why the chinese words is chaos in monotouch/ios7 - unicode

ios7/xamarin studio 4.3/monotouch7.2:
it's just a simply static method return the human-readable message, but why the chinese words is chaos in monotouch/ios7 ( in debug-watch window & iphone UI)
I have been attached the iPhone snapshot,
and uploaded the project solution file, pls download it from: http://pan.baidu.com/s/1o69G8xs
thanks for your help.
the source code is:
public static string GetMsg()
{
//btw, this file was edited in microsoft visual studio 2013
//and shared to mac to compile&debug
//(my business logic code is edit by vs2013)
return "Please input mobileNo, chinese words is(but incorrect to display):" + "请输入手机号";
}
public override void ViewDidLoad()
{
base.ViewDidLoad();
string msg = TestLib.TestClass.GetMsg();
UIAlertView alertDialog = new UIAlertView("", msg, null, "OK");
alertDialog.Show();
}

UPDATE
It turned out to be the source file encoding (ISO-8859) versus UTF8.
The hint was that copying the code to another file made this work as expected.
ORIGINAL
I'm not sure for the Xamarin Studio debugger (it could be a different issue) but this should work in your iPhone user interfaces.
Have you included the additional I18N assemblies (in the project options) ?
If so the please file a bug report (and attach a sample app) so we can look why the UI does not show up correctly in your application.

WordprocessingDocument.CreateFromTemplate method creates corrupted MS Word files

I have proper .dotm template.
When I create a new file based on a template by double clicking in explorer it creates the correct file (based on this template). Created file size after save is 16Kb (without any content).
But if I want to use .CreateFromTemplate method in my code I cannot open a newly created .docx file in MS Word.
New file size is 207Kb (just like .dotm file). MS Word display "run-time error 5398" and not open the file.
I'm using nuget package DocumentFormat.OpenXml 2.19.0, Word 365 version 16.0.14931.20648 - 32bit and code like this:
using (WordprocessingDocument doc = WordprocessingDocument.CreateFromTemplate(templatePath))
{
doc.SaveAs(newFileName);
}
Google is silent about this error, ChatGPT says that:
The "Run-time Error 5398" error means that the file you are trying to open is corrupted or not a valid docx file. Possible reasons for this error may be the following:
The file was not saved correctly after making changes. Verify that the Save() method was called after making changes to the file.
The file was saved with the wrong extension, e.g. as DOTM instead of DOCX
The file was saved in an invalid format.
There may have been some unhandled exceptions in your code.
When I manually change the extension of a new file from docx to dotm, there is no error when opening, but the file does not open.
What am I doing wrong with CreateFromTemplate method?
I tried to reproduce the behavior you described, using the following unit tests:
public sealed class CreateFromTemplateTests
{
private readonly ITestOutputHelper _output;
public CreateFromTemplateTests(ITestOutputHelper output)
{
_output = output;
}
[Theory]
[InlineData("c:\\temp\\MacroEnabledTemplate.dotm", "c:\\temp\\MacroEnabledDocument.docm")]
[InlineData("c:\\temp\\Template.dotx", "c:\\temp\\Document.docx")]
public void CanCreateDocmFromDotm(string templatePath, string documentPath)
{
// Let's not attach the template, which is done by default. If a template is attached, the validator complains as follows:
// The element has unexpected child element 'http://schemas.openxmlformats.org/wordprocessingml/2006/main:attachedTemplate'.
using (var wordDocument = WordprocessingDocument.CreateFromTemplate(templatePath, false))
{
// Validate the document as created with CreateFromTemplate.
ValidateOpenXmlPackage(wordDocument);
// Save that document to disk so we can open it with Word, for example.
wordDocument.SaveAs(documentPath).Dispose();
}
using (WordprocessingDocument wordDocument = WordprocessingDocument.Open(documentPath, true))
{
// Validate the document that was opened from disk, just to see what Word would open.
ValidateOpenXmlPackage(wordDocument);
}
}
private void ValidateOpenXmlPackage(OpenXmlPackage openXmlPackage)
{
OpenXmlValidator validator = new(FileFormatVersions.Office2019);
List<ValidationErrorInfo> validationErrors = validator.Validate(openXmlPackage).ToList();
foreach (ValidationErrorInfo validationError in validationErrors)
{
_output.WriteLine(validationError.Description);
}
if (validationErrors.Any())
{
// Note that Word will most often be able to open the document even if there are validation errors.
throw new Exception("The validator found validation errors.");
}
}
}
In both tests, the documents are created without an issue. Looking at the Open XML markup, both documents look fine. However, while I don't get any runtime error, Word also does not open the macro-enabled document.
I am not sure why that happens. It might be related to your security settings.
Depending on whether or not you really need to use CreateFromTemplate(), you could create a .docm (rather than a .dotm) and create new macro-enabled documents by copying that .docm.
I opened an issue in the Open XML SDK project on GitHub.

