I'm trying to get a script compiled with Roslyn but whatever I do it keeps complaining about this, at this moment I tried almost everything and have no idea what to try next.
This is the error I get :
'(11,7): error CS0246: The type or namespace name '' could not be found (are you missing a using directive or an assembly reference?)'
It is complaining that the namespace can't be found
I already added the references to the file and even added the assemblies to the InteractiveAssemblyLoader but still no luck.
try
{
#if (DEBUG)
var metadataReferences = ApplicationSettings.Instance.GetValuesAsStringList("Script editor", "MetadataReferences_VOP");
#else
var metadataReferences = ApplicationSettings.Instance.GetValuesAsStringList("Script editor", "MetadataReferences");
#endif
var scriptOptions = ScriptOptions.Default.WithEmitDebugInformation(true);
scriptOptions.AddReferences(metadataReferences);
using var assemblyLoader = new InteractiveAssemblyLoader();
foreach(var reference in metadataReferences)
assemblyLoader.RegisterDependency(Assembly.Load(File.ReadAllBytes(reference)));
scriptRunner = CSharpScript
.Create<string>(script, scriptOptions, typeof(MainGlobals), assemblyLoader)
.ContinueWith("new NewEmail().Main(Email)")
.CreateDelegate();
exception = null;
return true;
}
catch (Exception e)
{
exception = e;
scriptRunner = null;
return false;
}
Is there somebody that has an idea about what to try next?
It seems that the AddReferences returns a new scriptOptions object that is the one with the added references :-)
So the solution was easy, just do this
scriptOptions = scriptOptions.AddReferences(metadataReferences);

I'm following a tutorial to make a game with UE4 and C++ and a error appear when I type the following line
FActorSpawnParameters params;
It says that the identifier FActorSpawnParameters is not defined.
I've tried to modify some of my code but it didn't change...
So I replace all the things in order.
void AUltimatePawn::Shoot()
{
if (BulletClass)
{
FActorSpawnParameters params;
params.SpawnCollisionHandlingOverride = ESpawnActorCollisionHandlingMethod::AlwaysSpawn;
params.bNoFail = true;
params.Owner = this;
params.Instigator = this;
FTransform BulletSpawnTransform;
BulletSpawnTransform.SetLocation(GetActorForwardVector() * 500.f + GetActorLocation());
BulletSpawnTransform.SetRotation(GetActorRotation().Quaternion());
BulletSpawnTransform.SetScale3D(FVector(1.f));
GetWorld()->SpawnActor<ABullet>(BulletClass, BulletSpawnTransform, params);
}
}
I just want you to tell me how to fix this error,
Thank's
Make sure that you include Runtime/Engine/Classes/Engine/World.h.
I extracted this information from the official API reference.
I'm trying to get clang::CompilerInstance to parse a source file which contains an include, but I can't figure out how to get it to actually find the included header. Here is my set up:
std::unique_ptr<clang::CompilerInstance> ci(new clang::CompilerInstance());
ci->createDiagnostics();
LLVMInitializeARMTarget();
LLVMInitializeARMTargetMC();
LLVMInitializeARMAsmPrinter();
LLVMInitializeARMAsmParser();
std::shared_ptr<clang::TargetOptions> options(new clang::TargetOptions);
options->Triple = "arm-v7m-unknown-none-eabi";
options->CPU = "cortex-m3";
clang::TargetInfo *targetInfo = clang::TargetInfo::CreateTargetInfo(ci->getDiagnostics(), options);
ci->setTarget(targetInfo);
ci->createFileManager();
ci->createSourceManager(ci->getFileManager());
NSURL *sysrootURL = [[[NSBundle mainBundle] resourceURL] URLByAppendingPathComponent:#"Compiler/basalt"];
NSURL *includeURL = [sysrootURL URLByAppendingPathComponent:#"include"];
ci->createPreprocessor(clang::TranslationUnitKind::TU_Complete);
ci->getPreprocessorOpts().UsePredefines = false;
// Header searcher
llvm::IntrusiveRefCntPtr<clang::HeaderSearchOptions> hso(new clang::HeaderSearchOptions());
hso->UseBuiltinIncludes = false;
hso->UseStandardSystemIncludes = false;
hso->UseStandardCXXIncludes = false;
hso->Sysroot = [[includeURL path] UTF8String];
clang::HeaderSearch headerSearch(hso, ci->getSourceManager(), ci->getDiagnostics(), ci->getLangOpts(), targetInfo);
headerSearch.AddSearchPath(clang::DirectoryLookup(ci->getFileManager().getDirectory([[includeURL path] UTF8String]), clang::SrcMgr::C_System, false), true);
clang::InitializePreprocessor(ci->getPreprocessor(), ci->getPreprocessorOpts(), ci->getFrontendOpts());
// Main file
const clang::FileEntry *file = ci->getFileManager().getFile([[[_url URLByAppendingPathComponent:#"src/main.c"] path] UTF8String]);
ci->getSourceManager().setMainFileID(ci->getSourceManager().createFileID(file, clang::SourceLocation(), clang::SrcMgr::C_User));
ci->getPreprocessor().EnterMainSourceFile();
ci->getDiagnosticClient().BeginSourceFile(ci->getLangOpts(), &ci->getPreprocessor());
clang::Token tok;
do {
ci->getPreprocessor().Lex(tok);
if(ci->getDiagnostics().hasErrorOccurred())
break;
ci->getPreprocessor().DumpToken(tok);
std::cerr << std::endl;
} while(tok.isNot(clang::tok::eof));
ci->getDiagnosticClient().EndSourceFile();
The paths are definitely 100% correct and checked them over and over again. It all works up until the point the source code I throw at it contains something like #include <foobar.h>, in which case it will fail with error 'foobar.h' file not found, even though foobar.h is definitely there. I feel like I'm missing something really obvious here. Any pointers into the right direction?
