Toolbar:undeclared identifier:BTNS_BUTTON,I_IMAGENONE,MAX_LEN
Hello,
OS: Win2000 , Compiler:MSCV 6.0
I copy source code from MSDN:Using Toolbar...:
Code:
// 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 :
Code:
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! :)