Visual Studio Extension: Project context is applied to every opened file except the first one

I have a Visual Studio extension package where I am applying C++ syntax settings to custom file extensions. This is done in the Visual Studio's Text Editor options. Those files are plain text and I mean to have them behave as code files in the IDE (IntelliSense, find matching braces, etc...)
It's mostly working fine, but there is one problem. The C++ syntax context is not applied to whichever is the first file I open in a given Visual Studio session. I will launch Visual Studio, open one of our custom projects, and open one file. The IDE opens a document window and the file is opened, can be edited and saved, no problem in appearance. But the file behaves as a plain text and not a C++ source. Now, whenever I open a second file in the IDE, or any further file, the C++ settings do get applied successfully. I can close all document tabs, and open new ones, and all those tabs are fine. Even re-opening the first file in a new tab, or after re-loading the project or the solution, is fine. Only the first document opened in a Visual Studio session has the issue.
For the following segment, I will refer to the Microsoft documentation on using their standard editor: https ://msdn.microsoft.com/en-us/library/bb166504.aspx
To implement the OpenItem method with a standard editor
1.Call IVsRunningDocumentTable (RDT_EditLock) to determine whether the document data object file is already open.
2.If the file is already open, resurface the file by calling the IsDocumentOpen method, specifying a value of IDO_ActivateIfOpen for the grfIDO parameter.
If the file is open and the document is owned by a different project than the calling project, your project receives a warning that the editor being opened is from another project. The file window is then surfaced.
3.If the document is not open or not in the running document table, call the OpenStandardEditor method (OSE_ChooseBestStdEditor) to open a standard editor for the file.
When you call the method, the IDE performs the following tasks:
a.The IDE scans the Editors/{guidEditorType}/Extensions subkey in the registry to determine which editor can open the file and has the highest priority for doing this.
b.After the IDE has determined which editor can open the file, the IDE calls CreateEditorInstance. The editor's implementation of this method returns information that is required for the IDE to call CreateDocumentWindow and site the newly opened document.
c.Finally, the IDE loads the document by using the usual persistence interface, such as IVsPersistDocData2.
d.If the IDE has previously determined that the hierarchy or hierarchy item is available, the IDE calls GetItemContext method on the project to get a project-level context IServiceProvider pointer to pass back in with the CreateDocumentWindow method call.
4.Return an IServiceProvider pointer to the IDE when the IDE calls GetItemContext on your project if you want to let the editor get context from your project.
Performing this step lets the project offer additional services to the editor.
If the document view or document view object was successfully sited in a window frame, the object is initialized with its data by calling LoadDocData.
It definitely seems to me that I need to hit element (D) from the above instructions. I have debuged through my extension code, and I do see where my implementation of GetItemContext() comes into play. When I open most files, the code path does effectively go through this method, however it does not when I open the first file of a Visual Studio session.
Call stack from OpenStandardEditor
GetItemContext is invoked by the Microsoft assemblies and I do not know what is the condition that triggers whether it is called or not. I can only trace up to my call to the method OpenStandardEditor(), in FileDocumentManager.cs, then I don't know what happens beyond that. The above screenshot is the call stack when GetItemContext is successfully invoked, but when I'm opening the first file I'm totally in the dark as to what OpenStandardEditor is doing. I do know that in both cases, when the context is loaded and when it is not, the exact same parameter values are passed to OpenStandardEditor. So here's my code where this method is invoked, if that can be of some help:
My override of class DocumentManager:
