hello friends!!
I have made a library for my c# project by combining 3 libraries (using ilmerge).
I wanted to know, is it possible for someone to decompile my new library or view the code?
if yes, how do i protect it?
or is there any other way of merging the library with my project?

Use Reflector[^] to see the result.
Normally a dll can be protected by Obfuscation.Dotfuscator is a Visual Studio Tool using for obfuscation.
|
|

dotfuscator is good but it does not encrypt the code.
also the project shows an error after being linked with the obfuscated library. obviously because it cannot import the namespaces. how do i correct this? do i need to merge my dll with exe?
|

I think you are using dotfuscator in the Visual studio project Dlls.Instead of that use it for dll's and exe in the BIN folder.ie,in the output directory not in the Visual Studio project.
While using dotfuscator browse all of your dlls and also your exe from your build output directory.Otherwise this dll won't work with that exe because of the change in method names and private variable names.

Thanks arun,
I was only importing dll and not the exe
Now i get the problem.
Thanks again.

Wow, awesome tool! Thanks!
I wish there was something like that for my VB6 code that I also have to maintain. Of course, there's no time, money, etc to convert my VB6 code to .NET. :-|

Wow, thanks!
My desire is for something that will help me find the dependences and code in my VB6 program. By doing a google on VB6 disassembler, I found a bunch of stuff.
I always thought that VB6 compiled directly to assembler/machine code.
My VB6 program started out as a simple quick interface to some custom hardware. However, over the years, it's become a huge monstrosity. Since the program was never planned to be huge with many diverse support functions, it's become a bunch of added_on/hacked_on functions.
I've started the new version in C#. And, I'm and doing the code and functions properly this time to support a complex GUI. However, for a few reasons, I'll still need to support the VB6 program for a few more years. I dread every time I have to go back to VB6 and Visual Studio6. However, as long as I'm getting paid, then it's all good.
Wow, also, I just realized. I have a proprietary calibration routine in my VB6 code. It's part of the overall code base. Now, I just disable/hide that Windows form in the version of code that goes to our customers. However, it seems a VB6 decompiler can expose that routine. Yikes! That's good to know. From now on, I'll strip out that module when I build a customer code version.
By the way, I knew to strip out that proprietary calibration module in my C# customer code version. Until I find/see a very good way to protect that C# code, I'll keep doing that. It would be nice to have just one single C# code base.
Thanks again!

Hello. I'm having a problem with the codes i used for sorting strings using radix sort..I always get the IndexOutOfRange exception.
Here is the code:
int N = arrayOfLastNames.Length;
for (int a = 0; a < arrayOfLastNames.Length; a++)
{
int W = arrayOfLastNames[a].Length;
Console.WriteLine("{0}", W);
string[] temp = new string[arrayOfLastNames.Length];
for (int d = W - 1; d >= 0; d--)
{
int[] count = new int[50];
for (int i = 0; i < N; i++)
{
count[arrayOfLastNames[i][d] + 1]++;
}
for (int k = 1; k < 256; k++)
{
count[k] += count[k - 1];
}
for (int i = 0; i < N; i++)
{
temp[count[arrayOfLastNames[i][d]]++] = arrayOfLastNames[i];
}
for (int i = 0; i < N; i++)
{
arrayOfLastNames[i] = temp[i];
Console.WriteLine("{0}", arrayOfLastNames[i]);
}
}
}
How will i prevent that from happening?
Can someone please help me? I really need to finish this before saturday because it's the passing date. I have exams tomorrow until this coming monday. If I solve this problem today I'll be able to finish it until tomorrow because i'll be doing one more procedure tomorrow and that's the binary search. So please help me.

