yyin = fopen( yytext, "r" );
yy_switch_to_buffer(
yy_create_buffer( yyin, YY_BUF_SIZE ) );
these can only associate the input buffer with a file. However, creating new file is prohibited under my envirment.
Are there any good ways to solve this problem?
Best Regards,

For That you have make changes System Menu
here are some codes
#1 Get system Menu
ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);
ASSERT(IDM_ABOUTBOX < 0xF000);
CMenu* pSysMenu = GetSystemMenu(FALSE);
if (pSysMenu != NULL)
{
CString strAboutMenu;
strAboutMenu.LoadString("about box");
if (!strAboutMenu.IsEmpty())
{
pSysMenu->AppendMenu(MF_SEPARATOR);
pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
}
}
for handling Menu Message you have to overide
WM_SYSCOMAND message. i.e. this way
void CSockDlg::OnSysCommand(UINT nID, LPARAM lParam)
{
if ((nID & 0xFFF0) == IDM_ABOUTBOX)
{
CAboutDlg dlgAbout;
dlgAbout.DoModal();
}
else
{
CDialog::OnSysCommand(nID, lParam);
}
}
this code is wizard generated but help very much

Thank you for your such quickly reply.
Yes, I use the nID to get the message. I set one breakpoint at the first of the function OnSysCommand(..) and could get the mouse left click when minisize the main window, but if i use the right click, nothing happen, i got none message and my breakpoint even can not be called!
it seems no message pass in when i use the right mouse click?!
Thanks again for your help!

I have a program that all driverd from CDialog, and all have a member function - CString GetFuncName(),and use it like following
void ShowFunctionName(int functionid,CObject* functionobj)
{
CString msg;
switch(functionid)
{
case 1:
msg.Format("Function is %s",((CFunction1*)functionibj)->GetFuncName());
break;
case 2:
msg.Format("Function is %s",((CFunction2*)functionibj)->GetFuncName());
break;
......
}
MessageBox(msg);
}
I want to simplify code as following
void ShowFunctionName(int functionid,CObject* functionobj)
{
CString msg;
msg.Format("Function is %s",((CDialogEx*)functionibj)->GetFuncName());
MessageBox(msg);
}
So I create CDialogEx as following
class CDialogEx : public CDialog
{
public:
CDialogEx(){CDialog::CDialog();};
~CDialogEx(){CDialog::~CDialog();};
CDialogEx(LPCTSTR lpszTemplateName, CWnd* pParentWnd = NULL){CDialog::CDialog(lpszTemplateName,pParentWnd);};
CDialogEx(UINT nIDTemplate, CWnd* pParentWnd = NULL)
{
CDialog::CDialog(nIDTemplate, pParentWnd);
};
public:
virtual CString GetFuncNameg() {CString rtn; return rtn;};
};
and all the functions CFunction1~CFunctionn all chage inherit from CDialog to CDialogEx,And Change the constructor ( :CDialog( .. to CDialogEx(...)
CFunction1::CFunction(CWnd* pParent /*=NULL*/)
: CDialogEx(CFunction::IDD, pParent)
But when the progame run at
CFunction1 dlg;
dlg.DoMoal();
It Will cause the "Debug Assertion Error" and terminate program
Can anybody give me a sample source like abuout "How to create and use an Extened Dialog Class?"
or hint me where has the sample.
My tool is Visull C++ 6.0

Hi
I am working in vc++. I have to write a keyboard hook program. I have to trap all the pressed keyboard keys. For ex: if Key ’a’ and Key ‘b’ are pressed simultaneously, then my program should get a message that Key ‘a’ and Key ‘b’ are both pressed. I should be able to capture all pressed and released key events simultaneously at once. Can anyone please give me some inputs for me to proceed ahead?
Thanks

Hey Madhavi,
I had a similar requirement recently. I did this:
1. Wrote a hook to listen to the keyboard only
2. When I got 'a' or 'A', checked the Key State of 'B' by calling GetKeyState('b') and GetKeyState('B').
3. If either of the KeyState functions returns a value with a hi-order bit of 1, you have your event....
If this does not work well , an alternative would be to listen for 'a', and when you get it, store the time, using GetTickCount. In the next keyboard event you get, check if it is a 'b', and if the time gap between the last stored time and the current time is less than , say, 100ms, then .. run the rest of your code.

Hi all,have you guys ever used the class CDirectSS defined in Xvoice.dll?
please tell me the way to change the speaker 's gender and make it speak slowly?Thanks you a lot!
Merry Christmas!!!

hi tiem, i found a vb6 project that uses the xvoice.dll. you may be able to use it. based on my project there is a property .CountEngines that lists the number of voices, in my case 8. so i used a list box to select each voice like this in vb6: spkSpeak.CountEngines =
val(ListBox.Text). I could not make the .gender property work, but using this approach I have 5 female voices and 3 male voices. very truly yours, joe / orange / virginia / usa / joeinorange2@aol.com

Hi,
I am new to .NET.
I have a managed .NET DLL that I need to use with some of my visual C++ code. (I have both Visual C++ 6.0 and Visual Studio .Net).
My understanding is that all the information (.lib .h) is contained within this .Net DLL and that it is all I need.
How do I incorporate this into my c++ app or solution, reference the calls and link successfully?
First, Can I do this and second, how do I go about doing it?
Thanks for you help

