A dataset is a collection of datatables. A datatable has a collection of datarows.

I have a simple batch file script here that runs during log on and log off that writes a rolling CSV file of each user and which computer they are on. Just for fun, here's what I am running...
LOG ON SCRIPT:
for /f "Tokens=2 Delims=[]" %%i in ('ping -n 1 "%computername%"') do set IP=%%i
rem The following line creates a rolling log file of usage by workstation
echo Log In: %TIME% %Date% %USERNAME% >>\\lsdnas3\Logs\Computers\%COMPUTERNAME%.log
rem The following line creates a rolling log file of usage by user
echo Log In: %TIME% %Date% %COMPUTERNAME% IP=%IP% >> \\lsdnas3\Logs\Users\%USERNAME%.log
LOG OFF SCRIPT:
for /f "Tokens=2 Delims=[]" %%i in ('ping -n 1 "%computername%"') do set IP=%%i
@rem The fololowing line creates a rolling log file of usage by workstation
@echo Log Off: %TIME% %Date% %USERNAME% >> \\SERVER\Logs\Computers\%COMPUTERNAME%.log
@rem The following line creates a rolling log file of usage by user
@echo Log Off: %TIME% %Date% %COMPUTERNAME% IP=%IP% >> \\SERVER\Logs\Users\%USERNAME%.log
Well, I want to first choose computer or user logs... Got that figured out (duh) but how do I get a dropdown that will list each file so I can open it as a data source and display it? I know how to open and read the files, and all that boring stuff.
I am sure I will figure it out via a bit of research, but I thought asking might help someone else looking for a similar solution in the future.

This won't compile, it's not valid C# code.

Oh I understand... This is a simple batch file for DOS (runs in Windows XP in our domain).
I write a lot of simple asp.net apps so I can use them anywhere in any of our locations... These log files were fabricated because we have a lot of users who bounce around from PC to PC and we want to be able to know where they are when they call or e-mail us.
I am writing an ASP.NET intranet site with C# and want to use C# to display what these batch files created. (I posted them above because I know batch files can be fun).
I thought it would be relevant since it is using a different method (other than C#) to start the process of logging.

For some reason I was expecting a story about cows.

To get a list of files, you can use the [Directory.GetFiles^]. I believe this will work with UNC paths as well as local paths. To read the file as a data source you can look at [this^] article.
Hope that helps.
Tanks for your support

I've started using LINQ to get data out of my SQL DB and it workes fine. I load the data and use databinding to get the data in the grid. The code lools like that:
BudgetDataDataContext _budgetDataContext = new BudgetDataDataContext();
bindingSourceNsc.DataSource = from n in _budgetDataContext.Nscs select n;
gridControlTest.DataSource = this.bindingSourceNsc;
The data is shown in the grid. That's fine. Now the user can change values directly in the grid. I'M chatching the event when the change has been made and want to write the new data to the database (update). The code therefore looks like that:
_budgetDataContext.SubmitChanges(System.Data.Linq.ConflictMode.FailOnFirstConflict);
The problem now is, that the data in the database is not changed. Can anyone give me a hint what I've done wrong?

I'd no expert in Linq-to-SQL, but I'd guess the problem is this:
bindingSourceNsc.DataSource = from n in _budgetDataContext.Nscs select n;
You're essentially saying, "The data source is the result of this query". Since query results are read-only, your changes are getting back into the database.
Have you tried simply:
bindingSourceNsc.DataSource = _budgetDataContext.Nscs;

hi everybody ,
can anyone tell me what reference should i add to use System.Threading.Tasks ?
Thank you !

Are you using VS2010 and .NET 4.0?? If not, it doesn't exist in previous version. Considering neither 2010 or .NET 4.0 is out yet, it's unlikely you're using it.

oh , i see 
I had found a tutorial that was mentioning it , and i though it was already there .
Thank you !

Probably, but it's more rare to come by in the forums.

Hi,
I wanted to know if there is any way to call a method from just clicking a radio button without having to click on an apply button.
Thank you

The Click event may help you here. If you want something more efficient, which isn't called unless the checked value changes, use CheckedChanged or something like that

Hello,
I have developed one application, and added it to right click pop-up menu of the folder.
Whenever user right-clicks on folder and selects my application from pop-up menu, I want the path to that folder (on which user has done right click).
I am using Directory.GetCurrentDirectory(), but it gives me path to the parent directory of the user right clicked directory.
How can I get the path to the directory on which user has done right click?
Regards
Abhishek

Perhaps you could pass the folder name to the application. Presumably, you've added a registry entry in order to allow you to run something from Windows' context menu. Append %1 to the end of the program's registry entry and parse the folder name as a command argument
|

|

Make that "%1" (with the double quotes) so the path is allowed to contain spaces...

Horrible english, wrong forum, lack of information.
You get an F-, for doing nothing right at all.

To display PDF documents in my app I use the Adobe Active X component like this:
this.axAcroPDF1.LoadFile(@Filename);
this.axAcroPDF1.Show();
This works great for independent forms, but on a MDI form the component stays blank
After a lot of googling I found this in a VB forum:
================================================================
Your child form cannot directly refrence the Acro object like that.
instead of just using this.
AxAcroPDF1.LoadFile("C:\1.pdf")
you need to do it like this.
Form_ParentFormNameHere.AxAcroPDF1.LoadFile("C:\1.pdf")
=================================================================
I've tried to translate this to C# but have to confess I have no clue how to, and also one of the other messages said this solution doesn't work anyhow.
Anybody knows how to do this ?
Thanks in advance