Firstly, drop using CompilerInstance- the ownership semantics are so bad it's practically unusable (unless they fixed that in 3.6 with unique_ptr). It's easier to simply make the components yourself.
Secondly, yes, you have to do it yourself. Here's a verbatim excerpt from my own project that uses Clang:
clang::HeaderSearch hs(/*params*/);
// WHY AM I DOING THIS MYSELF CLANG
// CAN'T YOU READ YOUR OWN CONSTRUCTOR PARAMETERS AND OPTIONS STRUCTS?
std::vector<clang::DirectoryLookup> lookups;
for (auto entry : opts.HeaderSearchOptions->UserEntries) {
auto lookup = clang::DirectoryLookup(FileManager.getDirectory(entry.Path), clang::SrcMgr::CharacteristicKind::C_System, false);
if (!lookup.getDir())
throw SpecificError<ClangCouldNotInterpretPath>(a, where, "Clang could not interpret path " + entry.Path);
lookups.push_back(lookup);
}
hs.SetSearchPaths(lookups, 0, 0, true);
I'm really suffering through the WinRT Windows::Storage namespace with all it's asyncronousness.
I have the following private members in my header file:
//Members for copying the SQLite db file
Platform::String^ m_dbName;
Windows::Storage::StorageFolder^ m_localFolder;
Windows::Storage::StorageFolder^ m_installFolder;
Windows::Storage::StorageFile^ m_dbFile;
And I have the following code block in my implementation file:
//Make sure the SQLite Database is in ms-appdata:///local/
m_dbName = L"DynamicSimulations.db";
m_localFolder = ApplicationData::Current->LocalFolder;
m_installFolder = Windows::ApplicationModel::Package::Current->InstalledLocation;
auto getLocalFileOp = m_localFolder->GetFileAsync(m_dbName);
getLocalFileOp->Completed = ref new AsyncOperationCompletedHandler<StorageFile^>([this](IAsyncOperation<StorageFile^>^ operation, AsyncStatus status)
{
m_dbFile = operation->GetResults();
if(m_dbFile == nullptr)
{
auto getInstalledFileOp = m_installFolder->GetFileAsync(m_dbName);
getInstalledFileOp->Completed = ref new AsyncOperationCompletedHandler<StorageFile^>([this](IAsyncOperation<StorageFile^>^ operation, AsyncStatus status)
{
m_dbFile = operation->GetResults();
m_dbFile->CopyAsync(m_localFolder, m_dbName);
});
}
});
I get a memory access violation when it gets to m_dbFile = operation->GetResults();
What am I missing here? I come from a c# background in which this is really easy stuff to do :/
I've tried using '.then' instead of registering the event but I couldn't even get those to compile.
thank you for your help!
If you are interested in the WinRT solution, here it is:
It seems all you want to do is to copy the DB file from the installed location into the local folder. For that the following code should suffice:
//Make sure the SQLite Database is in ms-appdata:///local/
m_dbName = L"DynamicSimulations.db";
m_localFolder = ApplicationData::Current->LocalFolder;
m_installFolder = Windows::ApplicationModel::Package::Current->InstalledLocation;
create_task(m_installFolder->GetFileAsync(m_dbName)).then([this](StorageFile^ file)
{
create_task(file->CopyAsync(m_localFolder, m_dbName)).then([this](StorageFile^ copiedFile)
{
// do something with copiedFile
});
});
I've tried this thing before. Don't do this:
if(m_dbFile == nullptr)
Instead verify the value of "status".
if(status == AsyncStatus::Error)
I get the following error when I try to execute the code below.
Uncaught TypeError: Object true has no method 'dartObjectLocalStorage$getter'
I started a Web Application in Dart Editor Version 0.1.0.201201150611 Build 3331. Here is the complete code for the lone dart file. The if statement that results in the error is commented below.
