Hi all,
I want to enumerate all the users in the domain from my service. I tried
using NetUserEnum and NetQueryDisplayInformation functions but it fails
with access denied. When i run the functions from the console application, it
works fine but from my service (which runs under local system account) it
fails......How do i get around this???.....Is there some other way of
enumerating users of a domain from the service???

Then run your service from an account with sufficient access rights

I didnt get it...i thought local system account is the most powerful account with all the rights.....I guess only problem is that only authenticated users are allowed to query the domain but in this local system is not a authenticated user.....Is there some other way of enumeration??

If it's a security issue then it should fail regardless of what method you use to enumerate.
I would first verify that security is the problem - a breakpoint and check the error code should
do it.
The LocalSystem account may have high priveledges on the local computer but not on the network.
Actually, I'm pretty sure you can't access the network with that account anymore (I may be
confusing it with another account).
It's recommended these days to use specific accounts to run services under which have just the
needed access rights and no more.

As i said in previous post...i checked the return code and it said....access denied..so i know the problem now...since local system is not authenticated to query the domain, the api will fail...
According to what you are saying, i need to add an (fake) account to the network and then run the service under that fake account to query the domain....this really doesnt look that great idea because then what i means 1) i am adding a non existent user in the network 2) all machines on the domain where my service is running will need to have that account in local machines (which can be a big risk)
So is there some other way of doing it??

Sorry about that
There's no more risk really. If it worked from the console (meaning you had adequate permission)
and every other user has the permissions then there's no difference.
I trust services I write WAY more than I'd trust any user with enhanced privileges.
Only the service runs in the context of the "fake" account, not the users that log in on the
machine. I'm rusty on my limited IT skills but on a domain can't an account be created on the
domain server and managed there instead of having to add an account to every machine?
Yes managing extra accounts is a pain - you can thank all the hackers that have taken advantage
of security holes in Windows for that. The localsystem acount used to have many more privileges.

OpenGL comes with the drivers for your graphics card, if the graphics card supports that level of OpenGL. If your graphics card does not support it, level 1.2 is supported through software emulation under Windows XP/Vista and 1.0 under 2000. If you are looking for library support for OpenGL, they are available for each compiler through sites specific for that compiler. Which are you looking for?

You must add the .lib file to your project: Project/Settings/link, write your name of .lib file to Object/library modules:
|
|
|
|
|
the library you're using requires your application to link with multithreaded C run-time libraries. Use the /MT compiler option
(for instance, on Visual Studio 6, choose menu Project->Settings, then on the C/C++ tab, add /MT in the Project Options list).
hope that helps.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Add MT in ur project settings as rightly suggested which means support for Multithreading in ur project. Happy coding

Hello All-
I'm working on a SQL database application. The database contains a main table of information, and then each table has another set of data associated with it from another table. What I'd like to do is keep a maximized view of the main table of data open at all times (just like with SDI), and then be able to open up in MDI-like child views of each subset of data associated with an item in the main view.
Another way to describe what I want would be to say I want MDI with the root main frame window also containing a view in it.
Please give me any suggestions you can.
Thank You!

I am doing a multi-column listbox,I set its styles:OwnerDraw-Fixed,Multi-column and "No integal height".Then I add virtual function MeasureItem and add code :
void CColorListBox::MeasureItem(LPMEASUREITEMSTRUCT lpMeasureItemStruct)
{
// TODO: Add your code to determine the size of specified item
CRect rect;
GetWindowRect(&rect);
ScreenToClient(&rect);
lpMeasureItemStruct->itemHeight=rect.Height()/2;
lpMeasureItemStruct->itemWidth=rect.Width()/4;
}
I add a member function to initialize the data and call this function in PreSubclassWindow:
void CColorListBox::InitData()
{
SetItemData(0,RGB(255,0,0));
SetItemData(1,RGB(0,255,0));
SetItemData(2,RGB(0,0,255));
SetItemData(3,RGB(125,0,0));
SetItemData(4,RGB(0,125,0));
SetItemData(5,RGB(0,0,125));
SetItemData(6,RGB(125,125,0));
SetItemData(7,RGB(125,125,125));
}
The last I do DrawItem:
void CColorListBox::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{
// TODO: Add your code to draw the specified item
CDC* pDC=CDC::FromHandle(lpDrawItemStruct->hDC);
UINT action=lpDrawItemStruct->itemAction;
UINT state=lpDrawItemStruct->itemState;
CRect rcItem=lpDrawItemStruct->rcItem;
//pDC->SetBkMode(TRANSPARENT);
if( !(state&ODS_SELECTED) )
pDC->FillSolidRect(&rcItem,(COLORREF)lpDrawItemStruct->itemData);
}
Is there something wrong in my operation?I set a breakpoint in MeasureItem and debug the program,but it don't run through the breakpoint?
I appreciate your comments~
