With a console application, what would you be adding the menu to?

I think i understand what you are talking about, if you have ever seen the program Edit in MS-DOS you would see a menu, but honestly i dont know how to make one,

Yep, remember it well. What most folks don't know is that the editor was actually qbasic.exe. Edit.com was used to call qbasic.exe and remove any programming-specific menu items.

As far as how to do it, output to a console window using printf(). It's been over a decade since I've done any "console graphics" (e.g., colors, shadows, blocks, 'windows', x/y coordinates) but I'm sure there are still plenty of examples that can be Googled for.

Hi there.

I am currently working on a project to identify users using their typing dynamics. I want to use the intervals
between keystrokes on the keyboard as a user type in their passwords, to identify the users.

I am using Windows XP and Visual Studio C++ 2003 to develope a MFC application project. I want to use a dialog with an edit box
to allow the user to enter his/her username and password.

I cannot process the WM_KEYDOWN and WM_KEYUP messages because when you type in the edit box, the keyboard focus is
on the edit box and not on the dialog.

Will a keyboard hook help me in my mission or will I have to use something else. Something else that is easier to use will also work.

If you could help me I would appreciate it alot.

Thank You.
Ben

If you subclass the edit box, you can pick up the WM_KEYDOWN and WM_KEYUP messages (or indeed any other message), and process them. This article[^] shows how to capture key strokes to create a numeric-only edit box, but it shows how to capture the messages, process them, and then pass them on to the parent window, which is what you'll need to do, I would think.

What does GetLastError() tell you?

Are you sure that the data in the clipboard is CF_UNICODETEXT? Try calling IsClipboardFormatAvailable(CF_UNICODETEXT) before calling GetClipboardData.

So what does GetClipboardData() return? If NULL, what does GetLastError() return?

this is copyed from the class word for word
//Base destructor
CTextFileBase::~CTextFileBase()
{
Close();
}

//Close file
void CTextFileBase::Close()
{
if(IsOpen())
{
#if PEK_TX_TECHLEVEL == 0
m_file.close();
#elif PEK_TX_TECHLEVEL == 1
::CloseHandle(m_hFile);
m_hFile = INVALID_HANDLE_VALUE;
#else
if(m_closeAndDeleteFile)
{
m_file->Close();
}
#endif
}

#if PEK_TX_TECHLEVEL == 2
if(m_closeAndDeleteFile)
{
delete m_file;
m_file = NULL;
}
#endif
}

CTextFileWrite::~CTextFileWrite()
{
Close();
}

//Write and empty buffer
void CTextFileWrite::Flush()
{
#if PEK_TX_TECHLEVEL==0
m_file.write(m_buf, m_buffpos+1);
#elif PEK_TX_TECHLEVEL==1

DWORD nWritten;
if (!::WriteFile(m_hFile, m_buf, m_buffpos+1, &nWritten, NULL))
{
//Something bad has happend! Close file
CTextFileBase::Close();

//Throw exception
throw CTextFileException(GetLastError());
}

#else
m_file->Write(m_buf, m_buffpos+1);
#endif

m_buffpos = -1;
}
when i tryed to debug it had a yellow arrow pointing to this line m_file->Write(m_buf, m_buffpos+1);
PEK_TX_TECHLEVEL = 2 for me incase ya need to know

For starters I would not even begin to debug this. It looks to be way too convulated with all of the preprocessor statements. A well-designed class should be an entity that knows all about itself. When the file-related object is constructed, it should at that point know how it will later be closed.

Have you single-stepped through each statement and noted the value of the variables along the way?

Custom Controls in VC++6

I came across a custom control in an example Project here at The Code Project. I want to use that custom control in another application. How can you use a custom control from one application to another without retyping all the code over again? I tried copying the .cpp and .h files and adding them to my new project but could not get the control classes to be recognized....

Thanks.

You can remake the .dsw file .
The steps is in the following :
1 Delete the old .dsw file in your project's directory
2 goto VC6 ,it will notify you to recreate the dsw file . Then you should select all files int listbox and create it .

Above is all.

Try it

How can you do step 2 if you delete the dsw file? Once I delete this file, I cant open the project in VC6?

Do not believe everything you read on the internet. The file that you are to delete is the .clw (class wizard) file, not the .dsw (project workspace) file.
