YOu can attach yto a process using VC - if you're using v6.0 then select Build|Start Debug|Attach to Process and check the Show System Proceses button to see your service... then once attached, you can break and set breakpoints, etc.

You might want to make sure your service is set to interact with the desktop, it makes things go a bit easier while debugging with the Visual Studio debugger.

Are FSCTL_GET_NTFS_VOLUME_DATA and FSCTL_GET_RETRIEVAL_POINTERS valid as dwIoControlCode for DeviceIoControl() on NT4?

Are FSCTL_GET_NTFS_VOLUME_DATA and FSCTL_GET_RETRIEVAL_POINTERS0 valid as dwIoControlCode for DeviceIoControl() on NT4?

The reason I ask is that the Platform Documentation incdicates it is only available on Windows 2000 and XP. However, the include file "winioctl.h" indicates it is available on NT4 and above.

Which is true ?

Has anybody got NT4 with which to verify the solution.

azroles.dll anyone?

I'm using the Runtime azroles.dll to implement some Authorization Management stuff on Win2K. I'm trying to implement the example code from MSDN that can be found at

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/security/security/openprocesstoken.asp

Everything runs fine right up to the call to AccessCheck(...) and there I get E_INVALIDARG with all the parameters set up exactly as in the example code. As I don't have sources, I can't debug and I have no idea which argument is invalid.

Has anyone written any code for this piece (from the MS sample) that works?:

//  Check access.<br />
hr = pClientContext->AccessCheck(<br />
    objectName,<br />
    myVar,<br />
    varOperationIdArray,<br />
    myVar,               // use default application scope<br />
    myVar,<br />
    myVar,<br />
    myVar,<br />
    myVar,<br />
    &varResultsArray);

Could you show me how you passed in the various arguments?
Many thanks

I've been asked to display a variable's value every 30 seconds on stdout in the same display position on the same line of stdout without advancing the display position. I'm new to C++ and don't know how to begin with this. Please help! Sigh | :sigh:

Try this code:

for (int i = 0; i < 1000; i++)
{
    std::cout << i << '\r';
    Sleep(30 * 1000);
}

Which is what \r does. Had \n also been speciifed, then it would have gone to the beginning of the next line.

if you are in DOS mode
you can use
gotoxy(x, y) function

like
gotoxy(24, 12);
cout<<"First 30 ";
//30 sec delay logic here
gotoxy(24, 12);
cout<<"Second 30 ";

that will output in the same screen coordinate

The returned pointer may be temporary and should not be stored for later use.

UNICODE problem

Hi all

I have the following problem :
I cannot set dialog items text (like STATIC TEXT) to UNICODE (CWnd::SetWindowText is working but the displayed text is not readable ) .Interesting is that when I call SetWindowText directly on the CDialog the dialog's title is readable , but when I call the same method on any dialog element it will display unreadable text.

Anyone has any idea?

If they're in the same window station, I believe so.

However, I think you're talking about communications between computers, in which case you need to use some form of Remote Procedure Call.

playing a movie in a dialog-box?

cristane7-Apr-04 6:06

Hi. I have a question: how can I play a mpeg movie inside a dialog box, from a SDI application?

I tried the "easy" way... and it doesn't work...

(here's the "easy" way: after creating the dialog box, and the OnSomething function, and importing CMediaPlayer, I wrote this code:

CMediaPlayer dlg;
dlg.CreateWindow (.....yadda yadda...);
dlg.ShowWindow (WS_SHOW);
dlg.m_player.Open ("Test.mpeg");
dlg.m_player.Play ();

The funny thing is.... it works fine for a dialog-based application - when I write the last 2 lines of the above code, in the OnInitInstance() function.

Any suggestion welcome. (as you can see, I'm not a great programmer, so please don't laugh )

Thanks.

OnInitInstance is related to the application thread... there i guess it would have any effect.

humm as far i have understood this could be the solution..

Create an sdi application with form view and then place the mov player and do the coding for it like a normal dialog application in the view.
