Hi undead,
Your question is not proper.
However Where IList Interface is Implemented weather explicitly u r implementing? if yes, If Add method is implemented in your class, take for each loop and with IList.IndexOf(i)store in a DataSet.
Still you not get my answer, give detail question & requirement.
bye

Thanks with your help. I'm sorry that I didn't give u detail question & requirement.
I used Oject.Net to get data from a database to an IList (function PersistenceManager.getAllObjectsFromDb(typeof(Student));)
public class Student
{
int m_StudentId;
string m_Name;
string m_Email;
....
}
When I run, it will return an IList containing an array of Student object. After that I bind this IList to a datagrid, it's OK, but I don't know how to sort data in this IList (ex : m_Name DESC) so that I want to change it to a datatable (or dataset) to use the dataview to sort data.
How to do that???

Hi there!
After build my project it runs on my computer without problems. After installing that on my laptop it doesnt work.
The application uses 2 dlls coded in c++. when the application starts, it cant access the dlls.
http://msdn2.microsoft.com/en-us/library/ms235317.aspx --> desribes a workaround
I have to set a PATH environment variable in System-Advanced-Environment Variable under Windows XP.
But I have no idea how to make it with an *.bat file.
Is it possible to place the path variable in the registry?

In your installation project, open the Registry view and add your custom values as children to the "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" key.
NOTE: As always, you assume risk when changing the registry. Doing so can cause your system to become unstable or unusable. Please, do so at you own risk.

I have a problem,
i build an aspx page a normal webform, on this i use a control from somewhere deep in the internet, it looks like a textbox, but has a small calendar attached, doesnt matter, works fine. The Problem is, that textbox has no 'TextChanged' Event, but i really need this one.
So my question is, could anybody help me, how to add this event to this custom TextBox, means how to add an event which is fired when the text in this box is changed!
Or in general how to create new events for existing controls/classes or whatever, damn .NET!
Hope someone is genius on that and can help me out soon,
looking forward not to kill myself

how to create/extend the some of the standard controls like radio buttons / check boxes to make them more touch screen friendly.
It would be helpful if you can provide the options as early as possible
Thanks

Do you just want larger targets for the touch screen? If so, just change their Height and Width properties to affect that. Ensure that the larger controls do not overlap.

I'm running beta 2, and there is a testing framework(?) built into it. Check out the (would you have guessed it?) Test menu.
Cheers,

Hi.
I need a sample code that using it I can first delete all records in database (make database empty), then insert one row in it.
my database is Access, and languge C#.
Please help me in this context with complete code.
Thank's very much.
Best wishes

Well, at least you said please!
1) You give no details of the database tables, the table you want to insert into or any evidence that you have tried this yourself.
2) You EXPECT complete code? You will find a number of people here charge a good daily rate for coding, others are hobbyists who also give alot of time to a community such as CP. However, almost everyone is prepared to answer questions if the person shows SOME initiative (even a little). In your case there was ZERO!
3) Read How to get answers to your questions[^]
And if you were ever in any doubt - Notice a pattern in this posters questions?[^]

I've got an interesting Error on a recent program i've written that i am hoping someone could shed some light on.
My program at the moment consists of a main form and 2 word document programs written using vsto the entire things was written and tested in vs team system 2005 now i've written a set up program that essentially installs all the files and then registers the directory the word documents and their dll files are in with caspol.exe now on my computer it works just fine when i test the installation.
however i used my girlfriends computer as another test platform the install went fine she didn't have the .net 2.0 framework so the bootstrap loaded fine and it installed the framework it then proceded to install the app that all ran smooth and quick so i run the program and everything is working as it should.
but as soon as i try to open either of the word documents word gives the following error:
"The assembly * could not be found at or could not be loaded."
and yes that's the whole error message i have no clue where to even start....
if anyone has any ideas please let me know
thanks so much

Ok this is a first for me I'm replying to my own post but i figured it out on my own and i figured it might benefit others so here goes.
Running on a hunch i decided to grab the VSTO runtime from msdn and install it on my girlfriends computer and viola works like a charm.
so i simply added a Process object in my custom installer class to install the VSTO runtime and now the installation works like a charm.
I do however have a side question if anyone cares to help
the file vstor.exe gives a few command line switches one in particular is /Q which it says is for quiet mode for installations now to me that means it runs completely in the background zero user interaction. well even with the /Q switch it still loads it's installation form. if anyone knows how to completely disabble that and still install the runtime it would be much appreciated
Ryan

I just downloaded vstor.exe and have confirmed your dilemma. It seems that the /Q flag does not get passed to the installer. If you want to do this, here's what I recommend:- Run vstor.exe
- When the installer form appears, open Explorer to "%TEMP%\IXP000.TMP"
- Copy all of those files to a "happy" place
- Cancel the installation
- Roll your own installation using those copied files and the command "install.exe /q"
Sometimes, even Microsoft makes mistakes with their installation programs....

Hi,
I want to validate the email address using c#. I dont wnat to user any validator. Is it possible...

As a wise man once said Where does the first link lead you?[^]
So, you can use a regex as the above link will no doubt tell you, that will tell you if the email address is in the correct format.
You could also look for a webservice that will validate an email address as active - google will tell you more.
However, what did you mean by "I dont want to use a Validator"? Is this a web form or a winform?
