Conversation class a member function:

 void CBBCDlg: : OnBnClickedCheck1 () 
{show="show"; 
PMFrame=(CMainFrame *) GetParentFrame (); 
PMFrame - & gt; The show=show; 
PMFrame - & gt; Invalidate (). 

//TODO: add the control notification handler code 
} 

Draw a member function of a class

 void CDrawView: : ontouch * pDC (CDC) 
{
CDocument * pDoc=GetDocument (); 
//TODO: add in this rendering code 
PMFrame=(CMainFrame *) GetParentFrame (); 
PMFrame - & gt; The show=show; 
Cstrings STR=pMFrame - & gt; The show; 
MessageBox (STR); 
//pMFrame - & gt; Invalidate (). 

If (show=="show") 
{DrawCoordinate (pDC, 3); 
} 
} 

Without errors, how to realize the data sharing between them? Drawing class show value is not equal to dialogue in the class show.
Great god help me, this is my curriculum design problems, next week will reply, thank you

CodePudding user response:

Use a custom message to share data

CodePudding user response:

It is recommended to use global variables

CodePudding user response:

In stdafx.
in the CPPCstrings show=_T (" ");
In stdafx.
in the hExtern cstrings show;
A global variable with respect to OK
You for the broken dick program can be simplified as

 void CBBCDlg: : OnBnClickedCheck1 () 
{
The show="show"; 
GetParentFrame () - & gt; Invalidate (). 
} 

Void CDrawView: : ontouch * pDC (CDC) 
{
CDocument * pDoc=GetDocument (); 
MessageBox (show); 
If (show=="show") 
{
DrawCoordinate (pDC, 3); 
} 
} 

CodePudding user response:

Are you a single document or multiple document?

CodePudding user response:

Global variables to go,

In addition, said a problem, you old man's house in ontouch MessageBox is dead
