After a toolbar button is pressed the status bar message for the button is updated again. At that time, the mouse may already have moved to a complete other location. But the MFCStatusBar still wants to display the status bar message for the button ID again at that time. The 'Ready'-status bar text is displayed shortly after

Visual Studio 2010 SP1

Reliability

Open any MFC application that uses the new CMFCStatusBar class from the MFC feature pack.

Just press the 'File Open'-button on the tool bar. At that moment, the icon is displayed as 'pressed down'. Then the 'File Open'-dialog appears.

After pressing the 'cancel'-button using the mouse (for which of course you'll have to move the mouse cursor position), the status bar text for the 'File Open'-button is displayed again, which is wrong since the mouse cursor position isn't positioned above the tool bar button anymore.

Windows Vista

Code is run from the function:
void CMFCToolBar::OnLButtonUp(UINT nFlags, CPoint point)

The button command is executed from this function by the line:
GetOwner()->SendMessage(WM_COMMAND, nIDCmd); // send command

After the command has been executed (e.g. closing the 'File Open'-dialog), the following function will be called:
OnMouseMove(0, point);

Now the following line is executed by OnMouseMove(0, point):
ShowCommandMessageString(pButton->m_nID);

I would not expect the status bar message to be displayed again when the mouse cursor position was changed in the mean time.

Hello,

I find it strange that you cannot reproduce this issue, because it's so simple. But never mind, I've posted a sample project as well as a video file. Watch the status bar text as soon as the 'Cancel'-button is pressed in the 'File Open'-dialog. It will show 'open an existing file' for a short while! That's the bug I mentioned, since the mouse cursor isn't positioned anymore above the 'Open'-button on the tool bar.

Thank you!

I'm sorry, I incorrectly set the product version to VS2010 although I'm using VS2010 SP1.
This has been updated.