private int Open(bool newFile, bool openWith, uint editorFlags, ref Guid editorType, string physicalView, ref Guid logicalView, IntPtr docDataExisting, out IVsWindowFrame windowFrame, WindowFrameShowAction windowFrameAction)
{
windowFrame = null;
if (this.Node == null || this.Node.ProjectMgr == null || this.Node.ProjectMgr.IsClosed)
{
return VSConstants.E_FAIL;
}
int returnValue = VSConstants.S_OK;
string caption = this.GetOwnerCaption();
string fullPath = this.GetFullPathForDocument();
// Make sure that the file is on disk before we open the editor and display message if not found
if (!((FileNode)this.Node).IsFileOnDisk(true))
{
// Inform clients that we have an invalid item (wrong icon)
this.Node.OnInvalidateItems(this.Node.Parent);
// Bail since we are not able to open the item
return VSConstants.E_FAIL;
}
IVsUIShellOpenDocument uiShellOpenDocument = this.Node.ProjectMgr.Site.GetService(typeof(SVsUIShellOpenDocument)) as IVsUIShellOpenDocument;
IOleServiceProvider serviceProvider = this.Node.ProjectMgr.Site.GetService(typeof(IOleServiceProvider)) as IOleServiceProvider;
try
{
int result = VSConstants.E_FAIL;
if (openWith)
{
result = uiShellOpenDocument.OpenStandardEditor((uint)__VSOSEFLAGS.OSE_UseOpenWithDialog, fullPath, ref logicalView, caption, this.Node.ProjectMgr, this.Node.ID, docDataExisting, serviceProvider, out windowFrame);
}
else
{
__VSOSEFLAGS openFlags = 0;
if (newFile)
{
openFlags |= __VSOSEFLAGS.OSE_OpenAsNewFile;
}
//NOTE: we MUST pass the IVsProject in pVsUIHierarchy and the itemid
// of the node being opened, otherwise the debugger doesn't work.
if (editorType != Guid.Empty)
{
result = uiShellOpenDocument.OpenSpecificEditor(editorFlags, fullPath, ref editorType, physicalView, ref logicalView, caption, this.Node.ProjectMgr, this.Node.ID, docDataExisting, serviceProvider, out windowFrame);
}
else
{
openFlags |= __VSOSEFLAGS.OSE_ChooseBestStdEditor;
// THIS IS THE CALL THAT I'M ALWAYS INVOKING. PARAMS ARE ALWAYS THE SAME, BUT ITEM CONTEXT IS NOT ACTIVATED FOR FIRST FILE OF A SESSION.
result = uiShellOpenDocument.OpenStandardEditor((uint)openFlags, fullPath, ref logicalView, caption, this.Node.ProjectMgr, this.Node.ID, docDataExisting, serviceProvider, out windowFrame);
}
}
if (result != VSConstants.S_OK && result != VSConstants.S_FALSE && result != VSConstants.OLE_E_PROMPTSAVECANCELLED)
{
ErrorHandler.ThrowOnFailure(result);
}
if (windowFrame != null)
{
object var;
if (newFile)
{
ErrorHandler.ThrowOnFailure(windowFrame.GetProperty((int)__VSFPROPID.VSFPROPID_DocData, out var));
IVsPersistDocData persistDocData = (IVsPersistDocData)var;
ErrorHandler.ThrowOnFailure(persistDocData.SetUntitledDocPath(fullPath));
}
var = null;
ErrorHandler.ThrowOnFailure(windowFrame.GetProperty((int)__VSFPROPID.VSFPROPID_DocCookie, out var));
this.Node.DocCookie = (uint)(int)var;
if (windowFrameAction == WindowFrameShowAction.Show)
{
ErrorHandler.ThrowOnFailure(windowFrame.Show());
}
else if (windowFrameAction == WindowFrameShowAction.ShowNoActivate)
{
ErrorHandler.ThrowOnFailure(windowFrame.ShowNoActivate());
}
else if (windowFrameAction == WindowFrameShowAction.Hide)
{
ErrorHandler.ThrowOnFailure(windowFrame.Hide());
}
}
}
catch (COMException e)
{
Trace.WriteLine("Exception e:" + e.Message);
returnValue = e.ErrorCode;
this.CloseWindowFrame(ref windowFrame);
}
return returnValue;
}
I have also tried an alternative. In the call stack where I perform DoDefaultAction on my FileNode (extends HierarchyNode), I normally call an instance of my DocumentManager.Open() directly. I have changed that to try OpenDocumentViaProject() instead. Now, the MSENV assembly turns out to call my GetItemContext, then goes out to my implementation of DocumentManager.Open I quoted above.
Call stack from OpenDocumentViaProject
Sounds promising... but no. Beyond the screenshot above, once I call OpenStandardEditor the exact same behavior happens. No project context is applied to the first document opened in a session, and the context is applied to every further file. The call to GetItemContext() that is done by OpenDocumentViaProject() does not seem to matter in the slightest. Only when OpenStandardEditor() also ends up calling GetItemContext() somewhere downstream does the project settings I want get applied.
I don't see where I would be doing something fundamentally wrong. It seems to me that I am following the Mimcrosoft instructions on opening standard editors. Would you have a clue as to how my GetItemContext implementation is not invoked when I'm opening the first file of a VS session? Thanks

