Can I safely assume you are talking about a web-camera (webcam)?
The DirectShow examples in DirectX SDK should work with the web-cam. Codes are included.

Hello, My name is jason.
I am trying to write a program that will track the times and the dates that an employee has worked. I know how to hard code it but, it is the gui that i am having a problem with. Here are my main problems. When the program starts i would like a password screen to appear, where the user or the manager enters her/his password. This part I have accomplished, the password screen. I have placed 9 buttons, when the user clicks on the buttons i record or add to a string, and when the user hits okay, i read the finished string and see if there is an employee. My problem is this, I need to have to different windows, one for a manager, and another for a employee. Meaning, if a manager comes along, types his password, i would like a window appearing where he has the option of looking how has clocked in, how many employees are currently working, total hours ans so forth. When a employee comes along, enters his/her password, i would like them to see when they have started, or if they have not punched in, a punch in button, or a punch out button and so forth..
If anyone could help me out, or give me advice on how to create those two different windows and how to interact or how to dynamilcly pop up those two windows depending on who is entering a password, i would be sooooo happy.
you can email me at jdogan@hotmail.com

Sounds like you need some sort of designator that denotes manager vs. non-manager. Are you looking in some sort of file/database to verify the user id and password are correct? If so, just add another field.
You would then need to create two dialog templates: one for managers, and one for non-managers. Then in your code, you could have something like:
DisplayLoginWindow();
if (login_type == manager)
{
CManagerDlg dlg;
dlg.DoModal()
}
else
{
CEmployeeDlg dlg;
dlg.DoModal()
}Make sense?

Thank you both very much, that little bit of code makes a lot of sense, i was thinking of doing just that but did not know if it was possible or smart.. I will look into that and probably do that. Thank you soo much.

Using CSplitterWnd class
I’m trying to learn how to work with CSplitterWnd class.
I create a simple SDI application using MFC Application Wizard.
Classes created are:
CMySDIApp
CMySDIDoc
CMySDIView
CMainFrame
I want to have two different views for my document. For the second view, I add a new class to my project – CMySDIView2 class is derived from CView.
I want to have static splitter with two panes. I override OnCreateClient :
CMainFrame::OnCreateClient(LPCREATESTRUCT /*lpcs*/,
CCreateContext* pContext)
{
// create a splitter with 1 row, 2 columns
if (!m_wndSplitter.CreateStatic(this, 1, 2))
{
TRACE0("Failed to CreateStaticSplitter\n");
return FALSE;
}
// add the first splitter pane - the default view in column 0
if (!m_wndSplitter.CreateView(0, 0,
RUNTIME_CLASS(CMySDIView), CSize(0, 0), pContext))
{
TRACE0("Failed to create first pane\n");
return FALSE;
}
// add the second splitter pane - an input view in column 1
if (!m_wndSplitter.CreateView(0, 1,
RUNTIME_CLASS(CMySDIView2), CSize(0, 0), pContext))
{
TRACE0("Failed to create second pane\n");
return FALSE;
}
return TRUE;
}
When I build the project, I get two errors:
error C2653: 'CMySDIView' : is not a class or namespace name
//RUNTIME_CLASS(CMySDIView), CSize(0, 0), pContext))
error C2653: 'CMySDIView2' : is not a class or namespace name
//RUNTIME_CLASS(CMySDIView2), CSize(0, 0), pContext))
What am I doing wrong?
Thank you for your help!

