Toolbar:undeclared identifier:BTNS_BUTTON,I_IMAGENONE,MAX_LEN

[Cooker]

Hello,
OS: Win2000 , Compiler:MSCV 6.0
I copy source code from MSDN:Using Toolbar...:

// CreateAToolBar creates a toolbar and adds a set of buttons to it.
// The function returns the handle to the toolbar if successful, 
// or NULL otherwise. 
// hwndParent is the handle to the toolbar's parent window. 
HWND CreateAToolBar(HWND hwndParent) 
{ 
   HWND hwndTB; 
   TBADDBITMAP tbab; 
   TBBUTTON tbb[3]; 
   char szBuf[16]; 
   int iCut, iCopy, iPaste;
   INITCOMMONCONTROLSEX icex;
   HRESULT hr;
   size_t cch;

// Ensure that the common control DLL is loaded. 
   icex.dwSize = sizeof(INITCOMMONCONTROLSEX);
   icex.dwICC  = ICC_BAR_CLASSES;
   InitCommonControlsEx(&icex);

// Create a toolbar. 
   hwndTB = CreateWindowEx(0, TOOLBARCLASSNAME, (LPSTR) NULL, 
        WS_CHILD | CCS_ADJUSTABLE, 0, 0, 0, 0, hwndParent, 
        (HMENU) ID_TOOLBAR, g_hinst, NULL); 

// Send the TB_BUTTONSTRUCTSIZE message, which is required for 
// backward compatibility. 
   SendMessage(hwndTB, TB_BUTTONSTRUCTSIZE, (WPARAM) sizeof(TBBUTTON), 0); 

// Add the button strings to the toolbar's internal string list. 
   LoadString(g_hinst, IDS_CUT, szBuf, MAX_LEN-1); 
//Save room for second terminating null character.
   hr = StringCchLength(szBuf, MAX_LEN, &cch);
   if(SUCCEEDED(hr))
   {
   szBuf[cch + 2] = 0;  //Double-null terminate.
   }
   else
   {
   // TODO: Write error handler.
   } 
   iCut = SendMessage(hwndTB, TB_ADDSTRING, 0, (LPARAM) (LPSTR) szBuf); 
   LoadString(g_hinst, IDS_COPY, szBuf, MAX_LEN-1);  
//Save room for second terminating null character.
   hr = StringCchLength(szBuf, MAX_LEN, &cch);
   if(SUCCEEDED(hr))
   {
   szBuf[cch + 2] = 0;  //Double-null terminate.
   }
   else
   {
   // TODO: Write error handler.
   } 
   iCopy = SendMessage(hwndTB, TB_ADDSTRING, (WPARAM) 0, 
       (LPARAM) (LPSTR) szBuf); 
   LoadString(g_hinst, IDS_PASTE, szBuf, MAX_LEN-1);  
//Save room for second terminating null character.
   hr = StringCchLength(szBuf, MAX_LEN, &cch);
   if(SUCCEEDED(hr))
   {
   szBuf[cch + 2] = 0;  //Double-null terminate.
   }
   else
   {
   // TODO: Write error handler.
   } 
   iPaste = SendMessage(hwndTB, TB_ADDSTRING, (WPARAM) 0, 
        (LPARAM) (LPSTR) szBuf); 
 
// Fill the TBBUTTON array with button information, and add the 
// buttons to the toolbar. The buttons on this toolbar have text 
// but do not have bitmap images. 
   tbb[0].iBitmap = I_IMAGENONE; 
   tbb[0].idCommand = IDS_CUT; 
   tbb[0].fsState = TBSTATE_ENABLED; 
   tbb[0].fsStyle = BTNS_BUTTON; 
   tbb[0].dwData = 0; 
   tbb[0].iString = iCut; 
 
   tbb[1].iBitmap = I_IMAGENONE; 
   tbb[1].idCommand = IDS_COPY; 
   tbb[1].fsState = TBSTATE_ENABLED; 
   tbb[1].fsStyle = BTNS_BUTTON; 
   tbb[1].dwData = 0; 
   tbb[1].iString = iCopy; 

   tbb[2].iBitmap = I_IMAGENONE; 
   tbb[2].idCommand = IDS_PASTE; 
   tbb[2].fsState = TBSTATE_ENABLED; 
   tbb[2].fsStyle = BTNS_BUTTON; 
   tbb[2].dwData = 0; 
   tbb[2].iString = iPaste; 

   SendMessage(hwndTB, TB_ADDBUTTONS, (WPARAM) NUM_BUTTONS, 
        (LPARAM) (LPTBBUTTON) &tbb); 

   SendMessage(hwndTB, TB_AUTOSIZE, 0, 0); 

   ShowWindow(hwndTB, SW_SHOW); 
   return hwndTB; 
}

After compiling the source code,the compiler :

error C2065: 'MAX_LEN' : undeclared identifier
warning C4013: 'StringCchLength' undefined; assuming extern returning int
error C2065: 'I_IMAGENONE' : undeclared identifier
error C2065: 'BTNS_BUTTON' : undeclared identifier

How do I to define the undeclared identifier???
To remove those undeclared idenfitifer and to build:
unresolved external symbol _StringCchLength
What 's wrong?
Could someone help me explain???
Thanks!

I replace BTNS_BUTTON to TBSTYLE_BUTTON,I_IMAGENONE to -1 and define MAX_LEN as 128.
But I don't know how to solve the "unresolved external symbol _StringCchLength".

Add strsafe.lib in your linker settings or #pragma comment(lib,"strsafe")

For those that read this that do not have strsafe.lib, or strsafe.h then download the latest platform SDK.

Excuse me! Where to download the latest platform SDK?
Thanks!

I would have expected a different error if you did not have the SDK already installed. Then again...looking at the headers...that makes sense

Before updating the sdk:

Cannot open include file: 'strsafe.h': No such file or directory
cannot open file "strsafe.lib"

I temporarily replace StringCchLength by strlen.
