hi
using my program i need to read/write few files (like Ms access database,txt files ,Autocad drawing file,image files) from the server which is restricted to user.
user has no permission to read and write those files from server
i used Code Acess Security thru .Net Configuration Tool for accessing those files. it solved the problem
but when i made a setup of the Application and installed in client system
its giving error. "Access denied"
does the .net Configuration Tool which i set few permissions should present in client system also.
how can i do it
user has no permission but my application installed at user should have permissions to read and write those files.

It is Good to have security , but this type of Security will always cause problem for your users.Tell the Admnistrator give give them permissions to the Files.

hi
i developed a software using c#
now i need to apply security for it.
what i mean is no one can decode my exe and other dlls.
and develop the similar software.
one more doubt is ...
i made a setup using dotnet
then after installing it , exe file and other dlls are installed at a location.
can any one break my exe and get the actual code what i written

Yes.
The best you can hope for is to obfuscate your software before release - Google is a big help here.

Then the computer can not decode it either so it wouldn't run, is that really what you want?vijaylumar wrote: can any one break my exe and get the actual code what i written
Sure, they just don't get the comments and local variable names back.
So, apply cheap/free obfuscation - no level of obfuscation (not even that Salamander thing) will stop an average hacker (so it's just a waste of money really), but simple obfuscation will stop some of the 16 year old kiddo's from messing around with your code too much.
Might I recommend Phoenix Protector[^]? It's free and pretty good.

I agree, Pheonix Protector would be your best (free) tool.

hey dude what is obfuscation??
|
|
|
|
|
That's when the code in the exe/dll is made as WTF-ish as possible on purpose to make reverse engineering harder
|
|
|
|
|
For this you need to obfuscate your code DLLs. Try to get some good obfuscation software for you.

Hi,
setting Form.TopLevel false opens up a whole lot of possibilities.

Hi all I am facing a problem in my application some times it appears to user that system/ application get hanged and he is unable to do ANY THING, the only option left to him that to kill the application using Task Manager. I found the reason that actually my message box is went to back of the current window due to which focus gets lost from the front.
I searched on the net and found that in my application overriding of a windows method cause such problem
this method is used to draw and display a timer/click on the MDI form rest i dont know about the functionality.
I am attaching the code if any body can help please reply as it's really confusing for me and i am not getting any solution for the same
protected override void WndProc(ref System.Windows.Forms.Message m)
{
try
{
base.WndProc(ref m);
switch (m.Msg)
{
case (int)WM_TIMER:
if (PreferencesController.IsAutoLockStart)
{
if (PreferencesController.IsSetAutoLock)
{
actHook.Start();
PreferencesController.EndTimeAutoLock = DateTime.Now.AddMinutes(PreferencesController.LockWorkStationTimeInMinute);
PreferencesController.IsSetAutoLock = false;
}
AutoLockWS();
}
if (PreferencesController.IsShowDateTime)
Main_OnNcPaint(ref m);
if (DateTime.Now.ToLocalTime().ToShortTimeString().Equals(
ConfigurationService.GetExcelMacroExecutionTime()))
ExcelFile.RunMacro();
break;
case (int)WM_NCPAINT:
if (PreferencesController.IsShowDateTime)
Main_OnNcPaint(ref m);
break;
}
}
catch (Exception ex)
{
ex.Message.ToString();
}
method called in above code is
private void Main_OnNcPaint(ref Message m)
{
paintTitleBar = m;
IntPtr hdc = GetWindowDC(m.HWnd);
Graphics g = Graphics.FromHdc(hdc);
RectangleF titleBarRectF = g.VisibleClipBounds;
int formWidth = (int)titleBarRectF.Width;
int CaptionHeight = Bounds.Height - ClientRectangle.Height;
Size CloseButtonSize = SystemInformation.CaptionButtonSize;
int X = formWidth - (CloseButtonSize.Width * 4) - 200;
int Y = 4;
int width = 200;
int height = CaptionHeight - 10;
string dateText;
if (PreferencesController.IsShowDateTimeWithSeconds)
{
dateText = DateTime.Now.ToString("dd MMM yyyy hh:mm:ss tt");
}
else
{
dateText = DateTime.Now.ToString("dd MMM yyyy hh:mm tt");
}
RectangleF timeDisplayRectF = new RectangleF(X, Y, width, height);
g.FillRectangle(new SolidBrush(Color.DarkBlue), timeDisplayRectF);
Font font = new Font(Font.FontFamily, Font.Size + 2, FontStyle.Bold);
g.DrawString(dateText, font, new SolidBrush(Color.White), timeDisplayRectF);
g.Dispose();
ReleaseDC(m.HWnd, hdc);
m.Result = IntPtr.Zero;
}

please edit your message and put all code inside PRE tags, no one is going to read it as it is now.

