  • How to prepare KML file for Android Emulator Control?

    - by AndroiDBeginner
    I am trying to test my application with location information. You know the Emulator Control has an ability to load from KML file. (Eclipse - DDMS - Emulator Control - Location Controls - KML - Load KML...) I've prepared KML file using Google earth application with its "Add path". Then saved it by .kml extension and load it on the Eclipse. Eclipse didn't load this KML file. How to prepare KML file for Android Emulator Control?

  • APC not working as expected?

    - by Alix Axel
    I've the following function: function Cache($key, $value = null, $ttl = 60) { if (isset($value) === true) { apc_store($key, $value, intval($ttl)); } return apc_fetch($key); } And I'm testing it using the following code: Cache('ktime', time(), 3); // Store sleep(1); var_dump(Cache('ktime') . '-' . time()); echo '<hr />'; // Should Fetch sleep(5); var_dump(Cache('ktime') . '-' . time()); echo '<hr />'; // Should NOT Fetch sleep(1); var_dump(Cache('ktime') . '-' . time()); echo '<hr />'; // Should NOT Fetch sleep(1); var_dump(Cache('ktime') . '-' . time()); echo '<hr />'; // Should NOT Fetch And this is the output: string(21) "1273966771-1273966772" string(21) "1273966771-1273966777" string(21) "1273966771-1273966778" string(21) "1273966771-1273966779" Shouldn't it look like this: string(21) "1273966771-1273966772" string(21) "-1273966777" string(21) "-1273966778" string(21) "-1273966779" I don't understand, can anyone help me figure out this strange behavior?

  • What to implement today to help yourself fixing bugs in the future?

    - by Heinrich Ulbricht
    Assume you are in the process of developing some really cool software. It will be deployed to a lot of customers. They will need this software and they will use it in time-critical situations. So if something goes wrong they will call (you). And you or your team will be the ones who have to resolve the issue. Fast. You know out of experience this will happen. Now if you could decide what to implement to aid your future self - what would that be?

  • How to debug/break in codedom compiled code

    - by Jason Coyne
    I have an application which loads up c# source files dynamically and runs them as plugins. When I am running the main application in debug mode, is it possible to debug into the dynamic assembly? Obviously setting breakpoints is problematic, since the source is not part of the original project, but should I be able to step into, or break on exceptions for the code? Is there a way to get codedom to generate PDBs for this or something? Here is the code I am using for dynamic compliation. CSharpCodeProvider codeProvider = new CSharpCodeProvider(new Dictionary<string, string>() { { "CompilerVersion", "v3.5" } }); //codeProvider. ICodeCompiler icc = codeProvider.CreateCompiler(); CompilerParameters parameters = new CompilerParameters(); parameters.GenerateExecutable = false; parameters.GenerateInMemory = true; parameters.CompilerOptions = string.Format("/lib:\"{0}\"", Application.StartupPath); parameters.ReferencedAssemblies.Add("System.dll"); parameters.ReferencedAssemblies.Add("System.Core.dll"); CompilerResults results = icc.CompileAssemblyFromSource(parameters, Source); DLL.CreateInstance(t.FullName, false, BindingFlags.Default, null, new object[] { engine }, null, null);

  • Do minidump files contain the timestamp of the crash?

    - by Roger Lipscombe
    The MiscInfoStream in a minidump file contains the process create time. I'd like to find out how long the process has been running for before the crash. Does a minidump file contain the exception timestamp anywhere? WinDbg on this dump file displays the following, which implies that it's in there somewhere... Debug session time: Tue Dec 29 15:49:20.000 2009 (GMT+0) System Uptime: not available Process Uptime: 0 days 0:33:03.000 Note that today's Mar 15, so this is almost certainly the timestamp of the crash. I'd like a programmatic way to retrieve that value and the "Process Uptime" value. I found the MINIDUMP_MISC_INFO_3 structure, which contains some timezone information, but it doesn't seem to contain the exception time.

  • Best Way to Include Debug Code?

    - by stormin986
    I am programming Android applications, and the best way here may or may not be the same as Java in general. I simply want to be able to set a debug flag that will only execute certain portions of code when it's set to true––equiv to C++ setting a preprocessor #define DEBUG and using #ifdef DEBUG. Is there an accepted or best way to accomplish this in Java? Right now I'm just going to set a variable in my Application object, but I don't imagine this is the best way.

  • IE8 is subtracting wrong in JavaScript / jQuery?

