c# - Reflecting a WinRT executable from a .Net 4.x App -


in console application; if execute:

assembly.loadfrom(@"c:\...\mywinrtapp.exe")

i get:

system.badimageformatexception occurred hresult=-2147024885 message=could not load file or assembly 'file:///c:\_...\mywinrtapp.exe' or 1 of dependencies. attempt made load program incorrect format. source=mscorlib

is there way around this?

in relation "vyacheslav volkov"'s answer below, step further, thank you. different issue.

"assembly.getexportedtypes()" throws "cannot resolve dependency windows runtime type 'windows.ui.xaml.application'. when using reflectiononly apis, dependent windows runtime assemblies must resolved on demand through reflectiononlynamespaceresolve event."

if try reflectiononlyload referenced assemblies, error:

"could not load file or assembly 'windows, version=255.255.255.255, culture=neutral, publickeytoken=null, contenttype=windowsruntime' or 1 of dependencies. operation not supported. (exception hresult: 0x80131515)".

this related loading winmd references, , explained in post here: could not load file or assembly 'windows, version=255.255.255.255, culture=neutral, publickeytoken=null, contenttype=windowsruntime'.

the full code i'm trying this:

using system.runtime.interopservices.windowsruntime;  var assembly = assembly.reflectiononlyloadfrom(assemblypath);  /*windowsruntimemetadata.reflectiononlynamespaceresolve += (x, y) =>     {         y.namespacename ???         y.resolvedassemblies.add(assembly.reflectiononlyloadfrom(???));         return;     };*/  foreach (var references in assembly.getreferencedassemblies()) {     try     {         assembly.reflectiononlyload(references.fullname);     }     catch (filenotfoundexception)     {         var fi = new fileinfo(assemblypath);         var fi2name = string.format("{0}\\{1}.dll", fi.directoryname, references.name);         var fi2 = new fileinfo(fi2name);          if (fi2.exists)         {             assembly.reflectiononlyloadfrom(fi2.fullname);         }     }     catch (fileloadexception)     {         // when winmd assembly attempted.     } }  return assembly;

any more ideas?

thanks, jon

the latest idea resolves "{windows.ui.xaml, version=255.255.255.255, culture=neutral, publickeytoken=null, contenttype=windowsruntime}".

however, when ".getexportedtypes()" called on "client.exe" assembly, 'reflectiononlynamespaceresolve' event fired once namespace "windows.ui.xaml", resolves "c:\windows\system32\winmetadata\windows.ui.xaml.winmd".

an exception thrown within ".getexportedtypes()", "cannot resolve dependency assembly 'system.runtime, version=4.0.0.0, culture=neutral, publickeytoken=b03f5f7f11d50a3a' because has not been preloaded. when using reflectiononly apis, dependent assemblies must pre-loaded or loaded on demand through reflectiononlyassemblyresolve event.".

if want discover containing types should use assembly.reflectiononlyload method.

assembly.reflectiononlyloadfrom(@"c:\...\mywinrtapp.exe")

update

here's code works me:

appdomain.currentdomain.reflectiononlyassemblyresolve += (sender, eventargs) => assembly.reflectiononlyload(eventargs.name); windowsruntimemetadata.reflectiononlynamespaceresolve += (sender, eventargs) => {     string path =         windowsruntimemetadata.resolvenamespace(eventargs.namespacename, enumerable.empty<string>())             .firstordefault();     if (path == null) return;      eventargs.resolvedassemblies.add(assembly.reflectiononlyloadfrom(path)); };  assembly loadfrom = assembly.reflectiononlyloadfrom(@"c:\....\winrtapp.exe"); type[] types = loadfrom.getexportedtypes(); foreach (type type in types) {     console.writeline(type); }

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
