if i declare variable in the header
float front[4][3];
can i still initialize it with {} in the constructor?
front = {{1.0f, 1.0f, 1.0f},{-1.0f, 1.0f, 1.0f},{-1.0f,-1.0f, 1.0f},{1.0f,-1.0f, 1.0f}};

Static member arrays (whether const or not) can be initialized in their definitions (outside the class declaration). For example:
class WindowColors
{
public:
static const char *rgszWindowPartList[7];
...
};
const char *WindowColors::rgszWindowPartList[7] = {
"Active Title Bar", "Inactive Title Bar", "Title Bar Text",
"Menu Bar", "Menu Bar Text", "Window Background", "Frame" };

in case you dont want to make variable static you can do following in the constructor.
float _front[4][3] = {{1.0f, 1.0f, 1.0f},{-1.0f, 1.0f, 1.0f},{-1.0f,-1.0f, 1.0f},{1.0f,-1.0f, 1.0f}};
memcpy(front, _front, sizeof(float)*12);

How do I implement this?
tCircle::tCircle( double fNewX, double fNewY, double fNewRadix )
: cCenter.fX( fNewX ),
cCenter.fY( fNewY ),
nRadix ( fNewRadix )
{
}
I get the error "error C2059: syntax error : '.'" at "cCenter.fX( fNewX )"

If your class looks like this:
class tCircle
{
double fX;
double fY;
double fRadix
public:
tCircle( double fNewX, double fNewY, double fNewRadix );
};
Constructor implementaiton could be:
tCircle::tCircle( double fNewX, double fNewY, double fNewRadix )
: fX( fNewX ),
fY( fNewY ),
nRadix ( fNewRadix )
{}

No. I have
class tDot {
public:
float fX, fY;
};
class tCircle {
public:
tCircle( void );
tCircle( float, float, float );
tCircle( tDot, float );
public:
float fRadix;
tDot cCenter;
};
I'm having trouble with the 2nd constructor.
Thx

I would add a constructor to tDot.
class tDot
{
public:
float fX, fY;
tDot(float newfX, float newfY){ fX=newfX; fY=newFY; };
};
class tCircle {
public:
tCircle( void );
tCircle( float, float, float );
tCircle( tDot, float );
public:
float fRadix;
tDot cCenter;
};
tCircle::tCircle(double newX, double newY)
: cCenter( newX, newY)
{
}

That's it! thx

You should either use cCenter(fNewX, fNewY), assuming tDot have a constructor accepting two arguments or move cCenter.fX and cCenter.fY within the function body.

I am working win WinAPI (not MFC!). Created RichEdit control and it works fine except one small problem. If user select some text in RichEdit control and hit Ctrl+C - nothing goes to clipboard.
Here is creation code:
if (SearchPath(NULL, "RICHED32.DLL", NULL, sizeof(sBuf), sBuf, &s)>0) {<br />
hRE_Lib = LoadLibrary("RICHED32");<br />
} else if(SearchPath(NULL, "RICHED21.DLL", NULL, sizeof(sBuf), sBuf, &s)>0) {<br />
hRE_Lib = LoadLibrary("RICHED21");<br />
} else {<br />
hRE_Lib = NULL;<br />
}<br />
if (hRE_Lib == NULL) {<br />
MessageBox(NULL, "Can not find RichEdit library!", "Error!",<br />
MB_ICONEXCLAMATION | MB_OK);<br />
return 0;<br />
}<br />
<br />
hRichEdit = CreateWindowEx(<br />
WS_EX_CLIENTEDGE,<br />
"RICHEDIT", "",<br />
WS_CHILD | WS_VISIBLE | WS_HSCROLL | WS_VSCROLL |<br />
ES_LEFT | ES_MULTILINE | ES_AUTOVSCROLL | ES_AUTOHSCROLL | ES_WANTRETURN | ES_READONLY,<br />
1,1,50,100,<br />
hwnd, NULL,<br />
(HINSTANCE) GetWindowLong(hwnd, GWL_HINSTANCE),<br />
NULL);<br />
<br />
if(hRichEdit == NULL) {<br />
MessageBox(NULL, "Rich Edit Creation Failed!", "Error!",<br />
MB_ICONEXCLAMATION | MB_OK);<br />
return 0;<br />
}<br />
SendMessage(hRichEdit, WM_SETFONT, (WPARAM)hFont, (LPARAM)TRUE);<br />
Right now, I am thinking about using
SendMessage(hRichEdit, EM_SETEVENTMASK, (WPARAM)NULL, (LPARAM)ENM_KEYEVENTS);
with some code in WndProc which would wait for Ctrl+C and send selected text from RichEdit to clipboard. But may be problem can be fixed more easy?
BTW Ctrl+A already works in my RichEdit control, so I do not understand why Ctrl+C do not work by default. There is only simple text. I am adding it by command SendMessage(hRichEdit, EM_REPLACESEL, (WPARAM)FALSE, (LPARAM)TextBuffer);

Hi,
Can anyone tell me if it is possible to check if a program is running remotely ( using remote desktop ) or locally.
Is there any win32 API calls to detect this?
regards,
Easen.

Sure. Once you have access to the other machine's desktop, simply open Task Manager.

Can a program detect this automatically?
I ve written a program to be used only locally. I want to detect if someone try to start it using remote desktop. If this is the case, the program must show an error message and close it self.
I know that there are ways to do it using the Windows 2003 access settings. But I need the program to detect it automatically.

I do not currently know of a way for a program to detect if it is running locally or from within Remote Desktop.

When Visual Studio creates a Dialog Based C++ program it creates projectDlg.cpp and projectDlg.h.
How can a global function call a member function of the projectDlg class?
The glogal function is defined in projectDlp.cpp.
Thanks,
Kevin

get an instance of that object type, or make the member function static.

I tried the static approach. static void disp();
But to get the global function to compile I had to type
projectDlg::disp(); Got it to compile.
But now disp() doesn't see any of the variables of the class. I get "illegal reference to non-static member" when I try to set a variable.
Any ideas?

Of course. This is how static member functions work.

Because they are not static. Read up on what static means in a class.

give your global function a pointer to the dialog. the very simplest way to do this is to just create a global variable to hold that pointer, then have your dialog set it (maybe in the dialog's constructor - and be sure to set that pointer to NULL when the dialog goes away)
then you can do:
CMyDialog *g_pDialog = NULL;
void MyGlobalFuncion
{
if (g_pDialog)
g_pDialog->memberFunction();
}

No matter what types of project (dialog based, Doc/View ...) you are working or what types of tools (VC++, C++ Builder, ...) you are using, you are using the C++ Language. Everything just follows the rule of the C++ Language.
So you may just search for where the auto variable of type class CProjectDlg is. And then you know what to do.
For example:
void g_MyGlobalFunction(CProjectDlg* p) { }<br />
CProjectDlg* g_pTheDlg = NULL;<br />
BOOL CProjectApp::InitInstance(void)<br />
{<br />
CProjectDlg dlg;<br />
g_pTheDlg = &dlg;<br />
dlg.DoModal();<br />
}<br />

Is there a way to move a file to a different folder based on its file extension only? I want to move by the file's extension is because the program I wrote in C++ will create a file with the current date and time as its filename. I was wondering if any C++ functions would do that or any other alternatives.
Thanks in advance!!!
