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.

How about InsertMenuItem() api

I want to work on images in VC++. Is it possible to load bmp,jpg,png and tiff image types? Unsure | :~

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

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.

MFC SDI help

30-Sep-05 7:34

Quick question: I want to treat an SDI sort of like a dialog box -- I'm going to want to put some graphical buttons on the screen, some edit boxes, etc. But I want more flexibility with what I draw on the window than I get in a dialog app, plus I think I want to use the menu bar... maybe eventually a toolbar. So I'd like to do this with and SDI app. I asked a friend I work with if he knows how to do that, and he said he remembered seeing exactly what I was looking for on The Code Project, but couldn't find it in all the articles.

Okay, so the question wasn't so quick, but the answer should be. Could anyone provide a link to the article I need based on the description I gave above?

It sounds like you need to use CFormView.
