Hi

The new version is below same applies, we are creating the object using CreateCompatibleBitmap which according to microsoft doesn't need to have it's object selected, however I did try this and still same black square, I have sent the project to you via priority support to show you the problem.

Thanks for the help

Terry

HBITMAP hBitmap = (HBITMAP)::LoadImage( NULL, "c:\\1.bmp", IMAGE_BITMAP, 0, 0, LR_CREATEDIBSECTION | LR_LOADFROMFILE );

if ( hBitmap == NULL ) return;

CDC *pSourceDC = new CDC;

CDC *pDestinationDC = new CDC;

CBitmap *pSourceBitmap = new CBitmap;

pSourceBitmap->Attach( hBitmap );

pSourceDC->CreateCompatibleDC( NULL );

CBitmap *pOldSourceBitmap = pSourceDC->SelectObject( pSourceBitmap );

pDestinationDC->CreateCompatibleDC( NULL );

CBitmap *pDestinationBitmap = new CBitmap;

pDestinationBitmap->CreateCompatibleBitmap( pSourceDC, 48, 48 );

CBitmap *pOldDestinationBitmap = pSourceDC->SelectObject( pDestinationBitmap );

pDestinationDC->StretchBlt( 0, 0, 48, 48, pSourceDC, 0, 0, 300, 300, SRCCOPY );

pSourceDC->SelectObject( pOldSourceBitmap);

delete pSourceDC;

m_ImageList.Add( pDestinationBitmap, m_crMaskColour );

pDestinationDC->SelectObject( pOldDestinationBitmap );

delete pDestinationDC;

delete pDestinationBitmap;

delete pSourceBitmap;

Hi,

You didn't select pDestinationBitmap to pDestinationDC...

You don't need to much new/delete create them in heap:

CDC dcSrc;

dcSrc.CreateCompatibleDC(NULL)

etc

Hi

Ok that works fine until we then create a 2nd DC with a compatible bitmap so we can then stretchblt to other DC to create our item (thumbnail), the code is as follows:

HBITMAP hBitmap = (HBITMAP)::LoadImage( NULL, "c:\\1.bmp", IMAGE_BITMAP, 0, 0, LR_CREATEDIBSECTION | LR_LOADFROMFILE );

if ( hBitmap == NULL ) return;

CDC *pSourceDC = new CDC;

CDC *pDestinationDC = new CDC;

CBitmap *pSourceBitmap = new CBitmap;

pSourceBitmap->Attach( hBitmap );

pSourceDC->CreateCompatibleDC( NULL );

CBitmap *pOldSourceBitmap = pSourceDC->SelectObject( pSourceBitmap );

pDestinationDC->CreateCompatibleDC( NULL );

CBitmap *pDestinationBitmap = new CBitmap;

pDestinationBitmap->CreateCompatibleBitmap( pSourceDC, 48, 48 );

pDestinationDC->StretchBlt( 0, 0, 48, 48, pSourceDC, 0, 0, 300, 300, SRCCOPY );

pSourceDC->SelectObject( pOldSourceBitmap);

delete pSourceDC;

m_ImageList.Add( pDestinationBitmap, m_crMaskColour );

delete pDestinationDC;

delete pDestinationBitmap;

delete pSourceBitmap;

Thanks for help, it is much appreciated.

Hi,

Don't think problem in CreatecompatibleDC line - think ptoblem that you call SelectObject and didn't restore context back.

try

CBitmap* pOldBitmap = pDC->SelectObject( pBitmap );

// Make some work

pDC->SelectObject( pOldBitmap);

delete pDC;

m_ImageList.Add( pBitmap, m_crMaskColour );

delete pBitmap;

The problem seems to be that we are passing NULL when we create compatible DC, and even thou we are attaching the bitmap it is not setting up this DC correctly. Any ideas on what else we can pass ?

Any help appreciated, even willing to pay somebody to help us fix this as urgent for a projecct.

Hi

We load our images from disk then we resize them or add text etc. to each one, so we may need more images, but first we have to create a compatible DC so we can edit the images or add text.

This is the problem :(

Thanks

Terry

The problem is we need to use the DC because we want to edit the bitmap, eg. Resize or add text before it is added to gallery control

Thanks

Terry

ps: You don't need these lines to convert hbitmap to CBitmap:

CBitmap *pBitmap = new CBitmap;

pBitmap->Attach( hBitmap );

CDC *pDC = new CDC;

pDC->CreateCompatibleDC( NULL ); // this line seems to make it fail

pDC->SelectObject( pBitmap );

just need these:

HBITMAP hBitmap = (HBITMAP)::LoadImage( NULL, "c:\\1.bmp", IMAGE_BITMAP, 0, 0, LR_CREATEDIBSECTION | LR_LOADFROMFILE );

CBitmap bmp;

bmp.Attach(hBitmap);

Hello,

Instead of converting bitmap to imagelist, you can set bitmap directly -

BOOL SetIcons(CBitmap& bmpIcons, UINT* pCommands, int nCount, CSize szIcon, XTPImageState imageState = xtpImageNormal, BOOL bAlpha = FALSE)

We are having a problem with the following code as we want to generate gallery control items on the fly, however once we add the CreateCompatibleDC( NULL ) section it only shows a black square for each gallery control item

Any help would be much appreciated as this code works fine in OnPaint handlers etc.

--------

m_ImageList.Create( m_nWidth, m_nHeight, ILC_COLOR32 | ILC_MASK, 0, 1 );

HBITMAP hBitmap = (HBITMAP)::LoadImage( NULL, "c:\\1.bmp", IMAGE_BITMAP, 0, 0, LR_CREATEDIBSECTION | LR_LOADFROMFILE );

if ( hBitmap == NULL ) return;

CBitmap *pBitmap = new CBitmap;

pBitmap->Attach( hBitmap );

CDC *pDC = new CDC;

pDC->CreateCompatibleDC( NULL ); // this line seems to make it fail

pDC->SelectObject( pBitmap );

m_ImageList.Add( pBitmap, m_crMaskColour );

--------

Thanks for any help, much appreciated.

Terry
