Hello,
Which is the accepted practice in .NET coding, to just throw everything in a single project into a single namespace, or to separate different parts of a project into different sub-namespaces?
For instance, should I put all structures into a namespace called "Project.Structures", and then put all dialogs into "Project.Dialogs", and so forth?
Thanks,
Rich

If it is a small throw away application then that would be acceptable.

Yes. And split the solution into multiple projects.

Typically I'd say a layering patter would be better (you can, of couse, split the layers in to finer grains if you want). I'd have a UI project, a business project, and a data access project. The reason for that is that it prevents circular references. Your UI project referenced the business project, and the business project references the data access project. If any other references between these projects needst to be set up then I know I'm doing something wrong.

Hi,
I create an user control, and use the following code to create it, is the code ok?
private void func(){
myctl mc=new myctl();
Panel1.Controls.add(mc); //panel1 is a panel I put in a form
mc.show();
}
it works fine, but I think mc should out of range(be destroyed automatically) once the function call end.
Or the controlcollection of the Panel control still keep it alive???
I am listening .....

It will be kept alive until there are no more references to it. Since it is referenced by panel1's Controls collection, it will be kept alive at least until it is either removed from that panel or the panel is disposed and no longer referenced.

Hi,
I hope it's just a simple question. When I unintall my .NET/C# program that I installed using my own setup programe, the program shortcut in the start menu doesn't get cleaned up completely. The content is removed but the folder remains. How can I remove the folder at uninstallation time? Thanks for help!

Why would you be using your own setup program

I am trying to connect to my SQLServer, and i get the message that login faild to my user:
Login failed for user 'YOS-GB5VYJ57W5W\ASPNET'.
why is that?
do i need to change the user?How?
the string that i use is:
mycon = new SqlConnection("Data Source=localhost;Database=RTQ;Integrated Security=SSPI");
Thank you

are you using this code in a webservice? If so, you'll have to add the aspnet user with nt authentication to your sql server logins, then as a user for the RTQ db. Otherwise you'll have to use trusted_connection = no and supply a userid and pwd in your connection string.

I am not using webservice, i am using webaplication.
where can i give the permissions to log in to RTQ?
with the SQLServer Enterprize??
Thanks

In your sQL server Enterprise manager, click on the node for your server, right-click logins, select 'add new login' add that name you got the error on (domainorcomputername/aspnet) select NT authentication, then I think it's on another tab, select the rtq db for that user.

The problem is that you are using Windows Authenitication to connect to SQL Server in a ASPNET Application, you can do one of three things:
1. Remove this from the conection string "Integrated Security=SSPI" and change it for:
"user=my user;pwd=mypassord"
2. Add this in the web.config
<idenity username="DOMAIN\myUser" password="Type UserPasswer">
3. Go the SQL Server and add the ASPNET user as windows user login, that can read and write on that databases you need.

how about this one.. this one might be difficult....
Private Function Decrypt_Key(ByVal bProductKey() As Byte) As String
Dim ilByte As Long
Dim ilKeyByte As Long
Dim nCur As Integer
Dim RetKey As New System.Text.StringBuilder
Dim bKeyChars() As Char = {"B", "C", "D", "F", "G", "H", "J", "K", "M", "P", "Q", "R", "T", "V", "W", "X", "Y", "2", "3", "4", "6", "7", "8", "9"}
For ilByte = 24 To 0 Step -1
nCur = 0
For ilKeyByte = 14 To 0 Step -1
nCur = nCur * 256 Xor bProductKey(ilKeyByte)
bProductKey(ilKeyByte) = Int(nCur / 24)
nCur = nCur Mod 24
Next ilKeyByte
RetKey.Insert(0, bKeyChars(nCur))
If ilByte Mod 5 = 0 AndAlso ilByte <> 0 Then RetKey.Insert(0, "-")
Next ilByte
Return RetKey.ToString
End Function
thank you!!

I really don't think us writing the code for you is going to help much. We've already helped you with a few conversion, but you're really gonna need to learn how to convert yourself, or use tools that will do the conversion for you. I've already pointed you to Reflector; why not just compile that VB.NET code as a dll (if it's not already), point Reflector at it, and have it generate for you C# code?
Here's a screenshot[^] of Reflector generating C# code from one of my .dll files. As you can see, Reflector generated the C# code for me, even though the dll was written in VB.NET.

i had it converted on c# on my own without using convertion tools... but i have a problem with this statement when converting it to c#...
vb code ---> bProductKey(ilKeyByte) = Int(nCur / 24)
i tried it on c# code with this code --> bProductKey[ilKeyByte] = (byte)((int)(nCur / 24));
it compiled correctly but it has a different output already......

Ok, I put your VB.NET code into a VB.NET application, compiled it, pointed Reflector to it, and here's what Reflector had to say:
private string Decrypt_Key(byte[] bProductKey)
{
StringBuilder builder1 = new StringBuilder();
char[] chArray1 = new char[] {
'B', 'C', 'D', 'F', 'G', 'H', 'J', 'K', 'M', 'P', 'Q', 'R', 'T', 'V', 'W', 'X',
'Y', '2', '3', '4', '6', '7', '8', '9'
};
long num1 = 0x18;
do
{
int num3 = 0;
long num2 = 14;
do
{
num3 = (num3 * 0x100) ^ bProductKey[(int) num2];
bProductKey[(int) num2] = (byte) Math.Round(Conversion.Int((double) (((double) num3) / 24)));
num3 = num3 % 0x18;
num2 += -1;
}
while (num2 >= 0);
builder1.Insert(0, chArray1[num3]);
if (((((num1 % ((long) 5)) == 0) && (num1 != 0)) ? 1 : 0) != 0)
{
builder1.Insert(0, "-");
}
num1 += -1;
}
while (num1 >= 0);
return builder1.ToString();
}
I'm telling you, try out Reflector, you'll find it to be a very useful tool.

i already installed it! And thank you very much!! very useful!! but i encounter a problem with this line
bProductKey[(int) num2] = (byte) Math.Round(Conversion.Int((double) (((double) num3) / 24)));
it says that Convertion does not exists in the current context so i made it to this line
bProductKey[(int) num2] = (byte)Math.Round(Convert.ToInt64(((double)(((double)num3) / 24))));
now it says
Error 4 The call is ambiguous between the following methods or properties: 'System.Math.Round(double)' and 'System.Math.Round(decimal)' C:\Documents and Settings\Paul Villacorta\My Documents\Visual Studio 2005\Projects\practice\practice\Form1.cs 307 52 practice

Yeah, sometimes reflector doesn't emit perfect code. Maybe try
bProductKey[(int) num2] = (byte) Math.Round(Convert.ToInt32((double) (((double) num3) / 24)));

it still has an error.... im trying to figure it out.. but cant determine it... help..
