[MFC Newbie] workflow for calling function from InitInstance

Hi everybody.

As some of you might have read in my previous thread (http://www.codeguru.com/forum/showthread.php?t=476458) I'm trying to add a commandline interface to an existing MFC application.

I'm new to MFC, but do have some C++ experience.

Even though I'm new to MFC, I've found out that it's a SDI app, and I've read about the relationship between the CMainFram, CView and CDocument classes.

Here is what I want to do: Once I locate a switch (or option) in my commandline, I want to execute a function from my InitInstance() - code exampel below:

Code:

---

BOOL CMyMlvApp::InitInstance()
{
        ....

        CommandLineParser cmdInfo;
        ParseCommandLine(cmdInfo);

        if(cmdInfo.IsLoad())
        {
                //Here I want to call the load-function
                AfxMessageBox("Hello World from Load");
        }
        if(cmdInfo.IsVerify())
        {
                //Here I want to call the verify-function
                AfxMessageBox("Hello World from Verify");
        }
        if(cmdInfo.IsReset())
        {
                //Here I want to call the reset-function
                AfxMessageBox("Hello World from Reset");
        }

        // Dispatch commands specified on the command line
        if (!ProcessShellCommand(cmdInfo))
                return FALSE;

        ....
}

---

I've located the functions I want to call in the CDocument class

Code:

---

void CMyMlvDoc::OnFunctionVerify()
{
        CRtMem RtMem(&m_MlvConfig,m_ProcessorId);
       
        if (RtMem.m_Status==RT_OK)
        {
                CVerifyDlg dlg(&RtMem,&m_hexlineList);
               
                dlg.m_VerifyDescription=GetTitle();
               
                dlg.DoModal();
        }
        else
                AfxMessageBox("Verify failed");
}

---

I have tried creating an object of CMyMlvDoc, and calling the "OnFunctionVerify()", but it's protected. And I've tried copying the content of the function directly into the InitInstance - no succes.

So what I want to know is: how is the workflow for calling this function in my InitInstance-function?

If you need any more information, let me know

The "workflow" is:

Quote:

---

ProcessShellCommand calls CWinApp::OnFileNew to start the application with an empty document if no file name was entered on the command line, or CWinApp::OpenDocumentFile to start the application and load a document if a document name was specified. It is during this phase of the program's execution that the framework creates the frame window, document, and view objects using run-time class information contained in the document template. ProcessShellCommand returns TRUE if the initialization succeeded and FALSE if it did not. A FALSE return causes InitInstance to return FALSE also, which shuts down the application.

In my InitInstance-function, I've located the following block:

Code:

---

        CMySingleDocTemplate* pDocTemplate;
        pDocTemplate = new CMySingleDocTemplate(
                IDR_MAINFRAME,
                RUNTIME_CLASS(CMyMlvDoc),
                RUNTIME_CLASS(CMainFrame),      // main SDI frame window
                RUNTIME_CLASS(CMyMlvView));
        AddDocTemplate(pDocTemplate);

---

Could this pDocTemplate be used to acces the function? And how?

Hi Victor.

From where are you quoting this? I would like to read the full text :)

And as you can see in the post I made simultaniously with yours, I'm pretty sure the InitInstance opens a Document for me - right?