    - by Oscar Godson
    In every browser, Win/Mac, Chrome, Safari, Firefox, Opera, IE6, and IE7 they ALL get the following console output: 352 254 But in IE8 I get: 414 434 454 474 Here is my JS/jQuery code: $('#top-breadcrumbs').children('a').each(function(i){ if(!$(this).hasClass('permanent')){ if(permItemWidth+rmItemWidth > $('#top-breadcrumbs').width()){ $(this).addClass('removed'); rmItemWidth = rmItemWidth-$(this).width()+20; } } }); The log code i have above is writing the NEW rmItemWidth value after its been reset in that 2nd if

  • Using trace and dbg in Erlang

    - by Gordon Guthrie
    I am trying to start using erlang:trace/3 and the dbg module to trace the behaviour of a live production system without taking the server down. The documentation is opaque (to put it mildly) and there don't appear to be any useful tutorials online. What I spent all day trying to do was capture what was happening in a particular function by trying to apply a trace to module:function using dbg:c and dbg:p but with no success at all... Does anyone have a succinct explanation of how to use trace in a live Erlang system?

  • How to use Firebug's debugger functions?

    - by TK
    I don't have an experience with any debugger in any language, but I recently found some videos showing Firebug. I'm now playing with Firebug with a script I included an error with. What I understand now is: I can set a breakpoint, which is shown as a red circle. Firebug stops at the breakpoint and gives me 4 options (Continue, Step Into, Step Over and Step Out). What I don't understand are: What is the difference between the 4 options (i.e., Continue, Step Into, Step Over and Step Out)? To me, Step Over is sometimes similar to Step Into... I could be wrong here. I would be grateful if you could explain the differences of the 4 options.

  • Can I configure NUnit so that Debug.Fail doesn't show a message box when I run my tests?

    - by panamack
    I have this property: public SubjectStatus Status { get { return status; } set { if (Enum.IsDefined(typeof(SubjectStatus), value)) { status = value; } else { Debug.Fail("Error setting Subject.Status", "There is no SubjectStatus enum constant defined for that value."); return; } } } and this unit test [Test] public void StatusProperty_StatusChangedToValueWithoutEnumDefinition_StatusUnchanged() { Subject subject = new TestSubjectImp("1"); // assigned by casting from an int to a defined value subject.Status = (SubjectStatus)2; Assert.AreEqual(SubjectStatus.Completed, subject.Status); // assigned by casting from an int to an undefined value subject.Status = (SubjectStatus)100; // no change to previous value Assert.AreEqual(SubjectStatus.Completed, subject.Status); } Is there a way I can prevent Debug.Fail displaying a message box when I run my tests, but allow it to show me one when I debug my application?

  • Issue with RegConnectRegistry connecting to 64 bit machines

    - by RA
    I'm seeing a weird thing when connecting to the performance registry on 64 bit editions of Windows. The whole program stalls and callstacks becomes unreadable. After a long timeout, the connection attempts aborts and everything goes back to normal. The only solution is to make sure that only one thread at the time queries the remote registry, unless the remote machine is a 32 bit Windows XP, 2003, 2000 , then you can use as many threads as you like. Have anyone a technical explanation why this might be happening ? I've spent 2-3 days searching the web without coming up with anything. Here is a test program, run it first with one thread (connecting to a 64 bit Windows), then remove the comment in tmain and run it with 4 threads. Running it with one thread works as expected, running with 4, returns ERROR_BUSY (dwRet == 170) after stalling for a while. Remember to set a remote machine correctly in RegConnectRegistry before running the program. #define TOTALBYTES 8192 #define BYTEINCREMENT 4096 void PerfmonThread(void *pData) { DWORD BufferSize = TOTALBYTES; DWORD cbData; DWORD dwRet; PPERF_DATA_BLOCK PerfData = (PPERF_DATA_BLOCK) malloc( BufferSize ); cbData = BufferSize; printf("\nRetrieving the data..."); HKEY hKey; DWORD dwAccessRet = RegConnectRegistry(L"REMOTE_MACHINE",HKEY_PERFORMANCE_DATA,&hKey); dwRet = RegQueryValueEx( hKey,L"global",NULL,NULL,(LPBYTE) PerfData, &cbData ); while( dwRet == ERROR_MORE_DATA ) { // Get a buffer that is big enough. BufferSize += BYTEINCREMENT; PerfData = (PPERF_DATA_BLOCK) realloc( PerfData, BufferSize ); cbData = BufferSize; printf("."); dwRet = RegQueryValueEx( hKey,L"global",NULL,NULL,(LPBYTE) PerfData,&cbData ); } if( dwRet == ERROR_SUCCESS ) printf("\n\nFinal buffer size is %d\n", BufferSize); else printf("\nRegQueryValueEx failed (%d)\n", dwRet); RegCloseKey(hKey); } int _tmain(int argc, _TCHAR* argv[]) { _beginthread(PerfmonThread,0,NULL); /* _beginthread(PerfmonThread,0,NULL); _beginthread(PerfmonThread,0,NULL); _beginthread(PerfmonThread,0,NULL); */ while(1) { Sleep(2000); } }

