• Custom Errors "Could no load type error"

  - by anil

  I am creating ASP.Net MVC application and want to handle errors globally. I have set web.config value as mode=On and defaulRedirect="Error.aspx". I have Error.aspx at two places. One at Views/Shared folder and one at project root folder level. But each time an unhandled error occurs, the error page at root level gets called. How can I make it redirect to the one at Shared folder level? I want to do this becasuse, currently I am getting error as "could not load type System.Web.Mvc.ViewPage" when any error is occuring. Regards, Anil

• Leaving out type="text/javascript" language="javascript"

  - by coffeeaddict

  Most of the script tags I create, I always include type="text/javascript" language="javascript" in the tag. My boss however does not. Sometimes he excludes both, sometimes just has language=javascript even without the quotes Now we have not had an issue in any of the major browsers with his tags. I'm talking about all versions of IE, FF, Safari, and Chrome. Personally I feel it's laziness and just totally improper and bad coding practice to leave stuff out like this even if it works without it. Anyone know if both should be included or just one or is it ok to leave both out in ASP.NET?

• How to CompareTo two Object without known about their real type

  - by Kamil

  I have to implement a one linked list but it should put object in appropriate position. Everything was OK when I use it in conjunction with specific class, but when I tried make it universal and argument of method insert was Object some problem appeared. When I want to input Object in right position I should use CompareTo method, but there isn't method in Object class! The problem is how to compare two object elements without known about their real types. Maybe I should use generic class type? But what about CompareTo? Or maybe combine with Element class and place CompareTo there? I suppose it is feasible. :) public void insert(Object o) { Element el = new Element(o); // initializing and setting iterators while(!it.isDone() && ((it.current().getValue())).CompareTo(o)<0) // it.current() returns Element of List { //move interators } //... }

• Nullable Enum nullable type question

  - by Michael Kniskern

  I get the following compilation error with the following source code: Compilation Error: Type of conditional expression cannot be determined because there is no implicit conversion between '' and 'MyEnum' Source Code public enum MyEnum { Value1, Value2, Value3 } public class MyClass { public MyClass() {} public MyEnum? MyClassEnum { get; set; } } public class Main() { object x = new object(); MyClass mc = new MyClass() { MyClassEnum = Convert.IsDBNull(x) : null ? (MyEnum) Enum.Parse(typeof(MyEnum), x.ToString(), true) }; } How can I resolve this error?

• Generic type parameters using out

  - by Mikael

  Im trying to make a universal parser using generic type parameters, but i can't grasp the concept 100% private bool TryParse<T>(XElement element, string attributeName, out T value) where T : struct { if (element.Attribute(attributeName) != null && !string.IsNullOrEmpty(element.Attribute(attributeName).Value)) { string valueString = element.Attribute(attributeName).Value; if (typeof(T) == typeof(int)) { int valueInt; if (int.TryParse(valueString, out valueInt)) { value = valueInt; return true; } } else if (typeof(T) == typeof(bool)) { bool valueBool; if (bool.TryParse(valueString, out valueBool)) { value = valueBool; return true; } } else { value = valueString; return true; } } return false; } As you might guess, the code doesn't compile, since i can't convert int|bool|string to T (eg. value = valueInt). Thankful for feedback, it might not even be possible to way i'm doing it. Using .NET 3.5

• Size of int in C on different architectures

  - by NawaMan

  I am aware that the specification of the C language does not dictate the exact size of each integer type (e.g., int). What I am wondering is: Is there a way in C (not C++) to define an integer type with a specific size that ensures it will be the same across different architectures? Like: typedef int8 <an integer with 8 bits> typedef int16 <an integer with 16 bits> Or any other way that will allow other parts of the program to be compiled on different architecture.

