Re: Copy into a bitmap

Thanks for sticking with me on this one Smile | :)

In SetButtonIcon I have the following to create a copy of the bitmap:

IMAGEINFO imgInfo;
m_imageList.GetImageInfo (0, &imgInfo);
m_hbmpDisabled = (HBITMAP)::CopyImage (imgInfo.hbmImage, IMAGE_BITMAP, 
    m_nImageWidth, m_nImageHeight, LR_COPYDELETEORG);

Then in DrawItem I use the following to draw it as a disabled image:

pDC->DrawState (CPoint (3, 3), CSize (m_nImageWidth, m_nImageHeight),
    m_hbmpDisabled, DST_BITMAP | DSS_DISABLED);

Unfortunately this just draws a grey square, rather than the disabled image. The SetButtonBitmap function uses a similar process, but uses CreateMappedBitmap to map the mask colour to white. This bitmap is then copied into m_hbmpDisabled using ::CopyImage.

Presumably this is the step that is missing in SetButtonIcon, but how can I use CreateMappedBitmap without a bitmap resource id?

So SetButtonBitmap works OK? If yes, you should try to pass DST_ICON flag to DrawState inside SetButtonIcon. No CopyImage call would be required in this case.

Thanks for your email yesterday.

Finally I've got it cracked Smile | :)

I add the bitmap ot icon into the image list in SetButtonBitmap or SetButtonIcon respectively, and then in DrawItem I use ExtractIcon and treat any image in the image list, regardless of source, as an icon. That way I don't need to worry about a copy of the bitmap or anything. This opens the door to multiple images Smile | :)

I feel like I've broken the back of this project. Hopefully before long I'll publish the article and code.

Thanks for your help.

You could try the 'alternate data streams' feature. Check KB article Q105763 for details.

CEdit and Enter

Hello,

I'm working on a Dialogbased Windows CE application. The application communicates with a device. It's the intention that when I type in some digits in an EditBox and press Enter, the string of digits will be send to the device. When I use an OnChangeEDit Event, every time I type in a digit the data is send. How can I avoid this so it will only send the data when I press Enter?

You should be able to fix it by just adding 'Ws2_32.lib' to your project settings.

OS Interfering with DirectInput?

6-Aug-01 20:06

I'm writing a program using DirecX 8.0 in a Win32 environment. This program takes exclusive control over the screen and aquires the mouse using DirectInput. During the course of the program after a set amount of mouse clicks the pc speaker starts beeping for every movement or click (including the keyboard.) I must state that the program's performance isn't affected by what's going on in the background. I'm thinking that the OS's (Windows 9x) internal buffer is overflowing which is what's producing the beeping but I'm not sure. Is there a way to flush the OS's mouse buffer? Is this the solution to the problem?

Thank You,
