Eclipse PDT - how to debug the $_SESSION, $_GET, $_POST variables...
- by waitinforatrain
Hi, I'm stepping through code using Eclipse PDT. When I mouseover an array it says e.g. "$_SESSION = Array [0]", but won't show me the data. This is fine for local varaibles as I can see them in the "Variables" window, but it means that I can't see the contents of $_GET, $_POST, $_SESSION. How do I fix this?Read the article

Dubugging a program not run within the debugger and without a crash
- by Mick
I left a program running last night, it worked fine for about 5 hours and then one of its built-in self-diagnostic tests detected a problem and brought up a dialog box telling me the issue. The program was built with debug information (/Zi). Is it possible to somehow get the debugger started so I can examine the value of some variables within the…Read the article

How to tell which thread(s) are producing all the garbage?
- by Brad Hein
I have an app with about 15 threads. Most do mundane tasks and sleep most of their lives. Others collect information and cache it in hashmaps. The hashmaps grow to a moderate size and level out. The number of keys and size of value remains constant, but the contents of the values changes (at 33 keys per second average). When I start my app, I…Read the article

Breakpoint when variable takes on a certain value.
- by Mick
I have something analogous to the following code... void function(int x) { // complicated operation on x blah blah } It all appears to be working fine except when x happens to be a particular value, say "273". But x being 273 is a rare event, 99.999% of the time it is some other value. Now I wish to observe the events when this…Read the article

Is there a cap on the number of modules WinDbg can see?
- by Bethor
Does anyone know if there is a cap on the number of DLLs WinDbg can see ? I believe Visual Studio was once capped at 500 but I can't find a source for this claim outside of some second hand accounts at work. I'm trying to debug a hairy scenario and WinDbg's stack trace is incomplete. According to Process Explorer, the module I'm interested…Read the article

Using same Debug settings for Start External Program across 32 bit and 64 bit debug environments
- by Michael Prewecki
We use a mixture of 32-bit and 64-bit development environments. Some of our class libraries are debugged using a 32-bit application so we have debug settings for "Start External Program" and "Working Directory". The problem is that the settings need to be different since the 32-bit application is installed to C:\Program Files\xxx (on the…Read the article

I know about DIA api, dbghelp. But can i use them to extract type definition location info such as file, begin_line, begin_column, end_line, end_column from my assembly and pdb generated? If the answer is yes, can someone point me to the simple example out there?Read the article

Call a Firebug command from client code.
- by ProfK
I would like to apply some sort of IoC, with debugee code, i.e. the current HTML document, and the debugger, Firebug. It would be great to have some sort of document that asks Firebug to open a push channel from the document, versus the more common scenario of the debugger pulling information from the debugee document. Is this possible…Read the article

How to interpret kernel panics?

Hi all, I'm new to linux kernel and could barely understand how to debug kernel panics. I have this error below and I don't know where in the C code should I start checking. I was thinking maybe I could echo what functions are being called so I could check where in the code is this null pointer dereferenced. What print function should…Read the article

How can I tell Visual Studio to NOT BREAK on a particular exception?
- by Noel Kennedy
I have a particular type of exception that I would like Visual Studio to not catch with the Exception Assistant. Essentially I would like it just to let my normal exception handling infrastructure deal with it. The exception is an inheritor of System.Exception which I wrote and have the source code for. Any where this is thrown I…Read the article

How do I find where an exception was thrown in C++?
- by Alex
I have a program that throws an uncaught exception somewhere. All I get is a report of an exception being thrown, and no information as to where it was thrown. It seems illogical for a program compiled to contain debug symbols not to notify me of where in my code an exception was generated. Is there any way to tell where my…Read the article

Hello everybody, Are there any programs that render websites from the point of view of different browsers? In other words, I'd like to be able to open and view websites as if it were Internet Explorer, Firefox, Chrome, Safari, etc. It would be a bonus if the utility has a paned interface that lets you view pages side by…Read the article

Recognizing synchronization object hanging two 3rd party executables
- by eran
I'm using a 3rd party tool, which uses a 4th party plugin. Occasionally, the tool will hang when launched. Looking at the stack traces, I can see a few threads are waiting on WaitForSingleObject, and my bet is that they're blocking each other. Some of the threads start at the 3rt party tool, and some at the 4th party…Read the article

How can I debug a win32 process that unexpectedly terminates silently?

I have a Windows application written in C++ that occasionally evaporates. I use the word evaporate because there is nothing left behind: no "we're sorry" message from Windows, no crash dump from the Dr. Watson facility... On the one occasion the crash occurred under the debugger, the debugger did not break---it…Read the article

OutputDebugString + DebugView = not tabs!