• Python: convert buffer type of SQLITE column into string

  - by Volatil3

  I am new to Python 2.6. I have been trying to fetch date datetime value which is in yyyy-mm-dd hh:m:ss format back in my Python program. On checking the column type in Python I get the error: 'buffer' object has no attribute 'decode'. I want to use the strptime() function to split the date data and use it but I can't find how to convert a buffer to string. The following is a sample of my code (also available here): conn = sqlite3.connect("mrp.db.db", detect_types=sqlite3.PARSE_DECLTYPES) cursor = conn.cursor() qryT = """ SELECT dateDefinitionTest FROM t WHERE IDproject = 4 AND IDstatus = 5 ORDER BY priority, setDate DESC """ rec = (4,4) cursor.execute(qryT,rec) resultsetTasks = cursor.fetchall() cursor.close() # closing the resultset for item in resultsetTasks: taskDetails = {} _f = item[10].decode("utf-8") The exception I get is: 'buffer' object has no attribute 'decode'

• Dynamic type for List<T>?

  - by Brett

  Hi All, I've got a method that returns a List for a DataSet table public static List<string> GetListFromDataTable(DataSet dataSet, string tableName, string rowName) { int count = dataSet.Tables[tableName].Rows.Count; List<string> values = new List<string>(); // Loop through the table and row and add them into the array for (int i = 0; i < count; i++) { values.Add(dataSet.Tables[tableName].Rows[i][rowName].ToString()); } return values; } Is there a way I can dynamically set the datatype for the list and have this one method cater for all datatypes so I can specify upon calling this method that it should be a List<int or List<string> or List<AnythingILike>? Also, what would the return type be when declaring the method? Thanks in advance, Brett

• Intellij-Idea: Marking all files of unknown type as text (so that they are searchable)

  - by sixtyfootersdude

  Many of my scripts etc in intellij are marked with a question mark. Then when I click on them them it prompts me: The file "bla" cannot be associated with a registered file type. Please choose one: <insert table of file choices> This would not matter except the files are not searchable (with ctrl-shift-n) until they are marked as text. This is a major problem for me. I have an enormous code base and I don't want to mark all of the unknown files as text. Is there anyway that I can do that?

• Tomcat Exception-Type Ignoring Specific Exception for More General

  - by David Marks

  For one type of exception, IOException, I want to display one page. For all other exceptions I have a default error page. In my web.xml I have things setup like this: java.io.IOException /queryException.jsp java.lang.Exception /error.jsp The problem is the error.jsp is the only page that ever shows, even if an IOException is thrown. The order the tags appear in doesn't matter; if I remove the java.lang.Exception tag though, I can get queryException to show for IOExceptions. What is the solution here? How can I keep a general error page for all exceptions EXCEPT for those with specific pages?

• The method split(String) is undefined for the type String

  - by pi

  I am using Pulse - the Plugin Manager for Eclipse and installed. I have the Eclipse 3.5 for mobile development(Pulsar) profile with a couple other profiles. I realized that the split() method called on a string from code such as below: String data = "one, two, three, four"; data.split(","); generates the error: "The method split(String) is undefined for the type String". I am aware that the split() method did not exist before Java's JRE 1.4 and perhaps could be the cause of the problem. The problem is I don't think I have jre/sdk versions installed. Perhaps there's one in-built with the Pulsar profile and needs editing - but I couldn't tell what settings (and where) needs tweaking. I have checked WindowsPreferencesJavaInstalled JREs and it's set to = jre1.4. Please help thanks.

• PHP - Opening uploaded DOCX files with the correct MIME TYPE

  - by user270797

  I have users uploading DOCX files which I make available for download. The issues we have been experiencing is the unknown mime types of DOCX files which causes IE to open these docs as Zip files. It is running on a Windows/IIS server. Because this is a shared host, I cannot change any server settings. I was thinking that I could just write some code that would handle DOCX files, perhaps custom output: if (extension=docx) { header("Content-Disposition: attachment; etc) header('Content-Type: application/application/vnd.openxmlformats-officedocument.wordprocessingml.document'); Output the file contents etc } Would this be a viable solution?? If so, can someone help fill in the gaps? (PS I know the above syntax is not correct, just a quick example)

• How to register a custom type in Hibernate using org.springframework.orm.hibernate4.LocalSessionFactoryBean

