESchool.Data it works fine.
But with Dipak.ESchool.Data i have to make call like DataAccess.DataAccess.GetDataSet().
As per naming standerds for namespace we follows Compnyname.projectname.namespacename and thats what i have done...
Dipak my compny name....DataAccess and ESchool my Project name ....

Why not disable it after first selection in the ValueChanged event?
If not, then set a flag to true in the same event and let user change date only if the flag is false.

Hi all,
I want to know the better way of filtering Bulk data, pls guide me...
I have two flat files with lakhs of rows having 16 digit numbers.
i want to filter the numbers from first file with second file , resulting in a unique identified numbers.
I am doing it like this.
I am inserting these data into two seperate tables using bulk insert in Mysql.
And then from my web interface iam inputing two flat files, whenever user clicks on filter button
iam querying tables with a select statement using NOT IN sql statement, but it is taking lot of time and even resuling in a connection timeout.
So pls suggest me the best way of doing it.
Thanks in advance.....

In many cases, "NOT IN" takes a lot of time.
If the table has key column, I suggest following steps.
1. Insert key value, to be filtered, into temporary table.
2. Query with "NOT EXISTS" like "select .. from table where not exists ( select ... temporary_table where table.key = temporary_table.key )"

Hi,
I have my project in c# and I have its setup project.
To update my existing clients with latest changes, I require to create a Windows Installer Patch.
I could create a patch with MsiMsp.exe, but however my patch does not update the existing application. Changes are not reflected... I would have missed some configuration or set them wrong
Can anyone help to get one by one steps to create a Windows Installer Patch?
Regards,

I want to know how can I make a c# project excutable so the computer does not need the microst visual studio to open it. just a simple .exe file which can run everywhere.

If you need to run a .Net application(exe file), you do not need Visual Studio. All you need is the .Net Framework. To be sure that the application runs on the computer without .net framework, just ship the framework along with the set up of your application.

Look under Build menu. You can chose Build solution. Or you can go even further. Chose batch build and you can build with and withoud debugging information.
The exe is builded default in [Project Folder]->[Solution Name]->[Project Name]->[Bin] and there you have folders Debug and release.
Not all files are for running.
Ignore every file with:
[ProjectExe].pdb
[ProjectExe].exe.config
[ProjectExe].vshost.exe
[ProjectExe].vshost.exe.config
[ProjectExe].vshost.exe.manifest

At first I want to say that you do not need Visual Studio installed on the target machine to execute any .exe created with MS .NET, you just need the .NET framework installed in the target machine.
Secondly, I really don't think its possible to build such assembly (.exe or .dll) from .NET, cause it actually breaks the fundamental concept of Microsoft .NET platform.

Hello, I have problem reaading XML file using XmlReader. Here is a snipset
StringReader sr = new StringReader(SettingFile);
XmlReaderSettings xrs = new XmlReaderSettings();
xrs.IgnoreWhitespace = true;
xrs.IgnoreComments = true;
XmlReader reader = XmlReader.Create(sr, xrs);
while (reader.Read())
{
}
reader.Close();
sr.Close();
That expection is so funny, because the xml is properly used. or shoud i say even it was created by XmlWriter. Here is what it looks like:
<?xml version="1.0" encoding="utf-8"?>
<Settings>
<!--This file have strict case sensative info. Edit at your own risk!-->
<Profiles>
<profile ID="23867ee9a2044c5d899ae654c17e8def" Name="Test" WorkingPath="">
<Plugins />
</profile>
</Profiles>
</Settings>
this is how i saved that xml.
XmlWriterSettings xws = new XmlWriterSettings();
xws.Encoding = Encoding.UTF8;
xws.Indent = true;
XmlWriter xw = XmlWriter.Create(SettingFile, xws);
This line was shown by Total Commander without encoding
<?xml version="1.0" encoding="utf-8"?
So how shoud i solve this problem? I want to use XmlWriter, because it doesn't cache in memory.
Thanks in advance

I don't think you are supposed to have any characters before the xml version special tag.
|
|
|
|
|
It was created by XmlWriter. Those 3 letters are only poiting that this file was saved with Encoding UTF-8.
Even if i removed them manualy, error still persist
|
|
|
|
|
It looks suspiciously like a unicode BOM but viewed with a non-western charset
And that's allowed
|
|
|
|
|
Dunno, but why use a StringReader?
I prefer to use an XmlDocument for reading (loading) XML.
|
|
|
|
|
XmlDocumont loads entire xml file into memory. However i expect that file woud exed memory limitation with its size
Edit:
Found the problem
XmlReaderSettings xrs = new XmlReaderSettings();
xrs.IgnoreWhitespace = true;
xrs.IgnoreComments = true;
XmlReader reader = XmlReader.Create(SettingFile, xrs);
while (reader.Read())
{
}
As you can see i feed XmlReader its file. I don't know what URI is. But on one forum i sow they put in with the StreamReader. As it turns out, that class didn't read the file at all, but the string. So Reader only got the path to that file instead actual xml file

Hi All!
I want to use this code to copy a changed file to backup folder, i am using
Filesystemwatcher to listen for the change to a file in a test folder in documents, and when a file is changed a copy should end up in backup.
Now when i use File.Copy it copies the file but then gives me an exception saying it allready exists! How can this be when the backup folder was empty?! i checked this out, and if i use File.Move it still complains when it moves the folder to backup, and the says "file does not exist in test!" so copy would be better as it leaves the original where it is, but why the hell does it say it allready exists in backup when it copies it over?? any ideas? im doin the 70-536 course and the "suggested practices" at the end of the chapters just chuck you in the deep end! lol.
//set the FileSystemWatcher properties
fsd.IncludeSubdirectories = true;
fsd.Path = @"C:\Users\Luke\Documents\test";
fsd.NotifyFilter = NotifyFilters.FileName | NotifyFilters.LastWrite;
//add the changed event handler
fsd.Changed += new FileSystemEventHandler(fsd_Changed);
fsd.EnableRaisingEvents = true;
static void fsd_Changed(object sender, FileSystemEventArgs e)
{
//allready exists on first copy!!??
File.Copy(@"C:\Users\Luke\Documents\test\" + e.Name,
@"C:\Users\Luke\Documents\test\Backup\" + "bak" + e.Name);
//moves file and then says "could not find file in test!
File.Move(@"C:\Users\Luke\Documents\test\" + e.Name,
@"C:\Users\Luke\Documents\test\Backup\" + "bak" + e.Name);
}

Why all the white space?
Anyway... have you set a breakpoint at (or just after) the offending line? It is possible for FileSystemWatcher to fire the same event multiple events in a very short space of time. My guess is it may be suceeding the first time, but the event may be immediately being reraised.
