How to change a single toolbar icon at runtime?

[madmax0001]

Hello, I have a toolbar with several icons in it and there is one icon that I must change at runtime. How can I manage this? I have tried someting like this, but the code crashes...

CToolBarCtrl& tb = m\_wndToolBar.GetToolBarCtrl();
int iButtonCount = tb.GetButtonCount();

CDC dcMemToolbar; 
CDC dcMemSrc;
CBitmap SrcBmp;
CBitmap NewBmp;
CBitmap\* pOldSrcBmp = NULL;
CDC\* pDc = GetDC();
dcMemToolbar.CreateCompatibleDC(pDc);
dcMemSrc.CreateCompatibleDC(pDc);

SrcBmp.LoadBitmap(IDB\_TOOLBAR);
pOldSrcBmp = dcMemSrc.SelectObject(&SrcBmp);
dcMemToolbar.BitBlt(0, 0, iButtonCount\*16, 16, &dcMemSrc, 0, 0, SRCCOPY);	

NewBmp.LoadBitmap(IDB\_INVALID\_ICON);
dcMemSrc.SelectObject(&NewBmp);
dcMemToolbar.BitBlt(0, 0, 16, 16, &dcMemSrc, 0, 0, SRCCOPY);	

dcMemSrc.SelectObject(pOldSrcBmp);

m\_wndToolBar.SetBitmap(SrcBmp);

Thank you

Better to handle using CImageList it will be easy and convenient. Please try in this way.