Eclipse: Select text in XSD programmatically from plugin

I'm currently writing an Eclipse plugin. In it, I want to programmatically open an editor and select a portion of the text. The opened file does not have to be imported into the workspace (that's why I'm using IFileStore in the code below).
I'm using code similar to this:
IFileStore fileStore = EFS.getLocalFileSystem().getStore(localPath);
IEditorPart part = IDE.openEditorOnFileStore(page, fileStore);
final int posStart = ...;
final int posEnd = ...;
part.getEditorSite().getSelectionProvider().setSelection(
new TextSelection(posStart, posEnd - posStart));
For Java files it works fine, but for XML Schema (XSD), it doesn't. The editor opens, but no text is selected.
From debugging, I can tell that the part is of type org.eclipse.wst.xsd.ui.internal.editor.InternalXSDMultiPageEditor, and the selection manager is an org.eclipse.wst.xsd.ui.internal.adt.editor.CommonSelectionManager
I'm targetting Eclipse Mars and Neon, it does not seem to work for both.
What can I do to make it work? Or at least find some further information?
After having a look at the WTP code, this does not seem to be supported at the moment. But I found a workaround by explicitly checking if the editor is a multi part editor:
private static void setSelection(IEditorPart part, TextSelection textSelection) {
if (part instanceof MultiPageEditorPart) {
final MultiPageEditorPart multiPage = (MultiPageEditorPart) part;
for (final IEditorPart subPart : multiPage.findEditors(multiPage.getEditorInput())) {
setSelection(subPart, textSelection);
}
} else {
part.getEditorSite().getSelectionProvider().setSelection(textSelection);
}
}
I was not sure whether it is better to send the selection to all sub parts or only to one specific, but so far sending it to all seems to work.

How to read the source content-type from each Eclipse file?

