Given that you used || instead of |, the second parameter is evaluating to 1, which is the same thing as CFile::modeWrite. That's why the file does not get created.
Also, the CFile::typeText flag is ignored with CFile objects. It's used with derived classes only.

This should be LogFile.Write(fname, fname.GetLength() * sizeof(TCHAR)) instead.

If you are using CString for fname, you should not use sizeof for the length. You should use fname.GetLength().
onwards and upwards...

how can I add this console app. to my project as a class????!!!!

There is no one-to-one correlation between a file/app and class. A class should be thought of as an autonomous object. You will need to go through the application, probably several times, and figure out what parts can be put into their own class. You may end up with one large class (hopefully this won't be the case as large classes are unproductive), or you may end up with dozens of smaller classes.
As a very primitive example, how would you turn the following application into one or more classes:
#include <stdio.h>
void main( void )
{
printf("Hello World\n");
}

david told the most, but you could do this.
is the source is well written, it is probable that its author put his class declaration into a whole header file (h, hpp, hxx, hh), and the implementation into a module file (cpp, cc, cxx).
if so, just import those 2 files into your workspace (VC++6) or project (VC++7 and later)
if he didn't, extract the classe by yourself and paste it into a new file of your own in your solution (but i doubt you'll have to do that).

there are 3 header files
and 2 module files(.cpp)
how can I import these files to my workspace(I'm using VC++ 6)
|
|
|
|

you copy the files into the directory your source files are created (into windows explorer).
then, you go into your workspace (workspace tab), and right click the project item -> add existing files to project... and choose the files you've just copied...
the header will appear in the header folder, and the c files in the source folder...

i think you will need to wrap your value in a class ( or maybe a template of some sort ) with a overriden operator;
something like :
class myValue
{
public:
myValue( int value ) : m_Value( value ) {};
int getValue( return m_Value;};
private:
const int m_Value;
};
or after thinking about it, maybe something like :
const int* pInt = new int(3);

To create a const *, you can put const in two places,
const char *
char * const
You can do both. One says you can't change the memory address the pointer points to, the other says you cannot change it's contents.

While we're on the subject, Christian, what is the difference between these two. (I always get them backwards!)
abc(CString& const );
def(CString const& );

This one is pointless. You can't declare a "const reference" because a reference is already const.
Tom Archer wrote:

This is a reference to a const CString.

What does this one mean?
ghi(const CString&);

It too is a reference to a const CString. In other words, the following are equivalent, just different styles:
const CString &str;
CString const &str;

Hi All,
This is an existing paragraph formatting for bullet
pf=GetParaFormatSelection();
pf.dwMask = PFM_NUMBERING | PFM_STARTINDENT;
pf.wNumbering = PFN_BULLET;
pf.dxStartIndent = 300;
SetParaFormat(pf)
Like this I would like to create own paragraph formatting.For example"<>".
Thanks,

I have the handlers and message maps as below.
Whenever a child window is visible the following hanldler and its update function is not invoked.
When the Child window is closed they are invoked..
Can anyone explain this behaviour.
ON_COMMAND(ID_VIEW_DRAWTOOLBAR, OnDrawToolBar)
ON_UPDATE_COMMAND_UI(ID_VIEW_DRAWTOOLBAR, OnUpdateDrawToolBar)
void CMainFrame::OnDrawToolBar()
{
if (m_bUICtrlBar)
{
m_bUICtrlBar = false;
ShowControlBar(&m_UICtrlsBar, m_bUICtrlBar, false );
}
else
{
m_bUICtrlBar = true;
ShowControlBar(&m_UICtrlsBar, m_bUICtrlBar, false );
}
}
void CMainFrame::OnUpdateDrawToolBar(CCmdUI *pCmdUI)
{
if (m_UICtrlsBar.IsVisible())
m_bUICtrlBar = TRUE;
else
m_bUICtrlBar = FALSE;
if (m_bUICtrlBar)
{
pCmdUI->SetCheck(TRUE);
//AfxMessageBox("visible so check");
}
else
{
pCmdUI->SetCheck(FALSE);
//AfxMessageBox("Invisible so Uncheck");
}
}

hello!
i want to create check boxes on run time in the groupbox but i dont know how to do this plz tell me.and give detail procedure
|
|
|
|

Connect a variable to your groupbox: CButton m_Stat;
1-
CreateWindow("BUTTON","this is checkbox",WS_CHILD | WS_VISIBLE | BS_CHECKBOX | BS_AUTOCHECKBOX | WS_TABSTOP,20,10,200,20,m_Stat.m_hWnd,NULL,AfxGetApp()->m_hInstance,0);
-OR-
2-
You can also use CButton: Just make the CButton variable at class level.
static CButton b;
CRect rect;
rect.SetRect(20,20,200,40);
b.Create("Hello oo",WS_CHILD | WS_VISIBLE | BS_CHECKBOX | BS_AUTOCHECKBOX,rect,&m_Stat,20);
If you need to use plain win32, then it is a bit different.
this is this.

|
|
|

but this create only single checkbox and i want to display single check box on each click event.means i want to display 1 checkbox then on next click event another next to previous.
|
|
|
|
|
well you did not say so on your initial post ...
but I still don't understand what you want to do ?
you want to create a new checkbox control each time the user clicks somewhere ?

ya actually i want to open no of files at same time and each time when i click on open file on file menu a check box would be created on each open file action as i would open another file the next check box would be opened on group box next to previous one.
hope u'll understand now

Create a CPtrArray m_ptrArray; variable in your header.
Then when you want to create the checkbox,
CButton* pButton;
pButton = new CButton;
...
Create the button using the code in reply above.
...
Then add it to the array like this:
m_ptrArray.Add(pButton);
Now your checkbox is created and added to the array for later usage.
When you need to access it, use:
CButton* pButton;
pButton = (CButton*)m_ptrArray.GetAt(iLocation);
where iLocation is the index of the button starting with 0...to m_ptrArray.GetSize();
this is this.
