How can I get a HBITMAP handle from a CImageList Object?

Have you seen CImageList::GetImageInfo ?

Thank you very much

See m_ImageList->GetImageInfo(...); -----------------------And----------- You can use From ExtractIcon(index) for get a hicon of list and draw this icon to a dc and save this dc to a bitmap this code is an idea maybe its not good but if you want to checking this code its working. CImageList* m_ImageList; CBitmap Bmp; m_ImageList=new CImageList(); m_ImageList->Create(32,32, ILC_COLORDDB,0,0); Bmp.LoadBitmap(IDB_BITMAP1); m_ImageList->Add(&Bmp,RGB(100,105,0)); m_ImageList->Add(&Bmp,RGB(100,105,0)); CDC dc; CBitmap p; CImage m; dc.CreateCompatibleDC(GetDC()); p.CreateCompatibleBitmap(GetDC(),32,32); dc.SelectObject(p); for (int i=0;i < m_ImageList->GetImageCount();i++) { dc.DrawIcon(0, 0, m_ImageList->ExtractIcon(i)); //dc.SelectObject(p); m.Attach(p); m.Save("c:\\0.bmp"); m.Detach(); } //now free resources...

Thank you very much. but there is still a problem. the bmp that saved have a black background. how could I change the back colour into what ever I want?? And It is much better that you don't use CxImage. -- modified at 7:57 Friday 25th August, 2006

You mean to say, you want to change BMP, is it?

Yes,change the backgroud colour. change black background into red,for example.

DrawIcon(you need to calculate x from icons in your listimage,0,m_ImageList->ExtractIcon(i))

I'm not sure, if its possible.

Its possible(he needs a little work for it)

void CSaveBmpToFileDlg::GetImageFromList(CImageList *lstImages, CBitmap* destBitmap)
{

CImageList tmpList;
tmpList.Create(lstImages);


IMAGEINFO lastImage;
tmpList.GetImageInfo(0,&lastImage);

CDC dcMem; 

dcMem.CreateCompatibleDC(GetWindowDC()); 

CRect rect (lastImage.rcImage);

destBitmap->CreateCompatibleBitmap (this->GetWindowDC(), 
	rect.Width () \* tmpList.GetImageCount(), rect.Height ());

CBitmap\* pBmpOld = dcMem.SelectObject (destBitmap);

for (int i=0;i

I got this code. the bmp itself was nice.but still,the back was black:(

Hamid Taebi

In this example we have a 32x32 and if you calculate x for x for draw function then your problem solve but if you want to get x& y from icons in CImageList see ImageList_GetIconSize(yourlist,x,y) and then insert x to current position in DrawIcon if you test this code and your problem is slove i glad but if you have previous error reply to me:)

Thank you sir. I tried to do as what you have said. the bmp file was saved correctly. but the background was still black. I want to change the background into RGB(255,0,255). How could I do so? Thank you very much.

Hamid Taebi

for black background dc.DrawIcon(x/*32*/, 0, m_ImageList->ExtractIcon(i)); i used 32x32 for your icons you need to calculate x and y for change background you can use from: you need to two CDC objects one for draw icon and another for draw previous dc in new dc(for change color) 1-create two dc(dc1,dc2)and create two bitmap 2-in dc1 you draw icon 3-in dc2 you need to set color for bitmap and draw dc1 to dc2 4-then save this dc it seems that its hard but when you start to this work its not hard also you can find examples for this purpose in bitmap i think i see examples for example you need to draw many pictures to a picture if you write this program then its very helpful in your programming.

You can try this HBRUSH hbr; hbr = ::CreateSolidBrush(RGB(255,255,255)); //this will draw white BackGround before drawing ICON onto it. DrawIconEx(hDC,0,0,hIcon,0,0,0,hbr,DI_DEFAULTSIZE); Matt
