If you read my post more carefully, you could see that I didn't say that there is no problem with LockWorkStation() at all, I said that I haven't encounter a problem with it

Mike did read your post (perhaps you inadvertently asked the wrong question). He was politely telling you that if LockWorkStation() behaved as you wanted, imagine the security hole that would be created.

wildcard interpretation

Hi everybody,

I am currently working on a program for which I need to select filenames based on a template that can include wildcards. Since I get the filenames in a fixed list from another system, I cannot use the wilcards in retrieving the filenames in the first place. I would like to use wildcards the "Unix way", which means that for example "ABC*DEF*G?I.xyz" would be a possible wildcarded template to which not anything starting with ABC should match!
Of course, I can write such an algorithm, but since I am lazy, I would appreciate if anyone out there knows of a library that will do the job? Would save me a lot of work!

Thanks in advance!

William

wildcard interpretation == "globbing" (yeah, I know - don't ask me where the name came from).

This CodeProject article[^] has (or claims to have) globbing code.

PostMessage with VISTA

Hi,

I am trying to post a message from one application to another using PostMessage().
I is working fine in XP and Vista (UAC disabled) but it is not working with Vista(UAC Enabled).

Anyone can tell me, how to use it?

Stuart Dootson6-May-09 2:19

6-May-09 2:19

Well, from the documentation[^]:

Microsoft Windows Vista and later. Message posting is subject to User Interface Privilege Isolation (UIPI). The thread of a process can post messages only to message queues of threads in processes of lesser or equal integrity level.

I guess you need to elevate the privileges of the sender to at least those of the receiver before the PostMessage

Hello All,

When I am executing the following code

SC_HANDLE schSCManager, schService;
TCHAR szPath[MAX_PATH];

GetModuleFileName(NULL, szPath, MAX_PATH);
schSCManager = OpenSCManager(NULL, NULL ,SC_MANAGER_ALL_ACCESS);

if ( schSCManager == NULL )
    return false;

schService = CreateService(schSCManager, USER_SERVICE_NAME, USER_SERVICE_NAME,
    SERVICE_ALL_ACCESS,SERVICE_WIN32_OWN_PROCESS,SERVICE_DEMAND_START,SERVICE_ERROR_NORMAL, szPath, NULL, NULL, NULL, NULL, NULL);

The

CreateService()

is not returning a proper handle. When I used

GetLastError()

, its throwing a

ERROR_ACCESS_DENIED

error. Please help in solving this issue.

Thanks in advance,
Neelesh K J Jain.

Are you executing this from an account with administrator access?

Yes, I have the administrator access.

Stuart Dootson6-May-09 2:23

From the documentation[^]:

ERROR_ACCESS_DENIED The handle to the SCM database does not have the SC_MANAGER_CREATE_SERVICE access right.

That implies that when you called OpenSCManager[^], you didn't ask for the SC_MANAGER_CREATE_SERVICE access right.

Hello Stuart,
I tried even with SC_MANAGER_CREATE_SERVICE access right, then also I am getting same error code as access denied.

'even with'? That access right (implied by SC_MANAGER_ALL_ACCESS) is absolutely necessary for creating a service. And you did include it in your call to OpenSCManager, right?
