I've got an About CDialog that has 2 buttons on it (OK, Release Notes). When I click the 'X' to close the dialog it acts as though I clicked on the Release Notes button. Confused | :confused:

I can close the dialog by clicking OK, any ideas on getting it to close on 'X'?

Make sure the ID of the 'Release Notes' buttons is not IDCANCEL.

Ah, good thought, but no it's ID_RELEASE.

So when the "X" is clicked, the handler function for the "Release Notes" button is getting called. Yes?

What is the value of ID_RELEASE?

What does the About dialog's message map look like?

Change it to 102 and it'll work! Wink | ;)

Here's the reason: IDCANCEL has a value of 2.

I changed it, but had the same issue. I ended out renaming the ID, deleting the old ID and creating a new button with the old ID name. It got a new random ID value, and all's good.

Thanks for your help, David.

Actually, there not random at all. They are controlled by the _APS_NEXT_CONTROL_VALUE macro at the bottom of the project's resource.h file.

Hi gurus,

I'd like to know how to
1) save the list of all open documents in an MDI before closing the application and the last active document
1) reload the documents when the MDI application starts.

Thanks Smile | :)

Best regards.

CBitmap to BMP file

Hi everyone!

I needed to save picture from CBitmap object to BMP file. I have made this method:

BOOL SaveBMPImage( LPCTSTR sBMPFile, CBitmap& bitmap )
{
BITMAP bmap;
bitmap.GetBitmap(&bmap);

BITMAPINFOHEADER bmih;
bmih.biSize = sizeof(BITMAPINFOHEADER);
bmih.biWidth = bmap.bmWidth;
bmih.biHeight = bmap.bmHeight;
bmih.biPlanes = 1;
bmih.biBitCount = 32;
bmih.biCompression = BI_RGB;
bmih.biSizeImage = 0;
bmih.biXPelsPerMeter = 0;
bmih.biYPelsPerMeter = 0;
bmih.biClrUsed = 0;
bmih.biClrImportant = 0;

BITMAPFILEHEADER bmfh;
bmfh.bfType = 0x4d42; // 'BM' WINDOWS_BITMAP_SIGNATURE
bmfh.bfSize = bmih.biSize + bmih.biSizeImage + bmih.biClrUsed * sizeof(RGBQUAD) + 14 ;
bmfh.bfReserved1 = bmfh.bfReserved2 = 0;
bmfh.bfOffBits = 14 + bmih.biSize + bmih.biClrUsed * sizeof(RGBQUAD);

CFile file;
if( !file.Open(sBMPFile , CFile::modeWrite | CFile::modeCreate ) )
return FALSE;

// Write the file header
file.Write( &bmfh , min(14,sizeof(BITMAPFILEHEADER)) );
// Write the DIB header
file.Write( &bmih , bmih.biSize);

long velkost;
velkost = bmap.bmWidthBytes * bmap.bmHeight;
// otocenie obrazka (je dolu hlavou)
CDC dc;
dc.CreateCompatibleDC(NULL);
dc.SelectObject(&bitmap);
long i,j;
COLORREF farba;
for( j=0 ; j

Which View subclass to use?

So what is it that does not work? Have you stepped through the code to see what values are different between two machines? Do you have error-checking in place? How do the two .bmp files differ?

I am not sure about the value that the GetBitmapBits() returns, but all others are the same. In wiever looks the picture as I am looking through a film negative (just violet,red and black colours) and the picture is there twice.

If you have any idea or if you have any method for saving a CBitmap to BMP file that works everywhere and you'll send it to me, I will be very thankful.

Thank you very much

are you sure your bitmap from GetBitmapBits is actually 32 bits?

Hi,

I have to code a SDI MFC application as below:

 ----------------------
| This is heading      |
|                      |
| 1. some text         |
| 2. Some text         |
| 3. Some text         |
| 4. Some text         |
|                      |
 ----------------------

The "This is heading" part should not be scrollabe and below that part i.e from "1. Some text ......." should be scrollable.
Please tell me which CView subclass should I use.
Send me sample code / any articles.

Thanks & Regards,
Neeraj

You could use a CFormView derived class that has a static header and a scrollable window below it. I do not have any examples but they are very easy to use. Just like designing a dialog box.