Looking at the part that fails a bit closer..
int W = arrayOfLastNames[a].Length;
Console.WriteLine("{0}", W);
string[] temp = new string[arrayOfLastNames.Length];
for (int d = W - 1; d >= 0; d--)
{
int[] count = new int[50];
for (int i = 0; i < N; i++)
{
count[arrayOfLastNames[i][d] + 1]++;
W gets the length of the first item in arrayOfLastNames. In your for-loop you declare
for (int d = W - 1; d >= 0; d--)
An array in C# is zero based so the characters in the first name (of the last names) will be indexed from 0 to W - 1 which equals d, right? And you declare this in your for-loop but then you add + 1 again in the count[arrayOfLastNames[i][d] + 1] part causing the exception. You can't add 1 when d is the end of the array

Actually I'm not the one who created the code. I just got it from the net so I just copied and pasted the things that would fit in the code...
|
|
|
|

Maybe you should take some time to go through code you 'just copy and paste', making sure you understand it...

in my C# application.
for example i have opened a IE application and Word Application if i change from IE to Word i should get an event.
How can i do it...

When it comes to the IO part, use the FileSystemWatcher class.

Thanks for the reply.
it is not related with IO part.
My need is this when ever i change my IE Application(tab,minimize) the next focused application may be(word, excel, notepad ...) has to be killed.so i need to get the event first of all

thanks

At runtime I need to modify the content of a ToolStripMenuItem.
I've made the changes (added and/or removed new items) but cannot figure out how to refresh or notify the MenuStrip to display the changes.
The menu changes are designed to persist between invocations of the program - and they show up properly when the program is closed and then re-executed. So, I know I've defined and added all of the items correctly - just can't get the changes to appear immediately after they're added.
Any ideas would be appreciated.

Did you try to manually update status bar through code? I am not sure about exact solution but in your case I think it should work.
|
|
|
|
|
Not sure what you mean by "update". Is there a method somewhere that performs an update of the MenuStrip or its items?
|
|
|
|

I'm tryed add, it's work! so, your App should work too, or you override sth.?

User Error!
Found the problem: was referencing the wrong instance of the form that contained he menustrip. When using the "real" form, everything works as it should.
Thanks for your help.

Hi,
My situation is this, I have 3 comboboxes (drop down list only, not editable), and If the user changes the value of one of the, the other two should change too.
I have used the SelectedIndexChanged Event successfully to update the other two comboboxes. But I have 2 issues with it, first: The code is not pretty, I have to repeat the same 3 times and secondly everytime a call is made to one combobox's SelectedIndexChanged event the other are called too because I update the indexes of those too in the first call. I know it's kind of hard to understand like this, so here's what I'm doing:
private void SubNetCountCombo_SelectedIndexChanged(System.Object sender, System.EventArgs e)
{
HostCountCombo.SelectedIndex = SubNetCountCombo.SelectedIndex;
newsubnetmaskcombo.SelectedIndex = SubNetCountCombo.SelectedIndex;
}
private void HostCountCombo_SelectedIndexChanged(object sender, System.EventArgs e)
{
SubNetCountCombo.SelectedIndex = HostCountCombo.SelectedIndex;
newsubnetmaskcombo.SelectedIndex = HostCountCombo.SelectedIndex;
}
private void newsubnetmaskcombo_SelectedIndexChanged(System.Object sender, System.EventArgs e)
{
SubNetCountCombo.SelectedIndex = newsubnetmaskcombo.SelectedIndex;
HostCountCombo.SelectedIndex = newsubnetmaskcombo.SelectedIndex;
}
I thought of using a bool variable as a switch, so that everytime I enter each of those events it turns true and when it goes to the other methods I use an if to check for that variable, if it's true I just get out. But it's still not pretty... So.. I'm not sure if there's a better way of accomplishing this..
Thanks!

If any selection will change the other two,. you'll get into an infinite loop, unless you set some sort of flag which will tell the event handler not to do anything. You can also put all of these into one event handler, and just have it check which control it is working with, and then set the other two.

mmm.. As I said, any selection changes the other two, But no, I do not get into an infinite loop, It only repeats two times the events and then gets out, but you don't notice it. It's not like it slows down the program or anything.
And about the flag, that's what I said in the end of my comment, I used it, but I just don't like the way it works. I want to know if there's another way to accomplish this, without:
1. Having to use a flag.
2. Having to "repeat the instructions" as I'm doing in the excerpt I pasted here.
Thanks
