  - by voipsecuritydigest.com

  My project contains 2 source folder, one is generic J2EE application another is smartCleintGWT, I want to use some already existing DTO classes from first source folder (src) Note that class used on client side and on server side of GWT project! When I do that I getting error [ERROR] Errors in 'file:/C:/..Projects/Admin/DMX/src_console/com/ho/nod/client/AdminRPC.java' [ERROR] Line 7: No source code is available for type com.dmx.synch.server.descriptors.DMXLicense; did you forget to inherit a required module?

• Unable to reverse seemingly simple rails migration - getting "altered_table.column may not be NULL"

  - by brad

  I have a table 'invoices' in my development database (sqlite3) populated with a small amount of test data. I wanted to add a column 'invoice_number' to it and set up a migration like so: class AddInvoiceNumberColumnToInvoices < ActiveRecord::Migration def self.up add_column :invoices, :invoice_number, :integer end def self.down remove_column :invoices, :invoice_number end end I ran rake db:migrate and it seemed to migrate just fine. However, when I tried to access this column through ActiveRecord it didn't seem to be there. I decided to undo this migration and try again (not sure what I was going to try but I thought I'd start by undoing it) with rake db:migrate VERSION='whatever_the_migration_before_this_one_was_called'. This failed with the error message == AddInvoiceNumberColumnToInvoices: reverting =============================== -- remove_column(:invoices, :invoice_number) rake aborted! An error has occurred, this and all later migrations canceled: altered_invoices.invoice_number may not be NULL I can't find any documentation of this error. Is anyone able to explain what I have done wrong, and more importantly how I can fix this?

• How do I display exception errors thrown by Zend framework

  - by Ali

  Hi guys I'm working with Zend framework and just hate the fact that I seem to encounter hundreds of exception errors like if I try to reference a non existant property of an object my application just dies and crashes. However I have no idea where to see these errors or how to be able to display them on screen. I've set display errors to true and error reporting to E_ALL but when an error is thrown all I see is a blank page rendered only until a bit before where the error apparently occurred or the exception was thrown. Help please my debugging hours are dragging

• Python os.path.join

  - by Jim

  Hello, I am trying to learn python and am making a program that will output a script. I want to use os.path.join but am pretty confused (I know I am very bad at scripting/programming) See, according to the docs ( http://docs.python.org/library/os.path.html ) if I say os.path.join('c:', 'sourcedir') I get C:sourcedir as it's output. According to the docs, this is normal (right?) But when I use the copytree command, Python will output it the desired way, for example import shutil src = os.path.join('c:', 'src') dst = os.path.join('c':', 'dst') shutil.copytree(src, dst) Here is the error code I get WindowsError: [Error 3] The system cannot find the path specified: 'C:src/.' If I wrap the os.path.join with os.path.normpath I get the same error If this os.path.join can't be used this way, then I am confused as to its purpose According to the pages suggested by Stack Overflow, slashes should not be used in join--that is correct I assume? Thanks guys(girls) for your help

• Why isn't an exception thrown when the right .NET framework version is not present?

  - by Nate Heinrich

  We have a .NET application which targets .NET 3.5. Our clients run it from a shared drive (very infrequently) in order to have a central config file location. We have noticed that if a workstation accesses the shared drive and runs the program, but does not have .NET 3.5 installed, nothing happens, no error, no exception, no log entry, it just doesn't launch. Why is there no error message shown in windows by the CLR? Is there something I can put at the beginning of the code that would ensure that a proper error message is displayed? It is not an option to run an installer that would check for prereqs, as we are only installing it in one central location. Thanks.

• Initiate a PHP class where class name is a variable

  - by ed209

  I need some help with an error I have not encountered before and can't seem to find anywhere. In a PHP mvc framework (just from a tutorial) I have the following: // Initiate the class $className = 'Controller_' . ucfirst($controller); if (class_exists($className)) { $controller = new $className($this->registry); } $className is showing the correct class name (case is also correct). But when I run it I get this in the apache error log (no php error) [Wed Mar 31 10:34:12 2010] [notice] child pid 987 exit signal Segmentation fault (11) Process id is different on every call. I am running PHP 5.3.0 on os x 10.6. This site seems to work on 5.2.11 on another Mac. Not really sure where to go next to debug it. I guess it could be an apache setting as much as a php bug or a problem with the code... any suggestions on where to look next?

