Visual Studio断点宏来修改一个值?

2022-01-11 00:00:00 visual-studio debugging macros visual-studio-2008 c++

我正在调试一个应用程序 (C++)，并且我在代码中找到了一个我想要更改值的点(通过调试器).所以现在，我已经设置了一个断点，我这样做了:

I'm debugging an application (C++), and I've found a point in the code where I want to change a value (via the debugger). So right now, I've got a breakpoint set, whereupon I do:

  • 调试器到达断点
  • 我修改了我想改变的变量
  • 我按 F5 继续跑步
  • 起泡、冲洗、重复

它经常碰到这个断点，所以我想自动化它.我想设置断点来运行宏，然后继续执行.

It's hitting this breakpoint a lot, so I would like to automate this. I would like to set the Breakpoint to run a macro, and continue execution.

但是，我没有编写 VisualStudio 宏的经验，所以我不知道修改执行程序变量的命令.我环顾四周，但到目前为止还没有在网上找到任何有用的东西.

However, I have no experience writing VisualStudio macros, so I don't know the commands for modifying a variable of the executing program. I've looked around, but haven't found anything helpful online so far.

推荐答案

我找到了如何使用宏来做到这一点.最初，我尝试使用 Ctrl-Shift-R 录制击键宏，但是当我执行 Ctrl-Alt-Q 时它停止录制.但我能够编辑宏以使其工作.所以这就是我所做的，以防其他人想做类似的事情.

I found how to do this with a macro. Initially, I tried using Ctrl-Shift-R to record a macro of keystrokes, but it stopped recording when I did Ctrl-Alt-Q. But I was able to edit the macro to get it to work. So here's what I did, in case anyone else wants to do something similar.

  • 工具 -> 宏 -> 宏浏览器

  • 右键->新建宏

  • Tools -> Macros -> Macro Explorer

  • Right Click -> New macro

Public Module RecordingModule
    Sub setvalue()
        DTE.Debugger.ExecuteStatement("variable_name=0")
    End Sub
End Module

此宏将执行赋值语句，设置我的变量(在本例中，将其设为 NULL 指针).

This macro will execute the assignment statement, setting my variable (in this case, making it a NULL pointer).

  • 右键单击断点 -> 击中时...
  • 选中运行宏"
  • 选择Macros.MyMacros.RecordingModule.setvalue
  • 勾选继续执行"
  • 点击确定

然后，我能够运行我的程序，自动调整指向 NULL 的指针.这对于测试非常有用，并且不需要重新编译.

Then, I was able to run my program, automatically adjusting a pointer to NULL as it went. This was very useful for testing, and did not require recompiling.
