so confused! - C / C++ / MFC Discussion Boards

Yeah,
if you don't mind i have a suggestion use Waitforsingleobject api inside the thread for wait for event which would set it self every time timer message arrived for example-->

your thread ->
void thread(lpvoid p)
{
while(1)
{
WaitForSingleObject(event);
----
your functioning
-------
-
--
}
}

and
OnTimer(UINT nIdEvent)//timer function
{
SetEvent(event);
}

simple and consise way for creating service

I want to know:
There is any free compiler under windows for c++?
And, there is any free graphical develop under windows too?

Elfo,thanks

GCC+Eclipse?
I have not used either, but have heard it is not bad, and can work together.

Hi,

The Microsoft Visual C++ compiler is available for free and can be downloaded at:

http://msdn.microsoft.com/visualc/vctoolkit2003/

A preview of the upcoming Visual C++ 2005, coming with a complete graphical IDE can be gotten at:

http://lab.msdn.microsoft.com/express/visualc/default.aspx

Cheers.

You can download the MS Visual C++ 2003 toolkit from microsoft here[^]. It's free, and includes the same C++ compiler distributed with Visual Studio 2003.

GCC comes in two versions for windows, cygwin, and mingw.
http://www.cygwin.com/
http://www.mingw.org/

I've used the latter, though not much. Either will work, check them both out as there are differences that might matter to you.

By "free graphical develop" what do you mean?

Hey guys...How would I go about writing this in the .cpp file?

MOSTLY THE BOOL METHODS I AM HAVING TROUBLE WITH

This is what I have for the Menu.h file

#ifndef CONNECTFOUR_H
#define CONNECTFOUR_H
#include "Menu.h"//includes Menu header file

using namespace std;

class ConnectFour
{
private:
//date members
int board[12][13];
int numChips[7];

public:
ConnectFour();
//default constructor
bool playTurn();
/*gives a player the opportunity to place a chip into the board. This should be a Boolean function to return true if this turn produces a winner (otherwise false should be the return value).*/

void displayBoard();
/*places 2 different kinds of markers on the board (one for each player) and displays some kind of marker for empty slots. Be sure your choices are easy to see.
*/
void dropChip();
//places a chip into the board and looks for a winner

void checkWinner();
//should call 4 helper functions (you choose the names) to check the 4 possible winning moves – 4 in a row vertically, horizontally, or diagonally. These helper functions should look only at possible wins produced by this last move – they should not check the entire board!

void verticalwin();
//this method checks to see if 4 colors match to win the game vertically

void horizontalwin();
//this method checks to see if 4 colors match to win the game horizonatally

void diagonalwin1();
//this method checks to see if 4 colors match to win the game diagonally one way

void diagonalwin2();
//this method checks to see if 4 colors match to win the game diagonally the second way

bool determineDraw();
//method determines if the game is a draw (full board with no winner). This method returns true if the game is a draw and false if not.

};
#endif //ends ConnectFour.h

All I have left for my ConnectFour.cpp is ...

#include <iostream>
#include <string>
#include "ConnectFour.h"//includes ConnectFour header file

//default constructor will initialize zero to the data private members (variables)

ConnectFour::ConnectFour()
{
board[12][13] = 0;
numChips[7] = 0;

for(int i=0; i < 12; i++)
{
for(int j=0; j<13; j++)
{
board[i][j] = 0;
}
}

for(int i=0; i<7; i++)
{
numChips[i]= 0;
}
}

bool ConnectFour::playTurn()
{

}

You have to return a value in the bool-Method.

return true;

Hello,

void verticalwin();
void horizontalwin();
void diagonalwin1();
void diagonalwin2();

I think these functions should also return boolean datatypes, like determineDraw function.

