Hello!

I have a strange problem. I have a floating toolbar whose layout is =
fixed to two columns. This floating toolbar's size is also fixed. It is =
getting created properly.  But whenever I click on some other button in =
the toolbar, or try to move it by holding the titlebar, it resizes =
itself to the default, i.e., single horizontal row.  I am creating the =
toolbar by using a large bitmap and cutting the bitmap into equal pieces =
for the individual bitmaps for the toobar buttons.  For this purpose, I =
am using a derived class from CToolBar. I use the following code to =
create the toolbar:

BOOL CMainFrame::CreatePalette()  {
... ... ...
... ... ...
if (!myToolBar.Create(this, WS_CHILD | WS_VISIBLE | CBRS_SIZE_FIXED=20
| CBRS_TOP, CBRS_TOOLTIPS) || !myToolBar.LoadBitmap(MY_BITMAP_ID)=20
|| !myToolBar.SetButtons(myPalette, sizeof(myPalette) / sizeof(UINT)))
{
	return FALSE;
}
... ... ...
return TRUE;
}

Here, myPalette is a static array of UINTs which contain the individual =
ids of the bitmaps of the toolbar.

What is the cause and what could be the solution? Somebody .. ?

Cheers,

How did you set it to two columns?

Did you set the m_nColumns member to 2?

You're chopping up the bitmap yourself?  Why?

I'm not sure I see anything here that causes the tollbar to be split
into two columns.

Have you tried looking at the CTRLBARS sample?  It makes a toolbar 
show up with two columns, and it does just fine.
