Guys,
I have a question concerning blitting to a DirectDraw7 surface using Blt. My objective here is to take the source surface, lets call it XYSurface, and blit it back onto itself, simply rotating it during the blit. Can I do something like this?
<br />
LPDIRECTDRAWSURFACE7 pXYSurface;<br />
RECT rc;<br />
GetClintRect(hDlg, &rc);<br />
<br />
hRet = pXYSurface->Blt(&rc,pXYSurface,&rc,DDBLT_ROTATIONANGLE,&ddbltfx);<br />
<br />
if(hRet != DD_OK)<br />
{<br />
HandleDDErrors(hRet, errorMessage);<br />
MessageBox(NULL,errorMessage,"Error",MB_OK);<br />
return -1;<br />
} <br />
When I do this, hRet is DDERR_SURFACEBUSY. Which reveals that "Access to the surface is refused because the surface is locked by another thread." Is this because I am trying to Blit back on to the source?
Thanks,
Joe

Hello Friengs,
Yes yes I know there is a function called GetCurrentProcessID(),which returns the process ID of current Process.
But the problem is I am creating to many processes(like notepad ) and i want to know currently on which process the user is working.I tried the above function but it gives me different process Id.Now i dont know what to do.

AfxBeginThread return the CWinThread object pointer.
And that class contains the member CWinThread::m_nThreadID.
It helps?

It's a member of the PROCESS_INFORMATION struct that you passed in a call to CreateProcess()

Hello
I am trying to use Directshow 9.0 for making an audio player. I use VC++/VS6.0.
I have written a sample grabber filter because I want to do some processing with the audio samples before they are played.
The sample grabber always picks a buffer of a fixed size but I want that size to be configurable. I did some search for the solution and found out that we need to override teh DecideBufferSize method for the output pin. I did that but my DecideBufferSize code is never called. Am not sure where I went wrong.
Can anyone plz guide me how this can be handled.
This is the flow-
I input come from a wav file so I take the output pin from that source. For this output pin I have overridden the DecideBufferSize funtion.
Then this goes to teh input pin of the sample grabber and in the sample grabber callback I do the audio processing.
The output pin of the sample grabber is rendered.
Any help(suggestions or sample code) would be appreciated.
Thanks

Hello,
I use the following funktion to write log info into a write protected CEdit window for debuging purposes:
void CMyprogDlg::log(LPCTSTR lpszText)
{
long iBegin, iEnd;
CString time;
CString msg;
time = m_CTime_time.Format("%d.%m %H:%M:%S");
msg.Format("[%s] %s", time, lpszText);
iBegin = m_CEdit_log.LineIndex(-1);
iEnd = iBegin + m_CEdit_log.LineLength(iBegin);
m_CEdit_log.SetSel(iBegin, iEnd);
m_CEdit_log.ReplaceSel(msg);
}
for example :
log("blablabla\r\n");
It works well and i'm using it in alot of programs instead of stdout.
The problems is that when i'm trying to put a lot text lines in the window, after a few hundred lines, the function doesn't work as supposed anymore. Instead of creating new lines, the new text replaces the last line.
I'll be very greatfull for any help!
Best Regards,
im79

Edit controls do have an upper limit (64KB comes to kind). Try this instead.

You can use RichEdit control to over come this drawback of CEdit control.

Is it possible to disable a network connection and if so how?

Hmm but I need it in a program not a script.

The WMI classes can be used in code, script, or otherwise.

In Debug mode it's plotting graph but in release mode does not,
wt might be the reason??
Thanks..

Do you check that the variables that are being used by you are being initialized properly. A variable may have a different value in the release and in the debug build, causing the differing behavior. And if you go back and see where the value of that variable is set, you will most probably find out that it isn't: You simply forgot to initialize that variable. The reason why the debug build seemed to work is that the debug version of the runtime library initializes dynamic memory and stack variables to known values (in order to track down memory allocation and overwrite errors), while the release version of the runtime library doesn't.
This could very well be just one of the many possible reasons....
Somethings seem HARD to do, until we know how to do them.

Hi everybody,
in which way is it possible to send messages to a process on another computer
over network and internet?
Is it possible to get the STD_OUTPUT_HANDLE of these process on another maschine? I don't think so
I think the easiest way to send the output from a console-application over network is to send each
caracter or caracter-array and the opposide maschine works like a Client and displays those caracters on the screen, or?
Big thanks for suggestions

In most cases, all of them[^].

You can make the dialog resizable and with scrollbars (it's a dialog style), but then you have also to handle scrolling by repositioning the controls according to the thumbs positions.
Anyway, if you have large "dialogs" you've probably created a wrong metaphor in the user interface.
Good dialogs shouldn't be wider than about 600 x 400 (otherwise they must be prepared to handle scrolling and zooming).
So consider the idea to break your dialog in multiple "pages" using tabbed dialog pages.
It will probably end in a better usability than a scrollable dialog.
