在Visual Studio中，我可以在断点中绘制我的变量吗？ [英] In Visual Studio can i plot my variable in breakpoint ?

问题描述

在Visual Studio中为我的本机C ++程序，我想在调试期间得到一些变量的图。大多数情况下，我通过编辑autoexp.dat来使用对象的文本表示。但是对于一些变量，最好是用一个情节，而不是以文本形式的值。

到目前为止，我已经使用了一个函数 plot （const void * address，const char * type），并从立即窗口中调用它，给出可变地址&该类型，并在内部将其转换为适当的类型。

但是这种方法有两个缺点：

• 首先是，从调试器调用函数时，函数重载几乎从不起作用（所以我不得不将类型作为第二个参数传递），并且函数调用偶尔会崩溃，尽管在代码中调用时它的工作正常。第二，不用编写一个C ++函数来绘制，我有兴趣有一个脚本语言（如autoexp.dat或一个VBScript）给出C ++对象的内部数据没有写任何包装器，所以我可以使用脚本将数据存储在一个文件或绘图。

一般来说，我有兴趣像Matlab 或 Ch IDE 这样的东西，当程序处于调试中断时，我可以在外部绘制某些变量。

解决方案

自VS 2005以来，Visual Studio已经包括可视化器，几乎可以专门为您的问题设计。 MSDN比我可以更好地解释这个概念：

Visualizer是
Visual Studio调试器用户界面的新组件。
可视化器创建一个对话框或
其他接口，以一种有意义的方式显示一个变量
或对象，这是一种适合其数据类型的
。对于
示例，HTML可视化程序将

In Visual Studio for my native C++ program I want to get a plot of some variables during debug. Mostly I use textual representation of the objects by editing autoexp.dat. But for some of the variables it is better to have a plot rather than having values in textual form.

So far I have used a function plot(const void* address,const char* type) , and called it from Immediate Window giving the variable address & the type, and internally casting it to proper type.

But this method has two disadvantages:

• First is that, function overloading almost never works when calling a function from debugger (so I had to pass type as a second parameter), and the function call occasionally crashes, though it works perfectly when called from within code.
• Second is, instead of writing a C++ function for plotting, I am interested to have a scripting language (like autoexp.dat or a VBScript) to give the internal data of the C++ object without writing any wrapper, so that I can use the script to store the data in a file or plot it.

In general I am interested to have something like Matlab or Ch IDE, where I can plot certain variable externally when the program is at a debug break.

解决方案

Since VS 2005, Visual Studio has included Visualizers, which could almost have been designed specifically for your problem. MSDN explains the concept better than I can:

Visualizers are a new component of the Visual Studio debugger user interface. A visualizer creates a dialog box or other interface to displays a variable or object in a meaningful way that is appropriate to its data type. For example, an HTML visualizer interprets an HTML string and displays the result as it would appear in a browser window, a bitmap visualizer interprets a bitmap structure and displays the graphic it represents, and so on. Some visualizers allow you to edit as well as view the data.
