Debug vs. Release is not as clear cut in the .NET world as it was in something like C++. You can still debug release stuff.
What I *think* is probably happening is that you've still got a PDB file despite building in release. This is the file that tells the debugger how to map instructions to lines of source code. If you don't distribute that, then they shouldn't be able to step in the debugger. Also, they'd have to have the source code anyway which they won't.
It's by virtue of the fact you have both source and PDB on your machine you can do it, so no, they won't be able to step through it.
As other's have mentioned, it's very straight forward to reverse engineer .NET with something like Reflector. You can obfuscate it, but that's not that effective. Really, if you need to protect some Intellectual Property you'd need to use something other than .NET, or maybe managed/unmanaged C++. But, ultimately, anything can be reverse engineered.

This is all very interesting, thanks. I am perplexed though because I know for a fact that my test app and my dll are in separate solutions in separate folders. I definitely did compile the dll in release config and, while the compiler did create a .pdb file (in the release directory) I only copied the .dll file into my test app's folder.
At any rate, I fiddled around with Dotfuscator a bit and I seem to have gotten to a point where the .dll is ugly enough to at least dissuade the average programmer from decompiling it and at least I can't step into the code in debug mode anymore.

I find that when I reference a DLL that's been built in release mode while debugging, Visual Studio pops up a message saying it can't be debugged and asks if I want to continue. So I haven't seen the situation you describe.
But I also delete the PDB files, so maybe that helps.

Hello,
I want to send some text or keys to other applications say "notepad,calc,etc.". I have tried but i failed. New window is opened but key is not displayed on the window.
Here is my code:
[DllImport("User32.DLL")]
public static extern bool SetForegroundWindow(IntPtr hwnd);
[DllImport("User32.DLL")]
public static extern int SetActiveWindow(IntPtr hwnd);
newprocess.StartInfo.FileName = "calc.exe";
newprocess.StartInfo.UseShellExecute = false;
newprocess.StartInfo.RedirectStandardOutput = true;
newprocess.StartInfo.RedirectStandardInput = true;
newprocess.Start();
SetActiveWindow(newprocess.MainWindowHandle);
keybd_event(0x61, 0x45, KEYEVENTF_EXTENDEDKEY, 0);
keybd_event(0x61, 0x45, KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, 0);
keybd_event(0x6B, 0x45, KEYEVENTF_EXTENDEDKEY, 0);
keybd_event(0x6B, 0x45, KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, 0);
keybd_event(0x61, 0x45, KEYEVENTF_EXTENDEDKEY, 0);
keybd_event(0x61, 0x45, KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, 0);
I have tried with many functions like SetForegroundWindow(), but there is no change. I have tried with notepad and used Sendkeys.Sendwait(), and its working fine. But help me for keybd_event().
Please help me its urgent.
Thank you in advance.

What's keybd_event?
Not entirely sure how easy this is to do these days, as a protected operating system should to some extent stop processes interfering with each other.
What you probably want to do is call SendMessage on the window passing in keyboard messages. Wouldn't like to say whether that will work or not.
Regards,
Rob Philpott.

Thank you for your reply,
Keybd_event() is working fine for opening start menu and search files. But when i open any new application with process class its not working. I think focus is not done in newly created process window and keyboard focus is also not there. But i have setfocus() for keyboard focus and still its not working.
Please help me.
Thank you in advance.

I don't know if anyone on here has used the DDay.iCal library to create iCal files, but I thought I'd throw this out anyway, and see what I get. I've posted the same question just now on their forum as well. Basically, I'm trying to create an iCal file that includes reminders; in other words, when I open the item in Outlook, the appointment has, say, 1 Day as the reminder setting. I just can't seem to get it to work, though. The appointment looks good, except for this one facet. Here's the relevant code:
Alarm alarm = new Alarm();
alarm.Action = AlarmAction.Display;
alarm.Description = "Reminder";
alarm.Trigger = new Trigger(TimeSpan.FromDays(-1));
evt.AddAlarm(alarm);
Any ideas? Thanks in advance. If the DDay forum gets back to me, I'll post their response here for anyone else to view.

Hello all,
I have one problem in my module. in my project we are using the charcaters ASCII 32 to 255. we are display the character based on value i.e., if we want display Ö char just convert the 153 to charcater (char x = (char)153). But one of my coustmer wants if he enter the character by pressing Alt + 153 that will also we have to display. Now we are facing the problem Alt + 153 charcter is giving 214 value.we are not the proper value for that charcter. like this from 128 to 255 character we are facing the problem. can any one suggest some solution? it is very helpfull to me.
thanks in advance

That is realy odd. "Ö" that is the char when i press ALT + 153. "Í" that is the char with ALT+214. Have you tried using Encoding.ASCII?
Also windows have Character map app. Some characters show on it with alt combination.

Thanks For ur reply,
If u try to debug the code.
char ch1 = (char)153;
char ch2 = 'Ö'; // alt + 153;
in this case ch1 value will be 153 and ch2 value will be 214.

