At the risk of annoying whoever posted on this subject yesterday:

enum { MAX_SPEED = 500 };

The ability to initialise a constant within the class declaration was added to C++ quite late in the standardisation process, and VC6 doesn't support it.

Doubt in Property Sheets

Hi all,

I have one doubt in creating the wizards using property sheets. In my application i created the three property pages (dialog) with the size of 250x175. But whenever i included with the property sheet, i can't fix the size of the property sheet. How can i rearrange size property sheet.

And i have one more doubt.. Whether it is possible to place the "Back" and "Next" button in the customized position. I would like to place the "Back" button on the Top Left corner and "Next" button on the Top right corner. Whether it is possible ?

Waiting for ur reply

Regards,
Prakash

The size of a property sheet is governed by the size of the largest property page. Are you wanting to differ from that?

Ddraw.h causing ambiguous symbol error

I am trying to learn DirectX DirectDraw, but when ever I include ddraw.h I get ambiguous symbol errors. The errors point to the following files and items:

ObjIdl.h
	BIND_OPTS
	STATSTG
RpcAsync.h
	FILETIME
ServProv.h
	IServiceProvider

I do not get these errors if I comment out the ddraw.h.

Any help would be great.

CANT SAY 4 SURE BUT JUST TRY THE FOLLOWING:

Make sure you have included the appropriate library files in your project.
In VC++ IDE, Select PROJECT>SETTINGS>LINK
Then add these library fils to the list of existing files:
1.ddraw.lib
2.dxguid.lib

Another problem may be with the static compile option. Make sure u havent included ddraw.h in any other file of ur project.

Debuging a service with VC++

Hi all,

I have written a simple service and would like to debug it with VC++. Is this possible? So far I have only managed to do it by installing a low-level debugger but that's a bit akward to use.

Thanks,

Mark

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?

Dave Tyldesley7-Apr-04 7:25

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
dave

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:

    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?
