推荐答案
在Form8.h文件中是否正确声明了Form8？
Is Form8 properly declared in Form8.h file ?
您还可以使用"转到定义"来验证您的代码是否可用于您的代码。视觉工作室的功能。
You can also verify whether a class named Form8 is available to you code by using "go to definition" feature of visual studio.
我认为您在代码中声明Form8和其他表单的方式有问题。
I think there is something wrong with how you declared Form8 and other forms being referenced in your code.
