I need to use a function which draws to a window using it's HWND handle, now I need to draw to a bitmap object rather than the window (It's now server based and there are no windows).

Is this possible? How would I go about it?

Thanks in advance!

the first thing you should do is:

HDC hDc = GetDC(hWnd);

then you can create a compatible bitmap, select it into your DC, and start drawing on it.

I was hoping to do this without a window but if I have to create a window then that will be OK but I have been trying to make this work for 2 days now with no luck.

If I use the code:

<br />
// Syntax: DrawEx( HWND, HDC, RECT, INT, INT, SHORT )<br />
page.DrawEx(0, 0, rect, 0, 0, (short)dZoomFactor);<br />

Then it renders the image perfectly in the top corner of the desktop window without any problems but when I create a window and pass the hwnd and DC (Tried GetDC and GetWindowDC), I get nothing.

My eventual aim is to render the page to a bitmap and save as a graphic file.

Any pointers in the right direction?

Thanks,
Dan

Hope I understood your question

<br />
HDC hdc=CreateCompatibleDC(::GetDC(this->m_hWnd));<br />
HBITMAP hbit=CreateCompatibleBitmap(GetDC()->m_hDC,800,600);<br />
	hbit=(HBITMAP)SelectObject(hdc,hbit);<br />
	hbit=(HBITMAP)LoadImage(AfxGetInstanceHandle(),"d:\\error.bmp",IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE|LR_CREATEDIBSECTION);<br />
<br />
SelectObject(hdc,hbit);<br />
BitBlt(GetDC()->m_hDC,0,0,800,600,hdc,0,0,SRCCOPY);<br />
<br />

Good. I'm just in time. This is C file handling code, you should never use it. Instead use ifstream and ofstream.

Is it possible to automate Outlook Express such that I can create a message with
- a recipient
- a subject
- and an attachment

even if Outlook Express is not the default mail client? I am aware of MAPI but, would love to have something that can work with Outlook Express alone and Outlook alone.

Thanks

hi! thanks for the answer.

i already saw this article and while it does create messages, it doesnt seem to do what i want.

What I need is to create a message with an attachment, then display that message window. That article doesnt seem to handle this but just processes the messages in the OE Store itself. Or am I missing something?

I think you are design the Toolbar and you don't want some button's

Simply drag the buttons from toolbar and drop any where... Smile | :)

hope i think right way...

Get the Handle of the button and use

ShowWindow(SW_HIDE);

Open the resource editor in your application and select Toolbar entry from the window that is displayed.
From there select IDR_TOOLBAR and open it.
Just click on the button you don't need on the tool bar and drag it to any empty space on the window.

That is all...

Somethings seem HARD to do, until we know how to do them.

I remember that some time ago, I needed to do the same for my app.
What I did was retrieving the CToolbarCtrl class (through GetToolbarCtrl[^]) and then disabling the button with EnableButton[^].

I remember there was some issue because the toolbar was not properly refreshed (you had to move it first and then it displayed correctly). I solved this issue but I don't remember exactly how (I think by resizing the toolbar by code).

I'm not getting hide button function neither in Visual Studio 2003 nor Visual Studio 6

So i think this will work fine.
m_wndToolBar.SendMessage(TB_HIDEBUTTON, nIndex, MAKELPARAM(bEnable, 0));

It's a member function of CToolBarCtrl and not of CToolBar.

You can derive the class from CStatic and override the MouseOver and MouseLeave Messages.
