No, you cannot stop the .NET framework. This would even be dangerous, as it would halt the execution of all applications that are using the framework.

Can you tell us what you're trying to achieve? Perhaps there's an alternative method to reach that goal. If the target is a Windows Service, then yes - those can be paused, started and stopped.

How To Get latest Installed Version of .Net and What Happens If...

I'm trying to get the latest installed version of .Net on a given machine. I've tried a couple of different ways, but it keeps coming back with 2.0, which is curious since I'm running a WPF app on a machine that I *KNOW* has 3.5 SP1 on it.

How should I go about properly retrieving the .Net version?

What happens if a .Net app is run on a system that doesn't have the appropriate version of .Net?

Davey's reply covers the first part of your question. More info about the entire detection process could be found here.

As for what happens, in general the program will crash on startup, normally with an incredibly useless message. If you have 2.0 and need 3.0 or 3.5 then it will sometimes crash saying it could not find PresentationFramework.dll or whatever WPF one it is looking for.

Hi Sam,

It could be that you haven't included Microsoft Excel 11.0 Object Library.

But using Excel Automation is very complicated. Maybe you should try some 3rd party component. GemBox has .NET Excel component that makes programing with Excel in C# and VB much easier then Excel Automation. It also doesn't require you to have installed Microsoft Excel on computer that runs your application, it works with most spreadsheet files (xls,csv,xlsx,html) and it's free for commercial use if you need less then 150 rows.

Locating a server without ip address.

Hi
I created a client and server app. using Sockets, is there a way that the client can locate the listening server without knowing the server IP Address in C#/VB.NET?

It needs some way to locate the server. It could be a domain name or subdomain e.g. http://myserver.mydomain.com. This will resolve via DNS to an IP address assuming the DNS is configured correctly.

Hi,
My application is designed in .net framework 2.0 which is working fine with 4+ client with more then 1000+ users.

But in one client environment application is closing suddenly without giving any error message or event in event log.

We have UI +Web services +DB layers. All are developed in .framework 2.0.
Right now in client environment in IIS7 my application is running. And in user machines
Framework 2.0, 3.0, 3.5 is there becoz of windows updates.

Any one can guess what could be the problem application is closing randomly.
There is no timeframe when application close.

Regards,
Pritesh

hello,everyone. I have come to the follow question.
A file from Host (AS/400 or IBM 9000) in EBCDIC(ibm 1388 or cp935) encode , include some chinese chars.
Now, I would translate the string in this file to chinese chars in Windows OS and .net Framework, which is gb2312 encode. I have search many archives, but can't find a way.
Please help me ! Thanks.

hope for help

A quick scan of google brings up a product called TextPipe Pro which claims to do it. Not sure if that helps you or not but it might be worth looking at if all else fails.

TextPipe is a software, not source code. I need a way to translate the code in .net framework.
thank you , anyway.

A quick scan of google brings up some examples of converting between GB2312 and unicode.

static void Main(string[] args) {
    string infile = args[0];
    string outfile = args[1];
    using (StreamReader sr = new StreamReader(infile, Encoding.GetEncoding(936))) {
        using (StreamWriter sw = new StreamWriter(outfile, false, Encoding.UTF8)) {
            sw.Write(sr.ReadToEnd());
            sw.Close();
        }
        sr.Close();
    }
}

It shouldn't be too hard to start from that and figure out how to convert from EBCDIC.

This can only trans 936 to Utf8, can't translate 1388 to 936.

By the way you supply, we can only translate IBM EBCDIC 037 or 500 to 936(gb2312), but can't translate the 1388 encode. I think it maybe the there is not the 1388 encode in the EcodeInfo class. Why .net doesn't supply this??? Confused | :confused:

Dear All,
I have installed Vista OS and .Net 2.0 .. and .Net 3.5 in my computer,
I am really interested to know which services are dependant to .Net 2.0 and .Net 3.5?
I mean all services for both network connection, applications and what ever relays to .Net framework.