• What is the most efficient way to find missing semicolons in VS with C++?

  - by Dr. Monkey

  What are the best strategies for finding that missing semicolon that's causing the error? Are there automated tools that might help. I'm currently using Visual Studio 2008, but general strategies for any environment would be interesting and more broadly useful. Background: Presently I have a particularly elusive missing semicolon (or brace) in a C++ program that is causing a C2143 error. My header file dependencies are fairly straightforward, but still I can't seem to find the problem. Rather than post my code and play Where's Wally (or Waldo, depending on where you're from) I thought it would be more useful to get some good strategies that can be applied in this and similar situations. As a side-question: the C2143 error is showing up in the first line of the first method declaration (i.e. the method's return type) in a .cpp file that includes only its associated .h file. Would anything other than semicolons or braces lead to this behaviour?

• Foo f = Foo(); // no matching function for call to 'Foo::Foo(Foo)' ... huh?!

  - by Kyle

  class Foo { public: explicit Foo() {} explicit Foo(Foo&) {} }; Foo d = Foo(); error: no matching function for call to 'Foo::Foo(Foo)' I tried changing Foo(Foo&) to Foo(Foo) as the error suggests, which AFAIK is not a valid constructor, and sure enough I get: error: invalid constructor; you probably meant ‘Foo (const Foo&)’ What gives? How do I resolve this? (This is on GCC by the way)

• Issue with Visual C++ 2010 (Express) External Tools command

  - by espais

  I posted this on SuperUser...but I was hoping the pros here at SO might have a good idea about how to fix this as well.... Normally we develop in VS 2005 Pro, but I wanted to give VS 2010 a spin. We have custom build tools based off of GNU make tools that are called when creating an executable. This is the error that I see whenever I call my external tool: ...\gnu\make.exe): * couldn't commit memory for cygwin heap, Win32 error 487 The caveat is that it still works perfectly fine in VS2005, as well as being called straight from the command line. Also, my external tool is setup exactly the same as in VS 2005. Is there some setting somewhere that could cause this error to be thrown?

• pointer being freed was not allocated

  - by kudorgyozo

  Hello i have the following error: malloc: * error for object 0x2087000: pointer being freed was not allocated * set a breakpoint in malloc_error_break to debug I have no idea what object that is. I don't know how to find it. Can anybody explain to me how (and where) to use malloc_history. I have set a breakpoint in malloc_error_break but i couldn't find out what object is at that address. I receive this after removing an object from an nsmutablearray and popping a view controller manually. If I comment out the line [reviewUpload.images removeObject: self.reviewUploadImg] it doesn't give me the error but of course it's not useful for me like that. - (void) removeImage { debugLog(@"reviewUploadImg %@", self.reviewUploadImg); debugLog(@"reviewUpload %@", self.reviewUpload); debugLog(@"reviewUploadImg thumb %@", self.reviewUploadImg.thumb); [reviewUpload.images removeObject: self.reviewUploadImg]; [self.navigationController popViewControllerAnimated:TRUE]; }

• "Invalid Procedure Call or Argument", but only in a compiled or P-Code EXE

  - by Rob Perkins

  I have a VB6 program which I've been maintaining for ten years. There is a subroutine in the program called "Prepare Copy", which looks like this: Public Sub PrepareCopy() Set CopiedShapes = New Collection End Sub Where CopiedShapes is dimmed out as a VB6 Collection. That code is now kicking out a Runtime Error 5 -- Invalid Procedure Call or Argument. It appears from the interstitial debugging code that the error arises between the Public Sub PrepareCopy() and the Set CopiedShapes = New Collection lines. That's right. The VB6 error is happening between two lines of my code. I can think of no other explanation for this. It's behaving this way on my development machine and two client computers. It is only happening in runtime code, and does not appear to make a difference whether I compile it or use P-Code What I'm asking for here is speculation as to what causes this sort of thing to happen.

