Evidence for Assembly.LoadFrom Ryan Cromwell11-Sep-02 4:38 Ryan Cromwell 11-Sep-02 4:38  Can someone help me understand the Evidence objects as they pertain to Assembly.LoadFrom. I'd like to be able to load Assemblies from a file share or mapped drive, but have security issues. I'm not sure how to use the Evidence to do this or if I can really, but before I go flinging code I'd like some knowledge. Re: Evidence for Assembly.LoadFrom Ryan Cromwell11-Sep-02 4:52 Ryan Cromwell 11-Sep-02 4:52  ya so apparently it is working... I'd still like to understand how it works and how to use it because it does not work with file shares (ie file://\\server\assemblies\asdf.dll).

Reloading explorer.exe Eka11-Sep-02 1:57 Eka 11-Sep-02 1:57  Hi all, It seems irrelavant forum if i ask this question here, but since i use C# i think i can get help from here. Question is, how to reloading/refreshing/restarting explorer.exe from C#? What i like to do is, after editing explorer-related registry, i don't want to restart my computer, but instead, i just want to refresh the explorer.exe so it can read the registry back. Or, maybe there is another method/way to refresh the registry in general? Target machine is Win 98 Re: Reloading explorer.exe Rickard Andersson2011-Sep-02 2:34 Rickard Andersson20 11-Sep-02 2:34  I don't think at all that's possible... It shouldn't be so...

Re: Reloading explorer.exe Jason Gerard12-Sep-02 7:57 Jason Gerard 12-Sep-02 7:57  If you are using Windows 2k or XP, open up the Task Manager, click the Processes tab, click explorer.exe and thick click End Process. The task bar will dissapear along with your desktop, Task Manager will stay open. Sometimes explorer.exe will restart, not always though. So go to the File menu and to New Task (Run...) In the box type explorer.exe and click OK. Your desktop should reload. Also useful if the shell crashes and you don't want to restart b/c you have a lot of programs open. Jason Gerard how to load a dll at runtime fftongzhi10-Sep-02 21:39 fftongzhi 10-Sep-02 21:39  I write a class and build it in a dll.I used it in a application.And then I changed my code in some function,and rebuilded it. Now I need change the dll at runtime,how to do this. At win32,it will be "loadlibrary"and "freelibrary",at .net，？？？？？ In addition,I didn't change define of the class. lost my way Re: how to load a dll at runtime Nish Nishant10-Sep-02 22:04 Nish Nishant 10-Sep-02 22:04  See :- http://www.codeproject.com/managedcpp/mcppdynamdll.asp It's for MC++, but you can convert to C# easily I guess Nish Author of the romantic comedy Summer Love and Some more Cricket [New Win] Review by Shog9 Click here for review[NW] Re: how to load a dll at runtime fftongzhi10-Sep-02 22:46 fftongzhi 10-Sep-02 22:46  yes ,it can load a dll,but I will overwrite a dll.That means I must unload the dll first,and then overwrite it ,and load it again. but use assembly ,you can only load a dll,can't unload it.I cann't change the using dll. ???? lost my way Re: how to load a dll at runtime leppie10-Sep-02 23:54 leppie 10-Sep-02 23:54  fftongzhi wrote: but use assembly ,you can only load a dll,can't unload it. Unfortunately , the only way to unload an assembly is to unload the appdomain. You will need to load the assembly in a different AppDomain to succeed with your problem. Look at the Supergraph Calculator example on MSDN by Eric Gunnerson (2 parts). I have attempted this , and failed miserably. So good luck. Re: how to load a dll at runtime fftongzhi11-Sep-02 0:13 fftongzhi 11-Sep-02 0:13  Let me try............................. lost my way Re: how to load a dll at runtime fftongzhi11-Sep-02 20:47 fftongzhi 11-Sep-02 20:47  Very unfortunately,it don't work either. It is my codes. AppDomain appDomain = AppDomain.CreateDomain("mydomain"); Assembly a = appDomain.Load("dlltochange"); Type t = a.GetType("dlltochange.Class1"); MethodInfo mi = t.GetMethod("showstring"); object[] parameter=new object[1]; parameter[0]="hello world"; object obj = Activator.CreateInstance(t); mi.Invoke(obj,parameter); AppDomain.Unload(appDomain); dlltochange is a dll,have Class1 in it,showstring is a function of Class1. I called the unload,and the dll is in use yet. And I cann't move the dll to another directory.the parameter of load method can not accept a file name with path. Will I fail ultimately? Is this a limitation of .net ??? lost my way Re: how to load a dll at runtime Paul Riley11-Sep-02 23:35 Paul Riley 11-Sep-02 23:35  I'm sure there must be a better way but as a workaround, can't you just "DllImport" LoadLibrary and FreeLibrary into your program? Paul Re: how to load a dll at runtime fftongzhi12-Sep-02 1:24 fftongzhi 12-Sep-02 1:24  And can it load a .net dll? Are you sure? lost my way Re: how to load a dll at runtime Paul Riley12-Sep-02 1:31 Paul Riley 12-Sep-02 1:31  Nah... course I'm not sure. But are you sure it won't?

Just try, try again Re: how to load a dll at runtime fftongzhi12-Sep-02 3:58 fftongzhi 12-Sep-02 3:58  Before a hard try,find a broad way is important.Do you think so?

Have you tried the shadow path, as far as I remember the app will load the assembly in some randon generated directory? Also, if I remember correctly, Eric makes use of a loader assembly. I cant remmeber the details though Good luck Re: how to load a dll at runtime fftongzhi13-Sep-02 0:03 fftongzhi 13-Sep-02 0:03  Is that AppDomain.SetCachePath(string)?? It doesn't work too. yes ,Eric made a loader,but what is the key?? lost my way Re: how to load a dll at runtime leppie13-Sep-02 0:11 leppie 13-Sep-02 0:11  fftongzhi wrote: Is that AppDomain.SetCachePath(string)?? No You need to set this via AppDomainSetup in AppDomain.CreateDomain(). I think it has to be done via that function else it will not function.
