Hello I am doing Direct2D and Win32 programming in Visual Studio. When I debug my application, i get this exception in line 2928 of d2d1.h: Unhandled exception thrown: read access violation. this was nullptr. If anyone can help, that would be…
这是NTSTATUS状态码STATUS_ACCESS_VIOLATION（0xC0000005）对应的消息。消息原文是 The instruction at 0x%...
A Read or Write Access Violation occurs when the application attempts to read or write memory from a memory address that is invalid. To be valid, the memory page must have a valid state, protection and type.The memory must be in the MEM_COMMIT state.The
``` #includetypedef struct AA { unsigned char a; unsigned char b; }SAA; int main(int argc, char *argv[]) { SAA var; char s[]="10"; var.a=1; var.b=2; sscanf_s(s,"%hhu",(unsigned char*)&var.a,sizeof(var.a));//在给var.a赋值时,影响了var.b printf("%hhu %hhu",var....
Running the following code in Debug x86 configuration with vs2019, Version 16.11.22 results in read access violation when the language standard is set to ISO C++20 Standard (/std:c++20). #include <array> #include <vector> std::array<std::vector<int, std::allocator<int>>, 1...
1出现access violation at address2我们需要先右击我的电脑，单击，属性3在“系统属性”中单击，高级4在“性能”中单击，设置5在“性能选项”中单击，数据执行保护6单击“添加”选择要运行的。原理1你如果用翻译软件翻译的话“accessviolationataddress”的意思是“在地址访问冲突”，虽然具体意思不是这样，...
很有可能数据访问互斥没有做好。一般这类interrupt()函数要求都很短小精悍，不能指靠其做很多事情。如果你的主程序能够处理socket消息，可以让interrupt（）给自己发一个触发消息（或者类似的其它机制），然后在主程序处理这条消息时再具体处理你 interrupt()里面那么多的语句。
起始地址错误，看一下是否包括头文件和有写main()函数。
} return -1;你这最后一个return 怎么在括号外面
检查一下你的程序是不是用到了EA=1 如果是把它注释掉 在仿真试试
