I have a View which is derived from the SyntaxEditorView class. My class does not have a CDocument associated with it.

In the Syntax Editor control, I am loading a different file in the same control when the user changes what they are looking at.

After a file is loaded and text inserted into the control. I need to scroll to the bottom of the Syntax Editor window after a file is loaded for a "tail"-like behavior for log files.

To accomplish this, I have to do the following:

GetEditCtrl().Scroll(0,0);
GetEditCtrl().SetScrollRange(SB_VERT, 1, 1);

GetEditCtrl().Scroll(0, pXTPSyntaxEditBufferManager->GetRowCount());
int nPos = GetEditCtrl().GetScrollPos(SB_VERT);
GetEditCtrl().GoToRow(nPos);
GetEditCtrl().Scroll(0, nPos);

The problem is that if the previously loaded file is larger than the current file, the control is still retaining some old values that prevent the scrolling from working properly.

Perhaps this is a bug...or maybe my code will help someone else out.

Adding that seems to have no affect.

Not sure how that would allow me to scroll the the last line (bottom) of the file/document.
