Cannot put breakpoint in an ASP.NET MVC view when running in IIS7

I'm forced to use IIS7 because Casini is only x86 and we are running with x64 ELMAH. Something I've noticed since I've switched is that I cannot set breakpoints in ASP.NET MVC views anymore. I'm not totally sure it's because of IIS7, is it? Does it happen to you as well? The Visual Studio (2008) project is configured to use the local I...

Looking for a way to trap CPUID instructions

I am looking for a neat way to trap and fiddle with the CPUID instruction of Linux processes. Played around with ptrace() and patching all cpuid opcodes in all executable mmap'ed regions that are created by a process, replacing them by int3's. Didn't work that well since the CPUID opcode bytes appears quite often as parts of other longer...

gdb, set breakpoint on all functions in a file.

Is there a single command in gdb which can set breakpoints on all the functions in a given file ? I know about rbreak regex which sets breakpoints in matching regular expression functions, but my file doesnt have fixed patterned functions. In another way, is there a command by which I can set a breakpoint on a filename. Which will mean...

how can I put a breakpoint on "something is printed to the terminal" in gdb?

I would like to know from where inside a huge application a certain message is printed. The application is so big and old that it uses all conceivable ways of printing text to the terminal; for example printf(), fprintf(stdout, ...) etc. I write to put a breakpoint on the write() system call but then I'm flooded with too many breakpoint...

How can I trap the unknown cause of a Javascript popup?

I am debugging someone else's web page. There is a link on it which tries to open itself in a popup window, the reason for this is unclear -- there is nothing obvious in the HTML (onclick=foo) to cause this. Disabling JavaScript means the link opens normally. I have Firefox/Firebug/Dom Inspector and would like to trap whatever JavaScrip...

a method with breakpoint is called in WCF service before execution

hi all, I have a strange situation in my application. I have a service that needs to return some value from the DB. My service calls to some method in a singleton (by using the GetInstance method). For the purpose of debugging i wrote logging messages in every method along with a view of the call stack. While debugging i noticed somet...

Python Debugging

I'm not sure if 'debugging' is the right word, but I'm looking for a tool/IDE that would show my which statement/block will be executed next in a particular module. This feature I remember was available in Turbo C++ years back so I assume something similar might be available in some Python IDE? Thanks ...

How do I set a breakpoint inside C# PresentationFramework.dll?

This might be a shot in the dark, but, how would I go about setting a breakpoint inside the following internal static method in PresentationFramework.dll? System.Windows.Documents.TextEditorTyping._ShowCursor() I've run into a very similar situation to Joe, where I am making a custom auto-complete textbox using a TextBox control and a...

Cygwin gdb: Not stopping at breakpoint

I am using cygwin on windows XP. I have a C++ project using makefile. But I am getting a segmentation fault. But gdb is not stopping at breakpoints. I have -g option enabled in makefiles. Gdb shows me the line where the fault is generated. But if I run after inserting breakpoint at any point before the fault line, gdb does not stops. It...

Hi, im using NB 6.8. When i add a breakpoint an icon is added next to the line of code. But that icon is not a pink square but a vertically cutted in half pink square. Is this the new icon that symbolizes the breakpoint (i expected a non-broken pink square) ?? Bye Javi ...

Debugging - Any way to alert if a variable is modified (Break on write)

Most debuggers have a watch function but I find it's kind of useless. I want something like "break on write" so I can tell where my data goes awry. I work in php, python, javascript. A feature like this would be handy in every language. Maybe the watch functions of most modern debuggers have this tucked away somewhere and I'm not awar...

Corruption of the heap & F12 Problem

Hi everyone ! I'm trying to draw a line using GLUT with C++ - the IDE is VS 2008 -but an error message occurred : Windows has triggered a breakpoint in Graphics.exe. This may be due to a corruption of the heap, which indicates a bug in Graphics.exe or any of the DLLs it has loaded. This may also be due to the user ...

Are "EXC_BREAKPOINT (SIGTRAP)" exceptions caused by debugging breakpoints?

I have a multithreaded app that is very stable on all my test machines and seems to be stable for almost every one of my users (based on no complaints of crashes). The app crashes frequently for one user, though, who was kind enough to send crash reports. All the crash reports (~10 consecutive reports) look essentially identical: Date...

C# Breakpoint Weirdness

In my program I've got two data files A and B. The data in A is static and the data in B refers back to the data in A. In order to make sure the data in B is invalidated when A is changed, I keep an identifier for each of the links which is a long byte-string identifying the data. I get this string using BitConverter on some of the impor...

Java Breakpoint being ignored in MyEclipse 8.5 .... Using JRE 1.6.0.20 and Tomcat 5.5.25

I have scoured the web and stackoverflow and didnt find anything specific to 1.6.20 so I am wondering if I am the only one seeing this... I am building a JSP based on SUN JRE 1.6.0.20, Tomcat 5.5.25 and am using MyEclipse 8.5 . After running my Servlet a few times through the code/debug cycle, the IDE just starts ignoring all breakpoint...

Is it able to setup a "data breakpoint" on return value

The scenario is: there is a deep call hierarchy and each call will return HRESULT. If something bad happens, function will return S_FALSE or S_ERROR, and if a call return error, the caller will directly return the error code. normally all function will return S_OK. So when debug an issue, I need to do many trials, see which call returns...

NUnit 2.5.7 requires explicit Debug Attach under VS2010

I've just "upgraded" from NUnit 2.5.2 to NUnit 2.5.7 so that I can run unit tests against an dll's built with .Net Framework 4. I've been using 2.5.2 for a long time via the "StartExternalProgram" property uner project properties. I've never had to explicitly debug attach to the NUnit process in that scenario. Now under 2.5.7 it appear...
