控件问题

[995]

请问如何在单文档或多文档中的客户区中ActiveX加控件

MSDN这样说:

To dynamically create an ActiveX control in a non-dialog window

1.Insert CIRC2.H in CMYVIEW.H, just before the CMyView class definition:
#include "circ2.h"

2.Add a member variable (of type CCirc2) to the protected section of the CMyView class definition located in CMYVIEW.H:
class CMyView : public CView
{
...
protected:

CCirc2 m_myCtl;
...
};

3.Add a WM_CREATE message handler to class CMyView.


4.In the handler function, CMyView::OnCreate, make a call to the control’s Create function using the this pointer as the parent window:
int CMyView::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (MyView::OnCreate(lpCreateStruct) == -1)
return -1;

// ****** Add your code below this line ********** //

m_myCtl.Create(NULL, WS_VISIBLE,
CRect(50,50,100,100), this, 0);
m_myCtl.SetCaption(_T(“Control created”));

// ****** Add your code above this line ********** //

return 0;
}

5.Rebuild the project. A Circ2 control will be created dynamically whenever the application’s view is created.

跟加入一个标准控件相似，不过使用ActiveX控件时应在你的项目中加入一些与控件有关的文件，这个过程你可先在一个对话框中添加ActiveX控件实现，生成ActiveX的文件后从对话框中删除控件即可。