Hello,
I have a project that crashes at run-time due to an Access Violation. The violation occurs in a section that looks something like this:
double var;
for (iter = ptrA->getPtrB()->getCList().begin();
iter != ptrA->getPtrB()->getCList().end();
iter++)
{
var = iter->getVar();
}
A, B, and C are classes that have been defined elsewhere.
iter is an iterator of type std::list<c>.
ptrA is a pointer to an object of type A.
ptrB is a pointer to an object of type B.
getCList is a method in the B class that returns a list of C objects.
I have changed the names of the variables for simplicity.
When I debug at run time it brings me to the line starting with "for".
I cannot figure out where the problem is. My only hunch is that it might have something to do with the fact that the list that getCList() returns is actually NOT a list of C objects. Rather, it is a list of "D" objects where D is a class derived from C. Is that a problem? Does anyone else have anything else to suggest checking in the class definitions or anywhere else? I'd be happy to post more code if anyone thinks that would help...
Thank you!

I can't figure it out because your codes are too complicated!
I suggest you modify it like this:
somelist listsome& = ptrA->getPtrB()->getCList();
for (iter = listsome.begin();
iter != listsome.end();
iter++)
{
var = iter->getVar();
}
Because the first ptrA->getPtrB()->getCList() may be not as the same as your second ptrA->getPtrB()->getCList().

Hi Jordan,
I assume that getCList is defined like so:
list<obj> getCList()
Instead of getCList returning a list, I suggest it returns a reference to the list. Meaning, your function will change to this:
list<obj>& getCList() // just a small ampersand added...
I'm sure if you make this change in the function declaration, the rest of your code will work just fine.

Hello,
Thank you both for your replies. It seems like you were both suggesting different flavors of the same idea. I tried both implementations and in both cases I still had a runtime error of "Access Violation". In this case, however, the debugger brought me to a spot in the file XTREE (which I assume is part of the STL?) instead of to the line in my code. Do you have any other suggestions?
Also, I'm still wondering if the iterator is having a problem with the list I am retrieving being a dervied class rather than the class the iterator was created with.
Thanks,
-Jordan

I 2 global variables:
bool PrintBoard[5][5];
bool MemoryBoard[5][5];
Then I have a function:
void DoMove(int x,int y)
{
x--;
y--;
PrintBoard[x][y] = !PrintBoard[x][y];
if (y > 0) {
PrintBoard[x][y - 1] = !PrintBoard[x][y - 1];
}
if (y < 4) {
PrintBoard[x][y + 1] = !PrintBoard[x][y + 1];
}
if (x > 0) {
PrintBoard[x - 1][y] = !PrintBoard[x - 1][y];
}
if (x < 4) {
PrintBoard[x + 1][y] = !PrintBoard[x + 1][y];
}
return;
}
As you can see, the DoMove function only changes PrintBoard.
I would like it to be able to change either variable with out much more code (I don't see the point of re-using code here).
I was thinking I could do something like adding another argument to the function that I could pass the global to it, but I couldn't figure out how.
Any Ideas? Thanks

void DoMove(bool Array[][5], int x, int y)
{
x--;
y--;
Array[x][y] = !Array[x][y];
...
}
...
DoMove(PrintBoard, 2, 3);
DoMove(MemoryBoard, 3, 4);

I have an MFC app that ASSERTS in CWnd::WalkPretranslateTree with a message being sent to main window after my main window is destroyed as I exit the application. The ASSERT is becuase the HWND being checked is no longer a valid window. It is a fairly large application that compiles and executes without problem on my old WinXP Home (SP1) machine with MSVC6 - but does this ASSERT in my new WinXP Pro (SP2) machine - no change in code.
The offending message is in the range of message numbers for Registered Window message. It is not one that is registered by my program.
How can I track what this message is and what program sent this? Is there a way to list all Registerd messages? Is there a way to set SPY+ or some such program to watch for this message?
I would appreciate any help.

Hello friends
I would like to capture datalink frames passing through my network card using sockets. I have found the following code snippet in a Network Programming book
sd = socket ( AF_INET, SOCK_PACKET, htons(ETH_P_ALL);
to capture all the datalink frames, i.e., frames with source and destination MAC address .(UNIX environment)
Is there an equivalent in Windows ?

There are four guys trying to get home at night and in order to do so, they MUST cross a bridge. It's very dark and there is only one torch available. The bridge can ONLY support "TWO" person at a time. Now, a bomb has been set on the bridge which will explode in 18 mins. Due to the fact that each person's travelling speeds are different, therefore some will obviously take longer to cross than others.
The time that each person takes are as followed:
A = 1 min
B = 2 min
C = 5 min
D = 10 min
Torch = 1 Qty
Here's how it works: If D & A goes first, it'll require 10 mins for them to cross the bridge together. By the time A gets back with the torch to B&C...11 mins will be passed already.
The total time required is : 17 mins
the solution to it is:
A and B first - 2 minutes (max 2 )
A runs back with torch = 3 minutes
C and D Next = 13 minutes ( max 10 )
B comes back with the torch = 15 minutes ( max 5 )
A and B again = 17 minutes
Can anyone tell me the code to this problem in turbo c or vc urgent please please. many many thanks in advance.
