  • Form submit to target iframe only works once

    - by Pointy
    I'm having a really irritating problem doing something that I'm sure I've done before. The setup is this: There's a form which is submitted via a "click" handler on a button, though the submit is ultimately a simple call to the form's native submit() function. The form's target is an iframe, which is initially filled with an empty page (that is, its source object is an URL for an empty page). That is, the "target" attribute of the form is the same identifier (and yes, it's a valid identifier) as the "name" and "id" attributes of the iframe (and yes, it's unique) Now the goal of this setup is as follows: the form contains file upload fields. Should something be wrong with one of the files uploaded, the server will report back an error. If the error response (that is, the html page with a new copy of the form, along with appropriate error messages) were to be allowed to reload the original window, then the file input fields would be cleared. That's not good. Thus the form submits to the iframe, so that the response from the server can be a small page that knows it's in that hidden iframe, and knows to move the error messages up to the form. One more thing: the form itself is also in an iframe, as part of a popup modal dialog (like a jQuery UI dialog, only slightly different; same idea though). The setup works fine - on the first submit. In other words, if I supply nice happy files to upload, the server ships back the successful response, and the dialog is closed correctly. If I send a bogus file, the server responds with an error page that correctly copies its stuff up to the form page. On the second submit, however (like, if I fix the bogus file input field), the browser insists on sending the server response to a new browser tab. As far as I can tell, the form's "target" remains correct, the iframe "name" and "id" attributes aren't changed, and I even make sure to update the hidden iframe "window.name" and "window.id" values. None of that is helping; I always get a new browser tab. I'm trying to set up a slightly simpler test case to see if I can rule out some of my framework code (the stuff that does the submit), though via a few console.log() calls I think that stuff is OK; it's certainly OK on all the other dialogs etc. in the site. When/if I create a simpler version I'll post it. In the meantime, if any of you insanely smart people recognize this situation and know of a trick to make it work, I'd be really thankful. I see the same behavior in both Firefox (3.6) and Chrome, so it's got to be my problem and not a browser quirk (well, at least that's what I think to be true).

  • Serialization Error:Unable to generate a temporary class (result=1)

    - by ltech
    Running XSD.exe on my xml to generate C# class. All works well except on this property [System.Xml.Serialization.XmlArrayAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] [System.Xml.Serialization.XmlArrayItemAttribute("ATTRIBUTES", typeof(DOCUMENTDocumentATTRIBUTES), Form=System.Xml.Schema.XmlSchemaForm.Unqualified, IsNullable=false)] public DocumentATTRIBUTES[][] Document { get { return this.documentField; } set { this.documentField = value; } } I want to try and use CollectionBase, and this was my attempt public DocumentATTRIBUTESCollection Document { get { return this.documentField; } set { this.documentField = value; } } /// <remarks/> [System.SerializableAttribute()] [System.Diagnostics.DebuggerStepThroughAttribute()] [System.ComponentModel.DesignerCategoryAttribute("code")] [System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)] public partial class DocumentATTRIBUTES { private string _author; private string _maxVersions; private string _summary; /// <remarks/> [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)] public string author { get { return _author; } set { _author = value; } } /// <remarks/> [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)] public string max_versions { get { return _maxVersions; } set { _maxVersions = value; } } /// <remarks/> [System.Xml.Serialization.XmlElementAttribute(Form = System.Xml.Schema.XmlSchemaForm.Unqualified)] public string summary { get { return _summary; } set { _summary = value; } } } public class DocumentAttributeCollection : System.Collections.CollectionBase { public DocumentAttributeCollection() : base() { } public DocumentATTRIBUTES this[int index] { get { return (DocumentATTRIBUTES)this.InnerList[index]; } } public void Insert(int index, DocumentATTRIBUTES value) { this.InnerList.Insert(index, value); } public int Add(DocumentATTRIBUTES value) { return (this.InnerList.Add(value)); } } However when I try to serialize my object using XmlSerializer serializer = new XmlSerializer(typeof(DocumentMetaData)); I get the error: {"Unable to generate a temporary class (result=1).\r\nerror CS0030: Cannot convert type 'DocumentATTRIBUTES' to 'DocumentAttributeCollection'\r\nerror CS1502: The best overloaded method match for 'DocumentAttributeCollection.Add(DocumentATTRIBUTES)' has some invalid arguments\r\nerror CS1503: Argument '1': cannot convert from 'DocumentAttributeCollection' to 'DocumentATTRIBUTES'\r\n"} the XSD pertaining to this property is <xs:complexType> <xs:sequence> <xs:element name="ATTRIBUTES" minOccurs="0" maxOccurs="unbounded"> <xs:complexType> <xs:sequence> <xs:element name="author" type="xs:string" minOccurs="0" /> <xs:element name="max_versions" type="xs:string" minOccurs="0" /> <xs:element name="summary" type="xs:string" minOccurs="0" /> </xs:sequence> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element>

