I would suggest you look up encapsulation and/or information hiding to read about this. I'd add a link to wikipedia, but I didn't think the article there was too helpful - Google should suffice though.
Hope this helps,
Chris

I have an application that contains a dataset with a few datatables. I have a few .csv files that I'd like to load into the datatables. Can that be done? If so, how?
Thanks!

Open the .csv file with a StreamReader, read each line, then do a String.Split on the
commas (do this for each line).
Then insert the rows into the database.
Cheers,

Thanks for your quick response! The CSV file is pretty big, it has approximately 15,000 rows of data. Is that the most efficient way?
Thanks!

Its the quickest way that i'm aware of. If your only doing it once or twice, time shouldn't be an issue, it'll be done before you can get a coffee...

Does it have ot be done using code?
Otherwise, assuming you are using Sql, right click on the db, select Tasks > Import data and follow the wizard

Hi, A few weeks back i found a good article here on CP to do with running a new process from within your own form. It was as if the form was redirecting graphical output and input to the process.
Basicly, the form opened, and the process you defined (iexplore.exe or notepad.exe) would open and run from within your form, not in their own.
At the time i bookmarked, but i have had to reformat and lost all my bookmarks.
I spent over an hour thismorning, and just spent another hour looking through all the C# articles for this one.
I was wondering if someone knew what i was talking about and could point me in the right direction?

Yeah its an awesome app, normally i would just code my own using yours as a base but yours has all you could need just to keep things tidy when your running alot instead of the built in Taskbar grouping in XP.
If i come up with any suggestions ill let you know
Ohh its referenced in your app! Now i remember, thats how i found it in the first place!

Hi All,
I am new here
I have the following scenario:
I need to add an image to an existinf imagelist (winforms)
so simple- but so complicated/
The imagelist is defined with image size 16*16, colordepth- 16...
every action on the imagelist- addition, removal- raises a message: the image could not be added to the image list. (Also when trying to remove an image- not ADD! BUG or something in the resx is curropted?))
If I increase the depth to any higher numbver: I could add\ remove- but the picture are not as should- cut at thr rightsize.
So---
Treying to save the images to files- craete a new image list and so on (We do not have the actual files)- but upon saving- the images are curropted- in any format- bmp, gif etc...
Any help will be appriciated! thank you very much.

How can I filter the following dataTable that is the datasource to a datagridview:
dtMenu has the following fields:
MenuID - typeof(int),
DayOfWeekServed - typeof(DateType),
ChefID - typeof(int)
MenuID links to the dtMenuItems table which has the following fields:
ItemName - typeof(string)
IsLowCarb - typeof(bool)
Description - typeof(string)
...etc
I want to configure the dtMenu where the user can filter the menu items based on whether the item is LowCarb or not. (There are other usages but this is the simplest example)
I know I can do a database query but I want to filter the records from the two in-memory dataTables. My problem would be solved if the datagridview would accept an array of datarows.
Thanks to anyone who can preserve my shrinking ego!

DataView dv = new DataView(yourDataTable, "IsLowCarb=1", string.Empty, DataViewRowState.CurrentRows);
Bind your DataGridView to the dv.

I am writing a little timer program to control usage of computers in a computer lab i work in. I have two text boxes. One for the index number of the user and the other for the password. If the user presses tab key, the screen flickers.
this is the code i use for the full screen
private void mainLab_Load(object sender, EventArgs e)
{
this.Size = SystemInformation.PrimaryMonitorSize;
this.Location = new Point(0, 0);
intLLKey = KeyBoardHooker.SetWindowsHookEx(KeyBoardHooker.WH_KEYBOARD_LL, hooker.LowLevelKeyboardProc
, System.Runtime.InteropServices.Marshal.GetHINSTANCE(System.Reflection.Assembly.GetExecutingAssembly().GetModules()[0]).ToInt32(), 0);
//topmost
this.TopMost = true;
//activate
this.Activate();
}
I also have a system hook which i use to disable the windows key and other special keys. I am running the program on the limited account i have created. I used windows steady state to disable task manager. However if the user continuosly presses the ctrl+alt+del the program crashes and exits.
And last but not least i used a windows service to start the program.

Hi,
.Net 2 VS2005
I have a button that triggers a web service... something like...
ServiceMethods.Method1 += new Services.Method1CompletedEventHandler(Method1Completed);
ServiceMethods.Method1Async(<parameters>);
and the callback method gets called fine...
private void Method1Completed(object sender, Services.Method1CompletedEventArgs e)
{
}
The problem is that the first time the button is pressed which calls the web service the call back method is called once, the second time the button is pressed the callback method is called twice consecutavely, and the third time it is called 3 times and so on...
Has anyone seen this behaviour before - i only want the call back method to be called once.
Many thanks,
Chas

You're adding the event handler each time the button is pressed. You only need to attach the event handler once.
Put this line in your initialisation somewhere.
<br />
ServiceMethods.Method1 += new Services.Method1CompletedEventHandler(Method1Completed);<br />
And leave this line in the button click event.
ServiceMethods.Method1Async();
Simon
