I'm trying to build a game in sfml under windows 10.It shows successful at the time of building.whenever i debug the solution it shows the error message like:
Unhandled exception at 0x00007FFA622C21F9 (sfml-system-2.dll) in picpuz2.exe: 0xC0000005: Access violation reading location 0x0000000000000019.
Under call stack the program stopped at the code:
window.create(sf::VideoMode(300, 300, 32), "PICPUZ");
This is my code:
Please follow the tutorials closely. If you are doing a debug build, you should link with the dlls that end in -d for debug.
For example sfml-system-d-2.dll
Linking release and/or debug to the wrong configuration (release to debug or debug to release) will result in unpredictable crashes.

I'm currently using Qt Creator 4.4.1 with Qt 5.9.2 and the MSVC 2015 32/64 Bit compilers to create a DLL on Windows 7.
In Qt Creator under
Projects -> Build & Run -> Desktop Qt 5.9.2 MSVC2015 xxbit -> Run -> Executable
I've specified the host application, that loads my DLL, so when I hit F5 this app gets executed and loads my DLL without a flaw.
However, on loading, the main app raises an exception which I have no hands-on, making Qt Creator showing up a message box with the following content:
The inferior stopped because it triggered an exception.
Stopped in thread 0 by: Exception at 0x60251637, code 0xc0000005: write access violation at: 0x1, flags=0x0 (first chance).
I now have to close the message box and hit F5 again to proceed.
Because I have to do this for every test run, again and again, it becomes really annoying. So, is there a simplest way to tell CDB from Qt Creator to ignore only that specific type of exception?
Look at the call stack, find the relevant code and see what it does. You should find a try ... catch ... around that line. See whether you can avoid the exception in some way, typically by introducing an if ... else ....
If you cannot avoid it, and you made sure it's really safe to ignore it, start CDB with command line argument -c "sxn c0000005" or the equivalent -c "sxn av", where AV is short for "access violation". You can use sx to see all exception settings.
I encountered the same problem, the problem may be caused by the variable is not initialized, for example:
QLable *lable;
If you forget to allocate memory for this variable, it will cause this error.
lable = new QLable(this);
I think you should check your variables.
I'm using V8 32-bit Version 4.10.253 compiled with Visual Studio 2015.
I'm trying to run the example that Google has at:
Chrome V8 - Getting Started
But when I try to run it, I get:
Exception thrown at 0x00000000 in V8Test.exe: 0xC0000005: Access
violation executing location 0x00000000.
I get this when the following is executed:
Isolate* isolate = Isolate::New(create_params);
My project settings:
To get the project to compile in debug, I set the runtime library to:
Multi-threaded Debug /MTd.
I include the v8 include directory under additional include directories.
Lastly, I include the following libraries:
icuuc.lib icui18n.lib v8_libplatform.lib v8_external_snapshot.lib
v8_base_3.lib v8_base_2.lib v8_base_1.lib v8_base_0.lib v8_libbase.lib
winmm.lib
Anyone know what I'm doing wrong? Thanks in advance.
Ok, I feel stupid. I didn't finish reading the rest of the tutorial. You must copy all the .bin files where your executable is stored. Specifically:
natives_blob.bin
snapshot_blob.bin
V8 will crash at Isolate::New if you do not.
I currently developped a project with VS and OpenCV on my x64 computer and i've a problem with this line:
model->train(image, labels);
image and labels are not empty but i've got this error:
Unhandled exception at at 0x774FC42D in facerec_video.exe: Microsoft C++ exception: cv::Exception at memory location 0x0015EF38.
If i click "continue", program continue and works.
Furthermore, if i set a breakpoint on this line and do a step by step, error message doesn't appear and program works too.
How to resolve this problem ?
Thanks
A comment more than a question:
The following describes an issue I had this evening and what I did to "correct" it. These events required a few hours of time to resolve. As this site is one of my favorite sources of information, thought this post might benefit someone else. Any constructive comments on diagnosing QT Creator run-time exceptions would be welcome. The exception seems to have been the result of corruption in the symbol file for QCored.
Exception (QtCreator debugger KernelBase Exception)
Exception at 0x759fc41f, code: 0x406d1388: Startup complete, flags-0x0 (first chance) in KernelBase!RaiseException
Windows: QtCreator 3.0:
Configuration Build: build-QMRC-Qt_5_2_0_msvc2010_opengl-Debug
Application Output Window displayed exception with a valid build.
Corrective Action:
Deleted Windows subdirectories:
c:\users\\appdata\local\temp\
Run qmake
rebuild debug mode
Using Visual Studio 2010, OpenCV 2.2.2, Windows 7 64x
My code builds successfully then when it goes into debug I get the following error:
First-chance exception at 0x75f0c41f in MachineVisionHW0.exe: Microsoft C++ exception: cv::Exception at memory location 0x002dec90..
Unhandled exception at 0x75f0c41f in MachineVisionHW0.exe: Microsoft C++ exception: cv::Exception at memory location 0x002dec90..
Then I end debug, go to the file directory and run the built executable and it runs fine. Does anybody know how to fix this? It isn't keeping me from building my code, but it is incredibly inconvenient. I will include an example of the code that is doing this below.
int main(){
cv::Mat image1 = cv::imread("img1.JPG", CV_LOAD_IMAGE_GRAYSCALE);
cv::namedWindow("Sample1");
cv::imshow("Sample1", image1);
cv::waitKey(0);
return 1;
}
Do you get the unhandled exception before main?
If not, then your code is somehow doing something to raise the exception. Put a breakpoint on the first line, then hit F5, then once at the breakpoint, step through the code one line at a time to see which one causes the exception, F10 key to do this.
My gut feeling is that when running from the debugger, the cv::imread is failing since it is not finding the img1.jpg from the expected location, the current working directory is that of the solution file, not of the debug output build dir. You can do a quick test and copy the img1.jpg to the dir containing the sln file and see if that fixes the problem.