Hi,
that code is mysterious to me. I do have two suggestions:
1.
add a font.Dispose() to clean up the font you created. Gives better memory handling.
2.
if you don't do it already, modify MessageBox.Show(someString,...) to MessageBox.Show(this, someString,...) that might solve the problem.

I am storing card displays (eg J♣) in a list box through a list <KeyValuePair<string, int> and I want to order the cards numerically from greatest value to smallest value in the list box. When I change the sorting property on the properties box to "descending", the list is sorted inverse-alphabetically (ie Q is at top and 10 is at the bottom). I want to sort the list descending numerically, by value, so that A is at the top and 2 is at the bottom. How can I do this?

Here is one way MSDN - ListBox.Sort Method[^].
Alternatively you can put your string and int into a class and implement the IComparable interface. Then, possibly, put them into a collection to add via the ListBox.DataSource property

You can implement a custom type for Cards and override the CompareTo() method to implement custom sorting. Something like:
internal enum CardSuits
{
Spades = 0,
Hearts,
Diamonds,
Clubs
}
internal enum CardValues
{
Two = 0,
Three,
Four,
Five,
Six,
Seven,
Eight,
Nine,
Ten,
Jack,
Queen,
King,
Ace
}
internal class Card : IComparable
{
internal CardSuits Suit;
internal CardValues Value;
internal Card(CardSuits Suit, CardValues Value)
{
this.Suit = Suit;
this.Value = Value;
}
public int CompareTo(object obj)
{
int MyValue = (int)Value;
Card OtherCard = (Card)obj;
int OtherValue = (int)OtherCard.Value;
return MyValue.CompareTo(OtherValue);
}
public override string ToString()
{
StringBuilder sb = new StringBuilder();
switch (Value)
{
case CardValues.Two:
sb.Append("Two");
break;
case CardValues.Three:
sb.Append("Three");
break;
case CardValues.Four:
sb.Append("Four");
break;
case CardValues.Five:
sb.Append("Five");
break;
case CardValues.Six:
sb.Append("Six");
break;
case CardValues.Seven:
sb.Append("Seven");
break;
case CardValues.Eight:
sb.Append("Eight");
break;
case CardValues.Nine:
sb.Append("Nine");
break;
case CardValues.Ten:
sb.Append("Ten");
break;
case CardValues.Jack:
sb.Append("Jack");
break;
case CardValues.Queen:
sb.Append("Queen");
break;
case CardValues.King:
sb.Append("King");
break;
case CardValues.Ace:
sb.Append("Ace");
break;
default:
sb.Append("???");
break;
}
sb.Append(" of ");
switch (Suit)
{
case CardSuits.Spades:
sb.Append("Spades");
break;
case CardSuits.Hearts:
sb.Append("Hearts");
break;
case CardSuits.Diamonds:
sb.Append("Diamonds");
break;
case CardSuits.Clubs:
sb.Append("Clubs");
break;
default:
sb.Append("???");
break;
}
return sb.ToString();
}
}
...
List<Card>CardList = new List<Card>();
CardList.Add(new Card(CardSuits.Hearts, CardValues.Three));
CardList.Add(new Card(CardSuits.Clubs, CardValues.Queen));
CardList.Add(new Card(CardSuits.Diamonds, CardValues.Nine));
CardList.Add(new Card(CardSuits.Spades, CardValues.Ace));
CardList.Sort();
listBox1.DataSource = CardList;
2+2=5 for very large amounts of 2
(always loved that one hehe!)

Hi,
if your ListBox (or any other collection) contains items of type T, then you could provide an object implementing IComparer<T> and pass that to the Sort method.
All that interface takes is providing a simple method int Compare(T x, T y) in which you can implement any sorting order you like.
------------------------------------------------------------------------------
FWIW: you can edit and delete your own messages if you need to.
[EDIT]
Sorry, the above is insufficient, ListBox.Sort() does not take any parameters.
There are basically two ways of doing it:
1.
implement your own sort method; e.g. a bubble sort where you compare two items (in any way you see fit) and swap them if necessary.
2. better way:
use an intermediate collection, e.g. an array. This means:
- ListBox.Items.CopyTo(array,0) copies the items into an array
- ListBox.Items.Clear() removes the items
- Array.Sort(array, IComparer) sorts the items
- ListBox.Items.AddRange(array) adds them again, in the right order.
