Hi everyone,
I had build a graph with the following,
IGraphBuilder *pGraph ;
IMediaControl *pMediaControl ;
IVideoWindow *pVidWin ;
IMediaEventEx *pEvent;
I tried to play many files continuously so i created a list ctrl , its playing fine, BUT the problem i was facing is when one file is played and going to next file i release the above variables, so i am getting a blank screen like a flash.... i dont want that blank screen on the playing screen ... can anyone help me with this ... the movement from one file to other should be without the blank screen
Thanks in advance
With Regards

do a google search for GMFBridge written by Geraint Davies. His ClipPlayer example sounds like what you are looking for.

Try a separate thread dedicated to JUST socket I/O.
Use WSAEventSelect() to have an event object signaled on FD_READ (and maybe FD_CLOSE).
Use this event to wake your I/O thread and recv ALL received bytes (call recv until you get
WSAEWOULDBLOCK error), adding the received bytes to a buffer each call. Loop and wait again on the
event. Let another thread process the received data.
This works very fast even on TCP/IP because you are keeping the receive buffer flushed.
Much better than doing it on the UI thread through Windows messages like you are now.

Hi,
The values you supplied must be formatted with valid qualifiers that matches the DATA TYPE of the column where you want to insert it to.
Example if Column-name1 is a date then value1 should be like #value1#
if it is a string value1 should be 'value1'
Hope this help.

use win32's createProcess(....) function... call this function in the MFC's button click handler function.. it will run new exe as a seperate process... refer MSDN for detailed documentation.

I met a strange problem.
This is my code
#include "stdafx.h"
#include <iostream>
#include <windows.h>
#include <mmsystem.h>
#pragma comment(lib, "winmm.lib")
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
DWORD datasize = 48000;
HWAVEIN mh;
WAVEFORMATEX wf;
wf.wFormatTag=WAVE_FORMAT_PCM;
wf.nChannels=1;
wf.nSamplesPerSec=8000;
wf.nAvgBytesPerSec=8000;
wf.nBlockAlign=1;
wf.wBitsPerSample=8;
wf.cbSize=0;
int r;// = ;
cout << "poo1";
int k = waveInOpen(&mh,WAVE_MAPPER,&wf,NULL,0L,CALLBACK_WINDOW);
cout << k;
cout << "poo2";
if (k == MMSYSERR_NOERROR)
cout << "success";
else
cout << "fail";
cout << "poo7";
//WAVEHDR mp;
//mp.dwFlags=0;
//mp.dwUser=0;
//mp.dwLoops=0;
//mp.dwBytesRecorded=0;
//mp.lpData = (char *)GlobalLock( GlobalAlloc(GMEM_MOVEABLE|GMEM_SHARE, datasize) );
//memset(mp.lpData, 0, datasize );
//mp.dwBufferLength = datasize;
//int p = waveInPrepareHeader( mh, &mp, sizeof(WAVEHDR) );
//cout << p;
cout << "poo4";
//waveInAddBuffer
int i ;
r= waveInGetNumDev();
cout << "poo5";
cout << r ;
cin >> i ;
//cout << " " << endl;
return 0;
}
and It runs the result following
poo0poosuccesspoo3
It's strange.
I change the code, but the program dont know.
Can somebody help me?

It's called caching. You need to end each of the cout statements with endl.

Handle the WM_MOUSEMOVE message. Each time your handler function gets called, you'll need to determine if you are moving left or right (based on the previous values). Move the slider control accordingly.

hi,
I want to write my program settings into a configuration file, but I have CString object and CArray data structures, so what is the best way to do this?
My structures look like:

{<br />
struct FavoriteElement<br />
{<br />
CString strName;<br />
CString strPath;<br />
};<br />
CArray<struct FavoriteElement,struct FavoriteElement> Elements;<br />
tagFavoriteSettings(){}<br />
}FavoriteSettings;
Thanks alot
