Unable to load magic1.dll manually in windows about mime HOT 25 CLOSED

This means that you are trying to use x86 dll in x64 proj or vice versa.
If you need x64 dll, then you can get it here Later, I build an assembly for Windows.

from mime.

hmm
I tried both x86 & x64 mode still Unable to load DLL
and the same error :
An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B))

from mime.

@patachi I'm updated the package with windows support (included x64 dll). Now you do not need to install the DLL manually.

from mime.

ohh thank you ^_^

welp i create new classic win form project and added Mime with NuGet (Update Saturday, April 8, 2017 (4/8/2017)) and write a simple code like

    public string TryToGetFileExtension(byte[] fileBuff)
    {
        var fileExtension = "";
        try
        {
            //HeyRed.Mime.MimeGuesser.MagicFilePath = @"magic.mgc";

            var tmpLength = (fileBuff.Length > 512 ? 512 : fileBuff.Length);
            var tmpBuff = new byte[tmpLength];
            Array.Copy(fileBuff, tmpBuff, tmpLength);
            fileExtension = HeyRed.Mime.MimeGuesser.GuessExtension(tmpBuff, tmpBuff.Length);

            tmpBuff = null;
        }
        catch (Exception exp)
        {
            System.Diagnostics.Debug.WriteLine(exp.Message);
        }

        return fileExtension;
    }

and still i got this error :
Unable to load DLL 'libmagic-1': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

from mime.

Hmm, it's very strange. Which windows version you are using? 32 or 64 bit?
Off course I should've be test it with full .net framework.

from mime.

win 10 x64

from mime.

Ok, I have same system.
It seems that problem is that DLL is not copied to output directory.

from mime.

@patachi It's seems like i'm solve that problem. Update package and you will need to set platform x64 in your application.

from mime.

yup it works fine
thanks @hey-red

from mime.

@hey-red Last version (2.3.0) not working for AnyCPU platform.
Current configuration:
Win 10, x64
VS 2017, Platform: AnyCPU

from mime.

@sacerdotu change platform to x64.

from mime.

@hey-red But I need anycpu :) If I change to x64 it will work for sure.

from mime.

@hey-red This is an issue that should be fixed

at HeyRed.Mime.MagicNative.magic_open(MagicOpenFlags flags)
at HeyRed.Mime.Magic..ctor(MagicOpenFlags flags, String dbPath)
at HeyRed.Mime.MimeGuesser.GuessMimeType(String filePath)
at HeyRed.Mime.MimeGuesser.GuessFileType(String filePath)
at MimeHelper.Program.Main(String[] args) in C:\Users\sacerdotu\documents\visual studio 2017\Projects\MimeHelper\MimeHelper\Program.cs:line 28

from mime.

Currently there is no x86 support. Maybe later i'm trying to build 32-bit libmagic, and АnyCPU will be works by default.

from mime.

Perfect. Waiting for the new version!

from mime.

@hey-red Any news?

from mime.

@hey-red uploaded to azure change the application setting to 64bit but problem not solved.
getting this

check the server

but locally its working fine.. what is happening can u help me?

from mime.

@himadrinath
I did not work with azure, but if your app is self contained(contains all dependencies in working dir), then you need to copy libmagic and and other files from win runtime into directory that contains your app.

from mime.

@hey-red i did now i am getting another error

An unhandled exception occurred while processing the request.

BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)

from mime.

Your VM under linux or windows?

from mime.

@hey-red windows

from mime.

@hey-red i found this aspnet/KestrelHttpServer#1625 (comment)

from mime.

Yep, its seems like app run in x86 mode. Also, by default azure VM uses x64 windows?
Change target platform to x64 and publish your app again.

from mime.

@hey-red working on it. lets see what happen. i will inform you the result

from mime.

@hey-red i changed the runtime to win-x64 and deploy to azure now its working fine. thanks for your help
