Topic: Calling GetActiveDocument from CMainFrame

Subject: Calling GetActiveDocument from CMainFrame

I'm trying to call GetActiveDocument() from within a CMainFrame class derived from CXTPFrameWnd, but the call always returns NULL. Tracing into the GetActiveDocument() call, it appears to return NULL because the View is also NULL.

I'm working on an app using a ShortcutBar. Just to see if I could narrow down the problem, I've taken the Codejock ShortcutBar sample app and added a call to GetActiveDocument() in the CMainFrame::OnCustomize member and I still see NULL returned for the document. I chose this member function only because everything should have been completely initialized by the time is was available.

Can anyone give me a clue as to what I'm doing wrong? I'm working with XTP 11.1.0.

Thank you,

Glenn

Hi,

if you use MDI its correct behavior.

call GetActiveFrame()->GetActiveDocument() instead.

oleg,

I'm sorry, but this does not fix it. The document is still returned as NULL even in the Codejock ShortcutBar sample.

Just to clarify, what I've done is added a line of code to the standard Codejock ShortcutBar sample as shown below:

void CMainFrame::OnCustomize()

{

GetActiveFrame()->GetActiveDocument();

// get a pointer to the command bars object.

CXTPCommandBars* pCommandBars = GetCommandBars();

if (pCommandBars == NULL)

return;

...........

I've added the code here only as a test to see if I can get the active document once the app is up and running. Inside GetActiveDocument(), the call to GetActiveView() returns NULL and therefore returns NULL for the document as well.

I'm not sure if it's ShortcutBar related, but this works fine in other applications.

Thanks,

Glenn