In order for this to work, both of your view classes must support dynamic creation.
The macro 'DECLARE_DYNCREATE' or 'DECLARE_DYNAMIC' must be found at the start of both classes header files. The parameter for the macro is the class name.
Additionally, a macro 'IMPLEMENT_DYNCREATE' or 'IMPLEMENT_DYNAMIC' must be placed near the top of your implementation file (after the headers, but before function definitions). Parameters for this macro are the class name and the name of the base class.
See the MSDN for information about the differences between these macros.
If all macros are correctly placed in your files, then see if the error is caused by missing header files. Your main frame implementation file must have the header files of both view classes. Otherwise an error is generated.
In addition, the way you create the views is a bit dangerous. A more convinient way is to add the headers into the main frame header file, then create two member variables (either static or dynamic), one of each view class. After this, you can create the views, and specify the splitter window as the parent. Using 'CSplitterWnd::IdFromRowCol' allows you to get the identifier of the pane. When you put this identifier as the id of the newly created view window, the view gets placed into inside the pane.
If you use this technique, however, you must be certain that you destroy the views when your program is closing up. You must first destroy the view windows, then destroy the splitter window, and after this, if you used dynamic variables, you can delete the reserved memory.
There is an article in the works about this method. I'm not sure when it will be out, but I bet in the next few months or so..

When I add header files of both view classes to the main frame implementation file, I get another error:
MySDI\MySDIView.h(17): error C2143: syntax error : missing ';' before '*'
- this one refers to the line: CMySDIDoc* GetDocument() const;
class CMySDIView : public CView
{
DECLARE_DYNCREATE(CMySDIView)
protected: // create from serialization only
CMySDIView();
// Attributes
public:
CMySDIDoc* GetDocument() const;
...............
and there are 3 more errors that are triggerred by the first one:
MySDI\MySDIView.h(17): error C2501: 'CMySDIView::CMySDIDoc' : missing storage-class or type specifiers
MySDI\MySDIView.h(17): error C2501: 'CMySDIView::GetDocument' : missing storage-class or type specifiers
MySDI\MySDIView.h(17): warning C4183: 'GetDocument': missing return type; assumed to be a member function returning 'int'
How can I fix this?
Thank you for you help!!!!

At the top of the MainFrm.cpp, you probably need something like:
#include "MainFrm.h"
#include "MySDIDoc.h"
#include "LeftPaneView.h"
#include "RightPaneView.h"

when I do this, I get the error I described above (please, see it in the third message in this thread)

The compiler is telling you that CMySDIDoc is being referenced before it has been declared.

I added
#include "MySDIDoc.h"
to the MySDIView.h file and it solved the problem.
Thank you!!!

I'm using a CHtmlView control and I want to store the content displayed in the control in a CString object or as a string. How do I go about it?
Thanks in advance,
Vikram.

How? 
I get an error saying GetSource is not a member of this class. And MSDN says GetSource belongs to IErrorInfo.
Am I completely missing the point?

Alright, I tried it under VS.net 2002 and it works. Would there be a way of getting the text alone, without the tags?
I could strip out the tags, but just want to know if there's an easier way out.

If you decide to strip the tags, there's a removeHtml() API in this[^] article that you may want to use.

You can call GetHtmlDocument(), which returns a pointer to a IHTMLDocument.

Hi, I am trying to write/read a large vector of vector of doubles to comma delimited text file using std::ofstream. The problem is that it doesn't seem to be very fast, taking a few minutes at a time.
The matrix to be written/read is of the size N x M, where N is approx. 2,000 and M is between 1,000 and 40,000. That means a file size of up to approx. 800Mb for M == 40,000.
Should I consider serialization as something that might be faster?
At the moment I am not doing anything complicated, below is my code for writing the 'spreads' matrix to file (removed conditional error checks, etc):
ofstream write_file;
write_file.open(fileName.c_str(), ios_base::out | ios_base::trunc );
int numRows = spreads.size();
int numCols = spreads[0].size();
for (int row = 0; row < numRows; row++)
{
for (int col = 0; col < numCols; col++)
{
write_file << "," << spreads[row][col];
}
write_file << endl;
}
write_file.close();
When reading it in I do much the same thing, reading in the file line by line and using a split string algorithm to extract each row of doubles, building up the matrix of doubles.
The CPU is at 100% at all times when this is run, so it's not slow file I/O that's the problem.
Any suggestions would be appreciated.
Thanks,
Christopher

One solution is the STL's copy() algorithm and ostream_iterator.