#import('dart:html');
class Test3D {
CanvasElement theCanvas;
WebGLRenderingContext gl;
static String vertexShaderSrc = """
attribute vec3 aVertexPosition;
void main(void) {
gl_Position = vec4(aVertexPosition, 1.0);
}
""";
Test3D() {
}
void run() {
write("Hello World!");
// Set up canvas
theCanvas = new Element.html("<canvas></canvas>");
theCanvas.width = 100;
theCanvas.height = 100;
document.body.nodes.add(theCanvas);
// Set up context
gl = theCanvas.getContext("experimental-webgl");
gl.clearColor(0.5, 0.5, 0.5, 1.0);
gl.clear(WebGLRenderingContext.COLOR_BUFFER_BIT);
WebGLShader vertexShader = gl.createShader(WebGLRenderingContext.VERTEX_SHADER);
gl.shaderSource(vertexShader, vertexShaderSrc);
gl.compileShader(vertexShader);
// Adding this line results in the error: Uncaught TypeError: Object true has no method 'dartObjectLocalStorage$getter
var wasSuccessful = gl.getShaderParameter(vertexShader, WebGLRenderingContext.COMPILE_STATUS);
}
void write(String message) {
// the HTML library defines a global "document" variable
document.query('#status').innerHTML = message;
}
}
void main() {
new Test3D().run();
}
I'm really keen on dart and would appreciate any help you could give me on this.
Here is the console output for the error:

The error indicates that somewhere in your code the field 'dartObjectLocalStorage' is accessed on the boolean true. The given code-snippet does not contain this identifier and is thus probably not responsible for the error.
It could be that the error-reporting gives the wrong line number (potentially even the wrong file).
To debug this:
try to find a reference to 'dartObjectLocalStorage' in your code.
try to find a reference to 'dartObjectLocalStorage$getter' in the generated code.
run on the VM or compile with a different compiler (frogc vs dartc).
good luck.
According to the documentation for WebGLRenderingContext the return type is Object, if you know the object is bool you can just use it as a bool or dynamic
var v=gl.getShaderParameter(vertexShader, WebGLRenderingContext.COMPILE_STATUS)
or more explicitly
var v=gl.getShaderParameter(vertexShader, WebGLRenderingContext.COMPILE_STATUS).dynamic
and then use it in your conditional statement. Also try compiling it with frogc rather than the build in JavaScript compiler, it usually results in better errors.
Using ColdFusion 9.01, occasionally, we have observed an issue where an error may be occurring within a CFC function and when we attempt to add writeDump(foo); and abort; calls to debug the error ColdFusion does not honor those calls.
Example:
private void function index(Event)
{
var rc = Event.getCollection();
var prc = Event.getCollection(private=true);
/** NOT HONORED! **/
writeDump(var=rc);
abort;
prc.JSON = {};
prc.JSON.show = variables.APIProxy.call(
handler = 'shows'
,action = 'read'
,event = arguments.Event
/** THE ERROR IS OCCURING HERE **/
,params = { language=lcase(rc.language.getLanguage_Medium()), show=rc.show_name }
);
prc.JSON.showEpisodes = variables.APIProxy.call(
handler = 'episodes'
,action = 'index'
,event = arguments.Event
,params = { language=lcase(rc.language.getLanguage_Medium()), show=rc.show_name, detail=true }
);
prc.JSON.products = variables.APIProxy.call(
handler = 'products'
,action = 'index'
,event = arguments.Event
,params = { language=lcase(rc.language.getLanguage_Medium()), detail=true }
);
Event.addAssets(
'model/product.js
,model/show.js
,collection/product_mobile.js
,collection/show_mobile.js
,view/product_mobile.js
,view/productList.js
,view/show_mobile.js
,view/showList.js
,model/episode.js
,view/episode_mobile.js
,view/episodeList.js
,collection/episode_mobile.js
,collection/product_mobile.js
,mobile/episodeObject.css
,mobile/show.js
,mobile/show.css
,mobile/category.css
');
Event.setLayout('layout.mobile');
Event.setView("show/index_mobile");
return;
}
I believe we have successfully eliminated caching. I am curious if anyone else has encountered this.
Thank you.

I'm guessing that the error is a parse error, not a true runtime error, so it gets thrown before the function actually executes. It's not actually skipping over your abort, it just fails to parse (or execute) the entire thing.
I'm not sure why you're getting a parse error there, but I do know the CF code that handles struct literals is somewhat flaky.
The issue was with the struct literals declared within the argument calls to a function.
i'm going to go out on a limb here and say that your issue might have something to do with this bug:
http://cfbugs.adobe.com/cfbugreport/flexbugui/cfbugtracker/main.html#bugId=86960
is there anything in your app that executes in the onRequestEnd() method?
it would be helpful to tell us what exactly is happening and/or the output you're getting when the issue happens.
