vc中如果创建窗口时设置的基类是CRecordSet，如何调用函数去显示这个窗口？

因为CRecordSet类是CWnd的派生类所以我想调用createwindow函数，但是如何传参数不会，请高手指导。

追问：我写错了，应该是CRecordView汗。。。。。。。我要引用数据库，所以基类得是CRecordView。

答案：class CRecordset : public CObject
{
	DECLARE_DYNAMIC(CRecordset)

// Constructor
public:
	CRecordset(CDatabase* pDatabase = NULL);

public:
	virtual ~CRecordset();

	enum OpenType
	{
		dynaset,        // uses SQLExtendedFetch, keyset driven cursor
		snapshot,       // uses SQLExtendedFetch, static cursor
		forwardOnly,    // uses SQLFetch
		dynamic         // uses SQLExtendedFetch, dynamic cursor
	};

	enum OpenOptions
	{
		none =                      0x0,
		readOnly =                  0x0004,
		appendOnly =                0x0008,
		skipDeletedRecords =        0x0010, // turn on skipping of deleted records, Will slow Move(n).
		noDirtyFieldCheck =         0x0020, // disable automatic dirty field checking
		useBookmarks =              0x0100, // turn on bookmark support
		useMultiRowFetch =          0x0200, // turn on multi-row fetch model
		userAllocMultiRowBuffers =  0x0400, // if multi-row fetch on, user will alloc memory for buffers
		useExtendedFetch =          0x0800, // use SQLExtendedFetch with forwardOnly type recordsets
		executeDirect =             0x2000, // Directly execute SQL rather than prepared execute
		optimizeBulkAdd =           0x4000, // Use prepared HSTMT for multiple AddNews, dirty fields must not change.
		firstBulkAdd =              0x8000, // INTERNAL to MFC, don't specify on Open.
	};
	virtual BOOL Open(UINT nOpenType = AFX_DB_USE_DEFAULT_TYPE,
		LPCTSTR lpszSQL = NULL, DWORD dwOptions = none);
	virtual void Close();

// Attributes
public:
	HSTMT m_hstmt;          // Source statement for this resultset
	CDatabase* m_pDatabase;       // Source database for this resultset

	CString m_strFilter;        // Where clause
	CString m_strSort;      // Order By Clause

	BOOL CanAppend() const;     // Can AddNew be called?
	BOOL CanRestart() const;    // Can Requery be called to restart a query?
	BOOL CanScroll() const;     // Can MovePrev and MoveFirst be called?
	BOOL CanTransact() const;   // Are Transactions supported?
	BOOL CanUpdate() const;     // Can Edit/AddNew/Delete be called?
	BOOL CanBookmark() const;       // Can Get/SetBookmark be called?

	const CString& GetSQL() const;      // SQL executed for this recordset
	const CString& GetTableName() const;        // Table name

	BOOL IsOpen() const;        // Recordset successfully opened?
	BOOL IsBOF() const;     // Beginning Of File
	BOOL IsEOF() const;     // End Of File
	BOOL IsDeleted() const;     // On a deleted record
....

};


我不知道你是从哪里看到它是CWnd的派生类的。。。。

你看下它有没有createwindow这样的成员？

其他：好专业 好难 
按Ctrl+w
出现引导对话框,
右边创建新类
在第一行的editor里填写新的类的名称
在第3行的combobox里选择CDialog
确定,ok

另:
要在Mainfrm.cpp的前头加上你声明CInputDlg这个类的头文件.
举例:#include "InputDlg.h"
要编程学会看英文,undeclared identifier 就是不明确的声明.