• Problem With Inserts of multibyte (converted to utf-8) strings in the mysql tables of utf_unicode_ci encoding

  - by user381595

  http://domainsoutlook.com/sandbox/keyword/?s=http://bhaskar.com raw example of my keyword density analyser. Every keyword shows up properly with no problems in unicode conversions etc. Now, When I am adding these words to the database column of a table, the words show up as messed up. http domainsoutlook.com/b/site/bhaskar.com.html For example on this front end page if you see there is a keyword that is shown as a blank but still occurs on the website 8 times. (It isnt empty in the database though). I have checked and there is no problem with mysql_real_escape_String...because the output stays the same before and after the word is gone through mysql_real_escape_String. Another problem was that I wanted to fix my urls for arabic language. They should be showing up as /word-{1st letter of the word}/{whole word}.html but its showing as /word-{whole word}/{1st letter of the word}.html I really need answers for these two questions.

• Python scope problems only when _assigning_ to a variable

  - by wallacoloo

  So I'm having a very strange error right now. I found where it happens, and here's the simplest code that can reproduce it. def parse_ops(str_in): c_type = "operator" def c_dat_check_type(t): print c_type #c_type = t c_dat_check_type("number") >>> parse_ops("12+a*2.5") If you run it as-is, it prints "operator". But if you uncomment that line, it gives an error: Traceback (most recent call last): File "<pyshell#212>", line 1, in <module> parse_ops("12+a*2.5") File "<pyshell#211>", line 7, in parse_ops c_dat_check_type("number") File "<pyshell#211>", line 4, in c_dat_check_type print c_type UnboundLocalError: local variable 'c_type' referenced before assignment Notice the error occurs on the line that worked just fine before. Any ideas what causes this and how I can fix this? I'm using Python 2.6.1.

• Catching "NullPointerExceptions" in JavaScript

  - by Lenni

  I'm writing quite a bit of code in Prototype.js which returns null if a DOM-id wasn't found. $("someId").show(); If someId doesn't exist, a method will be called on null, which halts the entire program, in effect disabling all JS effects after the error. I could just check for null before executing such a statement, but this is getting tiring. I would like to catch an exception but I'm not sure which one its is. MDC lists the following ECMA Script error types: * Error * EvalError * RangeError * ReferenceError * SyntaxError * TypeError * URIError * DOMException * EventException * RangeException Also, do browsers have a unified way of dealing with a method call on null?

Any ideas? thanks.

• Storing HTML in MySQL using Java

  - by mpcabd

  Hello there again, So, I'm working on a project now where I should store webpages inside a database, I'm using crawler4j to crawl and Proxool along with MySQL Java Connector to connect to my database. When I tested the application I got: com.mysql.jdbc.MysqlDataTruncation: Data truncation: Data too long for column 'HTMLData'. The HTMLData column wasTEXT. When I changed the HTMLData column to LONGTEXT the error was gone, but I'm afraid it might get back in the future. Any idea on how to do that perfectly so I don't worry about that error (or any other similar error) in the future? Thanks :)

• Beginner C++ Question

  I have followed the code example here toupper c++ example And implemented it in my own code as follows void CharString::MakeUpper() { char* str[strlen(m_pString)]; int i=0; str[strlen(m_pString)]=m_pString; char* c; while (str[i]) { c=str[i]; putchar (toupper(c)); i++; } } But this gives me the following compiler error CharString.cpp: In member function 'void CharString::MakeUpper()': CharString.cpp:276: error: invalid conversion from 'char*' to 'int' CharString.cpp:276: error: initializing argument 1of 'int toupper(int)' CharString.cpp: In member function 'void CharString::MakeLower()': This is line 276 putchar (toupper(c)); I understand that toupper is looking for int as a parameter and returns an int also, is that the problem? If so how does the example work?

• Store #VALUE! #NUM! #REF! in variable.

  - by Ommit

  So a simple version of what I'm trying to do. Say I know there is an error in cell(1,1), furthermore I know it is either #num!, #ref! or #value!, I want to be able to store the respective error message in a variable, so I can print it to a different sheet. This is what I tried and it clearly failed. Sub FindAndPrintErrors dim Store as string If IsError(Range("A1"))) = True Then Store = Range("A1").value 'it breaks here' end if range("B1") = Store end sub I know I can do this but I wonder if there is a better way. Sub FindAndPrintErrors2 dim Store If IsError(Range("A1"))) = True Then temp = Range("A1").value 'it breaks here' if temp = "error 2029" then store = "#num!" ' and so on' end if range("B1") = Store end sub