Alt Codes[^]
Acording to that page, those codes are not ASCII or unicode. But rather ANSI or old MS-Dos code page based. if the numbers doesn't have zero in front of "Alt+153" uses MS-Dos code pages.
System.Text.Encoding.GetEncoding(850).GetChars(new Byte[]{153})[0]
That code uses code page: 850. That is "Multilingual (Latin-1)" (Western European languages) (Copied from wiki, link below)
List of Code pages[^]

|
|
|

char x1 = (char)153;
char x2 = 'Ö';
byte ss1 = System.Text.Encoding.GetEncoding(850).GetBytes(new char[] { x1 })[0]; // result 63
byte ss1 = System.Text.Encoding.GetEncoding(850).GetBytes(new char[] { x2 })[0]; // result 63
this is not working.
i want the value 153 if i use the character (char)153 and alt+153.

edit:
It isn't:
.GetEncoding(850).GetBytes
It shoud be:
.GetEncoding(850).GetChars
char x1 = (char)153;
char x2 = 'Ö';
char ss1 = System.Text.Encoding.GetEncoding(850).GetChars(new byte[] { Convert.ToByte(x1) })[0];
byte b1 = System.Text.Encoding.GetEncoding(850).GetBytes(new char[] { x2 })[0];
Edit: I have tried your second code, second ss1, it shoud work. Try code-page 437 instead 850.

Are you askinng the folowing: User Press ALT+153 and you want same character with a character code: 153?

yes i am asking that one if user enter the charcter by using Alt+153 or (char)153 convertion also i want the same value 153.
i think it is little bit confusion. in my module i have symbol editor it contains the character from 32 to 255. if user want the value on the symbol editor he just double click on the value(if user wants "Ö" user will double click on the charcter. in this case i am getting the position of the character in that editor. the position is 153) user can use this symbol editor or he can use directly by pressing the Alt+ value.
in my code i am just coverting the charcter what i am having in the symbol editor text box. this is the actual problem i am facing.
thanks in advance

That is gonna be hard but i think I found info:
Encoding unicode = Encoding.Unicode;
Encoding CodePage850 = Encoding.GetEncoding(850);
char c1 = (char)'Ö';
byte[] ub1 = Encoding.Unicode.GetBytes(new char[] {c1});
byte[] ub2 = Encoding.Convert(unicode, CodePage850, ub1);
More info here[^][^]
|
|
|
|
|
still that example is giving 214 only. but i want 153 at any case.
|
|
|
|
|
Thats of. Did you tried updating .net framework or using diffrent version?
My Picture[^]
Do you have same output as i have from my picture? (Look at local Watch)
|
|
|
|
|
Encoding unicode = Encoding.Unicode;
Encoding CodePage850 = Encoding.GetEncoding(850);
// Test character
char c1 = (char)153;
// Convert 153 from Char to array.
byte[] ub1 = Encoding.Unicode.GetBytes(new char[] {c1});
// convert char code 214 from unicode to CodePage850, with a char code 153.
byte[] ub2 = Encoding.Convert(unicode, CodePage850, ub1);
If use char c1 = (char)153;
this case ub2[0] is 63. that is the problem i am facing.

It seems on my Side it behaves differently than on your side. I am using Visual Studio 2008. My default project uses .NET framework 3.5. I have both Visual Studio 2008 and .Net Framework 3.5 upgraded to SP1.
What version of Visual Studio or other IDE you are using? Witch .NET framework are you using and is it upgraded (dotNET 3.5 SP1 or dotNET 2.0 SP2)?
If you have fully upgraded .NET Framework, I Suggest your project to use different version of .NET framework

impossible. ASCII is a 7-bit code, it goes up to 127.
You probably mean ANSI characters, those are 8-bit; chose the right code page, in Western Europe it probably is 1252.

ya that is ansi only. i have tried with 1252 code page also but i didn't get the result what i am expecting.

I have a 2d function that can be represented in a grayscale Format32bppArgb bitmap. I simply divide each value of the function by the maximum value in the function then multiply by 255. I use a lockbits routine to set the pixels.
I have a reversible transformation (similar to an FFT) that I apply to the function and I can represent it the same way.
I wanted to store the transform in the bitmap. The trouble is, if I use an 8 bit color depth, it only has 256 discrete levels. This is too coarse for my application (I cannot inverse transform the data stored in the bitmap and obtain the original function). A 16 bit color depth would give me 65536 discrete levels and this would do nicely.
The trouble is, I have not found a way to render a 16 bit color depth bitmap. I seems that the required Format16bppGrayScale and format and the Format64bppArgb are not functional VS. (I use VS 2005). Most of what I have seen for a work around involves scaling the bitmap data to an 8 bit color depth format.
I would like to be able to both store and “see” the transformed function in 16 bit detail. (Having the visualization be based on a bitmap structure isn’t a necessary requirement for me.) I have looked at some alternate approaches (such as directx) for managing this task but I haven’t been able to noodle out exactly how to do it. The Google stuff I’ve found is pretty sketchy on the implementation steps for my limited skills.
Can anyone give me a boost?
