You may try getting the current accelerator handle (e.g., m_hAccelTable in a CFrameWnd) and:
1 - Use CopyAcceleratorTable to obtain the current table into an array of ACCEL structures.
2 - Add more ACCEL structures to the array.
3 - Create a new table from the array using CreateAcceleratorTable
4 - Changing the current accelerator to the new one.
5 - Destroy the old accelerator using DestroyAcceleratorTable
It's just a suggestion. Never tried it.
An alternative would be to create a separate table in a derived window and use it in your override for PreTranslateMessage:
BOOL CYourWindow::PreTranslateMessage(MSG* pMsg)
{
if (m_hAccel != NULL && TranslateAccelerator(m_hWnd, m_hAccel, pMsg))
return TRUE;
return CYourWindowBase::PreTranslateMessage(pMsg);
}
The above could be done in a class derived from CWinApp too.
Hope that helps,

Hello,
How can I get unicode build?
I got these two errors after my trying.
C:\haranadh\abc.cpp(185) : error C2664: 'lstrcpyW' : cannot convert parameter 1 from 'char [32]' to 'unsigned short *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
C:\haranadh\abc.cpp(187) : error C2665: 'AfxMessageBox' : none of the 2 overloads can convert parameter 1 from type 'char [32]'
Error executing cl.exe.
abc.exe - 2 error(s), 0 warning(s)
My code is as follows-
----------------------
struct ABCAAA
{
UINT cbSize;
DWORD dwMask;
DWORD dwEffects;
LONG yHeight;
LONG yOffset;
COLORREF crTextColor;
BYTE bCharSet;
BYTE bPitchAndFamily;
char szFaceName[32];
};
void CAbcDlg::OnMyButton()
{
ABCAAA cf;
lstrcpy(cf.szFaceName,_T("Wingdings 3"));
AfxMessageBox(cf.szFaceName);
}
-----
Here I changed some settings of vc++ to build my project in Unicode build.
1)I added in Project Settings->Link->Object/Librirary Modules-> version.lib Winmm.lib
2)Project Settings->C/C++->Preprocessor Definitions->WIN32,NDEBUG,_WINDOWS,_AFXDLL,_MBCS,UNICODE
-----
but I got errors. Previously before changes It works fine.
How can I get unicode build?
Tox, Alok or Anyone Please Help me.

The error message is telling you exactly what's wrong. lstrcpyW() (the Unicode version of lstrcpy()) expects a unsigned short* (more commonly expressed as wchar_t* or LPWSTR) as the first parameter, but you're passing a char array. You probably want szFaceName to be a TCHAR array.

Actually This is I am using as testing program.
But the structure in my actual program is predefined.
that is
typedef struct _charformat
{
UINT cbSize;
DWORD dwMask;
DWORD dwEffects;
LONG yHeight;
LONG yOffset;
COLORREF crTextColor;
BYTE bCharSet;
BYTE bPitchAndFamily;
char szFaceName[LF_FACESIZE];
} CHARFORMATA;
I am using an instance for that typedef.
Thanks for reply.

-change char szFaceName[32] to TCHAR szFaceName[32];;
|
|
|
|
|
I know that. Please check my previous reply.
That was predefined. Just here I wrote sample program.
Any way. Thanks for your reply.

