i have created a simple project in Visual studio 2008 after installing the feature pack.
i found that there are new classes for toolbar, menu etc viz: CMFCToolbar, CMFCMenuBar, ...
now if i want to use the old class CToolBar and create a toolbar, then DockControlBar() function fails.
is there no way to use CToolBar class?
sample code:
after i create the toolbar, i dock as follows
m_wndToolBar.EnableDocking(CBRS_ALIGN_ANY);
EnableDocking(CBRS_ALIGN_ANY);
DockControlBar(&m_wndToolBar);
thanks

You can use of ShowWindow(SW_HIDE) or you can set visible option to false of your control on the property window.

The previous answers were correct but remember that a hidden button is still enabled.

1. change the extension of the image to .ico and put the image in your res folder.
2. in the resource editor select the option called icon
right click and select import
select the image from the res folder
set the icon in the constructor of your dilaogdlg.cpp file
m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);

hi i m using BitBlt for preview dc my drawing coming distorted while in normal display it comes proper.
i have used memDC for drawing and using BitBlt for copying on display dc. i have to use memDC to avoid flickering.
used StrechDibits also same result.
Plz help and suggest me flicker free solution.
thnks

i think u didnt get me.. i have used memDC fot flicker free drwaing but it does not work in case PrintPreview. I have used BitBlt for copying from memDC to pDC. But not in case of print preivw.
if i do drawing does not come properly.
i think there is some problem with BitBlt in case of preview DC.
thanks

What exactly do you mean by

?
Maybe put up some code or -don't know if it is possible or allowed or a nice thing to do- screenshots or maybe links to screenshots for us to see what you mean.

void CCalendarControlView::DrawOnDC(CDC * pDC, int isPrinting)
{
if (pDC->IsKindOf(RUNTIME_CLASS(CPreviewDC)))
{
memDC.CreateCompatibleDC(pDC);
bmp.CreateCompatibleBitmap(pDC, rc.Width(),rc.height());
memDC.SelectObject(&bmp);
pMemDC = &memDC;
}
//Now m doing some drawing on pMemDc
and at last after drawing for display
pDC->BitBlt(0,0,rc.Width(),rc.Height(),pMemDC,SRCCOPY);
}
and onPrintPreviewButtton()
{
AFXPrintPreview(this);
}
m doing this getting correct drawig in case of niormal display but not in case or print preivew.

Explain what your print preview looks like. You could try using SetAttribDC[^] or SetOutputDC[^], but without seeing your results i am just guessing around.

did u get the code i have pasted.
i m nt getting wt u have understood and wt u didnt.
void CCalendarControlView::OnFilePrintPreview()
{
AFXPrintPreview(this);
}
CRect rc = rcClient;
void CCalendarControlView::DrawOnDC(CDC * pDC, int isPrinting)
{
memDC.CreateCompatibleDC(pDC);
bmp.CreateCompatibleBitmap(pDC, rc.Width(), rc.Height());
memDC.SelectObject(&bmp);
pMemDC = &memDC;
}
//Now drawinf something on pMemDC
//Now BitBlt
pDC->BitBlt(0, 0, rc.Width(), rc.Height(), pMemDC, 0, 0, SRCCOPY);
this works fine in case of display in window but nuthing comes on OnFilePrintPreview()
if ny prob in getting code please let me knw..
thanx for ur effort

Google doesn't bring up much for AFXPrintPreview, and i don't know it. Are you sure your drawing code gets called when you call that AFXPrintPreview method?

ya i m sure as it works perfectly in case i do not use memery dc in case of print preview and directly do the drawing on display dc.
actually it is given in mfc itself all the code DoPrintPreview and CPrintDialog etc code has been written and these functions is being called.
if it works in case display dc i dnt knw why it doesnt work in case of memory dc and copying to display dc
thanks for ur effort.

Your problem might be the rectangle you use for the drawing. Could it be that your buffer bitmap does not get the right size? Also, doing a print preview isn't exactly the same as drawing on the screen, as far as i know, since printers have different page sizes, DPIs, whatevers, if i were you i would try experimenting with that SetAttribDC[^], try doing MemDC.SetAttribDC(pDC) before you start drawing and MemDC.ReleaseAttribDC()[^] afterwards and see if anything changes.

well i did that also but that didnt help.
even wt u r telling can be a case but how to get correct size i just have the info that in case if print preview the pDC i get in OnDraw() is the one with m_bPrinting = 1 means its a printer dc. it might be due to AFXPrintPreview() it runs some code written in mfc itself in viewcore.cpp viewprev.cpp. u might have these files also if u have latest visual studio at
C:\Program Files\Microsoft Visual Studio 9.0\VC\atlmfc\src\mfc
ny idea how can i check the size m passing to buffer dc is correct or not
thanks

Try using CDC::GetDeviceCaps[^], giving it maybe HORZRES and VERTRES or so to get the size of the DC's surface, or maybe HORZSIZE and VERTSIZE. Just note something, when using printer DC's, the size of the surface might be HUGE. Actually, do you really need to draw your print preview on a buffer?

i have did this. even though prob is same nothing is coming.
i have to use buffer as there is so much flicering comin in print preview window as resizing and all due to direct drawing on display dc.
if (pDC->IsKindOf(RUNTIME_CLASS(CPreviewDC)))
{
//using buffer and copying from mem DC to preview DC causes problem. so
//we directly draw on preview DC during preview.
memDC.CreateCompatibleDC(pDC);
bmp.CreateCompatibleBitmap(pDC, pDC->GetDeviceCaps(HORZRES), pDC->;GetDeviceCaps(VERTRES));
memDC.SelectObject(&bmp);
memDC.SetAttribDC(pDC->;GetSafeHdc());
//pMemDC = pDC;
pMemDC = &memDC;
}
