It's in MSDN. Here is it's example followed by my example. Make sure you do as it says and either call create with BS_OWNERDRAW or edit the button in the resource workshop and check on OwnerDraw in the properties for the button.

Example

CBitmapButton myButton;

// Create the bitmap button (must include the BS_OWNERDRAW style).
myButton.Create(NULL, WS_CHILD|WS_VISIBLE|BS_OWNERDRAW, 
   CRect(10,10,100,100), pParentWnd, 1);

// Load the bitmaps for this button.
myButton.LoadBitmaps(IDB_UP, IDB_DOWN, IDB_FOCUS, IDB_DISABLE);

I put this in the header file.

CBitmapButton btnStop;
CBitmapButton btnMonitor;

Then in the .cpp's OnCreate() function....

// now load the bitmaps for the CBitmapButton items
if (!m_wndToolBar.btnStop.LoadBitmaps(_T("StopUp"), _T("StopDown"), _T("StopFocus"), _T("StopDown")) ||
    !m_wndToolBar.btnMonitor.LoadBitmaps(IDB_MONUP, IDB_MONDOWN, IDB_MONFOCUS, IDB_MONDOWN) )
{
    TRACE0("Failed to load bitmaps for buttons\n");
    AfxThrowResourceException();
}

If you want only to get a bitmap into the button CBitmapButton is Ok, but if you want more functionality (flat buttons, changing images depending on the mouse cursor...) without effort take a look at Davide Calabro's CButtonST, it's easy to use and will give you the possibility to use buttons as if you where programming in Delphi or VB (setting properties)...

NOTE1:
I'm novice too and it works fine for me...

NOTE2:
I'm new speaking english too...

NOTE3:
you can find CButtonSt and some other classes at codeproject in the button control related web page.

Best regards..

Hey all. I have run into a problem with the MessageBox command. I need the MessageBox to close as soon as a keyboard event occurs, but have yet to find an efficient way to do it. My project is a multiple document MFC program done under Visual C++ 6. Any help you can give would be cool.

Replace MessageBox with modal MFC dialog and override PreTranslateMessage.

I had done something similar to this earlier and it kind of worked but it continued executing the current function even with the modal dialog open. Before I try this method, I was wondering if this would do the same?

Anyone have any idea where the DLGTEMPLATEEX struct is defined??

It's explained and defined in MSDN, but I can't seem to use it in my source, as it isn't defined in any headers that I've included.

It seems to be defined in some of the ATL includes, but as a "local struct used for implementation" (ATLCTL.H).

Now I know that it is used, because if I load a DialogEx into memory and examine it, it's structure conforms to DLGTEMPLATEEX.

Any ideas, short of defining the struct myself where I need it?

TIA,

Pete

Thanks Wolfram, but I actually already had the structure, I just need to know where it's defined, so I don't have to typedef it myself.

I found it in the ATL include, atlhost.h, for class _DialogSplitHelper. Again, it appears to be local. HTHs.

Lock full file?

I'd like to use LockFile()to lock a full file, is this possible?
MSDN doesn't mention how to do this.

Please help Smile | :)

Can you not specify 0 as the starting offset, and the file length as the length to lock?

What happens if the file size is increasing because I append data to the file? Sometimes I want to lock a file and make sure nobody else can modiy or append data to it.

According to MSDN, it is not an error to set the locking range past the end of the file, but I am not sure if that would lock anything you append. To be safe, I think you should re-call LockFile() after you append data, specifying the new file length.

This is just a guess, I have never done this myself Unsure | :~

Can't you just open file using CreateFile and FILE_SHARE_READ flag?

that's not portable. on the other hand, file locking mechanism do exist on various platforms (open file, lock file, do something, close file).

So on these 'various platforms', when you open file, other processes can also open the same file and write at the same time?

that's why you lock files. e.g. you gain the exclusive right to modiy data in a file ata specific time.

I want to write an app that will answer incoming calls and listen for the tones of the caller pressing buttons and do different tasks. Playing a "Press 1 for..." message would be nice also.

My question is where to start. Are there classes/libraries out there that would give me a good base? If anyone has done this or knows where I can start please let me know.

Thanks,

Jack

How to build an Active Document container?

ActiveDocument1-Aug-02 10:20

ActiveDocument

1-Aug-02 10:20

Hey all,

I have an ActiveX control, that was developed using ATL.
Now, I would like to add Active Document containment capabilities to that control, to allow it to host MSHTML.

I've been looking for information in MSDN, but found only little of it - and nothing about ATL - only about MFC.

So -
1. Does ATL have some support for that technology?
2. How difficult would it be to write the required interfaces WITHOUT a tool such as ATL/MFC?
3. Can you refer me to some good examples?

Thanks in advance!

Using a dialog as a control

moredip1-Aug-02 9:54

1-Aug-02 9:54

Hi all,

Anyone know how I would go about embedding a dialog (DVCR) into another dialog (DNewDialog)?

What I want to do is treat it like a CWnd, and use CWnd::Create() in DNewDialog::InitDialog() to add it to the dialog.

I figure I should start by creating an inherited class (DEmbeddedVCR) that inherits from DVCR.

But calling DEmbeddedVCR::Create() always creates a standard dialog, e.g. one you can move around and that has a title bar.

I've tried DEmbeddedVCR::ModifyStyle() with various arguments, but have been unable to make it behave.

Am I going about this totally the wrong way?

TIA,

Pete

Change the style of the embedded in the resource editor to "Child". Then, create it as a modeless dialog.
