How to call CLR control in MFC dialog box

At present, our new version of database application is completely developed with VC. It's not easy to find a good VC developer in our town. So, a long time ago, I began to think about VC and. NET can be mixed programming, which gives me more opportunities to find more suitable programmers in personnel recruitment. I am glad to find that VisualStudio2005 provides us with such an opportunity. MFC can easily call codes written in VB.NET, C# or other CLR languages, so it can be widely used. NET language, thus improving the development efficiency of our products.

Of course, it seems rare to develop a large database application with VC. In database processing, VB, C#, DELPHI and JAVA all have advantages over VC. We chose VC to develop the database program. First, because our products are mainly oriented to medical image processing, video processing and video transmission, we must use VC, and all developers in the company are familiar with VC. Second, optimistic about VC development environment is more suitable for object-oriented thinking. Most of us work through the class view of VC, and the document view structure of VC is more suitable for on-demand database management programs. Third, c++ has many excellent template libraries and better generic design, which will solve big problems at critical times.

The following text is taken from MSDN and describes how to call. NET in MFC. The controls in the example are not only suitable for user-defined controls, but also can use various built-in standard controls. Net. For example, we can call directly. Net FrameWork in MFC dialog box. Define a variable cwInformControl.

void CVCDlg::DoDataExchange(CDATA exchange * pDX)

{

CDialog::DoDataExchange(pDX)；

DDX_ManagedControl(pDX，IDC_CTRL 1，m _ ctrl 1)；

DDX_ManagedControl(pDX，IDC_TREE，m _ TREE)；

}

In this way, you can add nodes to TreeView in the initialization function of the dialog box:

Tree node trroot = m _ tree. get control()-& gt； Node-> Add ("root node");

treenode ^ tr child = tr root-& gt； Node-> Add ("the first child node");

Run the application, and you can see the added tree control and two nodes displayed in the dialog box.
