更改对话框图标

您需要找到您感兴趣的对话框的对话过程,并在 WM_INITDIALOG 消息处理程序(如果它不存在,则需要添加它)使用 WM_SETICON 要设置图标:

// hIcon is your icon handle
SendMessage(hDlg, WM_SETICON, ICON_SMALL, (LPARAM)hIcon);
SendMessage(hDlg, WM_SETICON, ICON_BIG, (LPARAM)hIcon);

如果LoadIcon是MFC,也可以搜索它(例如CDialog)

希望对你有帮助

BOOL sendWndIconToTaskbar(HWND hWnd,HICON hIcon) 
{ 
    BOOL ret = TRUE; 
    ASSERT(hWnd); 
    if(!::IsWindow(hWnd)) 
        return FALSE; 
    CWnd* pWnd; 
    pWnd = pWnd->FromHandle(hWnd); 
    ASSERT(pWnd); 
    if(!pWnd) 
        return FALSE; 
    if(pWnd->GetParent())
    {
        if(::SetWindowLong(hWnd,GWL_HWNDPARENT,NULL) == 0) 
            return FALSE; 
    }


    if(!(pWnd->ModifyStyle(NULL,WS_OVERLAPPEDWINDOW))) 
        ret = FALSE; 
    pWnd->SetIcon(hIcon,TRUE); 
    pWnd->SetIcon(hIcon,FALSE); 

    return ret; 
} 

HICON hIconSm = (HICON)LoadImage(NULL, "default.ico", IMAGE_ICON, 32, 32, LR_LOADFROMFILE);
sendWndIconToTaskbar(pOcxDlg->m_hWnd,hIconSm);
