MFC projects up vote 1 down vote favorite I have a Dialog with a CListCtrl with some data, below is a button. My second project is a dialog with a tri-state checkbox. Now I want to couple both projects, so when selecting a list item and clicking the button the tristate dialog appers showing something. Well, I added the second project to another one and changed error c2065 'string' undeclared identifier its type to .dll, but receive a build error error C2065: 'IDD_MFCAPP2_DIALOG' : undeclared identifier IDD_MFCAPP2_DIALOG is the id of he checkbox dialog. When adding the project both id's had the same value, so I changed this in resource.h manually to a different one, but it did not solve the problem. The projects work very well separately. What do I miss? UPDATE: I have reduced the project to a minimum, the problem is the same MFCApp1Dlg.h class CMFCApp1Dlg : public CDialogEx { // Construction public: CMFCApp1Dlg(CWnd* pParent = NULL); // standard constructor // Dialog Data enum { IDD = IDD_MFCAPP1_DIALOG }; protected: virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support // Implementation protected: HICON m_hIcon; // Generated message map functions virtual BOOL OnInitDialog(); afx_msg void OnPaint(); afx_msg HCURSOR OnQueryDragIcon(); DECLARE_MESSAGE_MAP() public: afx_msg void OnBnClickedButtonChange(); CButton m_BtnChange; }; Its cpp file only contains the standard things. Just the button handler calls other app void CMFCApp1Dlg::OnBnClickedButtonChange() { CMFCApp2Dlg dlg; if (dlg.DoModal()) { // do something... } } MFCApp2Dlg.h looks the same class CMFCApp2Dlg : public CDialogEx { // Construction public: CMFCApp2Dlg(CWnd* pParent = NULL); // standard constructor // Dialog Data enum { IDD = IDD_MFCAPP2_DIALOG }; protected: virtual voi

Tthe code that you posted looks as if you've simply cut'n'pasted your code as the AFX declaration is different to the name of your class, and you've tried to insert a resouce ID that does not exist : Code: class CDialog1 : public CDialog { //
