HWND BlurFindWindow(char* BlurTitleText)
{
HWND CurWindowHandle=GetTopWindow(NULL);
do
{
char TitleText[500];
GetWindowText(CurWindowHandle,TitleText,500);
if(!strncmp(TitleText,BlurTitleText,strlen(BlurTitleText)))
return CurWindowHandle;
}while((CurWindowHandle=GetNextWindow(CurWindowHandle,GW_HWNDNEXT))!=NULL);
return NULL;
}
这是一个用C编的函数，你可以参考，都用API，一样

Dim hToolbar As Long
'获的工具条窗口句柄
hToolbar = FindWindowEx(tb.hwnd,0&,"ToolBarWindow32",vbNullString)
你只要把ToolBarWindow32换成word窗体的类就可以了！

FindWindowEx

VB声明
Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As String) As Long
说明
在窗口列表中寻找与指定条件相符的第一个子窗口
返回值
Long，找到的窗口的句柄。如未找到相符窗口，则返回零。会设置GetLastError
参数表
参数类型及说明
hWnd1 Long，在其中查找子的父窗口。如设为零，表示使用桌面窗口（通常说的顶级窗口都被认为是桌面的子窗口，所以也会对它们进行查找）
hWnd2 Long，从这个窗口后开始查找。这样便可利用对FindWindowEx的多次调用找到符合条件的所有子窗口。如设为零，表示从第一个子窗口开始搜索
lpsz1 String，欲搜索的类名。零表示忽略
lpsz2 String，欲搜索的类名。零表示忽略
