BOOL SetWindowPos(const *CWnd pWndInsertAfter, int X, int Y, int cx, int cy, UINT uFlags) is a methode of CWnd class, so when calling it, it positions the object that is an instance of that class.

::SetWindowPos(HWND hWnd, HWND hWndInsertAfter, int X, int Y, int cx, int cy, UINT uFlags) needs a parameter to identify the window to be positioned (hWnd)

this api version of SetWindowPos function.. now to access this function in mfc based application you have to use '::' scope resolution operator...

Adding items to menus

Hi guys and girls. Short question. Does ANYBODY know how to add an item to a Windows standard context menu after subclassing it? I would like to do that with one of the context menus of the system but without tampering with the registry. It's something related to sending some commands to that menu after the WM_INITMENU message.

I have heard of IPicture class that uses OLELoadPicture() through which it is possible to load jpg and bmp, but I don't have any idea whether they work on pixel levels like returning and setting pixel values.

Can u help me out? Confused | :confused:

Since Hook Application/dll run in context of Application, it is hooked so you can use
AfxGetAppName(...) or GetModuleFileName(...) api to get application name

string manipulation question

when is it ok to do pch++ and when should you use CharNext/_tcsinc? I'm guessing pch++ is fine for ansi char* and unicode TCHAR* for english, so do you use CharNext/_tcsinc for programs that will have text in a non-english encoding, a non-western european encoding?
- thanks

Jose Lamas Rios30-Sep-05 17:28

pch++ can be used for WCHAR* or, if you know the string is using a code page in which there are no multi-byte chars (e.g., English, Spanish, French), for char* too.

CharNext or _tcsinc are used when you want to write code that can be used, whithout changes, either for SBCS, MBCS, or Unicode builds. For example, the following code:

_TCHAR buffer[] = _T("This is a test");
int nLen = 0;
for (const _TCHAR* pch = buffer; *pch; pch = _tcsinc(pch))
{
   nLen++;
}

gets expanded as follows:

// SBCS (when neither _MBCS nor _UNICODE are defined)
char buffer[] = "This is a test";
int nLen = 0;
for (const char* pch = buffer; *pch; pch = _strinc(pch))
{
   nLen++;
}

// UNICODE (when _UNICODE is defined)
wchar_t buffer[] = L"This is a test";
int nLen = 0;
for (const wchar_t* pch = buffer; *pch; pch = _wcsinc(pch))
{
   nLen++;
}

// MBCS (when _MBCS is defined)
char buffer[] = "This is a test";
int nLen = 0;
for (const char* pch = buffer; *pch; pch = _mbsinc(pch))
{
   nLen++;
}

good afternoon,

the app crashed with access violation and "scalar deleting destructor". I think it means there was an explicit call to virtual destructor corrupts stack. But I don't really see when did it happen........ here some part of the code that causing the problem..thanks!

bool chrgDlg::charges()
{
...............

if ( !m_bCanceled )
m_dbANI.MoveNext();
}

if (!m_vecBuffer.empty())
{
m_binOutfile.append (&m_vecBuffer[0], m_vecBuffer.size());
m_vecBuffer.clear();
}

if (!m_binOutfile.empty())
m_binOutfile.sort();

return true;
}

I'm trying to add a button that when the user pushes it, the Network Connections window will open. Or if possible the properties of the current connection (i.e. Local Area Connection).

Any suggestions?

I tried searching through the articles and the message board to no avail.

You are trying to start a control panel app, what you can do is launch the app which has the extention .cpl,

I do not remember how to start the .cpl file, but this would be a good hint for searching.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
