hi,all:
i create a service,and my service must depend on two other service.
in function CreateService():
SC_HANDLE CreateService(
SC_HANDLE hSCManager,
LPCTSTR lpServiceName,
LPCTSTR lpDisplayName, // pointer to display name
DWORD dwDesiredAccess, // type of access to service
DWORD dwServiceType, // type of service
DWORD dwStartType, // when to start service
DWORD dwErrorControl,
LPCTSTR lpBinaryPathName,
LPCTSTR lpLoadOrderGroup,
LPDWORD lpdwTagId,
LPCTSTR lpDependencies, // pointer to array of dependency names
LPCTSTR lpServiceStartName, // pointer to account name of service
LPCTSTR lpPassword );
the Parameters of lpDependencies means:
lpDependencies
Pointer to a double null-terminated array of null-separated names of services or load ordering groups that the system must start before this service. Specify NULL or an empty string if the service has no dependencies. Dependency on a group means that this service can run if at least one member of the group is running after an attempt to start all members of the group.
You must prefix group names with SC_GROUP_IDENTIFIER so that they can be distinguished from a service name, because services and service groups share the same name space.
but i don't know how to do?who can give me a example.
appreciate any help!!!

I have a problem,
I am trying to write a function that reads a file, maipulates the data inside and then call it to the main() for an output.
okay the question looks something like:
1. There is a file say "filee.dat" it has 5 columns of numbers 1st column from 0 to 300. the rest correspond to it. 1st column is time,, the next is distance, the thrid is speed etc.
The thing is i need to write a function that calls this file and finds the time at which the distance starts decreasing (i.e the car is going forward but then after one high point, starts going back (so the distance decreases)).
SO from the main the output should be the time that corresponds to the the point where the distances starts to decrease.
Thansk!!

the file must have some structure.
a) the columns has a fixed size
b) the date is delimited with a special char maybe a ;
so yu have to read your file in a way, you can access the different values.... depending on the layout of your file.
|
|
|
|
|
so what would the code look like? there are columns for t,z,v,a and at places there are no values the but it goes from 0 to 300 with an interval of 0.5
the code is the thoing i am not clear of as in how to read it and how to acces the desired values.

no idea can anyone else help her?

not necessarily.
if each line looks like this : 50 312 125 423 12, you can easily read each entry (line) with a cin-like call.
<font style="color:blue;">int</font> id, speed, distance, time <font style="color:green;"> </font>;
file >> id >> speed >> distance >> time <font style="color:green;"></font>;
you now have all your values read in one line.

I am trying to avoid setting up the security auditing for each and eveyr PCs. Is monitoring the security event log the only way to do it? Any help is appreciated.

Hi David,
Thanks for the info. I think NetUserXXX suite of functions (including NetUserGetInfo and NetUserEnum) are for getting info about an existing resources. These functions maybe useful to poll against if a user has connect to your PC (this itself is a very useful info for my other project! Many Thanks!). However, having said it, I need to monitor in real time if any user a/cs has been created or modified. My aim is to protect against intrusion. As I have said, I could monitor the security event but I would need to set the auditing policy on each and every PCs (which I dearly would want to avoid the extra admin work).
More ideas?

hello i have a simple problem that i need to solve. i need to create a file, programmaticaly, with certain text. I am not sure if you can use static const char, but this is why i am asking. If anybody knows how to do this please help
I know i have to use CreateFile and WriteFile api but i need code that uses this

Use WIN32 File I/O API functions CreateFile and WriteFile for this purpose.

#include <iostream>
#include <fstream>
bool WriteTheFile ()
{
std::ofstream ofs ( "MyFile.txt" ) ;
if ( !ofs )
return false ;
ofs << "My file contains this text" ;
return true ;
}
Since the data is copied out to the file any text that is valid at the time of the write (in this case the '<<') can be written.
IMO if you're writing in C++ then it's worth becoming familiar with the iostream part of the Standard Libary and reserving direct use of the Win32 API for special cases where you really need something non-standard.

