hey guys, im programatically sharing a directory, but i noticed that the permissions were screwed. so tried using
<br />
FileSecurity fs = File.GetAccessControl(FolderPath.TrimEnd('\\'), AccessControlSections.All);<br />
fs.AddAccessRule(new FileSystemAccessRule("Everyone", FileSystemRights.ReadAndExecute, AccessControlType.Allow));<br />
File.SetAccessControl(FolderPath.ToString().TrimEnd('\\'), fs);<br />
but it creates the permission for that folder only, but when actually viweing the permissions from explorer, there is a field that states: "Apply to", and it says "This folder only." is there any way of changing that to include this folder and all subdirectories?

Hello,
VS 2008
Adding number and letters on buttons.
I have a form that looks like a phone with buttons. I am wondering how to put number and letters on the buttons.
i.e.
1
abc
2
def
3
ghi
Just another question. I have wired up all the buttons for one click event. And display the numbers in the text box display.
Code:
private void DialerKeyPress_Click(object sender, EventArgs e)
{
this.txtDisplay.Text += ((Button)sender).Text;
}
How would it be possible to display something like a 'c' or 'e' etc. The user would have to click 4 times for a 'c', and twice for a 'e'.
How is this normally implemented in a normal phone application.
Many thanks for any advice,
Steve

Can you provide a link to one of these "normal phone applications" because off the top of my head I just can't think of one?

Use Text property of the Button class. To specify new line character during runtime use Environment.Newline If you are setting text during design time, you can do it easily by designer.

In the click button check if the previous button pressed is the same as currently pressed button. If yes then just replace last character of txtDisplay.Text with the character which comes next on the button. You will need a counter for that. You will also need to check how much time passed from previous click

You could use images on the buttons - a bit like they have in the "skinned" Smartphone emulator in Visual Studio.

Here I'd be inclined to use a timer - if the user clicks the button before the timer has expired cycle to the next available character, if the timer has expired accept the input.

Hi all,
i'm facing with an interesting application error.
in my app I used a serial port to read some bytes from an external electronical card and succeded on it. Then a added a web cam video capturing fearture to my app for some better user experience.... I coded the web cam via callling avicap32.dll and used it's defined functions etc... And as you know serial communication is quite easy, no need to explain it i think...
Now to the problem is when run the app , it works at first time, but at second time i cannot see the form design at runtime....and i try to close it, the debuging stops but when i look at task manager the exe still runs under system protection, i cannot close it, or generate a dump file of it etc....
Does anyone have any idea, i never faced an error somethink like this, and don't know what to do next???
Thanks for all replies

Hi,
the most common way to get an app to refuse an exit (e.g.when you close the main form)
is by having foreground threads that are not done yet. If you have threads that should
not prevent Application.Exit() or MainForm.Close() to succeed, you should set their
IsBackground property true (default is false).

try to use a richtextbox as cell renderer

I have written a generic (i.e., having a type parameter) undo-redo component that I would like to add to the toolbox. The problem is, how can I drag this component to the component tray, and specify the type (of objects on the undo stack). I can't just make the component use system.object, since the objects must be ICloneable (and that would not be "generic" anyway).
When the component is dragged onto the component tray, an instance of the component is created, so it needs to know its type. Perhaps, the initial type could be system.object (how would you specify this for the drag?), and then the actual type could be be given as a property of the component, and changed when the property is changed? (How would you do this?)
Interesting/challenging problem, huh? (...well, perhaps not for the gurus).
Does anyone have an elegant solution?
Thanks,
Tom

I think I follow you and, if I do, you need a Designer object that wraps your Generic. So the designer object doesn't need a type parameter to create an instance in the designer. The designer object will generate the code for the generic based on the type as a property the user will set. I imagine you would default this to "object".

Hallo
I'm new to C#. I used to make databases with Microsoft Access, now I want to do it with c#.
I used a lot of Comboboxes with multiple columns (such as : number, name, adress of a person).
How can I do this in c#?
Thank you for your help

guidoursus,
You want to use C# as a database backend?, why would you want to do that? I dont think i am understanding your question.
Regards,
Gareth.

The data I need are on an a server in different databases. I have to make several forms, some to see the data of the persons, some other to ad new data about these persons.

Hi all,
I want to run a console application in C# from visual studio in debug mode (by pressing F5).
Is there a way to enter the arguments thru VS?
Thank you.

I think you can set commandline arguments in Project settings
fafafa, ringakta icke sådant som bringa ack så naggande högönsklig välmåga å baronens ära.

There sure is. Take a look at your project's properties under the debug tab (or wherever it is on the version of Visual Studio your using). You'll find a field called Command Line Arguments.

Hi All, I am in the process of re-writing a business application that was originally developed in VB6.
I have decided to seperate the application into tiers and have a Data Access layer, Business Logic layer and business entities. I've writtern some generic classes which are inherited by my business logic and business entities to provide certain basic functionality.
Ultimately my question is regarding unique identifiers for my business entities. If for instance i have a Fleet object which contains vehicle entities and that the vehicle entities have a VehicleID field. This field is used to uniquely identify it in the database. I didn't want to make it a public property because that would allow the user to edit it and upon calling update on the entity, would overrite an incorrect record in the database. I then thought about possibly using the constructor so that when the entities are originally pulled from the database and the instances of the entities are created, the ID field is passed as a parameter and only a property getter exists to read the ID value if required. This also poses problems because if i was to create a new entity i.e Vehicle v = new Vehicle(10) this could pose a problem because a vehicle with an ID of 10 could already exist and could potentially be overwritten in the db.
Since i am the only developer i suppose i could use either of the two methods and just make sure i don't make a silly mistake but i would like to know if it is possible to provide the sort of functionality that offers protection from such mistakes.
Thanks in advance.

Yeah, typically in these situations you let the database assign the ids of objects, perhaps by using identity columns. Your objects would only be assigned an Id after persisting them to the database. Existing objects are loaded by id, new objects can be created adhoc, but only become 'permanent' with an id after a save to the database.
Nice to see that your thinking this stuff through, you wouldn't believe some of the dire hacked approaches I've seen 'in the field'.
Regards,
Rob Philpott.

Thanks for the reply. I'm pretty new to C# and would like to 'Do It right'. But i'm still unclear of a good approach.
How else could i get the ID field into the entity without exposing the entity to potential abuse/mistakes. If i use the constructer of the entity when i populate it from the database, that constructor would still be available throughout the program and would allow an instance to be created adhoc along with a potentially invalid ID. I thought about creating a hidden property by setting it's browsable and editor browsable attributes to false but this felt like a hack to me.