  - by Luis

  I'm migrating from hibernate 3 to hibernate 4, In hibernate 3 the way I was registering a custom type was: public class AnnotationSessionFactoryBean extends org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean { private Collection<? extends BasicType> customTypes; public Collection<? extends BasicType> getCustomTypes() { return customTypes; } public void setCustomTypes(Collection<? extends BasicType> customTypes) { this.customTypes = customTypes; } @Override protected Configuration newConfiguration() throws HibernateException { Configuration configuration = super.newConfiguration(); if (CollectionUtils.hasEntries(customTypes)) { for (BasicType customType:customTypes) { configuration.registerTypeOverride(customType); } } return configuration; }} I'm now trying to do the same operation but using hibernate 4, my question is how is the best way to do this? since I dont have access do change configuration when using "org.springframework.orm.hibernate4.LocalSessionFactoryBean" instead of "org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean". Thanks

• An unhandled exception of type 'System.StackOverflowException' occurred in System.Windows.Forms.dll

  - by Tanner

  OK, Im trying to highlight keywords in a richtextbox, the problem is I've got the code to highlight only the visible text on textChanged event,so I tryed putting the code in the richtextbox VScroll, so when I scrolled up it would highlight the text that wasn't visible before, but every time I start to scroll I get this error: "An unhandled exception of type 'System.StackOverflowException' occurred in System.Windows.Forms.dll" Does any one know why? Or maybe a way I could highlight the words while scrolling? Thanks, Tanner. int selectionstart = richTextBox1.Selectionstart; int topIndex = richTextBox1.GetCharIndexFromPosition(new Point(1, 1));//This is where I get the error. int bottomIndex = richTextBox1.GetCharIndexFromPosition(new Point(1, richTextBox1.Height - 1)); int topLine = richTextBox1.GetLineFromCharIndex(topIndex); int bottomLine = richTextBox1.GetLineFromCharIndex(bottomIndex); int start = richTextBox1.GetFirstCharIndexFromLine(topLine); int end = richTextBox1.GetFirstCharIndexFromLine(bottomLine); int numLinesDisplayed = (bottomLine - topLine) + 2; richTextBox1.Focus(); richTextBox1.Select(start, end);

• C# ASP.Net The type or namespace name 'Secure' does not exist in the namespace 'source_extranet'

  - by Louis Russell

  Afternoon all, I really need your help as this is a Nightmare! I was earlier having a problem with referencing a 3rd Party Dll (Here) but have overcome this problem and am now having a problem referencing my own classes! Everything seems fine at build with no errors at all but when I go to run the application it comes up with the following Compilation Error: Compiler Error Message: CS0234: The type or namespace name 'Secure' does not exist in the namespace 'source_extranet' (are you missing an assembly reference?) The line that the Error points to this line in the class: source_extranet.Secure.BackendCustomData newdata = new source_extranet.Secure.BackendCustomData(); This line of code points to a class in the same folder as the calling code class. I have scoured Google looking for an answer and haven't found anything that points me to an answer to my problem. Any help would be AMAZING!

• Casting a non-generic type to a generic one

  - by John Sheehan

  I've got this class: class Foo { public string Name { get; set; } } And this class class Foo<T> : Foo { public T Data { get; set; } } Here's what I want to do: public Foo<T> GetSome() { Foo foo = GetFoo(); Foo<T> foot = (Foo<T>)foo; foot.Data = GetData<T>(); return foot; } What's the easiest way to convert Foo to Foo<T>? I can't cast directly InvalidCastException) and I don't want to copy each property manually (in my actual use case, there's more than one property) if I don't have to. Is a user-defined type conversion the way to go?

• Type casting needed for byte = byte - byte?

  - by Vaccano

  I have the following code: foreach (byte b in bytes) { byte inv = byte.MaxValue - b; // Add the new value to a list.... } When I do this I get the following error: Cannot implicitly convert type 'int' to 'byte'. An explicit conversion exists (are you missing a cast?) Each part of this statement is a byte. Why does C# want to convert the byte.MaxValue - b to an int? Shouldn't you be able to do this some how without casting? (i.e. I don't want to have to do this: byte inv = (byte) (byte.MaxValue - b);)

• Python IDLE: How to type correct indentation?

