Constructs a CSingleDocTemplate object.
CSingleDocTemplate(
UINT nIDResource,
CRuntimeClass* pDocClass,
CRuntimeClass* pFrameClass,
CRuntimeClass* pViewClass
);
Parameters
nIDResource
Specifies the ID of the resources used with the document type. This may include menu, icon, accelerator table, and string resources.The string resource consists of up to seven substrings separated by the '\n' character (the '\n' character is needed as a placeholder if a substring is not included; however, trailing '\n' characters are not necessary); these substrings describe the document type. For information about the substrings, see CDocTemplate::GetDocString. This string resource is found in the application's resource file. For example:
// MYCALC.RC
STRINGTABLE PRELOAD DISCARDABLE
BEGIN
IDR_MAINFRAME "MyCalc Windows Application\nSheet\nWorksheet\n Worksheets (*.myc)\n.myc\nMyCalcSheet\n MyCalc Worksheet"
END
You can edit this string using the string editor; the entire string appears as a single entry in the String Editor, not as seven separate entries.
For more information about these resource types, see the String Editor.
pDocClass
Points to the CRuntimeClass object of the document class. This class is a CDocument-derived class you define to represent your documents.pFrameClass
Points to the CRuntimeClass object of the frame window class. This class can be a CFrameWnd-derived class, or it can be CFrameWnd itself if you want default behavior for your main frame window.pViewClass
Points to the CRuntimeClass object of the view class. This class is a CView-derived class you define to display your documents.
Remarks
Dynamically allocate a CSingleDocTemplate object and pass it to CWinApp::AddDocTemplate from the InitInstance member function of your application class.
Example
// The following code fragment is from CMyWinApp::InitInstance.
// CMyWinApp is derived from CWinApp.
// Establish the document type
// supported by the application
AddDocTemplate(new CSingleDocTemplate(IDR_MAINFRAME,
RUNTIME_CLASS(CMyDoc),
RUNTIME_CLASS(CMainFrame), // main SDI frame window
RUNTIME_CLASS(CMyView)));
// The following code fragment is from CMyWinApp::InitInstance.
// CMyWinApp is derived from CWinApp.
// Normally, an application creates a document
// template and registers it with MFC as a part
// of its initialization.
// IDR_SAMPLERESOURCE is a resource ID string;
// see the CDocTemplate class overview documentation
// for more information on its format.
// The next three parameters use the RUNTIME_CLASS()
// macro to get runtime type information for the doc,
// frame, and view classes that will be associated by
// the template.
CSingleDocTemplate* pDocTemplate;
pDocTemplate = new CSingleDocTemplate(IDR_MAINFRAME,
RUNTIME_CLASS(CMyDoc),
RUNTIME_CLASS(CMainFrame), // main SDI frame window
RUNTIME_CLASS(CMyView));
if (!pDocTemplate)
return FALSE;
// After the following call, MFC is aware of the doc
// template and will free it when the application is
// shut down. The doc templates known to MFC will
// automatically be used when CWinApp:OnFileOpen() or
// CWinApp::OnFileNew() are called.
AddDocTemplate(pDocTemplate);
