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 )"

regards

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 Wink | ;)

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)
{
}

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.

Can not copy from RichEdit control

White Owl14-Apr-06 11:49

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);

Windows 2003 server / remote desktop

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.

How to call a Visual C++, Dialog Based, member function

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.

EW_dude wrote:

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 />
// ...<br />
BOOL CProjectApp::InitInstance(void)<br />
{<br />
 // ...<br />
 CProjectDlg dlg;<br />
 g_pTheDlg = &dlg;<br />
 dlg.DoModal();<br />
 // ...<br />
}<br />

How to move a file based on its extension only?

Lynniz14-Apr-06 7:43

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!!!

1. find all files with that extension (FindFirstFile / FindNextFile)
2. move them one at a time (MoveFile)

I actually figured out an alternative way. I am using the Gdal Library with C++. Instead of declaring a name for the file at the beginning, I directed the file to the destination folder first and then named it. It might sound little confusing since I am not using straight C++.

I would still like to know if there is a way to move the file by extension only in C++.

Thank you,

Lynniz