  • Core Data error when assigning variable with one-to-one relationship

    - by Hoang Pham
    I tried to assign a managed object (C) with its property another managed object (B) (a one-to-one relationship) in which this other managed object (B) has a to-many relationship with one other managed object (A). There is an error from this assignment in which I copied as follows: #0 0x020e53a7 in ___forwarding___ #1 0x020c16c2 in __forwarding_prep_0___ #2 0x02078988 in CFRetain #3 0x0207a728 in CFSetAddValue #4 0x020c2fb2 in CFSetCreate #5 0x01e51ce8 in -[_NSFaultingMutableSet copyWithZone:] #6 0x020afcca in -[NSObject copy] #7 0x01e50d22 in -[NSManagedObject(_NSInternalMethods) _newPropertiesForRetainedTypes:andCopiedTypes:preserveFaults:] #8 0x01e51aa0 in -[NSManagedObject(_NSInternalMethods) _newAllPropertiesWithRelationshipFaultsIntact__] #9 0x01e519b4 in -[NSManagedObjectContext(_NSInternalChangeProcessing) _establishEventSnapshotsForObject:] #10 0x01e51866 in _PFFastMOCObjectWillChange #11 0x01e516c5 in _PF_ManagedObject_WillChangeValueForKeyIndex #12 0x01e51525 in _sharedIMPL_setvfk_core #13 0x01e51483 in _PF_Handler_Public_SetProperty #14 0x01e546d1 in -[NSManagedObject(_NSInternalMethods) _didChangeValue:forRelationship:named:withInverse:] #15 0x0030ec1e in NSKVONotify #16 0x002aae2a in -[NSObject(NSKeyValueObserverNotification) didChangeValueForKey:] #17 0x01e5212f in _PF_ManagedObject_DidChangeValueForKeyIndex #18 0x01e515b1 in _sharedIMPL_setvfk_core #19 0x01e55827 in _svfk_5 I don't understand very well what the exact description of this error is. Can someone explain to me what it is and how to solve this one. Note that all other assignments in which the managed object B does not have any A items do not raise this error. ObjectC *objectC = [NSEntityDescription insertNewObjectForEntityForName:@"ObjectC" inManagedObjectContext:managedObjectContext]; objectC.objectB = objectB; Thank you in advance.

  • Changing the appearance of a custom android checkbox without the image scaling?

    - by Joren
    I have a custom checkbox with these attributes: android:id="@+id/map_toolbar_details" android:layout_width="80px" android:layout_height="106px" android:scaleType="center" macro:selectedResource="@drawable/map_toolbar_details_selected" android:button="@drawable/map_toolbar_details" When I load it up, the image gets stretched, even though it's set to scaleType center. If I set a background, I do not have this problem.

    I've added the AssemblyInfo Task reference to my C# project file (VS2008 .NET 3.5), but when I build I get the following error The "AssemblyInfo" task failed unexpectedly. System.ArgumentException: version Parameter name: The specified string is not a valid version number at Microsoft.Build.Extras.Version.ParseVersion(String version) at Microsoft.Build.Extras.AssemblyInfo.Execute() at Microsoft.Build.BuildEngine.TaskEngine.ExecuteInstantiatedTask(EngineProxy engineProxy, ItemBucket bucket, TaskExecutionMode howToExecuteTask, ITask task, Boolean& taskResult) My assemblyinfo file has these two attributes: [assembly: AssemblyVersion("1.0.0.0")] [assembly: AssemblyFileVersion("1.0.0.0")]

  • Detect file creation date on iPhone OS?

    - by Greg Maletic
    I was planning on writing some code whose logic was based upon testing the creation date of a particular file in my app's Documents folder. Turns out, when I call -[NSFileManager attributesOfItemAtPath:error:], NSFileCreationDate isn't one of the provided attributes. Is there no way to discover a file's creation date? Thanks.

  • Best way to manipulate XML in .NET

    - by Juan Manuel Formoso
    I need to manipulate an existing XML document, and create a new one from it, removing a few nodes and attributes, and perhaps adding new ones, what would be the best group of classes to accomplish this? There are a lot of .NET classes for XML manipulation, and I'm not sure what would be the optimal way to do it.

