BOOL NewDialg: : Create () 
{
Return CDialog: : Create (IDD_DIALOG1 m_pview); 
} 

Compile error
Error C2664: 'BOOL CDialog: : Create (LPCTSTR, CWnd *)' : always convert parameter 1 from ' 'to' LPCTSTR '

Given CDialog

 class CDialog: public CWnd 
{
Public: 
Virtual BOOL Create (LPCTSTR lpszTemplateName, CWnd * pParentWnd=NULL); 
Virtual BOOL Create (UINT nIDTemplate, CWnd * pParentWnd=NULL); 
} 

Analysis of the reason is CDialog: : Create (IDD_DIALOG1 m_pview); Parameters of call was the first to Create, so wrong, but why don't you call the Create the second, I look at the others also wrote the code,

CodePudding user response:

The second the first parameter of the Create type UINT is unsigned integer alias
Typedef unsigned int UINT;

IDD_DIALOG1 is dialog ID
# define IDD_DIALOG1. 310

CodePudding user response:

Their top, trouble each great god to have a look

CodePudding user response:

It's been two hours,,,

CodePudding user response:

In the edit box to add dialog resources, ID is modified to IDD_DIALOG1, then your code can use, if have resources, the parameters of the functions of IDD_DIALOG1 replace existing resource ID

Have added the dialog resource and ID is IDD_DIALOG1

CodePudding user response:

I already despair,,,

CodePudding user response:

NewDialg. CPP in # include "resource. H" try, may be ID has not been normal recognition

CodePudding user response:

Return CDialog: : Create (MAKEINTRESOURCE (IDD_DIALOG1), m_pview); ?

CodePudding user response:

 BOOL CAboutDlg: : Create () 
{
The CWnd * pview=0; 
Return CDialog: : Create (IDD_ABOUTBOX pview); 
} 

There is nothing wrong?

CodePudding user response:

 BOOL CAboutDlg: : Create () 
{
The CWnd * pview=AfxGetMainWnd (); 
Return CDialog: : Create (IDD_ABOUTBOX pview); 
} 

There's nothing wrong with?

CodePudding user response:

Can determine the compiler error is
Return CDialog: : Create (IDD_DIALOG1 m_pview);
This line?

CodePudding user response:

A test, first of all, use the MAKEINTRESOURCE, the unit of the computer to compile, home computer not.

A lot of data, then baidu type conversion of the visual studio is said to be more strict, the type will not default compatible, need to enforce type conversion,
Return CDialog: : Create (LPCTSTR IDD_DIALOG1, (CWnd *) m_pview); At this time to compile,
But
Return CDialog: : Create ((UINT) IDD_DIALOG1, (CWnd *) m_pview); Or compiled not through, that is to say here or just call the first CDialog: : Create (), not call for a second, a great god answers, why not call the second? How can I call for a second?


Extended another problem that MFC single document to the default view class CMFCStudyView in the client area click, calling a modal dialog box NewDialg, m_pdlg is CMFCStudyView private member function, no initialization,
Why the trigger OnLButtonDown, direct access to the following m_pdlg - & gt; SetActiveWindow (); I did not create m_pdlg, so after the operation, direct crash, even in the constructor CMFCStudyView
Initialized to NULL, as well as into m_pdlg - & gt; SetActiveWindow (); The last crash directly,
Void CMFCStudyView: : OnLButtonDown (UINT nFlags, CPoint point)
{
If (m_pdlg!=NULL)
M_pdlg - & gt; SetActiveWindow ();//click again, the activation dialog
The else
{
M_pdlg=new NewDialg (this);//for the first time, click the create a modal dialog box
M_pdlg - & gt; The Create ();
}
The CView: : OnLButtonDown (nFlags, point);
}
But create a modal dialog box can be directly run, why?
Void CMFCStudyView: : OnLButtonDown (UINT nFlags, CPoint point)
{
M_pdlg=new NewDialg (this);//for the first time, click the create a modal dialog box
M_pdlg - & gt; The Create ();

The CView: : OnLButtonDown (nFlags, point);
}

9, 10, floor is vc6, no compile wrong!