If you want to write code that can be compiled both in MBCS and Unicode you need to:
- Define all your char arrays as TCHAR arrays (e.g., TCHAR szFaceName[32])
- Write all char and string literals using _T macro (e.g., _T("Wingdings 3"))
Additionally, for the Unicode build, you need to:
- Define both UNICODE and _UNICODE
- Remove the define for MBCS
- Set in the linker settings wWinMainCRTStartup as the entry point
That being said, the struct ABCAAA is actually the CHARFORMAT structure, right? Take a look at richedit.h in the VS include files. You'll see a CHARFORMATA (defining szFaceName as a char[]), and a CHARFORMATW (defining szFaceName as a WCHAR[]). Then, you'll see CHARFORMAT defined as follows:
#if (_RICHEDIT_VER >= 0x0200)
#ifdef UNICODE
#define CHARFORMAT CHARFORMATW
#else
#define CHARFORMAT CHARFORMATA
#endif // UNICODE
#else
#define CHARFORMAT CHARFORMATA
#endif // _RICHEDIT_VER >= 0x0200
So, it seems that CHARFORMATA is used even for Unicode builds, unless you also define _RICHEDIT_VER to 0x200 or more. See the following link for info about Rich Edit controls and their versions:
About Rich Edit Controls[^]
Then, if you are going to target 1.0 version, you'll keep using the CHARFORMATA struct, so your sample code should be written as follows:
void CAbcDlg::OnMyButton()
{
CHARFORMAT cf;
int nMaxNameLen = (sizeof(cf.szFaceName)/sizeof(cf.szFaceName[0]))-1;
strncpy(cf.szFaceName, "Wingdings 3", nMaxNameLen);
cf.szFaceName[nMaxNameLen] = '\0';
AfxMessageBox(A2T(cf.szFaceName));
}
This code should work in either MBCS or Unicode builds, for RichEdit version 1.0.
For RichEdit version 2.0 and higher, the code should be:
void CAbcDlg::OnMyButton()
{
CHARFORMAT cf;
int nMaxNameLen = (sizeof(cf.szFaceName)/sizeof(cf.szFaceName[0]))-1;
lstrcpyn(cf.szFaceName, _T("Wingdings 3"), nMaxNameLen);
cf.szFaceName[nMaxNameLen] = _T('\0');
AfxMessageBox(cf.szFaceName);
}
and that should again work for either Unicode or MBCS builds.
Hope that helps,

i am getting error in following code please help
see the function below
i get date as "Sep-05-2005" which i initially read in smonth
after that take from it smonth as Sep and using switch nmonth as 9
now after taking month and removing it from string -05-2005 is left then
comes day
nday=05
now 05-2005 is left
but when 05 is removed instead of -2005 only -20 is left
this error occurs when first time this function is called on exit
for 2, 3 or ___ no error occurs we get complete -2005
i find this in debug mode
BOOL CXmlData::FnCheckForValidDates(CString szEndDate)
{
//Get Current date
CTime TodayDate=CTime::GetCurrentTime();
int nYear,nMonth,nDay;
CString sMonth;
//date format MM-DD-YYYY
//Extract Month
sMonth=(szEndDate.Left(szEndDate.Find('-')));
//remove the month from String
szEndDate.Replace(szEndDate.Left(szEndDate.Find('-')),""); //-05-2005
//Replace Extra '-'
szEndDate.TrimLeft('-');
//code to get int month from string smonth
if(sMonth == "Jan" )
{
nMonth=1;
}
else if(sMonth == "Feb" )
{
nMonth=2;
}
else if(sMonth == "Mar" )
{
nMonth=3;
}
else if(sMonth == "Apr" )
{
nMonth=4;

}
else if(sMonth== "Dec")
{
nMonth=12;
}
//Extract Day
nDay=_ttoi(szEndDate.Left(szEndDate.Find('-')));
//remove the day from String//05-2005
szEndDate.Replace(szEndDate.Left(szEndDate.Find('-')),""); but here -20 is left
//Replace Extra '-'
szEndDate.TrimLeft('-');
//Extract year
nYear=_ttoi(szEndDate);

Because there are two 05 in the string

In programming world ppl do not go by their reputation of a good person in codeproject, If s/he writes bad code it means s/he writes bad code plus the ppl in codeproject dont take programming mistakes too personally.
Your comments probably help the dev to understand his mistake.

Hello everybody,
Does anybody know how I can use the method ExecWB of the WebBrowser control for opening a file on the local machine:
ExecWB(OLECMDID_OPEN, OLECMDEXECOPT_DODEFAULT, ?, ?);
I don't know the use of parameters 3 and 4.
I Also don't want to use Navigate method because of the download prompting.
thanks in advance
Roozbeh.

I wanna to know about this syntax
istream& getline(char *buffer, int length, char terminal_char);
& operator before getline ,what it represent?
Or sometime instead of & there is * also.
What it represent?

hum, i think you need some basic notions about C++.
in such declaration syntax, operator & represent the declaration of a reference, and operator * represent the declaration of a pointer...
in you example, getline get as paramater a pointer to char (buffer), an int (length) and a char (terminal_char). it returns then a reference to an istream instance.

You have to notify the Parent by sending Some Sort of Custom Window Messages! look for WM_APP and WM_USER messages in your locla copy of MSDN

Please choose the Technical Support command on the Visual C++ <br />

I have checked this error number in MSDN,but I can't solve this problem.
So can anybody here do me a favor?
Appreciate.
