Kindly Help me.

Hello Sakthiu,
First of all you must register that service.
Then, once it is registered, you can go to the [start menu]->[Setup]->[administrative tools]->[Services] and start the desired service.
You can find information here in the CP in order to register a service.
Hope this helps.

if (bDelete)
return TRUE;

return FALSE;
}
Hope this helps.
I think I've missed the name, you must not register the service, you must install it before being able to start it.

I am using VC++ 6.0
The Visual Studio documentation states unequivocally:
Declarations of pointers to structures and typedefs for structure types can use the structure tag before the structure type is defined
Then
A member cannot be declared to have the type of the structure in which it appears. However, a member can be declared as a pointer to the structure type in which it appears as long as the structure type has a tag. This allows you to create linked lists of structures
I have two structures containing pointers mutually to each other, one of them containing a chaining pointer to itself as well.
I receive very strange syntactical error messages in the references to these pointers, for example referring to some left bracket, "(", (not present in the reference) and alike.
I tried with an incomplete definition, like
struct anystructure;
before the structure using the other, but it did not help. The error messages slightly change, but that's it.
Is this a known problem?

What's the error message ?
Yes, any type you can have as a pointer before it's declared, but it needs to be declared before you *use* the pointer. The point ( no pun intended ) is that the compiler can allocate space for a pointer before knowing how big the object is, but it can't access the object before it knows about it.

I guess your "The point ( no pun intended ) is that " is meant "The point ( no pun intended ) is NOT that ".
The declarations are in headers, far before the actual references. Other fields of the same structures can be referenced.
|

|

No, I meant what I said. The compiler can allocate a pointer before knowing what it's pointing to, but it can't use an object it knows nothing about.

OK, I understand how you meant "the point". That's all trivial, as a pointer is always four bytes long, at least with VC6.
As I indicated in my original post, all declarations are ahead.

Yeah, that was my point.

OK, then you have a different problem, which we can't help you with, without seeing the code.

Can you post code causing "very strange syntactical error messages " and maybe the struct
definitions including the relevent circular reference?

No, I can't. It's too large and depending on too many components. One of the errors is
H:\RawProc\TIFFProcessing.cpp(856) : error C2059: syntax error : '('
but this is on it's own useless. Some of the error messages are simply crazy (not fitting to the actual situation).
If I can't find a solution, I will create an abstract example and post that.

Something else is likely wrong - the location of that error (line 856) leads me to believe something else is going on here.
You may have to post all of the related code, or at least provide a way to get to it.
Edit - or at least lines 850-560...!
Peace!

It seems to be syntaxical one. Post some relevent code.

I created a simple example:
<br />
void main()<br />
{<br />
<br />
struct SampleStr2<br />
{<br />
char Anything;<br />
SampleStr2 *pNextStr;<br />
SampleStr1 *pSStr1;<br />
};<br />
<br />
struct SampleStr1<br />
{<br />
char Anychar;<br />
SampleStr2 *pSStr2;<br />
};<br />
<br />
return;<br />
};<br />
The error report is
<br />
error C2143: syntax error : missing ';' before '*'<br />
error C2501: 'SampleStr1' : missing storage-class or type specifiers<br />
error C2501: 'pSStr1' : missing storage-class or type specifiers<br />
|
|
|
|
|
void main()
{
struct SampleStr1;
struct SampleStr2
{
char Anything;
SampleStr2 *pNextStr;
SampleStr1 *pSStr1;
};
struct SampleStr1
{
char Anychar;
SampleStr2 *pSStr2;
};
return;
};

I DID do it so, as I wrote it in the original post (my addition, that this did not correct the error was wrong).
My main point was and is, that this contradicts the MS VC++ 6.0 documentation.
|
|

So what's the point of your post then? If you need help with a problem, a solution has been provided. If you're just wanting to rant about MS's documentation, take a number. It's a known fact that you can't rely 100% upon MSDN documentation. While errors are rare, they do occur and thus you should be prepared to make corrections.

The docu of VC++6.0 is miserable, but that's not the same as factually erroneous. I haven't got used to the idea of fighting against factual errors in the documentation.
However, in fairness I have to say, that this is not an error in the docu. After re-reading the documentation, I realized it: it states only that the definition does not have to be prior the pointer, but it says nothing about the declaration.

To add to Joe, This proves, its always better to provide problem code snippet.

I am using Sleep(10) in my thread to post a windows message every 10ms.
In the function responding to the windows message, I find that it is being executed approximately every 16ms. Where does the 6ms delay come from? My computer is not the best 1.53GHz, but 6ms delay is still way too slow.

Posting a message puts it in a queue; the speed at which the messages are removed from the queue by the receiving thread need not be directly related to the rate at which they're posted. For example, factors such as the time taken to process the message and thread scheduling come into play.

Is there a way to accurately predict the actual time it takes to post a message? The function I'm using is depended on that time.
Is there another way I can force the function to execute at specified time intervals, and accurately? Is there something like time() that would return ms instead of seconds?

It doesn't take long to post a message as it's simply queued. The delay comes into play because of the contents of the queue, the speed at which the receiving thread calls GetMessage and processes the message and thread scheduling.
acerunner316 wrote: Is there another way I can force the function to execute at specified time intervals, and accurately?
Probably the most accurate way would be to use a dedicated high priority thread which calls the function directly then sleeps, in a loop. Naturally if the approach is feasible or not in your case depends on what your function does.

Check out GetTickCount.

The reason I am posting a message and not directly calling the function is because the function references members of the main class, and I remember reading somewhere that you can't do that in a thread. So how can I create a dedicated thread that calls the function directly.
Thanks.
