When you create an MFC project, you may choose between an SDI, MDI or Dialog-based. In Dialog-based, we can create buttons, lines, and other controls but in SDI, you have to insert a dialog to place your buttons, etc.
I would like to ask if it is possible to place these dialogs, edit boxes, static text, etc to the main window of the SDI or MDI? if yes, how, just a snippet will do? Thanx Smile | :)

Yes, when creating your project, on the last step of the creation wizzard, you can choose from which class view (CView, CScrollView, CFormView,...) your main view class will inherits of. Just choose CFormView and a form will already be ready for you. You just need to place the controls you want on it.

No code snippet necessary Wink | ;)

to create a control declare an object of that control class eg CEdit, CStatic etc in ur view class and then call Create function of these classes in OnCreate function of ur view class

Hi,

I m opening a file and trying to read a content of it..but in buffer it gives me nothing. Is it coz the pointer goes to end of the file??? whats thereason to not get data....here is code

DWORD buff;
TCHAR *szBuffer = NULL;

HANDLE hr = CreateFile(L"c:\\a.txt",FILE_READ_DATA,FILE_SHARE_READ,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);

ReadFile(hr,&szBuffer,10,&buff,NULL);

If you are opening Text File why Not go for CStdioFile and CFile class.. Thats work well with The Text or binay file!...

No

The reason is ReadFile doesnot allocate memory for szBuffer .
Use this code

DWORD buff; 
TCHAR szBuffer[SOME_SIZE] ;

HANDLE hr = CreateFile(L"c:\\a.txt",FILE_READ_DATA,FILE_SHARE_READ,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);

ReadFile(hr,szBuffer,SOME_SIZE,&buff,NULL);

Check the second and third parameters. They should be:

ReadFile(hr, szBuffer, sizeof(szBuffer), &buff, NULL);

Playing *.avi files[modified]

Hello guys,
I have a MFC dialog based application , where I want to play *.avi files.
Suppose I have a button "Load video" and after clicking it and choosing the specified *.avi file , I want to be able to play(pause,stop) the video in my dialog.

Any suggestions on how to do it?

PS. I had problems with CAnimateCtrl , When I tried to Open the file :

if(!m_animate.Open("c:\\file.avi"))
   MessageBox("Could not open video");

I got the latter MessageBox. Though file.avi existed on C: disk.

Just a check.
Does file runs in media player?
Do you have necessary rights on file?

But is not there another way to play *.avi files without using CAnimateCtrl

I do not have any experience with using ActiveX controls.
Could you give me little tips on how to do this, I am using Visual Studio.Net 2003.

Thanks in advance

in the dialog editor view, right click on the tool bar panel, choose add/remove items. on the next dialog, choose com components tab and tick windows media player in the list. click ok and then u can use it like any other control.

thanks for help , but on little thing more.
i have done everything but when I write m_player.openPlayer("c:\\file.avi"); New instance of MediaPlayer is opened and the file is played there.
But I need the video to be played inside my dialog so I thought this should do the job :
m_player.launchURL("c:\\file.avi");
But I get a error MessageBox with empty text Confused | :confused:

Do you have any idea what is wrong??

Yes, you need to use the setURL() method.

CAnimateCtrl::Open() simply sends a ACM_OPEN message to the control. Per MSDN, that message will fail if the .avi file contains any audio. Do you think this is the case?

Yes David now I took a better look in MSDN and found :
"Open does not support sound in an AVI clip; you can open only silent AVI clips"
And my video of course contains audio.
Then can you help me with opening and playing *.avi - s with audio?

Thanks in advance

I think you might have to consider using one of the ActiveX controls (e.g., Windows Media Player from wmp.dll, Microsoft Multimedia Control from mci32.ocx).
