the dialog was not modal, but in fact, I'm trying to use the PostNCDestroy override function and it seems to work well.

CMyDialog::CMyDialog(CWnd* pParent /*=NULL*/) : CDialog(CMyDialog::IDD, pParent)
{
    Create(IDD);
}
 
void CMyDialog::PostNcDestroy() 
{
    delete this;	
    CDialog::PostNcDestroy();
}
...
CMyDialog *pDlg;
    
pDlg = new CMyDialog;
pDlg->ShowWindow(SW_SHOW);    
...
pDlg->DestroyWindow();

int CString::Remove( TCHAR ch );

Return Value

The count of characters removed from the string. Zero if the string isn't changed.

Parameters

ch

The character to be removed from a string.

Remarks

Call this member function to remove instances of ch from the string. Comparisons for the character are case-sensitive.

Example

//remove the lower-case letter 't' from a sentence:

CString str("This is a test.");
int n = str.Remove('t');
ASSERT(n == 2);
ASSERT(str == "This is a es.");

or any other way to only let the user input only a-z and A-Z characters in the editbox?