    I was able to do the following in Rails 2.3.5 to access attributes that I set on the session from within my Rails app. Now in Rails 3, env["rack.session"] is nil. How do I do the same thing in Rails 3? class CallbackFilter def initialize(app) @app = app end def call(env) unless env["rack.session"][:oauth_callback_method].blank? env["REQUEST_METHOD"] = env["rack.session"].delete(:oauth_callback_method).to_s.upcase end @app.call(env) end end

  • SWFObject redirectUrl not functional with ExpressInstall

    - by Stefan Kendall
    How do you specify a redirect URL for the adobe flash express install? I'm using swfobject 2.2, and while I thought MMredirectURL in the flashvars might be what I needed, this just doesn't work. I also tried setting redirectUrl in the attributes object before embedding the swf, but this doesn't work either. What is the proper way to specify a redirect URL to go through after the Express Install occurs with swfobject 2.2?

  • Succinct introduction to C++/CLI for C#/Haskell/F#/JS/C++/... programmer

    - by Henrik
    Hello everybody, I'm trying to write integrations with the operating system and with things like active directory and Ocropus. I know a bunch of programming languages, including those listed in the title. I'm trying to learn exactly how C++/CLI works, but can't find succinct, exact and accurate descriptions online from the searching that I have done. So I ask here. Could you tell me the pitfalls and features of C++/CLI? Assume I know all of C# and start from there. I'm not an expert in C++, so some of my questions' answers might be "just like C++", but could say that I am at C#. I would like to know things like: Converting C++ pointers to CLI pointers, Any differences in passing by value/doubly indirect pointers/CLI pointers from C#/C++ and what is 'recommended'. How do gcnew, __gc, __nogc work with Polymorphism Structs Inner classes Interfaces The "fixed" keyword; does that exist? Compiling DLLs loaded into the kernel with C++/CLI possible? Loaded as device drivers? Invoked by the kernel? What does this mean anyway (i.e. to load something into the kernel exactly; how do I know if it is?)? L"my string" versus "my string"? wchar_t? How many types of chars are there? Are we safe in treating chars as uint32s or what should one treat them as to guarantee language indifference in code? Finalizers (~ClassName() {}) are discouraged in C# because there are no garantuees they will run deterministically, but since in C++ I have to use "delete" or use copy-c'tors as to stack allocate memory, what are the recommendations between C#/C++ interactions? What are the pitfalls when using reflection in C++/CLI? How well does C++/CLI work with the IDisposable pattern and with SafeHandle, SafeHandleZeroOrMinusOneIsInvalid? I've read briefly about asynchronous exceptions when doing DMA-operations, what are these? Are there limitations you impose upon yourself when using C++ with CLI integration rather than just doing plain C++? Attributes in C++ similar to Attributes in C#? Can I use the full meta-programming patterns available in C++ through templates now and still have it compile like ordinary C++? Have you tried writing C++/CLI with boost? What are the optimal ways of interfacing the boost library with C++/CLI; can you give me an example of passing a lambda expression to an iterator/foldr function? What is the preferred way of exception handling? Can C++/CLI catch managed exceptions now? How well does dynamic IL generation work with C++/CLI? Does it run on Mono? Any other things I ought to know about?

