FriendFeedUsing 256 color bitmaps in toolbar
Posted
by Kevin Bentley
on August 22nd, 1998
I recently needed to have 256 color toolbars in my app. If you create 256 color bitmaps in devstudio, and try to use them with CToolbar it won't work.
The problem is in the LoadBitmap() member or CToolbar. Appwizard will create the following line in your CMainFrame class:
m_wndToolBar.LoadBitmap(IDR_MAINFRAME)
Here is the fix, just replace the load bitmap call with a call to the control itself:
m_wndToolBar.GetToolBarCtrl().AddBitmap(iNumButtons,IDR_MAINFRAME);
It really is that easy, I found this solution after writing my own toolbar class that used the tool control directly, and 256 color bitmaps worked fine. I couldn't believe it, but it works!

Hi,
The article is superb. But the problem with me is that I have a number of ".ico" files, each containing an icon. Kindly tell me how to put that on a toolbar button.

It can load 256 Colors bitmap ,and you can dispose bitmap backgroud ,RGB (192,192,192 ) is Color Mask .and bitmap backgroud is RGB (192,192,192)
CImageList *pImgList = m_wndToolBar.GetToolBarCtrl().GetImageList();
pImgList->DeleteImageList();
pImgList->Create(48, 48, ILC_COLOR8 | ILC_MASK, 0, 10);
CBitmap ToolBarBm;
ReplyToolBarBm.LoadBitmap (IDB_ToolBar);
pImgList->Add (&ToolBarBm,RGB(192,192,192));
CBitmap DisToolBarBm;
DisToolBarBm.LoadBitmap (IDB_DisaToolBar);
CImageList* pDisaImgList;
pDisaImgList=new CImageList ;
pDisaImgList->Create(48, 48, ILC_COLOR8 | ILC_MASK, 0, 10);
pDisaImgList->Add (&DisToolBarBm,RGB(192,192,192));
m_wndToolBar.GetToolBarCtrl().SetImageList(pImgList);
m_wndToolBar.GetToolBarCtrl().SetDisabledImageList (pDisaImgList);

Bitmaps go black when changing color depth
Posted by Legacy on 09/06/2001 12:00amOriginally posted by: Dan
If you change from 32 bit -> 16 bit color (actually between any two color depths), the bitmaps go black. Does anyone know of a solution for this or is it a bug in the toolbar control?
