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.