  • Reusing XSL template to be invoked with different relative XPaths

    - by meomaxy
    Here is my contrived example that illustrates what I am attempting to accomplish. I have an input XML file that I wish to flatten for further processing. Input file: <BICYCLES> <BICYCLE> <COLOR>BLUE</COLOR> <WHEELS> <WHEEL> <WHEEL_TYPE>FRONT</WHEEL_TYPE> <FLAT>NO</FLAT> <REFLECTORS> <REFLECTOR> <REFLECTOR_NUM>1</REFLECTOR_NUM> <COLOR>RED</COLOR> <SHAPE>SQUARE</SHAPE> </REFLECTOR> <REFLECTOR> <REFLECTOR_NUM>2</REFLECTOR_NUM> <COLOR>WHITE</COLOR> <SHAPE>ROUND</SHAPE> </REFLECTOR> </REFLECTORS> </WHEEL> <WHEEL> <WHEEL_TYPE>REAR</WHEEL_TYPE> <FLAT>NO</FLAT> </WHEEL> </WHEELS> </BICYCLE> </BICYCLES> The input is a list of <BICYCLE> nodes. Each <BICYCLE> has a <COLOR> and optionally has <WHEELS>. <WHEELS> is a list of <WHEEL> nodes, each of which has a few attributes, and optionally has <REFLECTORS>. <REFLECTORS> is a list of <REFLECTOR> nodes, each of which has a few attributes. The goal is to flatten this XML. This is the XSL I'm using: <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions"> <xsl:output method="xml" encoding="UTF-8" indent="yes" omit-xml-declaration="yes" xml:space="preserve"/> <xsl:template match="/"> <BICYCLES> <xsl:apply-templates/> </BICYCLES> </xsl:template> <xsl:template match="BICYCLE"> <xsl:choose> <xsl:when test="WHEELS"> <xsl:apply-templates select="WHEELS"/> </xsl:when> <xsl:otherwise> <BICYCLE> <COLOR><xsl:value-of select="COLOR"/></COLOR> <WHEEL_TYPE/> <FLAT/> <REFLECTOR_NUM/> <COLOR/> <SHAPE/> </BICYCLE> </xsl:otherwise> </xsl:choose> </xsl:template> <xsl:template match="WHEELS"> <xsl:apply-templates select="WHEEL"/> </xsl:template> <xsl:template match="WHEEL"> <xsl:choose> <xsl:when test="REFLECTORS"> <xsl:apply-templates select="REFLECTORS"/> </xsl:when> <xsl:otherwise> <BICYCLE> <COLOR><xsl:value-of select="../../COLOR"/></COLOR> <WHEEL_TYPE><xsl:value-of select="WHEEL_TYPE"/></WHEEL_TYPE> <FLAT><xsl:value-of select="FLAT"/></FLAT> <REFLECTOR_NUM/> <COLOR/> <SHAPE/> </BICYCLE> </xsl:otherwise> </xsl:choose> </xsl:template> <xsl:template match="REFLECTORS"> <xsl:apply-templates select="REFLECTOR"/> </xsl:template> <xsl:template match="REFLECTOR"> <BICYCLE> <COLOR><xsl:value-of select="../../../../COLOR"/></COLOR> <WHEEL_TYPE><xsl:value-of select="../../WHEEL_TYPE"/></WHEEL_TYPE> <FLAT><xsl:value-of select="../../FLAT"/></FLAT> <REFLECTOR_NUM><xsl:value-of select="REFLECTOR_NUM"/></REFLECTOR_NUM> <COLOR><xsl:value-of select="COLOR"/></COLOR> <SHAPE><xsl:value-of select="SHAPE"/></SHAPE> </BICYCLE> </xsl:template> </xsl:stylesheet> The output is: <BICYCLES xmlns:fn="http://www.w3.org/2005/xpath-functions" xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <BICYCLE> <COLOR>BLUE</COLOR> <WHEEL_TYPE>FRONT</WHEEL_TYPE> <FLAT>NO</FLAT> <REFLECTOR_NUM>1</REFLECTOR_NUM> <COLOR>RED</COLOR> <SHAPE>SQUARE</SHAPE> </BICYCLE> <BICYCLE> <COLOR>BLUE</COLOR> <WHEEL_TYPE>FRONT</WHEEL_TYPE> <FLAT>NO</FLAT> <REFLECTOR_NUM>2</REFLECTOR_NUM> <COLOR>WHITE</COLOR> <SHAPE>ROUND</SHAPE> </BICYCLE> <BICYCLE> <COLOR>BLUE</COLOR> <WHEEL_TYPE>REAR</WHEEL_TYPE> <FLAT>NO</FLAT> <REFLECTOR_NUM/> <COLOR/> <SHAPE/> </BICYCLE> </BICYCLES> What I don't like about this is that I'm outputting the color attribute in several forms: <COLOR><xsl:value-of select="../../../../COLOR"/></COLOR> <COLOR><xsl:value-of select="../../COLOR"/></COLOR> <COLOR><xsl:value-of select="COLOR"/></COLOR> <COLOR/> It seems like there ought to be a way to make a named template and invoke it from the various places where it is needed and pass some parameter that represents the path back to the <BICYCLE> node to which it refers. Is there a way to clean this up, say with a named template for bicycle fields, for wheel fields and for reflector fields? In the real world example this is based on, there are many more attributes to a "bicycle" than just color, and I want to make this XSL easy to change to include or exclude fields without having to change the XSL in multiple places.

  • In WPF, What is the best way to create toolbar buttons so that the images are properly scaled?

    - by T.R.
    Specifically, I'm looking to use the 16*16 32-bit png images included with the VS2008ImageLibrary. I've tried manually setting the Height and Width attributes of the image, adjusting margins and padding, adjusting Stretch and RenderOptions. My attempts to create toolbar buttons have all led to either Improper Scaling (blurry icons), the bottom row of pixels on the icon being truncated, or the toolbar button being improperly sized - not to mention the disappearing icons already mentioned Here. Has anyone found the best way to make standard, VisualStudio/WinForms-style toolbar buttons that display properly in WPF?
