Running .NET applications on computers without the framework

Is this possible? I have to make a project for school and I chose to do it in C#. Is there any way that I can run a .NET application on a computer without the installed framework? (copy the class files + other files on a CD or something)

Thanks

The standard is answer is No. You have to install the same version of the .NET Framework that you developed your app against.

There are exceptions to this, but those tools cost a bundle of $$$.

Probably installing the framework...

It can be downloaded freely from the microsoft site.

the .net framework installer has about 20 megs.. maximum.. i don't think this can be a problem for anyone to download and export to a removable media.

Well, a simple search for ".NET native compiler" reveals, Salamander[^]. It's $500US minimum. Are you really willing to spend that kind of cash on a class project?

Yes, the or something is to put the framework on the CD as well. This is a silly question - if there was an easy way to not use the framework, why wouldn't everyone just do that ?

use mono to compile it to native code. or embed mono. instead of .NET Framework. I may work.

Monitoring Exceptions from the core

22-Oct-05 1:18

hey all,

Is there a tool to monitor handled exceptions of the core of .NET framework which slowes down my application? I need something like this to determine what kind of exceptions are raised when i use a datagrid. While using perfmon i can there are thrown exceptions but not where and why.

Please Help!

Thanks, Bernd

Hello people,
I was speaking with a friend of mine about which are the most performance-decreasing exceptions that may occurr during the execution of a program.
The application we were talking about is an enterprise one,(for which we're involved all day long in coding) and it has classical structure from PL to DO.
We have taking the conclusion that the System.Xml.Schema.XmlSchemaException class and the Parse one are the ones that teorically can affict our application most.
How can we check the entire production to trace the exception's count?
What are the most common exception that you've found?
Thanks a lot

You can use Perfmon (type perfmon.msc at the command prompt) and the .NET CLR Exceptions Performance object to track the number of exceptions thrown.

character exchange brings wrong result

Hi
I found a very strange result after trying to exchange some characters:

Public Shared Function change_char(ByVal s As String, ByVal from_char As String, ByVal to_char As String) As String
While s.IndexOf(from_char) > -1
s = Mid(s, 1, s.IndexOf(from_char)) + to_char + Mid(s, s.IndexOf(from_char) + 2, s.Length)
End While
Return s
End Function

If I call this function with german character ÄÖÜ.., everything is OK,

mytext="ÄÖÜßäöüß"
Dim s As String
s = change_char(mytext, "ä", "ae")
s = change_char(s, "Ö", "oe")
s = change_char(s, "ü", "ue")
s = change_char(s, "Ä", "Ae")
s = change_char(s, "Ö", "Oe")
s = change_char(s, "Ü", "Ue")

but

s = change_char(s, "ß", "ss")

goes wrong and bring unlimited ss, because it finds even after the change to ss the character ß.

Does anybody have an explanation for that?

Thanks in advance

Hard to say, but I am quite sure String.Replace doesn't have the problem - so why not use it?

Hi,

changed it to

While s.indexof("ß") > -1
s = s.Replace("ß", "ss")
End While

and the problem is still there.

"äß uuuu" becomes "ässssssssssss... uuuu"
This only happens with the ß-character, every other character seems ok.

You should NOT use a while loop. Replace will replace all places the ß character is used.

Apparently there is some culture aware comparison between ß and "ss". I do not think you will have any problems with it if you do not loop the replace, but worst case you can always change the thread culture to "en-US" in the function - just remember to use a try/finally (probably called something else in VB, I only program C#) block to ensure the culture is changed back even if an exception is thrown in the code.

I try to understand the difference between IL and machine code executable so that I can see the relationship between IL and CLR. Suppose that I compiled aPgm.cs
csc.exe /debug+ aPgm.cs
This creates stand alone executable. I can see it using ildasm.exe. Is this exe file machine code? Then which is machine independent code or IL D'Oh! | :doh:

?

Thank you in advance

The exe file has MSIL and not machine code. That's what makes the exe machine independent. At runtime, the JIT compiler generates machine code on the fly. If you really want to see how IL gets compiled to machine code, download this[^], load the SOS (Son of Strike) extension, let the method you want to execute run once and then give the !u command, which unassembles the JIT code.

Dear Sentil,

Let me ask one more question before downloding. How about other exe files one can produce using any compiler other than .NET. like VC++? I can see their metadata using ILDASM. Then what is the difference those exe file, one created from .NET and the other is created other than .NET

There is no ".NET" compiler, there are C# compilers, MC++ compilers, VB compilers and so forth. For VC++, the same compiler can generate IL or machine code based on a command line switch (/clr). So all the above compilers generate IL, so there is no difference. That's why .NET supports language interoperability i.e you can use VB dlls in C#.

So yeah, there's no difference between code generated by different language compilers, providing they're targeting managed code.

Strong Named Assemblies

kapildhir 19-Oct-05 19:38

19-Oct-05 19:38

I have created a new keypair: "C:\SOURCE CODE\keypair.snk" and specified it in my AssemblyInfo.cs as [assembly: AssemblyKeyFile(@"C:\SOURCE CODE\keypair.snk")]

When I examine my keypair using "sn.exe -t C:\SOURCE CODE\keypair.snk" it gives me a public key token which is different to that which is returned when examining the output of my app: "sn.exe -T C:\SOURCE CODE\MyApp\bin\MyApp.dll" ???

Am I missing something or Is this right? If so, which Public Key Token should I refer to in my web.config - the keypair.snk or the MyApp.dll one?

Pls help
Thanks in Advance

Running sn -t on the snk file failed with an error message for me, I wonder how it worked for you? Anyways, AFAIK, you should give the dll file to know the public key token.

The command works fine for me.The output is as follows:-

Public key token is cfc0b9a3c52b17fb

As you can see the public key token extracted from both are diffenent.
If you could tell me the rason for this.
