The error C2065: 'GetDIgltem: undeclared identifier-CodePudding

Dinglu \ dingluDlg CPP (139) : error C2065: 'GetDIgltem: undeclared identifier
Why is this excuse me

CodePudding user response:

GetDIgltem belongs to the CWnd class member functions, when using, should first obtain the CWnd object (CDialog inherited from CWnd),

For example:

 void test (CYourDlg * pDlg) 
{
CEdit * editbox=(CEdit *) pDlg - & gt; GetDlgItem (IDC_EDIT1); 
//other code 
}

When call test, need incoming dialog object pointer,

Also can be the following situation:

 void CYourDlg: : OnBnClickedCancel () 
{
CEdit * editbox=(CEdit *) GetDlgItem (IDC_EDIT1); 

//this is CYourDlg class member functions, will be hidden into a this pointer, 
//(CEdit *) GetDlgItem (IDC_EDIT1) is equivalent to (CEdit *) this - & gt; GetDlgItem (IDC_EDIT1) 
}

if you have any help to you, please adopt the answer, thank you

CEdit * editbox= (CEdit *) GetDlgItem (IDC_EDIT1);
Where did you call GetDlgItem () your dialog box class should be no problem if you check the ID is the controls in the RC file ID