  • Finding the actual runtime call tree of a Java Program

    - by Chathuranga Chandrasekara
    Suppose I have a big program that consists of hundreds of methods in it. And according to the nature of input the program flow is getting changed. Think I want to make a change to the original flow. And it is big hassle to find call hierarchy/ references and understand the flow. Do I have any solution for this within Eclipse? Or a plugin? As an example, I just need a Log of method names that is in order of time. Then I don't need to worry about the methods that are not relevant with my "given input" Update : Using debug mode in eclipse or adding print messages are not feasible. The program is sooooo big. :)

  • How to debug and detect hang issue

    - by igor
    I am testing my application (Windows 7, WinForms, Infragistics controls, C#, .Net 3.5). I have two monitors and my application saves and restores forms' position on the first or second monitors. So I physically switched off second monitor and disabled it at Screen Resolution on the windows display settings form. I need to know it is possible for my application to restore windows positions (for those windows that were saved on the second monitor) to the first one. I switched off second monitor and press Detect to apply hardware changes. Then Windows switched OFF the first monitor for a few seconds to apply new settings. When the first monitor screen came back, my application became unresponsive. My application was launched in debug mode, so I tried to navigate via stack and threads (Visual Studio 2008), paused application, started and did not find any thing that help me to understand why my application is not responsive. Could somebody help my how to detect the source of issue.

  • Fixing a multi-threaded pycurl crash.

    - by Rook
    If I run pycurl in a single thread everything works great. If I run pycurl in 2 threads python will access violate. The first thing I did was report the problem to pycurl, but the project died about 3 years ago so I'm not holding my breath. My (hackish) solution is to build a 2nd version of pycurl called "pycurl_thread" which will only be used by the 2nd thread. I downloaded the pycurl module from sourceforge and I made a total of 4 line changes. But python is still crashing. My guess is that even though this is a module with a different name (import pycurl_thread), its still sharing memory with the original module (import pycurl). How should I solve this problem? Changes in pycurl.c: initpycurl(void) to initpycurl_thread(void) and m = Py_InitModule3("pycurl", curl_methods, module_doc); to m = Py_InitModule3("pycurl_thread", curl_methods, module_doc); Changes in setup.py: PACKAGE = "pycurl" PY_PACKAGE = "curl" to PACKAGE = "pycurl_thread" PY_PACKAGE = "curl_thread" Here is the seg fault i'm getting. This is happening within the C function do_curl_perform(). *** longjmp causes uninitialized stack frame ***: python2.7 terminated ======= Backtrace: ========= /lib/libc.so.6(__fortify_fail+0x37)[0x7f209421b537] /lib/libc.so.6(+0xff4c9)[0x7f209421b4c9] /lib/libc.so.6(__longjmp_chk+0x33)[0x7f209421b433] /usr/lib/libcurl.so.4(+0xe3a5)[0x7f20931da3a5] /lib/libpthread.so.0(+0xfb40)[0x7f209532eb40] /lib/libc.so.6(__poll+0x53)[0x7f20941f6203] /usr/lib/libcurl.so.4(Curl_socket_ready+0x116)[0x7f2093208876] /usr/lib/libcurl.so.4(+0x2faec)[0x7f20931fbaec] /usr/local/lib/python2.7/dist-packages/pycurl.so(+0x892b)[0x7f209342c92b] python2.7(PyEval_EvalFrameEx+0x58a1)[0x4adf81] python2.7(PyEval_EvalCodeEx+0x891)[0x4af7c1] python2.7(PyEval_EvalFrameEx+0x538b)[0x4ada6b] python2.7(PyEval_EvalFrameEx+0x65f9)[0x4aecd9]

  • Measuring device drivers CPU/IO utilization caused by my program

    - by Lior Kogan
    Sometimes code can utilize device drivers up to the point where the system is unresponsive. Lately I've optimized a WIN32/VC++ code which made the system almost unresponsive. The CPU usage, however, was very low. The reason was 1000's of creations and destruction of GDI objects (pens, brushes, etc.). Once I refactored the code to create all objects only once - the system became responsive again. This leads me to the question: Is there a way to measure CPU/IO usage of device drivers (GPU/disk/etc) for a given program / function / line of code?

  • How much information does pdb files contain? (C# / .NET)

    - by Silver Dragon
    Is is wise to redistribute the pdb files along with a commercial application? Occasionally, I'm using the stack trace to get a more detailed error reporting logs from the deployed applications; can this functionality be achieved without relying to those files? Also, how much hints of the original source code does these files contain? Would it be easier to reverse-engineer my application using it?