If you will do this, you can just check if any of these functions returned a true value. And hence, determine if there has been a winner.

maybe like this:

bool ConnectFour::playTurn()
{
// TODO:
// Get the column input here

return (verticalwin() || horizontalwin() || diagonalwin1() || diagonalwin2());

}

So, what exactly is the problem? Does code compiles? or what? Confused | :confused:

Here's a bit of code that automates the VC6 debugger, what's the VC7 version look like ?

void Debug()
{
HRESULT hResult;
DSSharedObjects::IApplicationPtr pIDevStudioApp;

DSSharedObjects::IDocumentsPtr pIDocuments;
DSDebugger::IBreakpointsPtr pIBreakpoints;
_bstr_t bstrTemp;
if(SUCCEEDED(hResult = pIDevStudioApp.CreateInstance(__uuidof(
DSSharedObjects::Application))))
{
pIDevStudioApp->PutVisible(VARIANT_TRUE);
if(((pIDocuments = pIDevStudioApp->GetDocuments()) != NULL) &&
((pIDebugger = pIDevStudioApp->GetDebugger()) != NULL) &&
((pIBreakpoints = pIDebugger->GetBreakpoints()) != NULL))
{
bstrTemp = _T("Program.exe");
pIDocuments->Open(bstrTemp);
pIDebugger->Go();
...
}
}
}

void Debug()
{
HRESULT hResult;
CComPtr<envdte::_dte> spIDevStudioApp;
CComPtr<envdte::window> spMainWindow;

CLSCTX_LOCAL_SERVER)))
{

I want to know which method can be applied to communicate between two computers belong to the different domain besides SOCKET

What's wrong with sockets?

I want to if two computers belong to different domains and A has authority of administrator of B,whether A can write data in the shared writable directory of B

If A has administrator authority of B, then A can write to a shared writable directory on B.

i have a uni assignment that requires multi-threading. I want to call a function to begin the thread that takes several parameters. I have found examples on how to pass single parameters and tried to pass several param's in the same manner.

I am using _beginthread(functionName, 0, parameters);
Does anyone know of a way that i may be able to pass several parameters to this thread??

Thanks

Steve

err... make a struct that holds them and past that? Thats what I do.

ok thanks for that

Steve

HHOOK hKeyHook;

__declspec(dllexport)
LRESULT CALLBACK KeyEvent (int nCode,WPARAM wParam, LPARAM lParam)

{
if( (nCode= HC_ACTION) && ( (wParam = WM_SYSKEYDOWN) || (wParam = WM_KEYDOWN) ) )
{

KBDLLHOOKSTRUCT hooked *= *((KBDLLHOOKSTRUCT*)lParam);
DWORD dwMsg;

dwMsg += hooked.scanCode <<16;
dwMsg += hooked.flags << 24;

char lpszName[0x100] = {0};

lpszName[0] = '[';

int i= GetKeyNameText(dwMsg,(lpszName+1),0xff) +1;
lpszName[i] = ']';
printf(lpszName);
}

I want to hook the keyboard but the KBDLLHOOKSTRUCT struct keeps giving error even with the intelisense showing the members of the struct.
I dont really get it

Here are the errors

error C2065: 'KBDLLHOOKSTRUCT' : undeclared identifier
error C2059: syntax error : ')'

among other stupid errors.
Can anyone help me?
Tks in advance

This line is incorrect:

<br />
KBDLLHOOKSTRUCT hooked *= *((KBDLLHOOKSTRUCT*)lParam);<br />

Change it to:

<br />
KBDLLHOOKSTRUCT* hooked = (KBDLLHOOKSTRUCT*)lParam;<br />

This should clear up the errors.

Also, your IF statements are goofed up...
Which immediately lets me know you did not turn your warning level to 4 or you are ignoring WARNINGS during your mopile, because the compiler would otherwise warn you about "Assignment within conditional expression".

Try changing this:

if( (nCode= HC_ACTION) && ( (wParam = WM_SYSKEYDOWN) || (wParam = WM_KEYDOWN) ) )

to this:

if( (nCode == HC_ACTION) && ( (wParam == WM_SYSKEYDOWN) || (wParam == WM_KEYDOWN) ) )

I usually try to place the contant on the left hand side, because such code will NOT compile if you made such a similar error:

if( (HC_ACTION == nCode) && ( (WM_SYSKEYDOWN == wParam) || (WM_KEYDOWN == wParam) ) )

Since your IF is wacked, you are probably processing messages you should not be, at times.

I have figured out how to spy on an apps menu for remote control, but cannot determine how to do the same for the apps context menus.

How do you determine the commands sent from a context menu?
