[C ++] [windows forms]我无法连接类 [英] [C ++] [windows forms] I can not connect classes
问题描述
您好,我是
我有一个MyForm.h类和一个Dialog.h类。
MyForm.h:
在MyForm.h中尝试以下更改:
// #include" Dialog.h" - 已评论,不需要
。 。 。
private:System :: Void menuSearch_Click(System :: Object ^ sender,System :: EventArgs ^ e);
在MyForm.cpp中添加:
System :: Void MyForm :: menuSearch_Click(System :: Object ^ sender,System :: EventArgs ^ e)
{
Dialog ^ dialog = gcnew Dialog();
dialog-> ShowDialog();
}
同时从Dialog.cpp中删除 WinMain 。 (假设 MyForm 是主要形式)。 该程序中应该是一个
WinMain 。
如果你想从 Dialog 访问 MyForm ,那么而不是
'gcnew MyForm'使用从 Dialog 传递的参数,如下所示(在
menuSearch_Click 中):
  ;  Dialog ^ dialog = gcnew Dialog();
dialog-> ShowDialog(this);
在 btnSearch_Click :
<跨度>&NBSP;&NBSP; MyForm ^ myForm =(MyForm ^)所有者;
Hello,
I have a class MyForm.h and a class Dialog.h.
MyForm.h:
Try the following changes in MyForm.h:
// #include "Dialog.h" -- commented, not needed
. . .
private: System::Void menuSearch_Click( System::Object ^ sender, System::EventArgs ^ e );
In MyForm.cpp add this:System::Void MyForm::menuSearch_Click( System::Object ^ sender, System::EventArgs ^ e )
{
Dialog ^ dialog = gcnew Dialog();
dialog->ShowDialog();
}
Also remove WinMain from Dialog.cpp. (Assuming MyForm is the main form). It should be a single WinMain in the program.If you want to access MyForm from Dialog, then instead of ‘gcnew MyForm’ use a parameter passed from Dialog, something like this (in menuSearch_Click):
Dialog ^ dialog = gcnew Dialog();
dialog->ShowDialog( this );In btnSearch_Click:
MyForm ^ myForm = (MyForm^)Owner;
