Hi, I am trying to write a fullscreen game... and I have a question about the message loop
I am curently using the following form:
<br />
while(msg.message!=WM_QUIT)<br />
if(PeekMessage(&msg,0,0,0,PM_REMOVE)){<br />
TranslateMessage(&msg);<br />
DispatchMessage(&msg);<br />
}<br />
else Render();<br />
whitch ain't so bad for the momment, but in future it's gonna have multiplayer
and user input,and other stuff.I saw in Quake3's source the loop was way diffrent.
And now the question:
Can anyone(hwo had previously worked whit somethings like that ...hopefully)give me an ideea
about how the message loop should be like.

The Quake 3 source isn't that much different (and neither is most other PC games message loops):
WPARAM MainLoop()
{
MSG msg;
while (1)
{
if (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
{
if (msg.message == WM_QUIT)
break;
TranslateMessage(&msg);
DispatchMessage(&msg);
}
else
{
}
}
return msg.wParam;
}
It really isn't that much different than what you have.

Hi,
i have another stupid question 
In my MDI project i added a new MFC class of type Base-type CDialog.
Then i put some buttons on it and by a keystroke on a MDI Child Window
i execute this code :
if(nChar == 112) { // If F1 Key
CWnd *Con = GetFocus(); // the selected Control
WinTEdit Help(this);
if(!Help.Create(IDD_WINTEDIT,this))
int error = 1;
Help.ShowWindow(SW_SHOW);
}
Help.Create return always false
In my source code of the WinTEdit(CDialog) i doesn't change anything
It's certainly a little config that crashes the creation 
Thanks

I think WinTEdit is CDialog if you run this code what happens?
<br />
<br />
if(nChar == 112) {
CWnd *Con = GetFocus();
<br />
WinTEdit *Help;<br />
Help=new WinTEdit(this);<br />
Help.ShowWindow(SW_SHOW);<br />
}<br />
<br />
<br />
WinTEdit::WinTEdit(CWnd* pParent )<br />
: CDialog(WinTEdit::IDD, pParent)<br />
{<br />
Create(WinTEdit::IDD,pParent);<br />
}<br />
|
|
|
|
|
WinTEdit::WinTEdit(CWnd* pParent /*=NULL*/)
: CDialog(WinTEdit::IDD, pParent)
{
Create(WinTEdit::IDD,pParent);
}
causes the same problem 
It's seriously possible to open a CDialog in a MDI-Project, or not?
Or isn't it possible to open a CDialog with a "CFormView"-Parent?
So that only the mainform could open the CDialog...
Thanks

After call to thread function and then we process some job in main program.
How to check from main program, the thread function is working or not.
|
|
|
|
|
If you still have a handle to the thread, you can call GetExitCodeThread to see if it's still running. If you want to wait for it to finish running, pass the handle to one of the wait functions (e.g. WaitForSingleObject).

I use this function..
AfxBeginThread(Thread,this);
for start thread.
Please advise me how to get handle to the thread.
|
|
|
|
|
Something like
CWinThread* pThread = AfxBeginThread(...);
HANDLE hHandle = (HANDLE)pThread;

Hi,
I am trying to convert wide character string to ASCII string. I get WideCharToMultiByte() API function to do this task. Now when I am using this function it gives me “ERROR_INVALID_PARAMETER” error. Can I know where I am going wrong?
wchar_t* wStr = L"test string";<br />
int wLen = ::wcslen(wStr);<br />
char* aStr = NULL;<br />
int aLen = ::WideCharToMultiByte(CP_ACP,0,wStr,wLen,NULL,0,NULL,NULL);<br />
int eCode = ::WideCharToMultiByte(CP_ACP,0,wStr,wLen,aStr,aLen,NULL,NULL);

From the top of my head:

aStr must point to a valid buffer to recieve the converted multibyte string.

If I want to use DirectX for writing commercial apps, do I have to pay Microsoft for that. Will it be OK if I buy only Visual Studio 6.

Using DirectX for a commercial application does not require paying a license.

No. Last time I checked, you have to pay ME to do that

Hi all,
I've a button to move to the next point in a plot
when the button is pushed.
The matter is that i must click on the button many times
if i wanna continue to pass to the next point in the plot,
while i would like to obtain this keeping clicked the button.
How can i do that ?
Thanx in advance,
Desmo16.

OnButtonDown:
start a timer
OnTimer:
move the selection to the next point
OnButtonUp:
stop the timer
|

I suggest you override CButton and create a button class that repeats the BN_CLICKED event.
Have a look at Joe Newcomer's article here[^] for tips on how to accomplish this behaviour.
You could even have more than one timer event to make the BN_CLICKED events generated with higher frequency if the button is kept down for a longer time.

Set timer and send BN_CLICKED message from it!

Hello!
HWND hWnd = FindWindow("Shell_TrayWnd","");
if(hWnd != NULL)
{
RECT rect;
GetWindowRect(hWnd, &rect);
int height = rect.right - rect.left;
int width = rect.bottom - rect.top;
}

I suppose you could subtract the height of the desktop's client area (i.e., SystemParametersInfo(SPI_GETWORKAREA, ...)) from the height of the screen (i.e., GetSystemMetrics(SM_CYSCREEN)). The difference would be the height of the taskbar. For an MFC solution, something like:
CWnd *pTaskbar = CWnd::FindWindow("Shell_TrayWnd", NULL);
CRect rc;
pTaskbar->GetWindowRect(rc);
int nWidth = rc.Width();
int nHeight = rc.Height();

Call SHAppBarMessage(ABM_GETTASKBARPOS). No sense searching through windows when there's an API that does exactly what you want.