I have an Eclipse project that contains several source files, with a bunch of different encodings: some files are UTF8, some others are ISO-8859-1, others more are windows-1252.
Moreover, there are files whose encoding is explicit (it can bee seen in each file Properties window) while that of others is Inherited from container.
I need to convert them to UTF8 - and I've already found I can use iconv for that - see my answer here for details -, but since they're more than one thousand, I can't convert them one by one: is there any programmatic way to get the encoding from the IDE or something similar?
I'm on Windows, I may do some shell scripting and / or write auxiliary software.
The charset setting of project file could be found in ${PROJECT_FOLDER}/.settings/org.eclipse.core.resources.prefs
Since there are so many files in your project. Create a simple Eclipse plugin could reduce the effort. Here are the steps:
Select Eclipse menu item New > Project... > Plug-in Project
Accept default values and goto last page, choose Hello, World template.
Open and edit plugin.xml, adding required plugin org.eclipse.core.resources in Dependencies page.
Edit SampleAction.java, refer the sample code below..
Create a Debug Configuration for execute Eclipse Application.
Start the eclipse and import your project.
Select menu item Sample Menu to invoke public void run(IAction action).
Sample code of Eclipse resource API:
//import org.eclipse.core.resources.*;
//import org.eclipse.core.runtime.*;
public void run(IAction action) {
final boolean keepHistory = true;
IProject project = ResourcesPlugin.getWorkspace().getRoot().getProject("yourProjectName");
project.accept(new IResourceVisitor() {
public boolean visit(IResource resource) {
IFile file = (IFile)resource;
try {
String charset = file.getCharset(true);
if (!"UTF-8".equals(charset)) {
InputStream is = file.getContents();
//convert to UTF-8 and save it
String str = new String(IOUtils.toByteArray(is), charset);
file.setContents(new ByteArrayInputStream(str.getBytes("UTF-8")), true, keepHistory, null);
//remove charset setting
file.setCharset("UTF-8", null);
}
} catch (Throwable e) {
//log error... maybe process later via project.getFile(new Path(projectRelativePath))
Activator.getDefault().getLog().log(new Status(IStatus.INFO, Activator.PLUGIN_ID,
file.getProjectRelativePath().toString(), e));
}
return false;
}
}, IResource.DEPTH_INFINITE, IResource.FILE);
}

HTML5 Offline GWT APP

I am trying to build a offline gwt app using HTML5 cache manifest and
local storage, but to do that, i need to build the manifest file
listing all the GWT generated files, right?
Can i do this during the compile process or is it better to do this in
a shell script?
This should be done using a Linker, so that your resources are automatically added to the manifest at compile time. I know there exists an HTML5 cache manifest linker, since the GWT team has mentioned it a few times, but I don't know where the source is.
The closest alternative (and probably a good starting point for writing an HTML5 linker) is the Gears offline linker. Gears' offline manifests are pretty similar to HTML5's, so it's probably a matter of changing a few lines to make it work.
There's also an informative video about using GWT linkers to have your app take advantage of HTML5 Web Workers.
I just had to do this other day at work. Like the previous answer says, you just need to add a linker. Here's an example of one that creates a manifest file for the Safari user agent based on a template file.
// Specify the LinkerOrder as Post... this does not replace the regular GWT linker and runs after it.
#LinkerOrder(LinkerOrder.Order.POST)
public class GwtAppCacheLinker extends AbstractLinker {
public String getDescription() {
return "to create an HTML5 application cache manifest JSP template.";
}
public ArtifactSet link(TreeLogger logger, LinkerContext context, ArtifactSet artifacts) throws UnableToCompleteException {
ArtifactSet newArtifacts = new ArtifactSet(artifacts);
// search through each of the compilation results to find the one for Safari. Then
// generate application cache for that file
for (CompilationResult compilationResult : artifacts.find(CompilationResult.class)) {
// Only emit the safari version
for (SelectionProperty property : context.getProperties()) {
if (property.getName().equals("user.agent")) {
String value = property.tryGetValue();
// we only care about the Safari user agent in this case
if (value != null && value.equals("safari")) {
newArtifacts.add(createCache(logger, context, compilationResult));
break;
}
}
}
}
return newArtifacts;
}
private SyntheticArtifact createCache(TreeLogger logger, LinkerContext context, CompilationResult result)
throws UnableToCompleteException {
try {
logger.log(TreeLogger.Type.INFO, "Using the Safari user agent for the manifest file.");
// load a template JSP file into a string. This contains all of the files that we want in our cache
// manifest and a placeholder for the GWT javascript file, which will replace with the actual file next
String manifest = IOUtils.toString(getClass().getResourceAsStream("cache.template.manifest"));
// replace the placeholder with the real file name
manifest = manifest.replace("$SAFARI_HTML_FILE_CHECKSUM$", result.getStrongName());
// return the Artifact named as the file we want to call it
return emitString(logger, manifest, "cache.manifest.");
} catch (IOException e) {
logger.log(TreeLogger.ERROR, "Couldn't read cache manifest template.", e);
throw new UnableToCompleteException();
}
}
}
Use the gwt2go library's GWT Application Manifest generator to do precisely that. That was easy. :)
