发帖数: 7142 | 1 虚拟机这个我可是非常熟啊。
可是真正开发用虚拟机还是不爽。
有些地方是完全不能用，例如那个 OSX VM 跑
xcode 的模拟器调蓝牙4 的设备肯定连不上。
IOS 开发还是建议搞个正经的 MacMini.
凡是用到 HID 类的非键盘 USB 设备，例如
很多 ARM 的 JTAG-Debugger 在 VM 里就是
没法用。这个是由于 VM 毕竟要把 IO 搞两次，
一次在 GUEST， 一次在 HOST, 延时上去了很多
比较敏感的设备就歇菜了。这个是硬伤，没法逾越的。
如果没有外设问题的花，很多 VM 还能勉强一下。
对严肃开发来说 VM 一般都是太慢。 |

发帖数: 6 | 3 我在windows下用Visual C++ .net写C++程序.编译通过,但用debugger调试程序,首先在
for loop 里,程序有时执行几行就跳回for,有时又从for直接跳到loop里下面几行.而且
loop counter的值在watch window中一直不变.e.g. for (n=0;n<100;n++) watch window
中n的值
总是loop前的值,但我在loop中cout n 的值又是正确的.
请问是不是我的VC++ .net有问题?
BTW,我用的是从学校Microsoft Software Developer Network - Academic Alliance下载
的
Microsoft Development Environment 2003 Version 7.1.3088 和 Microsoft .NET
Framework Version 1.1.4322 SP1
多谢高人指点? |

发帖数: 49 | 7 很久以前用过一阵insight, 记得只要在insight里打开.exe文件就会显示对应的.c文件。
可现在打开.exe看到的都是不可读的机器码，用最简单的程序（如下）试了也不行。
#include
int main()
{
double x=1.4;
printf("This is a C program\n");
return 0;
}
请问我是忘了哪个步骤吗？
多谢指点。 |

I have an animation gif file assigned to pictureBox:
pbStatus.Image = System.Drawing.Image.FromFile("runningRabbit.gif")
in designer the rabbit is running, but when run from debugger or released
app,
the rabbit is still. What's wrong? |

发帖数: 734 | 9 At the beginning of the quoted code, TPS[0...3] is printed.
In the for-loop, at the end of the printf statement TPS[iCpt]
is printed again where iCpt=1...?. However I can't match up the
output with the code, even after seeing the "correction".
kosine you need to post a clearer explanation of what you see
as wrong. Print the address of the variable and the value of
the variable, or run the code in a debugger, make sure you are
looking at the same thing. |

如果你的VC安装没有问题，你可以调试已经在运行的程序(process)。

发帖数: 149 | 26 来自主题: Programming版 - dll求救 What happens when you single-step into one of your dll
function entry points from your debugger?
If you're seeing only x86 disassembly then probably you
need to figure out how to set your symbol path |

most likely you'll just see a bunch of hex addresses on the callstack

发帖数: 13 | 28 请教这里的C++ guru们,谁能解释一下以下几种C++继承中的基类和继承类在内存中是什
么样的结构:
class A

int fieldA;
int func();
}
class B : class A
{
int fieldB;
int func();

1. inheritance without virtual functions
[This I know] the memory layout is as simple as: [fieldA fieldB]
2. inheritance with virtual functions
[Not quite clear] looks like in debugger memory [vtprA fieldA fieldB]
should there be a vtable pointer for B?
3. multiple inheritance if there is a class C:A and a class D:B, C
4. multiple inheritance with virtual |

发帖数: 149 | 29 Depends on how fluent you are with x86 assembly. You can probably still hook
up a debugger with OS symbols and figure out quite a lot about the

You are given a the source to an application which is crashing when run.
After running it 10 times in a debugger, you find it never crashes in the
same place. The application is single threaded, and uses only the C
standard

发帖数: 4406 | 32 那应该是教得不好。
我倒是觉得IDE对新手还是有用的。
我遇到不少已开始就用命令行写C/C++的，被指针错误弄得抓狂，
最后干脆放弃了。而用VC的debugger,一步步调试，一会就通了，
以后慢慢不犯低级错误了，换成命令行也容易。 |

发帖数: 1453 | 33 那么多讨论debugging的帖子都没有提到windbg的.难道大家在windows上debug都是VS?
windows和gdb相比较的是windbg,超级强大. VS完全是另外一个路子的, 虽然code base
开始是一样的. 当然manage code debugger那一套还是VS方便. windbg超多extension,
一点不比gdb弱. tracing还有基于trace的checker windows也有很多方案, 不比
valgrind差, 不光是memory leak, registry, file, concurrency都可以check. |

发帖数: 1453 | 34 en.可能我没说清楚.windbg就是debugger.valgrind是个emulator.valgrind有个缺点是
纯粹runtime的，不能take a trace然后在trace file上做。我还是两年前用过，不知
道现在怎么样。

我相信windbg走的和valgrind不是同一个路子, 功能也不能相比
valgrind基本上是个模拟器, boundschecker还比较接近
可能因为我做硬件, 对模拟器比较熟-_- |

发帖数: 21 | 36 minidump is mainly used for Post-Mortem debugging. So, if you porgram
crashed at a customer site(no debugger installed), you can get the minidump
file and start VS or windbg to debug it(assuming that you have correct pdb
files).The downside is that you have to add extra code to your program to
generate the dump. I am not sure linux/unix needs that.

发帖数: 20343 | 37 有些警告是不可避免的。 例如，当你在debugger下用C++ STL， 就有警告说最长变量
名是256字符。长于256就会
被砍掉。出现这种警告是因为编译器把STL的变量名展开就会很长很长，除非两个变量
的名被砍掉后碰巧一样，这种警
告一般是完全可以忽略。 |
