本文介绍了在表单之间切换vc ++ 2010的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我使用Visual Studio 2010，我想在C ++中的两种形式之间切换。我一直在做一些搜索，我找不到任何解决方案，这不是所有关于c＃和视觉基本。
I am using Visual Studio 2010 and I want to switch between two forms in C++. I have been doing some googling and I couldn't find any solution to this without it being all about c# and visual basic.
我得到这个错误到目前为止：
I have been getting this error so far:
错误12错误C2227：' - > ShowDialog的左侧必须指向class / struct / union / generic type
错误4错误C2065：'Form2'：未声明标识符
错误11错误C2065：'f1'：未声明标识符
错误5错误C2061：语法错误：标识符'Form2'
错误10错误C2061：语法错误：标识符'Form1'
Error 12 error C2227: left of '->ShowDialog' must point to class/struct/union/generic type Error 4 error C2065: 'Form2' : undeclared identifier
Error 11 error C2065: 'f1' : undeclared identifier
Error 5 error C2061: syntax error : identifier 'Form2'
Error 10 error C2061: syntax error : identifier 'Form1'
>
Form 1：
The only thing I put in my code is
Form 1:
#include "Form2.h"
和按钮事件
Form2^form2 = gcnew Form2();
form2->ShowDialog();
this->Hide();
和表格2
#include "Form1.h"
p>
and for the button event
Form1^f1 = gcnew Form1();
this->Hide();
f1->ShowDialog();
这是否正确？这是我的第一篇文章，所以告诉我还需要添加到
帮助使它更清楚
编辑：
Form2
Is this correct at all? This is my first post ever so tell what else I need to add in to help make it clearer Form2

推荐答案
使用命名空间MBED4写入
In your implementation file you need to write
using namespace MBED4;
或
using MBED4::Form2;
之前
Form2^form2 = gcnew Form2();
或写
MBED4::Form2^form2 = gcnew MBED4::Form2();
form2->ShowDialog();
this->Hide();