Hi,
I'm currently experiencing quite an odd problem.
I have this dialog (CDialog) which, among other things, contain a tree control and a property sheet. That is, I create the CPropertySheet dynamically by doing something like this:
<br />
m_interactionSheet.Construct("HEHE", this);<br />
<br />
m_actionPage.Construct(IDD_ACTIONS);<br />
m_eventPage.Construct(IDD_EVENTS);<br />
m_interactionSheet.AddPage(&m_actionPage);<br />
m_interactionSheet.AddPage(&m_eventPage);<br />
<br />
m_interactionSheet.Create(this, WS_CHILD | WS_VISIBLE);
The above code works without any problems. However, if I try to show another dialog after having called CPropertySheet's Create() function, the application locks up. It's like it goes into an infinite message loop or something :S
If I comment out the m_interactionSheet.Create() part I can create and display CDialogs again.. otherwise not.
EDIT: I have reproduced the behaviour in an ordinary SDI application. PLEASE have a look at it here:
http://www.blacksmith-studios.dk/PropertyTest.zip[^]
The problem is in the CInteraction::OnInitDialog() function. (BTW, this is just a test program so everything might be messy and all.. this problem is just killing me  )
Any idea what might be causing this as I'm all blank 
Thanks,

m_actionPage
m_eventPage
are these member variables of type CPropertyPage or a class derived from PropertyPage.
If so , i dont think construct is required, you can remove all three calls to constructs.
Then try. see if it works.

Hmm.. you're probably right about the Contruct() thing since both m_actionPage and m_eventPage are classes derived from CPropertyPage.
However, it didn't work. The application still locks up if I try to display another dialog.
I did observe something strange though. If I comment out the m_actionPage part and only go for the m_eventPage part, everything works :S
I did just discover, however, that if I put controls on the property page dialog template THEN it locks up again.
What the hell is going on here?

humm, things are going out of my hand now, did you enable the propertypage as popup window.

Yes, no difference there 
Do you mind if I add you to my MSN contact list? Just so we can discuss this more directly (if you have the time and want to, of course  )
Thanks for your time so far!

I have the following declaration
CMap<CString*, CString*, CStringArrayEx*, CStringArrayEx*> *m_EnhancementArray;<br />
What I am trying to accomplish is create a Map so I can take a string and get in return an array of other strings. I liked CStringArray but needed a copy constructor so that is what CStringArrayEx is all about.
The problem is when I set a value to this map using the following
m_EnhancementArray->SetAt(&returnVal, &EnhancementArray);<br />
returnVal is of course the string I have made as my key and EnhancementArray is my CStringArrayEx of strings. This call seems to work fine. When I iterate through the map, from the function where I called SetAt, I can see the data. However once I leave the function where SetAt is called, the data becomes corrupted in the CMap. I tried this without using a pointer and I still get the same thing to happen. Does anyone know what might be causing my data to disappear?
Thanks!

could you give a piece of your code so that we can see where could have been your fault...

In a sense, you kinda got it. I cut out the gory details cause they didn't make a shread of difference but I will try to put in the details I think would.

<br />

<br />
<dd> return *this;<br />
}<br />
<br />

<br />

<dd> }<br />
<br />
<dd> CStringArrayEx& operator =(const CStringArrayEx& pCopy);<br />

<br />
...
<br />
<dd> CMap<CString*, CString*, CStringArrayEx*, CStringArrayEx*> *m_EnhancementArray;<br />
<br />
};<br />
I hope this helps.

something to add. I can now see the data when I am outside the function. I can iterate through and actually get the first key and the value associated with it. however when I try Lookup, it fails. The only difference I can spot is that when I iterate I am using a CString *var; When I am using lookup it is a CString var, however if you notice I am sending the address pointer Lookup(&stringVar, ArrayVar).
Does this make any sense?
Thanks

Why are you using CString* as the KEY and the ARG_KEY parameters of the CMap template. Declare it as CMap<CString, LPCTSTR, CStringArrarEx*, CStringArrayEx*> *m_EnhancementArray in your class declaration.
In your StoreEnhancements function, change m_EnhancementArray->SetAt(&returnVal, &EnhancementArray) to m_EnhancementArray->SetAt(returnVal, &EnhancementArray).
And, in your GetEnhancement function, change CString *Keys to CString Keys.

It looks like that did it. Thanks! I actually did try changing the CMap to CString but I did for both parameters. I never thought of using LRCTSTR however.