  Mac: Maverick Python: 3.4 I tried to testtimeit module in Python's IDLE import timeit >>> timeit.timeit( "obj.method", """ class SomeClass: def method(self): pass obj = SomeClass() """) When I tried to type def method(self): on the next line of class SomeClass, I hit Tab, it prompted a window showing the files inside my Document directory.

• File size and mime-type before upload

  - by Marcos Placona

  Hi, I've scavenged on every single topic on this forum to try and find an answer before I posted this. Most people say you should simply use SWFUpload, some others mention Activex, and it keeps going. I know this is do-able, as Google does it with gMail when you try to upload a file that's bigger than 25mb, or executable. My question is, how can I determine the file size and mime-type before the file actually hits my server. I primarily thought it was an impossible task, but Google proves me wrong. Could anyone give me a definitive answer on how to accomplish such task? Thanks

• custom tag 'cannot be resolved to a type'

  - by lotus99t

  I have a custom tag, packaged into a library jar that is included in my web apps war file. I get the following error: An error occurred at line: 66 in the jsp file: /WEB-INF/jsp/portlet/portfolio/operations/operationsInfo.jsp org.apache.jsp.tag.meta.form.WidgetFactory_tag cannot be resolved to a type 63: <c:forEach var="fldCfg" items="${config.page.fields}" > 64: <tr> 65: <td><form:Label fld="${fldCfg}"/></td> 66: <td><form:WidgetFactory fld="${fldCfg}" decodesMap="${decodesMap}" command="${operationsInfoBean}" dateFormat="${preferredDateFormat}"/></td> 67: </tr> 68: </c:forEach> 69: </table> But it doesn't seem to complain about Label which is in the same taglib. I've confirmed that the jar is in the war and that the tag file is in the jar and the that the TLD (in META-INF) expressly defines 'WidgetFactory' Why am I getting this error?

• Python mechanize - two buttons of type 'submit'

  - by directedition

  I have a mechanize script written in python that fills out a web form and is supposed to click on the 'create' button. But there's a problem, the form has two buttons. One for 'add attached file' and one for 'create'. Both are of type 'submit', and the attach button is the first one listed. So when I select the forum and do br.submit(), it clicks on the 'attach' button instead of 'create'. Extensive Googling has yielded nothing useful for selecting a specific button in a form. Does anyone know of any methods for skipping over the first 'submit' button and clicking the second?

• Creating Mock object of Interface with type-hint in method fails on PHPUnit

  - by Mark

  I created the following interface: <?php interface Action { public function execute(\requests\Request $request, array $params); } Then I try to make a Mock object of this interface with PHPUnit 3.4, but I get the following error: Fatal error: Declaration of Mock_Action_b389c0b1::execute() must be compatible with that of Action::execute() in D:\Xampp\xampp\php\PEAR\PHPUnit\Framework\TestCase.php(1121) : eval()'d code on line 2 I looked through the stack trace I got from PHPUnit and found that it creates a Mock object that implements the interface Action, but creates the execute method in the following way: <?php public function execute($request, array $params) As you can see, PHPUnit takes over the array type-hint, but forgets about \requests\Request. Which obviously leads to an error. Does anyone knows a workaround for this error? I also tried it without namespaces, but I still get the same error.

• How to make Databinding type safe and support refactoring

  - by Ian Ringrose

  When I wish to bind a control to a property of my object, I have to provide the name of the property as a string. This is not very good because: If the property is removed or renamed, I don’t get a compiler warning. If a rename the property with a refactoring tool, it is likely the data binding will not be updated. I don’t get an error until runtime if the type of the property is wrong, e.g. binding an integer to a date chooser. Is there a design-paten that gets round this, but still has the ease of use of data-binding? (This is a problem in WinForm, Asp.net and WPF and most likely lots of other systems) I have now found "workarounds for nameof() operator in C#: typesafe databinding" that also has a good starting point for a solution.
